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.

[0104] The disclosure is not limited to time units, and for example, can include at least one of the following: a frame, a subframe, a slot, a symbol, a sub-slot. The symbol can be, for example, an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0105] 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.

[0106] FIG. 1B is a schematic diagram of a subband according to an embodiment of the disclosure.

[0107] 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.

[0108] The network device can configure an 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.

[0109] 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.

[0110] 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 simultaneously perform uplink communication and downlink communication in a single time domain unit.

[0111] In some embodiments, in the communication process, the transmission (such as uplink transmission, downlink transmission, etc.) between the network device and the terminal can be performed on the SBFD time unit or the non-SBFD time unit, and in this case, the transmission needs to be based on the transmission parameter.

[0112] In this case, for the transmission, resources can be configured on the SBFD time unit and the non-SBFD time unit, and for each resource, a transmission parameter can be configured respectively.

[0113] For example, taking the transmission including sending a SRS (Sounding Reference Signal) as an example, the resource can include a resource set of the SRS, for example, denoted as SRS resource set. On this basis, for the SBFD, SRS resource set #1 needs to be configured, and for the non-SBFD, SRS resource set #2 needs to be configured, SRS resource set #1 corresponds to transmission parameter #1, and SRS resource set #2 corresponds to transmission parameter #2.

[0114] This way of configuring resources needs to configure SRS resource set for the SBFD time unit and the non-SBFD time unit respectively, which will occupy relatively more resources from the resource perspective, and will cause relatively large signaling overhead from the signaling overhead perspective.

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

[0116] As shown in FIG. 2, the parameter determination method can include the following steps:

[0117] In some embodiments, the terminal determines the SBFD time unit and the non-SBFD time unit.

[0118] For example, the terminal can determine a time unit configured with a subband as an SBFD time unit, and a time unit not configured with a subband as a non-SBFD time unit (i.e., a legacy time unit).

[0119] In some embodiments, the terminal can determine at least one set of transmission parameters corresponding to the SBFD time unit and the non-SBFD time unit, which can be one set of transmission parameters, or multiple sets of transmission parameters, for example, 2 sets of transmission parameters or more.

[0120] For example, one set of transmission parameters can include one or more transmission parameters, and the specific included transmission parameters are described in subsequent embodiments. For example, the types of transmission parameters included in each set of transmission parameters can be the same or different, and the present disclosure does not limit this.

[0121] 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 (e.g., a protocol agreement), or can be determined based on network device indication, and the present disclosure does not limit this.

[0122] In some embodiments, the terminal determines resources corresponding to the transmission between the terminal and the network device.

[0123] For example, the resources can be one or more time domain resources and / or frequency domain resources.

[0124] For example, the resources can include one or more resource sets.

[0125] For example, the resources can include one or more resource lists.

[0126] For example, taking the transmission including sending SRS as an example, the resources corresponding to the SRS can be SRS resources, and the SRS resources can indicate time domain resources and / or frequency domain resources for sending SRS.

[0127] In the case where the resources include resource sets, the resources corresponding to the SRS can be SRS resource sets, and the SRS resource sets can include SRS resources and can also include SRS (e.g., represented by the identity of the SRS).

[0128] In the case where the resources include resource lists, the resources corresponding to the SRS can be SRS resource lists, and the SRS resource lists can include SRS resources and can also include SRS (e.g., represented by the identity of the SRS).

[0129] If the resources corresponding to the SBFD time unit and the non-SBFD time unit are determined based on different transmission configurations,

[0130] For example, in the case of transmitting SRS, under the condition that the resources correspond to an SRS resource set, the terminal can determine at least one SRS resource for transmission on the SBFD time unit based on the first SRS resource set and at least one SRS resource for transmission on the non-SBFD time unit based on the second SRS resource set.

[0131] For example, in the case of transmitting SRS, under the condition that the resources correspond to an SRS resource list, the terminal can determine at least one SRS resource for transmission on the SBFD time unit based on the first SRS resource list and at least one SRS resource for transmission on the non-SBFD time unit based on the second SRS resource list.

[0132] For example, in the case of transmitting SRS, under the condition that the resources correspond to an SRS resource, the terminal can determine one SRS resource for transmission on the SBFD time unit based on the first SRS resource and one SRS resource for transmission on the non-SBFD time unit based on the second SRS resource; the first SRS resource and the second SRS resource can belong to the same SRS resource set or resource list, or correspond to different SRS resource sets or resource lists.

[0133] If the resources corresponding to the SBFD time unit and the non-SBFD time unit are determined based on the same transmission configuration:

[0134] For example, in the case of transmitting SRS, under the condition that the resources correspond to an SRS resource set, the terminal can determine at least one SRS resource for transmission on the SBFD time unit and at least one SRS resource for transmission on the non-SBFD time unit based on one SRS resource set; the SRS resources corresponding to the SBFD time unit and the non-SBFD time unit can be the same or different.

