1. A method comprising:
- receiving, by a wireless device, configuration parameters of a plurality of cells comprising;
a primary cell that is not configured with scheduling request (SR) resources; and
a secondary cell that is configured with the SR resources and that is in a secondary timing advance group (sTAG);
transmitting, via the SR resources, an SR associated with an SR process;
initiating a random access procedure based on;
the SR process being pending in a subframe;
no uplink data channel resource being available for transmission in the subframe; and
a time alignment timer associated with the sTAG not running in the subframe; and
transmitting, by the wireless device, a random access preamble.

Abstract
A wireless device may receive configuration parameters of cells comprising a primary cell with no configured scheduling request (SR) resources and a secondary cell in an sTAG and with configured SR resources. An SR associated with an SR process may be transmitted in the SR resources. A random access procedure may be initiated in response to: the SR process pending in a subframe; no uplink data channel resource available for transmission in the subframe; and a time alignment timer of the sTAG not running in the subframe. A random access preamble may be transmitted by the wireless device.
