Particularly, the present invention discloses a method for performing radio link monitoring by a user equipment when a base station supports at least one beam and device for supporting the same.
Claims10
A method for performing radio link monitoring (RLM) by a user equipment (UE) in a wireless communication system, the method comprising:
- assessing radio link quality for each of a plurality of resources,
- wherein the radio link quality for each of the plurality of resources is assessed based on a reference signal received via each of the plurality of resources,
- wherein the reference signal received via each of the plurality of resources comprises a synchronization signal/physical broadcast channel (SS/PBCH) block or a channel state information reference signal (CSI-RS),
- wherein the SS/PBCH block comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH);
- and
- based on that the radio link quality for each of the plurality of resources is lower than a threshold, transmitting a signal corresponding to ‘Out-of-Sync’ to a higher layer,
- wherein the radio link quality for each of the plurality of resources is assessed, based on the threshold being one of a first threshold for the SS/PBCH block or a second threshold for the CSI-RS according to whether the reference signal received via each of the plurality of resources is the SS/PBCH block or the CSI-RS.
A user equipment (UE) for performing radio link monitoring (RLM) in a wireless communication system, the UE comprising:
- a receiver;
- and
- a processor connected to the receiver,
- wherein the processor is configured to:
- assess radio link quality for each of a plurality of resources,
- wherein the radio link quality for each of the plurality of resources is assessed based on a reference signal received via each of the plurality of resources,
- wherein the reference signal received via each of the plurality of resources comprises a synchronization signal/physical broadcast channel (SS/PBCH) block or a channel state information reference signal (CSI-RS),
- wherein the SS/PBCH block comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH);
- and
- based on that the radio link quality for each of the plurality of resources is lower than a threshold, transmit a signal corresponding to ‘Out-of-Sync’ to a higher layer,
- wherein the radio link quality for each of the plurality of resources is assessed, based on the threshold being one of a first threshold for the SS/PBCH block or a second threshold for the CSI-RS according to whether the reference signal received via each of the plurality of resources is the SS/PBCH block or the CSI-RS.
