Abstract:
Historical decoding can be performed in accordance with pilot signal retransmission or control information retransmission to reduce the amount network resources consumed during data recovery. In one example, historical decoding is achieved through retransmitting a sub-set of coded bits carried by an earlier transmission, which are compared with a corresponding portion of the original signal (stored in memory) to obtain improved channel state information (CSI) relating to that earlier transmission. In another example, historical decoding is achieved through communicating parity information related to a sub-set of the coded bits carried by an earlier transmission, which are used in accordance with a data aided CSI technique to obtain the improved CSI relating to that earlier transmission. In yet another example, historical decoding is achieved by re-transmitting control information carried by an earlier transmission.
