Sounding reference signal configuration method, terminal and network-side device

A network-side device, comprising a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, cause the network-side device to perform:

• indicating a configuration parameter of a target sounding reference signal (SRS) to a terminal;
• wherein
• in a case that an SRS resource indicated by the configuration parameter comprises N orthogonal frequency division multiplex (OFDM) symbols and the configuration parameter indicates that frequency hopping of the target SRS is disabled, the configuration parameter indicates the terminal to use at least one spatial beam to transmit the target SRS on the N OFDM symbols, wherein N is an integer greater than 1;
• wherein
• in a case that a repetition parameter in the configuration parameter is R, the configuration parameter indicates the terminal to use a same spatial beam on each R OFDM symbols of the N OFDM symbols to transmit the target SRS, wherein spatial beams used among respective R OFDM symbols of the N OFDM symbols are different, and R is an integer greater than 0 and less than or equal to N;
• or,
• in a case that a repetition parameter in the configuration parameter is configured to be on, the configuration parameter indicates the terminal to use a same spatial beam on the N OFDM symbols to transmit the target SRS;
• or in a case that a repetition parameter in the configuration parameter is configured to be off, the configuration parameter indicates the terminal to use a different spatial beam on each OFDM symbol of the N OFDM symbols to transmit the target SRS.

A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, cause the terminal to perform:

• receiving a configuration parameter of a target sounding reference signal (SRS);
• wherein
• in a case that an SRS resource indicated by the configuration parameter comprises N orthogonal frequency division multiplex (OFDM) symbols and the configuration parameter indicates that frequency hopping of the target SRS is disabled, transmitting the target SRS by using at least one spatial beam on the N OFDM symbols, wherein N is an integer greater than 1;
• wherein the program or instructions, when executed by the processor, cause the terminal to perform:
• in a case that a repetition parameter in the configuration parameter is R, transmitting the target SRS by using a same spatial beam on each R OFDM symbols of the N OFDM symbols, wherein spatial beams used among respective R OFDM symbols of the N OFDM symbols are different, and R is an integer greater than 0 and less than or equal to N;
• or,
• wherein the program or instructions, when executed by the processor, cause the terminal to perform:
• in a case that the repetition parameter in the configuration parameter is configured to be on, transmitting the target SRS by using a same spatial beam on the N OFDM symbols;
• or in a case that the repetition parameter in the configuration parameter is configured to be off, transmitting the target SRS by using a different spatial beam on each OFDM symbol of the N OFDM symbols.
