Patent ID: 8477695

Claim:
A method for a wireless transmit/receive unit (WTRU) transmitting an uplink (UL) scheduling request upon having buffered data to transmit to a Node-B, and needing a scheduling grant for UL data transmission, the method comprising: the WTRU selecting a type of UL scheduling request to transmit to the Node-B, the type selected from at least one of a short-version UL scheduling request and a full-version UL scheduling request, wherein the short-version UL scheduling request is a one-bit indicator or a multi-bit indicator, and wherein the short-version UL scheduling request indicates the amount of scheduling grant or resources requested and wherein the full-version UL scheduling request includes detailed information related to at least one of a WTRU buffer status and a WTRU link budget; wherein the WTRU transmits the full-version UL scheduling request on a condition that at least a predetermined number of sub-frames elapsed since the last time a full-version UL scheduling request was transmitted and the WTRU has a scheduling grant; and the WTRU transmitting the selected type of UL scheduling request to the Node-B.
