[0026] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0027] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0028] In the subsequent description, suffixes such as "module," "component," or "unit" used to represent elements are used only to facilitate the description of the present application and have no specific meaning. Therefore, "module," "component," or "unit" may be used interchangeably.

[0029] FIG1 is a flow chart of a HARQ-ACK generation method provided in an embodiment of the present application. The method may be performed by a user equipment (UE). As shown in FIG1 , the method includes the following steps:

[0030] S110, receiving at least one of the first information, the second information, and the third information.

[0031] S120: Determine the HARQ-ACK received in the downlink (DL) based on the information obtained based on at least one of the first information, the second information, and the third information according to the agreed rule.

[0032] Among them, DL reception includes at least one of the following: semi-persistent scheduling (SPS) configuration, physical downlink shared channel (PDSCH) scheduled based on downlink control information (DCI), PDSCH with repetitions, multiple PDSCHs scheduled by a single DCI, periodic or semi-persistent channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), periodic physical downlink control channel (PDCCH); based on the first information, at least one of the following is obtained: orthogonal frequency division multiplexing (OFDM) symbol position of DL reception, frequency domain resource position of DL reception, slot (time slot) position of DL reception; based on the second information, at least one of the following is obtained: position of first type OFDM symbol, position of first type slot, resource position of first type resource; based on the third information, at least one of the following is obtained: transmission mode of DL reception.

[0033] The position of the OFDM symbol may include the symbol index and quantity.

[0034] In an embodiment of the present application, the first type of resources includes a subband full duplex (SBFD) subband or a co-frequency co-time full duplex (CCFD) subband, and the SBFD subband or CCFD subband is configured in a DL OFDM symbol or a flexible OFDM symbol; the SBFD subband includes a UL subband and a DL subband; the first type of OFDM symbol refers to an OFDM symbol configured with the first type of resources, and the second type of OFDM symbol refers to an OFDM symbol not configured with the first type of resources; the first type of slot includes a slot configured with the first type of OFDM symbol, and the second type of slot includes a slot not configured with the first type of OFDM symbol.

[0035] SBFD technology was proposed to improve uplink (UL) coverage, UL latency, and UL capacity in time division duplex (TDD) systems. A UL subband can be configured in a downlink (DL) symbol / DL slot and an F symbol / F slot. UL subbands are configured based on resource blocks (RBs). Symbols configured with an SBFD subband are called SBFD symbols, and slots containing SBFD symbols are called SBFD slots. Symbols not configured with an SBFD subband are called non-SBFD symbols (i.e., regular symbols), and slots that do not contain an SBFD symbol are called non-SBFD slots.

[0036] For repetitive or periodic UL transmission and DL reception, if the UE knows the SBFD symbol / slot configuration, the following transmission modes can be supported:

[0037] Option 1: UL transmission / DL reception is performed only in SBFD symbols or only in non-SBFD symbols. That is, all UL transmission / DL reception of a UL transmission / DL reception is performed only in SBFD symbols or only in non-SBFD symbols. For example, the first UL transmission / DL reception of a UL transmission / DL reception is performed in a symbol of a certain type (e.g., SBFD symbols or non-SBFD symbols), and the second UL transmission / DL reception is performed in a symbol of the same type.

[0038] Option 2: UL transmission / DL reception can be performed in both SBFD symbols and non-SBFD symbols. This means that different UL transmissions / DL receptions can be performed in both SBFD symbols and non-SBFD symbols for the same UL transmission / DL reception. For example, the first UL transmission / DL reception of a UL transmission / DL reception is performed in an SBFD symbol (or non-SBFD symbol), and the second UL transmission / DL reception is performed in a non-SBFD symbol (or SBFD symbol).

[0039] Furthermore, the above option 1 can be divided into two options:

[0040] Option 1-1: UL transmission / DL reception is performed only in SBFD symbols. This means that all UL transmission / DL receptions for a UL transmission / DL reception are performed only in SBFD symbols. For example, if the first UL transmission / DL reception for a UL transmission / DL reception is performed in an SBFD symbol, the second UL transmission / DL reception is also performed in an SBFD symbol.

[0041] Option 1-2: UL transmission / DL reception is performed only in non-SBFD symbols. That is, all UL transmission / DL reception of a UL transmission / DL reception is performed only in non-SBFD symbols. For example, if the first UL transmission / DL reception of a UL transmission / DL reception is performed in a non-SBFD symbol, the second UL transmission / DL reception is also performed in a non-SBFD symbol.

[0042] The above-mentioned UL transmission and DL reception include at least one of the following: PDSCH / PUSCH / PUCCH repetition, SPS PDSCH / CG PUSCH, TBoMS, multiple PUSCH / PDSCH scheduled by a single DCI, periodic / semi-persistent SRS / CSI-RS / PUCCH or PDCCH.

[0043] In one embodiment, FIG2 is an example diagram of a transmission mode. As shown in FIG2 , assuming that the above-mentioned DL reception is an SPS configuration, the above-mentioned transmission mode is illustrated based on the SPS configuration.

[0044] In Figure 2, the periodic position of the SPS configuration with index 1 is shown in the figure. If the SPS configuration is executed based on option 1-1, then in the 5th slot, the SPS PDSCH of the SPS configuration cannot be executed because the symbol type of the SPS PDSCH is a non-SBFD symbol, that is, in the 5th slot, the symbol corresponding to the SPS PDSCH is not the symbol type required by the SPS configuration.

[0045] In Figure 2, the periodic position of the SPS configuration with index 0 is shown in the figure. If the SPS configuration is executed based on option 1-2, then in the 2nd and 6th slots, the SPS PDSCH of the SPS configuration cannot be executed because the symbol type of the SPS PDSCH is the SBFD symbol, that is, in the 2nd and 6th slots, the symbol corresponding to the SPS PDSCH is not the symbol type required by the SPS configuration.

[0046] In Figure 2, the periodic position of the SPS configuration with index 2 is shown in the figure. If the SPS configuration is executed based on option 2, then the SPS PDSCH of the SPS configuration can be executed in the 1st, 3rd, 5th and 7th slots, that is, in the 1st, 3rd and 7th slots, the SPS PDSCH of the SPS configuration can be executed in the SBFD symbol, and in the 5th slot, the SPS PDSCH of the SPS configuration can be executed in the non-SBFD symbol.

[0047] Based on the above introduction, in order to further improve system efficiency and spectrum efficiency, this application proposes co-frequency co-time full duplex (CCFD) operation. First, the configuration of CCFD resources is proposed:

[0048] Within a carrier, the base station configures an RB set based on contiguous RBs in the frequency domain for CCFD operations, and also configures certain slots or symbols in the time domain for CCFD operations based on symbols or slots. This provides some time-frequency resources (denoted as Resource A) for CCFD operations. At least from the base station's side, Resource A can be used for simultaneous full-duplex transmission on the same frequency. That is, the base station can simultaneously transmit downlink signals and receive uplink signals in Resource A using the same time and frequency.

