Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0104] In some embodiments, the network device can configure the terminal with an uplink subband in a downlink time unit or in a flexible time unit. The time units configured with the uplink subband can be referred to as subband full duplex (SBFD) time units, and the time units not configured with the uplink subband can be referred to as non-SBFD (also referred to as non-SBFD) time units.

[0105] In some embodiments, the network device can configure the terminal with a downlink subband in an uplink time unit or in a flexible time unit. The time units configured with the downlink subband can be referred to as SBFD time units, and the time units not configured with the downlink subband can be referred to as non-SBFD time units.

[0106] The disclosure is not limited to time units, for example, at least one of the following can be included: frame, subframe, slot, symbol, sub-slot. The symbol can be, for example, an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0107] For example, for the SBFD time unit configured with the uplink subband, the network device can receive the information sent by the terminal in the uplink subband of the SBFD time unit, and send information to the terminal in the frequency domain resource outside the uplink subband corresponding to the SBFD time unit, so that the network device can realize full duplex communication in the SBFD time unit.

[0108] FIG. 1B is a schematic diagram of a subband according to an embodiment of the disclosure.

[0109] As shown in FIG. 1B, taking 5 slots slot#n to slot#n+4 as an example, the slot structure pattern of the 5 slots is DFFFU, where D represents that the corresponding slot is a downlink slot, F represents that the corresponding slot is a flexible slot, and U represents that the corresponding slot is an uplink slot.

[0110] The network device can configure the uplink subband in the frequency domain resource corresponding to slot#n+1 to slot#n+3. In the case that slot#n+1 to slot#n+3 are used for downlink transmission, the network device can perform uplink transmission in the uplink subband corresponding to the 3 slots, and perform downlink transmission in the frequency domain resource (for example, referred to as a downlink subband) outside the uplink subband corresponding to the 3 slots, so that full duplex communication can be realized in the 3 slots configured with the uplink subband.

[0111] In some embodiments, a guard band (GB) can also be arranged between the uplink sub-band and the downlink sub-band to realize frequency domain isolation of the uplink sub-band and the downlink sub-band.

[0112] It should be noted that, in the time domain unit configured with the sub-band, although the network device can realize full duplex communication, the terminal can only perform half duplex communication, that is, can only perform uplink communication or downlink communication in a single time domain unit.

[0113] In some embodiments, in the communication process, the transmission (such as uplink transmission, downlink transmission, etc.) between the network device and the terminal can be performed on the SBFD time unit or the non-SBFD time unit, and in this case, the transmission needs to be based on the power control parameter.

[0114] In some embodiments, in the SBFD time unit, the network device needs to perform uplink communication and downlink communication, and in the non-SBFD time unit, the network device only needs to perform uplink communication or downlink communication. Therefore, for the transmission on the SBFD time unit and the non-SBFD time unit, the antenna, transmission environment, interference condition, etc. configured by the network device are different, and the corresponding power control parameter needs to be based on the corresponding power control parameter to facilitate meeting the communication requirements.

[0115] FIG. 2 is an interaction schematic diagram of a parameter determination method according to an embodiment of the present disclosure.

[0116] In some embodiments, the terminal determines the SBFD time unit and the non-SBFD time unit.

[0117] For example, the terminal can determine that the time unit configured with the sub-band is the SBFD time unit, and the time unit not configured with the sub-band is the non-SBFD time unit (that is, the traditional time unit).

[0118] In some embodiments, the terminal can determine at least one power control parameter.

[0119] For example, the at least one power control parameter can include one or more types of power control parameters, and for a single type, one or more power control parameters can be corresponded.

[0120] It should be noted that the at least one power control parameter determined by the terminal can be determined based on a predefined rule (such as a protocol agreement) or based on network device indication, and the present disclosure does not limit this.

[0121] In step S201, at least one of the power control parameters in the at least one power control parameter is determined according to the predefined rule or the indication information:

[0122] The transmission between the terminal and the network device is based on a first power control parameter corresponding to the SBFD time unit;

[0123] The transmission is based on a second power control parameter corresponding to the non-SBFD time unit.

[0124] In step S202, the terminal can perform transmission using the corresponding power control parameter on the SBFD time unit and / or the non-SBFD time unit.

[0125] According to an embodiment of the present disclosure, for the transmission between the network device and the terminal, the corresponding power control parameters on the SBFD time unit and the non-SBFD time unit can be determined respectively, so that the terminal can perform transmission on the SBFD time unit based on the corresponding power control parameter of the resource on the SBFD time unit, and perform transmission on the non-SBFD time unit based on the corresponding power control parameter of the resource on the non-SBFD time unit, so as to meet the communication requirements on the SBFD time unit and the non-SBFD time unit.

[0126] In some embodiments, the terminal can determine the time unit in which the transmission is located.

[0127] For example, the time unit in which the transmission is located can include at least one of the SBFD time unit and the non-SBFD time unit.

[0128] For example, the transmission parameter corresponding to the SBFD time unit is recorded as a first transmission parameter set (which can include one or more transmission parameters), and the transmission parameter corresponding to the non-SBFD time unit is recorded as a second transmission parameter set (which can include one or more transmission parameters).

[0129] In the case of transmission on the SBFD time unit, the terminal can perform transmission based on the transmission parameters in the first transmission parameter set;

[0130] In the case of transmission on the non-SBFD time unit, the terminal can perform transmission based on the transmission parameters in the second transmission parameter set.

[0131] In some embodiments, the terminal can directly determine the time unit in which the transmission is located according to the indication of the network device; or the terminal can indirectly determine the time unit in which the transmission is located according to the scheduling information used to schedule the transmission, for example, if the scheduling information is located in the SBFD time unit, the terminal can determine that the transmission scheduled by the scheduling information is also in the SBFD time unit, for example, if the scheduling information is located in the non-SBFD time unit, the terminal can determine that the transmission scheduled by the scheduling information is also in the non-SBFD time unit.

[0132] In some embodiments, the terminal can determine the time domain location of the SBFD time unit based on the network device configuration and corresponding rules. In the case that the terminal transmits data on the SBFD time unit based on the scheduling, the terminal determines that the data transmission corresponds to the SBFD time unit.

