[0050] With reference to the accompanying drawings, the application will be described in more detail below in terms of some embodiments and application scenarios.

[0051] Please refer to Figure 2 , Figure 2 is a flowchart of a transmission parameter determination method provided by the application, as shown in Figure 2 , comprising the following steps:

[0052] Step 201, the terminal receives DCI, the DCI is used to activate a target CG, or the DCI is used to schedule PUSCH of data of the target CG, wherein the target CG includes multiple sets of transmission parameters.

[0053] The above-mentioned DCI is the DCI received by the terminal from the network side device, which is an activation DCI or a scheduling DCI, and is specifically used to activate the above-mentioned target CG, or to schedule PUSCH of data of the target CG. The above-mentioned PUSCH can be a retransmission PUSCH or an initial transmission PUSCH. The above-mentioned retransmission PUSCH can be a PUSCH scheduled by a DCI with CRC scrambled with CS-RNTI and NDI=1, i.e. the DCI is a DCI scheduling retransmission PUSCH of CG.

[0054] In some embodiments, the above-mentioned DCI can be DCI format 0_1, or DCI format 0_2, or other DCI formats, which are not limited.

[0055] The above-mentioned target CG can be one or more CGs explicitly or implicitly indicated by the above-mentioned DCI. For example: the above-mentioned target CG is a CG explicitly or implicitly indicated by the above-mentioned DCI in at least one CG pre-acquired by the terminal, wherein the at least one CG pre-acquired by the terminal can be at least one CG configured by the network side for the terminal before step 201 is performed.

[0056] The above-mentioned target CG includes multiple sets of transmission parameters, which can be that the above-mentioned target CG includes multiple sets of uplink transmission related transmission parameters, and each set of transmission parameters can include at least one transmission parameter in spatial relationship, power control parameter, resource, precoding, number of layers, etc.

[0057] In step 202, the terminal determines the target CG or the target transmission parameter of the PUSCH from the multiple sets of transmission parameters according to the DCI.

[0058] The target transmission parameter can be explicitly or implicitly indicated by the DCI. The target transmission parameter of the target CG or the retransmission PUSCH refers to the transmission parameter used by the terminal in the target CG or the PUSCH.

[0059] In the embodiments, the terminal can determine the target CG or the target transmission parameter of the PUSCH from the multiple sets of transmission parameters, thereby improving the flexibility of the terminal transmission.

[0060] As an optional implementation, any one of the multiple sets of transmission parameters includes at least one of the following:

[0061] a target reception power parameter of the control information on the configured grant (uci-OnPUSCH);

[0062] a closed loop power control adjustment index (powerControlLoopToUse);

[0063] a target reception power and a path loss compensation factor (p0-PUSCH-Alpha);

[0064] a precoding and number of layers (precodingAndNumberOfLayers);

[0065] an SRS resource indication (srs-ResourceIndicator);

[0066] a path loss reference index (pathlossReferenceIndex).

[0067] Any one of the multiple sets of transmission parameters includes the at least one can be understood as that each set of transmission parameters in the multiple sets of transmission parameters can include the at least one, but it is not limited that each set of transmission parameters includes the same type of transmission parameter. For example, one set of transmission parameters includes the six items, and another set of transmission parameters can include only part of the six items, such as the target reception power parameter of the control information on the configured grant and the target reception power and the path loss compensation factor, and the remaining transmission parameters can be configured by other means, or the default parameters are used, etc.

[0068] As an optional implementation, the method further includes:

[0069] The terminal receives a configuration issued by a network side, and the configuration includes at least one of the following:

[0070] an SRS resource set configured for the first DCI format;

[0071] an SRS resource set configured for the second DCI format;

[0072] at least one CG;

[0073] The DCI is the first DCI format or the second DCI format.

[0074] The target CG is a CG in the at least one CG.

[0075] The configuration can be dynamically, statically or semi-statically configured by the network side.

[0076] The SRS resource set configured for the first DCI format can include one or more SRS resource sets, and the SRS resource set configured for the second DCI format can include one or more SRS resource sets.

[0077] Each CG in the at least one CG includes multiple sets of transmission parameters.

[0078] In this embodiment, the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format can support the terminal to send uplink transmission to the network side through the activation or calling of different DCI formats.

[0079] For example, in a multi-transmission-reception-point (multi-TRP, MTRP) scenario, configuring multiple SRS resource sets can mean that uplink transmission can be sent to two TRPs. In order to achieve configuration flexibility, different numbers of SRS resource sets can be configured for different DCI formats to realize that single-TRP and multi-TRP can be scheduled by different DCI formats.