[0135] For example, in the case of transmitting SRS, under the condition that the resources correspond to an SRS resource list, the terminal can determine at least one SRS resource for transmission on the SBFD time unit and at least one SRS resource for transmission on the non-SBFD time unit based on one SRS resource list; the SRS resources corresponding to the SBFD time unit and the non-SBFD time unit can be the same or different.

[0136] For example, in the case of transmission including SRS, under the condition that the resource corresponds to SRS resource, the terminal can determine at least one SRS resource on the SBFD time unit and the non-SBFD time unit based on one SRS resource (for example, frequency domain resource, time domain resource, space domain resource, code domain resource, etc.) simultaneously, and the SRS resources corresponding to the SBFD time unit and the non-SBFD time unit can be the same or different.

[0137] In step S201, the terminal determines the transmission parameters corresponding to the resource in the SBFD time unit and / or the non-SBFD time unit in at least one set of transmission parameters according to the predefined rule or the indication information.

[0138] In step S202, the terminal transmits in the SBFD time unit and / or the non-SBFD time unit according to the transmission parameters corresponding to the resource in the SBFD time unit and / or the non-SBFD time unit.

[0139] In some embodiments, since the network device needs to perform uplink communication and downlink communication in the SBFD time unit, and only needs to perform uplink communication or downlink communication in the non-SBFD time unit, the antenna, transmission environment, interference condition, etc. configured by the network device for transmission in the SBFD time unit and the non-SBFD time unit are different, and the corresponding transmission parameters need to be based on the corresponding transmission parameters to facilitate meeting the communication requirements.

[0140] As described above, for transmission in the SBFD time unit and the non-SBFD time unit, due to the difference in the configured antenna, transmission environment, interference condition, 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.

[0141] Taking the power control parameter as an example, to realize the power control configuration of the SBFD time unit and / or the non-SBFD time unit respectively, a possible implementation manner 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 parameter is configured based on a specific resource and / or a resource set to which the resource belongs, based on the above configuration, the power control of the SBFD time unit and the non-SBFD time unit can be realized respectively. However, the above manner is at the cost of increasing the resource set configuration overhead. Taking the SRS resource set as an example, in the related mechanism, for the usage (usage) of codebook or non-codebook in the sTRP scenario, the number of configurable SRS resource sets is usually 1. If 2 SRS resource sets are configured, the mTRP scenario or the non-mTRP scenario can be corresponded, and the present disclosure does not limit this.

[0142] For a specific BWP, the maximum number of configurable SRS resource sets is 16. Different SRS resource sets are configured based on the SBFD time unit and the non-SBFD time unit. On the basis of ensuring the existing performance, the required set overhead may be doubled.

[0143] According to an embodiment of the present disclosure, the network device can configure the same resource for the transmission of the terminal on the SBFD time unit and the non-SBFD time unit. For this resource, the transmission parameter corresponding to the SBFD time unit can be determined, and / or the transmission parameter corresponding to the non-SBFD time unit can be determined, so that the terminal can perform transmission based on the transmission parameter corresponding to the SBFD time unit on the SBFD time unit based on the resource on the SBFD time unit, and perform transmission based on the transmission parameter corresponding to the non-SBFD time unit on the non-SBFD time unit based on 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.

[0144] Since the same resource is configured for the transmission of the terminal on the SBFD time unit and the non-SBFD time unit, from the resource point of view, it is beneficial to save resources, and from the signaling overhead point of view, it is beneficial to reduce the signaling overhead.

[0145] In some embodiments, the terminal can determine the time unit in which the transmission is located.

[0146] 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.

[0147] For example, the corresponding transmission parameters on the SBFD time unit are recorded as a first set of transmission parameters (which can include one or more transmission parameters), and the corresponding transmission parameters on the non-SBFD time unit are recorded as a second set of transmission parameters (which can include one or more transmission parameters).

[0148] 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;

[0149] 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.

[0150] In some embodiments, the terminal can directly determine the time unit in which the transmission is located according to the network device indication; or the terminal can indirectly determine the time unit in which the transmission is located according to the scheduling information used to schedule the transmission, for example, if the scheduling information is located in the SBFD time unit, the terminal can determine that the transmission scheduled by the scheduling information is also in the SBFD time unit, for example, if the scheduling information is located in the non-SBFD time unit, the terminal can determine that the transmission scheduled by the scheduling information is also in the non-SBFD time unit.

[0151] In some embodiments, taking the case of including two sets of transmission parameters in at least one set of transmissions as an example.

[0152] For example, the network device can configure two sets of transmission parameters for the terminal through RRC (Radio Resource Control) signaling, MAC CE (Media Access Control Control Element), DCI (Downlink Control Information), etc. Further, the network device can indicate the two sets of transmission parameters through the IE (Information Element) or information field in the signaling.

