摘要:
A wireless communication transceiver compensates a given received signal for retransmission interference, if (uncompensated) decoding of the given received signals fails. The transceiver estimates the retransmission interference bearing on the given received signal based on hypothesizing that another user (or users) mistakenly transmitted in the same time interval, using some or all of the same channel resources as were allocated to the given received signal. The transceiver may retain information in any given interval, indicating the channel allocations used for those user signals successfully received in that interval. The retained information allows the transceiver to determine, with respect to a given signal received in a current time interval, which other users would be interfering users if they mistakenly retransmitted in the current time interval. The transceiver may target its compensated decoding, which may be iterative, to the most likely and/or most significant ones of the potentially of interfering user(s).
