Abstract
A plurality of physical uplink control channel (PUCCH) groups comprise a primary PUCCH group comprising a primary cell and a secondary PUCCH group comprising a PUCCH secondary cell. The wireless device deactivates the PUCCH secondary cell after a deactivation condition for the PUCCH secondary cell is met. The wireless device stops transmission of channel state information for a first secondary cell in the secondary PUCCH group after deactivation of the PUCCH secondary cell. The wireless device stops transmission of positive acknowledgement and negative acknowledgement on the PUCCH secondary cell after deactivation of the PUCCH secondary cell.
Claims20
A method comprising:
- receiving, by a wireless device from a base station, at least one message comprising:
- configuration parameters of a plurality of cells comprising at least one secondary cell, the 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 the base station;
- and
- a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
- and
- a deactivation timer value for a deactivation timer of one or more secondary cells;
- deactivating the PUCCH secondary cell after a deactivation condition for the PUCCH secondary cell is met;
- stopping transmission of channel state information for a first secondary cell in the secondary PUCCH group after deactivation of the PUCCH secondary cell, wherein the first secondary cell is different from the PUCCH secondary cell;
- and
- stopping transmission of positive acknowledgement and negative acknowledgement on the PUCCH secondary cell after deactivation of the PUCCH secondary cell.