[0049] In this application, symbols / slots configured with resource A are referred to as CCFD symbols / slots, and symbols / slots not configured with resource A are referred to as non-CCFD symbols / slots (e.g., regular symbols / slots). For example, FIG3 is an example diagram of time-frequency resources for CCFD operation in an embodiment of this application.

[0050] Due to the different channel interference environments in CCFD symbols and non-CCFD symbols, there is a significant performance difference between UL transmission / DL reception in CCFD symbols / slots and UL transmission / DL reception in non-CCFD symbols / slots. Therefore, the following transmission mode is introduced to support repetitive or periodic DL transmission and DL reception.

[0051] Option 1A: UL transmission / DL reception is performed only in CCFD symbols or non-CCFD symbols. This means that all UL transmission / DL receptions in a UL transmission / DL reception are performed only in CCFD symbols or only in non-CCFD symbols. For example, the first UL transmission / DL reception in a UL transmission / DL reception is performed in a symbol of a certain type (e.g., CCFD symbols or non-CCFD symbols), and the second UL transmission / DL reception is performed in the same symbol type.

[0052] Option 2A: UL transmission / DL reception can be performed in both CCFD symbols and non-CCFD symbols. This means that different UL transmissions / DL receptions within a single UL transmission / DL reception can be performed in both CCFD symbols and non-CCFD symbols. For example, the first UL transmission / DL reception within a single UL transmission / DL reception can be performed in a CCFD symbol (or non-CCFD symbol), while the second UL transmission / DL reception can be performed in a non-CCFD symbol (or CCFD symbol).

[0053] Furthermore, option 1A can be divided into two options:

[0054] Option 1A-1: UL transmission / DL reception is performed only in CCFD symbols. This means that all UL transmission / DL receptions for a UL transmission / DL reception are performed only in CCFD symbols. For example, if the first UL transmission / DL reception for a UL transmission / DL reception is performed in a CCFD symbol, the second UL transmission / DL reception is also performed in a CCFD symbol.

[0055] Option 1A-2: UL transmission / DL reception is performed only in non-CCFD symbols. This means that all UL transmission / DL receptions for a UL transmission / DL reception are performed only in non-CCFD symbols. For example, if the first UL transmission / DL reception for a UL transmission / DL reception is performed in a non-CCFD symbol, the second UL transmission / DL reception is also performed in a non-CCFD symbol.

[0056] The above-mentioned UL transmission and DL reception include at least one of the following: PDSCH / PUSCH / PUCCH repetition, SPS PDSCH / CG PUSCH, TBoMS, multiple PUSCH / PDSCH scheduled by a single DCI, periodic / semi-persistent SRS / CSI-RS / PUCCH or PDCCH.

[0057] In this application, semi-persistent PDSCH (SPS PDSCH) transmission is used as an example to describe the channel / signal configuration method and the corresponding reception method based on SBFD or CCFD. It is also applicable to the channel / signal configuration method and the corresponding reception method based on CCFD. It can be applied to other channels, such as PDSCH / PUSCH / PUCCH repetitions, CG PUSCH, TBoMS, Multi-PUSCH / PDSCH scheduled by a single DCI, Periodic / semi-persistent SRS / CSI-RS / PUCCH, PDCCH.

[0058] The following method is described mainly focusing on transmission / reception based on SBFD subbands. It can also be applied to transmission / reception based on CCFD, for example, by replacing SBFD symbols / slots with CCFD symbols / slots, and by replacing non-SBFD symbols / slots with non-CCFD symbols / slots.

[0059] Correspondingly, the SBFD-based transmission mode can also be replaced by the CCFD-based transmission mode, for example, by replacing the above-mentioned option 1 with the above-mentioned option 1A, by replacing the above-mentioned option 2 with the above-mentioned option 2A, by replacing the above-mentioned option 1-1 with the above-mentioned option 1A-1, and by replacing the above-mentioned option 1-2 with the above-mentioned option 1A-2.

[0060] In one embodiment, the manner in which the HARQ-ACK received by the downlink DL is determined based on the information obtained from at least one item of the first information, the second information, and the third information may be: in response to the HARQ-ACKs received by the DL corresponding to one or more activated DL reception configurations, the HARQ-ACKs are multiplexed in a HARQ-ACK codebook (that is, the HARQ-ACK codebook only contains HARQ-ACKs for SPS PDSCHs), and the HARQ-ACK received by the DL is determined according to the agreed rules.

[0061] Among them, DL reception is SPS configuration.

[0062] Idea 1:

[0063] In one embodiment, according to an agreed rule, a method for determining HARQ-ACK for DL ​​reception includes at least one of the following: if a transmission mode configured for a DL reception configuration is to transmit only in a first type OFDM symbol, and in a slot, the DL reception corresponding symbol corresponding to the DL reception configuration is determined to be a second type OFDM symbol, then HARQ-ACK for DL ​​reception is not generated. If a transmission mode configured for a DL reception configuration is to transmit only in a second type OFDM symbol, and in a slot, the DL reception corresponding symbol corresponding to the DL reception configuration is determined to be a first type OFDM symbol, then HARQ-ACK for DL ​​reception is not generated. If a transmission mode configured for a DL reception configuration is that different DL receptions corresponding to the DL reception configuration are transmitted in first type OFDM symbols and second type OFDM symbols in different slots, and in a slot, the DL reception corresponding symbol corresponding to the DL reception configuration includes first type OFDM symbols and second type OFDM symbols, then HARQ-ACK for DL ​​reception is not generated.

[0064] For example, assuming that the SBFD symbol / slot is configured for the UE, that is, the UE knows the location of the SBFD resource, then according to the agreed rules, the method for determining the HARQ-ACK received by the DL includes at least one of the following:

[0065] If an SPS configuration is determined / configured to be transmitted only in SBFD symbols (based on option 1-1 above), that is, all SPS PDSCHs of the SPS configuration are transmitted only in SBFD symbols in different slots, and the symbols corresponding to the SPS PDSCH of the SPS configuration in a slot are determined to be non-SBFD symbols (that is, the symbols corresponding to the SPS PDSCH in the slot include SBFD symbols and non-SBFD symbols, that is, the symbols corresponding to the SPS PDSCH in the slot are not all SBFD symbols), then the UE does not generate HARQ-ACK for the SPS PDSCH. Otherwise, the UE generates HARQ-ACK for the SPS PDSCH in the slot.

[0066] Alternatively, if an SPS configuration is determined / configured to be transmitted only in non-SBFD symbols (excluding UL symbols) (based on option 1-2 above), that is, all SPS PDSCHs of the SPS configuration are transmitted only in non-SBFD symbols in different slots, and in a slot, the symbols corresponding to the SPS PDSCH of the SPS configuration are determined to be SBFD symbols (that is, the symbols corresponding to the SPS PDSCH in the slot include SBFD symbols and non-SBFD symbols, that is, the symbols corresponding to the SPS PDSCH in the slot are not all non-SBFD symbols), then the UE does not generate HARQ-ACK for the SPS PDSCH. Otherwise, the UE generates HARQ-ACK for the SPS PDSCH in the slot.

