Abstract
In a mobile communication system in which a TDMA system and a time-divided CDMA system are commonly used, a high-speed TDMA data transmission system is introduced, and down-links, from base stations (1 to 3) to mobile stations (31 to 34, 41, 42, 51 and 52) and up-links, from mobile stations to base stations, comprise different communication capacities from each other and a couple of a down-link and an up-link having different communication capacities are handled as one communication channel (asymmetric channel). A mobile communication system which is to transmit a large quantity of high-speed data and is able to correspond to multimedia circumstances may be realized by assigning the above-mentioned asymmetric channel to the mobile communication system.
