Technical field

The technology is related to wirelessly communicating, more particularly in wireless communications for requesting, transmitting and using system information (SI) method and apparatus.

Background technique

In a wireless communication system, radio access network generally includes one or more access nodes (such as base station), The one or more access node passes through radio or air interface over a radio channel and is communicated with multiple wireless terminals. In some technologies, such wireless terminal is also referred to as user equipment (UE).Referred to as the 3rd generation partner program (" 3GPP ") Group, which has promised to undertake, defines globally applicable technical specification and technical report for current and Next-Generation Wireless Communication Systems.3GPP is long-term Evolution (" LTE ") and the advanced LTE of 3GPP (LTE-A) are to improve early stage Universal Mobile Telecommunications System in a manner of meeting tomorrow requirement The project of (" UMTS ") mobile phone or equipment standard.

International Telecommunication Union (ITU) and 3GPP have taken up to formulate new radio (NR) 5G system (such as the 5th generation system System) requirement and specification.In the range of 3GPP, having had been approved by new research project (SID), " new radio access technologies are ground Study carefully ".The timetable and research conditions of NR exploitation are summarised in RP-161596, " Revision of SI:Study on New Radio Access Technology ", 3GPP TSG RAN meeting #73, New Orleans, September 19 to 22 in 2016.For Meet 5G requirement, it has been proposed that the variation about 4G LTE system for studying, such as higher frequency spectrum use (for example, 6GHz, 40GHz or up to 100GHz), expansible parameter (for example, different subcarrier spacings (SCS), 3.75KHz, 7.5KHz, 15KHz (current LTE), 30KHz...... may 480KHz), the initial access based on wave beam is (due to using particular beam shape At a conventional cell may include multiple wave beams).

In LTE system, it is classified synchronization signal, i.e., main synchronizing sequence (PSS) and secondary synchronization sequences (SSS) provide rough Time/frequency is synchronous, physical-layer cell ID (PCI) identification, subframe timing identifies, frame structure type (FDD or TDD) is distinguished and followed The identification of ring prefix (CP) expense.On the other hand, in traditional LTE system, in, Physical Broadcast Channel (PBCH) provides further Information, such as System Frame Number (SFN) and fundamental system information, so that wireless terminal (for example, UE) can obtain access network Information.

In LTE system, three PSS sequences provide the identification (0-2) of cell ID；And SSS sequence provides cell ID group Identification (0-167).Therefore, in all 168*3=504, LTE system supports PCI ID.

It is expected that cell corresponds to one or more transmission and receiving point (TRP) in next-generation new radio (NR) technology. This means that multiple TRP can share identical NR cell ID or each transmission and receiving point (TRP) can have their own Identifier.In addition, the transmission of a TRP can be the form of simple beam or multi-beam.Each wave beam may also have it certainly Oneself identifier.Figure 14 provides the simple examples description of relationship between cell, transmission and receiving point (TRP) and wave beam.

Opinion is already agreed upon in RANI#86bis meeting (see, e.g., the note of 3GPP chairman RANI#86bis Release):

PSS, SSS and/or PBCH can the transmission in " SS block "

ο is not excluded for being multiplexed other signals in " SS block "

One or more " SS block " compositions " SS train of pulse "

One or more " SS train of pulse " compositions " SS pulse trail "

SS train of pulse number in ο SS pulse trail is limited.

From the perspective of RANI specification, NR air interface define SS pulse trail at least one in period (note: The interval of SS train of pulse can be identical as the interval of the SS train of pulse set in some cases, for example, simple beam operates)

Fig. 1 is the example NR SS block structure according to RANI#86bis meeting.In Fig. 2, " synchronous signal impulse string sequence " It indicates " SS pulse trail ".Additional detailed example is in Rl-1610522 " WF on the unified structure of DL Shown in sync signal ", Intel company, NTT DOCOMO, in it is emerging, in emerging microelectronics, ETRI, InterDigital, Portugal Grape tooth Lisbon, 10 to 14 October in 2016.

