Alternatively, when including time domain instructions field in the Downlink Control Information DCI format used in the PDCCH, according to using the The SPS PDSCH that scheduling timing indicated by time domain instructions field in DCI format used in the scrambled PDCCH of one RNTI determines Transmission opportunity, and indicated by the time domain instructions field used in the PDCCH that is activated according to instruction SPS PDSCH in DCI format Scheduling timing determine SPS PDSCH transmission opportunity it is identical.

It should be noted that scheduling timing indicated by time domain instructions field in the embodiment of the present application in DCI format refers to Number of time slots between PDCCH and scheduled PDSCH.For example, when PDCCH is when time slot n is sent, it can be with time slot scheduling n+K0 Middle carry out PDSCH transmission, value when wherein K0 belongs to a scheduling for being pre-configured with or defining in ordered sets, by PDCCH In time domain instructions field instruction.

Method 1-2, include in the DCI format used in the PDCCH be used to indicate PDSCH to HARQ-ACK timing it is anti- When presenting timing instructions field, using the feedback timing instructions field in DCI format used in the first scrambled PDCCH of RNTI, with finger Show that content indicated by the feedback timing instructions field in DCI format used in the PDCCH of SPS PDSCH activation is identical.

It should be noted that feedback timing indicated by feedback timing instructions field in the embodiment of the present application in DCI format Refer to the number of time slots between the HARQ-ACK transmission of PDSCH and PDSCH.For example, when PDSCH is in time slot n, can when Carry out changing the HARQ-ACK feedback of PDSCH, ordered sets when wherein K1 belongs to a feedback for being pre-configured with or defining in gap n+K1 In one value, by PDCCH feedback timing instructions field indicate.

Specifically, the above method may be used singly or in combin；The Downlink Control Information used in the PDCCH When the feedback timing instructions field of the timing of the time domain instructions field or PDSCH to HARQ-ACK that include in DCI format:

For example, if instruction updates the feedback of the timing not comprising PDSCH to HARQ-ACK in the PDCCH of SPS and activation SPS Timing instructions field (i.e. HARQ-ACK timing instructions field) and include time domain instructions field, then using being pre-configured with or arrange same One HARQ-ACK timing, so that HARQ-ACK timing corresponding to the PDCCH of instruction SPS update and activation is inherently It is identical, in order to guarantee " according to the time-domain position of the HARQ-ACK for the SPS PDSCH for using the scrambled PDCCH of the first RNTI to determine (such as position slot, can also be specific character position certainly, similarly hereinafter), with the PDCCH according to instruction SPS PDSCH activation The time-domain position of the HARQ-ACK of determining SPS PDSCH is identical ", then only need guarantee according to use the first RNTI scramble In PDCCH time domain instructions field instruction scheduling timing determine PDSCH time-domain position, with according to instruction SPS PDSCH The time-domain position for the PDSCH that the scheduling timing of time domain instructions field instruction in the PDCCH of activation is determined is identical.For example, can be with Identical scheduling timing and identical PDCCH transmission location are used when so that updating SPS and activation SPS；Alternatively, to update Using different PDCCH transmission locations and different scheduling timing when SPS and activation SPS, but dispatches timing and determined Transmission PDSCH where time-domain position it is identical, i.e., guarantee SPS update after and SPS activate when transmission opportunity it is identical, to press Identical time domain feedback position (such as same slot) is determined according to identical HARQ-ACK timing, guarantees identical time domain Feedback position.