[0153] Taking the transmission including SRS as an example, the two sets of transmission parameters indicated by the network device through the IE are SRI-PUSCH-MappingToAddModList1 and SRI-PUSCH-MappingToAddModList2, where SRI stands for SRS resource indication (SRS resource indication). For example, SRI-PUSCH-MappingToAddModList1 can be recorded as a first set of power control parameters, and SRI-PUSCH-MappingToAddModList2 can be recorded as a second set of power control parameters.

[0154] For example, two sets of transmission parameters can be determined based on a predefined rule. For example, for two sets of power control parameters Uplink-PowerControl determined based on a predefined rule, one of the sets of power control parameters has an index of 1, i.e., Uplink-PowerControlId1, and the other set of power control parameters has an index of 2, i.e., Uplink-PowerControlId2.

[0155] The predefined rule can provide that the first set of power control parameters has a smaller corresponding index relative to the second set of power control parameters, and then it can be determined that the Uplink-PowerControl corresponding to Uplink-PowerControlId1 is the first set of power control parameters, and the Uplink-PowerControl corresponding to Uplink-PowerControlId2 is the second set of power control parameters.

[0156] Alternatively, the predefined rule can provide that the second set of power control parameters has a smaller index relative to the first set of power control parameters, and then it can be determined that the Uplink-PowerControl corresponding to Uplink-PowerControlId2 is the first set of power control parameters, and the Uplink-PowerControl corresponding to Uplink-PowerControlId1 is the second set of power control parameters.

[0157] The following will be exemplarily described through several embodiments based on the predefined rule, the terminal determines the transmission parameters corresponding to the SBFD time unit and the non-SBFD time unit for the resource in at least one set of transmission parameters.

[0158] In some embodiments, the at least one set of transmission parameters includes a first set of transmission parameters and a second set of transmission parameters, and the predefined rule includes at least one of the following:

[0159] The first set of transmission parameters is a set of transmission parameters corresponding to the SBFD time unit for the resource, and the second set of transmission parameters is a set of transmission parameters corresponding to the non-SBFD time unit for the resource;

[0160] The first set of transmission parameters is a set of transmission parameters corresponding to the non-SBFD time unit for the resource, and the second set of transmission parameters is a set of transmission parameters corresponding to the SBFD time unit for the resource;

[0161] The first set of transmission parameters is a set of transmission parameters corresponding to the SBFD time unit and the non-SBFD time unit for the resource;

[0162] The second set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit.

[0163] In some embodiments, the at least one set of transmission parameters includes one set of transmission parameters, wherein the following at least one is included according to a predefined rule:

[0164] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit.

[0165] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit.

[0166] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit.

[0167] For example, in the case that the at least one set of transmission parameters includes one set of transmission parameters, and the set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit, there is no set of transmission parameters corresponding to the resource in the non-SBFD time unit, so that the terminal can ignore the transmission in the non-SBFD time unit.

[0168] For example, in the case that the at least one set of transmission parameters includes one set of transmission parameters, and the set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit, there is no set of transmission parameters corresponding to the resource in the SBFD time unit, so that the terminal can ignore the transmission in the SBFD time unit.

[0169] The following is an exemplary description of the terminal determining the set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit in the at least one set of transmission parameters based on the indication information through several embodiments. For example, the indication information includes but is not limited to RRC signaling, MAC CE, DCI.

[0170] In some embodiments, the at least one set of transmission parameters includes a first set of transmission parameters and a second set of transmission parameters, wherein the indication information is used to indicate at least one of the following:

[0171] The first set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit, and the second set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit.

[0172] The first set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit, and the second set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit.

[0173] The first set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit.

[0174] The second set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit.

[0175] In some embodiments, the at least one set of transmission parameters includes one set of transmission parameters, and the indication information is used to indicate at least one of the following:

[0176] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit.

[0177] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit.

[0178] The set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit and the non-SBFD time unit.

[0179] For example, in a case where the at least one set of transmission parameters includes one set of transmission parameters, and the set of transmission parameters is a set of transmission parameters corresponding to the resource in the SBFD time unit, there is no set of transmission parameters corresponding to the resource in the non-SBFD time unit, so that the terminal can ignore the transmission in the non-SBFD time unit.

[0180] For example, in a case where the at least one set of transmission parameters includes one set of transmission parameters, and the set of transmission parameters is a set of transmission parameters corresponding to the resource in the non-SBFD time unit, there is no set of transmission parameters corresponding to the resource in the SBFD time unit, so that the terminal can ignore the transmission in the SBFD time unit.

[0181] In some embodiments, the transmission includes a transmission between the terminal and multiple Transmission Reception Points (TRPs) of the network device.

[0182] In some embodiments, determining the resource corresponding to the transmission between the terminal and the network device includes: determining the resource corresponding to the transmission between the terminal and each TRP, respectively.

