Problems solved by technology

[0011] Other unilateral actions on the part of the UE, such as simply stopping uplink communication without coordinating the eNB, may lead to power loop failure at the eNB
Other issues that exist in legacy LTE include the usual lack of ability on the part of the UE to suggest desired configurations as alternatives to configurations with coexistence issues
For at least these reasons, the uplink coexistence problem at the UE may remain unresolved for a long time, reducing the performance and efficiency of the UE's other radios

Embodiment Construction

[0031] Aspects of the present application provide techniques for mitigating coexistence issues in multi-radio devices, where significant in-device coexistence issues may exist, for example, between LTE and Industrial Scientific and Medical (ISM) bands (e.g., for BT / WLAN )between. In certain scenarios, bursts of interference may cause coexistence issues with one or more radio access technologies (RATs). When such a burst of interference is detected, a coexistence indication may be sent to a coexistence manager or base station to manage the coexistence issue. To detect bursty interference, the UE may analyze the measured signal to identify multi-mode distributions, which may trigger a coexistence indication.

[0032]The techniques described herein can be used in a variety of wireless communication networks, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OF...

Abstract

A user equipment (UE) may reduce coexistence issues with one or more radio access technologies (RATs) caused by a bursty interference. The bursty interference may be detected by detecting a number of modes in a measured signal sample and determining when a signal contains a multi-modal distribution based at least in part on the detecting. A coexistence indication is created based at least in part on the determining.
