Abstract
A scheme to reduce the problem of radio interference between wireless devices such as MTC devices in a multi-RAT scenario. Wireless devices are configured (S10) for interference reporting in accordance with their capabilities. Information is collected, not only on interference measurements reported by the wireless devices, but also on device signatures (S12) and transmission patterns (S14) for the purpose of attributing interference, suffered by a reporting device, to one or more offending devices (S16). One or more mitigation techniques is then applied to the offending device and/or the reporting device (S20-S24). The scheme provides an additional stability mechanism for existing interference mitigation and co-existence schemes by using device management and avoiding potential conflicts across diverse systems. Under the assumption that geographically co-located devices are all using a common service platform, the centralized algorithm permits more efficient solutions than existing interference mitigation solutions.