If indicating, updating SPS and instruction activates in the PDCCH of SPS and does not include comprising HARQ-ACK timing instructions field When time domain instructions field, then the preconfigured same scheduling timing is used, i.e. instruction SPS updates and the PDCCH of activation institute is right The scheduling timing answered is inherently identical, if instruction SPS updates at this time and the PDCCH of activation is sent at the time of identical, and really The fixed same PDSCH transmission moment, it is identical with the SPS transmission opportunity of activation to determine that instruction SPS is updated；In order to guarantee " root According to the time-domain position of the HARQ-ACK for the SPS PDSCH for using the scrambled PDCCH of the first RNTI to determine, and according to instruction SPS The time-domain position of the HARQ-ACK for the SPS PDSCH that the PDCCH of PDSCH activation is determined is identical ", it also needs to guarantee to indicate at this time SPS update is identical with the HARQ-ACK timing of activation, that is, guarantees identical feedback position；Alternatively, if instruction SPS updates It is sent at different times with the PDCCH of activation, it is determined that instruction SPS updates and the PDSCH of activation is transmitted in different moments, is Guarantee " according to the time-domain position of the HARQ-ACK for the SPS PDSCH for using the scrambled PDCCH of the first RNTI to determine, with basis Indicate that the time-domain position of the HARQ-ACK for the SPS PDSCH that the PDCCH of SPS PDSCH activation is determined is identical ", it also needs to protect at this time Card instruction SPS updates the HARQ-ACK timing difference with activation, to guarantee identical feedback position.

If indicating to update in the PDCCH of SPS and instruction activation SPS and both not including HARQ-ACK timing instructions field or not When comprising time domain instructions field, then the preconfigured same scheduling timing and same HARQ-ACK timing is used, is only needed Guarantee to indicate that SPS updates and the PDCCH of activation is sent at the time of identical；At this time if it is determined that PDSCH is when same Transmission is carved, then it is identical with transmission opportunity when activation in update to further determined SPS, to ensure that identical feedback bit It sets.

Method 2,

It include time domain instructions field and the timing for being used to indicate PDSCH to HARQ-ACK in the DCI format used in the PDCCH Feedback timing instructions field when, according to use in DCI format used in the first scrambled PDCCH of RNTI feedback timing instruction Scheduling timing indicated by domain and time domain instructions field determine SPS PDSCH HARQ-ACK time-domain position, with according to Feedback timing instructions field and time domain instructions field in the DCI format used in the PDCCH of instruction SPS PDSCH activation is signified The time-domain position of the HARQ-ACK for the SPS PDSCH that the scheduling timing shown determines is identical.

It should be noted that in the above method 1 and method 2, however, it is determined that believe at the same moment or the same upload control HARQ-ACK feedback is carried out on road, then when feeding back according to the HARQ-ACK that SPS transmission opportunity and HARQ-ACK timing are determined Domain position phase is it is also desirable to determine that the time-domain position of PUCCH resource indicated in PDCCH is identical, i.e., character position is identical； It is of course also possible to not make this limitation, i.e., HARQ-ACK feedback is carried out in identical slot.

The above method that embodiment provides in order to further illustrate the present invention, illustrates below by specific embodiment The step of stating method.Wherein, in the present embodiment only with but be not limited in a radio frames include be that 10 slot illustrate.

As shown in figure 4, UE has been received one using SPS corresponding RNTI scrambling (such as CS- before slot n RNTI, Configured Scheduling RNTI) and NDI=0 PDCCH, the PDCCH indicate UE activate downlink SPS business Transmission, according in the PDCCH scheduling timing and the preconfigured SPS transmission intercal of high-level signaling (such as 10 Slot), determine that subsequent SPS transmission opportunity is the slot n+1 in each radio frames, and the SPS indicated in activation PDCCH HARQ-ACK timing is 3, i.e. the PDSCH transmitted in slot x carries out HARQ-ACK feedback in slot x+3, then slot n+1 In SPS PDSCH needs HARQ-ACK is fed back in slot n+4, there is also other with corresponding PDCCH's by slot n+4 PDSCH carries out HARQ-ACK feedback together with the SPS PDSCH in slot n+1.Wherein, in Fig. 4 by other with corresponding The PDSCH of PDCCH is referred to as dynamic PDSCH, and by downlink distribution index (Downlink Assignment Index, DAI value) scheduled how many PDSCH and indicating downlink the SPS moneys for having corresponding PDCCH to count up to the present to amount to The number of the PDCCH of source release, DAI can be used for obtaining these and transmit corresponding HARQ-ACK codebook.Because in DAI not The count information of SPS PDSCH comprising no corresponding PDCCH, therefore, it is necessary to the determined in slot n+4 according to DAI One HARQ-ACK codebook increases SPS HARQ-ACK.For example, it is assumed that the corresponding 1 bit HARQ-ACK of each PDSCH, then exist It needs to feed back the first HARQ-ACK codebook of 2 bit and 1 bit SPS HARQ-ACK in slot n+4, amounts to 3 bits HARQ-ACK.The PDSCH that HARQ-ACK feedback is carried out in slot n+9 does not include SPS PDSCH then, therefore, in slot n+9 It does not need to increase SPS HARQ-ACK for the first HARQ-ACK codebook generated based on DAI, i.e., is directly produced according to DAI Raw the first HARQ-ACK codebook of 4 bit is transmitted.It in next radio frames, handles in a similar way, always It is increase SPS HARQ-ACK in the first HARQ-ACK codebook needed in slot n+4, and in slot n+9 then not Need to increase SPS HARQ-ACK.

