Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, below by specific embodiment knot It closes attached drawing and optional be described in detail is made to the embodiment of the present invention.It should be appreciated that specific embodiment described herein is only used to It explains the present invention, is not intended to limit the present invention.

The micro- of scheduling is still exempted from the mini-slot polymerization (Mini-slotbased aggregation) of either dynamic dispatching Time slot repeats for (Mini-slot based repetitions), when the transmission direction of transmission opportunity and frame structure is touched When hitting, which loses or retains, and how to determine the resource distribution of repetition transmission opportunity.And because with son The transmission direction of frame structure is collided, and base station may delay the multiple transmission opportunities of configuration, or even configure when on different time-gap, as Listed hereinbefore, 5G system supports the business harsher to delay requirement, how to guarantee that terminal completes uplink in a fixed response time It is also all problem in need of consideration that data, which are repeated several times and send,.In addition, it is noted that being passed in various embodiments of the present invention Defeated chance and the transmission direction of frame structure collide, and the transmission direction of also referred to as transmission opportunity and frame structure is rushed It is prominent；Upstream data can specifically include TB, PUSCH etc., and self terminal is sent to the data of base station, in various embodiments of the present invention Upstream data can be considered as.

First embodiment

A kind of repetitive transmission method is present embodiments provided, referring to FIG. 1, the repetitive transmission method includes:

S101, each transmission opportunity TO for determining the upstream data transmitted to repetition；

S102, wait repeat transmission upstream data all TO in, at least one TO not with the frame structure of configuration transmit When direction conflicts, then the repetition transmission of upstream data is carried out on TO.

In some embodiments, the repetition that upstream data is carried out on TO, which is transmitted, may include:

The earliest TO of time domain that the upstream data for repeating transmission never conflicts with the frame structure transmission direction of configuration is started to pass It is defeated.The transmission direction of the frame structure of configuration may include the direction F of uplink U, downlink D and flexible configuration；The present invention is respectively implemented The upstream data repeatedly transmitted in example, the matched transmission direction of upstream data institute should be U, that is to say, that when frame structure When transmission direction is U, the transmission opportunity TO of upstream data does not just conflict therewith, and if the transmission direction of frame structure is D, With regard to conflicting therewith certainly；If the transmission direction of frame structure is F, then determined according to current transmission situation.

In some embodiments, by repeat transmission upstream data never conflict with the frame structure transmission direction of configuration when The earliest TO in domain starts transmission

By in the upstream data for repeating transmission, redundancy versions index the upper of RV (Redundancy version) index=0 Row data carry out repeating transmission since the earliest TO of time domain；In general, the TO of upstream data can be transmitted earliest, it is corresponding RV index should be 0, this is the agreement obeyed between base station and terminal, from its rule.The upper of transmission is repeated when same In row data, when the number that RV index is 0 includes two or is above, the first RV index that can be subject to is 0, or Any one RV index is subject to 0.

Or, upstream data corresponding with earliest TO time domain is since the earliest TO of time domain by the upstream data for repeating transmission It repeats to transmit.Other than the reference of RV=0, it can also be started with the earliest TO of the time domain not clashed, the TO is corresponding Upstream data as starting transmitted；In this case, the RV index of the upstream data original transmission is then not necessarily 0。

In some embodiments, the earliest TO of time domain not conflicted with the frame structure transmission direction of configuration includes:

In each TO, the earliest TO of time domain that all time-domain symbols do not conflict with the frame structure transmission direction of configuration；This is table Showing, the earliest TO of the time domain is time-domain symbol all in the TO, do not conflict with the transmission direction of frame structure, if, it should It include 2 time-domain symbols in TO, then the two time-domain symbols do not conflict with the transmission direction of the frame structure of configuration, such as It says, the transmission direction of corresponding frame structure should be UU or FU.

Or, in each TO, the earliest TO of time domain that at least one time-domain symbol does not conflict with the frame structure transmission direction of configuration.This When the earliest TO of time domain, then it represents that, as long as there is the time-domain symbol not conflicted, then just in time-domain symbol in the TO It is believed that the TO is the earliest TO of time domain not conflicted.

In some embodiments, frame structure can be obtained from least one of following manner:

Detect DCI (Downlink Control Information, Downlink Control Information) time slot format instructions field；

The time slot format for detecting RRC (Radio Resource Control, wireless heterogeneous networks) configuration indicates order.

