15. A method of searching for a cell of a cellular communication network to camp on, the method comprising:
-
detecting, at a wireless interface of a user equipment, a device-to-device signal from a further user equipment, and performing a cell search procedure by the user equipment based on the detected device-to-device signal, the cell search procedure comprising scanning for signals from a base station of the cell in resources which are selected as a function of the device-to-device signal received from the further user equipment, wherein the user equipment prioritizes, based on the device-to-device signal received from the further user equipment, frequencies or times at which the user equipment searches for the signals from the base station. - View Dependent Claims (16, 17, 18, 19)
