Abstract: Embodiments of the present invention disclose a sounding reference symbol SRS transmission method and a radio remote unit. The method, performed by a radio remote unit, includes: receiving a plurality of pieces of sampled data in a first period by using each antenna of an antenna array; if all of the plurality of pieces of sampled data are the SRS sampled data, buffering the plurality of pieces of sampled data; and reading the plurality of pieces of sampled data from the buffer in a second period, and sending the read plurality of pieces of sampled data to a baseband processing unit, where duration of the second period is longer than duration of the first period. Thus according the embodiments of the present invention, a time for transmitting the SRS sampled data is prolonged, so that bandwidth required for transmitting the SRS sampled data can be reduced.