[0183] In a multi-TRP (mTRP) scenario, the terminal can communicate with multiple TRPs based on the signaling configuration, for example, the multiple TRPs can include 2 TRPs. For each TRP, the transmission can correspond to different resources, for example, for 2 TRPs (TRP#1, TRP#2), the transmission can correspond to two resources, one resource corresponding to TRP#1 and the other resource corresponding to TRP#2.

[0184] For example, taking the transmission including SRS, the resource including SRS resource set as an example, when the terminal communicates with TRP#1, SRS can be transmitted based on SRS resource set#1, and when the terminal communicates with TRP#2, SRS can be transmitted based on SRS resource set#2.

[0185] Further, the transmission parameter set corresponding to the SBFD time unit and the non-SBFD time unit of different SRS resource sets can be different. For example, SRS resource set#1 corresponds to transmission parameter set#1 in the SBFD time unit, and SRS resource set#1 corresponds to transmission parameter set#2 in the non-SBFD time unit; SRS resource set#2 corresponds to transmission parameter set#3 in the SBFD time unit, and SRS resource set#2 corresponds to transmission parameter set#4 in the non-SBFD time unit.

[0186] When the terminal communicates with TRP#1 in the SBFD time unit, SRS can be transmitted based on transmission parameter set#1 and SRS resource set#1; when the terminal communicates with TRP#1 in the non-SBFD time unit, SRS can be transmitted based on transmission parameter set#2 and SRS resource set#1; when communicating with TRP#2 in the SBFD time unit, SRS can be transmitted based on transmission parameter set#3 and SRS resource set#2; and when the terminal communicates with TRP#2 in the non-SBFD time unit, SRS can be transmitted based on transmission parameter set#4 and SRS resource set#2.

[0187] In some embodiments, in a multi-TRP (mTRP) scenario, different resources can also be configured for SBFD time units and non-SBFD time units.

[0188] For example, the terminal communicates with two TRPs (TRP #1 and TRP #2) to transmit SRS, and the resources include SRS resource sets. Due to SBFD time units and non-SBFD time units, SRS resource sets need to be configured respectively for SBFD time units and non-SBFD time units involved in the terminal communicating with TRP #1, such as SRS resource set #1 and SRS resource set #2; and SRS resource sets need to be configured respectively for SBFD time units and non-SBFD time units involved in the terminal communicating with TRP #2, such as SRS resource set #3 and SRS resource set #4.

[0189] Further, each SRS resource set can correspond to a set of transmission parameters respectively, and for the above four SRS resource sets, four sets of transmission parameters can be corresponded, such as SRS resource set #1 corresponds to set of transmission parameters #1, SRS resource set #2 corresponds to set of transmission parameters #2, SRS resource set #3 corresponds to set of transmission parameters #3, and SRS resource set #4 corresponds to set of transmission parameters #4.

[0190] The terminal can send SRS based on set of transmission parameters #1 and SRS resource set #1 when communicating with TRP #1 in SBFD time units; the terminal can send SRS based on set of transmission parameters #2 and SRS resource set #2 when communicating with TRP #1 in non-SBFD time units; the terminal can send SRS based on set of transmission parameters #3 and SRS resource set #3 when communicating with TRP #2 in SBFD time units; and the terminal can send SRS based on set of transmission parameters #4 and SRS resource set #4 when communicating with TRP #2 in non-SBFD time units.

[0191] The above embodiments mainly take the transmission as uplink transmission, and the uplink transmission is exemplarily described as SRS for the technical solutions of the present disclosure. The transmission in the embodiments of the present disclosure is not limited to SRS, and the transmission is exemplarily described through several embodiments as follows.

[0192] In some embodiments, the transmission includes at least one of the following: uplink transmission; downlink transmission.

[0193] In some embodiments, the uplink transmission includes at least one of the following:

[0194] Physical Uplink Control Channel (PUCCH);

[0195] Physical Uplink Shared Channel (PUSCH);

[0196] Sounding Reference Signal (SRS).

[0197] In some embodiments, the downlink transmission comprises at least one of:

[0198] Physical Downlink Control Channel (PDCCH);

[0199] Physical Downlink Shared Channel (PDSCH);

[0200] Channel State Information Reference Signal (CSI-RS);

[0201] Synchronization Signal Block (SSB).

[0202] The following illustrates the transmission in the set of transmission parameters by several embodiments.

[0203] In some embodiments, the type of the parameter in the set of transmission parameters comprises at least one of:

[0204] Power control parameter;

[0205] Spatial relation parameter.

[0206] In some embodiments, the spatial relation parameter comprises at least one of:

[0207] Cell to which the spatial relation applies;

[0208] Bandwidth Part (BWP) to which the spatial relation applies;

[0209] Resource to which the spatial relation applies;

[0210] Spatial relation reference signal;

[0211] Quasi Co-located type.

