Abstract
The present invention is a method and apparatus for reducing co-channel interference. The present invention includes a powerful means for eliminating co-channel interference from base stations in a wireless communication system. The present co-channel interference reducing method and apparatus utilizes frame synchronization between selected time frames (e.g., odd and even time frames) to reduce co-channel interference. Advantageously, the present invention reduces co-channel interference and, thus, allows robust modulation schemes to operate even at worst case line-of-sight (LoS) interference scenarios of 100%. The present invention can also use an uplink/downlink ratio formula to further improve system capacity (i.e., reduce co-channel interference) in ATDD systems. The present inventive method and apparatus can be used in any type of frame based and frame synchronized communication system.
