Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a semi-persistent scheduling (SPS) hybrid automatic repeat request acknowledgment (HARQ-ACK) processing method, device, equipment and readable storage medium. Background Art

[0002] Symbol collisions in time division duplex (TDD) systems can cause SPS HARQ-ACK to be discarded. This SPS HARQ-ACK can be understood as HARQ-ACK feedback for the SPS physical downlink shared channel (PDSCH). When the proportion of downlink or flexible symbol configurations in the frame structure is large, the probability of such a collision increases. If the network side cannot receive SPS HARQ-ACK, it can only perform blind scheduling for the corresponding SPS PDSCH, thereby reducing system efficiency, or abandon the corresponding SPS PDSCH, resulting in a large residual packet error rate, which seriously affects the transmission performance of the communication system.

[0086] In this embodiment of the present application, whether the time domain and / or frequency domain occupied by the first PUCCH resource is available is determined according to one or more of the following:

[0087] (1) Radio Resource Control (RRC) semi-static configuration;

[0088] (2) Dynamically indicated time slot format indication;

[0095] (1) Serving cell index;

[0096] (2) SPS configuration index;

[0108] In the embodiment of the present application, the foundation-based K1 set construction includes one of the following:

[0109] (1) adding an SPS HARQ-ACK bit sequence at a specified position in the codebook, wherein each HARQ-ACK bit in the SPS HARQ-ACK bit sequence corresponds one-to-one to the first SPS PDSCH, wherein no HARQ-ACK bit corresponding to the first SPS PDSCH exists in the codebook;

[0110] (2) Add X bits at a specified position in the codebook, where the X bits are used to store the HARQ-ACK corresponding to the first SPS PDSCH, wherein there is no HARQ-ACK bit corresponding to the first SPS PDSCH in the codebook, that is, the HARQ-ACK corresponding to the first SPS PDSCH does not have a corresponding HARQ-ACK bit in the codebook, and X is a positive integer.

[0111] In an embodiment of the present application, the extended K1 set construction includes one of the following:

[0112] (1) Determine the K1 values corresponding to all SPS HARQ-ACKs pointing to the time unit where the specified type 1 codebook is reported, take the union of the K1 values and the basic K1 set, sort them, and then construct the codebook based on the ordered union;

[0113] It can be understood that the basic K1 set is a basic K1 set configured by a higher layer, for example, the dl-DataToUL-ACK list of the new air interface version 15 / 16.

[0114] (2) Take the union of the K1 set used in the SPS HARQ-ACK configuration and the basic K1 set, sort them, and then construct the codebook based on the ordered union;

[0119] It can be understood that the first K1 set is the K1 set actually used when constructing the codebook, and may be equal to or different from the basic K1 set.

[0122] (2) The corresponding start and length indicator value (SLIV) is the SLIV corresponding to the second SPS PDSCH;

[0123] The second SPS PDSCH corresponds to the delayed SPS HARQ-ACK.

[0124] The type 1 codebook sets a HARQ-ACK bit sequence for a set of candidate PDSCH receptions, where each candidate PDSCH reception in the set corresponds to one or more HARQ-ACK bits in the HARQ-ACK bit sequence. The type 1 codebook can be understood to be equivalent to the HARQ-ACK bit sequence.

[0125] In an embodiment of the present application, the terminal may send a delayed SPS HARQ-ACK through the first PUCCH resource, thereby avoiding a situation where the network side cannot receive the SPS HARQ-ACK, thereby improving the reliability of the communication system.

[0126] In an embodiment of the present application, if there is a first PUCCH resource, the terminal can transmit the delayed SPS HARQ-ACK through the available first PUCCH resource, which can effectively recover the SPS HARQ-ACK discarded due to the time division duplex system symbol collision, thereby improving the reliability of the communication system.

[0171] In an embodiment of the present application, the network side device can receive the delayed SPS HARQ-ACK through the first PUCCH resource, thereby avoiding the situation where the network side cannot receive the SPS HARQ-ACK, thereby improving the reliability of the communication system.

[0172] It can be understood that the feedback of delayed SPS HARQ-ACK can include the following operations: (1) determining the available first PUCCH resource, and (2) constructing a codebook when feeding back the first SPS HARQ-ACK, wherein the first SPS HARQ-ACK includes at least: delayed SPS HARQ-ACK, which is described in detail below.

