摘要： A position calculation method that calculates the correct position of a terminal even when errors are not distributed symmetrically for positive and negative values, by calculating the position of a terminal using the delay time of received signals. The method calculates a first range that is a difference between a range from the terminal to each of antenna and a range from the terminal to a base antenna, the range being calculated from a wireless signal delay time; calculates a second range that is a difference between a range from an assumed terminal position for calculation to each antenna and a range from the assumed terminal position for calculation to the base antenna; calculates a likelihood of the position of the terminal, repeats these procedures to obtain a point where the likelihood is maximized, and determines an obtained most likely solution as the position of the terminal.

摘要： A base station performs an association between frequency range and combinations of a plurality of base stations including an local base station to notify a terminal of the association. According to the notified association, the terminal, for each frequency, calculates quality of communication with one base station or quality of communication with the combination of the plurality of base stations. The base station and the control station determine the base station/the plurality of base stations that communicate with the terminal, the wireless resource and the transmission scheme, based on the result. Further, the base station selects whether to notify an entirety of or a part of the association to the terminal using positional information of the terminal. Since the association information that is unnecessary for the terminal is not communicated, it is possible to further lighten the load of control.

摘要： In a wireless communication system, when data communication is performed between a relay device and a terminal (in a second path), the same amount of data is required to be transferred between a base station and the relay device (in a third path). An amount of wireless communication resources required is obtained by adding an amount inversely proportional to a capacity of each of the second and third wireless transmission-paths. Therefore, the amount inversely proportional to the capacity of the third path is consumed in excess. Based on a channel quality of a first wireless channel between the base station and the terminal, a channel quality of a second wireless channel between the terminal and the relay station, and a channel quality of a third wireless channel between the base station and the relay station, it is determined whether data communication between the base station and the terminal is relayed.
摘要翻译：在无线通信系统中，当在中继装置与终端（第二路径）之间进行数据通信时，需要在基站与中继装置（第3路径）之间传送相同数量的数据。通过添加与第二和第三无线传输路径中的每一个的容量成反比的量来获得所需的无线通信资源量。因此，与第三路径的容量成反比的量被消耗。基于基站和终端之间的第一无线信道的信道质量，终端和中继站之间的第二无线信道的信道质量以及基站和中继站之间的第三无线信道的信道质量确定基站和终端之间的数据通信是否被中继。
