Scheduling request in a wireless device and wireless network
At least one message comprises a first information element (IE) for the primary physical uplink control channel (PUCCH), a second IE for the secondary PUCCH, and an SR prohibit timer IE. The first IE and the second IE indicate an SR maximum number of transmissions. A wireless device transmits an SR associated with an SR process and starts the SR timer with an initial value determined employing, at least, the SR prohibit timer IE. The wireless device cancels the SR process if the SR maximum number of transmissions is reached in a first SR subframe.

a second IE for the secondary PUCCH if SR resources are configured for the PUCCH secondary cell, the second IE indicating the SR maximum number of transmissions; and
an SR prohibit timer IE for an SR timer;
transmitting an SR associated with an SR process;
incrementing an SR counter by one when the SR is transmitted;
starting the SR timer with an initial value determined employing, at least, the SR prohibit timer IE regardless of which one of the primary PUCCH and the secondary PUCCH is employed for transmission of the SR; and