[0133] Taking the transmission of PUSCH including DCI scheduling as an example, if the terminal determines that the PUSCH is transmitted on the transmission occasion i based on the DCI scheduling information.

[0134] If the terminal determines that the occasion i corresponds to the SBFD time unit based on the network device configuration and corresponding rules, the terminal determines that the PUSCH is transmitted on the SBFD time unit. For example, the transmission corresponds to the UL subband frequency domain range.

[0135] If the terminal determines that the occasion i is non-SBFD based on the network device configuration or corresponding predefined rules, the terminal determines that the PUSCH is transmitted on the non-SBFD time unit. For example, the transmission corresponds to the UL BWP frequency domain range.

[0136] Corresponding to the uplink data transmitted on the occasion i, if the occasion i contains both the SBFD time unit and the non-SBFD time unit, the terminal determines the time unit type corresponding to the occasion i based on at least one of the following manners:

[0137] The terminal determines that the occasion i corresponds to the SBFD time unit, or the terminal determines that the occasion i corresponds to the non-SBFD time unit.

[0138] The terminal determines the time unit type corresponding to the occasion i based on the first time unit corresponding to the occasion i. For example, if the first time unit is the SBFD time unit, the terminal determines that the time unit type corresponding to the occasion i is SBFD; if the first time unit is the non-SBFD time unit, the terminal determines that the time unit type corresponding to the occasion i is non-SBFD.

[0139] The terminal determines that the occasion i corresponds to both the SBFD time unit and the non-SBFD time unit.

[0140] If the occasion i contains both the SBFD time unit and the non-SBFD time unit, the terminal performs unified power control mechanism for different time unit types. For example, the corresponding power control parameters are determined by using the traditional mechanism.

[0141] In some embodiments, a transmission occasion i can be defined by an index of a slot within a frame corresponding to a system frame number (SFN), e.g., a first symbol S in the slot, and a length L of the symbol. For PUSCH repetition transmission of Type B, one PUSCH transmission occasion is one nominal repetition, e.g., refer to 3GPP protocol [6, TS 38.214].

[0142] In some embodiments, the power control parameter comprises at least one of:

[0143] The closed loop power control index l, which can also be referred to as a data power control adjustment state index, e.g., the value can be 1 or 0, and the data can comprise PUSCH, PUCCH, SRS, etc. transmission;

[0144] The closed loop power control parameter f b,f,c (i, l), e.g., for uplink transmission PUSCH, in the case of accumulated closed loop power control type, or, in the case of absolute closed loop power control type, f b,f,c (i, l) = δPUSCH,b,f,c(i, l), where the subscript c denotes a serving cell, f denotes a carrier frequency, b denotes a bandwidth part, and i denotes a transmission occasion.

[0145] The parameter δ in the above f b,f,c (i, l) can be indicated by a TPC information field.

[0146] For example, there can be multiple types of power control parameters, e.g., absolute closed loop power control parameter, accumulated closed loop power control parameter, etc.

[0147] The related meanings of the closed loop power control index and the closed loop power control parameter are described in subsequent embodiments, which are not expanded here.

[0148] In some embodiments, the power control parameter can be configured by a network device. The network device can configure the power control parameter for the terminal through system information, RRC (Radio Resource Control) signaling, MAC CE (Media Access Control Control Element), DCI (Downlink Control Information), etc. signaling.

[0149] Further, for example, the network device can indicate the power control parameter through an IE (Information Element) or field in the signaling.

[0150] It should be noted that the signaling for indicating the power control parameter can reuse the signaling of the conventional function, or can define a signaling dedicated to the SBFD scenario, for example, denoted as SBFD specific signaling.

[0151] Taking an example that at least one power control parameter includes two power control parameters, and the power control parameters are configured through RRC signaling or system information, the two power control parameters indicated by the network device can be different based on the specific parameter type, for example, can include:

[0152] SRI-PUSCH-MappingToAddModList1 and SRI-PUSCH-MappingToAddModList2, SRI stands for SRS resource indication (SRS resource indication), the transmission parameters in the two transmission parameter sets can be one or more, including but not limited to a path loss reference signal, a path loss adjustment coefficient, a power control parameter index, and a target received power;

[0153] p0-PUSCH-Alpha and p0-PUSCH-Alpha2, the two power control parameters include a terminal transmission power and a path loss adjustment coefficient;

[0154] pathlossReferenceIndex and pathlossReferenceIndex2, the two power control parameters are path loss reference signal resource indexes;

[0155] powerControlLoopToUse and powerControlLoopToUse2, the transmission parameters in the two transmission parameter sets are power control parameter indexes;

[0156] spatialRelationInfoToAddModList and spatialRelationInfoToAddModList2, the transmission parameters in the two transmission parameter sets are spatial relations and / or power control parameters.

[0157] Take the configuration of power control parameters by RRC signaling and MAC CE as an example. RRC signaling can be used to indicate power control parameters, such as spatialRelationInfoToAddModList and spatialRelationInfoToAddModList2. MAC CE can be used to indicate transmission parameters in spatialRelationInfoToAddModList and spatialRelationInfoToAddModList2, such as indicating the first transmission parameter corresponding to the transmission on the SBFD time unit in spatialRelationInfoToAddModList, and indicating the second transmission parameter corresponding to the transmission on the non-SBFD time unit in spatialRelationInfoToAddModList2.

[0158] Take the configuration of power control parameters by RRC signaling and DCI as an example. RRC signaling can be used to indicate power control parameters, such as SRI-PUSCH-MappingToAddModList and SRI-PUSCH-MappingToAddModList2. DCI can be used to indicate power control parameters in SRI-PUSCH-MappingToAddModList and SRI-PUSCH-MappingToAddModList2, such as indicating the first power control parameter corresponding to the transmission on the SBFD time unit in SRI-PUSCH-MappingToAddModList, and indicating the second power control parameter corresponding to the transmission on the non-SBFD time unit in SRI-PUSCH-MappingToAddModList2.

