Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a codebook generation method and device for a semi-persistently scheduled physical downlink shared channel. Background Art

[0002] In the NR downlink transmission, the base station can perform downlink data transmission by scheduling the Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS PDSCH). The SPS PDSCH is configured by the Radio Resource Control (RRC) with a transmission period and configuration index, and is activated by activating the Downlink Control Information (DCI) for periodic transmission. In the time division duplex (TDD) system, if the SPS reports, the physical uplink control channel (PUCCH) resources of the Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) may conflict with the semi-static downlink / flexible symbols configured by the RRC. In this case, the PUCCH will be discarded, causing the SPS to be unable to perform HARQ-ACK feedback, and the transmission performance will be affected. The current solution is to delay the HARQ-ACK of the conflicting SPS PDSCH to the later available PUCCH resources. When the HARQ-ACK of one or more SPS PDSCHs are delayed to the same PUCCH resource for transmission, the PUCCH resource may need to transmit the HARQ-ACK of multiple SPS PDSCHs. However, the generation of the HARQ-ACK codebook delayed to a certain PUCCH resource has not been clearly defined. Summary of the invention

For example, the first information and the second information are only used to distinguish different information, and do not indicate the difference in content, priority, sending order or importance of the two types of information.

[0029] The embodiments of the present application relate to terminal devices. The terminal device includes a device with wireless communication function, which may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in smart home, etc. The terminal device may also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, a terminal device in a future 5G network, or a terminal device in a future evolved public land mobile communication network (Public Land Mobile Network, referred to as PLMN), etc. In different networks, terminal devices may be called different names, such as: user equipment, access terminal, user unit, user station, mobile station, mobile station (Mobile Station, MS), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, cellular phone, cordless phone, Session Initiation Protocol (Session Initiation Protocol, SIP) phone, Wireless Local Loop (Wireless Local Loop, WLL) station, Personal Digital Assistant (Personal Digital Assistant, PDA), 5G network or terminal equipment in future evolution network, etc. The embodiments of the present application are not limited to this.

[0030] The network device in the embodiment of the present application can be a device for communicating with a terminal device. The network device can be a base station (Base Transceiver Station, BTS) in a GSM system or CDMA, or a base station (NodeB, NB) in a WCDMA system, or an evolved base station (evolutional nodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited.

[0031] Figure 1 Schematic diagram of the architecture of the communication system used in the embodiment of the present application. Figure 1 As shown, the network device 110 and the terminal device 120 are illustrated here by taking b=3 as an example. When the wireless communication network includes a core network, the network device 110 can also be connected to the core network. The network device 110 can also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks. The network device 110 can provide wireless access services for the terminal device 120. Each network device 110 corresponds to a service coverage area. The terminal device 120 entering the area can communicate with the network device 110 through wireless signals. In addition, the network devices 110 can also communicate with each other.

[0032] based on Figure 1 In the system architecture shown, the network device 110 schedules the SPS PDSCH for downlink transmission and indicates the time slot offset value K1 between the PDSCH and the PUCCH through the DCI. After receiving the downlink data, the terminal device 120 reports the HARQ-ACK to the network device 110 to inform the network device 110 whether it has accurately received the downlink data. When the HARQ-ACK reported by the terminal device 120 conflicts with the semi-static downlink / flexible symbol configured by the RRC, the terminal device 120 delays the conflicting HARQ-ACK to the later available PUCCH resources and generates the corresponding HARQ-ACK codebook. It should be noted that Figure 1 The form and quantity of the network device 110 and the terminal device 120 shown in the figure are for example only and do not constitute a limitation on the embodiments of the present application.

[0033] See also Figure 2 , Figure 2 A flowchart of a codebook method for semi-persistent scheduling of a physical downlink shared channel provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0034] S210. Obtain the hybrid automatic repeat request acknowledgment information HARQ-ACK of the semi-persistently scheduled physical downlink shared channel SPSPDSCH on the first physical uplink control channel PUCCH.

[0035] In actual applications, network equipment can schedule SPS PDSCH for downlink data transmission. SPS sends a physical downlink control channel (PDCCH) once, and the network equipment periodically allocates PDSCH resources to the terminal device. After each period (for example, 10ms), the terminal device uses the SPS resources to receive or send data. The SPS configuration information is configured to the terminal device by the network device through RRC signaling. After the terminal device receives the configuration information, the network device activates the SPS configuration through PDCCH, and the terminal device can receive or send data on the corresponding resources.

