Methods for enhanced radio link failure recovery

A wireless device, comprising:

• wireless communication circuitry;
• and
• at least one processor coupled to the wireless communication circuitry and configured to cause the wireless device to:
• establish a radio resource control (RRC) connection with a first cell of a network;
• transmit, to the network, signaling comprising an indication of enhanced radio link failure (RLF) recovery capability;
• receive, from the network, one or more RRC messages comprising conditional handover (CHO) configuration information for at least one or more candidate cells, wherein the CHO configuration information comprises one or more enhanced RLF recovery configurations associated with the one or more candidate cells, and wherein each of the one or more enhanced RLF recovery configurations correspond to one or more distinct validity periods configured by the cellular network;
• detect one or more RLFs;
• apply, in response to detecting the one or more RLFs, the CHO information to the one or more candidate cells;
• and
• transmit, in response to applying the CHO configuration information, signaling comprising a trigger indicating a RLF recovery to the network;
• re-establish the RRC connection with the network using the CHO configuration information.

An apparatus, comprising:

• a processor configured to when executing instructions stored in a memory, perform operations comprising:
• establishing a radio resource control (RRC) connection with a user equipment (UE);
• transmitting, to the UE, a capability request message;
• receiving, in response to the capability request message, signaling from the UE comprising an indication of an enhanced radio link failure (RLF) recovery capability;
• transmitting, to the UE, one or more RRC messages comprising configuration information;
• configuring one or more validity periods corresponding to the configuration information;
• receiving, from the UE, signaling comprising a trigger indicating a RLF recovery;
• and
• re-establishing, in response to receiving the trigger, the RRC connection with the UE using the configuration information.
