[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 uplink subbands, the network device can receive information sent by the terminal in the uplink subband of the SBFD time unit, and can 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 uplink subbands in the frequency domain resources corresponding to slot#n+1 to slot#n+3. In the case where the 3 flexible slots of slot#n+1 to slot#n+3 are used for downlink transmission, the network device can perform uplink transmission in the uplink subbands corresponding to the 3 slots, and can perform downlink transmission in the frequency domain resources (for example, referred to as downlink subbands) outside the uplink subbands corresponding to the 3 slots, so that full duplex communication can be realized in the 3 slots configured with uplink subbands.

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

[0112] It should be noted that, in the time domain unit configured with the subband, although the network device can realize full duplex communication, in some embodiments, the terminal can still only perform half duplex communication, that is, can only perform uplink communication or downlink communication in a single time domain unit; or, in some embodiments, the terminal can also perform full duplex communication, that is, can perform uplink communication and downlink communication in a single time domain unit.

[0113] In some embodiments, during 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 on the non-SBFD time unit, and in this case, the transmission needs to be based on the transmission 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, the transmission environment, the interference condition, etc. configured by the network device are different, and the corresponding transmission parameter needs to be based on the corresponding transmission 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 subband is the SBFD time unit, and the time unit not configured with the subband is the non-SBFD time unit (that is, the traditional time unit).

[0118] In some embodiments, the terminal can determine at least one transmission parameter set corresponding to the SBFD time unit and the non-SBFD time unit, and the at least one transmission parameter set can be one transmission parameter set or multiple transmission parameter sets, such as 2 transmission parameter sets or more.

[0119] For example, one transmission parameter set can include one or more transmission parameters, and the specific transmission parameters included are described in subsequent embodiments. For example, the types of transmission parameters included in each transmission parameter set can be the same or different, and the present disclosure does not limit this.

[0120] It should be noted that the at least one set of transmission parameters determined by the terminal can be determined based on a predefined rule (for example, a protocol agreement) or based on network device indication, and the present disclosure does not limit this.

[0121] In step S201, according to the predefined rule or the indication information, the transmission parameters corresponding to the transmission between the terminal and the network device in the SBFD time unit and the non-SBFD time unit are determined from the at least one set of transmission parameters.

[0122] In step S202, the terminal can use the corresponding transmission parameters for transmission in the SBFD time unit and the non-SBFD time unit.

[0123] In some embodiments, for transmission in the SBFD time unit and the non-SBFD time unit, due to different configurations of antennas, transmission environments, interference conditions, etc., the transmission parameters corresponding to the transmission in the SBFD time unit and the non-SBFD time unit, such as power control parameters and / or spatial relationship parameters, can be different.

[0124] Taking the power control parameter as an example, to realize separate power control configuration in the SBFD time unit and / or the non-SBFD time unit, one possible implementation is to configure different resource parameters based on the SBFD time unit and the non-SBFD time unit, for example, to configure different resource sets respectively. Based on this, different configuration resources corresponding to the SBFD time unit and the non-SBFD time unit can be realized. Considering that in the related mechanism, the corresponding power control parameters are configured based on specific resources and / or resource sets to which the resources belong, based on the above configuration, separate power control in the SBFD time unit and the non-SBFD time unit can be realized. However, the above method increases the configuration overhead of the resource set at the cost of the SRS resource set. For example, in the related mechanism, for the sTRP scenario, the number of configurable SRS resource sets is usually 1 for the usage of codebook or non-codebook. If 2 SRS resource sets are configured, it can correspond to the mTRP scenario, or not correspond to the mTRP scenario, and the present disclosure does not limit this.

[0125] For a specific BWP, the maximum number of configurable SRS resource sets is 16. Based on the SBFD time unit and the non-SBFD time unit, different SRS resource sets are configured, and on the basis of ensuring existing performance, the required set overhead may be doubled.

[0126] According to an embodiment of the present disclosure, for transmission between the network device and the terminal, corresponding transmission 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 transmission parameters of the resource on the SBFD time unit, and perform transmission on the non-SBFD time unit based on the corresponding transmission parameters 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.

[0127] In some embodiments, the terminal can determine the time unit in which the transmission is located.

[0128] 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.

