Abstract
A user equipment (UE) transmits a burst information report (BIR) medium access control (MAC) control element. For each reported uplink burst of a logical channel group (LCG), it carries a burst identifier and a per-LCG report sequence number. The UE triggers an updated BIR when the predicted burst size changes by more than a relative size threshold, or when the predicted arrival time changes by more than a threshold that scales with the remaining time. Only a change that exceeds an urgent multiple of the threshold bypasses a running BIR prohibit timer. A network node that detects a sequence-number gap sends a downlink BIR resynchronization request. Until the UE returns a full-state BIR, the node pre-schedules for the larger of the stored and reported sizes. After a cancellation, the UE repeats the cancellation when it receives a configured number of grants that it fills only with padding.