[0067] Alternatively, if an SPS configuration is determined / configured based on the above-mentioned Option 2, that is, different SPS PDSCHs of the SPS configuration can be transmitted in SBFD symbols and non-SBFD symbols in different slots, and the symbols corresponding to the SPS PDSCH of the SPS configuration in a slot include SBFD symbols and non-SBFD symbols (that is, the symbols corresponding to the SPS PDSCH in the slot are not all SBFD symbols or not all non-SBFD symbols), then the UE does not generate HARQ-ACK for the SPS PDSCH. Otherwise, the UE generates HARQ-ACK for the SPS PDSCH in the slot.

[0068] If the UE determines that the HARQ-ACKs for the aforementioned SPS PDSCHs are intended to be transmitted in UL slot n, then these HARQ-ACKs are multiplexed in a HARQ-ACK codebook and transmitted in a PUCCH resource in UL slot n. In the following cases, the UE determines the HARQ-ACK for DL ​​reception according to at least one of the following rules.

[0069] Rule 1:

[0070] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception can be: in response to the DL reception corresponding to an activated DL reception configuration being configured to receive the DL reception in slot m, if the symbol type of at least one symbol of the DL reception in slot m is different from the symbol type associated with the DL reception configuration, then the HARQ-ACK of DL reception is not generated.

[0071] Exemplarily, the UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If the symbol type of at least one symbol of the SPS PDSCH in slot m is different from the associated symbol type of the SPS configuration, then no HARQ-ACK is generated for the SPS PDSCH.

[0072] Different symbol types refer to different symbol types for SBFD symbols and non-SBFD symbols. The symbol types of symbols in a slot can be determined based on the SBFD symbol / slot configuration information. If an SPS PDSCH is configured for reception in a slot, the symbols used by the SPS PDSCH in that slot can be determined based on the SPS PDSCH's time domain resource configuration information. Thus, the symbol types corresponding to the symbols of the SPS PDSCH in that slot can be determined.

[0073] FIG4 is an example diagram of determining HARQ-ACK for DL ​​reception in an embodiment of the present application. As shown in FIG4 , the SPS configuration corresponding to an SPS PDSCH is determined / configured to be associated with an SBFD symbol / slot, that is, the SPS PDSCHs corresponding to the SPS configuration are only transmitted in SBFD symbols or DL ​​subbands, that is, the transmission mode of the SPS configuration is based on option 1-1 above, that is, the symbol type corresponding to the SPS PDSCH is an SBFD symbol. In FIG4 , the symbols of the SPS PDSCH are #3-#10. In slot m, symbols #0-#9 are SBFD symbols, and symbols #10-#13 are not configured with SBFD symbols, that is, symbols #0-#9 are SBFD symbols, and symbols #10-#13 are non-SBFD symbols. In slot m, symbol #10 among symbols #3-#10 of the SPS PDSCH is a non-SBFD symbol, and the remaining symbols are SBFD symbols. Since the symbol type of symbol #10 is different from the symbol type associated with the SPS configuration corresponding to the SPS PDSCH, the SPS PDSCH in slot m satisfies: the symbol type of at least one symbol of the SPS PDSCH is different from the symbol type associated with the SPS configuration corresponding to the SPS PDSCH, so no HARQ-ACK is generated for the SPS PDSCH.

[0074] For example, Figure 5 is an example diagram of a HARQ-ACK for determining DL reception in an embodiment of the present application. For example, in Figure 5, the SPS configuration corresponding to an SPS PDSCH is determined / configured to be associated with a CCFD symbol / slot, that is, the SPS PDSCHs corresponding to the SPS configuration are only transmitted in CCFD symbols, that is, the transmission mode of the SPS configuration is based on the above-mentioned option 1A-1, that is, the symbol type corresponding to the SPS PDSCH is a CCFD symbol. In Figure 5, the symbols of the SPS PDSCH are #3-#10. In slot m, symbols #0-#9 are CCFD symbols, and symbols #10-symbol #13 are not configured with CCFD symbols, that is, symbols #0-#9 are CCFD symbols, and symbols #10-symbol #13 are non-CCFD symbols. In the slot m, symbol #10 among the symbols #3-#10 of the SPS PDSCH is a non-CCFD symbol, and the remaining symbols are CCFD symbols. Since the symbol type of symbol #10 is different from the symbol type associated with the SPS configuration corresponding to the SPS PDSCH, the SPS PDSCH in slot m satisfies: the symbol type of at least one symbol of the SPS PDSCH is different from the symbol type associated with the SPS configuration corresponding to the SPS PDSCH, so no HARQ-ACK is generated for the SPS PDSCH.

[0075] Rule 2:

[0076] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception can be: in response to the DL reception corresponding to an activated DL reception configuration being configured to receive the DL reception in slot m, if the symbol type of at least one symbol of the DL reception in slot m is different from the symbol type associated with the DL reception configuration, then generating the HARQ-ACK of DL reception.

[0077] Exemplarily, the UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If the symbol type of at least one symbol of the SPS PDSCH in the slot m is different from the symbol type associated with the SPS configuration, then HARQ-ACK is generated for the SPS PDSCH. Furthermore, the SPS PDSCH is transmitted only in symbols of the same symbol type as the SPS configuration associated with it. Note: The modulation coding of the SPS PDSCH does not change. It is assumed that it is still transmitted in all symbols corresponding to the SPS PDSCH, but the data planned to be transmitted in symbols of different symbol types is not mapped for transmission in these symbols, that is, these symbols are punctured. This method can avoid re-encoding the SPS PDSCH after the SPS PDSCH resources change, and is more suitable for repeated transmission of the SPS PDSCH. Another approach is to determine the resources on which the SPS PDSCH is actually transmitted (i.e., excluding symbols of a different symbol type from that associated with the SPS PDSCH), modulate and encode the SPS PDSCH according to the size of the resources actually transmitted, and then transmit the SPS PDSCH using the resources actually transmitted.

[0078] Rule 3:

[0079] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception can be: in response to the DL reception corresponding to an activated DL reception configuration being configured to receive the DL reception in slot m, if the symbol type of all symbols of the DL reception in slot m is different from the symbol type associated with the DL reception configuration, then the HARQ-ACK of DL reception is not generated.

[0080] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If the symbol types of all symbols of the SPS PDSCH in slot m are different from the symbol types associated with the SPS configuration, no HARQ-ACK is generated for the SPS PDSCH.

[0081] Rule 4:

[0082] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception can be: in response to the DL reception corresponding to an activated DL reception configuration being configured to receive the DL reception in slot m, if the symbol type of all symbols of the DL reception in slot m is different from the symbol type associated with the DL reception configuration, then generating the HARQ-ACK of DL reception.

[0083] Exemplarily, the UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If the symbol type of all symbols of the SPS PDSCH in slot m is different from the symbol type associated with the SPS configuration, then a HARQ-ACK is generated for the SPS PDSCH, for example, a NACK.

[0084] Rule 5:

[0085] In one embodiment, in response to being configured to receive a DL reception corresponding to an activated DL reception configuration in slot m, if the symbol type of all symbols received in slot m is the same as the symbol type associated with the DL reception configuration, a HARQ-ACK for the DL reception is generated.

