METHOD AND DEVICE FOR DOWN-LINK COMMUNICATION LINES OF REDUCED AVERAGE TRANSMITTED POWER FROM CENTRAL NODES IN COURSE OF SOFT TRANSMISSION

摘要

FIELD: communications. SUBSTANCE: first method involves delay of "softer" transmission. Second method involves decreased power of transmission from sector with lowermost signal level. Third method involves interruption of transmission from sector with lowermost signal level. Fourth method involves use of additional central node or only sector if robust operations of mobile unit require additional power. All four methods involve continued demodulation of reply transmission line during transmission through direct transmission line or without communication through direct transmission line. Operation in all four methods is based on signal level on direct or reply transmission lines. In addition two or several methods may be joined to achieved mixed method. EFFECT: increased signal-to-noise ratio, decreased power transmitted from central node, improved soft transmission method to improve operations of down-link transmission line. 22 cl, 3 dwgd
