Abstract: A propagation delay-propagation loss table is stored in advance in a radio base station, a first area and a second area being set in advance in the propagation delay-propagation loss table, the first area being predicted to contain the relation between the propagation delay and propagation loss when a mobile station is not within the service area of a repeater, while in the second area the effect of the control delay and power gain caused by the repeater upon this first area is taken into consideration. In the radio base station, it is then determined that a mobile station is within the service area of the radio base station when the relation between the propagation loss value that has been reported from the mobile station and the propagation delay that has been calculated is contained within the first area, and it is determined that the mobile station is within the service area of the repeater when the relation is contained within the second area.

Abstract: An object of the present invention is to provide a system for determining whether or not a mobile unit is present in the service area of a repeater through a simple system.

Abstract: A CDMA mobile communication system is disclosed in which a reference value, an uplink signal SIR value, which is used in a closed-loop transmission power control is updated in base transceiver stations. The uplink signal target SIR value is updated independently at base transceiver stations and not at the base station controller. At the base transceiver station, when a decoder detects a loss of synchronization of a user signal from a mobile station, a demodulator adds a step value ASIR that has been set in advance to the uplink signal target SIR value that has been reported from the base station controller to obtain an uplink signal target SIR provisional value. When this uplink signal target SIR provisional value is smaller than an uplink signal target SIR maximum value that has been set in advance, the uplink signal target SIR value is updated to the uplink signal target SIR provisional value.

The uplink signal target SIR value is updated independently at base transceiver stations and not at the base station controller.

When this uplink signal target SIR provisional value is smaller than an uplink signal target SIR maximum value that has been set in advance, the uplink signal target SIR value is updated to the uplink signal target SIR provisional value.

Abstract: Here is provided a mobile communication system which uses a plurality of channels for communication. The plurality of channels comprise a first channel on which a mobile terminal communicates simultaneously with both a first base station and a second base station in a handover state wherein the mobile terminal is in an overlapping area of a cell of the first base station and a cell of the second base station, and a second channel on which the mobile terminal communicates with one of the first and second base stations even in the handover state. The one of the first and second base stations comprises a handover state detector 22 for detecting information notified by a radio network controller regarding whether or not the mobile terminal is in the handover state, and also comprises a transmission power calculator 20 for calculating a value of downlink transmission power on the second channel on the basis of the information detected by the handover state detector 22.

Abstract: A CDMA mobile communication system is disclosed in which a reference value that is used in a closed-loop transmission power control is updated in base transceiver stations. The updating of an uplink signal target SIR value that serves as the reference in closed-loop transmission power control is performed independently at base transceiver stations and is not performed at the base station controller. At the base transceiver station, when a decoder detects a loss of synchronization of a user signal from a mobile station, a demodulator adds a step value ASIR that has been set in advance to the uplink signal target SIR value that has been reported from the base station controller to obtain an uplink signal target SIR provisional value, and when this uplink signal target SIR provisional value is smaller than an uplink signal target SIR maximum value that has been set in advance, the uplink signal target SIR value is updated to the uplink signal target SIR provisional value.
