Apparatus and method for controlling power of reverse channels in a mobile communication system |
摘要 |
Disclosed is an apparatus for performing power control on a reverse channel quality indicator channel (CQICH) received from a mobile station by a base station in a mobile communication system including the base station for transmitting a power control bit for power control on reverse channels and the mobile station for controlling transmission power of the reverse channels according to the power control bit. An erasure detector determines whether to perform an erasure process by measuring reception power of the reverse channel quality indicator channel. An erasure rate calculator accumulates the erasure-determined result for N slots and calculates an erasure rate for the N slots. A control bit generator determines a ratio control bit to be transmitted to the mobile station according to the erasure rate, to issue a command to increase or decrease a CQICH traffic-to-pilot ratio.
