Option 5 (Monitoring control channel(s) which can schedule most numerologies related to SR configuration(s) with triggered SR or most numerologies UE is configured with or UE can support)—In this option, UE will select control channel which schedule more numerology for reducing power consumption on monitoring. The UE may take only those numerologies related to SR configuration(s) with triggered SR into account for calculating number of numerologies scheduled by a control channel.
Option 6 (Monitoring specific control channel(s) associated with the special SR triggering event)—In this option, since UE knows SR is triggered for special event and network will share the same understanding based on received SR, the UE could monitor control channel(s) associated with special SR triggering event, instead of all control channels.
The association could be configured by network (e.g. base station). The association could be provided in service configuration (e.g. sidelink configuration), control channel configuration (e.g. include control element identity in control channel configuration), cell configuration (e.g. both control channel and control element belong to same cell), or other possible RRC configuration provided through system information or dedicated signaling. For example, a sidelink BSR triggers a SR and the SR is transmitted to the network.
