ENHANCED REPORTING FOR HANDOVER IN DEVICE-TO-DEVICE COMMUNICATION

摘要

A method, user equipment and a base station for handover in device-to-device communication are disclosed. To maintain continuity of the ongoing device-to-device communication after the handover, an enhanced reporting mechanism is introduced such that the user equipment with the ongoing device-to-device communication would be handed over to a cell of a neighbor base station that supports the device-to-device communication. In this manner, the device-to-device communication continuity may be maintained.

主权项

1. A method for performing a handover in device-to-device communication, comprising:
receiving, at a serving base station, a device-to-device support status report from at least one user equipment with ongoing device-to-device communication or from at least one neighbor base station, wherein the device-to-device support status report indicates support status of each of one or more cells of the at least one neighbor base station with respect to the device-to-device communication; determining, based on the device-to-device support status report and a measurement report received from the at least one user equipment, one or more candidate cells that support the device-to-device communication from the one or more cells of the at least one neighbor base station; and transmitting, one or more handover requests respectively corresponding to the one or more candidate cells, to the at least one neighbor base station for the handover of the at least one user equipment to one of the one or more candidate cells.
