[0110] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU, but is not limited thereto.

The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is exemplary, each subject can not be connected or can be connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0113] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0114] 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.

[0115] 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.

[0116] For example, the time unit can include at least one of a frame, a subframe, a slot, a symbol, and a sub-slot. The symbol can be, for example, an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0117] For example, for the SBFD time unit configured with the uplink subband, 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.

[0118] FIG. 1B is a schematic diagram of a subband according to an embodiment of the present disclosure.

[0119] 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.

[0120] 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 where 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 can 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.

[0121] 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.

[0122] 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.

[0123] 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 power control parameter.

[0124] 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.

[0125] And determining the power control parameter for the SBFB time unit and the non-SBFD time unit respectively, at least two sets of power control parameters need to be determined, each set of power control parameters contains one or more power control parameters, for example, it can be a power control parameter set, one set of power control parameters is used for transmission on the SBFD time unit, and another set of power control parameters is used for transmission on the non-SBFD time unit. This will bring relatively large overhead for the terminal and the network device.

[0126] For convenience of description, the two sets of power control parameters are denoted as the first power control parameter and the second power control parameter.

[0127] FIG. 2A is an interaction schematic diagram of a parameter determination method according to an embodiment of the present disclosure.

[0128] In step S201, the terminal receives the first indication information sent by the network device.

[0129] In some embodiments, the network device sends the first indication information to the terminal.

[0130] In some embodiments, the terminal determines the first power control parameter according to the first indication information.

[0131] In step S202, the terminal determines the power control offset parameter based on the first predefined rule or the second indication information.

[0132] In some embodiments, the first TCI parameter and the TCI offset parameter are used to determine the second TCI parameter.

[0133] For example, the second TCI parameter is equal to the first TCI parameter plus the TCI offset parameter, or the second TCI parameter is equal to the first TCI parameter minus the TCI offset parameter.

[0134] It should be noted that, in order to determine the second TCI parameter, the operation relationship between the first TCI parameter and the TCI offset parameter is not limited to the above addition and subtraction, and the second TCI parameter can also be determined by other operation relationships, and the present disclosure does not limit this.

[0135] According to embodiments of the present disclosure, the network device only needs to indicate the first TCI parameter to the terminal through the first indication information, and does not need to directly indicate the second TCI parameter, the terminal can determine the TCI offset parameter based on the first predefined rule, and then determine the second TCI parameter based on the first TCI parameter and the TCI offset parameter, accordingly, it is beneficial to save the signaling overhead of the network device; or the terminal can determine the TCI offset parameter based on the second indication information, and then determine the second TCI parameter based on the first TCI parameter and the TCI offset parameter, and the TCI offset parameter is essentially an offset of the TCI parameter, and generally requires fewer bits than the TCI parameter, so it is also beneficial to save the signaling overhead of the network device.

[0136] In some embodiments, the predefined rule can directly specify the TCI offset parameter, for example, the protocol specifies the specific value of the TCI offset parameter; or the predefined rule can indirectly specify the TCI offset parameter, for example, the predefined rule can specify that the parameter corresponding to a specific index in the table or list (which can be indicated by the network device or specified by the protocol) is the TCI offset parameter.

[0137] In some embodiments, the first indication information and / or the second indication information comprises at least one of the following:

[0138] Radio Resource Control (RRC) signaling;

[0139] Media Access Control Control Element (MAC CE);

[0140] Downlink Control Information (DCI).

[0141] In some embodiments, the first indication information comprises DCI; and the TCI offset parameter is determined based on the first predefined rule.

[0142] For example, the first indication information comprises DCI, the DCI can indicate the first power control parameter through an information field in the DCI, for example, the DCI can indicate the first power control parameter through a TPC (Transmit power control) information field, or also referred to as a TPC command information field.

[0143] The terminal can determine the power control offset parameter according to the first predefined rule, and then add or subtract the power control offset parameter on the basis of the first power control parameter, and the result can be used as the second power control parameter.

