Abstract: A method for facilitating in-device coexistence between wireless communication technologies on a wireless communication device is provided. 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.

Abstract: A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

Abstract translation: 移动无线设备基于下行链路信号质量，页面指示符和寻呼消息来适应不连续接收期间的接收分集。 当下行链路信号质量超过预定阈值时，移动无线设备通过初始天线解码页面指示符信道，否则，通过初始天线对寻呼信道进行解码，而不对页面指示符信道进行解码。 当页面指示符被解码为擦除时，移动无线设备切换到通过替代天线解码寻呼信道。 当通过单个天线接收的寻呼消息用错误的错误校验码进行解码时，移动无线设备能够通过多个天线进行接收分集以用于后续解码。 基于跟踪多个连续的错误检查代码故障和成功，移动无线设备在单天线接收和多天线接收之间切换。