[0173] 1. Determination of the First PUCCH Resource

[0174] The function that needs to be completed by determining the first PUCCH resource is to determine which first PUCCH resource in which time unit is used to carry the feedback of the first SPS HARQ-ACK including the delay.

[0175] 1.1. Determination of time unit:

[0176] When determining the time unit where the first PUCCH resource is located, the selected first time unit is required to meet preset conditions, such as one or more of time slot conditions 1 to time slot conditions 3:

[0177] Time slot condition 1: A first PUCCH resource that meets predefined resource requirements exists within the first time unit. The predefined resource requirements include, but are not limited to, one or more of the following resource requirements 1 to 3:

[0178] (a) Resource requirement 1: The first PUCCH resource is located in a designated PUCCH resource pool.

[0179] (b) Resource requirement 2: The time and frequency (including time domain and frequency domain) occupied by the first PUCCH resource are all available. In the time domain, whether a symbol occupied by the first PUCCH resource is available can be determined based on rule 1 or rule 2:

[0180] Rule 1: Semi-static configuration based on RRC

[0181] The semi-static configuration of RRC may include: TDD configuration (Config) and / or synchronization signal block (SSB) configuration, invalid symbols, etc. Among them, the SSB transmission symbol indicated by the SSB configuration can be considered as a semi-static downlink symbol (DL symbol).

[0182] TDD Config may include: common time division multiplexing uplink and downlink configuration (TDD-UL-DL-ConfigCommon) and dedicated time division multiplexing uplink and downlink configuration (TDD-UL-DL-ConfigDedicated). For a symbol, it may indicate uplink (UL) / downlink (DL) / flexible (flexible) three states. The following rules 1-1 or 1-2 may be further adopted:

[0183] Rule 1-1: Only semi-static UL symbols are available;

[0184] Rule 1-2: Both semi-static UL symbols and semi-static flexible symbols are available.

[0185] It should be noted that when the network is configured to send a Slot Format Indication (SFI), based on the SFI indication, the Semi-static flexible symbol may be further explicitly indicated as a dynamic UL / DL / flexible symbol. For a certain Semi-static flexible symbol, when the network side is configured to send an SFI, but the terminal does not detect the SFI, or the terminal detects that the SFI further indicates this Semi-static flexible symbol as a Dynamic DL / flexible symbol, or the terminal detects that the downlink control information (DCI) schedules this Semi-static / Dynamic flexible symbol for downlink transmission (the Dynamic flexible symbol here refers to the Semi-static flexible symbol being indicated as a Dynamic flexible symbol by the SFI first), the PUCCH resource occupying this Semi-static flexible symbol will not actually be transmitted.

[0186] Therefore, when the above rule 1-1 is adopted, it can always be ensured that the determined first PUCCH resource can be actually transmitted, but it may cause the determined first PUCCH resource to be relatively late, thereby introducing a larger retransmission delay; when the above rule 1-2 is adopted, the HARQ-ACK feedback delay is smaller, but the determined first PUCCH resource may not actually be transmitted.

[0187] Optionally, for rules 1-2, when the network side is configured to send SFI but the terminal does not detect SFI, the network side can configure whether the terminal can use the Semi-static flexible symbol occupied by the first PUCCH resource as an available symbol. For example, the network side configures a high-level parameter for the terminal to indicate whether the Semi-static flexible symbol can be used for transmission of the first PUCCH resource when the terminal does not detect SFI.

[0188] Rule 2: Based on RRC semi-static configuration, such as TDD Config, SSB, etc., and dynamically indicated SFI and / or DCI.

[0189] Compared with Rule 1, it is necessary to further combine the SFI and / or DCI dynamically indicated by the physical layer to determine whether the symbol is available, thereby determining whether the entire first PUCCH resource is available.

