These UE or IoT equipment 110,112,114,116 or 118 can also be by non-juxtaposed anchoring.Non-juxtaposed deployment allows eNB and WiFi node Or other nodes are at separate device or component independent of one another and separated.UE/IoT equipment 110,112,114,116 or 118 can It is configured as operating based on the non-juxtaposed anchoring of the unlicensed multi-carrier operation between frequency of NB IoT.For licensed spectrum Narrow-band IoT can for example meet for be used for time-division multi-carrier polymerizing (TDMCA) operation carrier wave between position have it is more Close certain requirements (in connecting and frequency band).

For example, carrier wave can in the same channel, thus they can be it is in frequency band and in the frequency spectrum really adjoined, So that synchronization, frequency drift, timing behavior more or less can be adjoined to or reconcile between anchor carrier and extra carrier, Wherein UE communication can immediately begin to operation to load transfer, to transfer or effectively communicate.If carrier operation is based on load The combination of wave, then according to this principle, allows anchor carrier in licensed spectrum and allow non-anchor carrier in unlicensed frequency spectrum It may make the requirement of connecting property in this frequency band to lose or lose according to definition and TDMCA operated neither in same frequency frequency band In the frequency spectrum that does not also adjoin.

Embodiment herein can enable the non-juxtaposed anchoring of the unlicensed multi-carrier operation between frequency, to support NB The non-juxtaposed anchoring of the unlicensed multi-carrier operation non-contiguous between frequency of IoT.NB-IoT multi-carrier operation (multi- Carrier operation, MCO) it is not less than or equal to 20MGhz and NB-IoT by sum frequency span in one embodiment The synchronous constraint of one PRB main carrier.In this way, LTE channel 20MHz can be left and aloow the operation of IoT equipment Into in another frequency band, so that TDMCA operation is that non-frequency adjoins (non-frequency connecting/non-contiguous).In this way, two letters Road can be used, and IoT equipment 110,112,114,116 or 118 can be operated wherein based on TDMCA operation: anchored component carrier wave With additional anchored component carrier wave, they are nonsynchronous.

In some embodiments, these carrier waves can be in anchor carrier and additional non-anchor/unlicensed by separated synchronization On carrier wave.It is synchronous for example to be enabled in UL/DL authorization either without authorization, thus UE or IoT equipment for example start the time/ The specific resources of spectral band.

With reference to Fig. 2, a kind of example network is illustrated, which is configured as example enabling legacy network devices, the next generation The network equipment (network equipment based on 5G network), new radio (new radio, the NR) network equipment and be used for autonomous system Or the operation of the IoT network equipment of anchoring LTE system, these network equipments can be independent or in one or more networks In be communicatively coupled.These network equipments can be configured to communicate via communication protocol stack, which can be based on open source It interconnects (Open Source Interconnected, OSI) model and is defined between various layers and realize communication protocols The networking framework of view.Control can be transmitted to next layer from one layer, for example, since the application layer in a station or node, Bottom is proceeded to, next station is gone to by channel, and return up in hierarchical system.

Network system 200 is for traditional network (for example, the evolution package core (evolved in the LTE of left-hand side Packet core, EPC) 204) and the next-generation core 206 with 5G radio (for example, right-hand side based on include IoT The RAN 210 of 5G RAT including RAT) between potential intercommunication intercommunication architecture example.Each example individually or It can be component, the individual eNB WiFi node of eNB together, because of any one of RAN 208 and 210 operatively coupling It closes or including both EPC 204 and next-generation core 206.EPC 204 and next-generation core 106 can be connected respectively to belong to Subscriber services (home subscriber service, HSS) 202, such as via one or more interfaces (for example, arriving EPC 204 S6a interface or other interfaces).HSS 102 may include one or more databases for the network user, including subscribe Relevant information, for supporting processing of the network entity to communication session.For example, HSS 202 can to routing/roaming, authenticate, award Power, name/addressing parsing, position compliance etc. provide support.Network 200 may include one or several HSS 202, this takes Certainly in the number of mobile subscriber, the capacity of equipment, the tissue of network, etc..