[0129] For example, the corresponding transmission parameters of the transmission on the SBFD time unit are denoted as a first set of transmission parameters (which can include one or more transmission parameters), and the corresponding transmission parameters of the transmission on the non-SBFD time unit are denoted as a second set of transmission parameters (which can include one or more transmission parameters).

[0130] In the case of transmission on the SBFD time unit, the terminal can perform transmission based on the transmission parameters in the first set of transmission parameters;

[0131] In the case of transmission on the non-SBFD time unit, the terminal can perform transmission based on the transmission parameters in the second set of transmission parameters.

[0132] 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 indirectly determine the time unit in which the transmission is located according to scheduling information used to schedule the transmission, for example, 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, 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.

[0133] In some embodiments, the set of transmission parameters can be configured by the network device. The network device can configure the set of transmission parameters for the terminal through system information, RRC (Radio Resource Control) signaling, MAC CE (Media Access Control Control Element), DCI (Downlink Control Information), etc.

[0134] Further, for example, the network device can indicate the set of transmission parameters through an IE (Information Element) or field in the signaling.

[0135] It should be noted that the signaling for indicating the set of transmission parameters 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.

[0136] Taking at least one transmission set including two sets of transmission parameters as an example, and taking the transmission parameter set configured through RRC signaling or system information as an example, the two sets of transmission parameters indicated by the network device can be different based on the specific parameter type, for example, can include:

[0137] SRI-PUSCH-MappingToAddModList and SRI-PUSCH-MappingToAddModList2, SRI stands for SRS resource indication (SRS resource indication), the transmission parameters in the two sets of transmission parameters 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;

[0138] p0-PUSCH-Alpha and p0-PUSCH-Alpha2, the transmission parameters in the two sets of transmission parameters include a target received power and a path loss adjustment coefficient;

[0139] pathlossReferenceIndex and pathlossReferenceIndex2, the transmission parameters in the two sets of transmission parameters are path loss reference signal resource indexes;

[0140] powerControlLoopToUse and powerControlLoopToUse2, the transmission parameters in the two sets of transmission parameters are power control parameter indexes;

[0141] spatialRelationInfoToAddModList and spatialRelationInfoToAddModList2, the transmission parameters in the two sets of transmission parameters are spatial relations and / or power control relations.

[0142] Take the configuration of transmission parameter set by RRC signaling and MAC CE as an example. RRC signaling can be used to indicate the transmission parameter set, such as spatialRelationInfoToAddModList and spatialRelationInfoToAddModList2. MAC CE can be used to indicate the 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.

[0143] Take the configuration of power control parameter by RRC signaling and DCI as an example. RRC signaling can be used to indicate the power control parameter, such as SRI-PUSCH-MappingToAddModList and SRI-PUSCH-MappingToAddModList2. DCI can be used to indicate the specific application of the power control parameter 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.

[0144] Take the indication of power control parameter 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, such as determining the closed loop power control index l corresponding to the transmission on the non-SBFD time unit based on powerControlLoopToUse2.

[0145] Taking the transmission parameter indicated by the DCI as an example. For example, the transmission 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 a closed loop indicator. For example, the transmission parameter includes a parameter δ. The DCI can indicate the corresponding first closed loop power control parameter of the transmission on the SBFD time unit and the corresponding second closed loop power control parameter of the transmission on the non-SBFD time unit through a TPC (Transmit power control) information field.

[0146] In some embodiments, the at least one transmission parameter set includes a first transmission parameter set and a second transmission parameter set, and the predefined rule includes at least one of the following:

[0147] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit, and the second transmission parameter set is a transmission parameter set corresponding to the transmission on the non-SBFD time unit.

[0148] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the non-SBFD time unit, and the second transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit.

[0149] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit and the non-SBFD time unit.

[0150] The second transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit and the non-SBFD time unit.

[0151] In some embodiments, the at least one transmission parameter set includes a first transmission parameter set and a second transmission parameter set, and the indication information (such as RRC signaling, MAC CE, DCI, etc.) is used to indicate at least one of the following:

[0152] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit, and the second transmission parameter set is a transmission parameter set corresponding to the transmission on the non-SBFD time unit.

[0153] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the non-SBFD time unit, and the second transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit.

[0154] The first transmission parameter set is a transmission parameter set corresponding to the transmission on the SBFD time unit and the non-SBFD time unit.

[0155] The second set of transmission parameters is a set of transmission parameters corresponding to the SBFD time unit and the non-SBFD time unit.