[0080] In some embodiments, the first DCI format can be DCI format 0_1, and the second DCI format can be DCI format 0_2, or the first DCI format can be DCI format 0_2, and the second DCI format can be DCI format 0_1, and the specific implementation is not limited. For example, when the number of SRS resource sets configured by DCI format 0_1 and DCI format 0_2 is different, such as two SRS resource sets configured by DCI format 0_1 and one SRS resource set configured by DCI format 0_2, the configuration of the CG includes two sets of transmission parameters associated with the two SRS resource sets. At this time, if the terminal receives DCI, the format is 0_2, and is used to activate the CG or schedule the retransmission of the CG data, the transmission parameters of the activated CG use the first set of transmission parameters of the two sets of transmission parameters, and the parameters of the retransmission PUSCH of the data of the CG use the second set of transmission parameters of the terminal.

[0081] As an optional embodiment, the multiple sets of transmission parameters are respectively associated with multiple SRS resource sets.

[0082] The multiple SRS resource sets include at least one of the following:

[0083] The SRS resource set configured for the first DCI format;

[0084] The SRS resource set configured for the second DCI format.

[0085] The multiple sets of transmission parameters are respectively associated with multiple SRS resource sets, which can be that one set of transmission parameters corresponds to one SRS resource set.

[0086] The association between the multiple sets of transmission parameters and the multiple SRS resource sets can be preconfigured, or dynamically, statically, or semi-statically configured by the network side.

[0087] In this embodiment, the association between the transmission parameters and the SRS resource sets can be achieved, so that the transmission parameters can be used for CG transmission of the SRS resources of the SRS resource set associated with the transmission parameters, so as to improve the transmission reliability.

[0088] Optionally, in the case that multiple SRS resource sets are configured for the first DCI format, and one SRS resource set is configured for the second DCI format, the one SRS resource set configured for the second DCI format includes N SRS resources in a reference SRS resource set, and the reference SRS resource set is the first SRS resource set in the multiple SRS resource sets configured for the first DCI format; and / or

[0089] In a case that a target SRS resource set is configured for the first DCI format and a plurality of SRS resource sets are configured for the second DCI format, a first SRS resource set configured for the second DCI format includes N SRS resources in the target SRS resource set;

[0090] N is an integer greater than or equal to 1.

[0091] The N SRS resources in the reference SRS resource set can be the first N SRS resources in the reference SRS resource set, where the first N SRS resources can be the first N SRS resources sorted by index or the first N SRS resources sorted by resource. The N SRS resources in the target SRS resource set are the same, and details are not repeated here.

[0092] The target SRS resource set can be understood as the SRS resource set configured for the first DCI format, such as one SRS resource set configured for the first DCI format or the first SRS resource set in the plurality of SRS resource sets configured for the first DCI format.

[0093] In this embodiment, the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format can have some same SRS resources, so as to reduce the number of SRS resources and the transmission complexity of the terminal.

[0094] Optionally, one SRS resource set configured for the second DCI format has some or all of the transmission parameters same as those of the reference SRS resource set; and / or

[0095] The first SRS resource set configured for the second DCI format has some or all of the transmission parameters same as those of the target SRS resource set.

[0096] The transmission parameters can include a power control parameter.

[0097] In this embodiment, the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format can have the same transmission parameters, so as to ensure that the same SRS resources can be transmitted with the same set of parameters.

[0098] For example, two SRS resource sets are configured for the first DCI format and one SRS resource set is configured for the second DCI format, and the one SRS resource set configured for the second DCI format is configured with reference to the first SRS resource set configured for the first DCI format, that is, the first N SRS resources and the power control parameter of the first SRS resource set are included.

[0099] For example, one SRS resource set is configured for the first DCI format, and two SRS resource sets are configured for the second DCI format. The first SRS resource set in the two SRS resource sets configured for the second DCI format refers to the configuration of the one SRS resource set configured for the first DCI format, i.e., the first N SRS resources and the power control parameters in the first SRS resource set.

[0100] Optionally, the one SRS resource set configured for the second DCI format is activated at the same time as the reference SRS resource set; and / or

[0101] The first SRS resource set configured for the second DCI format is activated at the same time as the target SRS resource set.

[0102] The above-mentioned activation at the same time means that when one SRS resource set is activated, the other SRS resource set is also activated at the same time.

[0103] In this embodiment, since the one SRS resource set configured for the second DCI format is activated at the same time as the reference SRS resource set, and the first SRS resource set configured for the second DCI format is activated at the same time as the target SRS resource set, the activation overhead can be saved.

