Multiple rlf detections for l1/l2 inter-cell mobility

A User Equipment device, UE, comprising

• a memory that stores computer-executable instructions;
• and
• a processor that executes the computer-executable instruction to perform operations, comprising:
• receiving one or more L1/L2 inter-cell mobility candidate cell configurations;
• performing a plurality of Radio Link Monitoring, RLM, processes based on parameters of one or more of a serving cell configuration and one or more of the L1/L2 inter-cell mobility candidate cell configurations;
• declaring a Radio Link Failure, RLF, on one or more of the serving cell or the one or more L1/L2 inter-cell mobility candidate cells;
• performing a network operation based on a type of the RLF.

A method performed by a first network node of a serving cell for performing Radio Link Monitoring, RLM, and Radio Link Failure, RLF, detection, the method comprising:

• receiving, from User Equipment device, UE, an indication that an RLF has been declared on a L1/L2 inter-cell mobility cell for which a configuration has been provided to the UE by the first network node;
• providing to the UE a new Radio Resource Control, RRC, message, the RRC message comprising at least one of:
• a configuration to reconfigure the L1/L2 inter-cell mobility cell;
• a layer 1 signaling indicating L1/L2 inter-cell mobility execution to a L1/l2 inter-cell mobility candidate cell;
• and
• an indication to remove the L1/L2 inter-cell mobility cell;
• providing a message to a second network node, the message comprising at least one of:
• an indication on which L1/L2 inter-cell mobility cell the RLF was declared;
• an indication that a layer 1 signal indicating L1/L2 inter-cell mobility execution to a L1/L2 inter-cell mobility candidate cell has been sent to the UE;
• and
• a new configuration for L1/L2 inter-cell mobility cell to be sent to the UE.

A method performed by a first network node of a Central Unit, CU, for performing Radio Link Monitoring, RLM, and Radio Link Failure, RLF, detection, the method comprising:

• receiving from a second network node of a serving cell or a candidate cell a message comprising at least one of:
• an indication on which L1/L2 inter-cell mobility cell of a group of L1/L2 inter-cell mobility cells a RLF was declared by a User Equipment device, UE;
• an indication that layer 1 signal indicating L1/L2 mobility execution to a L1/L2 inter-cell mobility candidate cell has been sent to the UE;
• and
• a new configuration for L1/L2 inter-cell mobility to be sent to the UE;
• providing a message to the UE, wherein the message includes a new configuration for L1/L2 inter-cell mobility.