[0190] The Semi-static UL symbol must be available. Whether the Semi-static flexible symbol is available needs to be determined based on whether the terminal is configured to detect SFI, and the further indication of the SFI detected by the terminal for this Semi-static flexible symbol. For a certain Semi-static flexible symbol, when the network side is configured to send SFI, but the terminal does not detect SFI, or the terminal detects that SFI further indicates this Semi-static flexible symbol as Dynamic DL / flexible symbol, or the terminal detects that DCI schedules this Semi-static / Dynamicflexible symbol as downlink transmission (the Dynamic flexible symbol here means that SFI first indicates this Semi-static flexible symbol as Dynamic flexible symbol), this Semi-staticflexible symbol is judged to be unavailable, and the PUCCH resource occupied by this Semi-static flexible symbol is also judged to be unavailable.

[0191] Optionally, in the time domain, when the symbols occupied by the PUCCH resource overlap with some unavailable time periods, the PUCCH resource may be considered unavailable. These unavailable time periods may include uplink / downlink switching time, bandwidth part (BWP) switching time, and unavailable time of unlicensed frequency bands (e.g., idle period in Frame Based Equipment (FBE) mode).

[0192] Optionally, from a frequency domain perspective, a PUCCH resource may be considered unavailable when the resource block occupied by the PUCCH resource conflicts with a transmission configured semi-statically by RRC. For example, a PUCCH resource may be considered unavailable when a configured Physical Random Access Channel (PRACH) or Sounding Reference Signal (SRS) transmission exists within a symbol occupied by the PUCCH resource.

[0193] Optionally, when determining whether the HARQ-ACK feedback corresponding to a certain SPS PDSCH conflicts and requires subsequent recovery, one of the above rules may be used for determination, that is, the above Rule 1 (Rule 1-1 or Rule 1-2) or Rule 2 may be used to determine whether all symbols occupied by the PUCCH transmission corresponding to the HARQ-ACK feedback corresponding to a certain SPS PDSCH are available. When at least one symbol is judged to be unavailable, a conflict occurs in this PUCCH transmission, and the HARQ-ACK corresponding to this SPS PDSCH needs to be discarded on the above PUCCH transmission and feedback is delayed.

[0194] (c) Resource requirement 3: The first PUCCH resource can carry the number of HARQ-ACK bits that need to be transmitted in the current time unit.

[0195] The number of HARQ-ACK bits that need to be transmitted in the current time unit may include, in addition to the delayed SPS HARQ-ACK feedback, the SPS HARQ-ACK feedback that needs to be fed back in the current time unit based on timing, dynamic scheduling HARQ-ACK feedback, etc.

[0196] When considering the number of bits that a PUCCH resource can carry, it is necessary to consider: the PUCCH format, the PUCCH resource set or the supported bit range, the number of occupied symbols / maximum number of physical resource blocks (PRBs) / maximum bit rate, etc.

[0197] Optionally, it is possible to consider using bundling for partially or fully delayed SPS HARQ-ACK to compress the number of HARQ-ACK bits that actually need to be transmitted, or to discard partially delayed SPS HARQ-ACK (for example, the discarding rule can be determined based on the delay time, or the SPS Config index, etc.) to reduce the number of HARQ-ACK bits that actually need to be transmitted, and to determine whether the PUCCH resource can carry the remaining HARQ-ACK bits to be transmitted based on the number of remaining HARQ-ACK bits to be transmitted after the compression or discarding operation.

[0198] It is understandable that these HARQ-ACK bits to be transmitted can be further multiplexed with other uplink control information (UCI) (such as scheduling request (SR), channel state information (CSI), etc.).

[0199] Time slot condition 2: The offset between the first time unit where the first PUCCH resource is located and the time unit where the SPS PDSCH transmission ends meets the predefined timing requirements. The predefined timing requirements here include but are not limited to timing requirement 1 and / or timing requirement 2:

[0200] Timing requirement 1: The first time unit offset does not exceed a predefined maximum value. The predefined maximum value here can include any one of maximum value method 1 to maximum value method 4:

[0201] Maximum value method 1: The maximum value of K1 in the basic K1 set configured by the higher layer (i.e., the dl-DataToUL-ACK list of NR Rel-15 / 16, hereinafter referred to as the basic K1 set);

[0202] Maximum value mode 2: The TDD cycle length corresponding to the TDD Pattern configured by the higher layer. The TDD Pattern here can be the information configured in TDD-UL-DL-ConfigCommon, such as pattern1 and pattern2.

