Option 4 (Monitoring control channel(s) responsible for scheduling the largest or smallest numerology related to the multiple bits setting of the last SR transmission)—In this option, UE always monitors either largest or smallest numerology. The largest or smallest numerology could be limited to those numerologies informed by SR transmission. The network (e.g. base station) will share the same understanding and schedule based on the same rule. By limiting number of control channels for monitoring, the power consumption could be reduced.
Moreover, since the UE may have multiple control channels for different numerologies, the UE may monitor other control channel which are not largest or smallest based on conditions other than SR transmission. The conditions other than SR transmission could be one or multiple options listed in below:
- 1. DurationTimer is running
- 2. drx-InactivityTimer is running
- 3. drx-RetransmissionTimer is running
- 4. drx-ULRetransmissionTimer is running
- 5. ContentionResolutionTimer is running
- 6. An uplink grant for a pending HARQ retransmission can occur and there is data in the corresponding HARQ buffer for synchronous HARQ process
- 7. A PDCCH indicating a new transmission addressed to the C-RNTI of the MAC entity has not been received after successful reception of a Random Access Response for the preamble not selected by the MAC entity.
- 8. A sidelink grant for a pending HARQ (re-)transmission can occur.