In some embodiments, the repetition transmission that upstream data is carried out on TO may include: in TO, at least one when When domain symbol does not conflict with frame structure transmission direction, then rate-matched is done to the time-domain symbol in TO, not conflicted.Due in the TO At least one time-domain symbol does not conflict with frame structure transmission direction, and other symbols then potentially conflicting, in order to guarantee upper line number According to normal transmission, then rate-matched is carried out to the time-domain symbol that does not clash in TO.

In some embodiments, doing rate-matched to the time-domain symbol in TO, not conflicted may include:

By in MCS (Modulation and Coding Scheme, modulation and coding strategy) parameter of RRC configuration Order of modulation is constant, and obtains new code rate according to available Resource Calculation remaining in TO, executes rate-matched according to new code rate； Or,

New order of modulation and code rate is calculated and carries out uplink, and the modulation order information being calculated is reported To base station, code rate then is calculated according to available resources remaining in order of modulation and TO；Or,

New order of modulation is calculated according to available resources, and uplink is directly transmitted according to code rate and new order of modulation Data.

In some embodiments, the repetition that upstream data is carried out on TO is transmitted

The service condition of TO is indicated by detection DCI.Wherein, DCI be base station side it is newly-increased repeat to pass about upstream data Defeated detection means, terminal can be by detecting the DCI, to determine the service condition of current TO.In some embodiments, pass through Detection DCI indicates that the service condition of TO includes:

By detecting DCI, the relevant parameter that uplink exempts from scheduled transmission configuration is obtained；

The configured transmission of the TO of instruction is adjusted, and carries out the repetition transmission of upstream data based on TO adjusted.

In some embodiments, the relevant parameter that uplink exempts from scheduled transmission configuration may include at least one following:

Time-domain resource,

Frequency domain resource,

The iterative transfer times K of RRC configuration,

TO index,

MCS,

The entry-into-force time of parameter reconfiguration/number.

In some embodiments, the repetition transmission that upstream data is carried out on TO can also include: by time-domain symbol and frame The TO of structural transmission direction conflict is not counted in the iterative transfer times of upstream data, and continues upper line number on the TO for delay configuration According to repetition transmission.This is to indicate, upstream data is not transmitted on the TO of conflict, is directly configured not in the time-domain symbol delayed The TO of conflict is transmitted.

In some embodiments, the repetition transmission of upstream data is carried out on TO further include: according to the redundancy TO of pre-configuration, Upstream data corresponding to the TO that time-domain symbol is conflicted with frame structure transmission direction is delayed and carries out repeating biography on redundancy TO It is defeated.This is to indicate, when base station is that terminal configures TO, directly adds certain redundant configuration with number of repetition needed for terminal Amount, Lai Shixian uplink signal repeat being adjusted flexibly for transmission, for example, base station is matched when the iterative transfer times needed for terminal are 4 times Setting to the TO quantity of terminal can be then 5, in this way in preceding 4 TO, when there is a conflict, still can pass through redundancy TO gathers together enough 4 and can be repeated to send upstream data with TO.

In some embodiments, on TO carry out upstream data repetition transmission further include: according to pre-configuration not with frame The TO of structural transmission direction conflict carries out upstream data by TO to repeat transmission.This is to indicate, when configuring TO just directly with The mode of pre-configuration skips those time-domain symbols that can conflict with frame structure transmission direction, and directly in the time domain symbol not conflicted It is configured on number.

In some embodiments, further include acquisition time window, upstream data is sent by the TO that time window judgement is delayed Situation.Setting time window is in order to guarantee time delay, since in 5G business, URLLC (the reliable ultralow time delay communication of superelevation) is to time delay It is required that it is very high, prolong backward in case of the corresponding upstream data of TO of conflict, delay requirement may be exceeded, so as to cause Therefore time window is arranged to monitor the number that upstream data repeats transmission, if beyond expection in the problem of URLLC business.

In some embodiments, time window and the sum of terminal, base station processing processing time are less than or equal to preset threshold.This is pre- If threshold value, the different from according to the delay requirement of different business, such as, for URLLC business, preset threshold it is big Small can be 1ms.Certainly, the present embodiment only enumerates a possible example to the preset threshold, and those skilled in the art answer This knows that the preset threshold can be the reasonable duration in corresponding type of service, and the present embodiment is simultaneously not limited thereof.

