Deactivation of PUCCH secondary cell in PUCCH group
A base station transmits, to a wireless device, a configuration of a physical uplink control channel (PUCCH) group including a first secondary cell with a secondary PUCCH, and a second secondary cell. The base station transmits, in a first subframe, a media access control command including a bitmap indicating deactivation of the first secondary cell. In response to the deactivation of the first secondary cell, reception of channel state information for the second secondary cell is stopped in a second subframe that is eight subframes after the first subframe and stopping the reception does not occur before the second subframe.
1. 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 a configuration of a physical uplink control channel (PUCCH) group comprising:

a second secondary cell;
receive, in a first subframe, a media access control (MAC) command comprising a bitmap indicating deactivation of the first secondary cell; and
stop, in response to the deactivation of the first secondary cell, transmission of channel state information for the second secondary cell in a second subframe that is eight subframes after the first subframe, wherein the stopping does not occur before the second subframe.
2. The wireless device of claim 1 , wherein to receive the configuration, the instructions, when executed by the one or more processors, further cause the wireless device to receive configurations of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH; and
a secondary PUCCH group comprising the PUCCH group.
3. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to stop a monitoring of a downlink control channel of the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
4. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to stop a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
5. The wireless device of claim 1 , wherein the configuration comprises dedicated parameters comprising a deactivation timer parameter.
6. The wireless device of claim 1 , wherein the bitmap, in the MAC command, further indicates a deactivation of the second secondary cell.
7. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to stop uplink transmission on the second secondary cell before stopping uplink transmission on the first secondary cell.
8. A method comprising:
transmitting, by a base station to a wireless device, a configuration of a physical uplink control channel (PUCCH) group comprising:
a first secondary cell with a secondary PUCCH; and
a second secondary cell;
transmitting, in a first subframe, a media access control (MAC) command comprising a bitmap indicating deactivation of the first secondary cell; and
stopping, in response to the deactivation of the first secondary cell, reception of channel state information for the second secondary cell in a second subframe that is eight subframes after the first subframe, wherein the stopping does not occur before the second subframe.
9. The method of claim 8 , wherein the transmitting the configuration comprises transmitting configurations of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH; and
a secondary PUCCH group comprising the PUCCH group.
10. The method of claim 8 , further comprising stopping transmission of a downlink control channel of the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
11. The method of claim 8 , further comprising stopping, for the wireless device, a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
12. The method of claim 8 , wherein the configuration comprises dedicated parameters comprising a deactivation timer parameter.
13. The method of claim 8 , wherein the bitmap, in the MAC command, further indicates a deactivation of the second secondary cell.
14. The method of claim 8 , further comprising stopping uplink reception, from the wireless device, on the second secondary cell before stopping uplink reception, from the wireless device, on the first secondary cell.
15. 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, a configuration of a physical uplink control channel (PUCCH) group comprising:
a first secondary cell with a secondary PUCCH; and
a second secondary cell;
transmit, in a first subframe, a media access control (MAC) command comprising a bitmap indicating deactivation of the first secondary cell; and
stop, in response to the deactivation of the first secondary cell, reception of channel state information for the second secondary cell in a second subframe that is eight subframes after the first subframe, wherein the stopping does not occur before the second subframe.
16. The base station of claim 15 , wherein to transmit the configuration, the instructions, when executed by the one or more processors, further cause the base station to transmit configurations of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH; and
a secondary PUCCH group comprising the PUCCH group.
17. The base station of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the base station to stop transmission of a downlink control channel of the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
18. The base station of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the base station to stop, for the wireless device, a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
