    • A mobile communication system includes a plurality of base stations in a communication service area connected to a packet communications network. A mobile station communicates with a second station through the plurality of base stations and the network. The mobile communication system determines a virtual base station group as an aggregation of the plurality of base stations communicating with the mobile station, based on a condition of a radio transmission path between the mobile station and each base station, and combines information received by the plurality of base stations that belong to the virtual base station group at a base station included in the virtual base station group. The network connects the plurality of base stations non-hierarchically and the base station transmits combined information to the second station through the network relative to combined packets having the second station as a destination.

    • A mobile communication scheme realizing highly reliable handover and improved service quality. The communication signals containing identical communication data are transmitted simultaneously from the mobile station to more than one base stations at a time of the handover, such that reception signals are composed from the communication signals received by more than one base stations by using the reliability information for the received communication signals. For the packet communication, the identification information for identifying each packet is attached to each packet, and the reliability information for each packet is measured, such that the reception packets can be obtained according to the identification information attached to each packet and the reliability information measured for each packet.

    • A transmission power control scheme for a mobile communication system for suppressing the transmission power to an absolutely necessary minimum level, and increasing the subscriber capacity by reducing an amount of interference. In this scheme, at a time of controlling a transmission power of each radio channel at one of the base station and the mobile station so as to make a difference between a target CIR and a reception CIR of each radio channel at another one of the base station and the mobile station smaller, the target CIR for all radio channels at that another one of the base station and the mobile station are set independently, and/or the target CIR for each radio channel is changed at that another one of the base station and the mobile station, according to a channel quality of each radio channel at either one of the base station and the mobile station.

    • A transmission power control method for a CDMA system including the steps of calculating an actual SIR (Signal-to-Interference Ratio) of a desired signal; deciding whether the actual SIR is greater than a predetermined reference SIR which satisfies a predetermined conununication quality; forming a transmission power control bit on the basis of a result of deciding; inserting the transmission power control bit periodically into a forward frame, which steps are performed at the base station, and steps of calculating tentative reverse transmission power in accordance with the transmission power control bit in the forward frame; deciding reverse transmission power such that the reverse transmission power is made equal to the tentative reverse transmission power when the tentative reverse transmission power is less than a predetermined maximum transmission power, but otherwise made equal to the predetermined maximum transmission power; and transmitting a signal from the mobile station to the base station at the reverse transmission power, which steps are performed at the mobile station.
