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: Various communication systems may benefit from improved signaling. For example, certain communication systems may benefit from improved signaling before network access is revoked through a citizens broadband radio service. A method may include receiving at a network entity from a citizens broadband radio service device a warning message. The warning message may include a drop time after which communication between a network and a user equipment using the citizens broadband radio service will terminate. The method may also include triggering the performing of an action based on the warning message by the network before the drop time.

Abstract: A method and apparatus may include activating, by a network node, power of a global-positioning-system receiver or power of an active antenna of the global-positioning-system receiver. The apparatus uses the global-positioning-system receiver to perform synchronization of the apparatus. The method may include receiving at least one measurement, wherein the at least one measurement includes real-time, predictive, or historic data. The method may also include determining a holdover duration based on the at least one measurement. The holdover duration corresponds to a length of time where the power of the global-positioning-system receiver or the power of the active antenna is to be turned off. The method may also include deactivating the power of the global-positioning-system receiver or the power of the active antenna for the holdover duration.