[0156] For example, the indication information is DCI, and the DCI indicates the transmission parameters through the TPC command field.

[0157] For example, the terminal can determine the first transmission parameter based on the TPC command field #1 in the DCI and determine the second transmission parameter based on the TPC command field #2 in the DCI.

[0158] Further, the terminal determines the time unit type corresponding to the first transmission parameter and the second transmission parameter according to a predefined rule or indication information, for example, the first transmission parameter is applied to the SBFD time unit, and the second transmission parameter is applied to the non-SBFD time unit.

[0159] Further, taking transmission of PUSCH as an example, the terminal can determine the time unit in which the PUSCH is located based on the indication of the network device (for example, based on the indication of the DCI). For example, the PUSCH is transmitted in the SBFD time unit, and the terminal determines that the PUSCH is transmitted based on the first transmission parameter; the PUSCH is transmitted in the non-SBFD time unit, and the terminal determines that the PUSCH is transmitted based on the second transmission parameter.

[0160] The above several embodiments mainly illustrate the technical solutions of the present disclosure in the case where the at least one set of transmission parameters includes two sets of transmission parameters. The following several embodiments illustrate the case where the at least one set of transmission parameters includes one set of transmission parameters.

[0161] In some embodiments, taking the case where the set of transmission parameters is configured through RRC signaling or system information as an example, the set of transmission parameters indicated by the network device can be different based on the specific parameter type, for example, can include:

[0162] SRI-PUSCH-MappingToAddModList, the transmission parameter in the set of transmission parameters can be one or more, including but not limited to a path loss reference signal, a path loss adjustment coefficient, a closed loop power control parameter index, and a target received power;

[0163] p0-PUSCH-Alpha, the transmission parameter in the set of transmission parameters includes a target received power of the terminal, a path loss adjustment coefficient, etc.

[0164] pathlossReferenceIndex, the transmission parameter in the set of transmission parameters is a path loss reference signal resource index;

[0165] powerControlLoopToUse, the transmission parameter in the transmission parameter set is a closed loop power control parameter index;

[0166] spatialRelationInfoToAddModList, the transmission parameter in the transmission parameter set is a spatial relation.

[0167] Take the transmission parameter set configured by RRC signaling and MAC CE as an example. RRC signaling can be used to indicate the transmission parameter set, such as spatialRelationInfoToAddModList. MAC CE can be used to indicate the transmission parameter in spatialRelationInfoToAddModList.

[0168] Take the power control parameter configured by RRC signaling and DCI as an example. RRC signaling can be used to indicate the power control parameter, such as SRI-PUSCH-MappingToAddModList. DCI can be used to indicate the power control parameter in SRI-PUSCH-MappingToAddModList.

[0169] Take the power control parameter indicated by RRC signaling as an example, such as powerControlLoopToUse. The terminal can determine the closed loop power control index l according to it.

[0170] Take the transmission parameter indicated by DCI as an example. For example, the transmission parameter includes a closed loop power control index, and the DCI can indicate the closed loop power control index by a closed loop indicator. For example, the transmission parameter includes a closed loop power control parameter, and the DCI can indicate the closed loop power control parameter by a TPC information field.

[0171] The above several examples describe the case where the indication signaling indicates one power control parameter set, and the correspondence between the SBFD time unit and the non-SBFD time unit for this one power control parameter set is described in subsequent embodiments.

[0172] In some embodiments, at least one transmission parameter set includes one transmission parameter set, wherein at least one of the following is included according to a predefined rule:

[0173] determine the signaling for indicating the transmission parameter set;

[0174] determine the type of the time unit where the signaling schedules the transmission, the type including an SBFD time unit and / or a non-SBFD time unit;

[0175] determine that the transmission parameter set is the transmission parameter set corresponding to the type of time unit

[0176] The signaling for indicating the set of transmission parameters includes DCI, for example, the DCI can indicate the set of transmission parameters by reserving bits, a TPC information field, etc., so that the DCI can indicate the set of transmission parameters and also schedule the transmission. The terminal determines the type of time unit in which the transmission scheduled by the DCI is located, for example, the transmission scheduled by the DCI includes PUSCH.

[0177] When the PUSCH scheduled by the DCI is on the SBFD time unit, the terminal can determine that the set of transmission parameters corresponds to the SBFD time unit, so that the PUSCH can be transmitted on the SBFD time unit based on the set of transmission parameters indicated by the DCI.

