Therefore, it should not be interpreted on the scale and configuration relationship of the attached drawings, and applications that limit the actual implementation of the invention should not be interpreted. The scope is stated first.

In the description of the present invention, it should be understood that the terms "center", "horizontal", "upper", "downward", "left", "right", "top", "bottom", "inner", " Direction or location The relationship is based on the orientation or positional relationship shown in the diagram, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore It cannot be understood as a limitation to the present invention.

First, some concepts mentioned in the embodiments of the present invention are described as follows.

In the fifth-generation mobile communication technology (5th-Generation, 5G) New Radio (NR) system, it supports Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH) Transmission and PDSCH (ie dynamic PDCSH) transmission with a corresponding Physical Downlink Control Channel (PDCCH). When the SPS PDSCH service is configured, the high-level signaling will configure the radio network temporary identity (RNTI) corresponding to the SPS accordingly, which is used to scramble the PDCCH for the SPS PDSCH, and the high-level signaling will also be configured accordingly SPS PDSCH transmission interval.

The high-level signaling pre-configures N candidate Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK) timing values for the terminal, where the value of N ranges from 1 to 8. The HARQ-ACK timing of the PDSCH with the PDCCH is indicated by the [log ₂ (N)] bit HARQ-ACK timing indicator field in the PDCCH to indicate any one of the N values pre-configured by higher layer signaling. For SPS PDSCH, since there is no corresponding PDCCH, the HARQ-ACK timing of SPS PDSCH is determined by the HARQ-ACK timing indicator field in the PDCCH that initiates SPS PDSCH transmission. The same HARQ-ACK timing value is used during SPS PDSCH transmission. .

For PDSCH transmission with PDCCH, the physical uplink control channel (PUCCH) resource used for HARQ-ACK feedback is based on The PUCCH resource indication (PUCCH Resource Indication, PRI) information field in the PDCCH is determined. The high-level signaling pre-configures 8-16 candidate PUCCH resources for the terminal, and is indicated by the 3-bit PRI in the PDCCH (when the number of configured PUCCH resources is greater than 8, the control channel element (CCE) of the PDCCH needs to be combined Index is determined) The terminal uses one of them. For SPS PDSCH transmission, if the corresponding HARQ-ACK and the HARQ-ACK corresponding to the PDSCH transmission with the PDCCH are fed back in the same time slot, they are multiplexed on the PUCCH resource corresponding to the PDSCH with the PDCCH for transmission. If there is only HARQ-ACK feedback corresponding to SPS PDSCH transmission in a time slot, since there is no corresponding PDCCH, the PUCCH resource determined to be used by the PRI in the PDCCH cannot be used. The agreement stipulates that SPS PDSCH is configured with dedicated PUCCH resources through high-level signaling, and PUCCH format 0 or PUCCH format 1 can be used. Therefore, the dedicated PUCCH resources for SPS PDSCH support a maximum of 2 bits of HARQ-ACK feedback.

When only one SPS PDSCH transmission is configured, if the terminal only receives one SPS PDSCH, it will give feedback on its corresponding dedicated PUCCH resource. The current problem is that when SPS PDSCH transmission is configured on multiple carriers in a carrier group at the same time, if the terminal only receives two SPS PDSCHs that are fed back in the same time slot, the two SPS PDSCHs may correspond to different PUCCH resources. According to Rel-15, only one PUCCH is allowed to transmit HARQ-ACK in a time slot, so the terminal cannot use two different PUCCH resources to transmit the HARQ-ACK feedback information corresponding to the SPS PDSCH separately. Alternatively, multiple PUCCHs may be supported to carry HARQ-ACK in Rel-16, but when the PUCCH resources corresponding to two SPS PDSCHs overlap in time, the terminal cannot transmit the two PUCCH resources at the same time. If the HARQ-ACK feedback information corresponding to one of the SPS PDSCHs is discarded, the base station will not know whether the terminal has received the SPS PDSCH transmission correctly, which will affect its transmission performance. Therefore, in order to avoid To avoid discarding the HARQ-ACK feedback information of the SPS PDSCH, it is necessary to multiplex and transmit the HARQ-ACK information of the two SPS PDSCHs, but there is currently no clear plan.

