Cell Grouping in Beam Failure Recovery Procedure

A base station comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the base station to:
• restart a deactivation timer of a first secondary cell configured with one or more beam failure recovery (BFR) parameters in response to transmitting, to a wireless device, a physical downlink control channel indicating an uplink grant or a downlink assignment for any secondary cell, other than the first secondary cell, in a cell group of secondary cells comprising:
• the first secondary cell;
• and
• one or more further secondary cells configured to use the first secondary cell for a BFR procedure of the cell group;
• and
• deactivate the first secondary cell based on an expiry of the deactivation timer of the first secondary cell.

A system comprising:

• a wireless device;
• and
• a base station comprising one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the base station to:
• restart a deactivation timer of a first secondary cell configured with one or more beam failure recovery (BRF) parameters in response to transmitting, to the wireless device, a physical downlink control channel indicating an uplink grant or a downlink assignment for any secondary cell, other than the first secondary cell, in a cell group of secondary cells comprising:
• the first secondary cell;
• and
• one or more further secondary cells configured to use the first secondary cell for a BFR procedure of the cell group;
• and
• deactivate the first secondary cell based on an expiry of the deactivation timer of the first secondary cell.
