1. A method comprising:
- receiving, by a wireless device from a base station, at least one message comprising configuration parameters of a plurality of cells, 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;
receiving, in a first subframe, a media access control (MAC) command indicating deactivation of the PUCCH secondary cell; and
stopping, in response to the deactivation of the PUCCH secondary cell, transmission of channel state information for a first secondary cell in the secondary PUCCH group in a second subframe that is eight subframes after the first subframe, wherein the first secondary cell is different from the PUCCH secondary cell and the stopping does not occur before the second subframe.

Abstract
A wireless device receives at least one message comprising configuration parameters of a plurality of cells. The plurality of cells are grouped into a plurality of physical uplink control channel (PUCCH) groups comprising a primary PUCCH group and a secondary PUCCH group comprising a PUCCH secondary cell. The wireless device receives, in subframe n, a media access control (MAC) command indicating deactivation of the PUCCH secondary cell. The wireless device stops transmission of channel state information for a first secondary cell in the secondary PUCCH group in subframe n+8.

8. A method comprising:
-
receiving, by a wireless device from a base station, at least one message comprising configuration parameters of a plurality of cells, 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; receiving, in a first subframe, a media access control (MAC) command indicating deactivation of a first secondary cell and the PUCCH secondary cell; stopping uplink transmission via the PUCCH secondary cell on, and not before, a second subframe that is eight subframes after the first subframe; and stopping uplink transmission via the first secondary cell before the second subframe that is eight subframes after the first subframe. - View Dependent Claims (9, 10, 11, 12, 13)

14. 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, from a base station, at least one message comprising configuration parameters of a plurality of cells, the plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising; a primary PUCCH group corn prising 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; receive, in a first subframe, a media access control (MAC) command indicating deactivation of the PUCCH secondary cell; and stop, in response to the deactivation of the PUCCH secondary cell, transmission of channel state information for a first secondary cell in the secondary PUCCH group in a second subframe that is eight subframes after the first subframe, wherein the first secondary cell is different from the PUCCH secondary cell and the stopping does not occur before the second subframe. - View Dependent Claims (15, 16, 17, 18, 19, 20)
