Method and apparatus for requesting resource for control element transmission in a wireless communication system

Assuming not all PDCCHs (e.g. all control resource sets) can schedule sidelink resource, if the SR could indicate sidelink BSR existence, the UE will monitor PDCCH(s) which can schedule sidelink resources. And which PDCCH can be used to schedule sidelink resource may be decided by sidelink related configuration (e.g. communication configuration, pool configuration, or numerology configuration) and/or cell configuration.
The association could be predefined. For example, UE monitors default control channel for special event.
Option 7 (Monitoring control channel(s) for uplink)—In this option, control channels could be separated into two sets or three sets. The first set is used for uplink scheduling. The second set is used for downlink scheduling. The third set is used for both downlink scheduling and uplink scheduling. After UE transmits SR transmission, the UE will monitor the first set and/or the third set. Moreover, the second set may be monitor based on conditions listed below, instead of SR transmission condition.
The conditions could be one or multiple options listed 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
