1. A method for performing radio link monitoring comprising:
performing, by a user equipment (UE), a radio link monitoring (RLM) procedure with first RLM parameters;
receiving, at the UE, a message including at least one second RLM parameter, wherein the first RLM parameters and the at least one second RLM parameter are RLM reference signal, RLM-RS, resources for in sync and out of sync indications;
identifying, by the UE, a difference between the first RLM parameters and the at least one second RLM parameter, wherein identifying the difference between the first RLM parameters and the at least one second RLM parameter comprises:
identifying that the first RLM parameters are a first group of RLM-RS resources, and
identifying that the at least one second RLM parameter is a second group of RLM-RS resources added to the first group of RLM-RS resources;
resetting, at the UE, at least one of the first RLM parameters in response to identifying the difference between the first RLM parameters and the at least one second RLM parameter and
evaluating, by the UE, the first and second groups of RLM-RS resources by evaluating the second group of RLM-RS resourced before evaluating the first group of RLM-RS resources.