[0036] Among them, after the terminal device receives the downlink data sent by the network device on the PDSCH resource, it can report the HARQ-ACK of the SPS PDSCH to the network device on the PUCCH resource. HARQ-ACK may include confirmation (ACK) information and / or negative-acknowledge (NACK) information. When the downlink data is not accurately decoded, the terminal device can feedback the negative-acknowledgement information to the network device, so that the network device can determine that the terminal device has not accurately received the downlink data based on the NACK information, and can perform retransmission processing; if it can be accurately decoded, the terminal device can feedback confirmation information to the network device, so that the network device can determine that the terminal device has accurately received the data based on the ACK information, so that it can determine that the downlink data transmission is completed.

[0037] Furthermore, when SPS is transmitted, the network device can indicate the time slot offset value K1 between PDSCH and PUCCH through DCI, and the set of K1 values ​​dl-DataToUL-ACK is configured through RRC, and a value in the set is indicated by the PDSCH-to-HARQ_feedbacktiming indicator field of DCI. According to the time slot offset value K1, the terminal device can determine the PUCCH time slot for reporting the HARQ-ACK of each SPS PDSCH.

[0038] In the embodiment of the present application, the first time slot may be any time slot in the PUCCH. The time slot in the PUCCH may be divided into multiple sub-time slots, for example, 2, 4, 8, etc. The first time slot may also be any sub-time slot in any time slot of the PDCCH, which is not limited in the embodiment of the present application.

[0039] S220: When the HARQ-ACK of at least one of the SPS PDSCHs is delayed to the first time slot of the first PUCCH, determine a HARQ-ACK codebook of the SPS PDSCH in the first time slot.

[0040] Among them, in the TDD system, if the PUCCH resource reported by the terminal device for HARQ-ACK conflicts with the semi-static downlink / flexible symbol configured by RRC, the terminal device will delay the conflicting HARQ-ACK to the later available PUCCH resource. When the HARQ-ACK of at least one of the SPS PDSCHs is delayed to the first time slot of the first PUCCH, for example, Figure 3 As shown, the K1 set configured by RRC is = [2, 4, 6]. The original two SPS PDSCHs are in time slot 5 and time slot 7, respectively, and the corresponding K1 values ​​are 4 and 2, respectively. They both report HARQ-ACK in time slot 9; the SPS PDSCH in time slot 2 is delayed to report HARQ-ACK in time slot 9 due to TDD conflict, and the SPS PDSCH in time slot 4 is also delayed to report HARQ-ACK in time slot 9 due to TDD conflict, so there are 4 HARQ-ACKs that need to be reported in time slot 9. At this time, there is at least one delayed HARQ-ACK and / or at least one HARQ-ACK preconfigured by the network device in the first time slot of the first PUCCH, and the terminal device needs to determine the HARQ-ACK codebook of all SPS PDSCHs in the first time slot.

[0041] Furthermore, the HARQ-ACK codebook is a HARQ-ACK feedback sequence generated for downlink transmissions that perform HARQ-ACK feedback at the same time domain position or uplink channel. The HARQ-ACK codebook is based on time slots or sub-time slots, and the confirmation information / non-confirmation to be fed back can be jointly encoded in the same time slot or sub-time slot to generate a HARQ-ACK codebook. In the URLLC Rel-16 version, the HARQ-ACK codebook is divided into type 1 codebook and type 2 codebook, as described below:

[0042] 1. For type 1 codebook, the set of time slot offset values ​​K1 is configured by RRC signaling dl-DataToUL-ACK (corresponding to DCIformat 1_1) and / or dl-DataToUL-ACK-ForDCIFormat1_2 (corresponding to DCI format 1_2). If the terminal device monitors DCI format 1_1 and DCI format 1_2 at the same time, the set of available time slot offset values ​​K1 is determined by the union of dl-DataToUL-ACK and dl-DataToUL-ACK-ForDCIFormat1_2. For each K1 value in the time slot offset value K1 set, the HARQ-ACK codebook is generated in descending order of the K1 values. For each K1 value, the codebook size corresponding to each K1 value is determined according to the maximum number of non-overlapping PDSCH opportunities (occasion) in the pdsch-symbolAllocation table configured by RRC.

