11 Radio information related interactions between network nodes p. 1493

11.1 General p. 1493

This clause specifies RRC messages that are transferred between network nodes. These RRC messages may be transferred to or from the UE via another Radio Access Technology. Consequently, these messages have similar characteristics as the RRC messages that are transferred across the NR radio interface, i.e. the same transfer syntax and protocol extension mechanisms apply.

11.2 Inter-node RRC messages p. 1493

11.2.1 General p. 1493

This clause specifies RRC messages that are sent either across the X2-, Xn- or the NG-interface, either to or from the gNB, i.e. a single 'logical channel' is used for all RRC messages transferred across network nodes. The information could originate from or be destined for another RAT.

11.2.3 Mandatory information in inter-node RRC messages p. 1528

For the AS-Config transferred within the HandoverPreparationInformation:

The source node shall include all fields necessary to reflect the current AS configuration of the UE, except for the fields sourceSCG-NR-Config, sourceSCG-EUTRA-Config and sourceRB-SN-Config, which can be omitted in case the source MN did not receive the latest configuration from the source SN. For RRCReconfiguration included in the field rrcReconfiguration, ReconfigurationWithSync is included with only the mandatory subfields (e.g. newUE-Identity and t304) and ServingCellConfigCommon;
Need codes or conditions specified for subfields according to IEs defined in clause 6 do not apply. I.e. some fields shall be included regardless of the "Need" or "Cond" e.g. discardTimer;
Based on the received AS configuration, the target node can indicate the delta (difference) to the current AS configuration (as included in HandoverCommand)to the UE. The fields newUE-Identity and t304 included in ReconfigurationWithSync are not used for delta configuration purpose.

The candidateCellInfoListSN(-EUTRA) in CG-Config and the candidateCellInfoListMN(-EUTRA)/ candidateCellInfoListSN(-EUTRA) in CG-ConfigInfo need not be included in procedures that do not involve a change of node.

For fields scg-CellGroupConfig, scg-CellGroupConfigEUTRA and scg-RB-Config in CG-Config (sent upon SN initiated SN change or other conditions as specified in field descriptions) and fields mcg-RB-Config, scg-RB-Config and sourceConfigSCG in CG-ConfigInfo (sent upon change of SN):

The source node shall include all fields necessary to reflect the current AS configuration of the UE, unless stated otherwise in the field description. For RRCReconfiguration included in the field scg-CellGroupConfig in CG-Config, ReconfigurationWithSync is included with only the mandatory subfields (e.g. newUE-Identity and t304) and ServingCellConfigCommon;
Need codes or conditions specified for subfields according to IEs defined in clause 6 do not apply;
Based on the received AS configuration, the target node can indicate the delta (difference) as compared to the current AS configuration to the UE. The fields newUE-Identity and t304 in ReconfigurationWithSync are always included by the target node, i.e. they are not used for delta configuration purpose to UE.

For fields in CG-Config and CG-ConfigInfo listed below, absence of the field means that the receiver maintains the values informed via the previous message. Note that every time there is a change in the configuration covered by a listed field, the MN or SN shall include the field and it shall provide the full configuration provided by that field unless stated otherwise. Otherwise, if there is no change, the field can be omitted:

configRestrictInfo;
gapPurpose;
measGapConfig (for which delta signaling applies);
measGapConfigFR2 (for which delta signaling applies);
measResultCellListSFTD;
measResultSFTD-EUTRA;
sftdFrequencyList-EUTRA;
sftdFrequencyList-NR;
ue-CapabilityInfo;
servFrequenciesMN-NR.

For other fields in CG-Config and CG-ConfigInfo, the sender shall always signal the appropriate value even if same as indicated in the previous inter-node message, unless explicitly stated otherwise.

– ResourceConfigNRDC p. 1529

The IE is used to indicate or request the maximum values that can be used by the SCG in NR-DC, with each value equal to or lower than the value of the corresponding field in the UE capability, as reported by the UE, unless specified otherwise.

12 Processing delay requirements for RRC procedures p. 1533

The UE performance requirements for RRC procedures are specified in the following tables. The performance requirement is expressed as the time in [ms] from the end of reception of the network → UE message on the UE physical layer up to when the UE shall be ready for the reception of uplink grant for the UE → network response message with no access delay other than the TTI-alignment (e.g. excluding delays caused by scheduling, the random access procedure or physical layer synchronisation). In case the RRC procedure triggers BWP switching, the RRC procedure delay is the value defined in the following table plus the BWP switching delay defined in clause 8.6.3 of TS 38.133.