[0144] For example, the first power control parameter indicated by the first indication information is -1dB, and the power control offset parameter determined by the terminal according to the first predefined rule is 1dB, in the case that the second power control parameter is equal to the sum of the first power control parameter and the power control offset parameter, the second power control parameter = 1dB + (-1dB) = 0dB.

[0145] It should be noted that the power control offset parameter can correspond to different values for different types of power control parameters. For example, each type of power control parameter can correspond to one or more power control offset parameters, for example, the power control offset parameter can be included in a list or table, and the terminal can determine the index in the list or table based on the predefined rule or signaling, and then determine the power control offset parameter corresponding to the index in the list or table.

[0146] In some embodiments, the first indication information comprises DCI; and the second indication information comprises RRC or MAC CE.

[0147] For example, the first indication information comprises DCI, and the second indication information comprises RRC signaling or MAC CE. The DCI can indicate the first power control parameter through an information field in the DCI, for example, the DCI can indicate the power control offset parameter through a TPC information field. The RRC signaling and / or MAC CE can indicate the power control offset parameter, for example, the RRC signaling can indicate the power control offset parameter through an information element (IE). Then the terminal can add or subtract the power control offset parameter on the basis of the first power control parameter, and the result can be used as the second power control parameter.

[0148] For example, the first power control parameter indicated by the first indication information is -1dB, and the power control offset parameter determined by the terminal according to the second indication information is 1dB, in the case that the second power control parameter is equal to the sum of the first power control parameter and the power control offset parameter, the second power control parameter = 1dB + (-1dB) = 0dB.

[0149] In some embodiments, the network device can indicate the power control offset parameter in a direct indication manner, or can indicate the power control offset parameter in an indirect indication manner.

[0150] Taking the direct indication manner as an example, the network device can directly indicate the power control offset parameter through RRC signaling or MAC CE or DCI.

[0151] Taking the indirect indication manner as an example, the terminal can determine a power control offset parameter list based on RRC signaling or MAC CE or a first predefined rule, and then the terminal can determine the power control offset parameter indicated by the network device in the power control offset parameter list according to the MAC CE or DCI.

[0152] In some embodiments, the second indication information can be semi-static signaling such as RRC signaling or MAC CE, and the first indication information can be dynamic signaling such as DCI.

[0153] For semi-static signaling, the terminal generally receives it only when entering or leaving the RRC connected state, and the quantity is relatively small. For dynamic signaling, the network device can send it relatively frequently when scheduling the terminal to communicate in the RRC connected state, and the quantity is relatively small.

[0154] Therefore, by indicating the first power control parameter through dynamic signaling and indicating the power control offset parameter through semi-static signaling, it is not necessary to indicate the power control offset parameter or the second power control parameter through dynamic signaling, which is beneficial to saving the network device's overhead in dynamic signaling.

[0155] In some embodiments, the terminal can determine the SBFD time unit and the non-SBFD time unit, and then determine the power control parameter corresponding to the SBFD time unit and the power control parameter corresponding to the non-SBFD time unit in the first power control parameter and the second power control parameter according to a second predefined rule or indication information.

[0156] The first predefined rule and the second predefined rule can be different predefined rules, the first predefined rule is used to define the power control offset parameter, and the second predefined rule is used to define how to determine the power control parameter corresponding to the SBFD time unit and the power control parameter corresponding to the non-SBFD time unit in the first power control parameter and the second power control parameter. For example, the first predefined rule and the second predefined rule can both be protocol conventions.

[0157] For example, the terminal can determine the first power control parameter and the second power control parameter based on the method in any of the preceding embodiments. After determining the first power control parameter and the second power control parameter, the terminal can determine the power control parameter corresponding to the SBFD time unit and the power control parameter corresponding to the non-SBFD time unit based on the second predefined rule or the indication information.

[0158] For example, the power control parameter corresponding to the SBFD time unit is the first power control parameter, the power control parameter corresponding to the non-SBFD time unit is the second power control parameter, and the transmission includes PUSCH. The terminal can transmit the PUSCH based on the first power control parameter in the SBFD time unit and based on the second power control parameter in the non-SBFD time unit.

