DEMODULATION REFERENCE SIGNALS (DM-RS) FOR PHICH OR PDCCH BASED RETRANSMISSION IN LTE-A WIRELESS COMMUNICATION |
摘要 |
Provided is a method for wireless communication which includes transmitting codewords according to an initial transmission rank, receiving downlink transmissions indicating at least one of the codewords to be retransmitted, constructing a demodulation reference signal (DM-RS) to be sent with the at least one codeword to be retransmitted, and retransmitting the at least one codeword with the DM-RS according to a retransmission rank. The downlink transmissions may include one or more physical hybrid automatic retransmission request indicator channels and the DM-RS may be constructed based at least in part on information in the downlink transmissions. |
