Abstract
Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for performing radio link monitoring or beam failure detection (RLM/BFD) in, or related to, a new radio (NR) involved network. Various embodiments are directed to adaptive configuration of threshold values for in-sync and/or out-of-sync (IS/OOS) in the NR involved network and adequately performing RLM/BFD. Such RLM/BFD with adaptive IS/OOS configuration may improve measurement accuracy and system performance. Other embodiments may be described and claimed.
Claims20
A non-transitory computer-readable medium (CRM) comprising instructions to, upon execution of the instructions by one or more processors of a user equipment (UE), cause the UE to perform operations, the operations comprising:
- decoding, upon reception of one or more radio link monitoring or beam failure detection (RLM/BFD) reference signal (RS) configurations, information that indicates a target RLM/BFD RS for monitoring radio link or detecting beam failure;
- decoding, upon reception of one or more radio tracking reference signal (TRS) configurations, information that indicates one or more TRS;
- receiving a TRS based on the decoded one or more TRS configurations;
- determining whether the target RLM/BFD RS and the received TRS are quasi co-located (QCLed);
- deriving a set of threshold values for an in-sync (IS)/out-of-sync (OOS) classification based on a set of channel parameters that are estimated based on the received TRS of a received RS, responsive to the target RLM/BFD RS and the received TRS are QCLed;
- and
- updating the set of threshold values for the IS/OOS classification with respect to the target RLM/BFD RS.
A user equipment (UE), comprising:
- interface circuitry configured to:
- receive a radio link monitoring (RLM) or beam failure detection (BFD) reference signal (RS) configuration that indicates a RLM/BFD RS for monitoring radio link or detecting beam failure,
- measure, upon reception of a target RLM/BFD RS, the RLM/BFD RS for monitoring radio link or detecting beam failure;
- and
- processing circuitry coupled with the interface circuitry, the processing circuitry configured to:
- compare at least one measurement result of the target RLM/BFD RS with a set of threshold values for an in-sync (IS)/out-of-sync (OOS) classification, and
- trigger an IS or OOS event based on the comparison of the at least one measurement result of the target RLM/BFD RS with the set of threshold values.
An access node (AN), comprising:
- radio front end circuitry;
- and
- processor circuitry coupled to the radio front end circuitry, and configured to:
- generate a radio link monitoring (RLM) or beam failure detection (BFD) reference signal (RS) configuration that indicates a target RLM/BFD RS for monitoring radio link or detecting beam failure;
- transmit the RLM/BFD RS configuration to a user equipment (UE);
- generate one or more tracking reference signal (TRS) configurations indicating one or more TRS;
- and
- transmit the one or more TRS configurations to the UE, wherein at least one of the one or more TRS is quasi co-located (QCLed) with the target RLM/BFD RS.
