Abstract
A wireless device receives at least one message comprising configuration parameters of a plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising: a primary PUCCH group comprising a primary cell with a primary PUCCH, and a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH. The wireless device receives, on a common search space of the primary cell, a transmit power control (TPC) command for the secondary PUCCH. The wireless device ignores the TPC command when the PUCCH secondary cell is in a deactivated state.
Claims14
A method comprising:
- receiving, by a wireless device, at least one message comprising configuration parameters of a plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising:
- a primary PUCCH group comprising a primary cell with a primary PUCCH;
- and
- a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;
- transmitting first uplink control information (UCI) on the secondary PUCCH employing an adjustment factor, wherein the adjustment factor is updated in response to the wireless device receiving at least one first transmit power control (TPC) command for the secondary PUCCH;
- receiving a first media access control (MAC) command indicating deactivation of the PUCCH secondary cell;
- in response to the deactivation of the PUCCH secondary cell, storing a value of the adjustment factor;
- receiving, on a common search space of the primary cell, at least one second TPC command for the secondary PUCCH;
- ignoring the at least one second TPC command for the secondary PUCCH when the PUCCH secondary cell is in a deactivated state;
- receiving a second MAC command indicating activation of the PUCCH secondary cell;
- and
- after the activation of the PUCCH secondary cell, transmitting a second UCI on the secondary PUCCH employing the stored value of the adjustment factor.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive at least one message comprising configuration parameters of a plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising:
- a primary PUCCH group comprising a primary cell with a primary PUCCH;
- and
- a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;
- transmit first uplink control information (UCI) on the secondary PUCCH employing an adjustment factor, wherein the adjustment factor is updated in response to the wireless device receiving at least one first transmit power control (TPC) command for the secondary PUCCH;
- receive a first media access control (MAC) command indicating deactivation of the PUCCH secondary cell;
- in response to the deactivation of the PUCCH secondary cell, store a value of the adjustment factor;
- receive, on a common search space of the primary cell, at least one second TPC command of the secondary PUCCH;
- ignore the at least one second TPC command for the secondary PUCCH when the PUCCH secondary cell is in a deactivated state;
- receive a second MAC command indicating activation of the PUCCH secondary cell;
- and
- after the activation of the PUCCH secondary cell, transmit a second UCI on the secondary PUCCH employing the stored value of the adjustment factor.
