[0013] 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.

[0014] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0015] 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.

[0016] To improve uplink (UL) coverage, UL latency, and UL capacity in time division duplexing (TDD) systems, subband full duplex (SBFD) technology has been proposed. SBFD subbands can be configured in downlink (DL) symbols / DL slots and F symbols / F slots. SBFD subbands typically include UL subbands and DL subbands. Generally, UL subbands are used for UL transmission, and DL subbands are used for DL ​​transmission. DL subbands and UL subbands are configured based on resource blocks (RBs). Symbols configured with SBFD subbands are called SBFD symbols, and slots containing SBFD symbols are called SBFD slots. Symbols not configured with SBFD subbands are called non-SBFD symbols (i.e., regular DL symbols), and slots not containing SBFD symbols are called non-SBFD slots.

[0017] 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:

[0018] 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.

[0019] 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).

[0020] Furthermore, the above option 1 can be divided into two options:

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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:

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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).

[0030] Furthermore, option 1A can be divided into two options:

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] In the prior art, a transmission configuration needs to be configured with multiple parameters to support the execution of the transmission corresponding to the transmission configuration. For example, if a transmission configuration is an SPS configuration, then in order for the SPS configuration to be executed, the following parameters are required: frequency domain resource assignment (FDRA), time domain resource assignment (TDRA), modulation and coding scheme (MCS), transmission power control command (TPC command for scheduled PUCCH, TPC), PDSCH to HARQ-ACK timing interval (PDSCH-to-HARQ_feedback timing indicator), VRB to PRB mapping method (VRB-to-PRB mapping). In the prior art, the above parameters are included in the DCI used to activate the SPS configuration. Furthermore, the activation DCI also includes Downlink assignment index (DAI) and PUCCH resource indicator (PRI). However, in the prior art, for an SPS configuration, there is only one set of the above parameters.

[0038] However, in actual transmission configurations, different transmissions corresponding to a transmission configuration can be executed in different slots by using SBFD symbols and non-SBFD symbols. For example, assuming that a transmission configuration is an SPS configuration, and the period of the SPS configuration is 2 slots, and the SPS configuration is determined to support the above-mentioned option 2, then at the first transmission opportunity of the SPS configuration, an SPS PDSCH of the SPS configuration is executed in the SBFD symbol, and at the second transmission opportunity, another SPS PDSCH of the SPS configuration is executed in the non-SBFD symbol. Obviously, the two transmissions of the SPS configuration are in symbols corresponding to different symbol types. Based on the above analysis, the channel environment in the SBFD symbol is quite different from the channel environment in the non-SBFD symbol (the interference difference is very large). Therefore, this application recommends that for the transmission of the SPS configuration in the two symbol types, the corresponding parameters should be considered separately. For example, each of the above-mentioned multiple parameters requires two corresponding parameter values, one parameter is used for transmission in the SBFD symbol, and the other parameter is used for transmission in the non-SBFD symbol. For example, with respect to the MCS parameter, two MCS parameters are required, one MCS parameter is used for transmission of the SPS PDSCH in the SBFD symbol, and the other MCS parameter is used for transmission of the SPS PDSCH in the non-SBFD symbol.

[0039] Furthermore, in order to achieve that each of the above multiple parameters has 2, the following method is proposed. The following method can be used to determine corresponding parameters for different transmissions of the transmission configuration when different transmissions of the transmission configuration are transmitted in different types of symbols. For example, if a transmission configuration is determined to perform transmission based on the above option 2, then based on the following method, the transmission configuration can obtain parameters associated with different types of symbols (for example, parameters used when transmitting in SBFD symbols and parameters used when transmitting in non-SBFD symbols). Ultimately, different transmissions of the transmission configuration use parameters corresponding to the symbol type in SBFD symbols and non-SBFD symbols to perform corresponding transmissions.

