Method for Efficient Control Signaling of Two Codeword to One Codeword Transmission

摘要

In a wireless communication system, a compact control signaling scheme is provided for signaling the selected retransmission mode and codeword identifier for a codeword retransmission when one of a plurality of codewords being transmitted over two codeword pipes to a receiver fails the transmission and when the base station/transmitter switches from a higher order channel rank to a lower order channel rank, either by including one or more additional signaling bits in the control signal to identify the retransmitted codeword, or by re-using existing control signal information in a way that can be recognized by the subscriber station/receiver to identify the retransmitted codeword. With the compact control signal, the receiver is able to determine which codeword is being retransmitted and to determine the corresponding time-frequency resource allocation for the retransmitted codeword.

1. A computer-program storage apparatus comprising a memory having one or more software modules stored thereon, the one or more software modules being executable by one or more processors and the one or more software modules comprising:
code for receiving a first transport block under control of a first control signal; code for storing at least a portion of the first control signal; code for detecting a transmission failure for at least the first transport block; code for sending a request to retransmit the first transport block; code for receiving a second control signal configured to schedule retransmission of the first transport block; and code for receiving the retransmitted first transport block based at least in part on the second control signal and the stored at least portion of the first control signal.