[0159] Take the indication of power control parameters by RRC signaling as an example, such as powerControlLoopToUse and powerControlLoopToUse2, the terminal can determine the closed-loop power control index l accordingly, such as determining the closed-loop power control index l corresponding to the transmission on the SBFD time unit based on powerControlLoopToUse, and determining the closed-loop power control index l corresponding to the transmission on the non-SBFD time unit based on powerControlLoopToUse2.

[0160] Taking the DCI indication of the power control parameter as an example. For example, the power control parameter includes a closed loop power control index. The DCI can indicate the corresponding first closed loop power control index of the transmission on the SBFD time unit and the corresponding second closed loop power control index of the transmission on the non-SBFD time unit through the closed loop indicator. For example, the power control parameter includes a parameter δ. The DCI can indicate the corresponding first parameter δ of the transmission on the SBFD time unit and the corresponding second parameter δ of the transmission on the non-SBFD time unit through the TPC (Transmit power control) information field. The first parameter δ and the second parameter δ can correspond to different values or the same value, and the present disclosure does not limit this.

[0161] In some embodiments, the at least one power control parameter includes a first closed loop power control index and a second closed loop power control index, and the predefined rule includes one of the following:

[0162] The first closed loop power control index is a closed loop power control index applied to the SBFD time unit, and the second closed loop power control index is a closed loop power control index corresponding to the transmission on the non-SBFD time unit. For example, the first closed loop power control index l=0, and the second closed loop power control index l=1. Then, l=0 is applied to the SBFD time unit, and l=1 is applied to the non-SBFD time unit.

[0163] The first closed loop power control index is a closed loop power control index applied to the non-SBFD time unit, and the second closed loop power control index is a closed loop power control index corresponding to the transmission on the SBFD time unit. For example, the first closed loop power control index l=0, and the second closed loop power control index l=1. Then, l=0 is applied to the non-SBFD time unit, and l=0 is applied to the SBFD time unit.

[0164] The first closed loop power control index is a closed loop power control index applied to the SBFD time unit and the non-SBFD time unit. For example, the first closed loop power control index l=0. Then, l=0 is applied to the SBFD time unit and the non-SBFD time unit.

[0165] The second closed loop power control index is a closed loop power control index applied to the SBFD time unit and the non-SBFD time unit. For example, the second closed loop power control index l=1. Then, l=1 is applied to the SBFD time unit and the non-SBFD time unit.

[0166] In some embodiments, the at least one power control parameter includes a first closed loop power control index and a second closed loop power control index, and the indication information is used to indicate at least one of the following:

[0167] The first closed loop power control index is the closed loop power control index applied on SBFD time unit, and the second closed loop power control index is the closed loop power control index corresponding to transmission on non-SBFD time unit; for example, the first closed loop power control index l=0, and the second closed loop power control index l=1, then l=0 is applied to the SBFD time unit, and l=1 is applied to the non-SBFD time unit;

[0168] The first closed loop power control index is the closed loop power control index applied on non-SBFD time unit, and the second closed loop power control index is the closed loop power control index corresponding to transmission on SBFD time unit; for example, the first closed loop power control index l=0, and the second closed loop power control index l=1, then l=0 is applied to the non-SBFD time unit, and l=0 is applied to the SBFD time unit;

[0169] The first closed loop power control index is the closed loop power control index applied on SBFD time unit and non-SBFD time unit; for example, the first closed loop power control index l=0, and the second closed loop power control index l=1, then l=0 is applied to the non-SBFD time unit, and l=0 is applied to the SBFD time unit;

[0170] The second closed loop power control index is the closed loop power control index applied on SBFD time unit and non-SBFD time unit; for example, the second closed loop power control index l=1, then l=1 is applied to the SBFD time unit and the non-SBFD time unit.

[0171] In some embodiments, in the case that the terminal indicates the l∈{0,1} through RRC signaling, for example, based on the RRC signaling twoPUSCH-PC-AdjustmentStates to indicate that the value of l is 0 or 1. In the SFBD scenario, for the transmission occasion (for example, PUSCH) related to the SBFD time unit, l=0, and for the transmission occasion related to the non-SBFD time unit, l=1. The translation of this content is as follows, for example:

[0172] l∈{0,1}if the UE is configured with twoPUSCH-PC-AdjustmentStates.For SBFD scenario,l=0for PUSCH transmission corresponding to SBFD transmission occasion,l=1 for PUSCH transmission corresponding to non-SBFD transmission occasion.

[0173] In some embodiments, the at least one closed loop power control index comprises one closed loop power control index, and the indication information is used to indicate at least one of the following:

[0174] The closed loop power control index is a closed loop power control index applied to SBFD time units; for example, the closed loop power control index l = 1, then l = 1 is applied to SBFD time units; for example, the closed loop power control index l = 0, then l = 0 is applied to SBFD time units.

[0175] The closed loop power control index is a closed loop power control index applied to non-SBFD time units; for example, the closed loop power control index l = 1, then l = 1 is applied to non-SBFD time units; for example, the closed loop power control index l = 0, then l = 0 is applied to non-SBFD time units.

[0176] The closed loop power control index is a closed loop power control index applied to SBFD time units and non-SBFD time units; for example, the closed loop power control index l = 1, then l = 1 is applied to SBFD time units and non-SBFD time units; for example, the closed loop power control index l = 0, then l = 0 is applied to SBFD time units and non-SBFD time units.

[0177] In some embodiments, the at least one power control parameter comprises one closed loop power control index, and the pre-defined rule comprises at least one of the following:

[0178] The closed loop power control index is a closed loop power control index applied to SBFD time units; for example, the closed loop power control index l = 1, l = 1 is applied to SBFD time units; for example, the closed loop power control index l = 0, l = 0 is applied to non-SBFD time units.

[0179] The closed loop power control index is a closed loop power control index applied to non-SBFD time units; for example, the closed loop power control index l = 1, l = 1 is applied to non-SBFD time units; for example, the closed loop power control index l = 0, l = 0 is applied to non-SBFD time units.

