Patent ID: 7277406

Claim:
A method of distributing 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) using a plurality of MCS (Modulation and Coding Scheme) levels determined in accordance with channel condition, each MCS level having an upper critical point and a lower critical point of the channel condition, the method comprising the steps of: channelizing a first high speed packet data and a second high speed packet data with corresponding channelization codes; lowering a first power for transmitting the first channel high speed packet data to UEs having channel conditions adjacent to the upper critical point in a specific MCS level by a surplus power; compensating for a second power for transmitting the second channel high speed packet data to UEs having channel conditions adjacent to the lower critical point in a specific MCS level by the surplus power; and combining the lowered first channel high speed packet data and the compensated second channel high speed packet data.
