Method and user equipment for transmitting uplink signal, and method and base station for receiving uplink signal

摘要

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.

1. A method for receiving, at a base station, an uplink signal from a user equipment having N (N being an integer greater than 1) transmission antennas, the method comprising:
transmitting reception capability information of the base station to the user equipment, the reception capability information including information indicating that the base station may receive a signal transmitted through a maximum of M transmission antennas, where M is an integer greater than 1; and configuring at least one of a first receiver for receiving the uplink signal transmitted through one transmission antenna, a second receiver for receiving the uplink signal transmitted through two transmission antennas, . . . , and an M-th receiver for receiving the uplink signal through M transmission antennas.
