SPREAD-SPECTRUM COMMUNICATION SYSTEM INCLUDING BASE STATION AND SUBSCRIBER STATION

摘要

PROBLEM TO BE SOLVED: To form a plurality of user bearer channels with predetermined radio frequency, to allow dynamic allocation of bearer channel speed while preventing multipath interference and to suppress the total amount of system transmission power.

SOLUTION: This spread-spectrum communication system is configured that a base station comprises a means for transmitting a global pilot code signal, a forward direction automatic power control bit and a forward direction traffic channel to a subscriber station unit and a means for controlling transmission power levels of a forward direction traffic channel and the forward direction automatic power control bit in response to a backward direction automatic power control bit and the subscriber station unit comprises: a means for transmitting an allocated pilot code and the backward direction automatic power control bit to the base station; a means for transmitting a backward direction traffic channel to the base station and a means for controlling the transmission power level of the pilot code allocated in response to the forward direction automatic power control bit, the backward direction automatic power control bit and the backward direction traffic channel.
