Anordnung und Verfahren zur Leistungsverteilung in einem HSDPA System (Hochgeschwindigkeits-Abwärtsverbindung-Paket-Zugriff)

摘要

A method of distribution power in a CDMA (Code Division Multiple Access) mobile communication system in which a node B transmits high speed packet data to UEs (User Equipment) located in an area occupied by the node B, the area being divided into a plurality of channel condition areas, each of the channel condition areas having an upper critical value and a lower critical value, each of the channel condition areas containing a plurality of UEs which receive the high speed packet data with a same coding rate and in a same modulation scheme, the method comprising the steps of: lowering a first power for transmitting the high speed packet data to UEs having channel conditions adjacent to the upper critical value of each of the channel condition areas by a surplus power; and compensating for a second power for transmitting the high speed packet data to UEs having channel conditions adjacent to the lower critical value of each of the channel condition areas by the surplus power.
