Embodiment Construction

[0036] Various aspects of the present disclosure provide techniques for mitigating coexistence issues in multi-radio devices, where severe in-device coexistence issues can exist, for example, between LTE and Industrial, Scientific, and Medical (ISM) frequency bands (e.g., , for BT / WLAN). In one aspect of the present disclosure, mitigation of potential interference is achieved by aligning the timing of communications by the Bluetooth radio of a multi-radio UE with the timing of communications by the LTE radio. Alignment may include frame alignment, but may also include timing communications of the first radio access technology (RAT) according to various traffic scheduling rules to reduce interference between the first RAT and other RATs.

[0037] The techniques described herein can be used in various wireless communication networks, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) net...

Abstract

To mitigate potential interference between radio access technology (RAT) in a multi-RAT device, traffic scheduling rules may be implemented, such a manner to reduce interference to the communication timing of each RAT.For example, the communication may be scheduled Bluetooth / RAT of the WLAN, so that the Bluetooth / initial response and the WLAN communication during the sub-frame of the LTE RAT RAT occurs, which is unlikely to cause cross-interference RAT.

Description

[0001] Cross References to Related Applications [0002] This application for patent claims the benefit of U.S. Provisional Application No. 61 / 502,099, filed June 28, 2011, in the name of Linsky et al., which is assigned to the assignee of this application and is hereby incorporated by reference The entire disclosure of the provisional application is expressly incorporated herein. technical field [0003] In general, this specification relates to multi-radio technology, and in particular, this specification relates to coexistence techniques for multi-radio devices. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of such multiple access systems include Code Division Multiple Acces...
