PUCCH secondary cell deactivation in a wireless device
A wireless device receives a configuration of a physical uplink control channel (PUCCH) group. The PUCCH group comprises a PUCCH secondary cell with a secondary PUCCH and a secondary cell. A command indicating deactivation of the PUCCH secondary cell is received in a first subframe. In response to the deactivation of the PUCCH secondary cell, transmission of channel state information for the secondary cell in a second subframe that is eight subframes after the first subframe is stopped. Thee stopping does not occur before the second subframe.
1. A method comprising:
receiving, by 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;
receiving, 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, 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 method of claim 1 , wherein the receiving the configuration comprises receiving configurations of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH; and
a secondary PUCCH group.
3. The method of claim 2 , further comprising stopping 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 method of claim 2 , further comprising stopping 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 method of claim 1 , further comprising stopping 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.
6. The method of claim 1 , further comprising stopping a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
7. The method of claim 1 , wherein the configuration comprises dedicated parameters comprising a deactivation timer parameter.
8. The method of claim 1 , wherein the MAC command further indicates a deactivation of the second secondary cell.
9. The method of claim 1 , further comprising stopping uplink transmission on the second secondary cell before stopping uplink transmission on the first PUCCH secondary cell.
10. A method comprising:
receiving, by 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;
receiving, in a first subframe, a media access control (MAC) command comprising a bitmap indicating deactivation of the first secondary cell and the second secondary cell;
stopping uplink transmission via the first secondary cell on, and not before, a second subframe that is eight subframes after the first subframe; and
stopping uplink transmission via the second secondary cell before the second subframe that is eight subframes after the first subframe.
11. The method of claim 10 , wherein the receiving the configuration comprises receiving configurations of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH; and
a secondary PUCCH group.
12. The method of claim 11 , further comprising stopping 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.
13. The method of claim 11 , further comprising stopping a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
14. The method of claim 10 , further comprising stopping 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.
15. The method of claim 10 , further comprising stopping a deactivation timer associated with the second secondary cell on or before the second subframe that is eight subframes after the first subframe.
16. The method of claim 10 , wherein the configuration comprises dedicated parameters comprising a deactivation timer parameter.
17. The method of claim 10 , wherein the stopping uplink transmission via the second secondary cell is before the stopping uplink transmission via the first secondary cell.
18. The method of claim 10 , wherein a deactivation timer of the first secondary cell is disabled.
