Rank augmentation by wireless relay

Abstract

a method for a User Equipment (UE) to receive data is provided. The method comprises receiving an indication indicating the UE to receive a first RF signal carrying L layers of data on a first time-frequency resource occupying a first bandwidth, wherein L is a positive integer, and to receive K second RF signals each carrying the L layers of data respectively on K sets of non-overlapped second time-frequency resources occupying at least K times the first bandwidth, wherein K is a positive integer greater than 1; receiving, based on the indication, the first RF signal at one or more first receiving antennas on the first time-frequency resource and the K second RF signals at one or more second receiving antennas respectively on the K sets of non-overlapped second time-frequency resources; obtaining a first baseband signal from the first RF signal and K second baseband signals from the K second RF signals; and determining the L layers of data based on the first baseband signal and the K second baseband signals.
