Abstract
Disclosed are a method and a device for transmitting an aperiodic SRS in a TDD system. In the technical solution of the present invention, a symbol is defined for the transmission of the aperiodic SRS in a special subframe in the TDD system. This avoids a scenario in which the transmission position of the aperiodic SRS is undefined when a plurality of symbols that can be used to transmit the aperiodic SRS are available in an uplink pilot time slot (UpPTS). The problem of transmitting aperiodic SRS in a TDD system special subframe is thus solved. The modification to corresponding instruction messages is not extensive, and there is no overuse of system resources.