Therefore, as indicated above, one or more " SS block " composition " SS train of pulse " one or more SS pulses String further constitutes SS pulse trail, and wherein the quantity of the SS train of pulse in SS pulse trail is limited.If existed always The case where one SS train of pulse constitutes SS pulse trail, then being practically without the meaning for defining SS train of pulse, or does not need The definition of SS train of pulse.From the perspective of physical layer specification, the periodicity of at least one SS pulse trail is supported.From the angle of UE From the point of view of degree, the transmission of SS pulse trail is periodic, and UE assume that and be repeated cyclically given SS block with SS pulse trail, This means that SS block can have the periodicity different from SS pulse trail.

According to the annotation of 3GPP chairman RANI#87, further agree in [4], from the perspective of UE, SS train of pulse Collection transmission is periodic, and at least initial cell is selected that UE assume that the SS pulse for given carrier frequency The default cycles of trail transmission.

In LTE, PSS/SSS and PBCH due to different detection performances require and the distinct methods of confrontation channel distortion and With different periodicity (PBCH has channel coding and repetition, and to fight channel distortion, and PSS/SSS does not have).

Initial cell selection for new radio (NR) cell, UE assume the default SS pulse trail of each frequency carrier Periodically.In cellular networks, CONNECTED mode UE may need to measure (RSRP/RSRQ or their equivalent survey Amount), to execute switching；And IDLE mode UE may need to measure, to execute cell selection/reselection.In traditional LTE system In, SS transmission only has a fixed cycle property (5ms) in the entire network；In NR system, one group of SS pulse trail is come from A periodic value can be configured to UE.

For the UE (already being resident within the UE in NR cell) of CONNECTED and CONNECTED mode, new radio is supported The periodic network instruction of SS pulse trail and the information for exporting the measurement timing/duration for NR-SS (for example, examine The time window of survey).If it would be possible, the network is periodically believed to the SS pulse trail that UE provides each frequency carrier Breath, and the information for exporting the measurement timing/duration is provided.It is indicating a SS pulse trail periodicity and is indicating In the case where an information about the timing/duration, UE assume all cells on same carrier wave periodicity and timing/ Duration.If network does not provide SS pulse trail, periodically and for exporting the finger for measuring the information of timing/duration Show, then UE is it will be assumed that 5ms is periodical as SS pulse trail.New radio supports one group of SS for the instruction of adaptive and network Pulse trail seasonal values.

In order to detect dependent NR cell (for example, the NR carrier wave being initially accessed or UE is not supported to will not reside in NR cell On other reasons), NR-SS still can at least be used for cell identification and initial synchronisation and CONNECTED mode RRM and survey Amount.Similarly, for the UE of CONNECTED and CONNECTED mode, NR support the periodic network instruction of SS pulse trail and For exporting the information (for example, time window for NR-SS detection) of measurement timing/duration.If it would be possible, should Network provides a SS pulse trail periodical information of each frequency carrier to UE, and provide for export measurement timing/ The information of duration.In one information that SS pulse trail is periodical and instruction is about the timing/duration of instruction In the case where, UE assumes periodicity and the timing/duration of all cells on same carrier wave.New radio supports one group of use In the SS pulse trail seasonal values of adaptive and network instruction.

In view of the foregoing, however it remains various technical problems and challenge.Such as:

(1) if UE SS pulse trail is periodically assumed it is different from network configuration, especially when update cell in Is SS pulse trail periodical, and when periodicity is changed into other values from default value, what is to be done

(2) if more than one periodicity/timing/duration and UE can be configured not about its priori for UE Information, what is to be done

(3) if different cells is periodical configured with different SS pulse trails, especially if neighboring community configures There is different frequency carriers, what is to be done

Therefore, the example object of presently disclosed technology is to solve the method, apparatus of one or more aforementioned techniques challenges And technology.