[0180] The closed loop power control index is a closed loop power control index applied to SBFD time units and non-SBFD time units; for example, the closed loop power control index l = 1, l = 1 is applied to SBFD time units and non-SBFD time units; for example, the closed loop power control index l = 0, l = 0 is applied to SBFD time units and non-SBFD time units.

[0181] For example, after determining the correspondence between the closed loop power control index l and the time unit, in the case of accumulated closed loop power control type, if the current transmission occasion corresponds to the SBFD time unit type, the closed loop power control parameter is equal to the cumulative sum of the parameters δ corresponding to all SBFD time units in the time window; if the current transmission occasion corresponds to the non-SBFD time unit type, the closed loop power control parameter is equal to the cumulative sum of the parameters δ corresponding to all non-SBFD time units in the time window.

[0182] For example, after determining the correspondence between the closed loop power control index l and the time unit, in the case of absolute closed loop power control type, if the scheduling information scheduling the current transmission is in the SBFD time unit, the closed loop power control parameter of the transmission in the SBFD time unit is determined based on the parameter δ indicated by the scheduling information; if the scheduling information scheduling the current transmission is in the non-SBFD time unit, the closed loop power control parameter of the transmission in the non-SBFD time unit is determined based on the parameter δ indicated by the scheduling information.

[0183] In some embodiments, the at least one power control parameter does not include the closed loop power control index.

[0184] For example, the closed loop power control parameter can be determined based on the closed loop power control index, in which case the at least one closed loop power control parameter can include the closed loop power control index. For example, the closed loop power control parameter can not be determined based on the closed loop power control index, for example, indicated by the network device or specified by a predefined rule (for example, the predefined rule specifies that the closed loop power control parameter is not determined based on the closed loop power control index in a specific scenario (for example, the SBFD scenario)), in which case the at least one closed loop power control parameter can not include the closed loop power control index.

[0185] In some embodiments, taking PUSCH as an example, if the corresponding PUSCH transmission occasion corresponds to the SBFD time unit type, in the case of accumulated closed loop power control type, then for the uplink bandwidth part b of the service cell c on the carrier f and the transmission occasion i corresponding to the PUSCH transmission, the corresponding closed loop power control parameter

[0186] wherein, is the sum of the values indicated by the l(D i ) TPC commands received by the terminal on the uplink bandwidth part b of the service cell c on the carrier f between the time window t1 and t2, wherein,

[0187] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission time i-i0, N = K PUSCH (i-i0)-1;

[0188] t2 = time corresponding to M OFDM symbols before PUSCH transmission occasion i, M = K PUSCH (i);

[0189] where i0 > 0 is the smallest integer satisfying K PUSCH (i-i0) symbols before PUSCH transmission occasion i-i0 and K PUSCH (i) symbols condition.

[0190] D i a set to which the value indicated by the TPC command belongs;

[0191] is the value indicated by the m-th TPC command.

[0192] For example, the corresponding translation of this paragraph is as follows:

[0193] For SBFD occasion i, is the PUSCH power control adjustment state for active UL BWP b of carrier f of serving cell c and PUSCH transmission occasion iif the UE is not provided tpc-Accumulation.

[0194] is a sum of TPC command values in a set D i of TPC command values with cardinality C(D i )that the UEreceives between K PUSCH (i-i0)-1symbols before PUSCH transmission occasion i-i0 and K PUSCH(i) symbols before PUSCH transmission occasion i on active UL BWP b of carrier f of serving cell c for PUSCH power control adjustment state at SBFD transmission occasion m, where i0>0 is the smallest integer for which K PUSCH (i-i0) is earlier than K PUSCH (i) symbols before PUSCH transmission occasion i.

[0195] In some embodiments, taking PUSCH as an example, if the corresponding PUSCH transmission occasion corresponds to a non-SBFD time unit type, in the case of a closed-loop power control type of accumulation, then for the uplink bandwidth part b of the service cell c on the carrier f and the transmission occasion i corresponding to the PUSCH transmission, the corresponding closed-loop power control parameter

[0196] wherein, is the sum of the values indicated by the l(D i ) TPC commands received by the terminal between time windows t1 and t2 on the uplink bandwidth part b of the service cell c on the carrier f, wherein,

[0197] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission occasion i-i0, N = K PUSCH (i-i0)-1;

[0198] t2 = the time corresponding to the M OFDM symbols before the PUSCH transmission occasion i, M = K PUSCH (i);

[0199] wherein, i0>0 is the smallest integer satisfying the condition that the symbol K PUSCH (i-i0) is earlier than K PUSCH (i) symbols before PUSCH transmission occasion i.

[0200] D i is the set to which the value indicated by the TPC command belongs;

[0201] PUSCH,b,f,c(m) is the value indicated by the m-th TPC command.

[0202] For example, the corresponding translation of this paragraph is as follows:

[0203] For non-SBFD occasion i, is the PUSCH power control adjustment state for active UL BWP b of carrier f of serving cell c and PUSCH transmission occasion i if the UE is not provided tpc-Accumulation.

[0204] is a sum of TPC command values in a set D i of TPC command values with cardinality C(D i )that the UE receives between K PUSCH (i-i0)-1symbols before PUSCH transmission occasion i-i0 and K PUSCH (i)symbols before PUSCH transmission occasion i on active UL BWP b of carrier f of serving cell c for PUSCH power control adjustment state at non-SBFD transmission occasion m, where i0>0 is the smallest integer for which K PUSCH (i-i0)symbols before PUSCH transmission occasion i-i0 is earlier than K PUSCH (i)symbols before PUSCH transmission occasion i.

[0205] In some embodiments, the predefined rule comprises: determining, based on a type of a time unit in which the transmission is located, a first closed loop power control parameter corresponding to a sub-band full duplex (SBFD) time unit for the transmission, and / or a second closed loop power control parameter corresponding to a non-SBFD time unit.

