Abstract
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.
Claims20
A method for performing a handover during a device-to-device communication, comprising:
- receiving, at a serving base station, a device-to-device support status report from at least one user equipment involved in an ongoing device-to-device communication or from at least one neighbor base station, wherein the device-to-device support status report indicates which of one or more cells of the at least one neighbor base station support a device-to-device feature that will maintain continuity for 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 D2D feature that will maintain continuity for 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.

A base station, comprising:
- a receiver configured to receive a device-to-device support status report from at least one user equipment involved in an ongoing device-to-device communication or from at least one neighbor base station, wherein the device-to-device support status report indicates which of one or more cells of the at least one neighbor base station support a device-to-device feature that will maintain continuity for the device-to-device communication;
- a determining unit configured to determine, 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 feature that will maintain continuity for the device-to-device communication from the one or more cells of the at least one neighbor base station;
- and
- a transmitter configured to transmit, one or more handover requests respectively corresponding to the one or more candidate cells, to the neighbor base station for the handover of the at least one user equipment to one of the one or more candidate cells.
1 more element
A hardware storage medium containing computer-executable instructions comprising:
- computer-executable instructions to receive, at a serving base station, a device-to-device support status report from at least one user equipment involved in an ongoing device-to-device communication or from at least one neighbor base station, wherein the device-to-device support status report indicates which of one or more cells of the at least one neighbor base station support a device-to-device feature that will maintain continuity for to the device-to-device communication;
- computer-executable instructions to determine, 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 feature that will maintain continuity for the device-to-device communication from the one or more cells of the at least one neighbor base station;
- and
- computer-executable instructions to transmit 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.