[0203] Maximum value mode 3: Parameters independently configured by the upper layer;

[0204] Maximum value method 4: the value specified in the protocol.

[0205] Timing requirement 2: The time unit offset is a value from a predefined set. The predefined set can include any of set types 1 to 4:

[0206] Collection method 1: Basic K1 set;

[0207] Set 2: New K1 set configured independently by the higher layer for delayed SPS HARQ-ACK;

[0208] Collection mode 3: The union of the additional K1 set configured by the higher layer for delayed SPS HARQ-ACK and the basic K1 set;

[0209] Collection method 4: The collection specified in the protocol.

[0210] Time slot condition 3: the earliest time unit in a set of time units that satisfy one or more other time slot conditions (ie, satisfy time slot condition 1, or satisfy both time slot condition 1 and time slot condition 2).

[0211] 1.2. Selection of the first PUCCH resource

[0212] When determining the first PUCCH resource for carrying delayed SPS HARQ-ACK, it is necessary to first determine the range of available resources, that is, the PUCCH resource pool, and then further select the first PUCCH resource in the PUCCH resource pool.

[0213] 1.2.1 Determination of PUCCH Resource Pool

[0214] The PUCCH resource pool may be determined by one or more resource pools from resource pool 1 to resource pool 3 (when multiple resource pools are involved, the union of the PUCCH resource sets corresponding to these resource pools is taken):

[0215] Resource pool 1: PUCCH resources in the PUCCH resource set configured for dynamic scheduling of HARQ-ACK feedback;

[0216] Resource pool 2: PUCCH resource or PUCCH resource list independently configured for HARQ-ACK transmission containing only SPS HARQ-ACK (i.e., SPS HARQ-ACK only), including a single PUCCH resource configured by the n1PUCCH-AN parameter in SPS-Config (corresponding to PUCCH format 0 / 1), and a PUCCH resource list configured by the sps-PUCCH-AN-List-r16 parameter in PUCCH-Config;

[0217] Resource pool 3: independently configured PUCCH resources that can be used for SPS HARQ-ACK feedback (including delayed SPS HARQ-ACK). These PUCCH resources can appear periodically.

[0218] It should be noted that, based on the current protocol, when SPS HARQ-ACK is transmitted independently (i.e., SPS HARQ-ACK only), the PUCCH resource in resource pool 2 is used; when SPS HARQ-ACK is multiplexed with dynamically scheduled HARQ-ACK, the PUCCH resource in resource pool 1 is used. However, when the PUCCH resource pool here is the union of resource pool 1 and resource pool 2, it can be understood that even if only SPS HARQ-ACK is transmitted, the PUCCH resource in the PUCCH resource set corresponding to resource pool mode 1 can also be used.

[0219] 1.2.2. Selection of the first PUCCH resource in the PUCCH resource pool

[0220] The aforementioned predefined resource requirements can be considered as the basic requirements for selecting a PUCCH resource. There may be more than one first PUCCH resource that meets the predefined resource requirements and is located in the determined first time unit. In this case, the first PUCCH resource can be determined based on any one of the following selection methods 1 to 3:

[0221] Selection method 1: Select the first PUCCH resource with the earliest time. This can minimize the HARQ-ACK feedback delay. The first PUCCH resource time can be any of the following:

[0222] (a) The start time of the first PUCCH resource;

[0223] (b) the end time of the first PUCCH resource;

[0224] Selection method 2: Select the first PUCCH resource corresponding to PRI.

[0225] This is primarily for situations where the PUCCH resource pool includes a PUCCH resource in resource pool 1. The PRI can be the PRI indicated in the activation / reactivation DCI. When selecting a PUCCH resource, resource requirement 1 of the predefined resource requirements must be met. Resource requirement 3 can be met when selecting the PUCCH resource set in resource pool 1, and resource requirement 2 can be met when determining the time unit. This means searching backwards until a time unit that meets the requirements is found or the SPS HARQ-ACK is discarded due to exceeding the maximum latency limit.

