Abstract
Briefly, in accordance with one or more embodiments in a wireless network, a station may overhear one or more packets that are not necessarily destined for those stations. The overhearing station may decode the data of the packet, and may utilizes the decoded packet to remove a retransmission of that packet in a subsequent time slot and occurring at the same time as the transmission of a packet destined for that station in the same time slot. Such a retransmission of packets may occur for example in relay systems and/or in hybrid automatic repeat request (HARQ) systems. The retransmitted packet may be treated as an interference signal in the total received signal, so that the previously received and decoded packet may be subtracted from the total signal, allowing the desired packet to be decoded from the intended signal.