[0178] When the PUSCH scheduled by the DCI is on the non-SBFD time unit, the terminal can determine that the set of transmission parameters corresponds to the non-SBFD time unit, so that the PUSCH can be transmitted on the non-SBFD time unit based on the set of transmission parameters indicated by the DCI.

[0179] It should be noted that the PUSCH scheduled by the DCI can be on the SBFD time unit, or can be on the non-SBFD time unit, or can be on both the SBFD time unit and the non-SBFD time unit.

[0180] In some embodiments, the terminal can receive signaling for indicating at least one set of transmission parameters, wherein one first information field in the signaling is used to indicate one set of transmission parameters.

[0181] For example, the network device can indicate at least one set of transmission parameters through signaling, for example, the signaling includes DCI, the DCI can indicate one set of transmission parameters through one first information field therein, and when multiple sets of transmission parameters need to be indicated, multiple first information fields need to be used for indication. For example, the number of first information fields in the DCI is equal to the number of sets of transmission parameters. 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, but can also be other information fields, and the present disclosure will not be described here.

[0182] It should be noted that the signaling for indicating the set of transmission parameters is not limited to DCI, but can also be indicated by system information, RRC signaling, MAC CE, etc. For example, in the case of indicating the set of transmission parameters by RRC signaling, the RRC signaling can be indicated by an information unit (Information Element, IE).

[0183] 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:

[0184] The transmission comprises multiple transmissions, and the number of the first information fields in the signaling is multiple;

[0185] The transmission comprises one transmission, and the number of the first information fields in the signaling is one.

[0186] Since the number of the transmission parameter sets can be one or multiple, and with the number of the transmission parameter sets being different, the number of the first information fields is also different, and the number of the first information fields being different leads to the size (i.e., the number of bits) of the signaling where the first information is located being different.

[0187] In this embodiment, the terminal determines, based on a predefined rule, that the number of the first information fields in the signaling is multiple in the case where the transmission comprises multiple transmissions, for example, in the case where the transmission is repetition. Since the transmission comprises multiple transmissions, there are different transmissions in different types of time units, and it is necessary to indicate that multiple transmission parameter sets correspond to different types of time units through multiple first information fields.

[0188] And in the case where the transmission comprises one transmission, the number of the first information fields in the signaling is determined to be one. Since the transmission comprises one transmission, there is generally no transmission in different types of time units, and therefore one transmission parameter set can be indicated to correspond to one type of time unit through one first information field.

[0189] For example, taking the case where the transmission comprises PUSCH, the signaling comprises DCI, and the first information field comprises a TPC information field as an example. In the case where the PUSCH is repetition transmission, the terminal can determine that the DCI contains multiple TPC information fields; in the case where the PUSCH is single 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 then accurately determine the size of the DCI, so as to accurately parse the DCI based on the size.

[0190] The above embodiments mainly take the transmission as uplink transmission, and take PUSCH as an example to illustrate the technical solutions of the disclosure. The transmission in the embodiments of the disclosure is not limited to PUSCH, and the transmission is exemplarily illustrated through several embodiments as follows.

[0191] In some embodiments, the terminal can determine the time domain position of the SBFD time unit based on the network device configuration and the corresponding rule. In the case where the terminal transmits data on the SBFD time unit based on scheduling, the terminal determines that the data transmission corresponds to the SBFD time unit.

[0192] Taking transmission of PUSCH including DCI scheduling as an example, if the terminal determines, based on the DCI scheduling information, that the PUSCH is transmitted on occasion i.

[0193] If the terminal determines, based on the network device configuration and the corresponding rule, that occasion i corresponds to an SBFD time unit, the terminal determines that the PUSCH is transmitted on the SBFD time unit. For example, transmission in the UL subband frequency domain range corresponding to occasion i.

[0194] If the terminal determines, based on the network device configuration or the corresponding predefined rule, that occasion i is non-SBFD, the terminal determines that the PUSCH is transmitted on the non-SBFD time unit. For example, transmission in the UL BWP frequency domain range corresponding to occasion i.

[0195] Corresponding to the uplink data transmitted on occasion i, if occasion i contains both SBFD time units and non-SBFD time units, the terminal determines the type of time unit corresponding to occasion i based on at least one of the following manners:

[0196] The terminal determines that occasion i corresponds to an SBFD time unit, or the terminal determines that occasion i corresponds to a non-SBFD time unit.