[0226] When the SPS HARQ-ACK to be transmitted corresponds to multiple SPS Configs, and at least two of the multiple SPS Configs correspond to different PRIs, it is necessary to select the PRI or PUCCH resource corresponding to the SPS HARQ-ACK. Any of the following PRI modes 1 to PRI mode 3 can be used:

[0227] PRI mode 1: select PRI based on the serving cell index (Serving cell index) and / or the SPS configuration index (SPSConfig index).

[0228] The PRI corresponding to the SPS Config with the smallest / largest / specified SPS Config index and / or the corresponding Serving cell index among multiple SPS Configs can be used. For example, the PRI corresponding to the SPS Config with the smallest Serving cell index and the smallest SPS Config index can be used to select the PUCCH resource.

[0229] PRI mode 2: PRI is selected based on the transmission time of the SPS PDSCH.

[0230] The PRI corresponding to the SPS Config corresponding to the SPS PDSCH with the earliest / latest / specified transmission time in the SPS PDSCH set corresponding to the SPS HARQ-ACK to be transmitted can be used. The SPS PDSCH transmission time here can be the start time or end time of the SPS PDSCH. For example, the PRI corresponding to the SPSConfig corresponding to the SPS PDSCH with the earliest start time can be used to select the first PUCCH resource.

[0231] PRI mode 3: Select the first PUCCH resource based on the capacity of the PUCCH resource.

[0232] Based on the multiple PRIs corresponding to the multiple SPS Configs, the PUCCH resource corresponding to each PRI can be determined to obtain a PUCCH resource subset. The PUCCH resource in this PUCCH resource subset with the minimum / maximum / specified capacity or the most matching number of SPS HARQ-ACK bits to be transmitted (e.g., the absolute value of the difference between the two is the smallest) is selected.

[0233] It is understood that when SPS HARQ-ACK is multiplexed with dynamic scheduling HARQ-ACK, the PRI indicated by the dynamic scheduling can be used to determine the PUCCH resource. For example, the PRI indicated in the last dynamic scheduling DCI corresponding to the HARQ-ACK codebook obtained by multiplexing the two can be used to determine the PUCCH resource.

[0234] Selection method 3: Select the first PUCCH resource that can carry the largest number of bits.

[0235] For factors that need to be considered in determining the number of bits that the first PUCCH resource can carry, refer to the corresponding description in resource requirement 3.

[0236] 2. Handling Resource Determination Failure

[0237] Based on the aforementioned corresponding scheme, the terminal may not be able to successfully determine the first PUCCH resource. For example, the UE may not be able to successfully select a time unit that meets one or more specified conditions, or the first PUCCH resource corresponding to the PRI and meeting the predefined resource requirements does not exist in the selected time unit.

[0238] When the UE cannot successfully determine the first PUCCH resource, it can adopt either of the following processing methods 1 and 2:

[0239] Solution 1: The network side subsequently triggers SPS HARQ-ACK retransmission.

[0240] At this point, it can be considered that the solution of delaying HARQ-ACK feedback to the next available PUCCH is no longer applicable. The delayed SPS HARQ-ACK may be discarded by the network, or the network may trigger the retransmission of the corresponding SPS HARQ-ACK based on dynamic signaling or other methods as needed. For example, the network side instructs the UE to use the Type-3 codebook or an enhanced / optimized Type-3 codebook based on DCI to retransmit part or all of the delayed SPS HARQ-ACK.

[0241] Processing method 2: The UE compresses the delayed SPS HARQ-ACK or discards part of the SPS HARQ-ACK.

[0242] The UE may adopt a Bundling method for partially or fully delayed SPS HARQ-ACK to compress the number of HARQ-ACK bits that actually need to be transmitted, or may discard partially delayed SPS HARQ-ACK (for example, the discarding rule may be determined based on the delay time, or the SPS Config index, etc.) to reduce the number of HARQ-ACK bits that actually need to be transmitted, and re-determine the PUCCH resource based on the remaining number of HARQ-ACK bits to be transmitted obtained after the compression or discarding operation. The PUCCH resource re-determination operation here may be only for the last one or more time units within the allowed delay time range, or for each time unit within the allowed delay time range.

