Title: RADIO LINK MONITORING FOR MULTI-BEAM COMMUNICATIONS
Abstract:
A technique includes determining, by a user device, a primary beam and a secondary beam; counting synchronization conditions for the primary beam using at least a first synchronization counter and synchronization conditions for the secondary beam using at least a second synchronization counter; determining, based on an association of each of the counters with either the primary beam or the secondary beam, a first threshold counter value for the first synchronization counter for the primary beam and a second threshold counter value for the second synchronization counter for the secondary beam; determining a primary beam link status for the primary beam and a secondary beam link status for the secondary beam based on the counting and the threshold counter values; and updating a radio link failure (RLF) status for the user device based on at least one of the primary beam link status and the secondary beam link status.