[0206] In some embodiments, the closed loop power control parameter is of a first type (e.g. absolute), and the predefined rule comprises:

[0207] determining signaling used to indicate the power control parameter;

[0208] determining a type of a first time unit in which the transmission scheduled by the signaling is located;

[0209] in a case that the type comprises a SBFD time unit, determining that the closed loop power control parameter indicated by the signaling is a closed loop power control parameter corresponding to a SBFD time unit for the transmission;

[0210] in a case that the type comprises a non-SBFD time unit, determining that the closed loop power control parameter indicated by the signaling is a closed loop power control parameter corresponding to a non-SBFD time unit for the transmission.

[0211] For example, in a case that the closed loop power control parameter is of a first type (e.g. absolute), for the signaling used to indicate the closed loop power control parameter, the terminal can determine a type of a first time unit in which the transmission scheduled by the signaling is located, and then the power control parameter indicated by the signaling can be applied to the transmission on the corresponding type.

[0212] In a case that the signaling used to indicate the power control parameter comprises a DCI, the DCI can be used to indicate the power control parameter by using reserved bits, TPC information field, etc., so that the DCI can be used to indicate the power control parameter and also to schedule the transmission. The terminal can determine a type of a time unit in which the transmission scheduled by the DCI is located, e.g. the transmission scheduled by the DCI comprises a physical uplink shared channel (PUSCH).

[0213] In a case that the PUSCH scheduled by the DCI is on a SBFD time unit, the terminal can determine that the power control parameter corresponds to the SBFD time unit, so that the PUSCH can be transmitted on the SBFD time unit based on the power control parameter indicated by the DCI.

[0214] In a case that the PUSCH scheduled by the DCI is on a non-SBFD time unit, the terminal can determine that the power control parameter corresponds to the non-SBFD time unit, so that the PUSCH can be transmitted on the non-SBFD time unit based on the power control parameter indicated by the DCI.

[0215] It should be noted that the DCI-scheduled transmission can be on SBFD time units, or can be on non-SBFD time units, or can be on both SBFD time units and non-SBFD time units.

[0216] In some embodiments, the closed loop power control type of the closed loop power control parameter is the second type (e.g. accumulated), the method further comprises:

[0217] determining a time window;

[0218] determining a transmission occasion where the transmission is located;

[0219] in a case that the transmission occasion is on an SBFD time unit, determining the closed loop power control parameter f b,f,c (i, l) within the time window according to the parameters δ indicated by the signaling for the SBFD time units within the time window; b,f,c (i, l) can be determined based on the sum of the parameters δ corresponding to the SBFD time units within the time window, and can be further used to determine the power control parameter for the transmission on the SBFD time unit;

[0220] in a case that the transmission occasion is on a non-SBFD time unit, determining the closed loop power control parameter f b,f,c (i, l) within the time window according to the parameters δ indicated by the signaling for the non-SBFD time units within the time window; b,f,c (i, l) can be determined based on the sum of the parameters δ corresponding to the non-SBFD time units within the time window, and can be further used to determine the power control parameter for the transmission on the non-SBFD time unit.

[0221] For example, in a case that the closed loop power control parameter is of the second type, the terminal can determine the time window and the transmission occasion where the transmission is located, and then for the type of time unit where the transmission occasion is located, the terminal can accumulate the parameters δ corresponding to the type of time unit within the time window as the closed loop power control parameter f b,f,c (i, l), for example

[0222] It should be noted that in a case that the closed loop power control parameter is not determined based on the closed loop power control index, the closed loop power control parameter f b,f,c (i, l) can be adjusted to f b,f,c (i), in a case that the closed loop power control type is accumulated, or, in a case that the closed loop power control type is absolute, f b,f,c (i) = δPUSCH,b,f,c(i).

[0223] In some embodiments, the terminal receives signaling for indicating at least one power control parameter, wherein one first information field in the signaling is used for indicating one power control parameter. The signaling can be system information, RRC signaling, MAC CE, DCI, etc., and the present disclosure is not limited thereto.

[0224] For example, the network device can indicate at least one power control parameter through signaling, for example, the signaling includes DCI, the DCI can indicate one power control parameter set through one first information field, and when multiple power control parameter sets need to be indicated, multiple first information fields are needed to indicate. For example, the number of first information fields in the DCI is equal to the number of power control parameter sets. For example, the first information field can include a TPC information field, which can also be referred to as a TPC command information field. Of course, the first information field is not limited to the TPC information field, and can also be other information fields, and the present disclosure will not repeat them here.

[0225] It should be noted that the signaling for indicating the power control parameter is not limited to the DCI, and can also be indicated by the system information, RRC signaling, MAC CE, etc. For example, in the case of indicating the power control parameter set by the RRC signaling, the RRC signaling can be indicated by an information unit (Information Element, IE).

[0226] In some embodiments, the number of first information fields in the signaling is determined based on a predefined rule, wherein the predefined rule includes at least one of the following:

[0227] The transmission includes multiple transmissions, and the number of first information fields in the signaling is multiple;

[0228] The transmission includes one transmission, and the number of first information fields in the signaling is one.

[0229] Since the number of power control parameter sets can be one or multiple, and with the number of power control parameter sets being different, the number of first information fields will also be different, and the number of first information fields being different will result in the size (i.e., the number of bits) of the signaling where the first information field is located being different.

[0230] In the present embodiment, the terminal determines, based on the predefined rule, that the number of first information fields in the signaling is multiple in the case of multiple transmissions, for example, in the case of repetition transmission. Since the transmission includes multiple transmissions, there are different transmissions in different types of time units, and it is necessary to indicate multiple power control parameter sets corresponding to different types of time units through multiple first information fields.

[0231] In the case that the transmission includes one-time transmission, the number of the first information fields in the signaling can be determined as one. Since the transmission includes one-time transmission, there is generally no transmission in different types of time units, and thus one first information field can be used to indicate one set of power control parameters corresponding to one type of time unit.

[0232] For example, in the case that the transmission includes PUSCH, the signaling includes DCI, and the first information field includes TPC information field. In the case that the PUSCH is repeated transmission, the terminal can determine that the DCI contains multiple TPC information fields; in the case that the PUSCH is one-time transmission, the terminal can determine that the DCI contains one TPC information field. Accordingly, the terminal can accurately determine the number of information fields in the DCI, and further accurately determine the size of the DCI, so as to accurately parse the DCI based on the size.

