Abstract

A wireless device receives at least one message comprising configuration parameters of a 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, and a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH. The wireless device receives, on a common search space of the primary cell, a transmit power control (TPC) command for the secondary PUCCH. The wireless device ignores the TPC command when the PUCCH secondary cell is in a deactivated state.

Claims (48)

1. A method comprising:

receiving, by a wireless device, at least one message comprising configuration parameters of a 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; and

a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;

transmitting first uplink control information (UCI) on the secondary PUCCH employing an adjustment factor, wherein the adjustment factor is updated in response to the wireless device receiving at least one first transmit power control (TPC) command for the secondary PUCCH;

receiving a first media access control (MAC) command indicating deactivation of the PUCCH secondary cell;

in response to the deactivation of the PUCCH secondary cell, storing a value of the adjustment factor;

receiving, on a common search space of the primary cell, at least one second TPC command for the secondary PUCCH;

ignoring the at least one second TPC command for the secondary PUCCH when the PUCCH secondary cell is in a deactivated state;

receiving a second MAC command indicating activation of the PUCCH secondary cell; and

after the activation of the PUCCH secondary cell, transmitting a second UCI on the secondary PUCCH employing the stored value of the adjustment factor.

2. The method of claim 1 , further comprising

transmitting a first instance of UCI on the secondary PUCCH employing the adjustment factor with the value of the adjustment factor set to zero.

3. The method of claim 1 , further comprising

transmitting a first instance of UCI on the secondary PUCCH employing the adjustment factor with the value of the adjustment factor determined based on a transmit power control value received in a random access response.

4. The method of claim 1 , further comprising

ignoring all TPC commands for the secondary PUCCH that are received on the common search space of the primary cell when the PUCCH secondary cell is in the deactivated state.

5. The method of claim 1 , wherein the at least one message further comprises a pathloss reference parameter indicating a pathloss reference cell of the PUCCH secondary cell.

6. The method of claim 1 , further comprising

ignoring downlink control information for the secondary PUCCH that is received on the common search space when the PUCCH secondary cell is uplink out-of-sync.

7. The method of claim 1 , wherein downlink control information received on the common search space comprises:

the first TPC command for the secondary PUCCH; and

a first TPC command for the primary PUCCH.

8. 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 at least one message comprising configuration parameters of a 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; and

a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH;

transmit first uplink control information (UCI) on the secondary PUCCH employing an adjustment factor, wherein the adjustment factor is updated in response to the wireless device receiving at least one first transmit power control (TPC) command for the secondary PUCCH;

receive a first media access control (MAC) command indicating deactivation of the PUCCH secondary cell;

in response to the deactivation of the PUCCH secondary cell, store a value of the adjustment factor;

receive, on a common search space of the primary cell, at least one second TPC command of the secondary PUCCH;

ignore the at least one second TPC command for the secondary PUCCH when the PUCCH secondary cell is in a deactivated state;

receive a second MAC command indicating activation of the PUCCH secondary cell; and

after the activation of the PUCCH secondary cell, transmit a second UCI on the secondary PUCCH employing the stored value of the adjustment factor.

9. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to

transmit a first instance of UCI on the secondary PUCCH employing the adjustment factor with the value of the adjustment factor set to zero.

10. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to

transmit a first instance of UCI on the secondary PUCCH employing the adjustment factor with the value of the adjustment factor determined based on a transmit power control value received in a random access response.

11. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to

ignore all TPC commands for the secondary PUCCH that are received on the common search space of the primary cell when the PUCCH secondary cell is in the deactivated state.

12. The wireless device of claim 8 , wherein the at least one message further comprises a pathloss reference parameter indicating a pathloss reference cell of the PUCCH secondary cell.

13. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to

ignore downlink control information for the secondary PUCCH that is received on the common search space when the PUCCH secondary cell is uplink out-of-sync.

14. The wireless device of claim 8 , wherein downlink control information received on the common search space comprises:

the first TPC command for the secondary PUCCH; and

a first TPC command for the primary PUCCH.