[0104] Optionally, the first SRS resource set in the multiple SRS resource sets configured for the first DCI format comprises the SRS resource with the maximum first SRS port number, and the SRS resource with the maximum first SRS port number is the SRS resource with the maximum SRS port number in the multiple SRS resource sets configured for the first DCI format; and / or

[0105] The first SRS resource set in the multiple SRS resource sets configured for the second DCI format comprises the SRS resource with the maximum second SRS port number, and the SRS resource with the maximum second SRS port number is the SRS resource with the maximum SRS port number in the multiple SRS resource sets configured for the second DCI format.

[0106] In this embodiment, the first SRS resource set can comprise the SRS resource with the maximum SRS port number in the multiple SRS resource sets.

[0107] Optionally, the first SRS resource set in the multiple SRS resource sets configured for the first DCI format refers to the SRS resource set with the minimum SRS resource set index in the multiple SRS resource sets configured for the first DCI format; or in the case of one SRS resource set configured for the first DCI format, the first SRS resource set in the SRS resource set configured for the first DCI format refers to the one SRS resource set configured for the first DCI format; and / or

[0108] The first SRS resource set in the plurality of SRS resource sets configured for the second DCI format refers to an SRS resource set with the smallest SRS resource set index in the plurality of SRS resource sets configured for the second DCI format, or in the case of one SRS resource set configured for the second DCI format, the first SRS resource set in the SRS resource set configured for the second DCI format refers to the one SRS resource set configured for the second DCI format.

[0109] In this embodiment, the first SRS resource set can be determined by the index, or in the case of only one SRS resource set being configured, the first SRS resource set is the one SRS resource set.

[0110] As an optional embodiment, the method further comprises:

[0111] The terminal receives a medium access control control element (MAC CE);

[0112] The terminal determines at least one of the following according to the MAC CE:

[0113] The spatial relationship of the SRS resource in the SRS resource set configured for the first DCI format;

[0114] The spatial relationship of the SRS resource in the SRS resource set configured for the second DCI format.

[0115] The MAC CE is a MAC CE sent by a network side device and received by the terminal.

[0116] The spatial relationship of the SRS resource can refer to a certain signal of a spatial beam referenced when the terminal transmits the SRS.

[0117] The MAC CE can be a MAC CE for activating the SRS resource set, or a MAC CE for indicating the spatial relationship.

[0118] The terminal determining the at least one according to the MAC CE can be updating the at least one according to the MAC CE, i.e., determining the latest spatial relationship, or determining the at least one according to the indication of the MAC CE, i.e., determining the indicated spatial relationship. The updating can be updating according to the spatial relationship information carried by the MAC CE, or updating according to a pre-configured updating rule, which is not limited in particular.

[0119] In this embodiment, the spatial relationship of the SRS resource can be determined in time, so that the resource configuration is more flexible.

[0120] Optionally, the MAC CE comprises at least one of:

[0121] an index of a SRS resource set configured for the first DCI format;

[0122] an index of a SRS resource set configured for the second DCI format.

[0123] In this embodiment, the SRS resource set for which the spatial relation needs to be determined can be indicated by the index.

[0124] It should be noted that the above index is not necessarily included in the MAC CE in the embodiments of the present application. For example, in some embodiments, the SRS resources in all or part of the SRS resource sets can be updated by default, or the MAC CE can implicitly indicate the SRS resource set that needs to be updated.

[0125] Optionally, the spatial relation of the SRS resource with the same index in the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format is determined simultaneously.

[0126] In this embodiment, the spatial relation of the SRS resource with the same index in the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format is determined simultaneously, which can save the MAC CE overhead. For example, when the terminal receives the MAC CE carrying the index of any one of the SRS resource set configured for the first DCI format and the SRS resource set configured for the second DCI format, the MAC CE can simultaneously determine the spatial information of the SRS resource with the same index in the first SRS resource set and the second SRS resource set.

[0127] As an optional embodiment, the DCI comprises a plurality of Transmitted Precoding Matrix Indicator (TPMI) fields, wherein:

[0128] The length of the first TPMI field in the plurality of TPMI fields is determined by the maximum number of SRS ports in the plurality of SRS resource sets configured for the DCI;

[0129] The length of the second TPMI field in the plurality of TPMI fields is determined by the maximum number of ports in a preset SRS resource set in the plurality of SRS resource sets configured for the DCI.

[0130] The plurality of TPMI fields can be 2 or more than 2 TPMI fields.

