Wireless communication method and apparatus for selecting between transmission of short-version and full-version uplink scheduling requests |
摘要 |
In a wireless communication system including a wireless transmit/receive unit (WTRU) and a Node-B, an uplink (UL) scheduling request is transmitted by the WTRU to the Node-B when the WTRU has buffered (user) data to transmit to the Node-B, but needs to have a scheduling grant for UL data transmission. The WTRU determines whether to transmit to the Node-B a short-version UL scheduling request or a full-version UL scheduling request, whereby the short-version UL scheduling request uses less channel resources than the full-version UL scheduling request by omitting information pertaining to WTRU status parameters. The short-version UL scheduling request is a one-bit indicator or a multi-bit indicator that indicates an amount of scheduling grants or resources requested. The full-version UL scheduling request includes at least one of a WTRU buffer status and a WTRU link budget.