[0212] Exemplarily, the spatial relation reference signal includes, but is not limited to, SRS, CSI-RS, SSB.

[0213] In some embodiments, the power control parameter includes at least one of:

[0214] Target received power, for example, P0;

[0215] Path loss reference signal, or path loss reference signal resource index, for example, q d ;

[0216] Path loss adjustment coefficient, for example, alpha;

[0217] Closed loop power control index l, which can be referred to as data power control adjustment state index, for example, the value can be 1 or 0, and the data can include PUSCH, PUCCH, SRS and other transmissions;

[0218] Closed loop power control parameter f b,f,c (i, l), for example, for uplink transmission PUSCH, in the case of accumulated closed loop power control type, Or, in the case of absolute closed loop power control type, f b,f,c (i, l) = δPUSCH,b,f,c(i, l), wherein the subscript c represents the serving cell, f represents the carrier frequency, b represents the bandwidth part, and i represents the transmission occasion.

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

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

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

[0222] For example, the value range of the closed loop power control index l can be determined based on signaling indication. Exemplarily, 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).

[0223] 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 based on the closed loop power control type, e.g., accumulation or absolute.

[0224] Table 1

[0225] For example, the accumulated value can be accumulated δPUSCH,b,f,c(m,l) in dB, and the absolute value can be absolute δPUSCH,b,f,c(m,l) in dB.

[0226] For example, δPUSCH,b,f,c(m,l) can be used to calculate the accumulated value

[0227] represents the sum of the accumulated powers of δPUSCH,b,f,c(m,l) indicated by the m TPC commands corresponding to the index l in a period of time (e.g., t1 to t2). Wherein:

[0228] t1 = the time corresponding to the N OFDM symbols before the PUSCH transmission time i-i0, N = K PUSCH (i-i0)-1.

[0229] t2 = the time corresponding to the M OFDM symbols before the PUSCH transmission time i, M = K PUSCH (i).

[0230] Wherein, i0>0 is the minimum integer satisfying the symbol K PUSCH (i-i0) before the PUSCH transmission time i. PUSCH (i) symbol condition.

[0231] 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.

[0232] For CG (Configured Grant) PUSCH, K PUSCH (i) corresponds to the number of symbols in each slot a product of a minimum value determined by a parameter k2 (which can be referred to in the related documents, and the present disclosure will not repeat it) and a minimum value determined by a parameter k1. Exemplarily, the k2 can be determined based on signaling indication, for example, based on PUSCH power control configuration (PUSCH-ConfigCommon) indication.

[0233] wherein, if a first symbol of the PUSCH transmission occasion occurs after a last symbol of the PDCCH reception by T (proc,2) In the corresponding time range, the UE can delay the application of the TPC command until after the UE satisfies the T (proc,2) In the corresponding time range, the UE can delay the application of the TPC command until after the UE satisfies the T (proc,2) In the corresponding time range, the UE can delay the application of the TPC command until after the UE satisfies the T (proc,2) The Tpreparation is a preparation time for PUSCH, which is determined based on terminal capability.

[0234] The communication method related to the embodiments of the present disclosure can include at least one of steps S201-S202. For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, steps S201+S202 can be implemented as an independent embodiment, but not limited thereto.

[0235] In some embodiments, steps S201 and S202 can be exchanged in order or executed simultaneously.

[0236] In some embodiments, step S201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0237] In some embodiments, step S202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0282] The second aspect and optional implementation of the optional embodiment of the second aspect can refer to the optional implementation of the embodiment shown in FIG. 2 and other associated parts in the embodiment related to FIG. 2, which will not be described here.

[0283] The technical solutions of the present disclosure are further illustrated by several embodiments as follows.

[0284] In some embodiments, the terminal in the present disclosure can include a conventional terminal, or a Rel-18 and later version terminal, and the terminal is a terminal supporting the SBFD feature. The terminal can transmit uplink data on the UL subband and / or receive downlink data on the DL subband based on the base station configuration on the DL or flexible symbol.

[0285] In another possible implementation, the terminal supporting the SBFD feature can receive downlink data on the DL subband and / or transmit uplink data on the UL subband based on the base station configuration on the UL or flexible symbol.

[0286] 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 DCI-scheduled PUSCH as an example, if the terminal determines that the PUSCH is transmitted on time unit n based on the DCI scheduling information. Correspondingly, if the terminal determines that the time unit n 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 transmission is within the UL subband frequency domain range corresponding to the time unit n. 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 transmission is within the UL BWP frequency domain range corresponding to the time unit n.

[0287] As described above, in the SBFD scenario, based on the same resource parameter, the embodiment of the present application determines the transmission parameters related to the data transmission in the SBFD time unit and the non-SBFD time unit, and the resource parameter includes but is not limited to at least one of the following:

[0288] a resource set;

[0289] a resource list;

[0290] a resource.