[0086] Exemplarily, the UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If the symbol type of all symbols of the SPS PDSCH in slot m is the same as the symbol type associated with the SPS configuration, then HARQ-ACK is generated for the SPS PDSCH, for example, based on the decoding result of the SPS PDSCH.

[0087] Rule 6:

[0088] In one embodiment, in response to being configured to receive a DL reception corresponding to an activated DL reception configuration in slot m, if the symbol type of at least two symbols of the DL reception in slot m is the same as the symbol type associated with the DL reception configuration, a HARQ-ACK for the DL reception is generated.

[0089] Exemplarily, the UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If the symbol type of at least two symbols of the SPS PDSCH in slot m is the same as the symbol type associated with the SPS configuration, then HARQ-ACK is generated for the SPS PDSCH, for example, HARQ-ACK is generated based on the decoding result of the SPS PDSCH. Note: The modulation and coding of the SPS PDSCH does not change. It is assumed that it is still transmitted in all symbols corresponding to the SPS PDSCH, but the data planned to be transmitted in symbols of different symbol types is not mapped for transmission in these symbols, that is, these symbols are punctured. This method can avoid re-encoding the SPS PDSCH after the SPS PDSCH resources change, and is more suitable for repeated transmission of the SPS PDSCH. Another approach is to determine the resources on which the SPS PDSCH is actually transmitted (i.e., excluding symbols of a different symbol type from that associated with the SPS PDSCH), modulate and encode the SPS PDSCH according to the size of the resources actually transmitted, and then transmit the SPS PDSCH using the resources actually transmitted.

[0090] Rule 7:

[0091] In one embodiment, in response to being configured to receive a DL reception corresponding to an activated DL reception configuration in slot m, if the symbol type of the DL reception in slot m exceeds a set proportion of symbols and is different from the symbol type associated with the DL reception configuration, then HARQ-ACK for the DL reception is not generated.

[0092] The set ratio may be agreed to be 1 / 2, 1 / 3, or 1 / 4. For example, a UE is configured to receive an SPS PDSCH of an activated SPS configuration in slot m. If, in slot m, the SPS PDSCH has more than a set ratio of symbols whose symbol type is different from the symbol type associated with the SPS configuration, then no HARQ-ACK is generated for the SPS PDSCH; otherwise, a HARQ-ACK is generated for the SPS PDSCH.

[0093] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception can be: in response to the DL reception corresponding to an activated DL reception configuration with repeated transmission, according to the agreed rules, determining the HARQ-ACK of the DL reception with repeated transmission.

[0094] Rule 8:

[0095] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK of DL reception with repeated transmission can be: in response to the DL reception corresponding to the configured reception of an activated DL reception configuration in slot m-R+1 to slot m, only in one or more slots other than slot m-R+1, according to the agreed rules, determine whether to generate HARQ-ACK for DL ​​reception.

[0096] Where R is the number of retransmissions. For example, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slots m-R+1 to slot m. If the SPS PDSCH is only in one or more slots other than slot m-R+1, any of the above rules 1 to 7 is used to determine whether to generate HARQ-ACK for the SPS PDSCH.

[0097] Rule 9:

[0098] In one embodiment, in response to being configured to receive an activated DL reception configuration corresponding to the DL reception in slot m-R+1 to slot m, always in slot m-R+1, it is determined whether to generate HARQ-ACK for the DL reception according to the agreed rules.

[0099] For example, a UE is configured to receive an SPS PDSCH with an activated SPS configuration in slots m-R+1 to slot m, and always uses any Alt in the above rules 1 to 7 in the first slot (i.e., slot m-R+1) to determine whether to generate a HARQ-ACK for the SPS PDSCH. If it is determined that a HARQ-ACK is to be generated for the SPS PDSCH, a HARQ-ACK is generated for the SPS PDSCH, regardless of the determination results in subsequent slots.

[0100] Rule 10:

[0101] In one embodiment, in response to the DL reception corresponding to the configured reception of an activated DL reception configuration in slot m-R+1 to slot m, the HARQ-ACK for DL ​​reception is determined one by one in R slots according to the agreed rules; if it is determined to generate the HARQ-ACK for DL ​​reception in one slot, the HARQ-ACK for DL ​​reception is generated; if it is determined not to generate the HARQ-ACK for DL ​​reception in each slot, the HARQ-ACK for DL ​​reception is not generated.

[0102] For example, a UE is configured to receive an SPS PDSCH configured with an activated SPS in slot m-R+1 to slot m, and determines whether to generate a HARQ-ACK for the SPS PDSCH using any one of the above rules 1 to 7 for each of the R slots. If a HARQ-ACK is determined to be generated for the SPS PDSCH in a slot, a HARQ-ACK is generated for the SPS PDSCH. If a HARQ-ACK is determined not to be generated for the SPS PDSCH in each slot, a HARQ-ACK is not generated for the SPS PDSCH.

[0103] Rule 11:

[0104] In one embodiment, in response to the DL reception corresponding to the configured reception of an activated DL reception configuration in slot m-R+1 to slot m, the HARQ-ACK for DL ​​reception is determined one by one in R slots according to the agreed rules; if it is determined not to generate the HARQ-ACK for DL ​​reception in one slot, the HARQ-ACK for DL ​​reception is not generated; if it is determined to generate the HARQ-ACK for DL ​​reception in each slot, the HARQ-ACK for DL ​​reception is generated.

[0105] For example, a UE is configured to receive an SPS PDSCH configured with an activated SPS in slot m-R+1 to slot m, and determines whether to generate a HARQ-ACK for the SPS PDSCH using any one of the above rules 1 to 7 in each of the R slots. If a determination is made in a slot that a HARQ-ACK is not to be generated for the SPS PDSCH, then a HARQ-ACK is not generated for the SPS PDSCH. If a determination is made in each slot that a HARQ-ACK is to be generated for the SPS PDSCH, then a HARQ-ACK is generated for the SPS PDSCH.

[0106] In an embodiment of the present application, SBFD in rules 1 to 11 can be replaced with CCFD, or the symbol types in rules 1 to 11 can be divided into CCFD symbols and non-CCFD symbols, so that rules 1 to 11 are applicable to CCFD-based SPS PDSCH transmission.

[0107] Idea 2:

[0108] In one embodiment, according to the agreed rules, the method for determining the HARQ-ACK for DL ​​reception can be: if the DL reception resources corresponding to a DL reception configuration in a slot overlap with the resources of the UL subband in the first type of OFDM symbol, the HARQ-ACK for DL ​​reception in the slot is not generated; if the DL reception resources corresponding to a DL reception configuration in a slot are in the resources of the UL subband in the first type of OFDM symbol, the HARQ-ACK for DL ​​reception in the slot is not generated; if the DL reception resources corresponding to a DL reception configuration in a slot partially overlap with the resources of the UL subband of the first type of OFDM symbol, the HARQ-ACK for DL ​​reception in the slot is not generated.