[0040] The above situation applies to both CCFD and non-CCFD symbols. For example, if a transmission configuration is determined to perform transmission based on Option 2A, then similarly, based on the following method, the transmission configuration can obtain transmission parameters associated with different symbol types (e.g., parameters used when transmitting in CCFD symbols and parameters used when transmitting in non-CCFD symbols). Ultimately, the different transmissions of the transmission configuration perform corresponding transmissions in CCFD and non-CCFD symbols using parameters corresponding to the symbol type.

[0041] In the related art, DCI formats used for downlink unicast transmission include multiple DCI formats. Different DCI formats have different size requirements. Among them, the size of DCI format 1-0 is small and fixed. The size of each parameter in DCI 1-0 is also fixed, and the presence or size of each parameter cannot be configured by Radio Resource Control (RRC) signaling. DCI 1-0 can be used in situations where RRC signaling is ambiguous or the channel quality is poor. Therefore, if a new parameter is added to DCI 1-0, this practice is unacceptable because it will cause the size of DCI 1-0 to change. For DCI format 1-1 or DCI format 1-2, their size is larger and can be changed. For example, the size of the parameters they contain can be configured by RRC signaling. The presence or absence of each parameter in DCI 1-1 and DCI 1-2 can also be configured by RRC signaling. The DCI format used for downlink unicast transmission can be used to activate an SPS configuration for unicast.

[0042] In the related art, DCI formats used for uplink unicast transmission include multiple DCI formats. Different DCI formats have different size requirements. Among them, the size of DCI format 0-0 is small and fixed. The size of each parameter in DCI 0-0 is also fixed, and the presence and size of each parameter cannot be configured by RRC signaling. DCI 0-0 can be used in situations where RRC signaling is ambiguous or the channel quality is poor. Therefore, if a new parameter is added to DCI 0-0, this practice is unacceptable because it will cause the size of DCI 0-0 to change. For example, the size of the parameters they contain can be configured by RRC signaling. The presence or absence of each parameter in DCI 0-1 and DCI 0-2 can also be configured by RRC signaling. The DCI format used for uplink unicast transmission can be used to activate a CG PUSCH configuration for unicast.

[0043] In the related art, for the DCI format of multicast, DCI includes multiple DCI formats. Different DCI formats have different requirements for size. Among them, the size of DCI format 4-1 is small and fixed. The size of each parameter in DCI 4-1 is also fixed, and the presence or absence and size of each parameter cannot be configured by RRC signaling. DCI 4-1 can be used when RRC signaling is ambiguous or the channel quality is poor. In this way, if a new parameter is added to DCI 4-1, this practice is unacceptable because it will cause the size of DCI 4-1 to change. For DCI format 4-2, their size is larger and can change. For example, the size of the parameters they contain can be configured by RRC signaling. The presence or absence of each parameter in DCI 4-2 can also be configured by RRC signaling. The DCI format for downlink multicast transmission can be used to activate an SPS configuration for multicast.

[0044] FIG1 is a flow chart of a method for determining parameters of an SPS configuration in an embodiment of the present application. As shown in FIG1 , the method includes the following steps:

[0045] S110 : In response to the SPS configuration, the device determines two parameter values ​​for one or more parameter types in the SPS configuration.

[0046] Among them, the parameter types in the SPS configuration include: time domain resource allocation TDRA, modulation and coding mode MCS, frequency domain resource allocation FDRA, mapping method of virtual resource blocks VRB to physical resource blocks PRB, transmission power control command TPC, and timing interval from transmission channel to HARQ-ACK.

[0047] The device may be a base station or a user equipment (UE). The base station determines two parameter values ​​for one or more parameter types in the SPS configuration, configures the two parameter values ​​to the UE in the following manner, and performs corresponding transmission or reception according to the two parameter values. The UE determines two parameter values ​​for one or more parameter types in the SPS configuration, based on relevant configuration information sent by the base station in the following manner, and performs corresponding transmission or reception according to the two determined parameter values.

[0048] In one embodiment, the method for determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining a TDRA parameter based on the physical uplink control channel resource indication PRI and / or downlink allocation indication DAI in the downlink control information DCI corresponding to the SPS configuration, and associating the TDRA parameter with a first type of orthogonal frequency division multiplexing (OFDM) symbol or a second type of OFDM symbol; indicating another TDRA parameter with the original TDRA parameter in the DCI, and associating the TDRA parameter with the second type of OFDM symbol or the first type of OFDM symbol.