[0243] The following describes an optional first PUCCH resource determination process:

[0244] Step 1: For the currently delayed SPS HARQ-ACK, determine whether the current time unit meets time slot condition 2. If so, execute step 2; otherwise, if it is determined that time slot condition 2 is no longer possible to meet in the future (for example, when considering timing requirement 1 and the time unit offset has exceeded the predefined maximum value, or when considering timing requirement 2 and all values in the predefined set have been tried and none of them meet the requirements), exit the current process and apply the aforementioned failure handling related operations. Otherwise, further execute step 1 in the next time unit; Note that time slot condition 3 is already reflected in the process of finding time units that meet other time slot conditions and does not need to be considered separately;

[0245] Step 2: Determine the number of HARQ-ACK bits that need to be transmitted in the current time unit, which may include delayed SPS HARQ-ACK, SPS HARQ-ACK that needs to be fed back in the current time unit based on timing, dynamic scheduling HARQ-ACK feedback, etc.

[0246] Step 3: Based on the HARQ-ACK bits that need to be transmitted (the output of step 2, mainly involving the number of HARQ-ACK bits, the downlink transmission / indication corresponding to HARQ-ACK, etc.), determine the PUCCH resource pool. Based on the various PUCCH resources located in the PUCCH resource pool in the current time unit, determine whether there are one or more PUCCH resources that meet the predefined resource requirements, and also determine whether the current time unit meets time slot condition 1. When it is determined that there are one or more PUCCH resources that meet the predefined resource requirements in the current time unit (at this time, the current time unit also meets time slot condition 1), the first PUCCH resource is selected based on a certain selection method for transmitting HARQ-ACK information; otherwise, continue with step 1. When selection method 2 is adopted and there is no first PUCCH resource corresponding to PRI, it can be considered an ErrorCase (required to be avoided based on implementation), or step 1 can be continued.

[0247] After the first PUCCH resource is determined in step 3, the HARQ-ACK codebook constructed based on the HARQ-ACK codebook construction scheme described below can be carried on the determined first PUCCH resource.

[0248] Note that the construction time of the HARQ-ACK codebook can be explicitly specified or determined based on the implementation of the terminal. For example, the corresponding HARQ-ACK codebook can be constructed when the number of HARQ-ACK bits is determined in step 2, or the corresponding HARQ-ACK codebook can be constructed after the first PUCCH resource is determined in step 3 to avoid unnecessary HARQ-ACK codebook construction. When the determined first PUCCH resource overlaps with PUSCH or PUCCH, various multiplexing rules in the existing specifications can be further applied.

[0249] The above first PUCCH resource determination process is used as an example. A simple conditional judgment is first performed on the time unit, and then the first PUCCH resource that meets the requirements within the time unit is judged / selected to reduce the complexity of the terminal.

[0250] Optionally, the first PUCCH resource that meets the requirements can be determined based on the HARQ-ACK bit within a certain time unit (for example, first execute steps 2 and 3 above), and then determine whether this time unit meets the corresponding conditions (for example, execute step 1 above again). If not, continue to perform the corresponding operations for the next time unit until the first time unit and the first PUCCH resource combination that meet the requirements / conditions are found, or the search cannot be continued and the determination process is exited, and the relevant operations for failure processing are applied.

[0251] 3. HARQ-ACK Codebook Construction

[0252] Based on the HARQ-ACK bits that need to be transmitted (including the PDSCH transmission type corresponding to these HARQ-ACK bits), the codebook categories are described as follows:

[0253] (1) Category 0: SPS HARQ-ACK only

[0254] The construction of the codebook can follow the existing codebook construction process, that is, according to the three-layer loop of serving cell (Serving cell)-SPS configuration index (Config index)-downlink time slot (DL slot) (i.e., SPS PDSCH), first traverse the DL slots / SPS PDSCHs corresponding to a certain SPS Config index of a certain Serving cell, then traverse the various SPS Config indexes of a certain Serving cell, and finally traverse the various Serving cells configured for the terminal. It should be noted that the loop range of SPS PDSCH has been expanded at this time. It is no longer limited to the SPS PDSCH corresponding to a certain SPS Config and whose end time falls in the same UL slot (corresponding to time unit n in HARQ timing), but needs to consider all delayed HARQ-ACK feedback of this SPS Config (still satisfying the aforementioned time slot condition 2) and the SPS HARQ-ACK that needs to be fed back within a certain time unit based on the timing (time unit n+k).