In some embodiments, judge that the case where TO delayed sends upstream data includes: by time window

By in the upstream data for repeating transmission, transmission starts to the duration of the TO delayed to be compared with time window for the first time Right, when duration is less than or equal to time window, the TO delayed then can be used for sending upstream data.

Alternatively, detecting last of the place DCI control resource collection CORESET in the upstream data for repeating transmission The duration of a symbol to the TO delayed are compared with time window, when duration is less than or equal to time window, delay TO then can be used for sending upstream data.

In some embodiments, the repetition that upstream data is carried out on TO is transmitted

According to the instruction of base station, the practical number of repetition of upstream data is determined.It is then the direct instruction for receiving base station at this time, To determine the number of repetition transmission, such as base station according to the time delay of upstream data, determine that the number for repeating transmission is 2 times, then Terminal side repeats transmission upstream data twice then according to the instruction of base station on the TO not clashed, even if the number of setting It is 4 times, still carries out 2 times indicated by base station iterative transfer times.

In some embodiments, according to the instruction of base station, determine that the practical number of repetition of upstream data may include:

According to time delay target value, judge that can each TO send upstream data, and determine practical number of repetition.

5th embodiment

Present embodiments provide a kind of repetitive transmission method.A kind of simple effective method is exactly that gNB and UE arranges uplink Exempt to dispatch certain repetition and dynamic SFI in UL grant-free transmission to clash, in the secondary repetition time domain Place TO carries out rate-matched, re-starts rate-matched (this time according to the secondary available symbol of repetition TO The available symbol definition of repetition TO is and the symbol that does not have transmission direction to conflict in dynamic SFI), due to lacking DCI letter Relevant parameter (such as adjusting order and code rate) after enabling indicated speed match, needs clear one to execute speed between gNB and UE The matched criterion of rate understands differently cause to avoid base station side and user side, causes decoding error.Rate is executed between gNB and UE At least one for example following selection modes of the criterion matched:

(1) the repetitions transmission TO that uplink exempts from that all in scheduled transmission and dynamic SFI is clashed are carried out rate-matched, speed The matched principle of rate is to keep the order of modulation in RRC configuration MCS parameter constant, and user and base station are all according to certain to collide Remaining available Resource Calculation obtains new code rate in secondary repetition transmission, and user executes rate-matched according to new code rate.

(2) the repetitions transmission TO that uplink exempts from that all in scheduled transmission and dynamic SFI is clashed are carried out rate-matched, speed The matched principle of rate is the order of modulation and code rate for allowing UE to change the MCS parameter that RRC is configured, and UE is according to being calculated new tune Order and code rate processed carry out uplink, while the modulation order information being calculated is reported to base station by user, base station according to The order of modulation that UE is reported and remaining available resources in the secondary TO are calculated code rate and carry out data demodulation.

Wherein, the mode of reporting of user modulation order information may include following two:

Mode one: PUCCH channel is utilized.When base station configures grant-free PUSCH resource by RRC or DCI, Also PUCCH resource can be configured.So user adjust MCS after, the TO it is corresponding exempt from dispatch transmitted over resources data, in PUCCH Upper transmission MCS information.Further, RRC configures Nbit MCS corresponding relationship, such as 2bit.QPSK is indicated with 01.So work as terminal When adjustment MCS is QPSK, PUCCH carries 01 this 2bit, means that QPSK.Utilize the resource notification exempted from except scheduling resource.

Mode two: PUSCH channel is utilized.Base station and terminal arrange which handy RB index in advance sends MCS, and about Set the order of modulation and code rate for sending MCS using fixation.Such as with low index RB and QPSK+1/2 code rate.For example it distributes to The frequency domain resource of PUSCH is RB1~RB10, then sending MCS information with RB1.So base station, which is known, has part resource to touch with SFI It hits, RB1 will be solved first first to obtain MCS, and then decode demodulation PUSCH data information.

(3) the repetitions transmission TO that uplink exempts from that all in scheduled transmission and dynamic SFI is clashed are carried out rate-matched, speed The matched principle of rate is to keep the code rate of the MCS parameter of RRC configuration constant, and UE and base station are all according to the current secondary repetition Remaining available Resource Calculation obtains new order of modulation in TO, and user carries out upstream data according to code rate and new order of modulation Transmission, base station carry out data demodulation according to the code rate and new order of modulation.I.e. terminal does not report new order of modulation.

