36.523-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core (EPC)Part 1: Protocol conformance specificationRelease 16TSUser Equipment (UE) conformance specification

22.4.18.1 Test Purpose (TP)

(1)

with { UE in E-UTRA RRC_CONNECTED state}

ensure that {

when { UE receives an RRCConnectionReconfiguration-NB message containing SRB reconfiguration }

then { UE reconfigures affected SRBs and sends an RRCConnectionReconfigurationComplete-NB message }

}

22.4.18.2 Conformance requirements

References: The conformance requirements covered in the current TC is specified in: TS 36.331, clauses 5.3.5.3 and 5.3.10.1.

[TS 36.331, clause 5.3.5.3]

If the RRCConnectionReconfiguration message does not include the mobilityControlInfo and the UE is able to comply with the configuration included in this message, the UE shall:

1> else:

2> if the RRCConnectionReconfiguration message includes the radioResourceConfigDedicated:

3> perform the radio resource configuration procedure as specified in 5.3.10;

[TS 36.331, clause 5.3.10.1]

The UE shall:

1> if the UE is a NB-IoT UE and SRB1 is established; or

1> for each srb-Identity value included in the srb-ToAddModList that is part of the current UE configuration (SRB reconfiguration):

2> reconfigure the RLC entity in accordance with the received rlc-Config;

2> reconfigure the DCCH logical channel in accordance with the received logicalChannelConfig;
