Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A non-transitory computer readable medium comprising program instructions for causing a terminal to perform at least the following:
triggering a communication failure process according to a configuration of a RLC layer entity, when the RLC layer entity reaches a maximum number of retransmission times;
when a carrier set configured for a logical channel corresponding to the RLC layer entity comprises a Primary Cell (PCell), triggering the communication failure process according to the configuration of the RLC layer entity comprises:
triggering a radio link failure process of a Master Cell Group (MCG);
wherein the triggering the radio link failure process comprises the following steps:
suspending all radio bearers except a signal radio bearer SRB0;
resetting a MAC layer; and
initializing transmission of an RRC connection reestablishment request message;

when a carrier set configured for a logical channel corresponding to the RLC layer entity comprises a Primary Secondary Cell (PSCell), triggering the communication failure process according to the configuration of the RLC layer entity comprises:
triggering a radio link failure process of a Secondary Cell Group (SCG);
wherein the triggering the radio link failure process comprises the following steps:
suspending all SCG DRBs and suspending SCG transmission for split DRBs;
resetting a SCG MAC layer; and
initializing transmission of a SCG radio link failure message to a network;

when a carrier set configured for a logical channel corresponding to the RLC layer entity only comprises one or more Secondary Cells (SCells), triggering the communication failure process according to the configuration of the RLC layer entity comprises:
triggering reporting of a radio link failure of the SCell.
