Transmission of first and second buffer status information messages in a wireless network
Abstract
A wireless transmit/receive unit (WTRU) transmits a first buffer status information message over an uplink shared channel with buffered data and a second buffer status information message over the uplink shared channel with buffered data. The second buffer status information message may have less bits and use a different format than the first buffer status information message. The WTRU may also transmit a scheduling request without buffered data on a condition of not have a scheduling grant. The WTRU may initiate, subsequent to a predetermined number of subframes after transmission of the first buffer status information message, transmission of another first buffer status information message.