[0043] 2. For the codebook of type 2, first arrange the SPS PDSCHs in the order of their corresponding cell indices; if the cell index values ​​are the same, arrange them in the order of their corresponding time slot indices; if the time slot indices are the same, arrange them in the order of their corresponding SPS configuration indices; if the SPS configuration indices are the same, arrange them in the order of their respective transmission times. Generate the HARQ-ACK codebook according to the arrangement order of the SPS PDSCHs.

[0044] If the HARQ-ACK of the SPS PDSCH originally needs to be reported in the first delayed time slot, how to generate the HARQ-ACK codebook of the delayed PDSCH and the original codebook together?

[0045] In an embodiment of the present application, in a scenario where the HARQ-ACK of at least one SPS PDSCH is delayed to the first time slot of the first PUCCH, the terminal device determines the HARQ-ACK codebook of the SPS PDSCH in the first time slot according to the first order of the first set.

[0046] When the HARQ-ACK pre-configured with the SPS PDSCH in the first time slot needs to be reported, the terminal device reconfigures the pre-configured HARQ-ACK and the delayed HARQ-ACK to obtain a first set, and then generates a HARQ-ACK codebook according to the first order of the first set as the order of reporting HARQ-ACK.

[0047] Optionally, when the first set is a set of the SPS configuration indexes, that is, for a type 1 codebook, the first order is an order of the time slot offset values ​​in the first set from large to small.

[0048] Optionally, when the first set is a set of the SPS configuration indexes, the first order is an order in which the SPS configuration indexes in the first set are pre-configured in the SPS PDSCH time slot.

[0049] Specifically, an SPS PDSCH may be configured in the time slot, and the order of the first set is determined according to the order of the SPS configuration index of the SPS PDSCH in the time slot. For example, SPS 2 is in time slot 1 of PDSCH, SPS 3 is in time slot 2 of PDSCH, and SPS1 is in time slot 3 of PDSCH, then the order of the first set is [2,3,1].

[0050] If multiple SPS configuration indexes are pre-configured in the second time slot of the SPS PDSCH, the SPS configuration index with a smaller one is prioritized. Specifically, when multiple SPS configuration indexes are configured in a time slot, the smaller the SPS configuration index, the higher the order in the first set.

[0051] Furthermore, if the SPS configuration index in the first set is pre-configured in multiple service cells, the SPS configuration index with a smaller service cell index takes precedence. Specifically, the SPS configuration index in the service cell with a smaller service cell index is arranged in the first set in an earlier order. For example, if cell 0 has SPS 2 and SPS 1, and cell 1 has SPS 3, then the order of the first set is [2, 1, 3].

[0052] In a possible implementation manner, the first set is a set of time slot offset values ​​of the SPS PDSCH in the first time slot; or, the first set is a set of SPS configuration indexes of the SPS PDSCH in the first time slot.

[0053] Exemplarily, for the type 1 codebook, the terminal device may form the first set with the K1 set configured by RRC signaling in the first time slot and the K1 set of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot. The HARQ-ACK codebook is generated in the descending order of the K1 values ​​in the first set as the order of reporting HARQ-ACK in the first time slot. For example, Figure 4aAs shown, there are 6 SPS PDSCHs reporting HARQ-ACK in time slot 9 of PUCCH, among which the HARQ-ACK of SPS PDSCH in time slot 1 and the HARQ-ACK of SPS PDSCH in time slot 5 are configured in time slot 9 according to RRC signaling, and the K1 set configured by RRC is [4,8]; the HARQ-ACK of SPS PDSCH in time slot 2, the HARQ-ACK of SPS PDSCH in time slot 3, the HARQ-ACK of SPS PDSCH in time slot 6 and the HARQ-ACK of SPS PDSCH in time slot 7 are delayed in time slot 9 due to TDD conflict, and their K1 values ​​after delay are 7, 6, 3 and 2 respectively. Therefore, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [8,7,6,4,3,2].