It, can be by some slot as the PDCCH that the configuration that base station needs to send instruction SPS transmission is updated One is sent using the corresponding RNTI scrambling (such as CS-RNTI, Configured Scheduling RNTI) of SPS and NDI= 0 PDCCH, since UE has been in SPS state of activation, PDCCH instruction UE updates the downlink SPS transmission activated Configuration, including update transmission opportunity, frequency domain resource, modulation and coding strategy (Modulation and Coding Scheme, MCS) the various information such as grade, HARQ-ACK timing.When base station updates the configuration of downlink SPS transmission by PDCCH, in order to The cause that understands differently of base station and terminal to the HARQ-ACK transmitted in each UL slot is avoided, base station and end-error are avoided HARQ-ACK transmission and parsing carry out HARQ-ACK feedback at the same moment with updated SPS before needing to guarantee to update.

The above method 1 is explained below by the mode of illustration:

Need to guarantee that subsequent SPS transmission opportunity determined by the PDCCH updated according to instruction SPS swashs with according to instruction SPS Subsequent SPS transmission opportunity determined by PDCCH living is consistent, and HARQ-ACK indicated by the PDCCH of instruction SPS update Timing is identical as HARQ-ACK timing indicated by the PDCCH of instruction SPS activation.As shown in figure sa or figure, for example, The PDCCH for indicating that SPS updates is transmitted in slot n+x, and scheduling timing instruction therein is in the slot n+1 of radio frames i PDSCH transmission is carried out, and indicates that HARQ-ACK timing=3 indicated by the PDCCH of SPS update (is activated with instruction SPS PDCCH indicated by HARQ-ACK timing it is identical).Wherein, x can be equal to 1 or less than 1.Such as x=1, then it dispatches Timing is 0, i.e. this slot scheduling；In another example x=0, then dispatching timing is 1, i.e. PDSCH in scheduling slot n+0+1； It is then identical as original SPS according to the PDCCH that instruction SPS the updates SPS transmission opportunity determined and HARQ-ACK timing, the instruction The PDCCH that SPS updates may only change the information such as the MCS of SPS, frequency domain resource location/size, therefore updated SPS is passed Slot n+1 in defeated chance or each radio frames, the slot in corresponding HARQ-ACK feedback position or each radio frames n+4。

Situation one,

If UE does not receive the PDCCH of instruction update SPS in the slot n+1 of radio frames i:

The side UE: due to including DAI in the PDCCH, then NACK is generated to the position slot n+1 according to DAI, and produce according to DAI Raw the first HARQ-ACK codebook of 2 bit transmitted in slot n+4；Since UE does not receive the finger of update SPS at this time Enable, then work also according to original SPS transmission opportunity and transmission configuration, as shown in Figure 5A, i.e. UE in slot n+1 according to The SPS resource that first wife sets receives SPS PDSCH, and generates 1 bit SPS HARQ-ACK, which is increased It is added to the first HARQ-ACK codebook, to obtain 3 bit HARQ-ACK feedback informations, is sent in slot n+4.

