Wireless communication method, base station and wireless communication device

A method of performing a wireless communication by a communication device, the method comprising:

• receiving a control signaling from a base station, the control signaling allocating a carrier for device-to-device direct communication;
• and
• performing the device-to-device direct communication with an object communication device using the allocated carrier,
• wherein the carrier for the device-to-device direct communication comprises carrier for the device-to-device direct communication allocated from conventional carrier, stand-alone new-type carrier and non-stand-alone new-type carrier, wherein the new-type carriers have a reduced number of control channels as compared with the conventional carrier, control signaling being transmitted using the conventional carrier for the device-to-device direct communication, and data transmission being performed using the non-stand-alone new-type carrier for the device-to-device direct communication.

A base station, comprising:

• circuitry including a processor and a memory, the circuitry configured to:
• determine whether communication devices which are to perform communication satisfy a condition for device-to-device direct communication, and
• in case that the condition is satisfied, transmit a control signaling to the communication devices, the control signaling allocating a carrier for the device-to-device direct communication,
• wherein the carrier for the device-to-device direct communication comprises carrier for the device-to-device direct communication allocated from conventional carrier, stand-alone new-type carrier and non-stand-alone new-type carrier, wherein the new-type carriers have a reduced number of control channels as compared with the conventional carrier, control signaling being transmitted using the conventional carrier for the device-to-device direct communication, and data transmission being performed using the non-stand-alone new-type carrier for the device-to-device direct communication.