As used herein, " synchronizing information " generally cover synchronization signal, synchronization signal block, synchronous signal impulse string with it is synchronous One or more of signal bursts collection, as with reference to Fig. 1 and its it is discussed above understand as.In view of such general art Language, as used herein, " synchronizing information seasonal values " are covered and therefore include (1) synchronous signal cycle value, (2) synchronization signal One of burst periods value, (3) synchronous signal impulse trail seasonal values and (4) (1) to any combination of (3) or More persons.Therefore, synchronizing information seasonal values clearly include but is not limited to that synchronous signal impulse trail is periodical (SSBSP).Thing In reality, as used herein, term (1) to (4) is used interchangeably.For example, " SS pulse trail is periodically (SSBSP) " is mentioned herein It can indicate SS pulse trail periodicity or SS burst periods or SS periodicity or any combination of them.Simply to rise See, SSBSP can be used to show in time simplify and conveniently.Herein to the reference of " base station " can be expressed as such as gNB or GNB or eNB.

From the perspective of UE, the transmission of SS pulse trail is periodic.Initial cell is selected, UE assumes for giving Determine the default cycles (Xms) of the SS pulse trail transmission of carrier frequency.One is only defined for each given carrier frequency A default cycles (T_default).

SS pulse is supported for the UE (already being resident within the UE in NR cell) of CONNECTED and CONNECTED mode, NR The instruction of trail periodic network and for export the measurement timing/duration information (for example, be used for that NR-SS to detect when Between window).

In existing system, the periodicity of synchronizing information be can be uniformly, therefore in entire radio access network It is known.In addition, synchronizing information can keep constant and will not change in existing system.But described herein In system and technology, different cells can have different synchronizing information seasonal values.For example, with same carrier frequencies Different community (intra-frequency cell) and/or different community (inter-frequency cell) with different carrier frequencies can have different Synchronizing information seasonal values.In addition, network can change synchronizing information seasonal values every now and then for particular wireless station.

Use that is different and/or changing synchronizing information seasonal values may connect derived from wireless terminal Consideration with radio Enter the tension between network considerations.For example, wireless terminal supplier may want to wireless terminal use it is relatively short same Property information cycle value is walked, to keep the synchronous detection performance of good wireless terminal and therefore quick access network.

On the other hand, radio access network operator, which may prefer to network, has higher synchronizing information periodical Value, so that radio access network does not need continually to transmit synchronizing information seasonal values, without by net as much Network resource is for synchronizing.For example, network operator can determine that professional qualification to need to minimize signaling, therefore network operation Quotient can configure one or more cells of network to change into longer synchronizing information seasonal values.Longer synchronizing information Seasonal values generally mean that less synchronous signaling business.Alternatively, it is understood that there may be the less busy time (example of network Such as, night), and operator tends to allow have shorter synchronizing information seasonal values in some cells.Shorter is same Step property information cycle value in turn means more synchronous signaling business.

As described above, wireless terminal wirelessly can receive wireless communication in generic scenario, which includes synchronizing Signal message, the synchronizing information which uses according to the node in the air interface of radio access network Seasonal values transmission.Wireless universal terminal is configured as default synchronizing information seasonal values and section when wireless terminal has used The synchronizing information seasonal values that point uses do not detect synchronous signal information simultaneously.The more specific feelings of various examples are described below Condition, comprising: (A) change/update synchronizing information seasonal values wireless terminal；(b) different synchronizing information seasonal values are solved The use of network and terminal；And (C) wireless terminal obtains the synchronizing information seasonal values of neighboring community.

