Patent ID: 7266384

Claim:
A DSCH power control method in a mobile communication system comprising: (a) receiving a signal from an UE: (b) determining whether a cell transmitting DSCH to be a set as primary or non-primary based on the received signal; and (c) adjusting DSCH transmit power according to a result of the determination, wherein (b) includes, (1) determining whether or not a primary cell ID code contained in the received signal matches a cell ID code of the cell, and setting the cell as primary if the cell ID code matches the primary cell ID code, (2) if the cell ID code matches the primary cell ID code, determining whether the received signal is encoded in normal mode or compressed mode, and if the received signal is encoded in the compressed mode, determining whether or not the number of bits punctured from the total number of bits N ID in the primary cell ID code is less than N ID /3, and setting the cell as primary when the number of punctured bits is not greater than N ID /3, and in all other situations, setting the cell as non-primary.