[0131] The first TPMI domain in the multiple TPMI domains can be a first TPMI domain in the multiple TPMI domains according to an index or a position order. The second TPMI domain in the multiple TPMI domains can be a second TPMI domain in the multiple TPMI domains according to the index or the position order.

[0132] The multiple SRS resource sets configured for the DCI can be multiple SRS resource sets configured for a DCI format of the DCI. For example, the DCI is a first DCI format, and the multiple SRS resource sets refer to multiple SRS resource sets configured for the first DCI format.

[0133] The length of the first TPMI domain determined by the maximum SRS port number in the multiple SRS resource sets configured for the DCI can be that the length of the first TPMI domain matches the maximum SRS port number in the multiple SRS resource sets. The rule of the determination can be agreed by a protocol or configured by a network side.

[0134] The length of the second TPMI domain determined by the maximum port number in a preset SRS resource set in the multiple SRS resource sets configured for the DCI can be that the length of the second TPMI domain matches the maximum port number in the preset SRS resource set in the multiple SRS resource sets configured for the DCI. The rule of the determination can be agreed by a protocol or configured by a network side.

[0135] The preset SRS resource set can be a second SRS resource set in the multiple SRS resource sets. The second SRS resource set in the multiple SRS resource sets can refer to the corresponding description in the above embodiments, which is not repeated here.

[0136] In this embodiment, since the DCI includes multiple TMPI domains, the length of the first TPMI domain is determined by the maximum SRS port number in the multiple SRS resource sets, and the length of the second TPMI domain is determined by the maximum port number in the preset SRS resource set in the multiple SRS resource sets, so that the length of the first TPMI domain in the multiple TMPI domains is sufficient to select a precoding from a codebook corresponding to the maximum port number, thereby improving the flexibility of precoding indication.

[0137] As an optional embodiment, the terminal determines a target CG or a target transmission parameter of the PUSCH from the multiple sets of transmission parameters according to the DCI, including at least one of the following:

[0138] In the case where the DCI includes a target domain, the terminal determines the transmission parameter indicated by the target domain in the multiple sets of transmission parameters as the target CG or the target transmission parameter of the PUSCH.

[0139] In a case that the DCI does not include the target field, a preset transmission parameter in the multiple sets of transmission parameters is determined as the target transmission parameter of the CG or the PUSCH.

[0140] The target field can be a field indicating a transmission parameter.

[0141] The transmission parameter indicated by the target field in the multiple sets of transmission parameters can refer to an indication manner shown in Table 1, and Table 1 is as follows:

[0142] Target domain Parameter determination 00 First set of parameters of CG configuration (associated with first SRS resource set) 01 Second set of parameters of CG configuration (associated with second SRS resource set) 10 Two sets of parameters of CG configuration 11 Two sets of parameters of CG configuration

[0143] The target field can also be a field indicating an SRS resource set. Two sets of parameters of the CG configuration are associated with two SRS resource sets, and the transmission parameter is further indicated by indicating the resource set.

[0144] In the embodiment of Table 1, if the CG configuration contains only one set of parameters, or the CG configuration contains multiple sets of parameters but the DCI activating the CG only indicates that the CG transmission adopts one set of parameters, the first target field is 00.

[0145] According to the target field, the transmission parameter of the CG can be determined, and it can be determined whether the parameter of the PUSCH of the CG adopts multiple sets of transmission parameters or one set of transmission parameters, and the specific transmission parameter of the multiple sets of transmission parameters.

[0146] It should be noted that Table 1 is only an example, and the manner of indicating the transmission parameter by the target field is not limited in the embodiments of the present application.

[0147] The preset transmission parameter is a pre-specified transmission parameter or a transmission parameter determined according to a pre-specified rule. For example, the preset transmission parameter includes the following:

[0148] The first set of transmission parameters in the multiple sets of transmission parameters;

[0149] The transmission parameter associated with the first SRS resource set in the multiple sets of transmission parameters;

[0150] The transmission parameter indicated by the DCI in the multiple sets of transmission parameters.

[0151] The first set of transmission parameters is the first indexed transmission parameter in the multiple sets of transmission parameters, or the first set of transmission parameters determined according to the order of configuration or the order of position in the configuration signaling.

[0152] The first SRS resource set refers to the first SRS resource set in the SRS resource set configured for the DCI format of the DCI.

[0153] Optionally, the method further comprises:

[0154] The terminal determines whether the DCI includes the target field according to the number of SRS resource sets configured for the DCI format of the DCI.

[0155] In this embodiment, it can be implemented that whether the DCI includes the target field is configured according to the number of SRS resource sets configured for the DCI format.