A. wireless terminal changes/updates synchronizing information seasonal values

Fig. 2A depicts the case where network expectation changes the synchronizing information seasonal values that wireless terminal is operating, for example, The second synchronous signal impulse trail seasonal values are changed into from the first synchronous signal impulse trail seasonal values.For example, network (example Such as, the radio access node 22 of Fig. 2A) it will be seen that the default synchronous signal impulse trail period is used in wireless terminal 26 Property value, and network wish indicate wireless terminal 26 change into using update synchronous signal impulse trail seasonal values.Fig. 3 A is extremely Fig. 3 F shows certain communication systems, and wherein wireless terminal changes into the second synchronizing information week from the first synchronizing information seasonal values Phase property value.

The wireless terminal 26A of Fig. 3 A is equipped with the first synchronizing information seasonal values but can believe from using first to synchronize The wireless terminal that seasonal values change is ceased, to use the detection of the second synchronizing information seasonal values from radio access network (example Such as, from radio access node 22) at include in received wireless communication synchronization signal.Terminal handler 40 includes that terminal is same Processor 56 is walked, the terminal synchronous processing device is after and including terminal periodic value selector 58.Terminal synchronous processing device 56 is deposited Storage or access both the first synchronizing information seasonal values and the second synchronizing information seasonal values.It is specific in example, non-limiting example In implementation, the first synchronizing information seasonal values include default synchronizing information seasonal values 60 (for example, T_default), and the Two synchronizing information seasonal values include updating synchronizing information seasonal values 62 (T_update).

Foregoing example embodiment and mode show certain sample situations, including update synchronizing information periodicity by network It is worth (for example, SSBSP).Foregoing example embodiment and mode cover but are not limited to following optionally detailed design:

Optionally A. is for given carrier frequency, and in addition to T_default, there are also another SSBSP to define (T_update). The value of T_update can be predefined, can also be configured by network from one group of SSBSP value.

Optionally A.1 > as predefined T_update, UE also is understood that the value of T_update, thus without going through gNB to UE is signaled；On the contrary, some events, which can trigger UE, is periodically detected SS/SS pulse trail with what is updated.It is one below The example of " event " a bit:

Embodiment 1: in broadcast signaling and/or dedicated signaling to CONNECTED mode UE or IDLE mould is arrived Include an information element (IE) in the broadcast signaling of formula UE, indicates that current SSBSP is T_default or T_update, for example, " 0 " indicates T_default, and " 1 " indicates T_update.

Embodiment 2: being that UE configures timer by broadcast signaling and/or dedicated signaling, to use whithin a period of time Default SSBSP；Expiring for timer indicates that UE should use the SSBSP detection SS updated.In this case, update is being used In the duration of SSBSP, it is understood that there may be allocated to another timer of UE in the same manner；Timer, which expires, indicates that UE is answered Use default SSBSP.

Alternatively A.2 > when network from multiple values configure T_update when, UE without SSBSP value priori knowledge.This In the case of, exist including in the dedicated signaling in broadcast signaling and/or to CONNECTED mode UE, or arrive IDLE mode Value in the broadcast signaling of UE indicates the new value of SSBSP.The value itself can trigger UE using the SSBSP detection SS updated, or Person's value may be combined with above-mentioned trigger event, for example, it will check new SSBSP really when UE is triggered to update SSBSP Cut value.

B. the network of different synchronizing information seasonal values and the use of terminal are solved

Fig. 2 B depicts network and synchronizing information seasonal values (SSBSP) is updated to other values from default value, for example, To the synchronizing information seasonal values (SSBSP of update) of update) the case where, and grade wireless terminal is initially accessed it is still assumed that operation Synchronizing information seasonal values are default synchronizing information seasonal values (default SSBSP).Particularly, in fig. 2b, it is wirelessly electrically accessed Node 22 is changed into from default synchronous signal impulse trail seasonal values (T_default) updates the synchronous signal impulse string period Property value (T_update), but the wireless terminal 26 of recent visit network (for example, arrive CELL) is still using defaulting synchronization signal Pulse trail seasonal values.

