20080207245 | Mobile Communications System, Base Station Control Apparatus, and Mobile Terminal - A mobile communications system in which plural possible values for a maximum number of non-serving base stations which can be selected by a base station control apparatus are made available, and the maximum number is set up among the plural possible values for the maximum number of non-serving base station made available according to the capability of mobile terminal. Thereby, in a case in which the mobile terminal has a low transmission rate, an advantage of being able to reduce the circuit size of the receiving circuit of the mobile terminal is realized. | 08-28-2008 |
20080253300 | Communication Quality Judgment Method, Mobile Station, Base Station, and Communications System - In order to carry out high-speed packet communications using a large-volume transmission channel like an E-DCH, uplink communication quality must be good. However, in a state in which a link imbalance occurs, a mobile station cannot estimate the uplink communication quality from downlink communication quality. Therefore, the mobile station calculates a path loss from the setting power of a common pilot channel which is notified from a base station, and the received power of the common pilot channel received thereby, and also estimates the received power in the base station on the basis of this path loss. The mobile station further judges the uplink communication quality by estimating the SIR in the base station by using the interference power notified from the base station and the estimated received power. | 10-16-2008 |
20080254819 | Mobile Station, Fixed Station, Communication System and Communication Method - For lack of a unique, specific and detailed specification for information on the status of a mobile station to be notified by the mobile station to a fixed station, the operation may be varied from one mobile station to another in a communication system, thereby posing a problem that an efficient uplink scheduling (radio resource assignment) is impossible. | 10-16-2008 |
20080305790 | Mobile Communication Terminal and Radio Communication System - A mobile communications terminal divides a plurality of multipath signals associated with radio signals transmitted from a plurality of base stations | 12-11-2008 |
20080318586 | COMMUNICATIONS SYSTEM, COMMUNICATIONS APPARATUS, COMMUNICATIONS TERMINAL AND COMMUNICATIONS METHOD - According to a communications method according to the present invention, data is transmitted from a base station to two or more terminals via a common channel, and transmission power, with which the data is transmitted from the base station to the two or more terminals, is controlled according to a reception state of at least one of the two or more terminals. Furthermore, the terminal transmits reception capability information at a time of selection combining, and at least one of the two or more base stations receives the reception capability information at the time of selective combining and notifies the reception capability information to a radio network controller (RNC) which controls the two or more base stations. When a connection request is issued to the terminal, the RNC refuses assignment of a dedicated channel to the connection request when determining that the assignment of the dedicated channel to the terminal cannot be done based on the reception capability information at the time of selective combining. | 12-25-2008 |
20090016278 | Base station, mobile communication terminal equipment, and primary cell determination method - A base station receives a signal transmitted from a mobile station, estimates the state of the radio uplink, and receives state information indicating the state of the radio downlink measured by the mobile station. When the uplink quality and the downlink quality satisfy scheduling grant conditions set up in advance, the base station is allowed to carry out scheduling for the mobile station. In contrast, the base station is not allowed to carry out the scheduling for any terminal in which a link imbalance has occurred. Therefore, the throughput of the whole system increases. | 01-15-2009 |