[0233] It should be noted that the number of the first information fields in the signaling can be determined based on the predefined rule or indicated by the protocol, and the disclosure does not limit this.

[0234] In some embodiments, the transmission includes at least one of the following: uplink transmission; downlink transmission.

[0235] In some embodiments, the uplink transmission includes at least one of the following:

[0236] Physical Uplink Control Channel (PUCCH);

[0237] Physical Uplink Shared Channel (PUSCH);

[0238] Sounding Reference Signal (SRS).

[0239] In some embodiments, the downlink transmission includes at least one of the following:

[0240] Physical Downlink Control Channel (PDCCH);

[0241] Physical Downlink Shared Channel (PDSCH);

[0242] Channel State Information Reference Signal (CSI-RS);

[0243] Synchronization Signal Block (SSB).

[0244] The power control parameters are exemplarily illustrated by several embodiments as follows.

[0245] In some embodiments, the power control parameters include at least one of:

[0246] a target received power, e.g., P0;

[0247] a path loss reference signal, or a path loss reference signal resource index, e.g., q d ;

[0248] a path loss adjustment coefficient, e.g., alpha;

[0249] a closed loop power control index f b,f,c (i, l);

[0250] a parameter delta.

[0251] In some embodiments, the SRS is exemplarily taken as a transmission including uplink transmission.

[0252] For example, alpha and P0 can be determined based on SRS Resource set.

[0253] For example, q d may be configured based on RRC signaling or indicated based on MAC CE.

[0254] For example, the closed loop power control index l can correspond to a power state. When the terminal is configured with two PUSCH-PC-AdjustmentStates, l can be equal to 0 or 1; if not configured (e.g., not configured with PUSCH-PC-AdjustmentStates) or PUSCH is scheduled based on RAR UL grant, l = 0, where RAR represents Random Access Response.

[0255] For example, the value range of the closed loop power control index l can be determined based on signaling indication. For example, based on the signaling twoPUSCH-PC-AdjustmentStates indication. If the signaling indicates that the closed loop power control parameter corresponds to two states, l can be equal to 0 or 1; if the signaling does not indicate that the closed loop power control parameter corresponds to two states, or indicates that the closed loop power control parameter corresponds to one state, or corresponds to PUSCH scheduled based on RAR UL grant, l = 0, where RAR represents Random Access Response.

[0256] For example, δPUSCH,b,f,c(m,l) represents a value corresponding to the mth DCI TPC command indication in the closed loop power control state index l in a period of time. For example, the TPC indication indicates one of the indexes in Table 1 below. The terminal determines the value of δPUSCH,b,f,c(m,l) corresponding to the index indicated based on the closed loop power control type, e.g., accumulation or absolute.

[0257] Table 1

[0258] For example, the accumulated value can be accumulated δPUSCH,b,f,c(m,l) in dB, and the absolute value can be absolute δPUSCH,b,f,c(m,l) in dB.

[0259] For example, δPUSCH,b,f,c(m,l) can be used to calculate the accumulated value

[0260] The sum of the accumulated powers of δPUSCH,b,f,c(m,l) indicated by the m TPC commands corresponding to the index l in a period of time (e.g., t1 to t2). Wherein:

[0261] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission time i-i0, N = K PUSCH (i-i0)-1.

[0262] t2 = the time corresponding to the M OFDM symbols before the PUSCH transmission time i, M = K PUSCH (i).

[0263] For DCI-scheduled PUSCH, K PUSCH (i) corresponds to the number of symbols after the last symbol of the PDCCH corresponding to the DCI triggering the PUSCH transmission and before the first symbol of the PUSCH transmission.

[0264] For CG (Configured Grant) PUSCH, K PUSCH (i) corresponds to the number of symbols in each slot The product of the minimum value determined by the parameter k2 (which can be referred to in related documents, and the present disclosure does not elaborate on this parameter) and the number of symbols in each slot. For example, the k2 can be determined based on signaling indication, e.g., based on PUSCH power control configuration (PUSCH-ConfigCommon) indication.

[0265] Wherein, if the first symbol of the PUSCH transmission occasion appears T (proc,2)The UE can postpone the application of the TPC command until the time range corresponding to T (proc,2) is satisfied (T (proc,2) is satisfied (T (proc,2) is determined based on terminal capability.

For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, and steps S201 and S202 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0314] The optional implementation manners of the second aspect and the optional embodiments of the second aspect can be refer to the optional implementation manners in the embodiments shown in FIG. 2 and other associated parts in the embodiments related to FIG. 2, which will not be described herein again.

[0315] The technical solutions of the present disclosure are exemplarily described below through several embodiments.

[0316] In some embodiments, the terminal can be a legacy terminal or a Rel-18 and later version terminal, and the terminal is a terminal supporting an SBFD feature. The terminal can be configured by the base station to transmit uplink data on an UL subband on a DL or flexible symbol, and / or receive downlink data on a DL subband.

[0317] In some embodiments, a terminal supporting SBFD feature can receive downlink data on DL subband and / or transmit uplink data on UL subband based on base station configuration on UL or flexible symbol.

[0318] As mentioned above, a terminal can determine the time domain location of SBFD time unit based on base station configuration and corresponding rule. If a terminal transmits data on SBFD time unit based on scheduling, the terminal determines that the data transmission corresponds to SBFD time unit. Taking PUSCH scheduled by DCI as an example, if a terminal determines that PUSCH is transmitted on occasion i based on DCI scheduling information, the terminal determines that the PUSCH is transmitted on SBFD time unit if the terminal determines that the occasion i corresponds to SBFD time unit based on base station configuration and corresponding rule. Exemplarily, the occasion i corresponds to transmission within the frequency domain range of UL subband. On the contrary, if the terminal determines that the time unit is non-SBFD based on base station configuration or corresponding predefined rule, the terminal determines that the PUSCH is transmitted on non-SBFD time unit. Exemplarily, the occasion i corresponds to transmission within the frequency domain range of UL BWP.