[0197] The terminal determines the type of time unit corresponding to occasion i based on the first time unit corresponding to occasion i. For example, if the first time unit is an SBFD time unit, the terminal determines that the type of time unit corresponding to occasion i is SBFD; if the first time unit is a non-SBFD time unit, the terminal determines that the type of time unit corresponding to occasion i is non-SBFD.

[0198] The terminal determines that occasion i corresponds to both an SBFD time unit and a non-SBFD time unit.

[0199] If 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, a traditional mechanism is used to determine the corresponding power control parameters.

[0200] In some embodiments, a transmission occasion i can be defined by an index of a slot within a System Frame Number (SFN) corresponding frame, e.g., a starting symbol S of an uplink transmission in the slot, and a duration L of the transmission symbol. For PUSCH repetition transmission of Type B, one PUSCH transmission occasion is a nominal repetition transmission, e.g., refer to 3GPP protocol [6, TS 38.214].

[0201] In some embodiments, the transmission comprises at least one of: an uplink transmission; a downlink transmission.

[0202] In some embodiments, the uplink transmission comprises at least one of:

[0203] a physical uplink control channel (PUCCH);

[0204] a physical uplink shared channel (PUSCH);

[0205] a sounding reference signal (SRS).

[0206] In some embodiments, the downlink transmission comprises at least one of:

[0207] a physical downlink control channel (PDCCH);

[0208] a physical downlink shared channel (PDSCH);

[0209] a channel state information reference signal (CSI-RS);

[0210] a synchronization signal block (SSB).

[0211] The following illustrates the transmission in the set of transmission parameters by several embodiments.

[0212] In some embodiments, the type of the parameter in the set of transmission parameters comprises at least one of:

[0213] a power control parameter;

[0214] a spatial relation parameter.

[0215] In some embodiments, the spatial relation parameter comprises at least one of:

[0216] a cell to which the spatial relation applies;

[0217] a bandwidth part (BWP) to which the spatial relation applies;

[0218] a resource to which the spatial relation applies;

[0219] a spatial relation reference signal;

[0220] a quasi co-located (QCL) type.

[0221] Exemplarily, the spatial relation reference signal comprises at least one of: SRS, CSI-RS, SSB.

[0222] In some embodiments, the power control parameter comprises at least one of:

[0223] a target received power, e.g., P0;

[0224] a path loss reference signal, or a path loss reference signal resource index, e.g., q d ;

[0225] a path loss adjustment state, e.g., alpha;

[0226] a closed loop power control index l, also referred to as a data power control adjustment state index, e.g., the value can be 1 or 0, the data can comprise PUSCH, PUCCH, SRS, etc. transmission;

[0227] a closed loop power control parameter f b,f,c (i, l), e.g., for uplink transmission PUSCH, in case of accumulated closed loop power control type, or, in 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.

[0228] In some embodiments, taking SRS as an example, the transmission comprises uplink transmission.

[0229] For example, alpha and P0 can be determined based on SRS Resource set.

[0230] For example, qd The configuration can be based on RRC signaling or based on MAC CE indication.

[0231] 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, then 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 the PUSCH scheduled by the RAR UL grant, then l = 0. Wherein, RAR represents Random Access Response (Random Access Response).

[0232] For example, δPUSCH,b,f,c(m,l) represents the 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 indicates one of the indexes in Table 1 below, and the terminal determines the value of δPUSCH,b,f,c(m,l) corresponding to the index based on the closed loop power control type, e.g., accumulation or absolute.

[0233] Table 1

[0234] For example, the accumulated value can be the accumulated δPUSCH,b,f,c(m,l) in dB, and the absolute value can be the absolute δPUSCH,b,f,c(m,l) in dB.

[0235] For example, δPUSCH,b,f,c(m,l) can be used to calculate the accumulated value

[0236] The sum of the accumulated powers of δPUSCH,b,f,c(m,l) corresponding to the m TPC command indications of index l in a period of time (e.g., t1 to t2). Wherein:

[0237] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission time i-i0, N = K PUSCH (i-i0)-1.

[0238] t2 = the time corresponding to the M OFDM symbols before the PUSCH transmission time i, M = K PUSCH (i).

[0239] Wherein, i0>0 is the symbol K PUSCH (i-i0) is earlier than the K PUSCH(i) the minimum integer of the symbol condition.

