Problems solved by technology

Since the paging indicator can be as short as one bit, changes in received signal quality conditions can corrupt the paging indicator bit and potentially cause the mobile wireless to miss paging messages, or read paging messages and thus unnecessarily waste power consumption in mobile wireless devices

Abstract

The application relates to an adaptive receive diversity during discontinuous reception in a mobile wireless device. The 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.

Description

[0001] priority [0002] This application claims priority to commonly owned and co-pending U.S. Patent Application Serial No. 13 / 231,804, filed September 13, 2011, and entitled "ADAPTIVE RECEIVE DIVERSITY DURING DISCONTINUOUS RECEPTION IN MOBILE WIRELESS DEVICE," which is hereby It is incorporated by reference in its entirety. technical field [0003] The described embodiments generally relate to methods and apparatus for employing receive diversity for mobile wireless devices. More specifically, the presented embodiments describe the selective use of receive diversity for mobile wireless devices having multiple receivers and multiple antennas during discontinuous reception mode. Background technique [0004] Mobile wireless devices in wireless networks can be designed to balance advanced communication capabilities with limited available power storage, especially in smaller form factor devices that offer "high performance" features such as those found in "smart" phones. Wh...
