Abstract: A wireless communication device, a wireless communication method, and a base station, the wireless communication device being used for device-to-device communication and including: a reception device, used for receiving paging signaling sent when in communication with another wireless communication device and preset conditions are satisfied for device-to-device communication, the paging signaling being used to supplement paging between the wireless communication device and the other wireless-communication device; paging based upon the paging signaling is used to confirm establishment of device-to-device communication between the wireless communication device and the other wireless-communication device. The wireless communication device, wireless communication method, and base station at least can enhance efficiency of device-to-device paging and thus also enhance efficiency of device-to-device communication.

Abstract: A wireless communication method, a base station and a wireless communication device. The wireless communication method includes: in case that communication devices which are to perform communication are estimated to satisfy a condition for device-to-device direct communication, transmitting a control signaling from a base station to the communication devices, the control signaling allocating a carrier for the device-to-device direct communication; and performing the device-to-device direct communication between the communication devices using the allocated carrier, wherein the base station allocates the carrier for the device-to-device direct communication from conventional carrier, stand-alone new-type carrier and non-stand-alone new-type carrier, wherein the new-type carrier has a reduced number of control channels as compared with the conventional carrier.
