Abstract
A method for transmitting, at a user equipment having N (N being an integer greater than 1) transmission antennas, an uplink signal to a base station and a method for receiving, at the base station, an uplink signal from the user equipment are disclosed. The base station transmits reception capability information of the base station to the user equipment. Reception capability information includes information indicating that the base station may receive a signal transmitted through a maximum of M (M being an integer greater than 1) transmission antennas. The user equipment transmits the uplink signal using N transmission antennas if N is not greater than M and transmits the uplink signal using M transmission antennas if N is greater than M.
