Patent ID: 8619940

Claim:
A method for transmitting sounding reference signals at a user equipment in a MIMO antenna wireless communication system, the method comprising: transmitting the sounding reference signals to a base station through a plurality of antenna ports based on parameters for the sounding reference signals given by a higher layer, the parameters including an initial cyclic shift value and an initial transmissionComb value, wherein, when the number of the plurality of antenna ports is 4, a transmissionComb value for each of the plurality of antenna ports is determined in accordance with the following Table: TABLE Transmission comb value Antenna Antenna Antenna Antenna n SRS cs port = 0 port = 1 port = 2 port = 3 0 A A A A 1 A A A A 2 A A A A 3 A A A A 4 A 1-A A 1-A 5 A 1-A A 1-A 6 A 1-A A 1-A 7 A 1-A A 1-A wherein the n SRS cs is the initial cyclic shift value, and the A is the initial transmissionComb value.