[0054] Exemplarily, for the type 2 codebook, the terminal device may form the first set with the set of SPS configuration indexes configured by RRC signaling in the first time slot and the set of SPS configuration indexes of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot. The HARQ-ACK codebook is generated with the order of the SPS configuration indexes in the first set as the order of reporting HARQ-ACK in the first time slot. For example, Figure 4b As shown, there are 6 SPS PDSCHs reporting HARQ-ACK in time slot 1 of PUCCH, among which SPS PDSCH 3 on time slot 1 of serving cell 0 and SPS PDSCH 1 on time slot 5 of serving cell 0 HARQ-ACK are configured on time slot 1 according to RRC signaling; SPS PDSCH 2 on time slot 3 of serving cell 0, SPS PDSCH 4 on time slot 7 of serving cell 0, SPS PDSCH 5 on time slot 6 of serving cell 1, and SPS PDSCH 6 on time slot 6 of serving cell 1 HARQ-ACK are because TDD conflict delay occurs in time slot 1, so the order of reporting HARQ-ACK in PUCCH time slot 9 can be [3,2,1,4,5,6].

[0055] In one possible implementation, the first set includes a first subset and a second subset; the first subset is a set of time slot offset values ​​of the SPS PDSCH pre-configured by RRC signaling in the first time slot, and the second subset is a set of time slot offset values ​​of at least one of the SPS PDSCHs and a set of SPS configuration indexes of at least one of the SPS PDSCHs; or, the first subset is a set of SPS configuration indexes of the SPSPDSCH pre-configured in the first time slot, and the second subset is a set of SPS configuration indexes of at least one of the SPS PDSCHs.

[0056] When generating the HARQ-ACK codebooks for all SPS PDSCHs in the first time slot, the HARQ-ACK codebooks for the SPS PDSCHs originally present in the first time slot may be generated first, and then the HARQ-ACK codebooks for the SPS PDSCHs delayed to the first time slot may be generated.

[0057] Exemplarily, for the type 1 codebook, the first subset is the K1 set configured by RRC signaling in the first time slot, that is, the HARQ-ACK of the SPS PDSCH originally exists in the first time slot; the second subset is the K1 set of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot. The HARQ-ACK codebook is generated by taking the order of K1 values ​​in the first subset from large to small and the order of K1 values ​​in the second subset from large to small as the order of reporting HARQ-ACK in the first time slot. For example, Figure 4a As shown, the first subset is [8, 4] and the second subset is [7, 6, 3, 2], so the order of reporting HARQ-ACK in PUCCH time slot 9 can be [8, 4, 7, 6, 3, 2].

[0058] Exemplarily, for the type 2 codebook, the first subset is a set of SPS configuration indexes configured by RRC signaling in the first time slot, that is, the HARQ-ACK of the SPS PDSCH originally exists in the first time slot; the second subset is a set of SPS configuration indexes of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot. The HARQ-ACK codebook is generated by taking the order of the SPS configuration indexes in the first subset from large to small and the order of the SPS configuration indexes in the second subset from large to small as the order of reporting HARQ-ACK in the first time slot. For example, Figure 4b As shown, the first subset is [3, 1] and the second subset is [2, 4, 5, 6], so the order of reporting HARQ-ACK in PUCCH time slot 9 can be [3, 1, 2, 4, 5, 6].

[0059] At present, when the HARQ-ACK of one or more SPS PDSCHs is delayed to be transmitted in the first time slot of the first PUCCH resource, there are still many problems in the generation of the HARQ-ACK codebook in the first time slot. For example, the delayed K1 value is not within the K1 set range configured by RRC (dl-DataToUL-ACK and dl-DataToUL-ACK-ForDCIFormat1_2), or the delayed K1 value exceeds the maximum K1 value configured by RRC, or the delayed K1 value exceeds the lifetime of the service data packet.

[0060] In an embodiment of the present application, in response to the above problem, when generating a HARQ-ACK codebook, the terminal device considers the maximum K1 value configured by the RRC or the maximum generation time of the service data packet, and only generates a HARQ-ACK codebook that meets the requirements.

[0061] In one possible implementation, the first set is a set of time slot offset values ​​of the SPS PDSCH in the first time slot that satisfy a first value or a second value, the first value being the maximum time slot offset value of the SPS PDSCH pre-configured by RRC signaling in the first time slot, and the second value being the time slot offset value corresponding to the maximum survival time; or, the first set is a set of SPS configuration indexes corresponding to time slot offset values ​​of the SPS PDSCH in the first time slot that satisfy the first value or the second value.