Whether UE or IoT equipment 212,214,216 (for example, IoT equipment 110-118) signaling can be can determine based on equipment Communication stream is steered to EPC core 204 or next-generation core 206.The IoT network that EPC core 204 can enable anchoring is set Standby/system (or it is configured with the U-IoT anchoring net of the U-NB TDMCA operation as described herein with anchoring LTE carrier wave Network), and next-generation core 206 can enable U-IOT anchor network or the non-anchor IoT network as the independent IoT network equipment Equipment/system (or U-IoT separate network, have and allows all the components carrier wave as non-anchor non-LTE carrier wave as described herein U-NB TDMCA operation).

In left side, traditional UE 212 and the available RAN 208 based on LTE of 5G UE 214 are connected to LTE eNB, and Tradition UE 212 has a flow handled to EPC 204 by S1 interface in one example, and 5G UE 214 can have and pass through (one or more) NG2/NG3 interface is directed toward the communication of next-generation core 206, this can support to may include license auxiliary access (LAA), the infrastructure of enhanced LAA (eLAA), new radio, Internet of Things/machine to machine, IoT, MulteFire etc.. To which communication process can be different different IoT/UE, hence for a type of UE (such as IoT) or separately A type of UE (such as mobile device or other network equipments) a type of communication process can be enabled and equipment be by It is configured to independent (for example, U-IoT is independent) or is anchored (for example, U-IoT is anchored) network TDMCA operation.

The component of RAN 208 based on LTE can be used in the eNB of the RAN 208 based on LTE or evolved LTE or It is used as the eNB of the RAN 208, which is configurable to generate and manages cell coverage area/area 220, and is based on 5G Another eNB of the new RAT of RAT/ (NRAT)/MulteFire/U-IoT RAN 210 is controllable based on the small trivial of 5G/IoT standard Domain 222.Although being depicted as multiple overlay areas, this is an exemplary architecture and is not limited to the right side of system 200 Any one or more overlay areas shown in side and left side.

In in terms of the realization, the network equipment/system can be operated only on unlicensed frequency spectrum, without in licensed spectrum Anchoring, to pass through to as RAN's 210 to carry out communication signaling, such as via WiFi node dependent on unlicensed frequency spectrum ENB is juxtaposed or non-juxtaposed according to one or more various TDMCA operations.

With reference to Fig. 3, illustrate via the one or more network equipment (only unlicensed frequencies in standalone case shown in this article CA in spectrum) time division multiplexing carrier wave polymerization (TDMCA) operation 300 example (for example, be used for NB-IoT multi-carrier operation (MCO) the time division multiple acess access operation (TDMA) operated).For example, such as macro cell base station (102,104), small cell base station (106,108) or serve as relaying other IoT access points or IoT UE equipment (for example, UE equipment 110,112,114,116 or Etc 118) the network equipment can be based entirely on unlicensed carrier wave or based on license and unlicensed carrier wave according to different TDMCA It operates or operates related parameter with TDMCA and operated.

TDMCA operation 300 for example may include UL the and DL carrier wave utilized in the anchoring operation to IoT, or not have anchor Fixed carrier wave.Uplink carrier is with to upward arrow or towards upper arrow diagramming in Fig. 3, and downlink carrier is used Down arrow or the arrow diagramming under.For example, being illustrated as DL along the block of the top frequency line/axis expression carrier wave Expression carrier wave on carrier wave and bottom frequency line/axis is uplink carrier at the block of sub-carrier.

In addition, can be considered as supplement carrier wave at sub-carrier 302-306 with what oblique line or slash mark indicated, without appointing Those of what label expression composition carrier wave can be main carrier.It is operated based on TDMCA, IoT or the network equipment can be from frequency spectrums One at sub-carrier to another communication so that data payload is shifted.

