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, configuration parameters of a cell, wherein the cell comprises a first bandwidth part (BWP) and a second BWP;
- activating the first BWP and the second BWP;
- determining, based on a first downlink control channel configuration of the first BWP and a second downlink control channel configuration of the second BWP, a BWP, of the first BWP and the second BWP, for radio link monitoring for the cell;
- measuring, during a time period that the first BWP and the second BWP are active, one or more reference signals associated with the determined BWP;
- determining, based on the measuring, a radio link failure for the cell;
- and
- initiating, based on the radio link failure for the cell, a connection re-establishment procedure.

A method comprising:
- receiving, by a wireless device, configuration parameters for a first bandwidth part (BWP) of a cell and for a second BWP of the cell;
- activating the first BWP and the second BWP;
- determining, based on a first radio interface type associated with the first BWP and a second radio interface type associated with the second BWP, a BWP, of the first BWP and the second BWP, for radio link monitoring for the cell;
- measuring, during a time period that the first BWP and the second BWP are active, one or more reference signals associated with the determined BWP;
- determining, based on the measuring, a radio link failure for the cell;
- and
- sending, based on the radio link failure for the cell, a preamble associated with a random access procedure.

A method comprising:
- receiving, by a wireless device, configuration parameters for a first bandwidth part (BWP) of a cell and for a second BWP of the cell;
- activating the first BWP and the second BWP;
- determining, based on one or more criteria, a BWP for radio link monitoring for the cell, wherein the one or more criteria comprises at least one of:
- a first BWP index of the first BWP and a second BWP index of the second BWP;
- a first numerology index of the first BWP and a second numerology index of the second BWP;
- a first service type on the first BWP and a second service type on the second BWP;
- or
- a radio link monitoring reference signal configuration;
- measuring, during a time period that the first BWP and the second BWP are active, one or more reference signals associated with the determined BWP;
- determining, based on the measuring, a radio link failure for the cell;
- and
- sending, based on the radio link failure for the cell, a preamble associated with a random access procedure.
