Prediction and Proactive Handling of Radio Link Failures

A method for a user equipment (UE) configured to communicate with a wireless network via a primary cell (PCell) and one or more secondary cells (SCells), the method comprising:

• receiving, from the wireless network, a plurality of configurations for a corresponding plurality of candidate PCells;
• selecting one of the configurations upon occurrence of a failure event in a first cell configured as the PCell;
• and
• switching the PCell from the first cell to the candidate PCell corresponding to the selected configuration.

A method for a network node configured to communicate with a user equipment (UE) via a primary cell (PCell) and one or more secondary cells (SCells) in a wireless network, the method comprising:

• sending, to the UE, a plurality of configurations for a corresponding plurality of candidate PCells;
• selecting one of the configurations upon occurrence of a failure event in a first cell configured as the PCell;
• and
• switching the PCell from the first cell to the candidate PCell corresponding to the selected configuration.

A user equipment (UE) configured to communicate with a wireless network via a primary cell (PCell) and one or more secondary cells (SCells), the UE comprising:

• communication interface circuitry configured to communicate with the wireless network via the PCell and the one or more SCells;
• and
• processing circuitry operably coupled to the communication interface circuitry, whereby the communication interface circuitry and processing circuitry are configured to:
• receive, from the wireless network, a plurality of configurations for a corresponding plurality of candidate PCells;
• select one of the configurations upon occurrence of a failure event in a first cell configured as the PCell;
• and
• switch the PCell from the first cell to the candidate PCell corresponding to the selected configuration.
