Dynamic spectrum band selection for D2D communications
First Claim
1. A method of operation of a control node in a cellular communication network comprising:
- selecting a resource for a direct device-to-device communication link between a first wireless device and a second wireless device in the cellular communication network based on a plurality of criteria comprising a service area type for a service area within the cellular communication network in which the first wireless device and the second wireless device are located, wherein the service area type for the service area is one of a group consisting of;
a homogeneous service area in which all base stations in the service area are macro base stations, and a heterogeneous service area in which one or more base stations in the service area are low-power base stations; and
communicating an indicator of the resource selected for the direct device-to-device communication link to at least one of the first wireless device and the second wireless device.

Abstract
The present disclosure provides systems and methods for selecting a resource for a direct device-to-device (D2D) communication link between wireless devices in a cellular communication network. In one embodiment, a control node in a cellular communication network selects a resource for a direct D2D communication link between a first wireless device and a second wireless device based on one or more criteria including a service area type of a service area within the cellular communication network in which the first wireless device and the second wireless device are located. The service area type is either homogeneous or heterogeneous. The control node communicates an indicator of the resource selected for the direct D2D communication link to the first wireless device and/or the second wireless device. Thereafter, the first and second wireless devices communicate over the direct D2D communication link using the selected resource.