[0291] The data transmission includes but is not limited to at least one of the following:

[0292] uplink transmission, including but not limited to PUSCH, SRS, PUCCH, etc.

[0293] downlink transmission, including but not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0294] The transmission parameter includes but is not limited to at least one of the following:

[0295] power control related parameters;

[0296] spatial relationship related parameters, and / or, beam related parameters.

[0297] In the following, the embodiment of the present application takes 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.

[0298] 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 parameter and / or the spatial relation parameter on the corresponding SBFD time unit and the non-SBFD time unit may be different. Taking the power control parameter as an example, to realize the power control configuration of the SBFD time unit and / or the non-SBFD time unit respectively, one possible time manner is to configure different resource parameters based on the SBFD time unit and the non-SBFD time unit respectively, for example, to configure different resource sets respectively. Based on this, the SBFD time unit and the non-SBFD time unit can be realized to correspond to different configuration resources. Considering that in the existing mechanism, the corresponding power control parameter is configured based on a specific resource and / or a resource set to which the resource belongs, based on the above configuration, the power control of the SBFD time unit and the non-SBFD time unit can be realized respectively. However, the above manner is at the cost of increasing the resource set configuration overhead. Taking the SRS resource set as an example, in the existing mechanism, for the sTRP scenario, if the usage is codebook or non-codebook, the number of the configurable SRS resource set is usually 1, if 2 SRS resource sets are configured, the corresponding mTRP scenario is configured. For a specific BWP, the maximum number of the configurable SRS resource set is 16. Based on the SBFD time unit and the non-SBFD time unit respectively configuring different SRS resource sets, on the basis of ensuring the existing performance, the required set overhead may be doubled.

[0299] Based on the above analysis, the present application mainly considers that based on the same resource parameter, e.g., a resource set, a resource list or a resource, the SBFD time unit and / or the non-SBFD time unit corresponding transmission parameters are configured at the same time to reduce the corresponding resource configuration overhead.

[0300] If the transmission parameter corresponds to the power control parameter, the parameter includes but is not limited to:

[0301] Target received power P0;

[0302] Loss reference signal q d ;

[0303] Loss adjustment coefficient alpha;

[0304] Closed loop power control index;

[0305] Closed loop power control parameter.

[0306] If the transmission parameter corresponds to a set of power control parameters, the set of parameters consists of one or more of the parameters. The set of parameters includes power control parameters corresponding to one or more resources in the set.

[0307] If the transmission parameter corresponds to a spatial relation related parameter, the parameter includes but is not limited to:

[0308] Applying a cell corresponding to a spatial relation parameter;

[0309] Applying a BWP corresponding to a spatial relation parameter;

[0310] Spatial relation reference signal;

[0311] SRS resource corresponding to a spatial relation parameter;

[0312] QCL type.

[0313] If the transmission parameter corresponds to a set of spatial relation parameters, the set of parameters consists of one or more of the parameters.

[0314] The set of parameters includes spatial relation parameters corresponding to one or more resources in the set.

[0315] From the perspective of the terminal, the terminal simultaneously obtains the transmission parameters corresponding to the SBFD time unit and / or non-SBFD time unit based on the same resource parameter, and determines the parameters corresponding to the data transmission based on the time type in which the data transmission is located. In the following, the present application is based on different embodiments, taking data transmission as uplink transmission and transmission parameter as a set of power control parameters as an example to illustrate specific solutions for the terminal to determine the relevant transmission parameters of the corresponding data transmission in the SBFD time unit and / or non-SBFD time unit. It should be noted that the corresponding data transmission can also be downlink transmission, and the transmission parameter can also be a set of power control parameters, spatial relation parameters, etc., and the present application does not limit this.

[0316] Embodiment 1:

[0317] The terminal determines the power control parameters of the corresponding uplink data in the SBFD time unit and non-SBFD time unit based on the first power control parameter (set) and / or the second power control parameter (set) of the same resource parameter (e.g., the same resource set or the same resource) determined by the terminal based on the configuration.

[0318] Step 1: For example, the terminal determines the first power control parameter set and / or the second power control parameter set based on the configuration or the predefined rule.

[0319] In the case of configuration, the terminal determines the first set of power control parameters and the second set of power control parameters based on the corresponding IE of the set of power control parameters, e.g., SRI-PUSCH-MappingToAddModList1, SRI-PUSCH-MappingToAddModList2, the list1 corresponds to the first set of power control parameters, and the list2 corresponds to the second set of power control parameters.

[0320] In the case of predefinition, the terminal determines the first set of power control parameters and the second set of power control parameters based on the corresponding index of the set of power control parameters. For example, the terminal determines that the index corresponding to the first set of power control parameters is smaller than the index corresponding to the second set of power control parameters based on a predefined rule. For example, the terminal determines that the index corresponding to the first set of power control parameters is larger than the index corresponding to the second set of power control parameters based on a predefined rule. For example, if Uplink-PowerControlId1 is smaller than Uplink-PowerControlId2, the terminal determines that the Uplink-PowerControl corresponding to Uplink-PowerControlId1 corresponds to the first set of power control parameters, and the Uplink-PowerControl corresponding to Uplink-PowerControlId2 corresponds to the second set of power control parameters.

