Method and apparatus for controlling the increase of a reverse link interference and the instability in the power control in a wireless system

摘要

b method and control system of energy to generate commands for adjustment of transmission power in a wireless communication network d a system and a method for power control of link INSEESo in a wireless communication network to generate commands for power adjustment for mobile devices being served by a base station network in a centralized way considering the overall performance D.The system when a condition of increased interference is detected.In one implementation,A processor for power control of base station adopts an algorithm of power control of internal loop inverse modified (rilpc) and / or a power control loop of external inverse ROLPC) when a condition of increased interference is detected.According to the algorithm rilpc modified.A percentage of commands for adjustment of connection that would normally be generated when measurements of E ~ B ~ / N ~ ~ to mobile devices served not meet levels of E ~ B ~ / N ~ ~ target are converted.M controls adjustment of the turn off, thereby forcing some mobile devices to reduce power transmission, at least temporarily, to limit the interference.When the condition of interference increased persists, the percentage of commands for adjustment of connection are converted into commands to turn off can be changed.According to the algorithm rolpc modified.The processor of the power control adjusts levels of E ~ B ~ / N ~ ~ target in a centralized way based on a state of the overall system in such a way that allows only a limited number of levels.E ~ B ~ / N ~ ~ target increase when occurring restorations of the framework.Avoiding a percentage of increases in the level of E ~ B ~ / N ~ ~ target, at least temporarily, when restoration table occur, is not a percentage of controls adjustment of the call.Therefore, an effect similar to that obtained by the rilpc modified is obtained.According to an additional implementation of this invention.The algorithm of rilpc modified can be used in combination with the algorithm of rolpc modified to provide greater resistance to conditions of increased interference.
