Configuration of secondary control channel group by base station

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit, to a wireless device, configuration parameters of cells grouped in:
• a secondary physical uplink control channel (PUCCH) group comprising:
• a PUCCH secondary cell with a secondary PUCCH;
• and
• a first secondary cell;
• and
• a primary PUCCH group comprising:
• a primary cell with a primary PUCCH;
• and
• a second secondary cell;
• transmit, during a first time interval, a command indicating activation of the first secondary cell and the second secondary cell;
• start reception of channel state information, from the wireless device, of the second secondary cell from a second time interval that is pre-determined number of time intervals after the first time interval;
• and
• start reception of channel state information, from the wireless device, of the first secondary cell from a third time interval that is a positive number plus the pre-determined number of time intervals after the first time interval,
• wherein, in response to activation of the PUCCH secondary cell being completed in or after the pre-determined number of time intervals after the first time interval, the positive number is based on when the activation of the PUCCH secondary cell is completed by the wireless device.
