For example, network can provide a threshold related to priority of uplink logical channel to decide whether Timer controlled based MAC CE is more important than regular uplink BSR. If BSR is for reporting data belonging to a logical channel with priority above the threshold, the regular uplink BSR is more important. Alternatively, the regular uplink BSR could be more important if BSR is for reporting data belonging to a logical channel with priority below the threshold. There could be more than one thresholds (or called limitation) for creating a range for prioritization. The priority of uplink logical channel could be replaced to QoS flow.
As another example, the network can provide an indication in a logical channel configuration or in a service configuration (e.g. V2X, relay, MBMS, URLLC, full-duplex, etc.) or in MAC CE related configuration. If such indication is included, the priority could be prioritized.
In one embodiment, if the indication is in a logical channel configuration, the regular uplink BSR will be prioritized if the data becoming available for that logical channel. Furthermore, if the indication is in a service configuration (e.g. V2V, D2D relay, etc.), the BSR will be prioritized if the data becoming available for service. In addition, if the indication is in a MAC CE related configuration, the MAC CE will be prioritized.