[0159] In some embodiments, the terminal can determine the time unit in which the transmission is located.

[0160] 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.

[0161] For example, the transmission parameter corresponding to the SBFD time unit is denoted 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 denoted as a second transmission parameter set (which can include one or more transmission parameters).

[0162] In the case of transmission in the SBFD time unit, the terminal can perform transmission based on the transmission parameter in the first transmission parameter set;

[0163] In the case of transmission in the non-SBFD time unit, the terminal can perform transmission based on the transmission parameter in the second transmission parameter set.

[0164] 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, 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.

[0165] In some embodiments, the terminal can determine the time domain location of the SBFD time unit based on the network device configuration and the corresponding rule. In the case that the terminal schedules data transmission in the SBFD time unit, the terminal determines that the data transmission corresponds to the SBFD time unit.

[0166] Taking a transmission of a PUSCH including a DCI scheduling as an example, if the terminal determines, based on DCI scheduling information, that the PUSCH is transmitted on a transmission occasion i.

[0167] If the terminal determines, based on network device configuration and corresponding rules, that the occasion i corresponds to an SBFD time unit, the terminal determines that the PUSCH is transmitted on the SBFD time unit. Exemplarily, transmission in the occasion i corresponds to an UL subband frequency domain range.

[0168] If the terminal determines, based on network device configuration or corresponding predefined rules, that the occasion i is non-SBFD, the terminal determines that the PUSCH is transmitted on a non-SBFD time unit. Exemplarily, transmission in the occasion i corresponds to an UL BWP frequency domain range.

[0169] Corresponding to uplink data in the transmission occasion i, if the occasion i contains both SBFD time units and non-SBFD time units, the terminal determines the type of time unit corresponding to the occasion i based on at least one of the following manners:

[0170] The terminal determines that the occasion i corresponds to an SBFD time unit, or the terminal determines that the occasion i corresponds to a non-SBFD time unit.

[0171] The terminal determines the type of time unit corresponding to the occasion i based on a first time unit corresponding to the occasion i. Exemplarily, if the first time unit is an SBFD time unit, the terminal determines that the type of time unit corresponding to the 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 the occasion i is non-SBFD.

[0172] The terminal determines that the occasion i corresponds to both SBFD time units and non-SBFD time units.

[0173] 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, and exemplarily, a conventional mechanism is used to determine corresponding power control parameters.

[0174] In some embodiments, the 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 in the slot for data transmission and a duration L of the transmission symbol. For Type B PUSCH repetition transmission, one PUSCH transmission occasion is a nominal repetition transmission, e.g., refer to 3GPP protocol [6, TS 38.214].

[0175] In some embodiments, the at least one power control parameter comprises a first power control parameter and a second power control parameter, and the second predefined rule comprises one of:

[0176] the first power control parameter is a power control parameter corresponding to the transmission in a non-SBFD time unit, and the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit;

[0177] the first power control parameter is a power control parameter corresponding to the transmission in a non-SBFD time unit, and the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit;

[0178] the first power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit and a non-SBFD time unit;

[0179] the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit and a non-SBFD time unit.

[0180] In some embodiments, the at least one power control parameter comprises a first power control parameter and a second power control parameter, and the indication information is used to indicate at least one of:

[0181] the first power control parameter is a power control parameter corresponding to the transmission in a non-SBFD time unit, and the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit;

[0182] the first power control parameter is a power control parameter corresponding to the transmission in a non-SBFD time unit, and the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit;

[0183] the first power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit and a non-SBFD time unit;

[0184] the second power control parameter is a power control parameter corresponding to the transmission in a SBFD time unit and a non-SBFD time unit.

[0185] In some embodiments, the at least one power control parameter comprises one power control parameter (e.g., the first power control parameter or the second power control parameter), and the determining the at least one power control parameter according to the predefined rule comprises at least one of the following:

[0186] the power control parameter is a power control parameter corresponding to the transmission in the SBFD time unit;

[0187] the power control parameter is a power control parameter corresponding to the transmission in the non-SBFD time unit;

[0188] the power control parameter is a power control parameter corresponding to the transmission in the SBFD time unit and the non-SBFD time unit.

