Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a HARQ-ACK codebook transmission method, device and storage medium. Background Art

[0002] In order to better meet the growing demand for business types, new access technologies, such as the fifth generation mobile communication technology (5G, 5th generation mobile networks), support multicast broadcast services (MBS, Multicast and Broadcast Service) and unicast services (unicast).

[0003] In the 5G mobile communication system, in order to ensure the reliability and efficiency of data transmission, the hybrid automatic repeat request (HARQ) is adopted. The basic principle of HARQ can be understood as follows: the receiving end feeds back the decoding result of the data received from the sending end to the sending end. If the decoding is correct, the feedback is a positive confirmation (ACK), and if the decoding is not correct, the feedback is a negative confirmation (NACK). If the sending end receives ACK, it can transmit new data to the receiving end; if the sending end receives NACK, it can retransmit the data to the receiving end.

[0004] Among them, when multicast broadcast services and unicast services exist at the same time, how to effectively implement HARQ feedback is a problem that needs to be solved. Summary of the invention

[0156] The present invention will be further described in detail in conjunction with the embodiments, and the related technology will be described first.

[0157] The last downlink control information (DCI): The terminal determines the physical uplink control channel resource indicator (PRI) based on the Last DCI. PUCCH is the abbreviation for Physical Uplink Control Channel.

[0158] Figure 1 is a schematic diagram of a method for determining Last DCI; Figure 1 In the New Radio (NR) system R15 and R16, the method for determining the Last DCI includes:

[0159] Sorting all DCIs indicating the same time slot for hybrid automatic retransmission confirmation (HARQ-ACK) feedback, specifically including: first, sorting in ascending order (i.e., from first to last) according to the PDCCH monitoring occasion (MO); then, for the last PDCCH monitoring occasion after sorting, sorting in ascending order (i.e., from small to large) according to the serving cell index, and determining the Last DCI based on the sorting result. Here, the PUCCH resource indicated by the determined Last DCI is used to transmit HARQ-ACK feedback information.

[0160] In the NR system R15 and R16 versions, the method for determining the semi-static codebook (Type-1) includes:

[0161] A PDSCH reception timing set is jointly determined according to a K1 set, a frame structure, and a physical downlink shared channel (PDSCH) time domain resource allocation table (TDRA table); and a semi-static codebook is determined based on each PDSCH reception timing in the PDSCH reception timing set.

[0162] The number of HARQ-ACK bits for each PDSCH reception opportunity in the PDSCH reception opportunity set may be determined jointly based on the harq-ACK-SpatialBundlingPUCCH parameter, the maximum codeword, and the code block group (CBG) configuration parameter.

[0163] Among them, the K1 set is the time relationship between downlink data transmission and corresponding HARQ codebook feedback (Timing between DL data reception and corresponding acknowledgement); it can be fixed to {0,1,2,3,4,5,6,7,8}, or can be determined by the high-level parameter dl-DataToUL-ACK, and the high-level parameter dl-DataToUL-ACK can be any 1-8 numbers in (0, ..., 15).

[0164] like Figure 2As shown in a schematic diagram of a semi-static codebook determination method, the K1 set can be {1, 2, 3, 4}. Specifically, the K1 set can be configured by the base station as a K1 value set, such as {1, 2, 3, 4}, and sent to the terminal through RRC signaling. Subsequently, DCI is sent to the terminal to inform the terminal which of the K1 specific values ​​in the set is allocated for the data transmission. The frame structure can be: DDDUU structure.

[0165] In the NR system R15 and R16 versions, the method for determining the dynamic codebook (Type-2) includes:

[0166] Step 1: Determine the PDSCH reception timing according to the counter downlink assignment index (C-DAI) and the total downlink assignment index (T-DAI) indicated in the DCI; generate a codebook based on the determined PDSCH reception timing;

[0167] Among them, the C-DAI value represents the cumulative number of PDSCHs scheduled by DCI up to the current serving cell and the current PDCCH detection time; first sort in ascending order by serving cell index, and then sort in ascending order by PDCCH detection time;

[0168] The T-DAI value represents the total number of PDSCHs scheduled by DCI up to the current PDCCH detection timing.

[0169] The number of HARQ-ACK bits for each PDSCH reception opportunity may be determined based on the harq-ACK-SpatialBundlingPUCCH parameter and the maximum codeword;

[0170] Step 2: Place the HARQ-ACK of semi-persistent scheduling (SPS) at the end of the codebook generated above.