[0062] Among them, considering the maximum K1 value configured by RRC, for the HARQ-ACK of all SPS PDSCHs in the first time slot, the terminal device only generates a HARQ-ACK codebook with a K1 value less than or equal to the maximum K1 value threshold configured by RRC, so as to ensure that the time slot offset value K1 between SPS PDSCH and PUCCH does not exceed the maximum K1 value configured by RRC, while also avoiding the problem of excessive HARQ-ACK codebook capacity.

[0063] Exemplarily, for the type 1 codebook, the terminal device combines the K1 value in the K1 set configured by RRC signaling in the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC with the K1 value in the K1 set of the SPSPDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC to form the first set. The HARQ-ACK codebook is generated in the order of reporting HARQ-ACK in the first time slot from large to small in the K1 value in the first set. For example, Figure 4a As shown, assuming that the maximum K1 value threshold configured by RRC is 6, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [6, 4, 3, 2].

[0064] Exemplarily, for the type 2 codebook, the terminal device combines the SPS configuration index corresponding to the K1 value less than or equal to the RRC configured maximum K1 value threshold in the K1 set configured by RRC signaling in the first time slot with the SPS configuration index corresponding to the K1 value less than or equal to the RRC configured maximum K1 value threshold in the K1 set of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot into the first set. The HARQ-ACK codebook is generated using the order of the SPS configuration indexes in the first set as the order of reporting HARQ-ACK in the first time slot, for example, Figure 4bAs shown, the codebook configured by RRC is [8, 4], the K1 value of SPS PDSCH2 is 6, the K1 value of SPS PDSCH 4 is 2, the K1 value of SPS PDSCH 5 and SPS PDSCH 6 is 3. Assuming that the maximum K1 value threshold configured by RRC is 6, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [2, 1, 4, 5, 6].

[0065] Among them, considering the maximum generation time of the service data packet, for the HARQ-ACK of all SPS PDSCHs in the first time slot, the terminal device only generates a HARQ-ACK codebook that is less than or equal to the K1 value corresponding to the maximum generation time, to ensure that the time slot offset value K1 between the SPS PDSCH and PUCCH does not exceed the survival time of the data packet, while also avoiding the problem of excessive HARQ-ACK codebook capacity.

[0066] Exemplarily, for the type 1 codebook, the terminal device combines the K1 value in the K1 set configured by RRC signaling in the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time and the K1 value in the K1 set of the SPSPDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time into the first set. Figure 4a As shown, assuming that the K1 value corresponding to the maximum generation time is 6, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [6, 4, 3, 2].

[0067] Exemplarily, for the type 2 codebook, the terminal device combines the SPS configuration index corresponding to the K1 value less than or equal to the K1 value corresponding to the maximum generation time in the K1 set configured by RRC signaling in the first time slot with the SPS configuration index corresponding to the K1 value less than or equal to the K1 value corresponding to the maximum generation time in the K1 set of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot into the first set. Figure 4b As shown, assuming that the K1 value corresponding to the maximum generation time is 6, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [2, 1, 4, 5, 6].

[0068] In one possible implementation, the first set includes a first subset and a second subset; the first subset is a set of time slot offset values ​​of the SPS PDSCH pre-configured by RRC signaling in the first time slot that satisfy the first value or the second value, and the second subset is a set of time slot offset values ​​of at least one of the SPS PDSCHs that satisfy the first value or the second value; or, the first subset is a set of SPS configuration indexes corresponding to time slot offset values ​​of the SPS PDSCH pre-configured by RRC signaling in the first time slot that satisfy the first value or the second value, and the second subset is a set of SPS configuration indexes corresponding to time slot offset values ​​of at least one of the SPS PDSCHs that satisfy the first value or the second value.

[0069] When generating the HARQ-ACK codebooks for all SPS PDSCHs in the first time slot, the HARQ-ACK codebooks for the original SPS PDSCHs that meet the requirements in the first time slot may be generated first, and then the HARQ-ACK codebooks for the SPS PDSCHs that meet the requirements and are delayed to the first time slot may be generated.

