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 comprising;
a primary cell with a primary physical uplink control channel (PUCCH) transmitted to the base station; and
a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
in response to a media access control (MAC) entity, of the wireless device, having more than one valid PUCCH resource for a scheduling request in a subframe, selecting, by the MAC entity of the wireless device, one of the primary PUCCH and the secondary PUCCH as a selected valid PUCCH resource for a scheduling request to transmit a scheduling request signal to the base station via the subframe;
instructing a physical layer, by the MAC entity, to transmit the scheduling request signal on the selected valid PUCCH resource for the scheduling request via the subframe; and
transmitting, by the physical layer to the base station, the scheduling request signal via the selected valid PUCCH resource of the subframe.

Abstract
A plurality of cells comprise a primary cell with a primary physical uplink control channel (PUCCH) and a PUCCH secondary cell with a secondary PUCCH. The wireless device transmits a scheduling request on one valid PUCCH resource for a scheduling request resource in a subframe. The wireless device selects one of the primary PUCCH and the secondary PUCCH as the one valid PUCCH resource for transmitting the scheduling request in the subframe when the wireless device has more than the one valid PUCCH resource for the scheduling request in the subframe.

10. 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 primary physical uplink control channel (PUCCH) and a secondary PUCCH; and as long as one scheduling request is pending, for each subframe in a plurality of subframes;
if no uplink shared channel resources are available for a transmission in the subframe and if a media access control (MAC) entity, of the wireless device, has at least one valid PUCCH resource for scheduling request configured for the subframe and if the subframe is not part of a measurement gap and if a scheduling request timer is not running and if a scheduling request counter is less than a configured value;increment the scheduling request counter by one; in response to the media access control (MAC) entity having more than one valid PUCCH resource for the scheduling request in a subframe, select, by the MAC entity of the wireless device, one of the primary PUCCH and the secondary PUCCH as a selected valid PUCCH resource for a scheduling request to transmit a scheduling request signal to a base station via the subframe; instruct a physical layer, by the MAC entity, to transmit the scheduling request signal on the selected valid PUCCH resource for the scheduling request via the subframe; and transmit, by the physical layer to the base station, the scheduling request signal via the selected valid PUCCH resource of the subframe. - View Dependent Claims (11, 12, 13, 14, 15)
