Improved Transmission Power Control for Disruptions in Cellular Communications - CDMA SEP portfolio    

Multinational patent portfolio covering standards essential techniques used in CDMA wireless communications for transmission power control with improvements to handle disruptions in transmissions.


The technology is concerned with power control techniques used in such systems to improve performances, in terms of quality of service, capacity, etc., despite continuous changes in their respective locations with respect to fixed infrastructures in such systems. The technology is in particular applicable to mobile radio communication systems of CDMA ("Code Division Multiple Access") type. CDMA is a multiple access technique which makes it possible for several users to be simultaneously active on a same frequency, using different spreading codes.
