Abstract:
1. A method for transmitting uplink data by a user agent, comprising: establishing an uplink access link with a relay node that has a relay link to an access device, wherein the uplink access link utilizes an orthogonal frequency-division multiplexing (OFDM) access scheme between the user agent and the relay node regardless of the access scheme used between the relay node and the access device; and transmitting OFDM physical layer feedback to the relay node via the uplink access link, wherein the uplink access link is established using layer 1 signaling, and wherein the relay link is established using higher layer signaling, the higher layer signaling being higher than layer 1 signaling, wherein feedback information is transported more frequently to the relay node via the uplink access link as compared to feedback information transported to the access device via the relay link, wherein the feedback information transported to the relay node comprises the OFDM physical layer feedback.