Each group of DL carrier wave and associated UL carrier wave 302-306 can indicate that different TDMCA operates to support U-IoT to grasp Make.For example, TDMCA operation 302 is both including DL or including UL at sub-carrier.DL may include main carrier and supplement carrier wave at sub-carrier The two, and UL only includes main carrier, without supplementing UL carrier wave.For example, for TDMCA operation 304 in sub-carrier, UL It may include both main carrier and supplement carrier wave at sub-carrier, and DL only includes main carrier.

In another example, TDMCA operation 306 may comprise supplement carrier wave in both UL and DL.Carrier wave is supplemented non- In licensed spectrum and it is used in TDMCA anchoring mode.Alternatively possible operation mode is independent unlicensed operation.Scheming What is be not shown in 3 is that DL and UL carrier wave in non-licensed spectrum is not anchored.

Under all situations of TDMCA operation, independent or anchoring TDMCA operation may imply that operated in TDMCA to Not a possibility that few two carrier waves do not require main plot and time cell to be used simultaneously.Therefore TDMCA is unlike holding multi-carrier operation Capable mode is entangled with operation like that, the carrier wave first is that main plot and other carrier waves do not have institute in the latter in multi-carrier operation Be in the sense that information in need it is secondary, the information needed can by signaling indicate or can be scheduled.

With reference to Fig. 4, another example of the TDMCA operation for NB-IoT multi-carrier operation (MCO) operation is illustrated.As above It is described, such as macro cell base station (102,104), small cell base station (106,108) or the IoT UE equipment (example for serving as relaying 118) etc such as, UE equipment 110,112,114,116 or the network equipment can be based on license depicted herein and unlicensed carrier waves Related parameter manipulation is operated according to different TDMCA operations or with TDMCA.

In one example, TDMCA operation 400 shows anchoring TDMCA operation, and one of carrier wave can be license and carry Wave 402, another carrier wave can be unlicensed carrier wave 404.Here, main carrier 402 can be license carrier wave, be anchored as license, And it supplements carrier wave 404 and can be unlicensed carrier wave.Therefore TDMCA that UL supplement carrier wave 404 is used as being anchored (for example, TDMA) the supplement carrier wave operated.

In other examples, TDMCA operation can also unlicensed frequency spectrum be used as supplement downlink when be anchored and It allows license carrier wave in UL as main carrier and unlicensed carrier wave 404 is as supplement UL carrier wave.Alternatively or extraly, non- Licensed spectrum can be used for both DL and UL, as supplement carrier wave or as main carrier.

For example, the anchoring scheme in TDMCA operation 400 can be in the unlicensed frequency chunks of DL and UL when different on duplexing gap It is activated.Duplexing gap for example can be specific frequency sets or range, and uplink is above and downlink exists To prevent from interfering under it.One duplexing gap can be in a frequency sets, and another duplex is in another frequency sets.For example, The top (or upper range) of 600MHz license can be the 5MHz for uplink for allowing mobile device upload information, and bottom Portion's (or bottom range) can be the 5MHz in the 600MHz range for allowing information to download.It can be between lower range and upper range The duplexing gap of about 11MHz remains sky to serve as the protection band between uplink and downlink so that they exempt from It is interfered.It can also be envisaged that other examples.

In one example, these can be used (for example, as shown in Figure 3), because of carrier wave at sub-carrier by time-division mutual exclusion Can be it is one or another kind of (for example, license/it is unlicensed, or master/supplement) and independently of these carrier waves whether together Step.In the top line for DL carrier wave, they for example may be synchronized, for unlicensed not usually in this way, with Fig. 4 License situation it is opposite.In this way, example TDMCA operation and associated carrier wave are applicable to two kinds of carrier waves, (main carrier and supplement are carried Wave), all it is unlicensed or is all license, so that they is ideally sufficiently synchronous and possibly even in level side Along frequency spectrum it is upwards and abuts one another, and gap that is very close to each other therebetween or not can be changed.However TDMCA is operated 400 present non-contiguous property between two carrier waves in UL in contrast, and carrier wave involved in TDMA in gap or Person is also possible to variation among frequency bands, without in identical frequency band or be adjoined to, be close to or have therebetween each other Unified gap.

