Claim Text:
1. A method for subtracting interference in a wireless communications network, the method comprising: receiving a first baseband signal including an interference signal at a first base station; receiving a second baseband signal including the interference signal at a second base station; calculating a channel translation parameter based on the first baseband signal and the second baseband signal; receiving a signal including a user equipment (UE) transmission at the first base station during a first time slot; and subtracting interference from the signal including the UE transmission using the channel translation parameter, wherein subtracting interference from the signal including the UE transmission includes: receiving a signal including a UE transmission at the second base station during the first time slot; decoding the UE transmission received at the second base station; and subtracting the UE transmission from the signal including the UE transmission received by the second base station to create an interference signal, wherein the interference subtracted from the signal received at the first base station is a result of subtracting the UE transmission from the signal including the UE transmission received by the second base station.