[0255] Optionally, the loop order of the three dimensions of Serving cell, SPS Config index, and DL slot can also be adjusted to execute each layer of loop in another order. For example, the three-layer loop of Serving cell-DL slot-SPS Configindex can be performed, first traversing the SPS PDSCH corresponding to each SPS Config index in a certain Serving cell in a certain DL slot (or, traversing one or more SPS PDSCHs corresponding to each SPS Config index in this DL slot uniformly according to the start / end time of the SPS PDSCH), then traversing each DL slot of the SPS PDSCH on a certain Serving cell where there is a HARQ-ACK to be fed back, and finally traversing each Serving cell configured for the UE.

[0256] (2) Category 1: Type-1 codebook

[0257] This can be considered in conjunction with the aforementioned time slot condition 2. Based on the K1 set based on the Type-1 codebook construction, two types of solutions can be distinguished: codebook solution 1 and codebook solution 2:

[0258] 2.1 Codebook solution 1: always based on the basic K1 set

[0259] At this time, the construction of the Type-1 codebook and the correspondence between each HARQ-ACK bit in the codebook (the codebook here refers to the HARQ-ACK bit sequence determined by the predefined pseudo-code process, the same below) and the candidate PDSCH reception (Candidate PDSCHreception) are determined based on predefined rules. For example, the above-mentioned codebook includes the HARQ-ACK bits corresponding to any SLIV that can be scheduled by the network side for any K1 in the basic K1 set. These HARQ-ACK bits are cascaded into a HARQ-ACK bit sequence based on the predefined pseudo-code process, and the correspondence between each HARQ-ACK bit and the candidate PDSCH reception is determined. When the SPS PDSCH corresponding to the delayed SPS HARQ-ACK cannot find the corresponding HARQ-ACK bit in the codebook, the following codebook method 1-1 or codebook method 1-2 can be used:

[0260] (a) Codebook method 1-1: At a specified position in the Codebook, such as the head or the tail, add the corresponding SPS HARQ-ACK bit sequence. Each HARQ-ACK bit in the sequence corresponds to an SPS PDSCH that does not have a corresponding HARQ-ACK bit in the Codebook. The specific construction process of the added SPS HARQ-ACK bit sequence can refer to the construction process in Category 0, but those SPS PDSCHs that have corresponding HARQ-ACK bits in the Codebook will be skipped.

[0261] This method may not be able to guarantee the characteristics of the semi-static Codebook size because the length of the added HARQ-ACK bit sequence may change with the number of delayed SPS HARQ-ACK bits and the correspondence between the SPS PDSCHs with delayed HARQ-ACK feedback and the Candidate PDSCH reception of the Codebook. As a result, the number of all HARQ-ACK bits to be fed back is unstable, and there may be a risk of inconsistent understanding of the number of HARQ-ACK bits fed back on both sides (when Resource Requirement 2 adopts Rule 2 and the Downlink Control Information Format 2_0 (DCI format 2_0) carrying the dynamic SFI is missed at the terminal side).

[0262] (b) Codebook method 1-2: At a specified position in the Codebook, such as the head or the tail, add X bits to store the HARQ-ACK corresponding to the SPS PDSCH that does not have a corresponding HARQ-ACK bit in the Codebook. X can be semi-statically configured by higher-layer signaling or clearly defined in the protocol.

[0263] The occupation of the X bits can refer to the setting of the added HARQ-ACK bit sequence (assumed to be Y bits) in Codebook method 1-1: When X >= Y, the correspondence and values of the first Y bits in the X bits with the SPS PDSCH are exactly the same as those of the added HARQ-ACK bit sequence in Codebook method 1-1, and the last X - Y bits can be set to a default value, such as NACK; when X < Y, the correspondence and values of the X bits with the SPS PDSCH are exactly the same as the first X bits of the added HARQ-ACK bit sequence in Codebook method 1-1. At this time, Y - X bits of SPS HARQ-ACK are discarded. X and Y are natural numbers.

[0264] Optionally, when determining X, the UE expects to avoid the situation where such SPS HARQ-ACK is discarded (the network side avoids it during configuration).