[0049] 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 resources includes a sub-band full-duplex SBFD sub-band or a co-frequency simultaneous full-duplex CCFD sub-band.

[0050] In this embodiment, the PRI and / or DAI in the DCI for activating the SPS configuration is used to determine a TDRA parameter, and the TDRA parameter is associated with the first type OFDM symbol (or the second type OFDM symbol). The original TDRA parameter in the DCI indicates another TDRA parameter, and the TDRA parameter is associated with the second type OFDM symbol (or the first type OFDM symbol). In this way, the activated SPS configuration will be associated with two TDRA parameters in the DCI. If the transmission timing of an SPS PDSCH configured by the SPS is in the first type OFDM symbol, the TDRA parameter associated with the first type OFDM symbol is used for the SPS PDSCH. If the transmission timing of an SPS PDSCH configured by the SPS is in the second type OFDM symbol, the TDRA parameter associated with the first type OFDM symbol is used for the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a TDRA parameter, and the TDRA parameter is used when the SPS PDSCH of the SPS configuration is transmitted in an SBFD symbol (or in a non-SBFD symbol).

[0051] Optionally, the method of determining a TDRA parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration may include at least one of the following: the PRI and / or DAI in the DCI corresponding to the SPS configuration indicates a TDRA parameter in the time domain resource set; or, determining a TDRA parameter in the time domain resource set based on the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration.

[0052] Among them, the offset is the offset between the original TDRA parameter in the DCI. The time domain resource set is the time domain resource set corresponding to the first type of OFDM symbol, or the time domain resource set corresponding to the second type of OFDM symbol, or the time domain resource set shared by the first type of OFDM symbol and the second type of OFDM symbol. Specifically, the method of determining a TDRA parameter in the time domain resource set according to the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration can be: adding (or subtracting) the offset to the original TDRA parameter in the DCI. The offset (offset) includes positive and negative values, and the value of the offset can be discontinuous, including equal intervals (for example, {-4, -2, 0, 2, 4, 6}) or non-equal intervals (for example, {-4, -3, 0, 1, 2, 3}). This method is conducive to reducing the offset overhead, for example, only the PRI is used.

[0053] Optionally, if the DCI is used to activate the SPS configuration, the base station and the UE consider a TDRA parameter indicated by the TDRA parameter in the DCI, both when the SPS PDSCH of the SPS configuration is transmitted in the first type of OFDM symbol and when the SPS PDSCH of the SPS configuration is transmitted in the second type of OFDM symbol. Furthermore, the same or different PDSCH time domain resource sets (or subcarrier spacing SCS) can be configured for the first type of OFDM symbol and the second type of OFDM symbol.

[0054] In one embodiment, the method for determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining an MCS parameter based on the PRI and / or DAI in the corresponding DCI of the SPS configuration, and associating the MCS parameter with the first type of OFDM symbol or the second type of OFDM symbol; indicating another MCS parameter with the original MCS parameter in the DCI, and associating the MCS parameter with the second type of OFDM symbol or the first type of OFDM symbol.

[0055] In this embodiment, the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine an MCS parameter, and the MCS parameter is associated with the first type OFDM symbol (or the second type OFDM symbol). The original MCS parameter in the DCI indicates another MCS parameter, and the MCS parameter is associated with the second type OFDM symbol (or the first type OFDM symbol). In this way, the activated SPS configuration will be associated with two MCS parameters in the DCI. If the transmission timing of an SPS PDSCH of the SPS configuration is in the first type OFDM symbol, the MCS parameter associated with the first type OFDM symbol is used for the SPS PDSCH. If the transmission timing of an SPS PDSCH of the SPS configuration is in the second type OFDM symbol, the MCS parameter associated with the first type OFDM symbol is used for the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine an MCS parameter, and the MCS parameter is used when the SPS PDSCH of the SPS configuration is transmitted in an SBFD symbol (or in a non-SBFD symbol).

