US 2016/0081046 A1 · METHOD AND APPARATUS FOR RESOURCE SHARING FOR DEVICE-TO-DEVICE AND CELLULAR COMMUNICATIONS IN A MULTICELL NETWORK

Abstract

Embodiments of the disclosure provide a method and apparatus for resource sharing for D2D and cellular communications in a multicell network. The method comprises steps of: acquiring CSI on channels relating to D2D pair and a plurality of cellular users that potentially share resources with the D2D pair; and determining D2D transmit powers of the D2D pair on a plurality of frequency bands allocated to the plurality of cellular users and cellular transmit powers of the plurality of cellular users based on the CSI, to improve throughput of the multicell network.

Dependent claims

A method for resource sharing for device-to-device (D2D) and cellular communications in a multicell network, comprising:

acquiring channel state information (CSI) on channels relating to D2D pair and a plurality of cellular users that potentially share resources with the D2D pair;
and
determining D2D transmit powers of the D2D pair on a plurality of frequency bands allocated to the plurality of cellular users and cellular transmit powers of the plurality of cellular users based on the CSI, to improve throughput of the multicell network.

An apparatus for resource sharing for device-to-device (D2D) and cellular communications in a multicell network, comprising:

an acquirer configured to acquire channel state information (CSI) on channels relating to D2D pair and a plurality of cellular users that potentially share resources with the D2D pair;
and
a determiner configured to determine D2D transmit powers of the D2D pair on a plurality of frequency bands allocated to the plurality of cellular users and cellular transmit powers of the plurality of cellular users based on the CSI, to improve throughput of the multicell network.

Dependencies are inferred from the claim text.
