The PUSCH supports codebook-based transmission and non-codebook-based transmission, and the following description is made in detail with respect to a codebook-based multi-beam transmission PUSCH and a non-codebook-based multi-beam transmission PUSCH, respectively.

In a first aspect, PUSCH is transmitted based on multiple beams of a codebook.

In the embodiment of the present invention, the DCI includes precoding information and a layer number indication field, where the precoding information and the layer number indication field are used to indicate a precoding codebook corresponding to each piece of spatial correlation information in the plurality of pieces of spatial correlation information.

For example, the network side device configures an SRS resource set 0 for the terminal device through RRC signaling, where the SRS resource set 0 includes 1 SRS resource: SRS resource 0, SRS resource 0 includes 2 pieces of spatial correlation information: first spatial correlation information (identification of SSB 0) and second spatial correlation information (identification of SSB 1).

And the terminal equipment receives the DCI which is transmitted by the network side equipment and used for instructing the terminal equipment to transmit PUSCH1 and PUSCH 2.

The DCI includes an SRS resource indication field, and a field value of the SRS resource indication field is used to indicate a target SRS resource set to the terminal device: SRS resource set 0, i.e. two pieces of spatially related information are indicated to the terminal device: first spatial correlation information (identification of SSB 0) and second spatial correlation information (identification of SSB 1).

The DCI also includes a precoding information and layer number indication field, where the precoding information and layer number indication field are used to indicate: the precoding codebook corresponding to the first spatial correlation information is a first precoding codebook

And the precoding codebook corresponding to the second space-related information is a second precoding codebook

The corresponding DMRS antenna port set is { DMRS antenna port 1, DMRS antenna port 3}, and belongs to the DMRS antenna port group 1.
