The indication may or may not indicate how much it can be prioritized. If the indication cannot indicate how much it can be prioritized, the MAC CE (e.g. sidelink BSR/New uplink MAC CE/Timer controlled based MAC CE) will be prioritized over what MAC CE or what data should be predefined. If the indication indicates how much it can be prioritized, the indication may include sort of index (e.g. LCP rule position, etc.) or value (e.g. priority) or bitmap (e.g. priority bitmap or LCP rule position bitmap) for informing the prioritized result. By this way, the UE can transmit less SR transmission and reduce power consumption.
Solution 3 (Keep using ongoing SR configuration instead of initiating SR transmission based on a different SR configuration for new arrival data)—The UE will keep transmitting SR transmission based on current used SR configuration, regardless of what new coming event is. The SR configuration used to performing SR transmission may be updated if SR triggering event related to current SR transmission is cancelled.
Solution 4 (Decide whether to change SR configuration based on latency)—The UE will decide whether to use a SR configuration related to new event based on latency requirement of new coming event (e.g. regular BSR for a logical channel or Potential new MAC CE). If the latency requirement related to new event is tighter than latency requirement of any other current SR triggering event(s), the UE will initiate SR transmission based on SR configuration related to new event. Regarding ongoing SR transmission, the UE may or may not stop current SR transmission even if a new SR transmission for a different SR configuration is initiated.
