1. A method for performing wireless communication by a user equipment (UE) in a first cell, the method including:
obtaining first N streams based on precoding of a transmit symbol vector obtained based on N data symbols; and
transmitting the first N streams to an access point (AP) based on first M antennas,
wherein the first N streams are received by the AP included in the first cell based on second M antennas,
wherein the precoding is performed based on a cross-channel from the UE to a second cell which is different from the first cell, and
wherein the N is equal to half of the M, and the M and the N are positive integers.
