Abstract
The embodiments of the present invention disclose a method, device and system for transmitting Sounding Reference Signals (SRSs). The method includes the following steps: a user equipment receives the special SRS sequence information for Coordinated Multi-Point Operation (CoMP) from a base station equipment, and the base station equipment corresponds to a cell in a CoMP SRS cluster (101); the user equipment transmits an SRS to the cell in the CoMP SRS cluster based on the special SRS sequence information for CoMP (102). The embodiments of the present invention ensure the accuracy and reliability of channel estimation.
Claims27