In another example, DL and UL non-anchor carrier can be used independently of each other in time and discharge or independent Ground releases coupling.In this way, above-mentioned example TDMCA operation 300 or 400 can be according to the further embodiment being also described herein with additional Synchronize further using license, unlicensed carrier wave perhaps the two or they also can be used in connecting operation in, at two kinds It is license or unlicensed in situation.

With reference to Fig. 6, illustrate according to one or more aspects/embodiment here for simultaneously operating or process TDMCA scheme 600.For example, two carrier waves 606,608 can belong to different frequency bands (TDMCA between frequency band) (for example, frequency band 610) or The different range of frequency band.

In various embodiments, two carrier waves 606,608 can belong to same frequency band (TDMCA in frequency band).At one or In multiple preceding embodiments, ideal backhaul is considered, and in an individual embodiment, be that the method for TDMCA proposition can be towards Time division multiplexing synchronizes the extension of dual connectivity TDMCA (DC TDMCA) process, and wherein UE or IoT equipment is directly logical between each other Letter realizes round-trip delay between several milliseconds of BS.Many network vendors point out that time unifying error is more than up to several milliseconds of limit Degree, and this delay can be corrected/be reduced to this TDMCA operation with synchronizing process of embodiment.

Any set group that carrier wave 606 or 608 can be considered as PRB in one example or group are (for U-NB IOT system System is 1PRB, is 6PRB for eMTC or is greater than 6PRB for FeMTC).In addition, in general embodiments, operation when Domain carrier wave polymerize principle can be in N_CA difference carrier wave (C₁,…C_NC) between be applicable in, wherein in one embodiment at least one carry Wave can be located in licensed spectrum (for example, being 610,624 respectively for DL or UL), and another carrier wave exists respectively for DL or UL In unlicensed band 608 or 622, and all executable TDMCA operation of carrier wave all in another different embodiments, 602/604 (for example, at least two) can be in unlicensed frequency spectrum 608/622 or other unlicensed ranges (standalone case).

It can be license at sub-carrier 606 and 620 in each frequency band 610,624, and carrier wave 608,622 can be with right and wrong Licensed band.Fig. 6 further illustrates supplement DL, means in DL operation using unlicensed band.This frame can open It is disposed with U-NB IoT, thus all utilizes licensed spectrum in DL and in UL in left side, while for example in LTE channel 610 or 624 Inside also utilize this licensed spectrum.In general, another carrier wave (for example, 608,622) can be utilized to be close in same frequency spectrum 610 or Adjoin beside carrier wave 610,624 in 624 or therewith.However, another frequency band or frequency spectrum or channel that do not adjoin here can quilts Using a part operated as TDMCA, without first understanding that the Physical Synchronization in the part DL, frequency shift (FS) or time are inclined It moves.

In one embodiment, switching period (for example, 720 of Fig. 7,722) can also be used in synchronous phase, can It is non-between half second to 1.5 seconds or some other times, to need in the switching of switching period 720 and to be then synchronized at this time Permit carrier wave, and then switch again in the switching period 722 and be synchronized to license carrier wave, this is shown as example in Fig. 7.

Fig. 6, which is shown, to be for example transferred to flow load in unlicensed carrier wave Shi Dangcong licensed band 610 when being switched to Anchor carrier 606,620 is synchronized to ideal situation when non-anchor carrier 608,622 respectively.In contrast, Fig. 7 show when The pause utilized in domain as switching slot 720,722, so as to for example from license carrier wave 702 be tuned to unlicensed carrier wave 706, 708 or to license carrier wave 704, it is synchronous and operate on it.In addition, synchronize can also occur again every now and then or Periodically occur, in response to obtaining/receive additional system information (for example, MIB/SIB or other data), or in response to Other reasons, IoT equipment can return to licensed spectrum (for example, again as carrier wave 704 or 702), or waits or return to Licensed spectrum 710 and subsynchronous again in another switching period 722.Additionally or alternatively, more than two carrier waves 702 or 706, multiple carrier waves can also be utilized from 1 to N in license or unlicensed band, wherein unlicensed and licensed band is in UL and DL In, such as only in DL or only in UL.

