Abstract
Systems, apparatuses, and methods are described for wireless communications. A base station may configure a plurality of random access configurations for a wireless device on different uplink carriers, such as a supplemental uplink carrier and a non-supplemental uplink carrier. The wireless device may fall back to a second uplink carrier if a random access procedure fails on the first uplink carrier.
