A communication system incorporates a multiplexing scheme so that a base node that schedules user equipment (UE) can determine whether an ACK/NACK and/or a service request (SR) has been re-ceived when both uplink (UL) transmissions are simulta-neously scheduled. Significant complexity reduction, bet-ter link efficiency, and higher multiplexing capability since the base node can interpret selective use by the UE of ei-ther the ACK/NACK or SR UL channel. Such interpreta-tion can be extended to when multiple downlink (DL) transmission modes can be used, specifically DL single in-put multiple output (SIMO), DL multiple input multiple output (MIMO) with rank 1 transmission, and DL MIMO with rank 2 transmission. Based upon knowledge of the scheduling and DL transmission mode, the base node does not have to blind decode a number of possibilities due to the mapping of possible responses from the UE. In addi-tion, the multiplexing scheme is applicable to FDD and TDD. |
