A wireless device receives message(s) comprising configuration parameters of cells, a first IE for the primary PUCCH, a second IE indicating SR maximum number of transmissions, and an SR prohibit timer IE for an SR timer. The configuration parameters comprise: a primary cell with a PUCCH; and a PUCCH secondary cell with a secondary PUCCH. The first IE indicates the SR maximum number of transmissions. In response to an SR counter less than the SR maximum number of transmissions in a first SR subframe: the SR counter increments; a physical layer is instructed to signal an SR associated with an SR process on one valid PUCCH resource for the SR. The SR timer starts and is configured with an expiration duration value determined based on the SR prohibit timer IE regardless of which one of the primary PUCCH and the secondary PUCCH is employed for transmission of the SR.
