Power Control Method of Forward Packet Channel in Code Division Multiple Access Mobile Communication System

摘要

The present invention relates to a power control method of a forward packet channel when a mobile terminal station is fixed in a packet transmission scheme of a code division multiple access mobile communication system and all the serviced terminal stations need to receive packet data of a base station.;When the base station transmits the packet data through the forward packet channel, the base station should transmit the packet data with outgoing power so that all terminal stations in the packet transmission service in the base station service area can receive the packet data. Assuming that the terminal station located at the boundary of the base station's service area should receive the packet data, the transmission power of the packet data is determined. When all the terminal stations serving the packet transmission service are located close to the base station, they are much larger than the required transmission power. It is transmitted by the transmission power, there is a problem that the effect of interference on the other channel is large.;In order to solve this problem, the base station manages a terminal station requesting a packet transmission service and determines the packet data transmission power at the instant of determining the packet data transmission power, and the terminal station determines the packet data transmitted by the base station. This paper proposes a power control method for the forward packet channel that minimizes the influence of interference on the forward channel by monitoring the error when the reception error occurs and reports it to the base station to reflect it in determining the packet data transmission power. do.
