Abstract
A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The PUCCH groups comprise a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH. An adjustment factor is determined based on a first transmit power control (TPC) command for the secondary PUCCH. A value of the adjustment factor is stored in response to a deactivation of the PUCCH secondary cell. A second TPC command for the secondary PUCCH is received. The second TPC command is ignored based on the PUCCH secondary cell being in a deactivated state. After an activation of the PUCCH secondary cell, an uplink control information (UCI) is transmitted via the secondary PUCCH employing the stored value of the adjustment factor.
Claims20
A method comprising:
- receiving, by a wireless device, configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups comprising a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;
- determining an adjustment factor based on a first transmit power control (TPC) command for the secondary PUCCH;
- storing a value of the adjustment factor in response to a deactivation of the PUCCH secondary cell;
- receiving a second TPC command for the secondary PUCCH;
- ignoring the second TPC command based on the PUCCH secondary cell being in a deactivated state;
- and
- transmitting, after an activation of the PUCCH secondary cell, an uplink control information (UCI) via the secondary PUCCH employing the stored value of the adjustment factor.