Base station side: understand according to the PDCCH that instruction SPS updates is had sent, match in slot n+1 according to updated SPS It sets and sends SPS PDSCH rather than configured according to former SPS, is i.e. uses new frequency domain resource/MCS grade SPS in slot n+1 The HARQ-ACK of PDSCH, and determine that terminal increases the HARQ-ACK of updated SPS PDSCH in slot n+4, therefore It is that determination receives in slot n+4 according to 3 bit HARQ-ACK feedback informations, to obtain the first HARQ-ACK of 2 bit Codebook and 1 bit SPS HARQ-ACK, as shown in Figure 5 B；Therefore, even if UE loses the PDCCH that instruction SPS updates, It will not influence reception of the base station to HARQ-ACK；Only difference is that the cause that understands differently for 1 bit SPS HARQ-ACK, That terminal is sent is the HARQ-ACK of former SPS, because real base station has updated SPS configuration, base station can be according to new resource distribution SPS PDSCH is transmitted, and terminal PDSCH when receiving SPS PDSCH in former SPS resource will not be correctly received, therefore eventually HARQ-ACK of the 1 obtained bit NACK as original SPS is held, and the 1 bit SPS HARQ-ACK received is actually recognized in base station To be occupy-place information, because the PDSCH in slot n+1 itself is that have DAI as scheduled in the PDCCH of instruction SPS update Information, HARQ-ACK are included in the first HARQ-ACK codebook according to DAI and suffer.Therefore, even if lost terminal should It indicates the PDCCH that SPS updates, nor affects on parsing of the base station to HARQ-ACK.

In next radio frames i+1, if UE does not receive the PDCCH that instruction SPS updates in slot n+1:

The side UE: if the implementation procedure of UE does not receive the instruction in the slot n+1 of radio frames i with above-mentioned UE and updates SPS PDCCH when implementation procedure.That is: UE is configured also according to former SPS and is received SPS PDSCH, then in the slot n of radio frames i+1 In+4, the first HARQ-ACK codebook of 3 bit is generated according to DAI, then increases by the HARQ- of 1 bit original SPS PDSCH ACK obtains 4 bit HARQ-ACK and transmits in slot n+4, as shown in Figure 5A.

Base station side: understand according to the PDCCH that instruction SPS updates is had sent, provided in slot n+1 according to updated SPS Source sends SPS PDSCH, and determines to include the first HARQ-ACK codebook and updated SPS in slot n+4 The HARQ-ACK of PDSCH, it is thus determined that HARQ-ACK is received in slot n+4 according to 4 bits, to obtain 3 bits first HARQ-ACK codebook obtains 1 bit SPS HARQ-ACK, as shown in Figure 5 B；Therefore, even if UE loses instruction, SPS updates PDCCH because update front and back SPS HARQ-ACK feedback position it is identical, will not influence base station and HARQ-ACK connect It receives.The only difference is that the cause that understands differently that SPS corresponding to 1 bit SPS PDSCH is transmitted in base station, base station is interpreted as slot According to the HARQ-ACK of the SPS PDSCH of updated SPS resource transmission in n+1, and terminal be interpreted as in slot n+1 according to The HARQ-ACK of the SPS PDSCH of SPS resource transmission before update, but if UE loses the PDCCH that instruction SPS updates, base station SPS PDSCH is sent according to information such as new frequency domain resource/MCS, and terminal receives SPS according to former frequency domain resource/MCS grade PDSCH, the SPS PDSCH that terminal receives are unable to correct decoding, and feedback information is exactly NACK, and terminal does not receive base Stand the SPS PDSCH sent according to updated SPS frequency domain resource/MCS, and the feedback information of the SPS PDSCH is also NACK, then Base station is not influenced using the NACK as the feedback information of updated SPS PDSCH to understand.If UE is received in slot n+1 The PDCCH that instruction SPS updates is arrived, then with reference to the implementation procedure for having received PDCCH in following situations two.

Situation two,

If UE has received the PDCCH of instruction SPS update in the slot n+1 of radio frames i:

The side UE: it determines that updated subsequent SPS transmission opportunity is identical as original SPS transmission opportunity according to the PDCCH, is similarly Slot n+1 in each radio frames, i.e., it is a kind of to understand slot n+1 or current SPS conveyer it is considered that radio frames i Meeting, i.e., in the slot n+1 or original SPS is configured, and according to the PDCCH for indicating that SPS updates in the slot n+1 of radio frames i It is anti-that the slot n+4 that SPS PDSCH in identified subsequent SPS transmission opportunity is not included in radio frames i carries out HARQ-ACK Feedback, the HARQ-ACK of the PDCCH itself that instruction SPS updates scheduled PDSCH, which is counted according to DAI, is included in first In HARQ-ACK codebook, do not need additionally to generate feedback information；Another kind is interpreted as, since UE is in the slot of radio frames i The PDCCH that instruction SPS updates is received in n+1, it is determined that SPS transmission configuration updates in the slot n+1 of radio frames i, generates 1 The HARQ-ACK of the updated SPS PDSCH of bit；As shown in Figure 5 B, anyway understand, do not change UE and be in SPS It needs to feed back comprising 1 SPS HARQ-ACK in the slot n+4 of state of activation and radio frames i, then in the slot n+ of radio frames i In 4, need to increase by the first HARQ-ACK codebook the HARQ-ACK for being directed to SPS PDSCH, to obtain 3 bit HARQ- ACK。

Base station side: similarly the side UE understands, can also determine in the slot n+4 of radio frames i as 3 bit HARQ-ACK；

For the slot n+1 in subsequent radio frames i+1, then terminal and base station are regarded as being passed according to the SPS of update Defeated.

By situation one in the above method 1 and situation two as it can be seen that no matter whether UE receives the PDCCH that instruction SPS updates, by It is consistent in the SPS HARQ-ACK feedback position for updating front and back, do not change UE and is in SPS state of activation and slot n+4 In comprising SPS HARQ-ACK need the state fed back, then in slot n+4, it is always necessary to the first HARQ-ACK Codebook increases the HARQ-ACK for being directed to SPS PDSCH, to ensure that the understanding one of terminal and base station to number of bits of feedback It causes.

The above method 2 is explained below by the mode of illustration:

Need to guarantee that subsequent SPS transmission opportunity determined by the PDCCH updated according to instruction SPS and instruction SPS update PDCCH indicated by the corresponding HARQ-ACK feedback bit of updated SPS transmission determined by HARQ-ACK timing It sets, the PDCCH updated with the subsequent SPS transmission opportunity according to determined by the PDCCH of instruction SPS activation and instruction SPS is signified HARQ-ACK feedback position corresponding to SPS transmission before updating determined by the HARQ-ACK timing shown is identical.

As shown in Fig. 6 A, 6B or 6C, for example, the PDCCH that instruction SPS updates is transmitted in slot n+x, scheduling therein Timing instruction carries out PDSCH transmission in slot n and (transmits different from the SPS according to determined by the PDCCH of instruction SPS activation Chance), and indicate (the PDCCH institute activated with instruction SPS of HARQ-ACK timing=4 indicated by the PDCCH of SPS update The HARQ-ACK timing of instruction is different), wherein x can be equal to 0 or less than 0.Such as x=0, then dispatching timing is 0, That is this slot scheduling, in another example x=-1, then dispatching timing is 1, i.e. PDSCH in scheduling slot n+ (- 1)+1.On although It is different from information determined by the PDCCH activated according to instruction SPS to state information, but due to SPS transmission opportunity and HARQ-ACK Timing is changed simultaneously, and final function and effect are all to carry out HARQ- in the slot corresponding to former SPS PDSCH transmission ACK feedback.

Situation one,

If terminal does not receive the PDCCH of instruction SPS update in the slot n of radio frames i:

The side UE: including DAI in the PDCCH, then generates NACK to the position slot n according to DAI, generates 2 bits according to DAI It needs to the first HARQ-ACK codebook transmitted in slot n+4；Since UE does not receive the instruction of update SPS at this time, It then works also according to original SPS transmission opportunity and transmission configuration, as shown in Figure 6A, i.e. UE is in slot n+1 according to first wife The SPS resource set receives SPS PDSCH, and generates 1 bit SPS HARQ-ACK, which is increased to the first HARQ-ACK Codebook is transmitted in slot n+4 to obtain 3 bit HARQ-ACK feedback informations.

