B. If Mode 1 (i.e. sl-ScheduledConfig) is configured in sl-ConfigDedicatedNR: While T304 is running, use the exceptional resource pool for SL transmission, if the UE is configured with sl-TxPoolExceptional included in sl-ConfigDedicatedNR for the concerned frequency in RRCReconfiguration
C. Else if Mode 2 (i.e. sl-UE-SelectedConfig) is configured in sl-ConfigDedicatedNR: Until sensing results are available for the normal TX pool, use the exceptional resource pool for SL transmission if the UE is configured with sl-TxPoolExceptional for the concerned frequency in RRCReconfiguration
D. The SL operation is performed using the target cell MAC entity
7. The UE performs the DL sync and the RA procedure towards the target cell.
8. Upon completion of the RA procedure:
9. Upon completion of the RA procedure (or upon receiving source release indication in the RRC reconfiguration message):
-
- If dapsConfig is configured for any DRB and if ContinueSLOperationinSource is received in the RRCReconfiguration message in operation 2:
- i. The UE applies the target PCell's sidelink configuration (i.e. sl-ConfigDedicatedNR received in the RRC Reconfiguration message including reconfigurationWithSync in operation 2)
