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.