The present invention is aimed at when only one PUCCH is allowed to transmit HARQ-ACK in a time slot or when the PUCCH resources corresponding to two SPS PDSCHs overlap in time, the related HARQ-ACK transmission mechanism cannot make multiple HARQ-ACKs effective feedback , There is a problem of low transmission performance. A hybrid automatic retransmission feedback method, receiving method, terminal, network equipment and computer-readable storage medium are provided.

As shown in Figure 1, the feedback method for hybrid automatic retransmission according to an embodiment of the present invention is applied to a terminal and includes: Step 11. When the terminal is in the same time slot, it needs to perform downlink shared channel SPS PDSCH for at least two semi-persistent scheduling entities. When the transmission is fed back, it is determined that the first physical uplink control channel PUCCH resource of the hybrid automatic repeat response information HARQ-ACK for at least two SPS PDSCH transmissions is fed back; it should be noted that the SPS PDSCH transmission mentioned in the embodiment of the present invention It can refer to the actual received SPS PDSCH transmission, or it can also refer to the SPS PDSCH transmission opportunity, that is, at least two SPS PDSCH transmissions include: actual received SPS PDSCH transmission that needs feedback and/or needs feedback Further, the SPS PDSCH transmission opportunity requiring feedback refers to: in the SPS PDSCH transmission opportunity, the terminal does not receive the SPS PDSCH transmission, but still needs to feedback it.

It should be noted that the time slot may be a time slot with 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols, or a sub-slot with less than 14 OFDM symbols.

The first PUCCH resource is one or several of the PUCCH resources corresponding to at least two SPS PDSCH transmissions.

Step 12: Multiplex the HARQ-ACKs transmitted by the at least two SPS PDSCHs on the first PUCCH resource; by multiplexing HARQ-ACKs on the same PUCCH resource, multiple HARQ-ACKs can be performed on the same time slot. Transmission.

Step 13. The HARQ-ACK transmitted by the at least two SPS PDSCHs is fed back to the network device through the first PUCCH resource.

It should be noted that the specific implementation of the above step 11 is: according to a preset rule, determine the first PUCCH resource that feeds back the HARQ-ACK transmitted by the at least two SPS PDSCHs.

The aforementioned preset rules can be implemented in one or more of the following ways.

Method A1: Use the PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number as the first PUCCH resource; it should be noted that since the SPS PDSCH transmission will be performed on the corresponding carrier, each SPS PDSCH transmission will correspond to one Carriers, and different carriers will be distinguished by different carrier numbers. In this way, the PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number is selected for HARQ-ACK multiplexing.

Manner A2: Among the PUCCH resources corresponding to the at least two SPS PDSCH transmissions, determine the PUCCH resource with the latest start time as the first PUCCH resource; it should be noted that the distribution time of different PUCCH resources on the time slot is different. Similarly, the start time mentioned above refers to the time when PUCCH resource transmission starts; in this implementation, it is The PUCCH resource with the latest PUCCH resource transmission start time is selected to perform HARQ-ACK multiplexing.

Manner A3: Among the PUCCH resources corresponding to the at least two SPS PDSCH transmissions, the PUCCH resource corresponding to the latest SPS PDSCH is determined as the first PUCCH resource; it should be noted that the PUCCH resource corresponding to the latest SPS PDSCH Refers to the PUCCH resource corresponding to the latest SPS PDSCH received or the PUCCH resource corresponding to the latest SPS PDSCH transmission opportunity; further, the latest SPS PDSCH is the most recent SPS PDSCH in the order of carrier number and/or the order of reception time. Late SPS PDSCH; for example, the latest SPS PDSCH can be determined only in the order of carrier number; it can also be determined only in the order of reception time; it can also be determined in the order of carrier number and reception time at the same time The latest SPS PDSCH, in this case, the terminal can first determine the order of the carrier number and then the order of the receiving time; the terminal can also determine the order of the receiving time first and then the order of the carrier number.

Method A4: When the PUCCH resources corresponding to the at least two SPS PDSCH transmissions use different PUCCH formats, the first PUCCH resource is determined according to the PUCCH format; further, this implementation method is specifically: determining according to the PUCCH format The PUCCH resource corresponding to the first PUCCH format is used as the first PUCCH resource.

