Device-To-Device Discovery and Operation

A method comprising:

• configuring by a network element a plurality of discovery channels, each discovery channel of the plurality of the discovery channels being mapped to one control channel;
• receiving by the network element an indication from a device about detecting a device-to-device discovery signal on one discovery channel of the plurality of discovery channels;
• and
• transmitting by the network element information on a control channel mapped from the one discovery channel, the information comprising a resource allocation for device-to-device communications.

An apparatus comprising:

• at least one processor and a memory storing a set of computer instructions, in which the processor and the memory storing the computer instructions are configured to cause the apparatus to:
• transmit or receiving by a first device a device-to-device discovery signal on a discovery channel;
• map the discovery channel to one control channel;
• and
• monitor the one control channel for information comprising a resource allocation for device-to-device communications.
