Dynamic resource selection to reduce interference that results from direct device to device communications
First Claim
1. A network node configured to select resources for a direct device to device communication link between a first wireless device and a second wireless device in a cellular communication network, comprising:
- a transceiver sub-system configured to enable wireless communication; and
a processing sub-system associated with the transceiver sub-system configured to;
select a downlink resource of the cellular communication network as a resource for the direct device to device communication link between the first wireless device and the second wireless device if a base station serving the first wireless device and a base station serving the second wireless device are equipped with an interference cancellation receiver and both a radio distance between the first wireless device and the base station serving the first wireless device and a radio distance between the second wireless device and the base station serving the second wireless device are less than a predefined threshold radio distance; and
select an uplink resource of the cellular communication network as the resource for the direct device to device communication link between the first wireless device and the second wireless device if the base station serving the first wireless device and the base station serving the second wireless device are equipped with an interference cancellation receiver and at least one of the radio distance between the first wireless device and the base station serving the first wireless device and the radio distance between the second wireless device and the base station serving the second wireless device is greater than the predefined threshold radio distance.

Abstract
Systems and methods are disclosed for selecting resources for direct device to device (D2D) communications in a cellular communication network. In one embodiment, a downlink resource is selected as a resource for a direct D2D communication link between a first wireless device and a second wireless device if a base station serving each of the first and second wireless devices is equipped with an interference cancellation receiver and both the first and second wireless devices are less than a predefined threshold radio distance from their serving base station. An uplink resource is selected as a resource for the direct D2D communication link if the base station serving each of the first and second wireless devices is equipped with an interference cancellation receiver and at least one of the first and second wireless devices is more than the predefined threshold radio distance from its serving base station.