[0109] Alternatively, according to the agreed rules, the method for determining the HARQ-ACK for DL ​​reception may be: if the DL reception resources corresponding to a DL reception configuration in a slot overlap with the resources of the UL subband in the first type of OFDM symbol, then the HARQ-ACK for DL ​​reception in the slot is generated; if the DL reception resources corresponding to a DL reception configuration in a slot are in the resources of the UL subband in the first type of OFDM symbol, then the HARQ-ACK for DL ​​reception in the slot is generated; if the DL reception resources corresponding to a DL reception configuration in a slot partially overlap with the resources of the UL subband of the first type of OFDM symbol, then the HARQ-ACK for DL ​​reception in the slot is generated.

[0110] If the UE determines that the HARQ-ACKs for the aforementioned SPS PDSCHs are intended to be transmitted in UL slot n, then these HARQ-ACKs are multiplexed in a HARQ-ACK codebook and transmitted in a PUCCH resource in UL slot n. Approach 2 has the following situation: the UE determines the HARQ-ACK for DL ​​reception according to at least one of the following rules.

[0111] Rule 12:

[0112] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if resources of the DL reception in slot m overlap with resources of a UL subband of a first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0113] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If resources of the SPS PDSCH in slot m overlap with resources of a UL subband of an SBFD symbol, no HARQ-ACK is generated for the SPS PDSCH.

[0114] For example, an SPS configuration is configured to be associated with an SBFD symbol. Figure 6 is an example diagram of determining the HARQ-ACK received by DL in an embodiment of the present application. In Figure 6, the symbols of the SPS PDSCH of the SPS configuration are all SBFD symbols, that is, in the slot of Figure 6, the symbol type of the SPS PDSCH is the same as the associated symbol type, but because the resources of the SPS PDSCH overlap with the resources of the UL subband of the SBFD symbol, the SPS PDSCH does not generate HARQ-ACK. Although it is determined that the SPS PDSCH should generate HARQ-ACK according to the conditions in Rules 1 to 7, it is determined that the SPS PDSCH should not generate HARQ-ACK according to the conditions in Rule 12, then combining the two determination results, as long as one does not generate HARQ-ACK, then the SPS PDSCH will not generate HARQ-ACK in the end.

[0115] For example, an SPS configuration is configured to be associated with CCFD symbols. Figure 7 is an example diagram of determining the HARQ-ACK received by DL in an embodiment of the present application. In Figure 7, the symbols of the SPS PDSCH of the SPS configuration are all CCFD symbols, that is, in the slot of Figure 7, the symbol type of the SPS PDSCH is the same as the associated symbol type, but because the resources of the SPS PDSCH overlap with the resources of resource A of the CCFD symbol, the SPS PDSCH does not generate HARQ-ACK. Although it is determined that the SPS PDSCH should generate HARQ-ACK according to the conditions in Rules 1 to 7, it is determined that the SPS PDSCH should not generate HARQ-ACK according to the conditions in Rule 12, then combining the two determination results, as long as one does not generate HARQ-ACK, the SPS PDSCH will ultimately not generate HARQ-ACK.

[0116] Rule 13:

[0117] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if the resources of the DL reception in slot m are in the resources of the UL subband of the first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0118] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If the resources of the SPS PDSCH in slot m are in the resources of the UL subband of the SBFD symbol, that is, the resources of the SPS PDSCH completely fall within the resources of the UL subband, then no HARQ-ACK is generated for the SPS PDSCH.

[0119] Rule 14:

[0120] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if resources of the DL reception in slot m partially overlap with resources of a UL subband of a first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0121] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If part of the resources of the SPS PDSCH in slot m are in the resources of the UL subband of the SBFD symbol, that is, part of the resources of the SPS PDSCH are in the resources of the UL subband, then HARQ-ACK is not generated for the SPS PDSCH.

[0122] Rule 15:

[0123] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if resources of the DL reception in slot m overlap with resources of a UL subband of a first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0124] For example, a UE is configured to receive an SPS PDSCH configured with an activated SPS in slot m. If the resources of the SPS PDSCH in slot m overlap with the resources of the UL subband of the SBFD symbol, a HARQ-ACK is generated for the SPS PDSCH. Note: The modulation and coding of the SPS PDSCH does not change. It is assumed that it is still transmitted in all symbols corresponding to the SPS PDSCH, but the data planned to be transmitted in symbols of different symbol types is not mapped for transmission in these symbols, that is, these symbols are punctured. This approach avoids re-encoding the SPS PDSCH after the SPS PDSCH resources change and is more suitable for situations where the SPS PDSCH is repeatedly transmitted. Another approach is to determine the resources actually transmitted by the SPS PDSCH (i.e., excluding symbols of a different symbol type associated with the SPS PDSCH), perform modulation and coding on the SPS PDSCH based on the size of the resources actually transmitted, and then use the resources actually transmitted to transmit the SPS PDSCH.

[0125] Rule 16:

[0126] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if the resources of the DL reception in slot m are in the resources of the UL subband of the first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0127] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If the resources of the SPS PDSCH in slot m are in the resources of the UL subband of the SBFD symbol, that is, the resources of the SPS PDSCH completely fall within the resources of the UL subband, then HARQ-ACK is generated for the SPS PDSCH, for example, always NACK.

[0128] Rule 17:

[0129] In one embodiment, in response to being configured to receive an activated DL reception configured for DL ​​reception in slot m, if resources of the DL reception in slot m partially overlap with resources of a UL subband of a first type of OFDM symbol, HARQ-ACK for the DL reception is not generated.

[0130] Exemplarily, the UE is configured to receive an SPS PDSCH with an activated SPS configuration in slot m. If part of the resources of the SPS PDSCH in slot m are in the resources of the UL subband of the SBFD symbol, that is, part of the resources of the SPS PDSCH are in the resources of the UL subband, then HARQ-ACK is generated for the SPS PDSCH. Note: The modulation and coding of the SPS PDSCH does not change. It is assumed that it is still transmitted in all symbols corresponding to the SPS PDSCH, but the data planned to be transmitted in symbols of different symbol types is not mapped for transmission in these symbols, that is, these symbols are punctured. This method can avoid re-encoding the SPS PDSCH after the SPS PDSCH resources change, and is more suitable for repeated transmission of the SPS PDSCH. Another approach is to determine the resources on which the SPS PDSCH is actually transmitted (i.e., excluding symbols of a different symbol type from that associated with the SPS PDSCH), modulate and encode the SPS PDSCH according to the size of the resources actually transmitted, and then transmit the SPS PDSCH using the resources actually transmitted.

[0131] In one embodiment, the method for determining HARQ-ACK of DL reception can be: in response to DL reception with repeated transmission corresponding to an activated DL reception configuration, determining HARQ-ACK of DL reception with repeated transmission according to an agreed rule.

[0132] Rule 18:

[0133] In one embodiment, in response to being configured to receive an activated DL reception configuration corresponding to the DL reception in slot m-R+1 to slot m, only in one or more slots other than slot m-R+1, according to the agreed rules, it is determined whether to generate the HARQ-ACK of the DL reception.

[0134] Where R is the number of retransmissions. For example, if a UE is configured to receive an SPS PDSCH with an activated SPS configuration in slots m-R+1 to slot m, and if the SPS PDSCH is only in one or more slots other than slot m-R+1, any one of the above rules 12 to 17 is used to determine whether to generate HARQ-ACK for the SPS PDSCH.

