Claim 7:
8. A method for a first wireless transmit/receive unit (WTRU), comprising:
triggering a first buffer status report (BSR), wherein the first BSR indicates an amount of data expected to arrive from a third WTRU to the first WTRU for uplink transmission to a second WTRU;
triggering a second BSR, wherein the second BSR indicates an amount of data already available at the first WTRU for uplink transmission to the second WTRU;
determining whether to include a first BSR Medium Access Control (MAC) Control Element (CE) for the first BSR and/or a second BSR MAC CE for the second BSR into a MAC Protocol Data Unit (PDU) based on at least a rule which prioritizes the second BSR MAC CE over the first BSR MAC CE on the order of inclusion; and
transmitting the MAC PDU using uplink resources allocated by the second WTRU for uplink transmission, wherein
the MAC PDU includes one second BSR MAC CE when the uplink resources are enough to accommodate the second BSR MAC CE but are not enough to accommodate both the first BSR MAC CE and the second BSR MAC CE; and
the MAC PDU includes both the first BSR MAC CE and the second BSR MAC CE when the uplink resources are enough to accommodate both the first BSR MAC CE and the second BSR MAC CE.