It should be noted that the first PUCCH format refers to any one of PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, PUCCH format 4, that is, the PUCCH format 0 or PUCCH format 1 or PUCCH Format 2 or PUCCH The PUCCH resource in format 3 or PUCCH format 4 is selected as the resource with the highest priority.

Specifically, when at least one SPS PDSCH is configured to carry a PUCCH resource larger than 2 bits, any one of PUCCH format 2, PUCCH format 3, and PUCCH format 4 is selected as the first PUCCH resource. It should be noted that since PUCCH format 2, PUCCH format 3, and PUCCH format 4 carry at least 3 bits of HARQ-ACK information, when the SPS PDSCH feedback information is less than 3 bits, it can be obtained by padded 0 at the end 3-bit HARQ-ACK feedback information.

Method A5: When the network device configures two PUCCH resources for at least one SPS PDSCH of the at least two SPS PDSCHs, one PUCCH resource uses the second PUCCH format that is less than or equal to 2 bits, and the other PUCCH resource uses the bearer When the third PUCCH format is larger than 2 bits, the preset rule is implemented in one of the following ways.

Method A51: When two SPS PDSCH transmissions need to be fed back, the PUCCH resource using the second PUCCH format is determined as the first PUCCH resource; a further implementation method is: using the second PUCCH resource corresponding to the two SPS PDSCH transmissions Among the PUCCH resources in the second PUCCH format, one PUCCH resource is selected and determined as the first PUCCH resource; in general, the selection range of the PUCCH resource is all PUCCH resources in the second PUCCH format corresponding to two SPS PDSCH transmissions. In the specific selection method, the corresponding second-format PUCCH resource can be selected according to the SPS PDSCH with the later transmission end position, or the corresponding second-format PUCCH resource can be selected according to the smallest carrier number of the SPS PDSCH or the largest carrier number of the SPS PDSCH. It is also possible to select the second format PUCCH resources corresponding to the two SPS PDSCHs Start the latest PUCCH resource.

It should be noted that the foregoing second PUCCH format includes PUCCH format 0 and PUCCH format 1.

For example, when there are two SPS PDSCH transmissions, the format of PUCCH resource 1 corresponding to the first SPS PDSCH transmission is PUCCH format 0, and the format of PUCCH resource 2 is PUCCH format 2; the second SPS PDSCH transmission corresponds to the format of PUCCH resource 3. The format is PUCCH format 1, and the format of PUCCH resource 4 is PUCCH format 3. According to the above implementation, one of PUCCH resource 1 and PUCCH resource 3 corresponding to PUCCH format 0 and PUCCH format 1 respectively is selected as the multiplexing of two SPS. PUCCH resource of HARQ-ACK for PDSCH transmission.

Method A52: When more than two SPS PDSCH transmissions need to be fed back, the PUCCH resource using the third PUCCH format is determined as the first PUCCH resource; a further implementation method is: in the more than two SPS PDSCH transmissions Among the corresponding PUCCH resources that use the third PUCCH format, select one PUCCH resource and determine it as the first PUCCH resource; in general, the selection range of PUCCH resources is more than two SPS PDSCH transmissions corresponding to all PUCCHs that use the third PUCCH format. Resources. The specific selection method can be selected according to one of the following rules or a combination of two or three rules: 1) Select the SPS PDSCH transmission with the latest transmission end position among the more than two SPS PDSCH transmissions and select the corresponding third format PUCCH resource; 2) Select the third format PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number or the largest carrier number among the more than two SPS PDSCH transmissions; 3) Select the third format PUCCH resource corresponding to the more than two SPS PDSCH transmissions The PUCCH resource with the latest start among the three-format PUCCH resources.

It should be noted that the foregoing third PUCCH format includes PUCCH format 2, PUCCH format 3, and PUCCH format 4.

