Abstract
Wireless communications using multiple active resources (e.g., bandwidth parts (BWPs)) are described. A wireless device may perform failure event detection, such as radio link monitoring (RLM) and/or beam failure detection (BFD), jointly or separately for multiple active resources (e.g., BWPs) based on one or more criteria.
Claims21
A method comprising:
- activating, by a wireless device, at least two downlink bandwidth parts (BWPs) for a cell;
- determining, for beam failure detection, radio link quality of one or more reference signals associated with a first downlink BWP of the at least two downlink BWPs;
- and
- sending, based on the radio link quality of the one or more reference signals, a signal indicating a beam failure for the at least two downlink BWPs.
1 more element
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- activate at least two downlink bandwidth parts (BWPs) for a cell;
- determine, for beam failure detection, radio link quality of one or more reference signals associated with a first downlink BWP of the at least two downlink BWPs;
- and
- send, based on the radio link quality of the one or more reference signals, a signal indicating a beam failure for the at least two downlink BWPs.
4 more elements
One or more non-transitory computer-readable media storing instructions that, when executed, configure a wireless device to:
- activate at least two downlink bandwidth parts (BWPs) for a cell;
- determine, for beam failure detection, radio link quality of one or more reference signals associated with a first downlink BWP of the at least two downlink BWPs;
- and
- send, based on the radio link quality of the one or more reference signals, a signal indicating a beam failure for the at least two downlink BWPs.
