Abstract
Wireless communications are described. A wireless device and/or a base station may provide improved resource management. A base station may configure and/or transmit a beam failure recovery medium access control control element (BFR MAC CE) to a wireless device to activate one or more beam failure reference signal resources for beam failure of a downlink bandwidth part (BWP) of a cell. The wireless device may assess, based on receiving the BFR MAC CE, a radio link quality of one or more reference signals for beam failure detection of the downlink BWP of the cell.
Claims20
A method comprising:
- receiving, by a wireless device, a first beam failure medium access control (MAC) control element (CE) that comprises a field indicating one or more first beam failure reference signal resources, wherein the first beam failure MAC CE is configured to activate the one or more first beam failure reference signal resources for beam failure of a downlink bandwidth part (BWP) of a cell;
- based on receiving the first beam failure MAC CE, assessing a radio link quality of one or more reference signals for beam failure detection of the downlink BWP of the cell;
- incrementing a beam failure instance counter for the cell;
- receiving a second beam failure MAC CE that comprises a field indicating one or more second beam failure reference signal resources, wherein the second beam failure MAC CE is configured to activate the one or more second beam failure reference signal resources for beam failure of the downlink BWP of the cell;
- and
- based on the receiving the second beam failure MAC CE, setting the beam failure instance counter to zero.
A method comprising:
- receiving, by a wireless device, a beam failure medium access control (MAC) control element (CE) comprising:
- a first field indicating a cell;
- a second field indicating a downlink bandwidth part (BWP) of the cell;
- and
- a third field indicating one or more beam failure reference signal resources, associated with one or more reference signals, for beam failure of the downlink BWP of the cell,
- wherein the beam failure MAC CE is configured to activate the one or more beam failure reference signal resources;
- and
- based on receiving the beam failure MAC CE, assessing a radio link quality of the one or more reference signals.
A method comprising:
- incrementing, by a wireless device, a beam failure instance counter based on a beam failure instance indication of a cell;
- receiving a beam failure medium access control (MAC) control element (CE) comprising:
- a first field indicating the cell;
- a second field indicating a downlink bandwidth part (BWP) of the cell;
- and
- a third field indicating one or more beam failure reference signal resources for beam failure of the downlink BWP of the cell,
- wherein the beam failure MAC CE is configured to activate the one or more beam failure reference signal resources;
- and
- based on the receiving the beam failure MAC CE, setting the beam failure instance counter to zero.