[0189] In some embodiments, the at least one power control parameter comprises one power control parameter (e.g., the first power control parameter or the second power control parameter), and the determining the at least one power control parameter according to the predefined rule comprises at least one of the following:

[0190] the power control parameter is a power control parameter corresponding to the transmission in the SBFD time unit;

[0191] the power control parameter is a power control parameter corresponding to the transmission in the non-SBFD time unit;

[0192] the power control parameter is a power control parameter corresponding to the transmission in the SBFD time unit and the non-SBFD time unit.

[0193] In some embodiments, in the case that the at least one power control parameter comprises one power control parameter, and the power control parameter is a power control parameter corresponding to the transmission in the SBFD time unit, there is no corresponding power control parameter in the non-SBFD time unit, so that the terminal can ignore the transmission in the non-SBFD time unit.

[0194] In some embodiments, in the case that the at least one power control parameter comprises one power control parameter, and the power control parameter is a power control parameter corresponding to the transmission in the non-SBFD time unit, there is no corresponding power control parameter in the SBFD time unit, so that the terminal can ignore the transmission in the SBFD time unit.

[0195] In some embodiments, the transmission comprises at least one of the following: uplink transmission; downlink transmission.

[0196] In some embodiments, the uplink transmission comprises at least one of the following:

[0197] Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel);

[0198] Physical Uplink Shared Channel (PUSCH);

[0199] Sounding Reference Signal (SRS).

[0200] In some embodiments, the downlink transmission comprises at least one of:

[0201] Physical Downlink Control Channel (PDCCH);

[0202] Physical Downlink Shared Channel (PDSCH);

[0203] Channel State Information Reference Signal (CSI-RS);

[0204] Synchronization Signal Block (SSB).

[0205] In some embodiments, the power control parameter comprises at least one of:

[0206] the target received power, e.g., P0;

[0207] a path loss reference signal, or a path loss reference signal resource index, e.g., q d ;

[0208] a path loss adjustment coefficient, e.g., alpha;

[0209] 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;

[0210] a closed loop power control parameter f b,f,c (i, l), e.g., for uplink transmission PUSCH, in case of closed loop power control type accumulated, or, in case of closed loop power control type absolute, f b,f,c (i, l) = δPUSCH,b,f,c(i, l), where the subscript c denotes serving cell, f denotes carrier frequency, b denotes bandwidth part, and i denotes transmission occasion.

[0211] In some embodiments, the power control offset parameter comprises at least one of:

[0212] an accumulated power offset parameter, e.g., which can be used to determine a closed loop power control parameter δ of type accumulated;

[0213] an absolute power offset parameter, e.g., which can be used to determine a closed loop power control parameter δ of type absolute;

[0214] a power control index offset parameter, e.g., which can be used to determine a power control parameter of type closed loop power control index l.

[0215] Taking the accumulated power offset parameter as an example, the accumulated power offset parameter can be in units of dB, and the corresponding values can be 1 dB, -1 dB, 0 dB, 3 dB, -3 dB, 4 dB, -4 dB, etc.

[0216] Taking the absolute power offset parameter as an example, the power power offset parameter can be in units of dB, and the corresponding values can be -4 dB, -1 dB, 0 dB, 4 dB, 1 dB, 5 dB, -4 dB, 3 dB, -3 dB, 2 dB, -2 dB, etc.

[0217] Taking the power parameter index as an example, the power parameter index can be 0, 1, -1, 2, -2, etc.

[0218] It should be noted that the power control offset parameter is not limited to the several described in the above embodiments, and for different types of power control parameters, the power control offset parameter can be different, and the present disclosure does not limit this. For example, for transmit power, the power control offset parameter can include a transmit power offset parameter; for example, for a loss reference signal, the power control offset parameter can include a loss reference signal offset parameter; for example, for a loss adjustment coefficient, the power control offset parameter can include a loss adjustment coefficient offset parameter.

[0219] In some embodiments, taking an SRS including an uplink transmission as an example.

