Methods, devices and computer storage media for communication

A method of communication performed by a network device, comprising:

• transmitting, to a terminal device, a downlink control information (DCI) scheduling a Physical Uplink Shared Channel (PUSCH), wherein the DCI comprises
• a first field indicating one or both of a first sounding reference signal (SRS) resource set and
• a second SRS resource set are used for transmission of the PUSCH;
• and
• receiving, from the terminal device, the PUSCH based on a parameter defining the maximum number of layers applied for the first SRS resource set and the second SRS resource set in a case where the first field indicates the first SRS resource set is used for transmission of a first subset of the PUSCH and the second SRS resource set is used for transmission of a second subset of the PUSCH, the value range of the maximum number is {1, 2}.

A terminal device, comprising:

• a processor configured to cause the terminal device to:
• receive, from a network device, a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH), wherein the DCI comprises a first field indicating one or both of a first sounding reference signal (SRS) resource set and a second SRS resource set are used for transmission of the PUSCH;
• and
• transmit, to the network device, the PUSCH based on a parameter defining the maximum number of layers applied for the first SRS resource set and the second SRS resource set in a case where the first field indicates the first SRS resource set is used for transmission of a first subset of the PUSCH and the second SRS resource set is used for transmission of a second subset of the PUSCH, the value range of the maximum number is {1, 2}.
