METHOD AND APPARATUS FOR DEVICE TO DEVICE DIRECT COMMUNICATION IN CLOUD BASE STATION SYSTEM

摘要

Disclosed are a D2D direct communication method and apparatus in a cloud base station system. The present invention includes receiving a measurement result, including information about D2D proximity or interference from other devices, from each of a first device and a second device, determining whether or not to admit D2D direct communication between the first device and the second device based on the measurement results, sending radio resource information to a second base station and receiving radio resource information of the second base station if it is determined that the D2D direct communication is admitted, negotiating radio resources, allocated for the D2D direct communication, with the second base station using the internal primitive, and allocating radio resources to the first device based on the negotiation.

主权项

1. A method of a first base station performing handover in a cloud base station system, the method comprising:
receiving a measurement result for determining whether or not handover is necessary or a measurement result regarding Device-to-Device (D2D) proximity from a device; recognizes that the device moves to a cell boundary of a second base station; requesting the handover of the device from the second base station using an internal primitive; receiving an admission of the handover for the device from the second base station using the internal primitive; and sending a handover command to the device.
