[0180] The first indication field is related to both the first SRS resource set and the second SRS resource set, and the second indication field is related to the second SRS resource set.

[0181] In an implementation manner of the present application, the first indication field is related to both the first SRS resource set and the second SRS resource set, including:

[0182] The first indication field is used to indicate precoding related information related to both the first port and the second port;

[0186] The second indication field is used to indicate precoding related information corresponding to the SRS resources of the second SRS resource set, such as TPMI.

[0187] In an implementation manner of the present application, the number of precoding layers indicated by the first indication field is the same as the number of precoding layers indicated by the second indication field.

[0188] In an implementation manner of the present application, the first indication domain is a first TPMI domain, and the second indication domain is a second TPMI domain; alternatively, the first indication domain is a predefined domain, and the second indication domain is a TPMI domain.

[0189] In an implementation manner of the present application, the DCI includes a TPMI field, and the TPMI field is related to the first SRS resource set and the second SRS resource set.

[0190] In one implementation of the present application, the TPMI domain is related to the first SRS resource set and the second SRS resource set, including:

[0191] The TPMI field is used to indicate the TPMI corresponding to the SRS resources of the second SRS resource set related to the second SRI field, and precoding related information related to both the third port and the fourth port;

[0192] The third port is an antenna port of an SRS resource of the first SRS resource set, or an antenna port of an SRS resource of the first SRS resource set indicated by the first SRI domain;

[0193] The fourth port is any antenna port of the SRS resources of the second SRS resource set, or any antenna port of the SRS resources of the second SRS resource set indicated by the second SRI domain.

[0194] In an implementation manner of the present application, the first indication field and the second indication field correspond to a 2-antenna codebook.

[0195] In one implementation of the present application, the TPMI field corresponds to a 2-antenna codebook.

[0196] Optionally, the 2-antenna codebook is a 2-antenna codebook in an existing NR protocol;

[0197] or,

[0198] The 2-antenna codebook is in n∈={0,1,...,O*3-1},a is a preset value,O=1 or 2.

[0199] In one implementation manner of the present application, the DCI includes a TPMI field, and the TPMI field is related to the second SRS resource set;

[0200] The TPMI field is used to indicate the TPMI corresponding to the first SRS resource, and the first SRS resource is an SRS resource of the second SRS resource set related to the second SRI field.

[0201] In one implementation of the present application, the DCI further includes an SRS resource set indicator, where the SRS resource set indicator is used to indicate one of the following:

[0202] The first SRI domain is related to the first SRS resource set, and the second SRI domain and the TPMI domain are reserved;

[0203] The first SRI field is reserved, and the second SRI field and the TPMI field are associated with the second SRS resource set;

[0204] The first SRI domain is related to the first SRS resource set, and the second SRI domain is related to the TPMI domain and the second SRS resource set, and the uplink is transmitted based on the SDM mode;

[0205] The first SRI domain is related to the first SRS resource set, and the second SRI domain is related to the TPMI domain and the second SRS resource set, and uplink transmission is performed based on the SFN mode.

[0206] In an implementation manner of the present application, when uplink transmission is performed based on the SFN mode, the TPMI field only indicates a single stream codebook.

[0207] In one implementation of the present application, when the uplink is transmitted based on the SFN mode and the terminal is configured with a maximum of 2 streams for transmission, the size of the TPMI field is calculated according to the single stream codebook indicated by the TPMI field;

[0208] In an implementation manner of the present application, when uplink transmission is performed based on the SFN mode and the terminal is configured with a maximum of 3-stream transmission, the size of the TPMI field is calculated according to the single-stream codebook and the dual-stream codebook indicated by the TPMI field.

[0209] In an embodiment of the present application, a terminal receives first information sent by a network side device, and the first information is used to configure multiple codebook-based SRS resource sets for the terminal, and the multiple codebook-based SRS resource sets include at least a first SRS resource set and a second SRS resource set. The first SRS resource set includes at least one single-port SRS resource, and the second SRS resource set includes at least one multi-port SRS resource, so that the terminal can support uplink transmission of multiple antennas (for example, 3TX), thereby improving the uplink transmission rate and spectrum efficiency of the terminal.

[0210] Taking the uplink multi-panel transmission mode to support uplink 3Tx transmission as an example, different panels support different numbers of uplink transmission antennas and are less than 3Tx, and 2 panels support a total of 3 uplink transmission antennas. For example, uplink 3Tx transmission can be supported by Panel-1(1Tx)+Panel-2(2Tx) or Panel-1(2Tx)+Panel-1(1Tx).

[0211] The capabilities supported by the terminal include: the terminal supports 3Tx full and partial and non-coherent (fullyAndPartialAndNonCoherent) capability, the terminal supports 3Tx non-coherent capability (nonCoherent) and the terminal supports 3Tx partial and non-coherent (partialAndNonCoherent) capability. The UE can report its own capabilities, for example,

[0212] UE reports its support for 3Tx full, partial and incoherent capabilities: such as supporting 3Tx full, partial and incoherent transmission, or supporting 3Tx full, partial and incoherent codebook subsets, or supporting full, partial and incoherent between different panels and full, partial and incoherent between multiple Txs within each panel;

[0213] Alternatively, the UE reports that it supports 3Tx incoherent capability: for example, it supports 3Tx incoherent transmission, or supports 3Tx incoherent codebook subset, or supports incoherence between different panels and incoherence between multiple Txs within each panel;

[0214] Alternatively, the UE reports that it supports 3Tx partial and incoherent capabilities: such as supporting 3Tx partial and incoherent transmission, or supporting 3Tx partial and incoherent codebook subsets, or supporting incoherence between different panels but partial coherence between multiple Txs within each panel.