[0156] For example, in the case that the number of SRS resource sets configured for the DCI format of the DCI is a preset number, it is determined that the DCI includes the target field.

[0157] Or, in the case that the number of SRS resource sets configured for the DCI format of the DCI is not a preset number, it is determined that the DCI does not include the target field. Here, not including the target field can also be said that the length of the target field is 0 bits.

[0158] The preset number can be 2, 3, etc.

[0159] It should be noted that in the embodiments of the present application, it can also be directly determined whether the DCI includes the target field according to the DCI format of the DCI. And in the case that the DCI includes the target field, the terminal determines that the target transmission parameter of the target CG or the PUSCH in the multiple sets of transmission parameters is the target transmission parameter, and in the case that the DCI does not include the target field, the terminal determines that the preset transmission parameter in the multiple sets of transmission parameters is the target transmission parameter of the target CG or the PUSCH.

[0160] In the embodiments of the present application, a terminal receives target downlink control information DCI, the DCI is used to activate a target configured grant CG, or the DCI is used to schedule a retransmission physical uplink shared channel PUSCH of data of the target CG, wherein the target CG includes multiple sets of transmission parameters; the terminal determines a target transmission parameter of the target CG or the retransmission PUSCH in the multiple sets of transmission parameters according to the DCI. In this way, the terminal supports the terminal to determine the target transmission parameter of the target CG or the retransmission PUSCH in the multiple sets of transmission parameters, thereby improving the flexibility of terminal transmission.

[0165] The multiple SRI fields described above can indicate different SRS resources.

[0166] Step 302, the terminal determines the SRS resource corresponding to the PUSCH transmission according to the multiple SRI fields.

[0167] The terminal determines the SRS resource corresponding to the PUSCH transmission according to the multiple SRI fields described above can be to determine the SRS resource indicated by each SRI field.

[0168] In the embodiments of the present application, the multiple SRI fields determine the SRS resource corresponding to the PUSCH transmission can be achieved by the above steps, thereby supporting the PUSCH to use the SRS resource indicated by the multiple SRI fields for transmission, so as to improve the reliability of the PUSCH transmission, and to solve the problem of low reliability of the PUSCH transmission.

[0169] Optionally, the multiple SRI fields include a first SRI field and a second SRI field.

[0170] The SRS resource indicated by the first SRI field is the SRS resource closest to the target resource and transmitted before the target resource in the SRS resource set corresponding to the first SRI field.

[0171] The SRS resource indicated by the second SRI field is the SRS resource closest to the target resource and transmitted before the target resource in the SRS resource set corresponding to the second SRI field.

[0172] The target resource is the transmission resource of the DCI.

[0173] The first SRI field and the second SRI field described above can be the first SRI field and the second SRI field in the DCI, wherein the first SRI field and the second SRI field can be determined according to the position order in the DCI.

[0174] For the first SRI field, the target resource can be understood as a physical downlink control channel (PDCCH) resource carrying the DCI of the first SRI field; for the second SRI field, the target resource can be understood as a PDCCH resource carrying the DCI of the second SRI field. Or a PDCCH resource carrying the DCI of the first SRI field and the second SRI field.

[0175] In this embodiment, since the SRS resource indicated by the SRI field is the SRS resource closest to the target resource in the SRS resource set corresponding to the SRI field and is transmitted before the target resource, the terminal can determine the latest SRS resource for PUSCH transmission, thereby improving the reliability of the parameters of the PUSCH transmission.

[0180] The first SRS resource set corresponding to the first SRI field is indicated by 00 / 10 / 11, and the second SRS resource set corresponding to the first SRI field is indicated by 01.

In addition, in some embodiments, the target field in this embodiment can be different from the target field in the embodiment shown in Figure 2 For example, the target field in this embodiment can be 1 bit.

The first SRS resource set and the second SRS resource set can be understood in the manner described in the embodiment shown in Figure 2 The embodiment.

[0183] In this embodiment, only one SRS resource set needs to be indicated in the DCI, thereby saving DCI overhead.

[0184] For example, the terminal receives the DCI, if the DCI contains two SRI fields, the second SRI field corresponds to the SRS resource in the second SRS resource set closest to the target resource, and the first SRI field corresponds to the SRS resource in the target SRS resource set closest to the target resource, the target SRS resource set is the first or second SRS resource set, and the target resource set can be determined by the indication field in the DCI.

[0187] In this embodiment, in the case of corresponding to a plurality of SRS resource sets, the DCI only needs to indicate one SRS resource set, thereby saving DCI overhead.
