Abstract
The method for transmitting an uplink SRS by an LTE UE comprising steps of: the UE receiving information N indicating SRS transmission; generating an SRS sequence by the UE; and the UE transmitting the SRS in two OFDM symbol in a half-frame or frame if the information N indicates that a period of SRS transmission is 2 ms. With present invention, a format of SRS in LTE FDD and LTE TDD will be the same. Meanwhile, a problem of supporting 2 ms period in the LTE TDD system is solved.
