Abstract
Methods are proposed for UE to perform radio link monitoring (RLM) and beam failure detection (BFD) measurements in a relaxed measurement state with an extended evaluation period for power saving. Different criteria for UE to enter and exit the relaxed RLM/BFD measurement state are proposed. In relaxed measurement state, UE can perform RLM/BFD measurements with an extended evaluation period by a scaling factor K when the serving cell quality is higher than a threshold and/or when the serving cell quality variation is lower than a threshold within a time period.
Claims22
A method comprising:
- receiving configuration information of a plurality of reference signals for performing radio link monitoring (RLM) and beam failure discovery (BFD) measurements by a user equipment (UE) in a new radio (NR) network;
- determining whether the UE satisfies criteria for entering a relaxed RLM/BFD measurement state, wherein the criteria comprises at least one of a serving cell quality criteria, and a UE mobility criteria during a period of time;
- and
- entering the relaxed RLM/BFD measurement state and performing RLM/BFD measurements with a scaling factor K and an extended evaluation period upon satisfying the criteria.
A User Equipment (UE) comprising:
- a receiver that receives configuration information of a plurality of reference signals for performing radio link monitoring (RLM) and beam failure discovery (BFD) measurements in a new radio (NR) network;
- a control circuit that determines whether the UE satisfies criteria for entering a relaxed RLM/BFD measurement state, wherein the criteria comprises at least one of a serving cell quality criteria, and a UE mobility criteria during a period of time;
- and
- a measurement handling circuit that enters the relaxed RLM/BFD measurement state and performs RLM/BFD measurements with a scaling factor K and an extended evaluation period upon satisfying the criteria.
