Diversity Control in a Wireless Communications Device

摘要

A method and apparatus controls diversity reception in a wireless communication device. By determining a value based on a number of active set pilot signals received from a set of base stations, the wireless communication device dynamically enables or disables diversity reception. Diversity reception can be controlled by adjusting a diversity threshold based on the determined value. A channel quality indicator of a channel is measured and compared against the adjusted diversity threshold. The diversity reception mode is then enabled or disabled based on the comparison. For example, if the number of active pilot signals is above a predetermined value, indicating“good”coverage, the diversity threshold is decreased. The measured channel quality indicator is compared against the adjusted threshold, and diversity reception is enabled when the channel quality indicator is less than the decreased diversity threshold.