[0171] If CBG is enabled on some control channels (CC), the codebook is divided into two parts. The first part carries the HARQ-ACK corresponding to the PDSCH scheduled by SPS and DCI 1_0 of the CBG-enabled cell and the PDSCH scheduled by DCI 1_0 and 1_1 of the CBG-unenabled cell; the second part carries the HARQ-ACK corresponding to the PDSCH scheduled by DCI 1_1 of the CBG-enabled cell, as shown in Figure 3(b).

[0172] Regarding DAI, the number of bits is defined as follows:

[0173] 4 bits: If multiple serving cells are configured in the downlink (DL) and the higher-layer parameter pdsch-harq-ack-codebook is dynamic, the 2 most significant bits (MSB) are C-DAI and the 2 least significant bits (LSB) are T-DAI;

[0174] 2 bits: If only one serving cell is configured in DL and the higher-layer parameter pdsch-harq-cck-codebook is dynamic, 2 bits are C-DAI;

[0175] 0 bits: other cases.

[0176] FIG3(a) and FIG3(b) are schematic diagrams of a method for determining a dynamic codebook; in conjunction with FIG3(a) and FIG3(b), the method for generating a dynamic codebook is specifically described.

[0177] The base station can determine the PDSCH reception timing according to the total downlink assignment index (T-DAI) and the counter downlink assignment index (C-DAI), determine the HARQ feedback information based on the determined PDSCH reception timing, and generate a corresponding dynamic codebook.

[0179] Step 401: Multiplex a first HARQ-ACK codebook for first downlink data and a second HARQ-ACK codebook for second downlink data.

[0180] The first communication device can be a terminal, specifically a user equipment (UE), a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, or a terminal in a 5G network or a terminal in a future evolved public land mobile network (PLMN, Public Land Mobile Network), etc.

[0181] Specifically, the first communication device jointly transmits the first HARQ-ACK codebook of the first downlink data and the second HARQ-ACK codebook of the second downlink data, which may refer to the first communication device jointly sending the first HARQ-ACK codebook and the second HARQ-ACK codebook to the second communication device. The method on the second communication device side is described below Figure 7 The method is described in detail and will not be elaborated here.

[0182] In some embodiments, the first downlink data is scheduled for transmission by a physical downlink control channel (PDCCH) scrambled by a first identifier, or the first downlink data is not scheduled for transmission by the PDCCH;

[0183] The second downlink data is scheduled for transmission by a PDCCH scrambled by a second identifier.

[0184] The PDCCH scrambled by the first identifier may be a PDCCH scrambled by a cell temporary user identifier (C-RNTI, Cell Radio Network Temporary Identifier).

[0185] The PDCCH scrambled by the second identifier may be a PDCCH scrambled by a group radio network temporary identifier (G-RNTI, Group Radio Network Temporary Identifier).

[0186] In some embodiments, a first physical uplink control channel (PUCCH, Physical Uplink Control Channel) resource transmission is used to transmit the first HARQ-ACK codebook;

[0187] The second PUCCH resource transmission is used to transmit the second HARQ-ACK codebook.

[0188] In some embodiments, the first PUCCH resource and the second PUCCH resource for second service scheduling may satisfy at least one of the following conditions:

[0189] The first physical uplink control channel PUCCH resource and the second PUCCH resource are located in the same time slot;

[0190] The first PUCCH resource and the second PUCCH resource partially or completely overlap in time domain and / or frequency domain.

[0191] In some embodiments, the first HARQ-ACK codebook is a codebook for a first service, and the first service is a unicast service;

[0192] The second HARQ-ACK codebook is a codebook for a second service, and the second service is a multicast broadcast service (MBS, Multicast and Broadcast Service).

[0193] The above-mentioned first PUCCH resource and the second PUCCH resource are located in the same slot, which can be understood as the PUCCH resources for transmitting the corresponding HARQ-ACK codebooks respectively indicated by the first service and the second service are located in the same slot.

[0194] The first PUCCH resource and the second PUCCH resource partially or completely overlap in the time domain and / or frequency domain, which can be understood as the PUCCH resources for transmitting the corresponding HARQ-ACK codebooks respectively indicated by the first service and the second service partially or completely overlap in the time domain and / or frequency domain.