[0265] 2.2. Codebook scheme 2: Expand K1 set

[0266] In conjunction with the aforementioned predefined timing requirements, the K1 set used to construct the Type-1 codebook is expanded from the base K1 set. Because the Type-1 codebook is only required when SPS HARQ-ACK is multiplexed with dynamically scheduled HARQ-ACK, the K1 set used to construct the Type-1 codebook must include all values in the base K1 set to avoid impacting dynamic scheduling.

[0267] Optionally, codebook scheme 2 includes: codebook mode 2-1 and codebook mode 2-2.

[0268] (a) Codebook approach 2-1: Determine the extension of the K1 set based on each Type-1 codebook (the K1 used by the SPSHARQ-ACK is indicated by the activation / reactivation DCI). That is, determine the K1 values corresponding to all SPS HARQ-ACKs reporting in the time slot of a certain Type-1 codebook, take the union of these K1 values with the basic K1 set, and sort them in a predefined manner. Based on the ordered K1 union, the Rel-15 Type-1 codebook construction process is continued.

[0269] The predefined sorting method here can be descending order from small to large, or other sorting methods.

[0270] (b) Codebook method 2-2: The K1 set based on which the Type-1 codebook is constructed is determined based on high-layer signaling or protocol specifications. Either of the following codebook methods 2-2-1 and 2-2-2 can be further adopted:

[0271] -Codebook method 2-2-1: Take the K1 set used by the SPS HARQ-ACK configuration (see the various methods in the predefined set above), take the union of it with the basic K1 set (if the K1 set used by the SPS HARQ-ACK configuration is the basic K1 set, or has already been taken as a union with the basic K1 set, then there is no need to take the union here), and sort it according to the predefined method. Based on the ordered K1 union, the existing Type-1 codebook construction process is used.

[0272] The predefined sorting method here can be descending order from small to large, or other sorting methods.

[0273] -Codebook method 2-2-2: Expand the K1 set to include all natural numbers from 0 to the maximum value of K1, and sort them in a predefined way. Based on the ordered K1 expansion set and following the existing Type-1 codebook construction process.

[0274] The predefined sorting method here can be descending order from small to large, or other arrangements. The maximum value of K1 here can be the larger value of the aforementioned predefined maximum value and the maximum value in the basic K1 set. The main consideration here is that multiple SPS Configs can be configured for a single UE, and the minimum period of each SPS Config can be a single time slot. In this case, there may be an SPS PDSCH in each (downlink) time slot, or there may be an SPSHARQ-ACK that requires feedback in each (uplink) time slot.

[0275] Optionally, in order to avoid adding new HARQ-ACK bits in the Type-1 codebook due to the extension of the K1 set, the Type-1 codebook is constructed based on the extended K1 set only when delayed SPS HARQ-ACK needs to be multiplexed in a certain Type-1 codebook. Otherwise, the Type-1 codebook is constructed only based on the basic K1 set configured by the higher layer.

[0276] It can be understood that when the delayed SPS HARQ-ACK corresponds to a K1 in the Type-1 codebook construction process (ie, for the above codebook scheme 1, a K1 in the basic K1 set, for the above codebook scheme 2, a K1 in the extended K1 set), the candidate PDSCH reception corresponding to the delayed SPS HARQ-ACK satisfies both (a) and (b):

[0277] (a) The corresponding K1 is the offset between the time slot where the SPS PDSCH ends and the Type-1 codebook feedback time slot;

[0278] (b) The corresponding SLIV is the SLIV of SPS PDSCH.

[0279] (3) Category 2: Type-2 codebook

[0280] The SPS HARQ-ACK sequence at the end of the codebook needs to include the HARQ-ACK feedback from each SPS Config delayed to the current time unit. For details, please refer to the operation of Category 0.

[0281] In addition, the processing of the enhanced dynamic codebook is similar to that of the Type-2 codebook and will not be repeated here.

[0282] In the embodiment of the present application, the SPSHARQ-ACK discarded due to TDD system symbol collision is transmitted through the available PUCCH resources to ensure the smooth operation of the functions of all relevant links of the system, thereby ensuring the overall performance of the system