[0240] 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.

[0241] For CG (Configured Grant) PUSCH, K PUSCH (i) corresponds to the number of symbols in each slot and the minimum value determined by the parameter k2 (which can be referred to in the relevant documents, and the present disclosure will not be described here) The product of the parameters. For example, the k2 can be determined based on signaling indication, for example, based on PUSCH power control configuration (PUSCH-ConfigCommon) indication.

[0242] Wherein, if the first symbol of the PUSCH transmission occasion occurs after the last symbol of the PDCCH reception T (proc,2) corresponding to the time range, the UE can delay to meet the T (proc,2) limitation (T (proc,2) determined outside the time range) and then apply the TPC command.

[0293] The technical solutions of the present disclosure are exemplarily described below through several embodiments.

[0294] 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 the 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.

[0295] In some embodiments, the terminal supporting the SBFD feature can be configured by the base station to receive downlink data on a DL subband on an UL or flexible symbol, and / or transmit uplink data on an UL subband.

[0296] As described above, the terminal can determine the time domain location of the SBFD time unit based on the base station configuration and the corresponding rules. If 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. Taking the PUSCH scheduled by the DCI as an example, if the terminal determines that the PUSCH is transmitted on occasion i based on the DCI scheduling information. Correspondingly, if the terminal determines that the occasion i corresponds to the SBFD time unit based on the base station configuration and the corresponding rules, the terminal determines that the PUSCH is transmitted on the SBFD time unit. For example, the occasion i corresponds to the transmission in the UL subband frequency domain range. On the contrary, if the terminal determines that the time unit is non-SBFD based on the base station configuration or the corresponding predefined rules, the terminal determines that the PUSCH is transmitted on the non-SBFD time unit. For example, the occasion i corresponds to the transmission in the UL BWP frequency domain range.

[0297] As described above, the design scheme of the embodiments of the present disclosure determines the transmission parameters of the corresponding data transmission on the SBFD time unit and the non-SBFD time unit based on the transmission parameter indication signaling in the SBFD scenario. The transmission parameter indication signaling includes one or more of the following: RRC, MAC CE, DCI.

[0298] The data transmission includes but is not limited to at least one of the following:

[0299] The uplink transmission includes but is not limited to PUSCH, SRS, PUCCH, etc.

[0300] The downlink transmission includes but is not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0301] The transmission parameters include but are not limited to at least one of the following:

[0302] The power control related parameters;

[0303] The spatial relationship related parameters and / or the beam related parameters.

[0304] In the following, the embodiments of the present disclosure take the uplink transmission as an example to describe the specific rules of the present application, but the above-mentioned scheme can also be applied to the downlink transmission, and the present application does not limit this.

[0305] As described above, for the transmission on the SBFD time unit and the non-SBFD time unit, due to the difference in the configured antenna, the transmission environment, the interference condition, etc., the power control parameters and / or the spatial relation parameters on the corresponding SBFD time unit and the non-SBFD time unit can be different. Taking the power control parameters as an example, in order to realize the separate power control configuration on the SBFD time unit and / or the non-SBFD time unit, the power control parameters of the uplink transmission on the SBFD time unit and the non-SBFD time unit can be respectively indicated based on different power control parameter indication signaling. The power control parameters of the uplink transmission on the SBFD time unit and the non-SBFD time unit can also be respectively indicated based on the same power control parameter indication signaling.

[0306] Based on the above analysis, the embodiments of the present disclosure mainly consider that based on different transmission parameter indication signaling configuration conditions, corresponding invention schemes are designed to determine the transmission parameters of the corresponding data transmission of the terminal on the SBFD time unit and / or the non-SBFD time unit.

[0307] If the transmission parameter corresponds to the power control parameter, the parameter includes but is not limited to: target received power P0; path loss reference signal q d ; path loss adjustment coefficient alpha; closed loop power control index l; closed loop power control parameter.

[0308] If the transmission parameter corresponds to the power control parameter set, the parameter set consists of one or more of the parameters. The parameter set contains the power control parameters corresponding to one or more resources in the set.

[0309] If the transmission parameter corresponds to the spatial relation related parameter, the parameter includes but is not limited to: corresponding spatial relation parameter application cell; corresponding spatial relation parameter application BWP; spatial relation reference signal; SRS resource; QCL type.

