Abstract:
1. A method at a base station, the base station being within an active set of base stations with which a mobile terminal in handoff is sending data in a signal, the active set comprising a serving base station and one or more non-serving base stations, the method comprising: receiving a received signal at the serving base station from the mobile terminal and carrying out a decoding operation for the received signal; sending successfully decoded data decoded at the serving base station, and a transmission format of the received signal, to one or more of the non-serving base stations in the active set, the decoded data and the transmission format being sent via a backhaul network interconnecting the base stations of the active set; wherein the transmission format includes a number of retransmissions that were required for the serving base station to successfully decode the data, and the decoded data and the transmission format sent from the serving base station are usable by at least one of the one or more non-serving base stations in the active set to remove, from other signals received at the non-serving base station, interference attributable to transmission of the received signal.
