Section: 5.7.1.3 Reception of the DLInformationTransfer by the UE
Content: Upon receiving DLInformationTransfer message, the UE shall: 1> if dedicatedNAS-Message is included: 2> forward dedicatedNAS-Message to upper layers. 1> if referenceTimeInfo is included: 2> calculate the reference time based on the time, referenceSFN and timeInfoType if it is included; 2> calculate the uncertainty of the reference time based on the uncertainty, if uncertainty is included; 2> inform upper layers of the reference time and, if uncertainty is included, of the uncertainty; 2> ignore all further referenceTimeInfo received in SIB9, if any. 1> if sib9Fallback is included: 2> apply referenceTimeInfo in SIB9. 1> if rxTxTimeDiff-gNB is included: 2> calculate the propagation delay based on the UE Rx-Tx time difference measurement and the received Rx-Tx time difference measurement at the gNB; 2> inform upper layers of the propagation delay. 1> if ta-PDC is set to activate: 2> inform upper layers of the propagation delay determined by the accumulated Timing Advance commands. 1> if clockQualityDetailsLevel is included: 2> if eventID-TSS is included: 3> if VarEventID has an entry with a storedEventID value: 4> replace the storedEventID value within VarEventID with the eventID-TSS value received with clockQualityDetailsLevel; 3> else: 4> add a new entry of storedEventID within the VarEventID with a value set as the one of eventID-TSS value received with clockQualityDetailsLevel; 2> if the VarGnbID has an entry with a storedGnbID value: 3> replace the storedGnbID value within VarGnbID with the gNB identity value received within SIB1; 2> else: 3> add a new entry of storedGnbID within the VarGnbID with the gNB identity value received within SIB1. 2> forward clockQualityDetailsLevel to upper layers. Upon receiving DLInformationTransfer message, the IAB-MT shall: 1> if dedicatedInfoF1c is included: 2> forward dedicatedInfoF1c to the collocated IAB-DU.