[0220] For example, alpha and P0 can be determined based on the SRS Resource set.

[0221] For example, q d may be configured based on RRC signaling or indicated based on MAC CE.

[0222] 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 a RAR UL grant, l = 0.

[0223] For example, the value range of the closed loop power control index l can be determined based on a signaling indication. For example, based on a 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 a PUSCH scheduled based on a RAR UL grant, l = 0. Wherein, RAR represents Random Access Response.

[0224] 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 corresponds to 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 by the TPC command based on the closed loop power control type, e.g. accumulation or absolute.

[0225] Table 1

[0226] For example, the accumulated value can be an accumulated δPUSCH,b,f,c(m,l) in dB, and the absolute value can be an absolute δPUSCH,b,f,c(m,l) in dB.

[0227] For example, δPUSCH,b,f,c(m,l) can be used to calculate the accumulated value

[0228] represents 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:

[0229] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission time i-i0, N = K PUSCH (i-i0)-1.

[0230] t2 = time corresponding to M OFDM symbols before PUSCH transmission occasion i, M = K PUSCH (i)..

[0231] where i0 > 0 is the smallest integer satisfying K PUSCH (i-i0) < K PUSCH (i) symbol condition.

[0232] 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.

[0233] 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 related documents, and the present disclosure does not elaborate on this parameter). For example, the k2 can be determined based on signaling indication, for example, based on PUSCH power control configuration (PUSCH-ConfigCommon) indication.

[0234] where if the first symbol of the PUSCH transmission occasion occurs after T (proc,2) corresponding to the time range, the UE can delay the application of the TPC command until after the T (proc,2) determined time range (outside the T (proc,2) determined time range).

[0320] In the fourth aspect, the embodiments of the present disclosure propose a parameter determination method. FIG. 4B is a schematic flowchart of a parameter determination method according to an embodiment of the present disclosure.

[0329] The technical solutions of the present disclosure are described below by way of several embodiments.

[0330] 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 transmit uplink data on an UL subband and / or receive downlink data on a DL subband based on a base station configuration on a DL or flexible symbol.

[0331] In some embodiments, the terminal supporting the SBFD feature can receive downlink data on a DL subband and / or transmit uplink data on an UL subband based on a base station configuration on an UL or flexible symbol.

[0332] 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.

[0333] 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.

[0334] The data transmission includes but is not limited to at least one of the following:

[0335] The uplink transmission includes but is not limited to PUSCH, SRS, PUCCH, etc.

[0336] The downlink transmission includes but is not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0337] The transmission parameter includes but is not limited to at least one of the following:

[0338] The power control related parameter;

[0339] The spatial relationship related parameter and / or the beam related parameter.

[0340] 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.

[0341] 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, 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.

[0342] 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.

[0343] 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 qd; path loss adjustment coefficient alpha; closed loop power control index l; closed loop power control parameter.

[0344] If the transmission parameter corresponds to a power control parameter set, the parameter set is composed of one or more of the parameters. The parameter set contains the power control parameters corresponding to one or more resources in the set.

[0345] 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.

[0346] If the transmission parameter corresponds to a spatial relation parameter set, the parameter set is composed of one or more of the parameters.

[0347] The parameter set contains the spatial relation parameters corresponding to one or more resources in the set.

[0348] In the following, the present application is based on different embodiments, taking the data transmission as the uplink transmission and the transmission parameter as the power control parameter as an example, to describe the specific schemes of the present application, which are 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.

[0349] Embodiment 1:

[0350] In some embodiments, the terminal receives the indication signaling, determines the first power control parameter and the second power control parameter corresponding to the SBFD time unit and / or the non-SBFD time unit.

[0351] The correspondence between the first power control parameter and the second power control parameter and the SBFD time unit and the non-SBFD time unit can be determined based on a predefined manner or based on signaling indication manner, and the present application does not limit this.

