SYSTEM AND METHOD FOR PERFORMANCE ENHANCEMENT IN HETEROGENEOUS WIRELESS ACCESS NETWORK EMPLOYING DISTRIBUTED ANTENNA SYSTEM

摘要

A system and method for dynamically optimizing the performance of indoor distributed antenna systems 8 communicating to user equipment 16 is disclosed. The user equipment evaluates information describing the downlink signals such as the downlink data rate, the quality of the received signal and the location of the user equipment. The service module 30 collects this information and determines the optimized power level of each of the antenna units 20. The service module 30 can optimize the power level of only one antenna unit or a subset of antenna units in the distributed antenna system 8 in one preferred embodiment. At this time, at least one of the antenna units 20 transmits downlink signals at optimized power levels. The optimized power level may be lower than the initial power level in a preferred embodiment. In another aspect, the system enhances the performance of multi-carrier base stations 300.