For example, there are three SPS PDSCH transmissions, which are located on three carriers. The first SPS PDSCH transmission is located on carrier 1. The corresponding PUCCH resource 1 format is PUCCH format 3, and the format of PUCCH resource 2 is PUCCH format 0; the second The SPS PDSCH transmission is on carrier 2, and the corresponding PUCCH resource 3 is in PUCCH format 4, and the format of PUCCH resource 4 is PUCCH format 1. The third SPS PDSCH transmission is on carrier 3, and the corresponding PUCCH resource 5 is in PUCCH format 4. , The format of PUCCH resource 6 is PUCCH format 1. According to the foregoing implementation manner, one PUCCH resource determined as HARQ-ACK for multiplexing three SPS PDSCH transmissions is selected from PUCCH resource 1 and PUCCH resource 3 and PUCCH resource 5 corresponding to PUCCH format 3 and PUCCH format 4. When selecting among the three PUCCH resources, specifically, the third format PUCCH resource corresponding to SPS PDSCH transmission with the smallest carrier number can be selected, for example, PUCCH resource 1 corresponding to SPS PDSCH transmission on carrier 1 is selected; or, SPS is selected The SPS with the latest transmission end position in PDSCH transmission selects the corresponding third format PUCCH resource. If the end position of SPS PDSCH transmission on carrier 3 is the latest, select PUCCH resource 5 corresponding to SPS PDSCH transmission on carrier 3; or, select SPS The latest PUCCH resource in the third format PUCCH resource corresponding to PDSCH transmission. For example, in PUCCH resource 1, PUCCH resource 3 and PUCCH resource 5, the end position of PUCCH resource 3 is the latest, then PUCCH resource 3 can be selected as multiplexing PUCCH resources of HARQ-ACK transmitted by three SPS PDSCHs.

It should also be noted that step 12 in some embodiments of the present invention may be implemented in at least one of the following ways.

Way B1: The HARQ-ACKs transmitted by at least two SPS PDSCHs are concatenated in the order of ascending carrier number and/or the order of reception time to generate a feedback codebook; and the feedback codebook is carried on the first PUCCH resource.

It should be noted that when cascading to generate the feedback codebook, the terminal can only perform the cascading in the order of ascending the carrier number of the carrier on which the SPS PDSCH transmission is located; or only in the order of the time when the terminal receives the SPS PDSCH transmission. Cascading; the terminal can also concatenate the HARQ-ACK of the SPS PDSCH transmission in the order of the ascending order of the carrier number of the carrier where the SPS PDSCH transmission is located and the order of the time the terminal receives the SPS PDSCH transmission. In this case, the terminal The cascading can be performed in the order of ascending the carrier number first and then the order of the receiving time, or the cascading can be performed in the order of the receiving time first and then the ascending carrier number.

Manner B2: When there are two SPS PDSCH transmissions that need to be fed back in the same time slot, and the PUCCH resources corresponding to the two SPS PDSCH transmissions both use the first PUCCH format, this step 12 is implemented in one of the following manners.

Method B21: According to the initial cyclic shift meta parameter configured by the network device for the first PUCCH resource and the cyclic shift offset parameter of the transmission sequence corresponding to the 2-bit HARQ-ACK, determine the corresponding two-bit HARQ-ACK A transmission sequence, carrying the transmission sequence on the resource block of the first PUCCH resource;

Method B22: If the initial cyclic shift element parameters configured by the network device for the PUCCH resources corresponding to the two SPS PDSCH transmissions are different, use the initial cyclic shifts respectively configured by the network device for the PUCCH resources corresponding to the two SPS PDSCH transmissions Meta parameter, determine the transmission sequence corresponding to the two-bit HARQ-ACK, and carry the transmission sequence in the first PUCCH resource Resource block.

It should be noted that, in mode B22, the terminal can determine the HARQ-ACK transmission sequence through the corresponding relationship given in Table 1.

It should be noted that the aforementioned initial cyclic shift parameter corresponds to m _{0 in} Table 1.

Method B3: When there are more than two SPS PDSCH transmissions that need to be fed back in the same time slot, and the network equipment uses PUCCH resources configured for each of at least two SPS PDSCHs, the use bearer is less than or equal to 2 bits In the second PUCCH format, step 12 is implemented in the following manner: combine the HARQ-ACK feedback bits transmitted by the at least two SPS PDSCH to generate feedback information less than or equal to 2 bits; and carry the feedback information on On the first PUCCH resource.

It should be noted that the implementation manner of combining HARQ-ACK feedback bits includes the following two implementation manners.

Method B31: Perform an AND operation on the 1-bit HARQ-ACKs transmitted by the at least two SPS PDSCHs to generate 1-bit feedback information.

