Section: 5.3.5.5.4 RLC bearer addition/modification
Content: For each RLC-BearerConfig received in the rlc-BearerToAddModList IE the UE shall: 1> if the UE's current configuration contains an RLC bearer with the received logicalChannelIdentity/LogicalChannelIdentityExt within the same cell group: 2> if the RLC bearer is associated with an DAPS bearer, or 2> if any DAPS bearer is configured and the RLC bearer is associated with an SRB: 3> reconfigure the RLC entity or entities for the target cell group in accordance with the received rlc-Config; 3> reconfigure the logical channel for the target cell group in accordance with the received mac-LogicalChannelConfig; 2> else: 3> if reestablishRLC is received: 4> re-establish the RLC entity as specified in TS 38.322[ NR; Radio Link Control (RLC) protocol specification ]  [4]; 3> reconfigure the RLC entity or entities in accordance with the received rlc-Config; 3> reconfigure the logical channel in accordance with the received mac-LogicalChannelConfig; 3> if servedMBS-RadioBearer is received: 4> associate this logical channel with the PDCP entity identified by servedMBS-RadioBearer; NOTE 1: For DRB and SRB, the network does not re-associate an already configured logical channel with another radio bearer. Hence, servedRadioBearer is not present in this case. For MRB, the network does not re-associate an already configured logical channel with DRB or SRB or another MRB (i.e. MRB with another PDCP entity). Hence multicastRLC-BearerConfig is not present in this case. If a radio bearer is released and another is added with the same radio bearer identity, it is considered as a new (different) radio bearer. Hence, the network also releases the RLC bearer(s) associated with the released radio bearer. NOTE 2: In DAPS handover, the UE may perform RLC entity re-establishment (if reestablishRLC is set) for an RLC bearer associated with a non-DAPS bearer when indication of successful completion of random access towards target cell is received from lower layers as specified in TS 38.321[ NR; Medium Access Control (MAC) protocol specification ]  [3]. 1> else (a logical channel with the given logicalChannelIdentity/LogicalChannelIdentityExt is not configured within the same cell group, including the case when full configuration option is used): 2> if the servedRadioBearer associates the logical channel with an SRB and rlc-Config is not included: 3> establish an RLC entity in accordance with the default configuration defined in 9.2 for the corresponding SRB; 2> else: 3> establish an RLC entity in accordance with the received rlc-Config; 2> if the servedRadioBearer associates the logical channel with an SRB and if mac-LogicalChannelConfig is not included: 3> configure this MAC entity with a logical channel in accordance to the default configuration defined in 9.2 for the corresponding SRB; 2> else: 3> configure this MAC entity with a logical channel in accordance to the received mac-LogicalChannelConfig; 2> associate this logical channel with the PDCP entity identified by servedRadioBearer or servedMBS-RadioBearer.
