Abstract

Partner relay systems and methods are provided in which relaying is performed by a pair of partner relays. Signals received from a base station are translated by a first of the pair of partner relays to a different transmission resource for communication between the pair of partner relays, and then upon reception by a second of the pair of partner relays, the signal is translated back to the original transmission resource and re-transmitted towards the receiver.

A relay for use with a partner relay in a wireless transmission system, the wireless transmission system comprising at least one base station transceiver and at least one mobile station transceiver and having a first set of transmission resources allocated for forward link transmissions from the at least one base station to the at least one mobile station and a second set of transmission resources allocated for reverse link transmissions from at least one mobile station to the base station to the at least one base station, the relay comprising:
