Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) supporting a fast Master Cell Group (MCG) link recovery for Multi Radio-Dual Connectivity (MR-DC) is provided. The method comprising: initiating the fast MCG link recovery, based on occurrence of a radio link failure (RLF) in MCG; and in case that failure of the fast MCG link recovery is identified, transmitting a RLF report including cause information indicating at least one of expiry of a timer, secondary cell group (SCG) deactivation or SCG failure.
Claims15
A method (300, 400, 500, 600, 700, 800, 900, 1000, 1100) performed by a user equipment (UE) (102) supporting a fast Master Cell Group (MCG) link recovery for Multi Radio-Dual Connectivity (MR-DC), comprising:
- initiating the fast MCG link recovery, based on occurrence of a radio link failure (RLF) in MCG;
- and
- in case that failure of the fast MCG link recovery is identified, transmitting a RLF report including cause information indicating at least one of expiry of a timer, secondary cell group (SCG) deactivation or SCG failure.
A User Equipment (UE) (102), comprising:
- a transceiver;
- and
- a processor (106) coupled with the transceiver and configured to:
- initiate a fast master cell group (MCG) link recovery, based on occurrence of a radio link failure (RLF) in MCG;
- in case that failure of the fast MCG link recovery is identified, transmit a RLF report including cause information indicating at least one of expiry of a timer, secondary cell group (SCG) deactivation or SCG failure.
A network (104), comprising:
- a transceiver;
- and
- a processor (112) coupled with the transceiver and configured to:
- receive at least one User Equipment (UE) capability information from a UE (102), wherein the at least one UE capability information informs whether the UE (102) is capable of supporting of Self-Organizing Network (SON)/Minimization of Drive Test (MDT) enhancements for a fast Master Cell Group (MCG) link recovery;
- receive a Radio Link Failure (RLF) report from the UE (102) indicating the status of the fast MCG link recovery, if an RLF has occurred in MCG and the UE (102) is capable of supporting the SON/MDT enhancements for the fast MCG link recovery;
- and
- perform a plurality of optimizing procedures for optimizing mobility of the UE (102) using the received status of the fast MCG link recovery.