[0321] Step 2: For example, the terminal determines the relationship between the first set of power control parameters and / or the second set of power control parameters and the SBFD time unit and the non-SBFD time unit based on a predefined rule.

[0322] In the case where the terminal determines the first set of power control parameters and the second set of power control parameters based on configuration, the predefined relationship includes one or more of the following:

[0323] The first set of power control parameters corresponds to the uplink transmission corresponding to the SBFD time unit, and the second set of power control parameters corresponds to the uplink transmission corresponding to the non-SBFD time unit.

[0324] The second set of power control parameters corresponds to the uplink transmission corresponding to the non-SBFD time unit, and the second set of power control parameters corresponds to the uplink transmission corresponding to the SBFD time unit.

[0325] The first set of power control parameters corresponds to the uplink transmission corresponding to the SBFD time unit and the uplink transmission corresponding to the non-SBFD time unit.

[0326] The second set of power control parameters corresponds to the uplink transmission corresponding to the SBFD time unit and the uplink transmission corresponding to the non-SBFD time unit.

[0327] In a condition that the terminal determines to configure the first set of power control parameters or the second set of power control parameters, taking the configuration of the first set of power control parameters as an example, the predefined relationship includes one or more of the following:

[0328] The first set of power control parameters corresponds to SBFD time unit corresponding uplink transmission.

[0329] The terminal ignores non-SBFD time unit corresponding uplink transmission.

[0330] The first set of power control parameters corresponds to SBFD time unit corresponding uplink transmission

[0331] The terminal ignores non-SBFD time unit corresponding uplink transmission.

[0332] The first set of power control parameters corresponds to SBFD time unit corresponding uplink transmission and non-SBFD time unit corresponding uplink transmission.

[0333] The above predefined rule can also be applied to the second set of power control parameters, which is not limited by the present application.

[0334] Step 3: As described above, the terminal determines the power control parameters corresponding to the current data transmission based on the relationship between the first set of power control parameters and / or the second set of power control parameters and SBFD time unit and non-SBFD time unit.

[0335] As described above, the terminal determines the time unit type of the current data transmission based on the base station configuration or the corresponding predefined rule. And based on the corresponding relationship between the time unit type and the set of power control parameters, the terminal determines the set of power control parameters corresponding to the data transmission.

[0336] In a condition that the set of power control parameters contains multiple resource power control parameters and / or multiple power control parameters of the same resource, the terminal determines the resource corresponding to the data transmission or the corresponding power control parameter based on the signaling indication or the predefined rule, and then determines the power control parameter corresponding to the data transmission, which is not described again.

[0337] mTRP scenario:

[0338] In the mTRP scenario, the terminal transmits based on the signaling configuration with multiple TRPs. In the existing mechanism, up to 2 TRPs can be supported for transmission, and the different TRPs correspond to different resource sets.

[0339] In the mTRP scenario, the terminal can determine two resource sets corresponding to the two TRPs based on the configuration, e.g., SRS resource set, and determine the power control parameters of the terminal in the uplink transmission of the corresponding TRP in the corresponding time unit based on the first power control parameter set and / or the second parameter set in each resource set. The present application will not be described here.

[0340] The embodiment of the present application mainly designs a pre-defined rule to determine the power control parameters of data transmission in the SBFD time unit and the non-SBFD time unit in the SBFD scenario. While effectively reducing the resource parameter configuration resources, the efficient determination of the power control parameters is realized.

[0341] Embodiment 2:

[0342] In the terminal, the first power control parameter (set) and / or the second power control parameter (set) of the same resource parameter (e.g., the same resource set or the same resource) are determined based on the configuration. The terminal determines the power control parameters of the corresponding uplink data in the SBFD time unit and the non-SBFD time unit based on the indication signaling.

[0343] Step 1: For example, the terminal determines the first power control parameter set and / or the second power control parameter set based on the configuration or the pre-defined rule.

[0344] For example, the terminal determines the first power control parameter set and the second power control parameter set based on the corresponding IE of the power control parameter set, e.g., SRI-PUSCH-MappingToAddModList1, SRI-PUSCH-MappingToAddModList2. The list1 corresponds to the first power control parameter set, and the list2 corresponds to the second power control parameter set.

