Abstract:
1. A method for transmitting a Sounding Reference Signal (SRS) to a base station at a User Equipment (UE) using a plurality of antennas on a plurality of carriers in a mobile wireless communication system, the method comprising: receiving a cyclic shift value for a first antenna via a higher layer; configuring a cyclic shift value for a second antenna by using the cyclic shift value for the first antenna; generating a first SRS sequence using the cyclic shift value for the first antenna and a second SRS sequence using the cyclic shift value for the second antenna, wherein the first SRS sequence and the second SRS sequence are generated from a same base sequence; transmitting, at a first transmission timing, the first SRS sequence through the first antenna on a first carrier and the second SRS sequence through the second antenna on a second carrier; and transmitting, at a second transmission timing, the first SRS sequence through the first antenna on the second carrier and the second SRS sequence through the second antenna on the first carrier, wherein the first SRS sequence and the second SRS sequence have a same hopping pattern.
