Abstract
When a downlink bandwidth part (BWP) is switched from a first BWP to a second BWP without a change of a cell defining synchronization signal block (SSB), if a reference signal type for Radio Link Monitoring (RLM) is set to an SSB type, a radio terminal (12) continues to use for RLM measurements a first SSB associated with the first BWP after switching of the downlink BWP to the second BWP. This for example enables the radio terminal to monitor a suitable Reference Signal (RS) for RLM measurements after switching of the DL active BWP.
Claims18
A radio terminal comprising:
- a memory;
- and
- at least one processor connected to the memory,
- wherein the at least one processor is configured to;
- receive a first bandwidth part (BWP) configuration for a first BWP and a second BWP configuration for a second BWP, the first BWP including a cell defining synchronization signal block (SSB);
- switch an active downlink BWP from the first BWP to the second BWP;
- and
- continue to use, for Radio Link Monitoring (RLM) measurements, the cell defining SSB for the first BWP, if the active downlink BWP is the second BWP, if the downlink BWP is switched from the first BWP to the second BWP without a change of the cell defining SSB, and if a reference signal type for RLM is set to an SSB type.

A method of a radio terminal, the method comprising:
- receiving a first bandwidth part (BWP) configuration for a first BWP and a second BWP configuration for a second BWP, the first BWP including a cell defining synchronization signal block (SSB);
- switching an active downlink BWP from the first BWP to the second BWP;
- and
- continuing to use, for Radio Link Monitoring (RLM) measurements, the cell defining SSB for the first BWP, if the active downlink BWP is the second BWP, if the downlink BWP is switched from the first BWP to the second BWP without a change of the cell defining SSB, and if a reference signal type for RLM is set to an SSB type.