Base station side: understand according to the PDCCH that instruction SPS updates is had sent, the SPS transmission opportunity slot n of meeting in the updated Middle transmission SPS PDSCH without in slot n+1 send SPS PDSCH, and determine terminal increase in slot n+4 update after SPS PDSCH HARQ-ACK, the i.e. HARQ-ACK of SPS PDSCH in slot n, as shown in Figure 6B, therefore be also to determine HARQ-ACK is received in slot n+4 according to 3 bits, to obtain the first HARQ-ACK codebook of 2 bit, obtains 1 ratio Special SPS HARQ-ACK；Even if both UE loses the PDCCH that instruction SPS updates, reception of the base station to HARQ-ACK will not influence；Only One the difference is that the cause that understands differently for 1 bit SPS HARQ-ACK, that terminal is sent is the HARQ-ACK of former SPS, because SPS configuration is had updated for real base station, base station can transmit SPS PDSCH according to new resource distribution in new SPS chance, and Terminal PDSCH when receiving SPS PDSCH in former SPS resource will not be correctly received, therefore the 1 bit NACK that terminal obtains As SPS HARQ-ACK, and the 1 bit SPS HARQ-ACK received is considered occupy-place information by base station reality, because itself PDSCH in slot n+5 is that have DAI information, HARQ-ACK root scheduled in the PDCCH that is updated as instruction SPS The first HARQ-ACK codebook is included according to DAI to suffer；Therefore, even if the PDCCH of lost terminal instruction SPS activation, Parsing of the base station to HARQ-ACK is not influenced.

In next radio frames i+1, if UE does not receive the PDCCH that instruction SPS updates in slot n:

The side UE: the implementation procedure of UE is same as above, and is configured also according to former SPS and is received SPS PDSCH, then in slot n+4, The first HARQ-ACK codebook of 3 bit is generated according to DAI, then increases by the HARQ-ACK of 1 bit original SPS PDSCH, obtains 4 bit HARQ-ACK are transmitted in slot n+4, as shown in Figure 6A.

Base station side: understand according to the PDCCH that instruction SPS updates is had sent, provided in slot n+1 according to updated SPS Source sends SPS PDSCH, and determines to include the first HARQ-ACK codebook and updated SPS in slot n+4 The HARQ-ACK of PDSCH, as shown in Figure 6B, it is thus determined that HARQ-ACK is received in slot n+4 according to 4 bits, to obtain The first HARQ-ACK codebook of 3 bit obtains 1 bit SPS HARQ-ACK；Even if both UE loses what instruction SPS updated PDCCH will not influence reception of the base station to HARQ-ACK because the feedback position for updating the SPS HARQ-ACK of front and back is identical； The only difference is that the cause that understands differently that SPS corresponding to 1 bit SPS PDSCH is transmitted in base station, base station is not understood as slot According to the HARQ-ACK of the SPS PDSCH of updated SPS resource transmission in n, and terminal be not understood as in slot n+1 according to The HARQ-ACK of the SPS PDSCH of SPS resource transmission before update, but if UE loses the PDCCH that instruction SPS updates, base station SPS PDSCH is sent according to new position, and terminal receives SPS PDSCH in old position, the SPS PDSCH that terminal receives cannot Correct decoding, feedback information is exactly NACK, and terminal does not receive base station according to updated SPS transmission opportunity and matches The SPS PDSCH of transmission is set, the feedback information of the SPS PDSCH is also NACK, then does not influence base station using the NACK as update The feedback information of SPS PDSCH afterwards understands；If UE has received the PDCCH that instruction SPS updates in slot n, refer to Following implementation procedures for having received PDCCH；

Situation two,

If UE receives the PDCCH of instruction SPS update in the slot n of radio frames i:

The side UE: determine that updated subsequent SPS transmission opportunity is the slot n in each radio frames according to the PDCCH, i.e., It is a kind of understand it is considered that: slot n+1 or current SPS transmission opportunity, i.e., in slot n+1 or original SPS configure, and It is not included according to the SPS PDSCH in subsequent SPS transmission opportunity determined by the PDCCH for indicating SPS update in slot n Slot n+4 carries out HARQ-ACK feedback, the HARQ-ACK of the PDCCH itself that instruction SPS updates scheduled PDSCH root It counts and is included in the first HARQ-ACK codebook according to DAI, do not need additionally to generate feedback information, as shown in Figure 6 C；It is another Kind, which understands, can consider: since UE receives the PDCCH that instruction SPS updates in slot n, it is determined that base station will not be in slot n+ SPS PDSCH (i.e. original SPS has been updated, and new SPS transmission opportunity is slot n) is sent in 1, then is deposited in slot n+4 The HARQ-ACK of SPS in the updated, as shown in Figure 6B；Anyway understand, does not change UE and be in SPS state of activation And need to feed back comprising 1 SPS HARQ-ACK in slot n+4, then in slot n+4, need to the first HARQ-ACK Codebook increases the HARQ-ACK for being directed to SPS PDSCH, to obtain 3 bit HARQ-ACK.

