1. A method of providing downlink (DL) retransmissions to a mobile station in a wireless communication network, said wireless communication network comprising a base station communicatively linked to a transparent relay station, said method comprising:
at said base station:
receiving a request for a retransmission from said mobile station;scheduling resources for said retransmission;signaling, using a physical downlink control channel (PDCCH) in a long term evolution (LTE) network or an LTE advanced (LTE-A) network, scheduling information for said retransmission to said transparent relay station via a control link on a first frequency band using a first format, wherein the first format is different from a second format used for signaling scheduling information to a mobile station; at said transparent relay station:
receiving, at said transparent relay station, said scheduling information for said retransmission on said control link during a subframe in the first frequency band; andin response to receiving said scheduling information in the subframe, sending, using a physical downlink shared channel (PDSCH) in the LTE network or the LTE-A network, said retransmission from said transparent relay station to said mobile station in the subframe on a retransmit frequency band, wherein the retransmit frequency band is different from the first frequency band. |