In this way, TDMCA operation here can simplify and shorten same and predicting the operation on license carrier wave 702/704 These switching periods 720,722 of step, the smaller permission of gap 720,722 is of short duration to slip into unlicensed carrier wave 730, then By really be tuned to other frequencies it is fully synchronized to execute really, and this is also to have synchronous gap 720,722 The proposal made in TDMCA operation.This for example can avoid that UE/IoT equipment is required to have the normal burden for supporting carrier wave, and wherein UE has There are radio frequency (RF) and base band (BB) ability by multiple carrier waves while receiving signal.

With wherein UE there is RF and BB ability to receive letter simultaneously at sub-carrier by several in order to avoid requiring UE to have Number normal carrier wave support associated burden, it can be envisaged that various further embodiments.

According to embodiment, the IoT/UE/ network equipment can be at any time in single carrier wave C_jIt is middle to operate and be switched to load Wave C_m.These embodiments or aspect according to this operation can be related to DL or UL and change.

In embodiment relevant to DL, for example, specific and scheduled mode can be by eNB for example via RRC signaling or Jie Matter access control (media access control, MAC) control element (control element, CE) is with semi-static or half Continue signaling method to notify.In one embodiment, eNB (for example, the 102 of Fig. 1,104,106 or 108) can be in main plot 124, integrated pattern is indicated on 126.In another example, eNB (for example, the 102 of Fig. 1,104,106 or 108) can be indicated only each The first step (or preceding " N " step) at sequence or switch mode between sub-carrier is planted, and subsequent step can be believed via control It number is indicated in the interviewed carrier wave of N-x.Wherein N and x for example can be the intensified learning (reinforcement depending on needing Learning, RL) amount predetermined number, or fixed number, such as can correspond to one or more resources or carrier wave.

In another embodiment, these sequence patterns of the operation on carrier wave here can be notified in a dynamic fashion by eNB, Rather than semi-continuous or cycle time.For example, down link control information (downlink control information, DCI it) can be carried by control channel, therefore these control channels, which can be only positioned on main carrier, (and utilizes background in traditional LTE In defined cross-carrier scheduling concepts) or be located at any other carrier wave in.According to this embodiment, the control in carrier wave K Channel processed can indicate that the position of next carrier wave and wherein find related data, wherein can be positive integer.In this situation In, N can be equal to 1 and x equal to 1.

In another embodiment, multi-carrier operation can be based on UE/IoT feedback selection.According to the method, UE/IoT can be via Feedback indicates which of multicarrier can correspond to best channel condition (it is assumed that discovery reference signal (reference Signal, RS) in the presence of the measurement that calculates).According to a specific example, UE/IoT can indicate one via bitmap A preferred carrier wave of group " M ", eNB then can indicate which carrier wave used according to the method illustrated above based on eNB.UE is subsequent It can be used one or more measurements to identify " M " a best carrier.Measurement for example may include that (it can be surveyed channel reciprocity based on DL Amount), interference measurement, one or more of path loss (its in the case where non-juxtaposed deployment can different) or these Any combination.

In embodiment related with UL, eNB 102-108 can be selected by the instruction to UE/IoT equipment 110-118 Carrier wave to be used.ENB 102-108 can for example indicate which carrier wave should be by via the use to downlink authorization It is accessed in the case where beginning in unlicensed frequency spectrum via the agreement of similar LBT for the UE/IoT equipment 110-118 in NB Channel distributes access channel according to eNB in licensed spectrum.
