Patent ID: 8917688

Claim:
A method of processing a composite wideband signal received at a local base station, the composite wideband signal including, over one or more frequency groups, at least one local signal associated with at least one locally scheduled user and at least one desired signal associated with at least one desired user scheduled by a neighboring base station, wherein the local base station receives scheduling information for the at least one desired user from the corresponding neighboring base stations, the method comprising: estimating a combined local signal comprising all local signals in the composite wideband signal based on local scheduling information, wherein: the local scheduling information allocates a unique set of local frequencies to each of the at least one locally scheduled user; the received scheduling information allocates a set of desired frequencies to each of the at least one desired user; and at least one of the sets of desired frequencies at least partially overlaps at least one of the sets of local frequencies; subtracting the combined local signal from the composite wideband signal to generate a combined desired signal; and detecting one or more of the desired signals in the composite wideband signal based on desired reference sequences allocated to the one or more desired users as indicated by the received scheduling information.