[0056] Optionally, the method of determining an MCS parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration includes at least one of the following: the PRI and / or DAI in the DCI corresponding to the SPS configuration indicates an MCS parameter in the MCS table; or, determining an MCS parameter in the MCS table based on the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration.

[0057] The offset is the offset from the original MCS parameter in the DCI. The MCS table is the MCS table corresponding to the first type of OFDM symbol, or the MCS table corresponding to the second type of OFDM symbol, or the MCS table shared by the first type of OFDM symbol and the second type of OFDM symbol. Specifically, the method of determining an MCS parameter in the MCS table according to the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration can be: adding (or subtracting) the offset to the original MCS parameter in the DCI. The offset includes positive and negative values, and the value of the offset can be discontinuous, including equal intervals (for example, {-4, -2, 0, 2, 4, 6}) or non-equal intervals (for example, {-4, -3, 0, 1, 2, 3}). This method is conducive to reducing the offset overhead, for example, only the PRI is used.

[0058] Optionally, if the DCI is used to activate the SPS configuration, the base station and the UE consider an MCS parameter indicated by the MCS parameter in the DCI, both when the SPS PDSCH of the SPS configuration is transmitted in the first type of OFDM symbols and when the SPS PDSCH of the SPS configuration is transmitted in the second type of OFDM symbols. Furthermore, the same or different MCS tables (or subcarrier spacings SCS) can be configured for the first type of OFDM symbols and the second type of OFDM symbols.

[0059] In one embodiment, the method of determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining an FDRA parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration, and the FDRA parameter is used to transmit in the first type of OFDM symbol or the second type of OFDM symbol; indicating the original FDRA parameter in the DCI to another FDRA parameter, and the FDRA parameter is used to transmit in the second type of OFDM symbol or the first type of OFDM symbol.

[0060] In this embodiment, the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine an FDRA parameter, and the FDRA parameter is associated with the first type OFDM symbol (or the second type OFDM symbol). The original FDRA parameter in the DCI indicates another FDRA parameter, and the FDRA parameter is associated with the second type OFDM symbol (or the first type OFDM symbol). In this way, the activated SPS configuration will be associated with two FDRA parameters in the DCI. If the transmission timing of an SPS PDSCH of the SPS configuration is in the first type OFDM symbol, the FDRA parameter associated with the first type OFDM symbol is used for the SPS PDSCH. If the transmission timing of an SPS PDSCH of the SPS configuration is in the second type OFDM symbol, the FDRA parameter associated with the first type OFDM symbol is used for the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine an FDRA parameter, and the FDRA parameter is used when the SPS PDSCH of the SPS configuration is transmitted in an SBFD symbol (or in a non-SBFD symbol).

[0061] Optionally, the method of determining an FDRA parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration includes at least one of the following: the PRI and / or DAI in the DCI corresponding to the SPS configuration indicates an FDRA parameter; or, determining an FDRA parameter based on the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration.

[0062] Among them, the offset is the offset between the original FDRA parameter in the DCI. The method of determining an FDRA parameter according to the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration can be: adding (or subtracting) the offset to the original FDRA parameter in the DCI. The offset (offset) includes positive and negative values, and the value of the offset can be discontinuous, including equal intervals (for example, {-4, -2, 0, 2, 4, 6}) or non-equal intervals (for example, {-4, -3, 0, 1, 2, 3}). This method is conducive to reducing the overhead of the offset, for example, only the PRI is used.

[0063] Optionally, if the DCI is used to activate the SPS configuration, the base station and the UE consider an FDRA parameter indicated by the FDRA parameter in the DCI, both when the SPS PDSCH of the SPS configuration is transmitted in the first type of OFDM symbol and when the SPS PDSCH of the SPS configuration is transmitted in the second type of OFDM symbol. Furthermore, the same or different RBG for PDSCH RA type 0 (or PRG for PDSCH, or subcarrier spacing SCS) can be configured for the first type of OFDM symbol and the second type of OFDM symbol.