The example embodiment and mode of Fig. 6 A to Fig. 6 D solves the problems, such as shown in such as Fig. 2 B or situation, wherein net Synchronizing information seasonal values (SSBSP) are updated to other values from default value by network, for example, to the synchronizing information period updated Property value (SSBSP of update)) the case where, and be initially accessed grade wireless terminal it is still assumed that operation synchronizing information seasonal values be silent Approval step property information cycle value (default SSBSP).In the example embodiment and mode of Fig. 6 A to Fig. 6 D, unless otherwise indicated Or it is clear from the context, otherwise with the element of identical appended drawing reference should be managed with one or more of Fig. 3 A to Fig. 3 F Solution is structure having the same and/or function.

It may include that the synchronizing information seasonal values generator 70-6A of Fig. 6 A in synchronization information generator 54 is configured For the update synchronizing information seasonal values for selecting the default synchronizing information seasonal values less than radio access network.For example, same Step property information cycle value generator 70-6A can choose the update synchronizing information for defining or being configured with less than default SSBSP always Seasonal values (SSBSP value).For example, accessible " T_update " information element of synchronizing information seasonal values generator 70-6A, It includes one group of candidate value, and the maximum value in candidate value range is not more than the T_default of given carrier frequency.This In the case of, network more frequently synchronous signal transmission.Therefore, when still using default SSBSP, wireless terminal 26-6A may Miss some synchronization signals of detection.However, as presently disclosed technology as a result, the wireless terminal 26-6A of Fig. 6 A can be protected It holds and is initially accessed SS detection performance without significant adverse effect.

In addition, for the interests of wireless terminal 26-6A, and the update synchronizing information relatively short as combination is periodical The optional feature of value, the synchronization information generator 54 of radio access node 22-6A can make synchronization signal synchronous with default It is transmitted several times in the corresponding synchronization signal detection window of property information cycle value (because wireless terminal 26-6A still can consider behaviour Making synchronizing information seasonal values is default synchronizing information seasonal values).Therefore, using the optional feature, although wireless terminal 26- The synchronizing information seasonal values that 6A still can be used default synchronizing information seasonal values rather than update operate, and although Wireless terminal 26-6A still can be used and the corresponding synchronization signal detection window of default synchronizing information seasonal values, but nothing Line terminal 26-6A has more chance detection synchronization signals, because it is transmitted several times in synchronization signal detection window.For Fig. 6 A Example embodiment and mode, according to the optional feature, terminal synchronous processing device 56 can be configured as correspond to default Multiple receptions of synchronization signal are detected in the detection window of synchronizing information seasonal values.

It is unrestricted that Fig. 7 A shows the example representation that can be carried out or be executed by the radio access node 22-6A of Fig. 6 A Property movement or step.Movement 7A-1 includes radio access node 22-6A, which selects and/or using more New synchronizing information seasonal values, the seasonal values are less than the default synchronizing information period that wireless terminal 26-6A assumes and uses Property value.That movement 7A-2 includes radio access node 22-6A is multiple in the window for corresponding to default synchronizing information seasonal values/ The optional actions of synchronization signal are transmitted several times.

Fig. 8 A shows the non-limiting movement of example representation that can be carried out or be executed by the wireless terminal 26-6A of Fig. 6 A Or step.Acting 8A-1 includes wireless terminal 26-6A, uses default synchronizing information seasonal values, the default synchronizing information week Phase property value is greater than the synchronizing information seasonal values by the radio access node 22-6A update selected with synchronous signal transmission.It is dynamic It include that wireless terminal 26-6A detects synchronization signal in detection window corresponding with default synchronizing information seasonal values as 8A-2 Multiple received optional actions.

