    摘要: A server (191) transmits image information consisting of basic data and complementary data to a router (100) through the Internet (192). The router (100) allocates the basic data to a BS (110) of a cellular system (193) and the complementary data to an AP (120) of a wireless LAN system (194). The BS (110) transmits the basic data to a MS (150) and the AP (120) transmits the complementary data to the MS (150). When the MS (150) is located in the area of the cellular system (193), the MS always maintains a communication channel with the BS (110) and when the MS enters the area of the wireless LAN system (194), the MS also opens a channel with the AP (120) while maintaining the channel with the BS (110). This allows the user to continue seamless communication.

    摘要: A mobile communication system which is capable of, when carrying out mobile communication using a shared channel, increasing in efficiency of transmission timing of the data transmission rate request value to prevent wasteful power consumption and hence reduce power consumption. A mobile station apparatus of the mobile communication system measures CIR of the received signal from a base station apparatus at a CIR measuring section, and decides the data transmission rate request value corresponding to the measured CIR value at a rate request value deciding section. Also, it detects an error of the received signal at a CRC section, and, when no error is found, calculates a difference between the average data transmission rate from a base station apparatus and the data transmission request value at a rate request value transmission controlling section. Then, it transmits the data transmission rate request value to the base station apparatus only when the obtained difference is larger than a threshold value.

    摘要: An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.

    摘要: Priority determining section 107 determines priority of each communication terminal apparatus based on the information indicating the channel quality of the downlink. Transmission destination determining section 108 estimates the direction in which each communication terminal apparatus exists from the information indicating the direction of arrival of the signal and determines the communication terminal apparatuses to which downlink high-speed packet transmission is performed based on the direction in which each communication terminal apparatus exists and priority. AAA transmission control section 154 calculates a transmission weight based on the direction of arrival of the signal sent from the communication terminal apparatus determined by transmission destination determining section 108. Then, AAA transmission control section 154 multiplies the signals sent from antenna elements 101 to 103 by transmission weights. When adaptive array is used, this makes it possible to carry out effective downlink high-speed packet transmission.