Method B32: Divide the at least two SPS PDSCH transmissions into two groups, and perform the AND operation on the HARQ-ACK transmitted by the SPS PDSCH in each group to generate 1-bit feedback information. The SPS PDSCH group generates a total of 2 bits of feedback information;

It should be noted that, in this case, one bit is generated for each SPS PDSCH transmission in each group, and then all the bits in each group are directly merged.

Way B4:

When there are two SPS PDSCH transmissions that need to be fed back in the same time slot, and the PUCCH resources configured by the network device for each of the two SPS PDSCHs use the third PUCCH format that carries more than 2 bits , The implementation of step 12 is: when the number of bits in the HARQ-ACK feedback bit sequence transmitted by the two SPS PDSCHs (the number of bits refers to the number of HARQ-ACK feedback bit sequences transmitted by the two SPS PDSCHs) When the total number of bits) is less than the number of bits of the minimum uplink control information UCI transmitted corresponding to the third PUCCH format, the HARQ-ACK feedback bit sequence transmitted by the two SPS PDSCHs is supplemented with target bits; The HARQ-ACK feedback bit sequence is carried on the first PUCCH resource; wherein the number of target bits is equal to the minimum UCI bit number minus the HARQ-ACK feedback bit sequence.

It should be noted that this method means that when the number of bits that can be carried by the selected PUCCH format is greater than the number of HARQ-ACK bits that need to be fed back, then the HARQ-ACK bits are not filled. Zero (or NACK complement) processing, under normal circumstances, HARQ-ACK occupies the higher bit, and the bit for zero padding is placed at the end of the PUCCH format. For example, when the selected PUCCH format is PUCCH format 2, it is used to carry the HARQ-ACK feedback information greater than 2 bits, and the HARQ-ACK bit to be returned is 1 bit, then 1 bit of the HARQ-ACK to be returned Two zeros are added after the element to generate a total of 3 bits of feedback information, which is actually in PUCCH format 2. It transmits 3 bits of HARQ-ACK feedback information, and the first bit is the HARQ-ACK bit that needs to be returned.

It should be noted that when the first PUCCH resource uses PUCCH format one (that is, the above-mentioned PUCCH format 1), the specific implementation of the above step 13 is: when the first PUCCH resource uses PUCCH format one, according to the at least two SPS PDSCH transmission obtains a HARQ-ACK feedback bit sequence, modulates the HARQ-ACK feedback bit sequence to obtain a modulation symbol, and places the modulation symbol on the first PUCCH resource using PUCCH format one for transmission.

Specifically, the method for modulating the HARQ-ACK feedback bit sequence includes: a quadrature amplitude modulation (QAM) method or a phase shift keying (PSK) modulation method.

For example, if two SPS PDSCH transmissions need to be fed back, the 2-bit feedback information corresponding to the two SPS PDSCH transmissions is subjected to QPSK modulation or 4QAM modulation to obtain a QPSK or 4QAM modulation symbol on the PUCCH resource of PUCCH format 1. Transmission; or if you need to feed back three SPS PDSCH transmissions, perform 8QAM modulation or 8PSK modulation on the 3-bit feedback information corresponding to the three SPS PDSCH transmissions to obtain a PUCCH resource with an 8QAM or 8PSK modulation symbol in PUCCH format 1 If you need to provide feedback for four SPS PDSCH transmissions, perform 16QAM modulation or 16PSK modulation on the 4-bit feedback information corresponding to the four SPS PDSCH transmissions to obtain a 16QAM or 16PSK modulation symbol in PUCCH format 1. Transmission on PUCCH resources; or if five SPS PDSCH transmissions need to be fed back, perform 32QAM modulation or 32PSK modulation on the 5-bit feedback information corresponding to the five SPS PDSCH transmissions to obtain a 32QAM or 32PSK modulation symbols are transmitted on the PUCCH resource of PUCCH format 1; or if six SPS PDSCH transmissions need to be fed back, the 6-bit feedback information corresponding to the six SPS PDSCH transmissions is subjected to 64QAM modulation or 64PSK modulation to obtain one 64QAM or 64PSK modulation symbols are transmitted on the PUCCH resource of PUCCH format 1; or if seven SPS PDSCH transmissions need to be fed back, the 7-bit feedback information corresponding to the seven SPS PDSCH transmissions is 128QAM modulated or 128PSK modulated, Obtain a 128QAM or 128PSK modulation symbol for transmission on the PUCCH resource of PUCCH format 1. If eight SPS PDSCH transmissions need to be fed back, the 8-bit feedback information corresponding to the eight SPS PDSCH transmissions is modulated by 256QAM or 256PSK. , Get a 256QAM or 256PSK modulation symbol for transmission on the PUCCH resource of PUCCH format 1.