[0070] Exemplarily, for the type 1 codebook, considering the maximum K1 value configured by RRC, the terminal device stores the K1 value of the K1 set configured by RRC signaling in the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC in the first subset; and stores the K1 value of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC in the second subset. The HARQ-ACK codebook is generated by taking the order of K1 values ​​in the first subset from large to small and the order of K1 values ​​in the second subset from large to small as the order of reporting HARQ-ACK in the first time slot, for example, Figure 4a As shown, assuming that the maximum K1 value threshold configured by RRC is 6, the first subset is [4] and the second subset is [6,3,2]. Therefore, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [4,6,3,2].

[0071] Exemplarily, for the type 2 codebook, considering the maximum K1 value configured by RRC, the terminal device stores the SPS configuration index corresponding to the K1 value of the K1 set configured by RRC signaling in the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC in the first subset; and stores the SPS configuration index corresponding to the K1 value of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the maximum K1 value threshold configured by RRC in the second subset. For example, Figure 4bAs shown, assuming that the maximum K1 value threshold configured by RRC is 6, the first subset is [1] and the second subset is [2,4,5,6]. Therefore, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [1,2,4,5,6].

[0072] Exemplarily, for the type 1 codebook, considering the maximum generation time of the service data packet, the terminal device stores in the first subset the K1 value of the K1 set configured by RRC signaling in the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time; and stores in the second subset the K1 value of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time. The HARQ-ACK codebook is generated by taking the order of K1 values ​​in the first subset from large to small and the order of K1 values ​​in the second subset from large to small as the order of reporting HARQ-ACK in the first time slot, for example, Figure 4a As shown, assuming that the K1 value corresponding to the maximum generation time is 6, the first subset is [4] and the second subset is [6,3,2]. Therefore, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [4,6,3,2].

[0073] Exemplarily, for the type 2 codebook, considering the maximum generation time of the service data packet, the terminal device stores the SPS configuration index corresponding to the K1 value of the K1 set configured by RRC signaling in the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time in the first subset; and stores the SPS configuration index corresponding to the K1 value of the SPS PDSCH corresponding to the HARQ-ACK delayed to the first time slot that is less than or equal to the K1 value corresponding to the maximum generation time in the K1 set in the second subset. For example, Figure 4b As shown, assuming that the K1 value corresponding to the maximum generation time is 6, the first subset is [1] and the second subset is [2,4,5,6]. Therefore, the order of reporting HARQ-ACK in PUCCH time slot 9 can be [1,2,4,5,6].

[0074] In a possible implementation manner, the first set is a set of time slot offset values ​​of the SPS PDSCH pre-configured by RRC signaling in the first time slot.

[0075] Specifically, the terminal device only generates the codebook corresponding to the values ​​in the K1 set configured by RRC, and does not generate the codebook corresponding to the other K1 values.

[0076] The method of the embodiment of the present application is described in detail below by taking the K1 set configured by RRC as DataToUL-ACK=[2,4,6] as an example.

[0077] For type 1 codebook, such as Figure 5aAs shown in the figure, the SPS PDSCH on slot 5 and slot 7 upload HARQ-ACK on slot 9 according to the K1 value configured by RRC, and their corresponding K1 values ​​are 4 and 2 respectively; the SPS PDSCH on slot 2 is delayed to upload HARQ-ACK on slot 9 due to TDD conflict, and its corresponding K1 is 7; the SPS PDSCH on slot 4 is delayed to upload HARQ-ACK on slot 9 due to TDD conflict, and its corresponding K1 is 5. The K1 set corresponding to the HARQ-ACK that needs to be uploaded on slot 9 is [7,6,5,4,2]. Assume that all SPS transmission feedbacks are ACK, and each slot corresponds to only one non-overlapping PDSCH opportunity. Assume that the maximum K1 value configured by RRC is 6, and the K1 value corresponding to the maximum generation time is 6.

[0078] 1. When the HARQ-ACK codebook is generated in the order of reporting HARQ-ACK in the first time slot in descending order of the K1 values ​​of the first subset, the order of uploading HARQ-ACK is [7, 6, 5, 4, 2], and the corresponding codebook is [1, 0, 1, 1, 1].

[0079] 2. When the HARQ-ACK codebook is generated in the order of reporting HARQ-ACK in the first time slot in the order of K1 values ​​from large to small in the first subset and the order of K1 values ​​from large to small in the second subset, the order of uploading HARQ-ACK is [6, 4, 2, 7, 5], and the corresponding codebook is [0, 1, 1, 1, 1].

