METHOD AND DEVICE FOR TRANSMITTING SOUNDING REFERENCE SIGNAL
摘要
<p>A method and device for transmitting sounding reference signal (SRS). The method includes that: in at least two cells which need a user equipment (UE) to perform uplink channel sounding, the SRS resources for performing sounding to each cell are distributed to the UE; the UE is indicated to transmit the SRS on the distributed SRS resources. The method of the present invention can enable the UE to detect the channels of a plurality of cells and to be used in multipoint cooperative transmission, avoid the UE feeding back the channel information of a plurality of cells, and reduce the feedback overhead and improve the system performance.</p>
