Section: 5.3.5.4 Secondary cell group release
Content: The UE shall: 1> as a result of SCG release triggered by E-UTRA (i.e. (NG)EN-DC case) or NR (i.e. NR-DC case): 2> reset SCG MAC, if configured; 2> for each RLC bearer that is part of the SCG configuration: 3> perform RLC bearer release procedure as specified in 5.3.5.5.3; 2> for each BH RLC channel that is part of the SCG configuration: 3> perform BH RLC channel release procedure as specified in 5.3.5.5.10; 2> release the SCG configuration; 2> for all application layer measurement configurations that are part of the SCG configuration: 3> inform upper layers about the release of the application layer measurement configurations; 3> discard any application layer measurement reports which were not yet submitted to lower layers for transmission; 2> remove all the entries within the SCG VarConditionalReconfig, if any; 2> if SCG release was triggered by NR (i.e. NR-DC case): 3> remove all the entries in the condReconfigList within the MCG VarConditionalReconfig for which the RRCReconfiguration within condRRCReconfig does not include the masterCellGroup with reconfigurationWithSync and for which subsequentCondReconfig is not present, if any; 2> else (i.e. EN-DC case): 3> perform VarConditionalReconfiguration CPC removal as specified in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [10] clause 5.3.5.9.7; 2> stop timer T310 for the corresponding SpCell, if running; 2> stop timer T312 for the corresponding SpCell, if running; 2> stop timer T304 for the corresponding SpCell, if running. NOTE: Release of cell group means only release of the lower layer configuration of the cell group but the RadioBearerConfig may not be released.
