Latest Patents

One of Lei Song's latest patents is titled "Method and apparatus for controlling reverse link interference rise and power control instability in a wireless system." This invention addresses the challenges of reverse link power control in wireless communications networks. It generates power adjust commands for mobile devices served by a network base station, focusing on overall system performance during increased interference conditions. The patent introduces a modified reverse inner loop power control (RILPC) and a reverse outer loop power control (ROLPC) algorithm to manage power adjustments effectively. By converting some power-up commands to power-down commands, the system can temporarily reduce transmit power to mitigate interference. The modified ROLPC algorithm further centralizes adjustments to target E/N levels, ensuring that only a limited number of increases occur during frame erasures.

Another significant patent by Lei Song is the "Method and system for controlling access of a subscriber station to a wireless system." This method enhances the performance of the reverse link and ensures desired geographic coverage. It involves measuring performance indicators for a subscriber station and establishing a blocking threshold value based on these metrics. The decision to grant or deny access is made by comparing the measured performance indicator to the established threshold, allowing for dynamic adjustments based on current conditions.