[0195] In some embodiments, the method further comprises:

[0196] Determine a third PUCCH resource; the third PUCCH resource is used to transmit the first HARQ-ACK codebook and the second HARQ-ACK codebook.

[0197] In some embodiments, when the first PUCCH resource and the second PUCCH resource scheduled by the second service can meet at least one of the above conditions, the method may further include:

[0198] Determine a third PUCCH resource; the third PUCCH resource is used to transmit the first HARQ-ACK codebook and the second HARQ-ACK codebook.

[0199] Figure 5 A schematic diagram of a flow chart of another HARQ-ACK codebook transmission method provided in an embodiment of the present invention; Figure 5 As shown, the HARQ-ACK codebook transmission method may include:

[0200] Step 500: Determine a third PUCCH resource;

[0201] Step 501: Use the third PUCCH resource to jointly transmit a first HARQ-ACK codebook for first downlink data and a second HARQ-ACK codebook for second downlink data.

[0202] The following two methods are specifically provided for determining the third PUCCH resource.

[0203] Method 1: Determining the third PUCCH resource includes:

[0204] For the same PDCCH monitoring timing encrypted with the first identifier and / or the PDCCH monitoring timing encrypted with the second identifier, after sorting them in ascending order according to the serving cell index (meaning sorting from small to large), sort them in ascending order according to the PDCCH monitoring timing encrypted with the first identifier and / or the PDCCH monitoring timing encrypted with the second identifier (meaning sorting from first to last), and determine the third PUCCH resource based on the sorting result.

[0205] Here, the same PDCCH monitoring timing scrambled by the first identifier and / or the PDCCH monitoring timing scrambled by the second identifier include the following situations:

[0206] The PDCCH monitoring timing of the first identifier scrambled is the same;

[0207] The PDCCH monitoring timing of the second identifier scrambled is the same;

[0208] The PDCCH monitoring timing for the first identifier scrambled is the same as the PDCCH monitoring timing for the second identifier scrambled.

[0209] Through method one, the PDCCH monitoring timing is sorted so that the second communication device side (ie, the base station side) can adjust the PUCCH resource allocation in time according to the latest scheduling situation.

[0210] Method 2, the determining of the third PUCCH resource includes:

[0211] For the PDCCH monitoring opportunities scrambled with the same first identifier, after being sorted in ascending order according to the serving cell index, the PDCCH monitoring opportunities scrambled with the first identifier are sorted in ascending order, and the third PUCCH resource is determined based on the sorting result.

[0212] Here, the PDCCH scrambled by the first identifier may be a PDCCH of a cell temporary user identifier (C-RNTI, Cell Radio Network Temporary Identifier); used for the first service, specifically a unicast service (unicast);

[0213] The PDCCH scrambled by the second identifier may be a PDCCH scrambled by a group radio network temporary identifier (G-RNTI) and is used for a second service, specifically a multicast broadcast service (MBS).

[0214] Through method 2, the DCI indicated by the PDCCH of the unicast service (unicast) is used as much as possible to determine the PUCCH resources, so that the first communication device (such as UE) in the MBS group does not need to be fully equipped with orthogonal PUCCH resources. It is only necessary to orthogonalize the PUCCH resources of the UE that needs to use the PUCCH scheduled by G-RNTI for HARQ-ACK feedback.

[0215] Figure 6 A schematic diagram of a third PUCCH resource determination method provided by an embodiment of the present invention; Figure 6 Solution 1 in the figure is the method in the first embodiment, and solution 2 is the method in the second embodiment. CC stands for control channel.

[0216] Method one or method two is used for sorting, and based on the sorting result, Last DCI is obtained, and the resource indicated by the Last DCI is the third PUCCH resource.

[0217] Specifically, the HARQ-ACK codebook includes: a first type of HARQ-ACK codebook and a second type of HARQ-ACK codebook.

[0218] The first type of HARQ-ACK codebook may specifically be a semi-static codebook;

[0219] The second type of HARQ-ACK codebook may specifically be a dynamic codebook.

[0220] For a semi-static codebook, that is, when the corresponding HARQ-ACK codebook (specifically the first HARQ-ACK codebook and the second HARQ-ACK codebook) is a first type of HARQ-ACK codebook, a method for jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook is provided.

