Section: 5.2.2.4.10 Actions upon reception of SIB9
Content: Upon receiving SIB9 with referenceTimeInfo, the UE may perform the related actions except for the action of ignoring all further referenceTimeInfo received in SIB9 as specified in clause 5.7.1.3. Upon receiving SIB9 with eventID-TSS, the UE shall perform the related actions if requested by upper layers: 1> if VarEventID has an entry with a storedEventID value: 2> if the storedEventID value within VarEventID is different from the eventID-TSS value received within SIB9: 3> consider that the content of clockQualityDetailsLevel may have changed; 3> notify upper layers that clockQualityDetailsLevel may have changed; 3> replace the storedEventID value within VarEventID with the eventID-TSS value received within SIB9; 3> replace the storedGnbID value within VarGnbID with the gNB identity value received within SIB1; 2> else: 3> if the VarGnbID has an entry with a storedGnbID value: 4> if the storedGnbID value within VarGnbID is different from the gNB identity value received within SIB1: 5> consider that the content of clockQualityDetailsLevel may have changed; 5> notify upper layers that clockQualityDetailsLevel may have changed; 5> replace the storedGnbID value within VarGnbID with the gNB identity value received within SIB1; NOTE: The UE should calculate the value of the gNB identity as the value of gNB-ID-Length leftmost bits of the 36-bit long cellIdentity in the first PLMN-IdentityInfo IE of PLMN-IdentityInfoList in SIB1. 1> else: 2> add a new entry of storedEventID within the VarEventID with the eventID-TSS value received within SIB9; 2> add a new entry of storedGnbID within the VarGnbID with the gNB identity value received within SIB1; 2> notify upper layers that clockQualityDetailsLevel may have changed;
