摘要： During asymmetric communications using only the uplink, frame configuration section 109 transmits a signal made up of only pilot signals and transmission power control bits assembled into frames. The transmission power control method is the same as that for normal communications. In this case, since signals transmitted on the downlink are only pilot signals and transmission power control bits, it is possible to reduce the transmission rate considerably and transmit signals with its transmission power reduced by transmission signal amplitude control section 111. In this case, a long hierarchic orthogonal type spreading code is set as the spreading code used by spreader 110.

摘要： A mobile communication system is provided for increasing the capacity for personal stations and ensuring a radio channel for use with a micro cellular system irrespective of environment in which the system is installed. In the mobile communication system which allows the coexistence of a cellular automobile telephone system and a micro cellular system, communications in the cellular automobile telephone systems and the micro cellular systems are performed in a digital form, and a personal station accessing to each of these systems is connected thereto by using a time-division multiplex access mode or a code division multiplex access mode. Since the time-division multiplex access mode or code division multiplex access mode is used, a radio channel at the same frequency can be used by a plurality of personal stations. Thus, the capacity of the system can be increased for personal stations without extending a used frequency band.

摘要： Symbol 102 that is spread with the only short spreading code and inserted in synchronism with a long spreading code is specified by detecting the correlation with only the short spreading code. Next, another short spreading code indicative of a timing of reverse and forward link switching is specified, where the short spreading code is multiplexed at the same position as that of the detected symbol. The detection of the symbols spread with only these spreading codes enables to acquire synchronization of the long spreading code, synchronization of switching of reverse and forward links, and synchronization of a transmission frame. It is thereby possible to reduce synchronization acquisition time for the long spreading and an easy planning of base station locations without decreasing the frequency utilization efficiency.

摘要： In a base station which has a plurality of antennas, each of a plurality of comparison circuits operates to compare correlation levels, which are obtained by despreading received signals for a plurality of channels, with each other with respect to the antennas. Each of a plurality of transmission antenna selecting circuits operates to determine from which antenna a transmission signal is to be transmitted for every channel. Each of a plurality of multiplexing circuits operates to multiplex the transmission signals of the individual channels, which are spread, for every antenna. As a result, on the basis of the result of the comparison of the correlation levels with respect to the antennas, a transmission antenna is selected for every channel, and the signals of the channels that are to be transmitted by a given antenna are multiplexed, whereby the base station achieves transmission diversity.
