Method and apparatus for uplink scheduling signaling in a wireless communication
Abstract
A method and apparatus for efficient uplink scheduling grant and scheduling request signaling for evolved universal terrestrial radio access (E-UTRA) are disclosed. A wireless transmit/receive unit sends an uplink scheduling request to a Node-B, whereby the Node-B sends the uplink scheduling grant in response to the uplink scheduling request. The uplink scheduling request includes a data buffer occupancy value that indicates the amount of data that needs to be transmitted in the uplink. The amount of data is quantized to integer factors of the number of bits that may be supported by one RB, and mapped to an index value with N-bit mapping having less than full resolution. The uplink scheduling grant assigns a number of resource blocks to the WTRU for uplink transmission. The number of RBs allocated is mapped to an index value using N-bit mapping having less than full resolution.