The synchronization information generator synchronizing information seasonal values generator 70-6B of Fig. 6 B may include wirelessly being electrically accessed section In the synchronization information generator 54 of point 22-6B, it is configured as the default synchronizing information period that selection is greater than radio access network The update synchronizing information seasonal values of property value.For example, synchronizing information seasonal values generator 70-6B can be configured as selection And/or using the synchronizing information seasonal values (the SSBSP value of update) updated, always it is defined or is configured to be greater than default together Walk property information cycle value (for example, the SSBSP for being greater than default).For example, synchronizing information seasonal values generator 70-6B is accessible " T_update " information element comprising one group of candidate value, and the minimum value in candidate value range is not less than given carrier frequency The T_default of rate.In the case where no adjusting, the wireless terminal 26-6B of Fig. 6 B may need more than one to default SSBSP To detect synchronization signal.Need more than one default SSBSP that may influence initially to visit within some predefined period Ask detection performance.But new radio needs quick initial access, so if not adjusting, wireless terminal 26-6B may not Section can be waited long enough for accumulate enough synchronization signal energy measurings, in this case, if do not adjusted, nothing Line terminal 26-6B possibly can not eventually detect synchronization signal.As a kind of possible technology, wireless terminal 26-6B can not It is provided for being greater than any adjusting of default synchronizing information seasonal values, so that wireless terminal 26-6B undergoes and may hold Bear some detection performance losses.In this regard, terminal synchronous processing device 56 can be in view of relative to default synchronizing information week The update synchronizing information seasonal values of phase property value adjust its detection performance standard.Fig. 6 B is shown, for example, terminal synchronous processing device 56-6B may include detection performance standard adjuster 120.Detection performance standard adjuster 120 can permit in some cases Synchronization signal detection is determined using less stringent standard, such as when the synchronous letter of synchronizing information seasonal values transmission with update Number when, which is greater than the default synchronizing information seasonal values that are used by wireless terminal 26-6B.For example, inspection Survey performance standard adjuster 120, which can permit, determines synchronization signal when detecting less energy associated with synchronization signal Detection, rather than in other cases.

It is unrestricted that Fig. 7 B shows the example representation that can be carried out or be executed by the radio access node 22-6B of Fig. 6 B Property movement or step.Movement 7B-1 includes radio access node 22-6A, which selects and/or using more New synchronizing information seasonal values, the seasonal values are less than the default synchronizing information period that wireless terminal 26-6A assumes and uses Property value.

Fig. 8 B shows the non-limiting movement of example representation that can be carried out or be executed by the wireless terminal 26-6B of Fig. 6 B Or step.Acting 8B-1 includes wireless terminal 26-6B, uses default synchronizing information seasonal values, the default synchronizing information week Phase property value is less than the synchronizing information seasonal values by the radio access node 22-6A update selected with synchronous signal transmission.It is dynamic It include wireless terminal 26-2B as 8A-2, which is adjusted using default synchronizing information seasonal values for detecting synchronization The detection performance standard of signal.

However, wireless terminal 26-6C shown in Fig. 6 C has some tune to the synchronizing information seasonal values for being greater than default Section.For example, the terminal synchronous processing device 56 of wireless terminal 26-6B includes synchronization signal detection performance enhancers 122.Synchronization signal Detection performance booster 122 can be realized in many ways.For example, synchronization signal detection performance enhancers 122 (connect with radio Ingress 22-6C coordinates) a type of SS sequence can be used, which is used to meet single and multiple SS detection performance is wanted Both ask.In the single detection scheme realized in some wireless terminals, it is only considered that the one-time detection foot of synchronous signal sequence To synchronize the final determination of signal detection.Alternatively, synchronization signal detection performance enhancers 122 can be by using respectively The SS sequence design of more than one type realizes single and repeated detection, for example, when SSBSP is updated to bigger value by network When, network transmission has the longer SS sequence of more preferable detection performance.Also there is wireless terminal 26-6C this to predefine information, with SS detection is carried out using different types of sequence.

