Claim Text:
1. A method for uplink transmission implemented at a wireless transmit/receive unit (WTRU), comprising: receiving a message to trigger the WTRU to start the uplink transmission over a resource shared by a group of WTRUs, wherein the WTRU is a member of the group and the message contains a group index indicating a time interval for the group of WTRUs to start the uplink transmission on the resource; determining a transmission time for the WTRU to start the uplink transmission over the resource in response to the message, wherein the transmission time for each WTRU in the group of WTRUs is determined based on a unique identifier for each WTRU and the transmission time occurs within the indicated time interval; transmitting the uplink transmission from the WTRU at the determined transmission time over the resource, wherein the WTRU is the only WTRU in the group of WTRUs with access to the resource at the determined transmission time; and releasing the resource in response to completing the uplink transmission.
