摘要： In order to perform appropriate reception quality control on each mobile station in a multimedia broadcast/multicast service, a layered coding section 101 encodes input data by dividing the input data into two layers and obtains a first layer code string and a second layer code string. The first layer code string is input to a CRC code addition section 102 and a CRC code for an error inspection is added thereto at every predetermined block. On the other hand, the second layer code string is input to a CRC code addition section 103 and a CRC code for an error inspection is added thereto at every predetermined block. The first layer code string and the second layer code string with the CRC codes added are input to a layered modulation section 104 and the layered modulation section 104 modulates a plurality of code strings coded by being divided into a plurality of layers in such away that error rates differ hierarchically among the plurality of code strings and a radio section 105 sends the modulated symbol.

摘要： A radio communication system and scheduling method where, when data are transmitted from a plurality of transmit antennas to respective different mobile station apparatuses, all the mobile station apparatuses precisely receive data addressed thereto. A scheduler (104) performs scheduling that determines a data transmit order, depending on the numbers of receive antennas of the respective mobile station apparatuses, and notifies a transmit antennas assignment signal generator (124) of which transmit antenna is assigned which mobile station apparatus's sub-stream as the scheduling result. A number of receive antennas notifying signal decoder (122) decodes the number of receive antennas notifying signals and notifies the number of the receive antennas of each mobile station apparatus to the scheduler (104). The transmit antennas assignment signal generator (124) generates the transmit antennas assignment signal indicating which transmit antenna is assigned which mobile station apparatus's sub-stream.

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： In order to appropriately control transmit power of a common channel for an MBMS (Multimedia Broadcast/Multicast Service) so as not to become excessive, a mobile station 1 transmits a TPC command for an S-CCPCH to a base station through an uplink DPCH1 and a mobile station 2 transmits a TPC command for an S-CCPCH to the base station through an uplink DPCH2. When either one of the TPC command for the S-CCPCH transmitted from the mobile station 1 and the TPC command for the S-CCPCH transmitted from the mobile station 2 is a TPC command instructing “Up”, the base station increases transmit power of the downlink S-CCPCH and decreases transmit power of the downlink S-CCPCH when both TPC commands instruct “Down”.

摘要： A reception power measurement section 107 measures reception power from received data. A transmission power information extracting section 106 extracts information of transmission power of a dedicated channel of mobile equipment included in received data. A condition setting section 108 calculates a transmission parameter of packet data and transmission power in scheduled mobile equipment using information of reception quality, reception power and transmission power of the dedicated channel, and outputs information of the calculated parameter and transmission power command information to channel coding sections 111-1 to 111-n. The channel coding sections 111-1 to 111-n code transmission data including transmission power command information and transmission parameter information to be notified to the scheduled mobile equipment. This makes it possible to perform communications based on suitable resource management in an uplink.

摘要： A base station apparatus and communication terminal apparatus capable of estimating interference with other cells on an uplink and realizing optimum assignment. At a base station (100), a scheduling and transmission parameter determining section (113) receives soft handover information from a higher layer and does not perform individual assignment processing for a mobile station in the process of soft handover. In this way, the mobile station can perform continuous transmission at a constant transmission rate (e.g., coding rate, modulation scheme, spreading factor, transmit power, etc.).