[0215] The following takes Panel-1 (1Tx) + Panel-2 (2Tx) as an example. It should be noted that the implementation method of Panel-1 (2Tx) + Panel-2 (1Tx) is similar to this.

[0216] Embodiment 1: for a terminal with 3Tx correlation capability, codebook-based coherent transmission.

[0217] Optionally, the higher layer configures two codebook-based SRS resource sets for the UE, where one SRS resource set 1 (SRS resource set-1) includes one or more 1-port SRS resources (1-port SRS resource) (corresponding to Panel-1), and the other SRS resource set 2 (SRS resourceset-2) includes one or more 2-port SRS resources (2-port SRS resource) (corresponding to Panel-2).

[0218] Optionally, 0, 1, or 2 SRIs are indicated in the DCI:

[0219] (1) When SRS resource set-1 includes a 1-port SRS resource and SRS resource set-2 includes a 2-port SRS resource, the SRI field is not indicated in the DCI.

[0220] (2) When SRS resource set-1 includes one 1-port SRS resource and SRS resource set-2 includes multiple 2-port SRS resources, one SRI field is indicated in the DCI (or two SRI fields are indicated, but only one of the SRI fields is valid), and the SRI field is associated with SRS resource set-2;

[0221] (3) When SRS resource set-1 includes multiple 1-port SRS resources and SRS resource set-2 includes multiple 2-port SRS resources, two SRI fields (SRI-1 and SRI-2) are indicated in the DCI, and SRI-1 is associated with SRS resource set-1, and SRI-2 is associated with SRS resource set-2.

[0222] Optionally, two Transmit Precoding Matrix Indicator (TPMI) fields (TPMI-1 and TPMI-2) are indicated in the DCI. The TPMI-1field is used to indicate the precoding (or phase difference, or other precoding-related information) between the antenna port of Panel-1 (i.e., the antenna port of the SRS resource of SRS resource set-1, or the antenna port of the SRS resource of SRS resource set-1 indicated by SRI-1) and the first antenna port of Panel-2 (i.e., the first antenna port of the SRS resource of SRS resource set-2, or the first antenna port of the SRS resource of SRS resource set-2 indicated by SRI-2). The TPMI-2field is associated with SRSresource set-2, and is used to indicate the TPMI (precoding) corresponding to the SRS resource of SRS resource set-2. The number of precoding layers indicated by TPMI-1 is the same as the number of precoding layers indicated by TPMI-2;

[0223] Alternatively, the DCI indicates one TPMI field and one newly defined field (for example, new field). The newfield is used to indicate the precoding (or phase difference, or other precoding-related information) between the antenna port of Panel-1 (i.e., the antenna port of the SRS resource of SRS resource set-1, or the antenna port of the SRS resource of SRS resource set-1 indicated by SRI-1) and the first antenna port of Panel-2 (i.e., the first antenna port of the SRS resource of SRS resource set-2, or the first antenna port of the SRS resource of SRSresource set-2 indicated by SRI-2). The TPMI field is associated with SRS resource set-2, and is used to indicate the TPMI corresponding to the SRS resource of SRS resource set-2. The number of precoding layers indicated by the new field is the same as the number of precoding layers indicated by the TPMI.

[0224] The 2-antenna port codebook corresponding to the above-mentioned TPMI or precoding may be a 2-antenna codebook in the existing NR protocol.

[0225] Example 1-1: Single stream transmission, TPMI-1 indication TPMI-2 indication Then the single-stream codebook corresponding to 3Tx (the port order is: 1-port of Panel-1, the first port of Panel-2, the second port of Panel-2) is

[0239] Optionally, a TPMI field is indicated in the DCI. The TPMI is used as the TPMI (precoding) corresponding to the SRS resource of the SRS resourceset-2 indicated by SRI-2, and is also used as the precoding (or phase difference, or other precoding-related information) between the antenna port of Panel-1 (i.e., the antenna port of the SRS resource of the SRS resourceset-1, or the antenna port of the SRS resource of the SRS resource set-1 indicated by SRI-1) and the first antenna port of Panel-2 (i.e., the first antenna port of the SRS resource of the SRS resource set-2, or the first antenna port of the SRS resource of the SRS resource set-2 indicated by SRI-2), and the two are the same.

[0240] Optionally, the 2-antenna port codebook corresponding to the TPMI or precoding may be a 2-antenna codebook in the existing NR protocol.

[0243] Example 2-3: Dual-stream transmission, TPMI indication Then the dual-stream codebook corresponding to 3Tx (the port order is: 1-port of Panel-1, the first port of Panel-2, the second port of Panel-2) is

[0244] Optionally, the 2-antenna port codebook indicated by the TPMI may also be a newly designed 2-antenna codebook. A newly designed 2-antenna codebook is as follows:

[0245] in n∈={0,1,…,O*3-1}, O=1 or 2, a is a preset value.

[0249] Optionally, the higher layer configures two Codebook-based SRS resource sets for the UE, where one SRSresource set-1 contains one or more 1-port SRS resources (corresponding to Panel-1), and the other SRSresource set-2 contains one or more 2-port SRS resources (corresponding to Panel-2).

One implementation method is:

[0259] (1) SRS resource set indicator = 00, indicating that only Panel-1 transmission is used. At this time, the SRI field and TPMI field information in the DCI are invalid;
