Abstract

Methods and apparatus for detecting and mitigating interface conditions at a multi-radio device. In one embodiment, a multi-radio device monitors and detects an in-device coexistence (IDC) interference condition which is, for example, caused by concurrent operation of radios. In response, the device notifies a network entity (e.g., a Long Term Evolution (LTE) eNodeB) of the detected IDC condition. Upon receiving the notification of the IDC condition, the network entity may implement or invoke a mitigation scheme in order to reduce the amount of IDC experienced at the client device.

First claim

What is claimed is:

1. A method for mitigating multi-radio interference at a wireless device operating within a cellular network, the method comprising:
by the wireless device:
obtaining, from a second wireless device proximate to the wireless device via a wireless connection between the wireless device and the second wireless device, information about an interference condition between at least two radio interfaces of the wireless device to occur at a scheduled time;
in respon…