[0080] 3. When only the codebook corresponding to the values ​​in the K1 set configured by RRC is generated, the order of uploading HARQ-ACK is [6, 4, 2], and the corresponding codebook is [0, 1, 1].

[0081] 4. Considering the maximum K1 value configured by RRC or the maximum generation time of the service data packet, the order of uploading HARQ-ACK is [6, 5, 4, 2], and the corresponding codebook is [0, 1, 1, 1].

[0082] 5. Considering the maximum K1 value configured by RRC or the maximum generation time of the service data packet, and in the scenario where the HARQ-ACK codebook is generated in the order of K1 values ​​from large to small in the first subset and K1 values ​​from large to small in the second subset as the order of reporting HARQ-ACK in the first time slot, the order of uploading HARQ-ACK is [6, 4, 2, 5], and the corresponding codebook is [0, 1, 1, 1].

[0083] For type 2 codebook, such as Figure 5bAs shown in the figure, SPS PDSCH 3 on slot 5 of cell 0 and SPS PDSCH 4 on slot 7 of cell 0 upload HARQ-ACK on slot 9 according to the K1 value configured by RRC, and their corresponding K1 values ​​are 4 and 2 respectively; SPS PDSCH 1 on slot 2 of cell 0 is delayed to upload HARQ-ACK on slot 9 due to TDD conflict, and its corresponding K1 is 7; SPS PDSCH 2 on slot 4 of cell 0 is delayed to upload HARQ-ACK on slot 9 due to TDD conflict, and its corresponding K1 is 5; SPS PDSCH 5 and SPS PDSCH 6 on slot 7 of cell 1 are delayed to upload HARQ-ACK on slot 9 due to TDD conflict, and their corresponding K1 values ​​are both 2. The SPS configuration index corresponding to the need to upload HARQ-ACK on slot 9 is [1,2,3,4,5,6]. Assume that all SPS transmission feedbacks are ACK, and each slot corresponds to only one non-overlapping PDSCH opportunity. Assume that the maximum K1 value configured by RRC is 6, and the K1 value corresponding to the maximum generation time is 6.

[0084] 1. When the HARQ-ACK codebook is generated using the order of the SPS configuration indexes of the first subset as the order for reporting HARQ-ACK in the first time slot, the order of uploading HARQ-ACK is [1, 2, 3, 4, 5, 6], and the corresponding codebook is [0, 1, 1, 0, 1, 0].

[0085] 2. When the HARQ-ACK codebook is generated by using the SPS configuration index order in the first subset and the SPS configuration index order in the second subset as the order for reporting HARQ-ACK in the first time slot, the order of uploading HARQ-ACK is [3, 4, 5, 6, 1, 2], and the corresponding codebook is [1, 0, 1, 0, 0, 1].

[0086] 3. Considering the maximum K1 value configured by RRC or the maximum generation time of the service data packet, the order of uploading HARQ-ACK is [2, 3, 4, 5, 6], and the corresponding codebook is [1, 1, 0, 1, 0].

[0087] 4. Considering the maximum K1 value of the RRC configuration or the maximum generation time of the service data packet, and when the HARQ-ACK codebook is generated in the order of reporting HARQ-ACK in the first time slot using the SPS configuration index in the first subset and the SPS configuration index in the second subset, the order of uploading HARQ-ACK is [3, 4, 5, 6, 2], and the corresponding codebook is [1, 0, 1, 0, 1].

[0088] It can be seen that the codebook generation method for the semi-persistent scheduling physical downlink shared channel described in the embodiment of the present application, the terminal device generates the HARQ-ACK codebook according to the order from large to small of the values ​​in the actual K1 value set in the PUCCH resource or the order of the SPS configuration index in the PUCCH resource, a technical solution for determining the HARQ-ACK codebook of the SPS PDSCH on the PUCCH resource when the HARQ-ACK of at least one SPS PDSCH is delayed to the same PUCCH resource. Furthermore, the present application also considers the technical solution for generating the HARQ-ACK codebook when the delayed K1 value is not in the configured K1 set, or the K1 value may exceed the maximum value in the configured K1 set or the K1 value corresponding to the maximum lifetime.