Base station side: similarly the side UE understands, base station side can also be determined and be received in slot n+4 according to 3 bit HARQ-ACK HARQ-ACK。

For in subsequent radio frames i+1, what terminal and base station were regarded as being transmitted according to the SPS of update, that is, exist There are SPS transmission in slot n.

By situation one in the above method 2 and situation two as it can be seen that no matter whether UE receives the PDCCH that instruction SPS updates, by It is consistent in the SPS HARQ-ACK feedback position for updating front and back, do not change UE and is in SPS state of activation and slot n+4 In need to feed back comprising SPS HARQ-ACK, then in slot n+4, it is always necessary to increase the first HARQ-ACK codebook For the HARQ-ACK of SPS PDSCH, to guarantee that terminal is consistent with understanding of the base station to number of bits of feedback.

It should be noted that above-described embodiment is only explained by taking scheduling and transmission based on slot as an example how identical Time-domain position transmits the feedback information of HARQ-ACK, and terminal and network side is made to understand one to the feedback information of the HARQ-ACK It causes, but is not limited to the above embodiment, can also such as be carried out when based on mini-slot using being illustrated for other modes When scheduling and transmission, the above method can be equally used.Something in common, details are not described herein.In addition, in the above-described embodiments only It is illustrated for increasing SPS HARQ-ACK to the first HARQ-ACK codebook, when needing in a particular embodiment When reducing SPS HARQ-ACK to the first HARQ-ACK codebook, aforesaid way is equally applicable.In above-described embodiment, with It simultaneously include for HARQ-ACK instructions field and time domain instructions field in PDCCH, if only including a kind of instructions field, another is indicated The corresponding content in domain may be considered fixed value, then the above method is equally applicable, if instruction SPS updates and the PDCCH of activation In do not include HARQ-ACK timing instructions field and include time domain instructions field, then using being pre-configured with or arrange same HARQ-ACK timing corresponding to HARQ-ACK timing, the i.e. PDCCH of instruction SPS update and activation is inherently identical, It then only needs to guarantee identical according to the time-domain position of the scheduling timing of the time domain instructions field instruction in the PDCCH PDSCH determined (it can be the identical PDCCH transmission location of identical scheduling timing or different PDCCH transmission locations and not at this time Same scheduling timing, but scheduling result is the PDSCH in identical slot), that is, it can guarantee that SPS transmission opportunity is identical, to protect Demonstrate,prove identical feedback position；If indicate SPS update and activation PDCCH in comprising HARQ-ACK timing instructions field without Comprising time domain instructions field, then the preconfigured same scheduling timing is used, i.e. instruction SPS updates and the PDCCH institute of activation Corresponding scheduling timing is inherently identical, then if instruction SPS updates and the PDCCH of activation is sent at the time of identical, It can determine the same PDSCH transmission moment, that is, can guarantee that SPS transmission opportunity is identical, also needs to guarantee to indicate at this time identical HARQ-ACK timing can guarantee identical feedback position, if instruction SPS updates and the PDCCH of activation is when different It carves and sends, then can determine the different PDSCH transmission moment, need to indicate different HARQ-ACK timing, also at this time to reach It can guarantee the purpose of identical feedback position；If indicating not including HARQ-ACK in the PDCCH of SPS update and activation Timing instructions field does not include time domain instructions field yet, then uses identical HARQ-ACK timing and identical scheduling Timing, it is only necessary to guarantee that instruction SPS updates and the PDCCH of activation is sent at the time of identical, then can determine same The PDSCH transmission moment can guarantee that SPS transmission opportunity is identical, to guarantee identical feedback position, no longer illustrates herein It is bright.

In conclusion in terminal side, referring to Fig. 7, a kind of hybrid automatic repeat-request response provided in an embodiment of the present invention Transmission method, this method comprises:
