Abstract

A method for a first communication device adapted to perform cellular network assisted device- to -device communication is disclosed. A device -to- device communication cluster of a plurality of communication devices comprises the first communication device and one or more other communication devices and a specific one of the plurality of communication devices performs a network control signal gateway function for the device -to -device communication cluster. The network control signal gateway function comprises receiving downlink control signals from a network node of the cellular network ,transmitting uplink control signals to the network node of the cellular network , and operating control signaling within the device- to -device communication cluster in association with the downlink and uplink control signals. The method of the communication device comprises deciding whether or not to switch the network control signal gateway function from the specific communication device to another communication device in the plurality of communication devices. The decision is based on link quality measurements of prospect communication links between the network node and the specific communication device and between the network node and the another communication device and/or on link quality measurements of device- to- device communication links between the specific communication device and communication devices, other than the specific communication device , of the plurality of communication devices and between the another communication de communication devices , other than the another communication device , of vice and the plurality of communication devices. Corresponding computer program product , arrangement and communication device are also disclosed.