[0310] If the transmission parameter corresponds to the spatial relation parameter set, the parameter set consists of one or more of the parameters.

[0311] The parameter set contains the spatial relation parameters corresponding to one or more resources in the set.

[0312] In the following, the present application takes the data transmission as the uplink transmission and the transmission parameter as the power control parameter as an example to describe the specific scheme of the present application, which is used for the terminal to determine the related transmission parameters of the corresponding data transmission on the SBFD time unit and / or the non-SBFD time unit. It is worth noting that the corresponding data transmission can also be the downlink transmission, and the transmission parameter can also be the power control parameter, the spatial relation parameter set, the spatial relation parameter, etc., and the present application does not limit this.

[0313] Embodiment 1:

[0314] In one possible implementation, the terminal determines the first and second power control parameters based on the first and second power control parameter indication signaling respectively, and determines the power control parameters for the corresponding uplink transmission in the SBFD time unit and non-SBFD time unit based on a predefined rule or indication signaling, under the condition that the terminal is configured with the first and second power control parameter indication signaling.

[0315] For example, the power control parameter indication signaling can be existing power control related indication signaling or SBFD specific power control parameter related indication signaling, and the present application does not limit this.

[0316] For example, the power control parameter indication signaling is configured based on RRC signaling or system signaling, and the power control parameter indication signaling includes but is not limited to: SRI-PUSCH-MappingToAddModList, SRI-PUSCH-MappingToAddModList2, p0-PUSCH-Alpha, p0-PUSCH-Alpha2, pathlossReferenceIndex, pathlossReferenceIndex2, powerControlLoopToUse, powerControlLoopToUse2.

[0317] For example, the power control parameter indication signaling is configured based on MAC CE indication signaling, and for example, 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 and second power control parameters in the list based on MAC CE.

[0318] For example, the power control parameter indication signaling is indicated based on DCI indication signaling, and for example, the first and / or second closed loop power control index applied is determined based on the closed loop indicator of DCI, and for example, the corresponding closed loop power parameter is determined based on the TPC command and / or second TPC command field of DCI.

[0319] Sub-embodiment 1:

[0320] The terminal determines the first and second power control parameter indication signaling based on the base station configuration, and determines the time unit type to which the corresponding power control parameters indicated by the first and second power control parameter indication signaling are applied based on a predefined rule, which includes one or more of the following:

[0321] The first power control parameter corresponds to uplink transmission in SBFD time units, and the second power control parameter corresponds to uplink transmission in non-SBFD time units.

[0322] The second power control parameter corresponds to uplink transmission in non-SBFD time units, and the first power control parameter corresponds to uplink transmission in SBFD time units.

[0323] The first power control parameter corresponds to uplink transmission in SBFD time units and non-SBFD time units.

[0324] The second power control parameter corresponds to uplink transmission in SBFD time units and non-SBFD time units.

[0325] Sub-embodiment 2:

[0326] The terminal determines the first and second power control parameter indication signaling based on the base station configuration, and determines the time unit type to which the corresponding power control parameters indicated by the first and second power control parameter indication signaling are applied based on the indication signaling, which includes but is not limited to RRC, MAC CE and DCI indication signaling. The signaling indication state includes but is not limited to one or more of the following:

[0327] The first power control parameter corresponds to uplink transmission in SBFD time units, and the second power control parameter corresponds to uplink transmission in non-SBFD time units.

[0328] The second power control parameter corresponds to uplink transmission in non-SBFD time units, and the first power control parameter corresponds to uplink transmission in SBFD time units.

[0329] The first power control parameter corresponds to uplink transmission in SBFD time units and non-SBFD time units.

[0330] The second power control parameter corresponds to uplink transmission in SBFD time units and non-SBFD time units.

[0331] Based on any of the above manners, the terminal determines the corresponding power control parameter applied to the current data transmission based on the time unit type to which the corresponding power control parameter indicated by the first power control parameter indication signaling and the second power control parameter indication signaling applies.

[0332] As described above, the terminal determines the time unit type in which the current data transmission is located based on the base station configuration or the corresponding predefined rule. And determines the time unit type in which the data transmission is located based on the corresponding relationship between the power control parameter and the time unit type.

[0333] Taking the TPC command field and the second TPC command field of the DCI as an example, the terminal determines the power control parameter applied to the uplink transmission (e.g., PUSCH) scheduled by the DCI based on the following implementation process.

