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.).

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： It is possible to use a frequency of a preferable propagation condition while reducing the other cell interference by hopping. A scheduler section (102) performs scheduling for deciding a user to whom data is transmitted, by using the CQI from each communication terminal device, selects a user signal to be transmitted in the next frame, and decides a sub-carrier block by which the transmission is performed. An MCS judgment section (103) selects a modulation method and a coding method from the CQI of the user signal selected. A sub-carrier block selection section (110) selects a sub-carrier block specified by the scheduler section (102) for each user signal. For each of the sub-carrier blocks, the hopping pattern is selected by FH-sequence selection sections (111-1 to 111-n). A sub-carrier mapping section (112) maps the user signal and the control data to the sub-carrier according to the hopping pattern selected.

摘要： Provided is a base station capable of giving a pilot appropriate for both of multicast data and unicast data which are frequency-multiplexed. In a pilot generation unit (105) of the base station, an insertion unit (1051) inserts a pilot (common pilot) common to a plurality of cells to generate an orthogonal pilot sequence (2). In accordance with the insertion process in the insertion unit (1051), an insertion unit (1052) inserts a sequence (common sequence) common to a plurality of cells to a unique scrambling sequence to generate a scrambling sequence. A scrambling unit (1053) performs a scrambling process for multiplying the orthogonal pilot sequence (2) by the scrambling sequence. This scrambling process generates, in a part of pilot sequences different for respective cells, a pilot sequence containing a pilot common to the cells.

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.