[0352] In order to reduce the corresponding indication signaling overhead as much as possible, in some embodiments, the terminal determines the corresponding first power control parameter based on the first power control parameter indication signaling, and determines the corresponding power offset parameter based on the predefined manner or the signaling indication manner. The terminal determines the corresponding second power control parameter indication signaling based on the first power control parameter and the power offset parameter.

[0353] The power control offset parameter includes but is not limited to: cumulative power offset parameter, absolute power offset parameter, power parameter index offset.

[0354] Taking the cumulative power offset parameter as an example, the power offset parameter can be in units of dB, and the corresponding values can be 1dB, -1dB, 0dB, 3dB, -3dB, 4dB, -4dB, etc.

[0355] Taking the absolute power offset parameter as an example, the power offset parameter can be in units of dB, and the corresponding values can be -4dB, -1dB, 0dB, 4dB, 1dB, 5dB, -4dB, 3dB, -3dB, 2dB, -2dB, etc.

[0356] Taking the power parameter index as an example, the parameter index can be 0, 1, -1, 2, -2, etc.

[0357] Sub-embodiment 1:

[0358] Taking the first power control parameter indication signaling as the TPC command field of the DCI and the first power control parameter indicated by the TPC command field as the cumulative power control parameter as an example, if the information field indicates that the first cumulative power parameter is equal to -1dB, if the terminal determines the cumulative power parameter offset parameter to be 1dB based on the predefined rule, the terminal determines the second cumulative power parameter to be 0dB.

[0359] The power offset parameter can be predefined with different tables based on different parameters, and the present application does not limit this.

[0360] Sub-embodiment 2:

[0361] The terminal determines the power control offset parameter based on the indication signaling. Exemplarily, the indication signaling can be RRC. Still taking the first power control parameter indication signaling as the TPC command field of DCI, and taking the first power control parameter indicated by the TPC command field as the accumulated power control parameter as an example, if the information field indicates that the first accumulated power parameter is equal to -1 dB, and if the terminal determines that the accumulated power parameter offset parameter is 1 dB based on the RRC signaling, the terminal determines that the second accumulated power parameter is equal to 0 dB.

[0362] Exemplarily, the indication signaling can be MAC CE or DCI. In some embodiments, the indication signaling directly indicates that the power offset parameter is 1 dB. Another possible indication manner is that the terminal determines a corresponding power offset parameter list based on RRC signaling, MAC CE or a predefined manner, and determines one of the list based on the MAC CE or DCI.

[0363] Taking the indication signaling as the TPC command field of 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.

[0364] Step 1: The terminal determines the first power control parameter and the second power control parameter based on the above indication scheme.

[0365] Step 2: The terminal determines the time unit type corresponding to the first power control parameter and the second power control parameter based on a predefined or signaling indication manner. Exemplarily, the first power control parameter is applied to the SBFD time unit, and the second power control parameter is applied to the non-SBFD time unit.

[0366] Step 3: The terminal determines the time unit applied to the PUSCH transmission based on the indication information. Exemplarily, 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.

[0367] Embodiment 2:

[0368] In some embodiments, the terminal receives indication signaling to determine the first power control parameter and / or the second power control parameter corresponding to the SBFD time unit and / or the non-SBFD time unit.

[0369] Exemplarily, the indication signaling indicates a corresponding power control parameter combination, and the power control parameter combination comprises at least one of the following:

[0370] a first power control parameter;

[0371] a second power control parameter;

[0372] the first power control parameter and the second power control parameter.

[0373] Exemplarily, the terminal receives the indication signaling, determines a corresponding power control parameter combination index, and determines the first power control parameter and the second power control parameter corresponding to the index based on the power control parameter combination index.

[0374] Exemplarily, the terminal determines the corresponding relationship between the power control parameter combination index and the corresponding power control parameter based on at least one of the following manners:

[0375] a predefined manner;

[0376] indication signaling, such as SI, RRC, MAC CE, DCI, etc.

[0377] The present application mainly designs the application scheme in the SBFD scenario, realizes the determination of the transmission parameter of data transmission on the SBFD time unit and the non-SBFD time unit on the basis of reducing the signaling overhead as much as possible, and thus improves the data transmission efficiency.
