Method and apparatus for supporting communication via a relay wireless device

A wireless device comprising:

• a transceiver;
• and
• a processor operatively coupled to the transceiver;
• wherein:
• the transceiver and the processor are configured to transmit a first buffer status report (BSR) and a second BSR in a medium access control (MAC) protocol data unit (PDU) to a first base station, wherein the first BSR is associated with first data for transmission to the wireless device from at least one wireless transmit/receive unit (WTRU), and the second BSR is associated with second data for transmission to the first base station from the wireless device;
• the transceiver is configured to receive at least a portion of the first data from the at least one WTRU;
• and
• the transceiver and the processor are configured to transmit at least a portion of the second data to the first base station.