[0319] Corresponding to uplink data transmitted on occasion i, if the occasion i contains both SBFD time unit and non-SBFD time unit, the terminal determines the time unit type corresponding to the occasion i based on at least one of the following manners:

[0320] The terminal determines that the occasion i corresponds to SBFD time unit, or the terminal determines that the occasion i corresponds to non-SBFD time unit.

[0321] The terminal determines the time unit type corresponding to the occasion i based on the first time unit corresponding to the occasion i. Exemplarily, if the first time unit is SBFD time unit, the terminal determines that the time unit type corresponding to the occasion i is SBFD; if the first time unit is non-SBFD time unit, the terminal determines that the time unit type corresponding to the occasion i is non-SBFD.

[0322] The terminal determines that the occasion i corresponds to both SBFD time unit and non-SBFD time unit.

[0323] Alternatively, if the occasion i contains both SBFD time units and non-SBFD time units, the terminal performs a unified power control mechanism for different time unit types. For example, the existing mechanism is used to determine the corresponding power control parameters.

[0324] As described above, in the SBFD scenario, the embodiment of the application determines the closed-loop power control parameters of the corresponding data transmission on the SBFD time unit and the non-SBFD time unit based on the pre-defined or signaling indication method.

[0325] The data transmission includes but is not limited to at least one of the following:

[0326] The uplink transmission includes but is not limited to PUSCH, SRS, PUCCH, etc.

[0327] The downlink transmission includes but is not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0328] In the following, the application is based on different embodiments, taking PUSCH transmission as an example, and the transmission parameter is the closed-loop power control parameter l, to describe the specific scheme of the application, which is used by the terminal to determine the closed-loop power control parameter of the corresponding data transmission on the SBFD time unit and / or non-SBFD time unit. It is worth noting that the corresponding data transmission can also be downlink transmission, and the transmission parameter can also be power control parameter, spatial relationship parameter set, spatial relationship parameter, etc., which is not limited by the application.

[0329] Embodiment 1:

[0330] In one possible embodiment, the terminal determines two closed-loop power control indexes (e.g., l=0, 1) based on a pre-defined rule or signaling indication method, and determines the time unit type corresponding to the two closed-loop power control indexes based on the specific implementation rule of the application. The specific implementation process includes:

[0331] Step 1: The terminal determines the two closed-loop power control indexes based on a pre-defined rule or signaling indication method.

[0332] Pre-defined rule:

[0333] For example, in the SBFD scenario, if the corresponding uplink transmission is transmitted on the SBFD symbol and / or non-SBFD symbol, the terminal determines the two closed-loop power control indexes (e.g., l=0, 1).

[0334] Signaling indication:

[0335] The terminal determines the two closed loop power control indexes based on the base station signaling indication. Exemplarily, the indication signaling can be SI, RRC, MAC CE, DCI, etc.

[0337] Exemplarily, the power control parameter indication signaling is configured based on MAC CE indication signaling. Exemplarily, the terminal determines the corresponding power control parameter set based on RRC signaling, and determines the power control parameter based on MAC CE. The RRC configured power control parameter set is spatialRelationInfoToAddModList, and the terminal determines the first power control parameter and the second power control parameter in the list based on MAC CE.

[0338] Exemplarily, the power control parameter indication signaling is configured based on DCI indication signaling. Exemplarily, the first closed loop power control index and / or the second closed loop power control index applied are determined based on the DCI-based closed loop indicator, and the corresponding closed loop power parameter is determined based on the DCI-based TPC command and / or second TPC command field.

[0339] Step 2: The terminal determines the time unit corresponding to the closed loop power control index based on the embodiment of the application, and the embodiment includes:

[0340] Sub-embodiment 1:

[0342] l=0 is applied to SBFD time units, and l=1 is applied to non-SBFD time units.

[0343] l=1 is applied to SBFD time units, and l=0 is applied to non-SBFD time units.

[0344] l=0 applies to SBFD time units and non-SBFD time units;

[0345] l=1 applies to SBFD time units and non-SBFD time units.

[0346] Corresponding to different closed loop power control indexes, the terminal determines corresponding closed loop power control parameters based on different closed loop power control indexes respectively.

[0347] Sub-embodiment 2:

[0348] The terminal determines the two closed loop power control indexes based on step 1, and determines the time unit types to which the two closed loop power control indexes apply based on the indication signaling, the indication signaling being used to indicate one or more of the following states:

[0349] l=0 applies to SBFD time units, and l=1 applies to non-SBFD time units;

[0350] l=1 applies to SBFD time units, and l=0 applies to non-SBFD time units;

[0351] l=0 applies to SBFD time units and non-SBFD time units;

[0352] l=1 applies to SBFD time units and non-SBFD time units.

[0353] Corresponding to different closed loop power control indexes, the terminal determines corresponding closed loop power control parameters based on different closed loop power control indexes respectively.

[0354] The signaling includes but is not limited to SI, RRC, MAC CE or DCI.

[0355] Embodiment 2:

[0356] In one possible implementation, the terminal determines one closed loop power control index (e.g., l=0) based on a predefined rule or signaling indication manner, the closed loop power control index being applicable to SBFD and non-SBFD time units simultaneously, and determines corresponding closed loop power control parameters based on time unit types respectively, the specific implementation process including:

[0357] Step 1: The terminal determines the closed loop power control index based on a predefined rule or signaling indication manner;

[0358] Predefined rule:

[0359] Exemplarily, in the SBFD scenario, if the corresponding uplink transmission is transmitted on the SBFD symbol and / or non-SBFD symbol, the terminal determines the corresponding closed-loop power control index, e.g., l=0, e.g., l=1.

[0360] The signaling indication includes:

[0361] The terminal determines the configured closed-loop power control index based on the base station signaling indication. The method is similar to that in Embodiment 1, which will not be described here.

[0362] Step 2: The terminal determines the time unit type to which the closed-loop power control parameter applies based on the scheme of the present application. The specific method includes:

[0363] Corresponding to the closed-loop power control index, it can be applied to the SBFD time unit or the non-SBFD time unit, which is not limited by the present application.

