Interference avoidance in D2D communications
First Claim
1. A computer-implemented method for allocating radio resources for a device-to-device (D2D) communication between a first D2D device and a second D2D device:
- identifying one or more devices relevant for the D2D communication between the first D2D device and the second D2D device;
for each device of the identified devices, obtaining location information for the device;
for each device of the identified devices, using the location information obtained for the device and one or both of location information for the first D2D device and location information for the second D2D device, determining a distance parameter indicative of a distance between one of the device, a device pair comprising the device and a further entity or a further device with which the device is in communication, or a group of further devices comprising the device and a plurality of further entities or further devices with which the relevant device is in communication, and one of the first D2D device, the second D2D device, or a device pair comprising the first D2D device and the second D2D device;
allocating one or more radio resources for the D2D communication between the first D2D device and the second D2D device based on the determined distance parameter;
assessing a D2D transmit power to be used by at least one of the first D2D device or the second D2D device for the D2D communication between the first D2D device and the second D2D device; and
for each device of the identified devices;
determining a victim interference parameter using the determined distance parameter and the assessed D2D transmit power, the victim interference parameter being indicative of an interference level at the device attributable to the D2D communication between the first D2D device and the second D2D device, anddetermining whether the victim interference parameter satisfies a victim condition,wherein the allocating comprises allocating one or more radio resources for the D2D communication between the first D2D device and the second D2D device based on radio resources allocated to the one or more devices for which the victim interference parameter was determined to satisfy the victim condition.

Abstract
A method for allocating radio resources for a D2D communication between a first device and a second device is disclosed. The method includes identifying device(s) relevant for the D2D communication between the first and second devices, obtaining location information for the identified device(s), determining a value of a distance parameter for each of the identified devices using the location information obtained for the device and one or both of location information for the first device and location information for the second device, and allocating one or more radio resources for the D2D communication between the first device and the second device based on the determined value of the distance parameter.

10. A computer program product, stored on a computer-readable non-transitory storage medium, comprising software code portions, which when executed in a computer, cause the computer to:
-
identify one or more devices relevant for a device-to-device (D2D) communication between a first D2D device and a second D2D device; for each device of the identified devices, obtain location information for the device; for each device of the identified devices, using the location information obtained for the device and one or both of location information for the first D2D device and location information for the second D2D device, determine a distance parameter indicative of a distance between one of the device, a device pair comprising the device and a further entity or a further device with which the device is in communication, or a group of further devices comprising the device and a plurality of further entities or further devices with which the relevant device is in communication, and one of the first D2D device, the second D2D device, or a device pair comprising the first D2D device and the second D2D device; allocate one or more radio resources for the D2D communication between the first D2D device and the second D2D device based on the determined distance parameter; assess a D2D transmit power to be used by at least one of the first D2D device or the second D2D device for the D2D communication between the first D2D device and the second D2D device; and for each device of the identified devices; determine a victim interference parameter using the determined distance parameter and the assessed D2D transmit power, the victim interference parameter being indicative of an interference level at the device attributable to the D2D communication between the first D2D device and the second D2D device, and determine whether the victim interference parameter satisfies a victim condition, wherein, to allocate the one or more radio resources, the software code portions when executed in the computer further cause the computer to allocate the one or more radio resources for the D2D communication between the first D2D device and the second D2D device based on radio resources allocated to the one or more devices for which the victim interference parameter was determined to satisfy the victim condition.