[0221] Here, the first HARQ-ACK codebook includes first HARQ feedback information; the second HARQ-ACK codebook includes second HARQ feedback information;

[0222] The jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook specifically includes:

[0223] Determine a PDSCH reception opportunity set;

[0224] For each PDSCH reception timing in the PDSCH reception timing set, the second HARQ feedback information is placed after the first HARQ feedback information to form a third HARQ-ACK codebook.

[0225] Correspondingly, the method further includes: transmitting the constructed third HARQ-ACK codebook, so as to realize joint transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook.

[0226] Here, two bits may be reserved for each PDSCH reception opportunity, the first bit is used for unicast services, and the second bit is used for multicast broadcast services.

[0227] For the semi-static codebook, that is, when the corresponding HARQ-ACK codebook (specifically the first HARQ-ACK codebook and the second HARQ-ACK codebook) is a first type of HARQ-ACK codebook, another method for jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook is provided, specifically including:

[0228] A third HARQ-ACK codebook is generated; the third HARQ-ACK codebook includes the first HARQ-ACK codebook and a second HARQ-ACK codebook placed after the first codebook.

[0229] Correspondingly, the method further includes: transmitting the generated third HARQ-ACK codebook, so as to realize joint transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook.

[0230] The above two methods obtain the third HARQ-ACK codebook. Although the number of codebook bits will be doubled, the HARQ feedback information in the third HARQ-ACK codebook is accurate.

[0231] For the semi-static codebook, that is, when the corresponding HARQ-ACK codebook (specifically the first HARQ-ACK codebook and the second HARQ-ACK codebook) is a first type of HARQ-ACK codebook, another method for jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook is provided.

[0232] Here, the first HARQ-ACK codebook includes first HARQ feedback information; the second HARQ-ACK codebook includes second HARQ feedback information;

[0233] The method of jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook includes:

[0234] Determine a PDSCH reception opportunity set;

[0235] For each PDSCH reception opportunity in the PDSCH reception opportunity set, when there is at least one (referring to one or more) first downlink data and at least one (referring to one or more) second downlink data at the same time, the first HARQ feedback information and the second HARQ feedback information are processed using a preset rule, and a third HARQ-ACK codebook is determined according to the processing result.

[0236] Correspondingly, the method further includes: transmitting the determined third HARQ-ACK codebook, so as to realize joint transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook.

[0237] The HARQ feedback information is processed accordingly according to the preset rules, and the third HARQ-ACK codebook is obtained based on the processing result. Compared with the above two semi-static codebook determination methods, although the execution logic and processing will increase the retransmission overhead, the execution logic may affect the data reception reliability, but there is no need to increase the number of bits of the third HARQ-ACK codebook.

[0238] In actual application, a corresponding method for determining the semi-static codebook is selected based on demand, and is not limited here.

[0239] In some embodiments, the preset rule includes one of the following:

[0240] Performing a logical AND process on the first HARQ feedback information and the second HARQ feedback information;

[0241] Performing logical OR processing on the first HARQ feedback information and the second HARQ feedback information;

[0242] Target feedback information is determined based on the probabilities of ACK and NACK in the first HARQ feedback information and the second HARQ feedback information.

[0243] The logic and processing includes the following cases: {1,1}=1, {1,0}=0, {0,1}=0, {0,0}=0;

[0244] The logic or processing includes the following situations: {1,1}=1, {1,0}=1, {0,1}=1, {0,0}=0.

[0245] The corresponding "1" or "0" in the above {} is a first HARQ feedback information and a second HARQ feedback information, respectively.

[0246] The probability of ACK and the probability of NACK are determined based on the total number of the first HARQ feedback information and the second HARQ feedback information and the total number of ACKs or NACKs included therein; the probability of ACK can be understood as the proportion of ACK in the total feedback information; the probability of NACK can be understood as the proportion of NACK in the total feedback information.

[0247] Here, the determining the target feedback information based on the probabilities of ACK and NACK in the first HARQ feedback information and the second HARQ feedback information includes:

[0248] When the probability corresponding to the ACK exceeds a preset first threshold, determining the ACK as target feedback information; and / or,

[0249] When the probability corresponding to the NACK exceeds a preset second threshold, the NACK is determined as target feedback information.

