1. A method for a wireless device comprising:
- identifying a pilot signal of a base station in a frequency division duplex wireless system;
obtaining a reverse access channel identifier and a forward signaling channel identifier from the pilot signal;
initiating communication with the base station via a reverse access channel corresponding to the reverse access channel identifier;
sensing a set of candidate channels available for use by the wireless device; and
reporting the set of candidate channels to the base station.

Abstract
The present disclosure relates generally to systems and methods for pilot signal utilization in an environment using dynamic frequency assignment. In one example, a method for a wireless device includes identifying a pilot signal of a base station in a frequency division duplex wireless system. A reverse access channel identifier and a forward signaling channel identifier are obtained from the pilot signal and communication is initiated with the base station via the reverse access channel. A set of candidate channels available for use by the wireless device is sensed and reported to the base station.
