Patent ID: 8854944

Claim:
A method for interference cancellation in a wireless device, the method comprising: determining at least one cancellation signal based on signaling received in the wireless device; and canceling interference that is caused to a desired signal by at least one received interfering signal from one of a first quasi orthogonal function (QOF) set and a non-intended base station outside an active set of the wireless device based on the determined at least one cancellation signal, wherein said canceling cancels one of: interference that is caused to a desired signal from a base station within said active set by an interfering signal from the non-intended base station; and interference that is caused to a desired signal from a second QOF set by an interfering signal from the first QOF set, and wherein the second QOF set is non-orthogonal to the first QOF set; wherein the at least one cancellation signal is determined using at least one quasi-linear interference cancellation (QLIC) operation; wherein said determining includes determining at least one further cancellation signal, based on said signaling, and also using said at least one QLIC operation; and wherein said canceling includes canceling interference that is caused to a desired signal from the second QOF set by an interfering signal from the second QOF set based on said at least one further cancellation signal.