Sixth embodiment

Present embodiments provide a kind of repetitive transmission method.In the present embodiment, a new DCI is introduced to indicate how Use the resource.The function of new DCI is some parameters for resetting UL and exempting from scheduled transmission configuration, and UE, which receives the DCI and only changes, to be referred to The configured transmission for showing TO, for the TO not indicated, UE continues to transmit according further to original mode (being semi-statically configured).New DCI Need with a new RNTI scrambling, for distinguish the DCI and other for the DCI of schedule data transmission and other be used to swash Living or deactivated DCI, the parameter that new DCI resetting UL exempts from scheduled transmission configuration include at least one of following parameter:

Time-domain resource,

Frequency domain resource,

The iterative transfer times K of RRC configuration,

TO index,

MCS,

The entry-into-force time (number) of parameter reconfiguration,

Specifically, based on new DCI, to the instruction of TO can in the following manner in any progress:

(1) the iterative transfer times K for the DCI resetting RRC configuration not introduced newly, UE is given according to current frame structure in base station Indicate that UL exempts from scheduled transmission and frame structure collides the index of TO, and time-frequency domain resources and MCS in corresponding collision TO, UE is according to information is indicated in DCI, information transmits corresponding TO as indicated.The parameter entry-into-force time of DCI resetting can be by 1bit indicates that the parameter of 0 expression DCI resetting only comes into force primary (for this resetting), and 1 indicates the parameter of DCI resetting It comes into force repeatedly, until base station is reconfigured to UE, UL exempts from the resource of scheduling or SFI changes again.

Optionally, it is contemplated that the expense of frequency domain resource instruction, the DCI can not include frequency domain resource instructions field, that is, Frequency domain resource is not reset, the size of frequency domain resource is also according to the configuration before DCI resetting.

(2) need to indicate that new repetition passes in the iterative transfer times K, DCI of the DCI resetting RRC configuration for allowing newly to introduce The defeated number K and corresponding TO index of corresponding the number of transmissions, and indicate the time-frequency domain resources and MCS of corresponding TO index, UE is according to information is indicated in DCI, information transmits corresponding TO as indicated.The parameter entry-into-force time of DCI resetting can be by 1bit indicates that the parameter of 0 expression DCI resetting only comes into force primary (for this resetting), and 1 indicates the parameter of DCI resetting It comes into force repeatedly, until base station is reconfigured to UE, UL exempts from the resource of scheduling or SFI changes again.

7th embodiment

Present embodiments provide a kind of repetitive transmission method.In UL grant-free transmission, in order to improve reliability, gNB Transmission can be repeated several times to a business packet configuration, UE certain repetition and dynamic SFI when repeating to transmit collides, As long as in certain repetition TO and not all symbol is all clashed with dynamic SFI, then UE does not lose this time Repetition transmission, only destroys the symbol accordingly collided, is transmitted without the data on the symbol of collision.

Further, base station this exempt from the scheduled transmission period where the last one TO behind time-domain position symbol or when It goes to retransmit the UL data destroyed by collision using available resource in gap.

8th embodiment

Present embodiments provide a kind of repetitive transmission method.As long as when there is a symbol in the time-domain position where some TO Transmission direction and semi-static SFI collide, then the TO is just not counted in number of repetition, base station, which can be delayed, configures the TO.

But to delay requirement harsher business such as URLLC, it may require that TB has been sent from all repetitions are reached No more than 1ms time delay.For delaying the TO of transmission, terminal how under the premise of being no more than time delay completes that transmission is repeated several times, Possible mode is as follows:

Base station is gone to judge actual transmissions TO and number according to time window T by RRC signaling configurator timing window T, terminal.

Optionally, as shown in figure 9, T size refers to that terminal detects the last one of dynamic dispatching DCI place CORESET Symbol sends the time interval t2 of time domain persistence length to the corresponding data of the practical number of repetition of maximum that can be supported.Wherein, t2 It is no more than such as 1ms delay requirement with the sum of terminal, base station processing time t1+t3.

Further, terminal judges that the TO#n duration is less than or equal to t2, then terminal can be sent on TO#n Row data.When terminal judges that the TO#n duration is greater than t2, then terminal cannot just send upstream data on TO#n.

Optionally, TO#n, n can be any one or more in [1, K].Wherein K is high-rise configuration or DCI notice Number of repetition.

