Abstract:
1. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising: maintaining token buckets for respective radio bearers (RBs); determining current buffer status information, wherein the current buffer status information includes (i) values of the token buckets and (ii) buffer levels associated with the RBs, wherein the buffer levels are indicative of respective amounts of uplink (UL) data for transmission via the RBs; triggering a buffer status report (BSR) responsive to one or more buffer levels exceeding respective thresholds, and wherein the BSR comprises the one or more buffer levels; triggering a grant request in connection with the triggering of the BSR; receiving a grant including an indication of an amount of UL resources; and utilizing the UL resources, wherein at least one of the values of the token buckets is a negative value after the UL resources are utilized.
