Patent ID: 8428166

Claim:
A method for transmitting a sounding reference signal at a user equipment in a MIMO antenna wireless communication system, the method comprising: receiving parameters for the sounding reference signal from a base station, the parameters including an initial cyclic shift value and an initial transmissionComb value; configuring cyclic shift values corresponding to a plurality of antenna ports based on the initial cyclic shift value; configuring transmissionComb values corresponding to the plurality of antenna ports based on the initial transmissionComb value; and transmitting the sounding reference signal to the base station through each of the plurality of antenna ports by using the configured cyclic shift values and transmissionComb values, wherein, if the initial cyclic shift value is a predetermined value and the number of the plurality of antenna ports is 4, the transmissionComb values corresponding to two antenna ports of the plurality of antenna ports are configured as 1 minus the initial transmissionComb value.
