Abstract  Abstract

The invention claims a method and device for space multiplexing in a wireless communication system signalling scheduling information and for processing the signalling information of the method and device. For generating a notification scheduling information for an exemplary method comprises scheduling (310 420) the first and second transport blocks (100) for the first transmission interval on first and second data sub-stream at the same time and further comprising a transmission intervals (320 430) a single re-transmission process identifier and transmitting the first scheduling information 330 440) a first transmission interval. The first scheduling information comprising re-transmission process identifier and first disambiguation data. The method further comprises: scheduling (360 470) the first and second transport blocks (110) at least one of a second transmission interval and transmitting second scheduling information 370 495) a second transmission interval the second scheduling information comprises the re-transmission process identifier and second disambiguation data. The first and second disambiguation data indicate the transmission block of the first or the second data sub-stream scheduling (110) and by the receiver for determining the transmission block of the first or the second data sub-stream scheduling repeat (110).

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
