Section: 5.7.3.2 Initiation
Content: A UE initiates the procedure to report SCG failures when neither MCG nor SCG transmission is suspended and when one of the following conditions is met: 1> upon detecting radio link failure for the SCG, in accordance with clause 5.3.10.3; 1> upon detecting beam failure of the PSCell while the SCG is deactivated, in accordance with TS 38.321[ NR; Medium Access Control (MAC) protocol specification ] [3]; 1> upon reconfiguration with sync failure of the SCG, in accordance with clause 5.3.5.8.3; 1> upon SCG configuration failure, in accordance with clause 5.3.5.8.2; 1> upon integrity check failure indication from SCG lower layers concerning SRB3. Upon initiating the procedure, the UE shall: 1> if the procedure was not initiated due to beam failure of the PSCell while the SCG is deactivated: 2> suspend SCG transmission for all SRBs, DRBs and, if any, BH RLC channels; 2> reset SCG MAC; 1> stop T304 for the SCG, if running; 1> stop conditional reconfiguration evaluation for CPC, CPA, or subsequent CPAC, if configured; 1> stop conditional reconfiguration evaluation for each CHO configuration that includes condExecutionCondPSCell, if configured; 1> if the UE is in (NG)EN-DC: 2> initiate transmission of the SCGFailureInformationNR message as specified in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [10], clause 5.6.13a. 1> else: 2> initiate transmission of the SCGFailureInformation message in accordance with 5.7.3.5.
