Abstract: Various communication systems may benefit from improved radio frequency transmissions. For example, communication systems may benefit from the selection of a frequency band based on measurements of a spectrum surrounding the user equipment. A method, in certain embodiments, may include taking measurements by a base station of a spectrum of an environment surrounding a user equipment. The method may also include determining based on the measurements and radio frequency capabilities of the base station at least one desired frequency for transmission by the user equipment. In addition, the method may include sending a request from the base station to a network entity requesting a grant of the at least one desired frequency for transmission by the user equipment.

Abstract: Systems and techniques for configuring a wireless base station. A wireless base station enters a configuration mode including less than full cellular functionality, receives neighboring cell information at least one neighbor cell in the vicinity of the wireless base station using communications requiring less than full cellular functionality by the wireless base station, and entering an operational mode including full cellular functionality, using a configuration based at least in part on the neighboring cell information.