As the example for the enhancing operation that can be executed by synchronization signal detection performance enhancers 122, synchronization signal detection It is to examine less than maximum subsynchronous signal that typical single synchronization signal detection can be operated modifications or changes by performance enhancers 122 Survey operation.Before synchronized signal detector definitely determines and in fact has been detected by synchronization signal, some synchronization signal inspections It surveys device and needs repeated detection synchronous signal sequence in detection window (for example, N, wherein N is integer > 1).It is specific in an example In implementation, to synchronization when the synchronization signal detection performance enhancers 122 of Fig. 6 C can be less than N number of detection number in determining window Signal is finally detected, and n times detection otherwise will be expected to it.In other words, same using default in terminal synchronous processing device 56 Step property information cycle value expection has accumulated which in the window of synchronization signal detection energy of Y integral multiple, on the contrary when receive with When the synchronization signal of the synchronizing information seasonal values transmission of update, allows terminal synchronous processing device 56 to accumulate less than Y times time SS and examine Survey energy.

It is unrestricted that Fig. 7 C shows the example representation that can be carried out or be executed by the radio access node 22-6C of Fig. 6 C Property movement or step.Movement 7C-1 includes radio access node 22-6A, which selects and/or using more New synchronizing information seasonal values, the seasonal values are less than the default synchronizing information period that wireless terminal 26-6A assumes and uses Property value.

In the scene of Fig. 8 D, wireless terminal executes certain tasks unlike the wireless terminal in the scene of Fig. 8 C.In In the scene of Fig. 8 C, wireless terminal may must detect more synchronization signal copies in a SS pulse trail, because Network will be configured correspondingly.

Radio access node 22-6D shown in Fig. 6 D also uses or selects the synchronizing information seasonal values updated, should The synchronizing information seasonal values of update are greater than default synchronizing information seasonal values.But radio access node 22-6D by Increased number of synchronization signal is provided in synchronous signal impulse trail to repeat to provide some adjustings for wireless terminal 26-6D, with Convenient for the detection of wireless terminal.In this regard, the synchronization information generator 54 of Fig. 6 D is shown as including for train of pulse list The synchronization signal repeater of member 130.Using the synchronization signal repeater for pulse string location 130, a SS train of pulse is carried More duplicate synchronization signals in collection, to realize better detection performance in a SS pulse trail.Wireless terminal 26-6D Also there is the predetermined information for the SS detection in SS pulse trail.For example, at the terminal of wireless terminal 26-6D is synchronous Managing device 56 includes detector 132, which is configured as the increased number of synchronous letter in detection synchronous signal impulse trail Number repetition.

At above-mentioned aspect, the concept of " more " and " accelerating " can be understood in the following manner: assuming that having default Periodical, the synchronization signal in SS pulse trail has X copy, and (x is greater than 0 integer, for example, usually 1).It is " more multiple It is multiple " it is meant that there are y synchronization signal copies compared with default cycles, wherein if update cycle property has than default It is worth bigger value, then Y > X.Number of repetition is known for wireless terminal, for example, being pre-configured with by network and/or being allocated to Wireless terminal, such as some instructions carried by SS pulse trail.

Fig. 9 also show terminal handler circuit 40 be configured as from radio access network transmit signal (for example, by Radio access node 22-9A transmission) at obtain neighboring community synchronizing information seasonal values.The terminal of wireless terminal 26-9A Processor circuit 40 specifically includes neighboring cell synchronization property value information cycle extractor 144.The neighboring community carried by signal 142 Default synchronous signal impulse trail seasonal values received by the acceptor circuit 46 of wireless terminal 26-9A, by frame processing routine 52 decode from the frame for formatting signal 142, are then accessed by neighboring cell synchronization property value information cycle extractor 144.Hereafter, Neighboring community can be used (for example, the CELL in Fig. 2 C in wireless terminal 26-9A₂) default synchronous signal impulse trail it is periodical Value with relative to from neighboring community (for example, the T_default in Fig. 2 C₂) received wireless communication synchronization signal detection process It combines.

