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.
Claims20
A method comprising:
- receiving, by a wireless device, one or more configuration parameters of a cell;
- activating at least two downlink bandwidth parts (BWPs) of a plurality of downlink BWPs for the cell, wherein a set of one or more reference signals for beam failure detection is associated with a first downlink BWP of the plurality of downlink BWPs;
- measuring the set of the one or more reference signals associated with the first downlink BWP;
- and
- determining, based on the measuring, a beam failure for the at least two downlink BWPs.
2 more elements
A method comprising:
- receiving, by a wireless device, one or more configuration parameters for a first downlink bandwidth part (BWP) of a cell and for a second downlink BWP of the cell, wherein the one or more configuration parameters indicate:
- a first set of one or more reference signals for a beam failure detection associated with the first downlink BWP;
- and
- a second set of one or more reference signals for a beam failure detection associated with the second downlink BWP;
- activating the first downlink BWP and the second downlink BWP;
- measuring, based on the activating, the first set of one or more reference signals and the second set of one or more reference signals;
- and
- determining, based on the measuring, a beam failure for the cell.

A method comprising:
- receiving, by a wireless device, one or more configuration parameters for a first downlink bandwidth part (BWP) of a cell and for a second downlink BWP of the cell, wherein the one or more configuration parameters indicate:
- a first set of one or more reference signals for a beam failure detection associated with the first downlink BWP;
- and
- a second set of one or more reference signals for a beam failure detection associated with the second downlink BWP;
- activating the first downlink BWP and the second downlink BWP;
- and
- based on the activating, performing beam failure detection of the cell comprising:
- the beam failure detection associated with the first downlink BWP;
- and
- the beam failure detection associated the second downlink BWP;
- and
- determining, based on the beam failure detection of the cell, an instance of a beam failure for the cell.
