Title:
METHOD AND APPARATUS FOR MULTIPLE ACCESS
Document Type and Number:
WIPO Patent Application WO/2021/112602
Kind Code:
A1
Abstract:
According to an embodiment of the present disclosure, a method for performing wireless communication by a UE in a first cell is provided. The method may include: 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 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.