It should be noted that the above-mentioned modulation method only gives the HARQ-ACK feedback information of 2 to 8 bits, and the cases larger than 8 bits are not listed one by one, and one modulation symbol can be generated through QAM or PSK modulation.

It should be noted that in actual applications, different modulation orders may not be used for each bit number. You can choose to define and use some of the better modulation orders, and then for some bits that do not have a corresponding modulation order definition. The number is complemented by 0 to make it reach the number of bits defined by the corresponding modulation order, and then the corresponding modulation order is used for modulation. For example, X bits can use the same modulation method as [X /2]*2 bits. Specifically, if the values of X and [X /2] * 2 are different, the X bit is converted to [ X /2] * 2 bits ^{by adding 0 at the end, and then 2 [ X /2] is used. *2} QAM or (2) ^{[ X /2] *2} PSK modulation mode for modulation, where X is a positive integer greater than or equal to 2.

It should be noted that the network equipment side is similar to the terminal side and also transmits the first PUCCH of HARQ-ACK for at least two SPS PDSCH transmissions based on the above-mentioned similar rules. The determination of resources and the determination of feedback information.

In the following, some embodiments of the present invention will be exemplified in specific applications as follows.

Application scenario 1: Assume that the base station (that is, the network equipment mentioned above) configures two carriers for the terminal, and the configured K1 set is {1,2,3,4,5}. As shown in Figure 2, assuming that the base station is configured with SPS PDSCH transmission on both carriers, in the start signaling corresponding to the SPS PDSCH on carrier 1, the downlink control information (DCI) indicates that the HARQ feedback sequence used is 4. In the start signaling corresponding to the SPS PDSCH on carrier 2, the HARQ feedback sequence indicated by DCI is 5. If the SPS PDSCH on carrier 1 exists in time slot n-4, and the SPS PDSCH on carrier 2 exists in time slot n-5, then the HARQ-ACK feedback of the SPS PDSCH on the two carriers is transmitted in time slot n. Suppose that the HARQ-ACK of the SPS PDSCH on carrier 1 corresponds to PUCCH resource 1 configured by high-level signaling, and the HARQ-ACK of SPS PDSCH on carrier 2 corresponds to PUCCH resource 2 configured by high-level signaling. Both PUCCH resource 1 and PUCCH resource 2 correspond to the largest bearer The 2-bit PUCCH format. When the terminal receives only two SPS PDSCH transmissions from time slot n-5 to time slot n-1, the terminal selects PUCCH resources in the following manner.

Method 1: The terminal selects the PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number, that is, selects the PUCCH resource 1 corresponding to the SPS PDSCH transmission on the carrier 1 to transmit the HARQ-ACK information of the two SPS PDSCHs.

Method 2: The terminal selects the PUCCH resource with the latest start time among all PUCCH resources corresponding to SPS PDSCH transmission, that is, selects the PUCCH resource with the latest start time among PUCCH resource 1 and PUCCH resource 2, that is, the terminal finally selects PUCCH resource 2 to transmit two HARQ-ACK information of SPS PDSCH.

Method 3: The terminal selects the PUCCH resource corresponding to the PUCCH format with the highest priority. Assume that PUCCH resource 1 uses PUCCH format 1 and PUCCH resource 2 uses PUCCH format 0. Since PUCCH format 0 corresponds to the highest priority, the terminal finally selects PUCCH resource 2 Transmission of HARQ-ACK information for two SPS PDSCHs.

Method 4: Assuming that PUCCH resource 1 and PUCCH resource 2 both use PUCCH format 0 and the corresponding RB resources completely overlap, the initial cyclic shift meta parameter configured by the base station for PUCCH resource 1 is 0, and the initial cyclic shift configured for PUCCH resource 2 The bit parameter is 2, it is on the corresponding RB.

