Abstract

A dynamic frequency translating repeater operating in a mobile communications system is operable to receive a multi-user signal and perform time-varying and user-specific frequency shifting in the repeater signal. The dynamic frequency translating repeater may further perform user subcarrier specific dynamic frequency translation. Different mobile stations may be allocated different frequency shift amounts based on the interference environments, resource allocations, and scheduling constraints particular to each mobile station.