[0064] In one embodiment, the method for determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining a VRB to PRB mapping parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration, and the VRB to PRB mapping parameter is used to transmit in the first type of OFDM symbol or the second type of OFDM symbol; indicating the original VRB to PRB mapping parameter in the DCI to another VRB to PRB mapping parameter, and the VRB to PRB mapping parameter is used to transmit in the second type of OFDM symbol or the first type of OFDM symbol.

[0065] In this embodiment, the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a VRB-to-PRB mapping parameter, and the VRB-to-PRB mapping parameter is associated with the first type of OFDM symbol (or the second type of OFDM symbol). The original VRB-to-PRB mapping parameter in the DCI indicates another VRB-to-PRB mapping parameter, and the VRB-to-PRB mapping parameter is associated with the second type of OFDM symbol (or the first type of OFDM symbol). In this way, the activated SPS configuration will be associated with two VRB-to-PRB mapping parameters in the DCI. If the transmission timing of an SPS PDSCH of the SPS configuration is in the first type of OFDM symbol, the VRB-to-PRB mapping parameter associated with the first type of OFDM symbol is used for the SPS PDSCH. If the transmission timing of an SPS PDSCH of the SPS configuration is in the second type of OFDM symbol, the VRB-to-PRB mapping parameter associated with the first type of OFDM symbol is used for the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a VRB to PRB mapping parameter, and the VRB to PRB mapping parameter is used when the SPS PDSCH of the SPS configuration is transmitted in an SBFD symbol (or in a non-SBFD symbol).

[0066] Optionally, the method of determining a VRB to PRB mapping parameter according to the PRI and / or DAI in the DCI corresponding to the SPS configuration may be: indicating the PRI and / or DAI in the DCI corresponding to the SPS configuration as a VRB to PRB mapping parameter. The VRB to PRB mapping parameter is transmitted in a first type OFDM symbol (or second type OFDM symbol) in an SPS PDSCH of the SPS configuration.

[0067] If the DCI is used to activate an SPS configuration, the base station and the UE shall consider that the VRB-to-PRB mapping indicated by the VRB-to-PRB mapping parameter in the DCI is used both when the SPS PDSCH of the SPS configuration is transmitted in SBFD symbols and when the SPS PDSCH of the SPS configuration is transmitted in non-SBFD symbols.

[0068] In one embodiment, the method for determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining a TPC parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration, and associating the TPC parameter with the first type of OFDM symbol or the second type of OFDM symbol; indicating the original TPC parameter in the DCI to another TPC parameter, and associating the TPC parameter with the second type of OFDM symbol or the first type of OFDM symbol.

[0069] In this embodiment, the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a TPC parameter, and the TPC parameter is associated with the first type OFDM symbol (or the second type OFDM symbol). The original TPC parameter in the DCI indicates another TPC parameter, and the TPC parameter is associated with the second type OFDM symbol (or the first type OFDM symbol). In this way, the activated SPS configuration will be associated with two TPC parameters in the DCI. If the HARQ-ACK PUCCH of an SPS PDSCH of the SPS configuration is in the first type OFDM symbol, the TPC parameter associated with the first type OFDM symbol is used for the HARQ-ACK PUCCH of the SPS PDSCH. If the HARQ-ACK PUCCH of an SPS PDSCH of the SPS configuration is in the second type OFDM symbol, the TPC parameter associated with the first type OFDM symbol is used for the HARQ-ACK PUCCH of the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a TPC parameter, and the TPC parameter is used when the HARQ-ACK PUCCH of the SPS PDSCH of the SPS configuration is transmitted in the SBFD symbol (or in the non-SBFD symbol).

[0070] Optionally, the method of determining a TPC parameter based on the PRI and / or DAI in the DCI corresponding to the SPS configuration includes at least one of the following: the PRI and / or DAI in the DCI corresponding to the SPS configuration indicates a TPC parameter in the TPC table; or, determining a TPC parameter in the TPC table based on the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration.

