DEVICES AND METHODS FOR D2D COMMUNICATION

摘要

The invention relates to a communication device (103a-c) configured to perform a device to device communication with a plurality of further communication devices (101a-c, 103a-c) using a second frequency band, wherein the communication device (103a-c) is configured to receive a control message from a further communication device (101a-c) of the plurality of communication devices (101a-c, 103a-c), the control message indicating that the further communication device (101a-c) is within a coverage area (301) of a cellular communication network (102); and wherein the communication device (103a-c) is further configured to, upon reception of said control message, start listening for messages from further communication devices of the plurality of communication devices (101a-c, 103a-c) using a first frequency band.
