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: Various communication systems may benefit from improved wireless communications. For example, communication systems may benefit from a wireless broadband network that monitors and detects link latency. A method includes detecting latency information of data being transmitted on at least one link between a first base station and at least one second base station. In addition, the method includes forming at least one array comprising the latency information of the data. Further, the method includes modifying a system behavior relating to at least the first base station or the at least one second base station based on the at least one array.

Abstract: There is provided a method comprising determining a first subset of cells served by a first base station to be suitable for handover to a user equipment associated with a second base station, the subset comprising at least one but not all of the cells served by the first base station and providing information to the second base station from the first base station, said information comprising an indication of the determined first subset of cells