[0071] The offset is the offset from the original TPC parameter in the DCI. The TPC table is a TPC table corresponding to the first type of OFDM symbol, or a TPC table corresponding to the second type of OFDM symbol, or a TPC table shared by the first type of OFDM symbol and the second type of OFDM symbol. Specifically, the method of determining a TPC parameter in the TPC table according to the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration can be: adding (or subtracting) the offset to the original TPC parameter in the DCI. The offset includes positive and negative values, and the value of the offset can be discontinuous, including equal intervals (for example, {-4, -2, 0, 2, 4, 6}) or non-equal intervals (for example, {-4, -3, 0, 1, 2, 3}). This method is conducive to reducing the offset overhead, for example, only the PRI is used.

[0072] Optionally, if the DCI is used to activate the SPS configuration, the base station and the UE consider a TPC parameter indicated by the TPC parameter in the DCI, both when the HARQ-ACK PUCCH of the SPS PDSCH of the SPS configuration is transmitted in the first type of OFDM symbol and when the HARQ-ACK PUCCH of the SPS PDSCH of the SPS configuration is transmitted in the second type of OFDM symbol. Furthermore, the same or different TPC tables (or subcarrier spacings SCS) can be configured for the first type of OFDM symbols and the second type of OFDM symbols.

[0073] In one embodiment, the method for determining two parameter values ​​for one or more parameter types in the SPS configuration can be: determining a timing interval parameter from a transmission channel to HARQ-ACK based on the PRI and / or DAI in the DCI corresponding to the SPS configuration, and associating the timing interval parameter from the transmission channel to HARQ-ACK with the first type of OFDM symbol or the second type of OFDM symbol; indicating the timing interval parameter from the original transmission channel to HARQ-ACK in the DCI to the timing interval parameter from another transmission channel to HARQ-ACK, and associating the timing interval parameter from the transmission channel to HARQ-ACK with the second type of OFDM symbol or the first type of OFDM symbol.

[0074] In this embodiment, the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a timing interval parameter from a transport channel to HARQ-ACK, and the timing interval parameter from the transport channel to HARQ-ACK is associated with a first type of OFDM symbol (or a second type of OFDM symbol). The original timing interval parameter from the transport channel to HARQ-ACK in the DCI indicates a timing interval parameter from another transport channel to HARQ-ACK, and the timing interval parameter from the transport channel to HARQ-ACK is associated with a second type of OFDM symbol (or a first type of OFDM symbol). In this way, the activated SPS configuration will be associated with two timing interval parameters from the transport channel to HARQ-ACK in the DCI. If the transmission timing of an SPS PDSCH of the SPS configuration is in a first type of OFDM symbol, the timing interval parameter from the transport channel to HARQ-ACK associated with the first type of OFDM symbol is used for the SPS PDSCH. If an SPS PDSCH transmission opportunity of the SPS configuration is in a second type OFDM symbol, the transport channel to HARQ-ACK timing interval parameter associated with the first type OFDM symbol is used for the SPS PDSCH. For example, if a UE is configured with an SBFD subband and is configured with an SPS configuration based on option 2 above, the base station and the UE agree that the PRI and / or DAI in the DCI used to activate the SPS configuration is used to determine a transport channel to HARQ-ACK timing interval parameter, and the transport channel to HARQ-ACK timing interval parameter is used when the SPS PDSCH of the SPS configuration is transmitted in an SBFD symbol (or in a non-SBFD symbol).

[0075] Optionally, the method of determining a timing interval parameter from a transmission channel to HARQ-ACK based on the PRI and / or DAI in the DCI corresponding to the SPS configuration may include at least one of the following: the PRI and / or DAI in the DCI corresponding to the SPS configuration indicates a timing interval parameter from a transmission channel to HARQ-ACK in a timing interval set from the transmission channel to HARQ-ACK; or, determining a timing interval parameter from a transmission channel to HARQ-ACK in a timing interval set from the transmission channel to HARQ-ACK based on an offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration.