[0135] Rule 19:

[0136] In one embodiment, in response to being configured to receive an activated DL reception configuration corresponding to the DL reception in slot m-R+1 to slot m, always in slot m-R+1, it is determined whether to generate HARQ-ACK for the DL reception according to the agreed rules.

[0137] For example, a UE is configured to receive an SPS PDSCH with an activated SPS configuration in slots m-R+1 to slot m, and always uses any one of the above rules 12 to 17 in the first slot (i.e., slot m-R+1) to determine whether to generate a HARQ-ACK for the SPS PDSCH. If it is determined that a HARQ-ACK is to be generated for the SPS PDSCH, a HARQ-ACK is generated for the SPS PDSCH, regardless of the determination results in subsequent slots.

[0138] Rule 20:

[0139] In one embodiment, in response to the DL reception corresponding to the configured reception of an activated DL reception configuration in slot m-R+1 to slot m, the HARQ-ACK of the DL reception is determined one by one in R slots according to the agreed rules; if it is determined to generate the HARQ-ACK of the DL reception in one slot, the HARQ-ACK of the DL reception is generated; if it is determined not to generate the HARQ-ACK of the DL reception in each slot, the HARQ-ACK of the DL reception is not generated.

[0140] For example, a UE is configured to receive an SPS PDSCH configured with an activated SPS in slot m-R+1 to slot m, and determines whether to generate a HARQ-ACK for the SPS PDSCH using any one of the above rules 12 to 17 in each of the R slots. If a HARQ-ACK is determined to be generated for the SPS PDSCH in a slot, a HARQ-ACK is generated for the SPS PDSCH. If a HARQ-ACK is determined not to be generated for the SPS PDSCH in each slot, a HARQ-ACK is not generated for the SPS PDSCH.

[0141] Rule 21:

[0142] In one embodiment, in response to the DL reception corresponding to the configured reception of an activated DL reception configuration in slot m-R+1 to slot m, the HARQ-ACK of the DL reception is determined one by one in R slots according to the agreed rules; if it is determined not to generate the HARQ-ACK of the DL reception in one slot, the HARQ-ACK of the DL reception is not generated; if it is determined to generate the HARQ-ACK of the DL reception in each slot, the HARQ-ACK of the DL reception is generated.

[0143] For example, a UE is configured to receive an SPS PDSCH configured with an activated SPS in slot m-R+1 to slot m, and determines whether to generate a HARQ-ACK for the SPS PDSCH using any one of the above rules 12 to 17 in each of the R slots. If a determination is made in a slot that a HARQ-ACK is not to be generated for the SPS PDSCH, then a HARQ-ACK is not generated for the SPS PDSCH. If a determination is made in each slot that a HARQ-ACK is to be generated for the SPS PDSCH, then a HARQ-ACK is generated for the SPS PDSCH.

[0144] In an embodiment of the present application, SBFD in rules 12-21 can be replaced with CCFD, or the symbol types in rules 12-21 can be divided into CCFD symbols and non-CCFD symbols, so that rules 12-21 are applicable to CCFD-based SPS PDSCH transmission.

[0145] In the embodiment of the present application, rules 1 to 11 based on idea 1 mainly use the symbol type of the SPS PDSCH symbol to determine whether to generate HARQ-ACK for the SPS PDSCH. Rules 12 to 21 based on idea 2 mainly use the frequency domain resources of the SPS PDSCH to determine whether to generate HARQ-ACK for the SPS PDSCH. Ideas 1 and 2 can be used in combination when they do not conflict. For example, for the examples of Figures 8 and 9, the rules based on idea 1 and the skeleton amount based on idea 2 can be used in combination.

[0146] In the case of SBFD or CCFD, the two ideas are combined and if the results of generating HARQ-ACK are the same, the result is used as the SPS PDSCH.

[0147] In the case of SBFD or CCFD, if the two types of Alts are used in combination and the HARQ-ACK generation results are different, the result of Approach 2 is used as the final result.

[0148] Alternatively, when the two approaches are combined in the case of SBFD or CCFD, if the results of generating HARQ-ACK are different, the result of approach 1 or approach 2 is used as the final result according to the pre-agreed agreement (between the base station and the UE).

[0149] In one embodiment, the method further includes: in response to a DL reception configuration being configured to perform DL reception based on a transmission mode, if a DL reception corresponding to the DL reception configuration is not transmitted in a certain slot because the symbol type of the DL reception symbol is different from the symbol type associated with the DL reception configuration, then according to the agreed rules, determining the usage method of the DL reception resources corresponding to the DL reception in the slot.

[0150] In one embodiment, according to the agreed rules, the method for determining the usage of the DL reception resources corresponding to the DL reception in the slot can be: if a DL reception corresponding to the DL reception configuration is not transmitted in a certain slot because the symbol type of the DL reception symbol is different from the symbol type associated with the DL reception configuration, then the resources corresponding to the DL reception can be used for data transmission based on DCI scheduling, or, the resources corresponding to the DL reception are not used for data transmission based on DCI scheduling.

[0151] In an embodiment of the present application, if an SPS configuration is configured or associated based on the above-mentioned option 1-1 or option 1-2, including in the case of CCFD operation, if an SPS configuration is configured or associated based on the above-mentioned option 1A-1 or option 1A-2, and if an SPS PDSCH of the SPS configuration is not transmitted in a certain slot because the symbol type of the symbol of the SPS PDSCH is different from the symbol type of the SPS configuration configured or associated, then in the slot, how the PDSCH resources corresponding to the SPS PDSCH should be processed is a problem that needs to be solved.

[0152] To fully utilize PDSCH resources, the base station and UE agree that the PDSCH resources can be used for transmission of downlink data scheduled by DCI in the above situation. That is, if a PDSCH resource associated with an SPS configuration is not used for data transmission in a slot because the symbol type configured or associated with the SPS configuration is different from the symbol type corresponding to the PDSCH resource in the slot, then the PDSCH resource can be used for data transmission based on DCI scheduling (or the PDSCH resource cannot be used for transmission of data scheduled by DCI).

[0153] In this case, the PDSCH resource is used to generate HARQ-ACK for DCI-scheduled data transmission.

[0154] For example, in Figure 10, an SPS configuration is configured or associated based on Option 1-1, meaning that the SPS PDSCH of this SPS configuration is transmitted in a slot using only SBFD symbols. In Figure 10, an SPS PDSCH symbol of this SPS configuration is a non-SBFD symbol. Based on the above assumption, the symbol type associated with this SPS PDSCH differs from the symbol type of the SPS PDSCH symbol in this slot. Therefore, this SPS PDSCH cannot be transmitted in this slot, meaning that this SPS PDSCH cannot be used for data transmission in this SPS configuration. Consequently, the PDSCH resource corresponding to this SPS PDSCH becomes idle. To fully utilize PDSCH resources, according to the above method, the base station can schedule a single data transmission in this PDSCH resource based on a DCI, and the UE can receive the data in this PDSCH resource after receiving the DCI. Therefore, this PDSCH resource should also be used to generate HARQ-ACK for the PDSCH scheduled by this DCI.

