Deactivation timer for a secondary cell with a control channel
A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The PUCCH groups comprise a secondary PUCCH group. The secondary PUCCH group comprises a PUCCH secondary cell with a secondary PUCCH. A deactivation timer of the PUCCH secondary cell is restarts in response to a physical downlink control channel (PDCCH) on any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment. The PUCCH secondary cell is deactivated in response to the deactivation timer expiring.
1. A method comprising:
receiving, by a wireless device, configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups comprising a secondary PUCCH group, the secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;
restarting a deactivation timer of the PUCCH secondary cell in response to a physical downlink control channel (PDCCH) on any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment; and
deactivating the PUCCH secondary cell in response to the deactivation timer expiring.
2. The method of claim 1 , further comprising maintaining configuration of PUCCH resources of the PUCCH secondary cell when the PUCCH secondary cell is deactivated.
3. The method of claim 2 , further comprising transmitting on the PUCCH secondary cell at least one of the following:
channel state information;
positive acknowledgement and negative acknowledgement; and
a scheduling request.
4. The method of claim 3 , further comprising receiving a mapping of each of a plurality of secondary cells to one of a primary PUCCH group or the secondary PUCCH group.
5. The method of claim 1 , further comprising receiving configuration parameters of PUCCH resources of the PUCCH secondary cell.
6. The method of claim 1 , further comprising receiving a mapping of each of a plurality of secondary cells to one of a primary PUCCH group or the secondary PUCCH group.
7. The method of claim 1 , further comprising transmitting on the PUCCH secondary cell at least one of the following:
channel state information;
positive acknowledgement and negative acknowledgement; and
a scheduling request.
8. The method of claim 1 , wherein cross carrier scheduling of a cell in a primary PUCCH group is only configurable for another cell in the primary PUCCH group.
9. The method of claim 1 , wherein cross carrier scheduling of a cell in the secondary PUCCH group is only configurable for another cell in the secondary PUCCH group.
10. The method of claim 1 , further comprising receiving a deactivation timer value for a deactivation timer.
11. A method comprising:
receiving, by a wireless device, configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups comprising a secondary PUCCH group, the secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;
restarting a deactivation timer of the PUCCH secondary cell in response to a physical downlink control channel on a cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment for any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group; and
deactivating the PUCCH secondary cell in response to the deactivation timer expiring.
12. The method of claim 11 , further comprising maintaining configuration of PUCCH resources of the PUCCH secondary cell when the PUCCH secondary cell is deactivated.
13. The method of claim 12 , further comprising transmitting on the PUCCH secondary cell at least one of the following:
channel state information;
positive acknowledgement and negative acknowledgement; and
a scheduling request.
14. The method of claim 13 , further comprising receiving a mapping of each of a plurality of secondary cells to one of a primary PUCCH group or the secondary PUCCH group.
15. The method of claim 11 , further comprising receiving configuration parameters of PUCCH resources of the PUCCH secondary cell.
16. The method of claim 11 , further comprising receiving a mapping of each of a plurality of secondary cells to one of a primary PUCCH group or the secondary PUCCH group.
17. The method of claim 11 , further comprising transmitting on the PUCCH secondary cell at least one of the following:
channel state information;
positive acknowledgement and negative acknowledgement; and
a scheduling request.
18. The method of claim 11 , wherein cross carrier scheduling of a cell in a primary PUCCH group is only configurable for another cell in the primary PUCCH group.
19. The method of claim 11 , wherein cross carrier scheduling of a cell in the secondary PUCCH group is only configurable for another cell in the secondary PUCCH group.
20. The method of claim 11 , further comprising receiving a deactivation timer value for a deactivation timer.
