Abstract
A wireless device receives a media access control (MAC) activation command indicating activation of a plurality of physical uplink control channel (PUCCH) secondary cell. The wireless device receives, on a secondary cell in the plurality of cells, downlink control information comprising a PUCCH transmit power control (TPC) command. The wireless device calculates, a transmit power of the secondary PUCCH, employing the PUCCH TPC command only if the secondary PUCCH group comprises the secondary cell. The wireless device transmits uplink signals on the secondary PUCCH with the transmit power.
Claims20
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;
- receiving a media access control (MAC) activation command indicating activation of the PUCCH secondary cell;
- receiving, on a secondary cell in the plurality of cells, downlink control information comprising a PUCCH transmit power control (TPC) command;
- calculating, a transmit power of the secondary PUCCH, employing the PUCCH TPC command only if the secondary PUCCH group comprises the secondary cell;
- and
- transmitting uplink signals on the secondary PUCCH with the transmit power.
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 transmitted to a base station;
- and
- a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
- receiving, on a secondary cell in the plurality of cells, downlink control information comprising a PUCCH transmit power control (TPC) command;
- calculating, a first transmit power of the primary PUCCH, employing the PUCCH TPC command if the primary PUCCH group comprises the secondary cell;
- calculating, a second transmit power of the secondary PUCCH, employing the PUCCH TPC command if the secondary PUCCH group comprises the secondary cell;
- and
- transmitting first uplink signals on the primary PUCCH with the first transmit power or second uplink signals on the secondary PUCCH with the second transmit power.
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 transmitted to a base station;
- and
- a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
- receiving, on a secondary cell in the plurality of cells, downlink control information comprising a PUCCH transmit power control (TPC) command;
- and
- applying the TPC command to:
- a first transmit power of the primary PUCCH if the secondary cell is mapped to the primary PUCCH group;
- and
- a second transmit power of the secondary PUCCH if the secondary cell is mapped to the secondary PUCCH group.