[0364] Corresponding to the closed-loop power control parameter corresponding to the closed-loop power control index, the terminal determines it based on different types of SBFD time units:

[0365] Exemplarily, if the closed-loop power control type is 'absolute', the terminal receives the indication signaling to determine the closed-loop power control parameter indicated by the indication signaling. And based on the time unit type of the uplink transmission indicated by the indication signaling, the terminal determines the time unit type to which the closed-loop common parameter applies.

[0366] Exemplarily, if the closed-loop power control type is 'accumulated', the terminal determines a first time window, which is determined based on the indication signaling or a predefined method. The time window is defined based on the occasion of the uplink transmission. Exemplarily, corresponding to different transmission times, the time window can be the same or different. Corresponding to the uplink transmission located in occasion I, if the occasion i corresponds to the SBFD time unit, the terminal determines the closed-loop power control parameter indicated by all indication signalings applied to the SBFD time unit within the first time window; if the occasion i corresponds to the non-SBFD time unit, the terminal determines the closed-loop power control parameter indicated by all indication signalings applied to the non-SBFD time unit within the first time window.

[0367] Embodiment 3:

[0368] In one possible embodiment, in the SBFD scenario, the terminal determines that the number of corresponding closed-loop power control indexes is 0, i.e., the terminal determines that there is no closed-loop power control index. The terminal determines the corresponding closed-loop power control parameter based on different time unit types.

[0369] The specific manner includes:

[0370] The terminal determines the corresponding closed loop power control parameters based on different types of time units respectively:

[0371] For example, if the closed loop power control type is 'absolute', the terminal receives indication signaling, determines the closed loop power control parameters indicated by the indication signaling, and determines the time unit type to which the closed loop common parameters are applied based on the time unit type in which the uplink transmission is located.

[0372] For example, if the closed loop power control type is 'accumulated', the terminal determines a first time window, which is determined based on indication signaling or a predefined manner, and the time window is defined based on the occasion of the uplink transmission. For example, the time window can be the same or different corresponding to different transmission time points. Corresponding to the uplink transmission located in occasion I, if the occasion i corresponds to an SBFD time unit, the terminal determines the closed loop power control parameters indicated by all indication signaling applied to the SBFD time unit within the first time window; if the occasion i corresponds to a non-SBFD time unit, the terminal determines the closed loop power control parameters indicated by all indication signaling applied to the non-SBFD time unit within the first time window.

[0373] Embodiment 4:

[0374] The main design scheme of the embodiment of the application is to determine the number of closed loop power control parameter indexes corresponding to different types of time units based on a predefined or signaling indication manner:

[0375] Predefined manner:

[0376] The terminal determines the number of closed loop power control parameter indexes corresponding to the SBFD time unit and the non-SBFD time unit based on a predefined rule:

[0377] For example, the uplink transmission is repeated N times (N>1), and the SBFD and non-SBFD time units correspond to two closed loop power control parameter indexes.

[0378] For example, the uplink transmission is repeated once, and the SBFD and non-SBFD time units correspond to one closed loop power control parameter index; or do not correspond to a closed loop power control parameter index.

[0379] Signaling indication:

[0380] The terminal determines the number of closed loop power control parameter indexes corresponding to the SBFD time unit and the non-SBFD time unit based on indication signaling.

[0381] The indication signaling includes but is not limited to SI, RRC, MAC CE and DCI, and the present application does not make any limitation.

[0382] The present application mainly designs the application scheme in the SBFD scenario, determines the closed-loop power control parameter index corresponding to different types of time units, i.e., SBFD time unit and non-SBFD time unit.

[0383] In one possible implementation, the network side selects to send SIB1 on demand based on access users, service requirements, etc. The scenario mainly corresponds to users in the Idle state / Inactive state. As shown in FIG. 4-3, during the on-demand SIB1 at the network side and without sending the corresponding SIB1, the terminal can trigger the transmission of the corresponding SIB1 based on the corresponding WUS signal. If the terminal sends the corresponding WUS signal, it needs to obtain the corresponding WUS configuration. In the scenario, the terminal can obtain the corresponding WUS configuration based on the cell A (e.g., anchor cell) and send the WUS on the cell A or NES (network energy saving) cell (e.g., non-anchor cell) based on the configuration.

[0384] Based on the scenario, the corresponding cell A / NES cell can be defined based on the following ways:

[0385] Cell A: The cell in which the base station normally sends SIB1 based on semi-static configuration. For example, the cell can be the cell that sends the WUS configuration of other cells. For example, the cell can be an anchor cell.

[0386] NES: The SIB1 corresponding to the NES cell is sent based on the on-demand mode. It is worth noting that the SIB1 corresponding to the NES cell can be sent in the on-demand mode in the NES cell itself or in other cells, for example, the cell A, and the present application does not make any limitation.

[0387] In one possible implementation, in the scenario in which the cell is an NES cell, the k SSB satisfies the following condition: k SSB >23 for FR1 or k SSB >11 for FR2. For example, the k SSB based on signaling indication, for example, based on MIB and / or PBCH load indication. For example, the k SSB based on ssb-SubcarrierOffset indication; in one possible implementation, in the scenario in which the cell is an NES cell, the kSSB satisfies the following condition: k SSB ≤ 23 for FR1 or if k SSB ≤ 11 for FR2. Wherein, the k SSB Based on signaling indication, for example, based on MIB and / or PBCH load indication, exemplary, the k SSB Based on ssb-SubcarrierOffset indication;

[0388] A possible implementation, corresponding to the frequency domain offset between SSB and resource block RB (for example, common resource block CRB) on the NES cell can be indicated based on WUS (wake up signaling) configuration or other indication signaling, exemplary, the WUS configuration or other indication signaling can be based on cell A transmission, or based on NES cell transmission, the present application does not limit this;

[0389] A possible implementation, corresponding to the configuration information of Type0-PDCCH CSS set and corresponding CORESET on the NES cell can be indicated based on WUS (wake up signaling) configuration or other indication signaling, exemplary, the WUS configuration or other indication signaling can be based on cell A transmission, or based on NES cell transmission, the present application does not limit this.