In the example specific implementation illustrated in fig. 12, the default synchronous signal impulse trail period including neighboring community Property value signaling 142 include neighbor cell list 150.As illustrated in fig. 12, neighbor cell list can use the form of table, The table includes the default synchronizing information seasonal values (T_default) for each neighboring community for including in list.Figure 12 A is shown Table including neighbor cell list 150 comprising list the first row entry and secondary series entry of each neighboring community, The entry wherein mutually gone together corresponds to the default synchronous signal impulse trail seasonal values of associated neighboring community.

Figure 12 B show can with not only include neighboring community default synchronous signal impulse trail seasonal values but also The modes of update synchronous signal impulse trail seasonal values including neighboring community modifies neighbor cell list.In Figure 12 B institute In the specific specific implementation of the neighbor cell list 150' shown, third column are provided, this lists the adjacent small of associated row The update synchronous signal impulse trail seasonal values in area.

The neighbor cell list 150 of Figure 12 A and/or the neighbor cell list 150' of Figure 12 B can be phase between instruction frequency The table of adjacent cell list, or the table of instruction intra-frequency neighbor cells list.

Therefore, the neighbor cell list of the default synchronous signal impulse trail seasonal values including neighboring community can be letter It enables, the table of the neighbor cell list 150 of such as Figure 12 A or the neighbor cell list 150' of Figure 12 B, or can be dedicated signaling To particular wireless station 26-9A.

For the example embodiment and mode of Fig. 9, if the default that wireless terminal 26-9A cannot obtain neighboring community is same Signal pulse trail seasonal values are walked, then smallest synchronization property information cycle value can be used in wireless terminal 26-9, shows some It is 5 milliseconds in example specific implementation.

Therefore, for the example embodiment of Fig. 9 and mode, neighboring community can be configured with different default SSBSP values. There are two types of alternative scenarios for the scene of Fig. 9.In the first scenario, alternative C.l, the default SSBSP of neighboring community is in broadcast signaling And/or UE is indicated into the dedicated signaling of CONNECTED mode UE, or indicate in the broadcast signaling to IDLE mode UE To UE.As an example, the NR cell information between broadcasting frequency in NR-SIB information, for example, being similar in LTE system There is between instruction frequency the table of neighbor cell list and corresponding default SSBSP (if there is optionally feelings A.1 in SIB 5 Condition, it is also possible to indicate possible update SSBSP), UE is understood by the table and is defaulted in neighboring community using what between frequency SSBSP.It may include similar intra-frequency neighbor cells SSBSP information in relevant NR-SIB information.Such table information can also To include in the dedicated signaling to certain particular UEs.In the latter case, optionally C.2, if wireless terminal (UE) can not Understand neighboring community SSB information, then UE always uses minimum SSBSP (for example, 5ms) to detect SS.

It is non-limiting that Figure 10 shows the example representation that can be carried out or be executed by the Radio Access Interface 22-9 of Fig. 9 Movement or step.Acting 10-1 includes synchronization information generator 54, in the signal includes for relative to the same of neighboring community Walk the synchronizing information seasonal values of signal detection process.Movement 10-2 includes transferring signals to wireless end by air interface End.Fig. 9 shows the transmission of the default synchronous signal impulse trail periodic quantity of neighboring community in signal 142.

Figure 11 show can by the wireless terminal 26-9 of Fig. 9 carry out or execute example representation it is non-limiting movement or Step.Movement 11-1 includes that wireless communication is received from radio access network by air interface.Acting 11-2 includes attempting Synchronizing information seasonal values are obtained from wireless communication, for the synchronization signal detection process relative to neighboring community.Institute as above It states, the default synchronous signal impulse trail of neighboring community can be obtained from the signaling 142 that radio access node 22-9 is transmitted Seasonal values, the signaling can be the form of neighbor cell list.If wireless terminal 26-9 cannot obtain the silent of neighboring community Approval step signal pulse trail seasonal values, then wireless terminal 26-9 can be by the smallest known default synchronous signal impulse trail Seasonal values are used for the default synchronous signal impulse trail seasonal values of neighboring community.
