Abstract
A method of a communication device configured for cellular communication and device-to-device, D2D, operation and operating in an out-of-coverage, OoC, state is disclosed. The method comprises determining whether a D2D operation is ongoing or imminent, performing cell search according to a first rate when no D2D operation is ongoing or imminent, and performing cell search according to a second rate when D2D operation is ongoing or imminent. A method is also disclosed where it is determined whether the communication device is in one of an OoC and IC state, and a cell search is adapted accordingly. A communication device and a network node, a method for a network node, and computer programs are also disclosed.
