摘要： In a conventional cellular wireless communication system that included a plurality of base station apparatuses having a plurality of antennas, just two antennas were used for simultaneous transmission by transmission diversity, and the antenna usage efficiency was low. According to the present invention, a free transmission diversity antenna for transmission to the edge of a cell is used to send a signal to a terminal located around the center of the cell without causing interference to a terminal located around the edge of the cell. The two terminals located around the edge of the cell and around the center of the cell are paired for simultaneous signal transmission. A signal directed to the edge of the cell and a signal directed to the center of the cell are sent with greatly different transmission power. This reduces the interference caused by the signal directed to the center of the cell to an insignificant level for the terminal located around the edge of the cell. The terminal located around the edge of the cell does not appear to be affected by interference from signal transmission to the center of the cell and does not have to always use four antennas.

摘要： Ameliorate deterioration in quality of communication caused by intercell interference with respect to a multicarrier communications protocol, such as OFDM. A method of positioning an error correction-coded signal is changed with a data symbol that is transmitted simultaneously with a pilot signal and a data symbol that is not simultaneous with the pilot symbol. Else, a modulation protocol is changed with a data symbol that is transmitted simultaneously with a pilot signal and a data symbol that is not simultaneous with the pilot symbol. It would further be permissible to lower either a signal amplitude or a power level of a data symbol that is transmitted simultaneously with a pilot signal.

摘要： There are provided scheduling and a resend control system, which match simultaneous communications using a plurality of carriers. For individual carriers to be used, the simultaneous resend control of the carriers is made by notifying channel information and a data decoding result and by managing the resend numbers. Even in case the communications are performed by using the carriers simultaneously between a base station and a terminal, the scheduling can be done to contain the resend control. It is also possible to improve the communication quality and the throughput.

摘要： By using the delay profile created by delay profile creating section 102 and the first threshold value 330 received from the first threshold value calculation 105, the first threshold value timing detection section 103 selects only the earliest receive timing exceeding the first threshold value, from all the timing that the correlation value in the delay profile becomes a maximum.

摘要： The present invention pertains to the technology for avoiding interference between adjacent frequencies occurring on cell boundaries or sector boundaries in a mobile wireless communication system using an OFDMA (Orthogonal Frequency Division Multiple Access) scheme. There are a single sector mode of no collaboration between sectors; a sector selection mode of collaborating between sectors to transmit with a specified frequency resource from only one sector, and a collaboration mode of collaborating between sectors to transmit signals from both sectors. Any of the three modes is selected on the basis of measurement results of RSRP (Reference Signal Received Power) reported from a mobile station.
