1. A method for transmitting an aperiodic sounding reference signal (SRS), comprising:
receiving, by a terminal device, a first control instruction for triggering the terminal device to transmit the aperiodic SRS, the first control instruction containing a first parameter field and SRS resource set information, the first parameter field containing a first slot offset; and
determining, by the terminal device, a time-domain location for transmitting the aperiodic SRS according to the first slot offset, and transmitting the aperiodic SRS according to the time-domain location determined,
wherein
the SRS resource set information contained in the first control instruction comprises multiple pieces of third SRS resource set information each corresponding to one of a plurality of third SRS resource sets,
determining, by the terminal device, the time-domain location for transmitting the aperiodic SRS according to the first slot offset, and transmitting the aperiodic SRS according to the time-domain location determined comprise:
determining, by the terminal device, a specified third SRS resource set from the plurality of third SRS resource sets; and
determining, by the terminal device, a third time-domain location according to the first slot offset, and transmitting the aperiodic SRS according to the third time-domain location based on the specified third SRS resource set, and
the method further comprises:
for each of the plurality of third SRS resource sets other than the specified third SRS resource set:
obtaining, by the terminal device, a RRC-configured slot offset corresponding to the third SRS resource set according to the third SRS resource set information;
determining, by the terminal device, a fourth time-domain location corresponding to the third SRS resource set according to the RRC-configured slot offset corresponding to the third SRS resource set; and
transmitting, by the terminal device, the aperiodic SRS according to the fourth time-domain location based on the third SRS resource set.
