Embodiment Construction

[0028] Reference will be made in detail to various embodiments of the present invention, and the accompanying drawings are made to illustrate the embodiments of the present invention.

[0029] image 3 A user equipment UE 31 having multiple transceivers in a wireless communication system 30 is described in accordance with novel aspects. The wireless communication system 30 includes a user equipment UE 31, a serving base station (for example, an evolved node B (evolved Node-B) eNB 32, a wireless fidelity (WiFi) access point (Access Point) WiFi AP 33, a Bluetooth device BT 34 and Global Positioning System satellite device GPS 35. Wireless communication system 30 provides UE 31 with various network access services via different radio access technologies. For example, eNB 32 provides Orthogonal Frequency Division Multiple Access (OFDMA-based) cellular radio Network (for example, 3rd Generation Partnership Project (3GPP) LTE or LTE-A system) access, WiFi AP 33 provides regional ra...

Abstract

A method to trigger in-device coexistence (IDC) interference mitigation is provided. A wireless device comprises a first radio module and a co-located second radio module. The first radio module measures a received radio signal based on a plurality of sampling instances. A control entity obtains Tx / Rx activity of the second radio module and informs Tx / Rx timing information to the first radio module. The first radio module determines a measurement result based on the obtained timing information. The first radio module triggers an IDC interference mitigation mechanism if the measurement result satisfies a configurable condition. In one embodiment, the first radio module reports IDC interference information and traffic pattern information of the second radio module to a base station for network-assisted coexistence interference mitigation. The IDC triggering mechanism prevents unnecessary and arbitrary IDC request from the device and thus improves network efficiency.