[0345] For example, the terminal determines the first power control parameter set and the second power control parameter set based on the corresponding index of the power control parameter set. For example, the terminal determines that the index corresponding to the first power control parameter set is smaller than the index corresponding to the second power control parameter set based on the pre-defined rule. And / or, the terminal determines that the index corresponding to the first power control parameter set is greater than the index corresponding to the second power control parameter set based on the pre-defined rule. For example, if Uplink-PowerControlId1 is smaller than Uplink-PowerControlId2, the terminal determines that the Uplink-PowerControl corresponding to Uplink-PowerControlId1 corresponds to the first power control parameter set, and the Uplink-PowerControl corresponding to Uplink-PowerControlId2 corresponds to the second power control parameter set.

[0346] Step2: The terminal determines the relationship between the first set of power control parameters and / or the second set of power control parameters and the SBFD time unit and the non-SBFD time unit based on the signaling indication.

[0347] The indication signaling can include RRC, MAC CE or DCI, and the present application does not limit this;

[0348] When the terminal determines to configure the first set of power control parameters and the second set of power control parameters, the indication signaling is used to indicate one or more of the following states:

[0349] The first set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission, and the second set of power control parameters corresponds to the non-SBFD time unit corresponding uplink transmission;

[0350] The second set of power control parameters corresponds to the non-SBFD time unit corresponding uplink transmission, and the second set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission;

[0351] The first set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission and the non-SBFD time unit corresponding uplink transmission;

[0352] The second set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission and the non-SBFD time unit corresponding uplink transmission;

[0353] When the terminal determines to configure the first set of power control parameters or the second set of power control parameters, taking the configuration of the first set of power control parameters as an example, the indication signaling is used to indicate one or more of the following states:

[0354] The first set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission

[0355] The terminal ignores the non-SBFD time unit corresponding uplink transmission;

[0356] The first set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission

[0357] The terminal ignores the non-SBFD time unit corresponding uplink transmission;

[0358] The first set of power control parameters corresponds to the SBFD time unit corresponding uplink transmission and the non-SBFD time unit corresponding uplink transmission;

[0359] The above-mentioned predefined rules can also be applied to the second set of power control parameters, and the present application does not limit this.

[0360] Step3: The terminal determines the power control parameter corresponding to the current data transmission based on the relationship between the first power control parameter set and / or the second power control parameter set and the SBFD time unit and the non-SBFD time unit, as described above.

[0361] 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 power control parameter set corresponding to the data transmission based on the corresponding relationship between the time unit type and the power control parameter set.

[0362] Under the condition that the power control parameter set contains multiple resource power control parameters and / or multiple power control parameters of the same resource, the terminal determines the resource corresponding to the data transmission or the corresponding power control parameter based on the signaling indication or the predefined rule, and then determines the power control parameter corresponding to the data transmission, which will not be described in detail in the present application.

[0363] mTRP scenario:

[0364] In the mTRP scenario, the terminal transmits based on the signaling configuration with multiple TRPs. In the existing mechanism, up to 2 TRP transmission can be supported, and the different TRPs correspond to different resource sets.

[0365] In the mTRP scenario, the terminal can determine the two resource sets corresponding to the two TRPs based on the configuration, e.g., SRS resource set, and determine the power control parameter of the terminal's uplink transmission in the corresponding time unit of the corresponding TRP based on the first power control parameter set and / or the second parameter set in each resource set, which will not be described in detail in the present application.

[0366] The embodiment of the present application mainly designs a signaling indication method to determine the power control parameters of the data transmission in the SBFD time unit and the non-SBFD time unit respectively in the SBFD scenario. While effectively reducing the resource parameter configuration resource, the efficient determination of the power control parameter is realized.

[0367] Implementation method 3:

[0368] In the mTRP scenario, to realize the terminal's uplink transmission in different TRPs and different time unit types, another possible implementation method is that the terminal configures the uplink power control parameters of different TRPs and / or different time unit types based on different resource parameters.

[0369] Taking the TRPs that the terminal can transmit as an example, the TRPs include TRP1 and TRP2, taking time units that the terminal can transmit as an example, the time units include SBFD time units and non-SBFD time units, taking the resource parameters corresponding to a resource set as an example, in one possible implementation, the terminal determines one or more of the first / second / third / fourth resource sets based on configuration. The first / second / third / fourth resource sets correspond to the first / second / third / fourth set of power control parameters respectively, and the correspondence between the set of power control parameters and the TRP and the SBFD time unit is determined based on signaling indication or a predefined manner. Exemplarily, the predefined rule includes:

[0370] The first set of power control parameters corresponds to the corresponding uplink transmission of TRP1 SBFD time units, the second set of power control parameters corresponds to the corresponding uplink transmission of TRP1 non-SBFD time units, the first set of power control parameters corresponds to the corresponding uplink transmission of TRP2 SBFD time units, and the second set of power control parameters corresponds to the corresponding uplink transmission of TRP2 non-SBFD time units.

[0371] In some embodiments, if the correspondence is determined based on signaling indication, the indication signaling includes one or more of RRC, MAC CE or DCI, and the indication state includes one or more of the above, which will not be described herein.
