Abstract
Systems, apparatuses, methods, and computer-readable media are provided for radio link monitoring (RLM) evaluation period and layer 1 (L1) indication interval enhancements. A user equipment (UE) uses a scaling factor to scale the RLM evaluation period and/or the L1 indication interval. Different scaling factors may be used for different scenarios, conditions, or criteria. The same or different scaling factors may be used for the RLM evaluation period and the L1 indication interval. The scaling factor or a scaling factor index may be signaled to the UE by higher layer signaling. Other embodiments may be described and/or claimed.
Claims25
A user equipment (UE) comprising:
- a radio front end circuitry;
- and
- a baseband circuitry coupled to the radio front end circuitry, the baseband circuitry configured to:
- determine, based on a received configuration, one or more Radio Link Monitoring Reference Signal (RLM-RS) resources;
- determine a scaling factor to be used to scale a Radio Link Monitoring (RLM) evaluation period;
- monitor the one or more RLM-RS resources;
- and
- estimate a downlink (DL) radio link quality on the monitored RLS-RS resources over the scaled RLM evaluation period.
(canceled)
(canceled)
A non-transitory computer-readable storage media (CRSM) comprising instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to perform operations, the operations comprising:
- determining, based on a received configuration, one or more Radio Link Monitoring Reference Signal (RLS-RS) resources;
- determining a scaling factor to be used to scale an RLM layer 1 (L1) indication interval;
- monitor the one or more RLM-RS resources;
- and
- estimating a downlink (DL) radio link quality on the monitored RLS-RS resources over an RLM evaluation period;
- and
- sending, from a L1 entity to a higher layer entity, an L1 indication based on the estimated DL radio link quality after the scaled L1 indication interval.
(canceled)

(canceled)
A base station (BS) comprising:
- processing circuitry configured to:
- generate a configuration to indicate one or more Radio Link Monitoring Reference Signal (RLM-RS), resources on which downlink (DL) radio link quality is to be estimated, and an indication of a scaling factor to be used for the DL radio link quality estimation;
- and
- signal the configuration to a user equipment (UE).
