Patent ID: 8873602

Claim:
A method for transmitting a sounding reference signal (SRS) in a multi-antenna system, comprising: acquiring antenna grouping information; grouping antennas into antenna groups according to said antenna grouping information; acquiring, for each respective antenna group, frequency hopping rule information of the antenna group, wherein the frequency hopping rule information of each antenna group includes a standard frequency hopping rule, a specified level of a tree-node, and a branch offset value at the specified level of the tree-node; determining, for each respective antenna group, frequency hopping rules of the antenna group according to the respective frequency hopping rule information of the antenna group; and transmitting, based on the respective frequency hopping rules, the SRS on the respective antennas of the antenna groups, wherein different antenna groups transmit the SRS in different frequency bands at a same moment, wherein each frequency band of the different frequency bands includes physical resource blocks (PRBs) corresponding to the frequency band.
