HARQ IN SPATIAL MULTIPLEXING MIMO SYSTEM.

Abstract

Methods and apparatus for signaling scheduling information in a spatial multiplexing wireless communications system (700) as well as corresponding methods and apparatus for processing such signaling information are disclosed. An exemplary method for signaling scheduling information comprises scheduling (310 420) first and second transport blocks (110) for simultaneous transmission during a first transmission interval on first and second data substreams respectively and further comprises assigning (320 430) a single re-transmission process identifier for the first transmission interval and transm tt ng(330 440)first scheduling information for the first transmission interval. The first scheduling information comprises the re-transmission process identifier and first disambiguation data. The method further comprises scheduling (360 470)at least one of the first and second transport blocks (110) for re-transmission during a second transmission interval and transmitting (370 495 ) second scheduling information for the second transmission interval the second scheduling information comprising the re-transmission process identifier and second disambiguation data. The first and second disambiguation data indicate whether the re-transmission of the retransmitted transport block (110) is scheduled for the first or second data substream and may be used by a receiver to determine the same.