Case 1: The cyclic shift value of the transmission sequence corresponding to the 2-bit HARQ-ACK transmitted by the terminal is shown in Table 2:

Case 2: The cyclic shift value of the transmission sequence corresponding to the 2-bit HARQ-ACK transmitted by the terminal is shown in Table 3:

The terminal concatenates the HARQ-ACK information corresponding to the SPS PDSCH of the two carriers in the order of ascending carrier numbers to generate a 2-bit feedback codebook, where the first bit corresponds to the HARQ-ACK information of the SPS PDSCH on carrier 1. , The second bit corresponds to the HARQ-ACK information of the SPS PDSCH on carrier 2, and then the feedback codebook is placed on the selected PUCCH resource Line transmission.

Application scenario 2: Assume that the base station configures three carriers for the terminal, and the configured K1 set is {1,2,3,4,5}. Assuming that the base station is configured for SPS PDSCH transmission on all three carriers, the HARQ-ACK of the SPS PDSCH on carrier 1 corresponds to the PUCCH resource 1 and PUCCH resource 4 configured by higher-layer signaling, and the HARQ-ACK of the SPS PDSCH on carrier 2 corresponds to the higher-layer signal. Let the configured PUCCH resource 2 and PUCCH resource 5, and the HARQ-ACK of the SPS PDSCH on carrier 3 correspond to the PUCCH resource 3 and PUCCH resource 6 configured by high-level signaling, where PUCCH resources 1~3 correspond to the PUCCH format carrying a maximum of 2 bits, PUCCH resources 4 to 6 correspond to PUCCH formats that carry more than 2 bits. In the start signaling corresponding to the SPS PDSCH on carrier 1, the HARQ feedback timing of the DCI indication is 4, and in the start signaling corresponding to the SPS PDSCH on the carrier 2, the HARQ feedback timing of the DCI indication is 5. In the start signaling corresponding to the SPS PDSCH on 3, the HARQ feedback sequence indicated by the DCI is 3.

Case 1. As shown in Figure 3, in time slot n-5 to time slot n-1, the terminal needs to receive SPS PDSCH in time slot n-5 on carrier 2 and time slot n-3 on carrier 3. The HARQ-ACK feedback of SPS PDSCH on each carrier is transmitted in time slot n. Since the number of SPS PDSCHs that need to be fed back is 2, the terminal needs to select a PUCCH resource carrying a maximum of 2 bits for feedback, that is, the terminal needs to choose to use one of PUCCH resource 1, PUCCH resource 2 and PUCCH resource 3 to transmit HARQ-ACK Feedback information. Specifically, the terminal selects PUCCH resources in the following manner.

Method 1: The terminal selects the PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number. Since the carrier 2 has the smallest number among the carriers that receive the SPS PDSCH, the terminal The PUCCH resource 2 corresponding to the SPS PDSCH transmission on carrier 2 transmits the HARQ-ACK information of the two SPS PDSCHs.

Method 2: The PUCCH resource with the latest start time among all PUCCH resources corresponding to the SPS PDSCH transmission of the terminal. Since the PUCCH resource 3 has the latest start time among the PUCCH resources corresponding to the received SPS PDSCH transmission, the terminal transmits two PUCCH resources on the PUCCH resource 3. HARQ-ACK information for each SPS PDSCH.

The terminal concatenates the HARQ-ACK information corresponding to the SPS PDSCH of carrier 2 and carrier 3 in the ascending order of the carrier number to generate a 2-bit feedback codebook, where the first bit corresponds to the HARQ of the SPS PDSCH on carrier 2. -ACK information, the second bit corresponds to the HARQ-ACK information of the SPS PDSCH on carrier 3, and then put the feedback codebook on the selected PUCCH resource for transmission.

Case 2. As shown in Figure 4, in time slot n-5 to time slot n-1, the terminal needs time slot n-4 on carrier 1, time slot n-5 on carrier 2, and time slot on carrier 3. n-3 receives the SPS PDSCH, and the HARQ-ACK feedback of the SPS PDSCH on these three carriers is transmitted in time slot n. Since the number of SPS PDSCHs that need to be fed back is 3, the terminal needs to select a PUCCH resource that carries more than 2 bits for feedback, that is, the terminal needs to choose to use one of PUCCH resource 4, PUCCH resource 5, and PUCCH resource 6 to transmit HARQ-ACK Feedback information. Specifically, the terminal selects PUCCH resources in the following manner.

