摘要： Disclosed is a method and an apparatus for controlling transmission electric power capable of minimizing a decrease in the amount of maximum transmission electric power without degrading an adjacent channel leakage power ratio when code-multiplexing additional control information with data and main control information. A mobile device checks values of gain factors βd and βc when performing code multiplexing to transmit signals from channels DPDCH to transmit data, DPCCH to transmit main control information, and HS-DPCCH to transmit additional control information. A maximum transmission electric power is decreased at a plurality of levels based on the check result and a ratio (Δhs) between the gain factors βc and βhs. It may be preferable to check the presence or absence of transmission data instead of the gain factor βd. In this case, when no transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on Δhs. When transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on the gain factor βc and Δhs.

摘要： The present invention relates to an information processing apparatus and a communication apparatus for accurately recognizing at the base station the current receiving quality of the mobile terminals for improving the throughput of the base station. A mobile terminal 61 determines its own receiving quality based on the signal received from the base station 62 for generating the receiving quality message indicating the receiving quality and generates the power control information requesting the transmission power of the base station 62. The receiving quality message is transmitted at a frame rate and power control information is transmitted at the slot rate to the base station 62. Based on both the receiving quality message and power control information, the base station 62 estimates the current receiving quality of the mobile terminal 61 and adaptive modulation and coding is performed based on the estimated value. The present invention may be applied to cellular phones and base stations.

摘要： Disclosed is a wireless communication system wherein frame data is encoded with an outer code and then divided into predetermined number of blocks which are encoded with an inner code into transmission data which a receiver receives by wireless In the receiver, a decoder decodes the received transmission data in accordance with the inner code, a retransmission order determining unit determines whether or not to perform a retransmission order in units of blocks based on the likelihood information (decoded soft-decision value). At this time, the retransmission order determining unit inhibits the retransmission order for the block if the number of inner-code errors in a frame consisting of predetermined number of blocks stays within a limit of what the outer code can correct at a decoder and determines that a retransmission is necessary if the number of inner-code errors in the frame exceeds the limit. An average value of absolute values of the likelihood information within a block, for example, can be used as an evaluation value.

摘要： In the mobile terminal, the reception quality estimating unit measures a reception quality, and at least one of the data buffer monitoring unit and the transmission power monitoring unit measures a data transmission capability. Based on the measured reception quality and data transmission capability, the terminal determines a transmission mode to be used, and reports it to the base station. The base station determines the transmission mode to be practically used in accordance with the reported transmission mode, and notifies it to the mobile terminal. The base station transmits data according to the determined transmission mode, and the mobile terminal receives data according to the notified transmission mode. Thereby, the radio communication system determines the transmission mode in consideration for not only the reception quality, but also the deficiency in the data transmission capability of the terminal.

摘要： In a cellular mobile telecommunications system, upon a hand-off request signal generated by a mobile station, the base station control office transfers traffic data to both the base station to which the mobile station is presently connected and another base station to which the present base station is adjacent. A hand-off order message is transferred from the present base station toward the mobile station. The control office is adapted to control the adjacent base station to transmit the hand-off order message if it fails to receive a hand-off confirmation from the mobile station.