[0334] Step 1: The terminal determines the first power control parameter and the second power control parameter indicated by the two TPC command fields based on the above indication signaling.

[0335] Step 2: The terminal determines the time unit type to which the first power control parameter and the second power control parameter correspond based on any of the above methods. For example, the first power control parameter applies to the SBFD time unit, and the second power control parameter applies to the non-SBFD time unit.

[0336] Step 3: The terminal determines the time unit applied to the PUSCH transmission based on the indication information of the DCI indication signaling. For example, if the corresponding PUSCH is transmitted in the SBFD time unit, the terminal determines that the PUSCH is transmitted based on the first power control parameter; if the corresponding PUSCH is transmitted in the non-SBFD time unit, the terminal determines that the PUSCH is transmitted based on the second power control parameter.

[0337] Embodiment 2:

[0338] In one possible implementation, under the condition that the terminal is configured with the first power control parameter indication signaling, the terminal determines the first power control parameter based on the first power control parameter indication signaling, and determines the time unit type to which the first power control parameter applies based on the predefined rule or the indication signaling.

[0339] For example, the power control parameter indication signaling can be an existing power control related indication signaling, or an SBFD specific power control parameter related indication signaling, which is not limited by the present application.

[0340] Exemplarily, the power control parameter indication signaling is based on RRC signaling or system information configuration, and the power control parameter indication signaling includes but is not limited to: SRI-PUSCH-MappingToAddModList, p0-PUSCH-Alpha, pathlossReferenceIndex, powerControlLoopToUse, p0-nominal, deltaPreamble, etc.

[0341] Exemplarily, the power control parameter indication signaling is based on MAC CE indication signaling configuration, and exemplarily, the terminal determines a corresponding power control parameter set based on RRC signaling and determines the power control parameter based on the MAC CE. The RRC configured power control parameter set is spatialRelationInfoToAddModList, and the terminal determines the first power control parameter in the list based on the MAC CE.

[0342] Exemplarily, the power control parameter indication signaling is based on DCI indication signaling indication, and exemplarily, the first closed loop power control index applied is determined based on the DCI-based closed loop indicator, and exemplarily, the corresponding closed loop power parameter is determined based on the DCI-based TPC command field.

[0343] Exemplarily, the terminal determines the time unit type to which the first power control parameter is applied based on a predefined manner, and further determines the power control parameter corresponding to the uplink data transmitted on the corresponding time unit type.

[0344] The predefined rule includes that the terminal determines the corresponding time unit type based on the resource type on which the uplink transmission corresponding to the first power control parameter is located, and further determines the time unit type to which the first power control parameter is applied.

[0345] Taking the TPC command field of the DCI as an example, if the uplink transmission data (e.g., PUSCH) scheduled by the DCI is located on an SBFD time unit, the terminal determines that the power control parameter indicated by the TPC command field is applied to the SBFD time unit.

[0346] Exemplarily, the terminal determines the time unit type to which the first power control parameter is applied based on the indication signaling, and further determines the power control parameter corresponding to the uplink data transmitted on the corresponding time unit type.

[0347] The indication signaling includes but is not limited to: system information (SI), RRC, MAC CE, DCI.

[0348] The first power control parameter indication signaling is a TPC command field of DCI, the first power control parameter corresponds to a time unit, and the indication signaling is DCI. The terminal determines that the power control parameter indicated by the TPC command field is applied to the SBFD time unit based on a specific information field of the DCI. The specific information field of the DCI can be a reserved bit of an existing DCI, a reserved information field, and the like, which is not limited in the present application.

[0353] For example, the terminal determines the number of configured power control parameter indication signals based on a predefined rule. For example, the terminal determines the number of configured power control parameter indication signals based on the number of uplink transmission repetitions. For example, if the uplink transmission is repeated N times (N>1), the terminal determines to configure two power control parameter indication signals; if the uplink transmission is repeated once, the terminal determines to configure one power control parameter indication signal.

[0354] For example, the terminal determines the number of configured power control parameter indication signals based on a predefined rule. For example, the terminal determines the number of configured power control parameter indication signals based on the number of uplink transmission repetitions. For example, if the uplink transmission is repeated N times (N>1), the terminal determines to configure two power control parameter indication signals; if the uplink transmission is repeated once, the terminal determines to configure one power control parameter indication signal.