Method 1: The terminal selects the PUCCH resource corresponding to the SPS PDSCH transmission with the smallest carrier number. Since the carrier 1 has the smallest number among the carriers that receive the SPS PDSCH, the terminal transmits two SPS PDSCHs on the carrier 1 corresponding to the PUCCH resource 1 for the SPS PDSCH transmission. HARQ-ACK information.

Method 2: The PUCCH resource with the latest start time among all PUCCH resources corresponding to the SPS PDSCH transmission of the terminal. Since the PUCCH resource 3 has the latest start time among the PUCCH resources corresponding to the received SPS PDSCH transmission, the terminal transmits two PUCCH resources on the PUCCH resource 3. HARQ-ACK information for each SPS PDSCH.

The terminal concatenates the HARQ-ACK information corresponding to the SPS PDSCH of carrier 1, carrier 2 and carrier 3 in the order of ascending carrier number to generate a 3-bit feedback codebook, where the first bit corresponds to the SPS on carrier 1. The HARQ-ACK information of the PDSCH, the second bit corresponds to the HARQ-ACK information of the SPS PDSCH on carrier 2, and the third bit corresponds to the HARQ-ACK information of the SPS PDSCH on carrier 3. Then put the feedback codebook in the selection Transmission on the PUCCH resource.

Application scenario 3: Assume that the base station configures three carriers for the terminal, and the configured K1 set is {1,2,3,4,5}. Assuming that the base station is configured for SPS PDSCH transmission on all three carriers, the HARQ-ACK of the SPS PDSCH on carrier 1 corresponds to the PUCCH resource 1 configured by high-level signaling, and the HARQ-ACK of the SPS PDSCH on carrier 2 corresponds to the PUCCH configured by high-level signaling Resource 2, SPS PDSCH HARQ-ACK on carrier 3 corresponds to PUCCH resource 3 configured by higher layer signaling. In the start signaling corresponding to the SPS PDSCH on carrier 1, the HARQ feedback timing of the DCI indication is 4, and in the start signaling corresponding to the SPS PDSCH on the carrier 2, the HARQ feedback timing of the DCI indication is 5. In the start signaling corresponding to the SPS PDSCH on 3, the HARQ feedback sequence indicated by the DCI is 3.

Case 1. PUCCH resources 1~3 all correspond to PUCCH formats that carry more than 2 bits. As shown in Figure 5, from time slot n-5 to time slot n-1, the terminal needs to use time slot n-5 on carrier 2. And the time slot n-3 on carrier 3 receives SPS PDSCH, and the HARQ-ACK of SPS PDSCH on these two carriers The feedback is transmitted in time slot n. Similar to the PUCCH resource determination method in the second application scenario above, the terminal can select PUCCH resource 2 or PUCCH resource 3 to transmit HARQ-ACK information, but when generating the feedback codebook, because 2 SPS PDSCHs only correspond to 2-bit HARQ -ACK feedback information, therefore, the terminal needs to add 0 at the end of the feedback information so that up to 3 bits of the feedback information are transmitted on the selected PUCCH resource.

Case 2. PUCCH resources 1~3 all correspond to the PUCCH format carrying a maximum of 2 bits. As shown in Figure 6, from time slot n-5 to time slot n-1, the terminal needs to use time slot n-4 on carrier 1. , Time slot n-5 on carrier 2 and time slot n-3 on carrier 3 receive SPS PDSCH, and the HARQ-ACK feedback of SPS PDSCH on these three carriers is transmitted in time slot n. Similar to the PUCCH resource determination method in the above application scenario 2, the terminal can choose PUCCH resource 1 or PUCCH resource 3 to transmit HARQ-ACK information, but when generating the feedback codebook, it needs to provide the HARQ-ACK feedback information corresponding to the 3 SPS PDSCHs After merging, one bit of feedback information is finally generated and transmitted on the selected PUCCH resource.

It should be noted that some embodiments of the present invention provide a HARQ-ACK feedback method for SPS PDSCH. If the terminal only needs to perform HARQ-ACK feedback for two SPS PDSCH transmissions in one time slot, it will be based on preset rules.
