  • Patent number: 10333683
    Abstract: Different Out-of-sync thresholds are defined for Radio Link Monitoring by a UE having a selectively enabled advanced receiver feature. When the advanced receiver feature is disabled, the UE monitors received signal quality and compares a signal quality metric to a first threshold developed for a reference receiver. When the advanced receiver feature is enabled, the UE compares the signal quality metric to a second threshold indicating lower signal quality than the first threshold. In either case, if the signal quality meets the respective threshold, the UE goes Out-of-sync. The Out-of-sync UE continues to monitor received signal quality. Regardless of whether the advanced receiver feature is enabled or not, a third threshold, developed for the reference receiver, is applied to determine when to return to In-sync. In one embodiment, the reference receiver enables two antennas, and the advanced receiver feature is enabling four antennas.
