AI Technical Summary

Problems solved by technology

Data received by the victim technology can be corrupted by desensitized interference sent from the aggressor
In this regard, incorrectly received data packets or even a complete lack of reception by the victim technology receiver may be due to interference that may be caused by the transmission of the aggressor technology
For example, a device sending a cellular signal while receiving a Bluetooth or wireless local area network (WLAN) signal may completely miss the signal from the Bluetooth or WLAN receiver, causing errors and, in some cases, a complete loss of the connection

Embodiment Construction

[0016] Some example embodiments described herein address in-device coexistence between wireless communication technologies. More specifically, some example embodiments described further herein address issues in which a transmission is transmitted by a device via an aggressor technology when the device is about to receive data over a victim technology. In such cases, the aggressor technology transmission may inhibit the reception of data via the victim technology, which may cause received data to be erroneous, or in extreme cases, even cause the victim technology receiver to lose the signal at all. For example, cellular transmissions may prevent data reception via ISM band technologies when devices are simultaneously communicating via cellular communications and low-power communications technologies employing the Industrial, Scientific, and Medical (ISM) band, such as Electrical and Electronics Institute of Engineers (IEEE) 802.15 wireless personal area network (PAN) communicat...

Abstract

The invention relates to facilitating in-device coexistence between wireless communication technologies, and particularly relates to a method for facilitating in-device coexistence between wireless communication technologies on a wireless communication device. The method can include transmitting data traffic from the wireless communication device via an aggressor wireless communication technology;determining occurrence of an in-device interference condition resulting from transmission of the data traffic via the aggressor wireless communication technology interfering with concurrent data reception by the wireless communication device via a victim wireless communication technology; and reducing a bit rate of the data traffic transmitted via the aggressor wireless communication technology in response to the in-device interference condition.

Description

[0001] This application is a divisional application of Chinese patent application 201380073674.8 with a filing date of December 9, 2013 and an invention title of "Promoting In-Device Coexistence Between Wireless Communication Technologies". technical field [0002] Embodiments described herein relate generally to wireless communications and, more particularly, to facilitating in-device coexistence between wireless communications technologies. Background technique [0003] Many wireless communication devices support and may communicate concurrently via multiple wireless communication technologies. In many cases, wireless communication technologies used by devices may use channel frequency bands that may interfere with each other. In such cases, energy from the frequency band used by one technology may leak into the frequency band used by another technology. This energy leakage can raise the noise floor and cause a problem known as desensitization. In many cases, desensitiza...