[0250] That is, comparing the probability of ACK with a preset first threshold, if it exceeds the preset first threshold, determining that the corresponding HARQ feedback information in the third HARQ-ACK codebook is ACK;

[0251] Correspondingly, the probability of NACK is compared with a preset second threshold, and if it exceeds the preset second threshold, it is determined that the corresponding HARQ feedback information in the third HARQ-ACK codebook is NACK.

[0252] The first threshold and the second threshold are set by developers based on requirements.

[0253] For a dynamic codebook, that is, when the corresponding HARQ-ACK codebook (specifically the first HARQ-ACK codebook and the second HARQ-ACK codebook) is a second type of HARQ-ACK codebook, a method for jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook is provided. Specifically, the first HARQ-ACK codebook and the second HARQ-ACK codebook are jointly transmitted, including:

[0254] Receive a first DAI indicated in a PDCCH scrambled by a first identifier and a second DAI indicated in a PDCCH scrambled by a second identifier;

[0255] Determine a PDSCH reception opportunity set based on the first DAI and the second DAI;

[0256] For each PDSCH reception timing in the PDSCH reception timing set, the second HARQ feedback information is placed after the first HARQ feedback information to form a third HARQ-ACK codebook.

[0257] Here, the corresponding DAI (referring to the first DAI and the second DAI) includes at least one of the following: a counter downlink assignment index (C-DAI) and a total downlink assignment index (T-DAI).

[0258] T-DAI may be the total number of PDSCHs scheduled by the PDCCH up to the current time unit or the PDCCH monitoring opportunity.

[0259] C-DAI may be the cumulative number of PDSCHs scheduled by the PDCCH up to the current time unit or the PDCCH monitoring opportunity.

[0260] In some embodiments, the method further comprises:

[0261] The first DAI indicated in the PDCCH scrambled with the first identifier and the second DAI indicated in the PDCCH scrambled with the second identifier are counted independently.

[0262] Specifically, the PDSCH scheduled by the first service or C-RNTI is recorded as the first PDSCH, and the PDSCH scheduled by the second service or G-RNTI is recorded as the second PDSCH.

[0263] That is, the first PDSCH and the second PDSCH are counted independently.

[0264] For a dynamic codebook, that is, when the corresponding HARQ-ACK codebook (specifically the first HARQ-ACK codebook and the second HARQ-ACK codebook) is a second type of HARQ-ACK codebook, another method for jointly transmitting the first HARQ-ACK codebook and the second HARQ-ACK codebook is provided. Specifically, the first HARQ-ACK codebook and the second HARQ-ACK codebook are jointly transmitted, including:

[0265] A third HARQ-ACK codebook is generated; the third HARQ-ACK codebook includes the first HARQ-ACK codebook and a second HARQ-ACK codebook placed after the first codebook.

[0266] Figure 7 A schematic diagram of a HARQ-ACK dynamic codebook provided by an embodiment of the present invention is as follows: Figure 7 As shown, C-DAI and T-DAI are counted, and based on the counting results, the corresponding HARQ-ACK codebook is obtained.

[0270] Here, the second communication device receiving the first HARQ-ACK codebook and the second HARQ-ACK codebook jointly transmitted may refer to the second communication device receiving the first HARQ-ACK codebook and the second HARQ-ACK codebook jointly sent by the first communication device to the second communication device. Figure 4 , 5 The method is described in detail and will not be repeated here.

[0271] In some embodiments, the first downlink data is scheduled for transmission by a PDCCH scrambled by a first identifier, or the first downlink data is not scheduled for transmission by a PDCCH;

[0273] In some embodiments, a first physical uplink control channel PUCCH resource transmission is used to transmit the first HARQ-ACK codebook;

[0274] The second PUCCH resource transmission is used to transmit the second HARQ-ACK codebook.

[0275] In some embodiments, the first PUCCH resource and the second PUCCH resource scheduled by the second service meet at least one of the following conditions:

[0279] The second HARQ-ACK codebook is a codebook for a second service, and the second service is a multicast broadcast service (MBS, Multicast and Broadcast Service).

[0280] The above-mentioned first PUCCH resource and the second PUCCH resource are located in the same slot, which can be understood as the PUCCH resources for transmitting the corresponding HARQ-ACK codebooks respectively indicated by the first service and the second service are located in the same slot.
