Method and apparatus for use in cooperative relays using incremental redundancy and distributed spatial multiplexing
Abstract
A method and apparatus may be used in cooperative relays with incremental redundancy (IR) and distributed spatial multiplexing. A wireless transmit/receive unit (WTRU) may listen to the base station (BS) transmission during a first phase of the communication, and use cooperation between a relay station (RS) and the BS for the data transmission during a second phase to improve performance. During the second phase, both the BS and the RS may transmit data to the WTRU, using either distributed Space Time Block Codes/Space Frequency Block Codes (STBC/SFBC) or distributed spatial multiplexing.