[0155] The above method can also be extended to CCFD operation. For example, in Figure 11, an SPS configuration is configured or associated based on Option 1A-1, meaning that the SPS PDSCH of this SPS configuration is transmitted in a slot using CCFD symbols only. In Figure 11, an SPS PDSCH symbol of this SPS configuration is a non-CCFD symbol. Based on the above assumption, the symbol type associated with this SPS PDSCH differs from the symbol type of the SPS PDSCH symbol in this slot. Therefore, this SPS PDSCH cannot be transmitted in this slot, meaning that this SPS PDSCH cannot be used for data transmission in this SPS configuration. Consequently, the PDSCH resource corresponding to this SPS PDSCH becomes idle. To fully utilize PDSCH resources, according to the above method, the base station can schedule a single data transmission in this PDSCH resource based on a DCI, and the UE can receive the data in this PDSCH resource after receiving the DCI. Therefore, this PDSCH resource should also be used to generate HARQ-ACK for the PDSCH scheduled by this DCI.

[0156] In one embodiment, the method further comprises:

[0157] In response to configuring independent DL reception resource sets for the first type OFDM symbols or the second type OFDM symbols, respectively, a transmission mode in which the DL reception configuration is configured is determined.

[0158] In one embodiment, in response to configuring independent DL reception resource sets for the first type of OFDM symbol or the second type of OFDM symbol, the method for determining the transmission mode configured by the DL reception configuration may be: if the DL reception resources corresponding to a DL reception configuration are configured from the DL reception resource set corresponding to the first type of OFDM symbol, then the transmission mode configured by the DL reception configuration is to transmit only in the first type of OFDM symbol; if the DL reception resources corresponding to a DL reception configuration are configured from the DL reception resource set corresponding to the second type of OFDM symbol, then the transmission mode configured by the DL reception configuration is to transmit only in the second type of OFDM symbol; if the DL reception resources corresponding to a DL reception configuration are configured as two, and come from the DL reception resource set corresponding to the first type of OFDM symbol and the DL reception resource set corresponding to the second type of OFDM symbol respectively, then the transmission mode configured by the DL reception configuration is that different DL receptions of the DL reception configuration are transmitted in different slots in the first type of OFDM symbol and the second type of OFDM symbol.

[0159] Exemplarily, it is assumed that independent PDSCH resource sets are configured for SBFD symbols or non-SBFD symbols respectively.

[0160] If the PDSCH resources corresponding to an SPS configuration are configured from the PDSCH resource set corresponding to SBFD symbols, then the SPS configuration is defaulted to the above option 1-1. In this way, all SPS PDSCHs of the SPS configuration are transmitted in different slots only in the SBFD symbols in each slot. For example, an SPS PDSCH in slot n of the SPS configuration is transmitted only in SBFD symbols, and another SPS PDSCH in slot m is transmitted only in SBFD symbols.

[0161] If the PDSCH resources corresponding to an SPS configuration are configured from the PDSCH resource set corresponding to non-SBFD symbols, then the SPS configuration is defaulted to option 1-2 above. In this way, all SPS PDSCHs of the SPS configuration are transmitted in different slots only in non-SBFD symbols in each slot. For example, an SPS PDSCH in slot n of the SPS configuration is transmitted only in non-SBFD symbols, and another SPS PDSCH in slot m is transmitted only in non-SBFD symbols.

[0162] If an SPS configuration is configured with two PDSCH resources, and they come from the PDSCH resource set corresponding to non-SBFD symbols and the PDSCH resource set corresponding to SBFD symbols, then the SPS configuration is defaulted to the above-mentioned option 2. In this way, different SPS PDSCHs of the SPS configuration are transmitted in different slots and can be transmitted in both SBFD symbols and non-SBFD symbols. For example, one SPS PDSCH of the SPS configuration is transmitted in slot n only in SBFD symbols, and the other SPS PDSCH is transmitted in slot m only in non-SBFD symbols.

[0163] In one embodiment, in response to the transmission mode configured for the DL reception configuration being transmitted only in first type OFDM symbols, if a DL reception corresponding to the DL reception configuration is in a slot, and the DL reception resource corresponding to the DL reception is a second type OFDM symbol in the slot, then the DL reception is not transmitted in the slot, and the DL reception resource corresponding to the DL reception is not used for data transmission based on DCI scheduling; in response to the transmission mode configured for the DL reception configuration being transmitted only in second type OFDM symbols, if a DL reception corresponding to the DL reception configuration is in a slot, and the DL reception resource corresponding to the DL reception is a first type OFDM symbol in the slot, then the DL reception is not transmitted in the slot, and the DL reception resource corresponding to the DL reception is not used for data transmission based on DCI scheduling.

[0164] Exemplarily, it is assumed that independent PDSCH resource sets are configured for SBFD symbols or non-SBFD symbols respectively.

[0165] If an SPS configuration determines that the PDSCH resource is transmitted only in SBFD symbols, but if an SPS PDSCH corresponding to the SPS configuration has a transmission opportunity in a slot, and the PDSCH resource corresponding to the SPS PDSCH in the slot is a non-SBFD symbol, then the SPS PDSCH is not transmitted in the slot, and the PDSCH resource corresponding to the SPS PDSCH cannot be used for data transmission based on DCI scheduling.

[0166] If an SPS configuration determines that the PDSCH resource is transmitted only in non-SBFD symbols, but if an SPS PDSCH corresponding to the SPS configuration has a transmission opportunity in a slot, and the PDSCH resource corresponding to the SPS PDSCH in the slot is an SBFD symbol, then the SPS PDSCH is not transmitted in the slot, and the PDSCH resource corresponding to the SPS PDSCH cannot be used for data transmission based on DCI scheduling.

[0167] In one embodiment, the method further includes: in response to a type 1 HARQ-ACK codebook containing at least one HARQ-ACK received by a DCI-scheduled DL, determining to generate the type 1 HARQ-ACK codebook according to an agreed rule.

[0168] In one embodiment, if the first type of resource is configured, the method for determining the generation of the type1 HARQ-ACK codebook may be: determining a slot set corresponding to the type1 HARQ-ACK codebook; for each first type slot in the slot set, generating HARQ-ACK based on the candidate DL receive resource, and concatenating the HARQ-ACK generated in each first type slot to obtain a first subcodebook; for each second type slot in the slot set, generating HARQ-ACK based on the candidate DL receive resource, and concatenating the HARQ-ACK generated in each second type slot to obtain a second subcodebook; concatenating the first subcodebook and the second subcodebook to obtain a type1 HARQ-ACK codebook.