As Fig. 9 signal provides the decomposition for each period that 1ms time delay includes.Wherein the time delay of t1+t2+t3 is 1ms.t1 It is the terminal processes upstream data+subframe alignment+base station transmission SR+ processing this section of total time of SR；T2 is that terminal detects the place DCI CORESET last symbol+terminal demodulation DCI prepares the temporal duration that PUSCH+ repeats transmission PUSCH, this section is total Time is t2；T3 is base station demodulation PUSCH data, judges to be this section of total time of ACK/NACK.

So for the aggregation transfer PUSCH of DCI scheduling, RRC or DCI notice repeat transmission times K=4.Such as Shown in Figure 10, the time-domain position of four TO is not distributed in the same slot.Because of the biography of symbol #0 and #1 on slot n+1 Defeated direction is D, is configured on symbol #2 and #3 so TO#4 is delayed.

Time delay schematic diagram as shown in connection with fig. 9, terminal are judged according to t2 time size if sent on Figure 10 TO#4 PUSCH, then can be more than t2.So the 4th that terminal will not send PUSCH on TO#4 repeats.

It is also possible to terminal to judge if sending PUSCH on Figure 10 TO#4 does not exceed t2 thresholding, so terminal meeting The 4th that PUSCH is sent on TO#4 repeats.

It is assumed that terminal finally judges to repeat to send 3 PUSCH, so " the maximum reality that can be supported expressed above The corresponding data of number of repetition send time domain persistence length " just refer to that being sent to TO#3 for the first time from TO#1 terminates the reality for repeating to send 3 repetitions in border send the time domain persistence length of data.

9th embodiment

Exempt from scheduling for uplink to repeat in transmission PUSCH technology, as shown in figure 11, T size refers to from terminal to be transmitted for the first time PUSCH starts to the corresponding data of the practical number of repetition of maximum that can be supported to send the time interval t2 of time domain persistence length.Its In, the sum of t2 and terminal, base station processing time t1+t3 are no more than such as 1ms delay requirement.

As Figure 11 signal provides the decomposition for each period that 1ms time delay includes.Wherein the time delay of t1+t2+t3 is 1ms. T1 is terminal processes upstream data+subframe alignment time；T2 is that terminal repeats to send the temporal duration of PUSCH；T3 is Base station demodulates PUSCH data, judgement is this section of total time of ACK/NACK.

So for the repetition transmission PUSCH for exempting from scheduling, RRC or DCI notice repeat transmission times K=4.Such as figure Shown in 12, the time-domain position of four TO is not distributed in the same slot.Because of dynamic SFI designated symbol #0 on slot n+1 Transmission direction with #1 is D and F, is configured on symbol #2 and #3 so TO#3 is delayed, and TO#4, which is delayed, is configured to symbol #4 and # On 5.

The time delay schematic diagram in conjunction with shown in Figure 11, terminal are judged according to t2 time size if in Figure 12 TO#3 and TO# PUSCH is sent on 4, then can be more than t2.So the 4th that terminal will not send PUSCH on TO#3 and TO#4 repeats.

It is also possible to terminal to judge if sending PUSCH on Figure 12 TO#3 and TO#4 does not exceed t2 thresholding, so The 4th that terminal can send PUSCH on TO#3 and TO#4 repeats.

It is assumed that terminal finally judges to repeat to send 2 PUSCH, so " the maximum reality that can be supported expressed above The corresponding data of number of repetition send time domain persistence length " just refer to that being sent to TO#2 for the first time from TO#1 terminates the reality for repeating to send 2 repetitions in border send the time domain persistence length of data.

Tenth embodiment

Present embodiments provide a kind of repetitive transmission method.For delaying the TO of transmission, how terminal is being no more than time delay Under the premise of, it completes that transmission is repeated several times, possible mode is as follows:

Base station notifies to give terminal practical number of repetition.

Base station does not notify to terminal time window t2 size.When base station oneself is no more than such as 1ms according to the t1+t2+t3 time Prolong target value, judges that TO#n cannot be used to send PUSCH data, otherwise can be more than t2 thresholding, so that base station is notified by DCI Give terminal practical number of repetition.

Optionally, base station notifies to give terminal practical number of repetition by DCI.

Optionally, TO#n, n can be any one or more in [1, K].Wherein K is the number of repetition of high-rise configuration.

11st embodiment
