MCG FAILURE RECOVERY ENHANCEMENT IN DC MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17598093 titled 'MCG FAILURE RECOVERY ENHANCEMENT IN DC MODE
Simplified Explanation
This patent application describes methods and systems for a wireless communication device (UE) to recover from radio link failures in a multi-radio dual connectivity (MR-DC) system. Specifically, it focuses on situations where the secondary cell group (SCG) is deactivated or not enabled.
- The UE can activate the SCG when a radio link failure is detected and the SCG is deactivated, allowing the UE to use the SCG link for transmitting and receiving signaling messages or data during the recovery process.
- If the UE is configured to add the SCG under certain conditions but those conditions have not been met, the UE can check if the MCG link failure is one of the conditions and if the radio link quality of the SCG is above a certain threshold.
- If the radio link quality of the SCG exceeds the threshold, the UE can apply the SCG configuration to add the SCG, even if the other conditions for adding the SCG have not been satisfied.
Original Abstract Submitted
Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.