[0169] For example, if the UE is configured with SBFD resources and a type 1 HARQ-ACK codebook, the UE constructs a type 1 HARQ-ACK codebook containing the HARQ-ACK of the PDSCH scheduled by the DCI by determining one or more slots based on slot n-k1 based on the slot n in which the type 1 HARQ-ACK codebook is transmitted; k1 is a set containing k1 values, and the k1 value describes the interval between the slot where a PDSCH is located and the slot where the HARQ-ACK corresponding to the PDSCH is located. The k1 set is associated with both SBFD symbols and non-SBFD symbols. Slot n-k1 will obtain one or more slots, depending on the number of k1 values. The determined slots are based on the SBFD subband configuration for SBFD slots and non-SBFD slots. For each SBFD slot, HARQ-ACK is generated based on the candidate PDSCH resource, and the HARQ-ACK generated in each SBFD slot is concatenated to obtain the first subcodebook. For each non-SBFD slot, HARQ-ACK is generated based on the candidate PDSCH resource, and the HARQ-ACK generated in each SBFD slot is concatenated to obtain the second subcodebook. The first subcodebook and the second subcodebook are concatenated to obtain the final type 1 HARQ-ACK codebook.

[0170] In one embodiment, if a same DL reception resource set is configured for a first type OFDM symbol and a second type OFDM symbol, then for a first type slot and a second type slot, the candidate DL reception resource refers to a DL reception resource in the DL reception resource set.

[0171] For example, if the same PDSCH resource set is configured for both SBFD symbols and non-SBFD symbols, the candidate PDSCH resources in the SBFD slots and non-SBFD slots are the PDSCH resources in the PDSCH resource set. That is, the PDSCH resource set is used to generate the first subcodebook and the second subcodebook in the SBFD slots and non-SBFD slots, respectively.

[0172] In one embodiment, if different PDSCH resource sets are configured for first type OFDM symbols and second type OFDM symbols respectively, then for each first type slot, the candidate DL reception resource refers to the DL reception resource in the DL reception resource set corresponding to the first type OFDM symbol; for each second type slot, the candidate DL reception resource refers to the DL reception resource in the DL reception resource set corresponding to the second type OFDM symbol.

[0173] For example, if different PDSCH resource sets are configured for SBFD symbols and non-SBFD symbols, respectively, then the candidate PDSCH resources in the SBFD slots and non-SBFD slots are the PDSCH resource sets associated with the SBFD symbols and the PDSCH resource sets associated with the non-SBFD symbols, respectively. That is, for SBFD slots, the PDSCH resource sets associated with the SBFD symbols are used to generate the first subcodebook. For non-SBFD slots, the PDSCH resource sets associated with the non-SBFD symbols are used to generate the second subcodebook.

[0174] In one embodiment, the slot set includes a first slot subset and a second slot subset, wherein the first slot subset is associated with a first type of OFDM symbol, and the second slot subset is associated with a second type of OFDM symbol; for the first slot subset, a first subcodebook is generated based on slots configured with the first type of OFDM symbol; and for the second slot subset, a second subcodebook is generated based on slots configured with the second type of OFDM symbol.

[0175] For example, if one k1 set is configured / associated with SBFD symbols and another k1 set is configured / associated with non-SBFD symbols, the k1 set configured / associated with SBFD symbols may actually include slots that are not configured with SBFD symbols. Slots configured with SBFD symbols in the k1 set configured / associated with SBFD symbols are used to generate the first sub-codebook. Slots not configured with SBFD symbols in the k1 set configured / associated with SBFD symbols are not used to generate the first sub-codebook. The k1 set configured / associated with non-SBFD symbols may actually include slots configured with SBFD symbols. Slots not configured with SBFD symbols in the k1 set configured / associated with non-SBFD symbols are used to generate the second sub-codebook. Slots configured with SBFD symbols in the k1 set configured / associated with SBFD symbols are not used to generate the second sub-codebook.

[0176] In one embodiment, the first type of resource is configured, and the type2 HARQ-ACK codebook is determined as follows: the counted downlink assignment index (DAI) value in the DCIs corresponding to the DL reception transmitted in the first type of OFDM symbol and the counted DAI value in the DCIs corresponding to the DL reception transmitted in the second type of OFDM symbol are allowed to be continuous, and the type2 HARQ-ACK codebook is generated based on the order of the DAI values.

[0177] For example, if a UE is configured with SBFD subbands and a type-2 HARQ-ACK codebook, the UE generates a type-2 HARQ-ACK codebook based on the following sequence: the counter downlink assignment indicator (counter DAI) values ​​in the DCIs corresponding to the PDCCHs of the PDSCHs transmitted in the SBFD symbols and the PDSCHs transmitted in the non-SBFD symbols can be counted consecutively, and a type-2 HARQ-ACK codebook is constructed based on the numerical order of the DAI. For example, if PDSCH1 is transmitted in the first DCI scheduled in the SBFD symbol and PDSCH2 is transmitted in the second DCI or DC2 scheduled in the non-SBFD symbol, the DAI value in the first DCI and the DAI value in the second DCI can be counted consecutively. In this way, the HARQ-ACK for PDSCH1 in the SBFD symbol and the HARQ-ACK for PDSCH2 in the non-SBFD symbol are consecutively counted in the type-2 HARQ-ACK codebook based on the DAI value in the first DCI and the DAI value in the second DCI.

[0178] In this embodiment, the total DAI value in the DCI in the PDCCH corresponding to the PDSCH transmitted in the SBFD symbol can include the PDSCH received in non-SBFD symbols and the PDSCH received in SBFD symbols. The total DAI value in the DCI in the PDCCH corresponding to the PDSCH transmitted in the non-SBFD symbol can also include the PDSCH received in non-SBFD symbols and the PDSCH received in SBFD symbols.

[0179] In one embodiment, if the first type of resources are configured, the type 2 HARQ-ACK codebook is determined as follows: only the counted DAI values ​​in the DCIs corresponding to the DL reception transmitted in the first type of OFDM symbols are allowed to be continuous, and the third sub-codebook is generated based on the order of the DAI values;

[0180] If the count DAI values ​​in the DCIs corresponding to DL reception transmitted only in the second type OFDM symbol are allowed to be continuous, a fourth subcodebook is generated based on the order of the DAI values; and the third subcodebook and the fourth subcodebook are concatenated to obtain the type 2 HARQ-ACK codebook.

[0181] In one embodiment, the HARQ-ACK for SPS DL reception in response to the SPS configuration is multiplexed with the type 2 HARQ-ACK codebook, and the HARQ-ACK for SPS DL reception is concatenated at the end of the type 2 HARQ-ACK codebook to obtain the final type 2 HARQ-ACK codebook. The DL reception only includes DL receptions that are determined to require HARQ-ACK generation.

[0182] For example, if the HARQ-ACK of the SPS PDSCH configured with SPS is to be multiplexed with the type2 HARQ-ACK codebook, then: for the SPS PDSCH configured with SPS, determine whether to generate HARQ-ACK based on the above-mentioned rules 1-rule 21. If HARQ-ACK is generated for the SPS PDSCH configured with SPS, then the HARQ-ACK is concatenated at the end of the above-mentioned type2 HARQ-ACK codebook to obtain the final type2 HARQ-ACK codebook.

[0183] The technical solution of the embodiment of the present application receives at least one of first information, second information, and third information; and determines, according to an agreed rule, a HARQ-ACK for downlink (DL) reception based on information obtained from at least one of the first information, the second information, and the third information.
