Abstract
An exemplary method for signaling scheduling information includes scheduling first and second transport blocks for simultaneous transmission during a first transmission interval on first and second data substreams, respectively, assigning a single re-transmission process identifier for the first transmission interval, and transmitting first scheduling information for the first transmission interval. The first scheduling information includes the re-transmission process identifier and first disambiguation data.The method further comprises scheduling at least one of the first and second transport blocks for re-transmission during a second transmission interval and transmitting second scheduling information for the second transmission interval, the second scheduling information including 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 is scheduled for the first or second data substream and may be used by a receiver to determine the same.