[0076] Among them, the offset is the offset between the timing interval parameter from the original transport channel to HARQ-ACK in the DCI. The timing interval set from the transport channel to HARQ-ACK is the timing interval set from the transport channel to HARQ-ACK corresponding to the first type of OFDM symbol, or the timing interval set from the transport channel to HARQ-ACK corresponding to the second type of OFDM symbol, or the timing interval set from the transport channel to HARQ-ACK shared by the first type of OFDM symbol and the second type of OFDM symbol. Specifically, the method of determining the timing interval parameter from a transport channel to HARQ-ACK in the time domain resource set according to the offset indicated by the PRI and / or DAI in the DCI corresponding to the SPS configuration can be: adding (or subtracting) the offset to the timing interval parameter from the original transport channel to HARQ-ACK in the DCI. The offset includes positive and negative values, and the value of the offset can be discontinuous, including equal intervals (for example, {-4, -2, 0, 2, 4, 6}) or non-equal intervals (for example, {-4, -3, 0, 1, 2, 3}). This method is helpful in reducing the offset overhead, for example, only the PRI is used.

[0077] Optionally, if the DCI is used to activate the SPS configuration, the base station and the UE consider the transmission channel to HARQ-ACK timing interval parameter indicated by the transmission channel to HARQ-ACK timing interval parameter in the DCI, both when the SPS PDSCH of the SPS configuration is transmitted in the first type of OFDM symbol and when the SPS PDSCH of the SPS configuration is transmitted in the second type of OFDM symbol. Furthermore, the same or different PDSCH time domain resource sets (or subcarrier spacing SCS) can be configured for the first type of OFDM symbol and the second type of OFDM symbol.

[0078] In the above embodiment, the PRI and / or DAI in the DCI are used to determine an additional parameter. However, since the parameters that can be reinterpreted in the DCI are limited, in the above embodiment, only one additional parameter can be determined based on the reinterpretation of the PRI and / or DAI in the DCI. For example, an additional MCS is determined by reinterpreting the PRI and / or DAI in the DCI. This additional MCS is used when the SPS PDSCH of the above SPS configuration is transmitted in SBFD symbols; while the original MCS in DCI1-0 can be used when the SPS PDSCH of the above SPS configuration is transmitted in the first type of OFDM symbols. In this way, two MCSs can be obtained through DCI and used separately for the above SPS configuration. However, in addition to the MCS, for an SPS configuration, two other parameters (e.g., TDRA, FDRA, VRB to PRB mapping, TPC, PDSCH to HARQ-ACK timing interval, etc.) are also required. These two parameters are used for the SPS PDSCH in the first type of OFDM symbols and the second type of OFDM symbols, respectively.

[0081] In this embodiment, if the SPS configuration is activated, when an SPS PDSCH of the SPS configuration is transmitted in a first type OFDM symbol, the first TDRA parameter is used in the SPS PDSCH; when another SPS PDSCH of the SPS configuration is transmitted in a second type OFDM symbol, the second TDRA parameter is used in the SPS PDSCH.

[0082] In this embodiment, a TDRA parameter associated with a first type of OFDM symbol and another TDRA parameter associated with a second type of OFDM symbol are configured in the RRC signaling of the SPS configuration, and the manner of recording them as the first TDRA parameter and the second TDRA parameter, respectively, includes at least one of the following: if the first TDRA parameter or the second TDRA parameter is defaulted in the RRC signaling of the SPS configuration, the default first TDRA parameter or the second TDRA parameter is determined according to the TDRA parameter in the DCI used to activate the SPS configuration. If the first TDRA parameter or the second TDRA parameter is defaulted in the RRC signaling of the SPS configuration, the default TDRA parameter is determined according to the TDRA parameter that is not defaulted in the RRC signaling.

If the first MCS parameter or the second MCS parameter is defaulted in the RRC signaling of the SPS configuration, the default MCS parameter is determined according to the MCS parameter that is not defaulted in the RRC signaling. If the first MCS parameter and the second MCS parameter are defaulted in the RRC signaling of the SPS configuration, the default first MCS parameter and the second MCS parameter are determined according to the MCS parameter in the DCI used to activate the SPS configuration.
