摘要： In a cellular radio communication system, a base station or a mobile station has a TA (Time Alignment)-range-out detection function, so that when a TA-range-out state that is unable to compensate with a guard interval is detected, the transmission condition of an uplink signal at the mobile station is changed by the mobile station autonomously or by the base station and the mobile station cooperatively.

摘要： A discontinuous change in a transmission timing in a time domain, which is caused by a transmission timing adjustment processing of an OFDMA uplink or the like, brings about a discontinuous rotation of a signal phase in a frequency domain, resulting in reduced communication quality. A wireless communication system of the present invention allows the signal phase of the frequency domain in a receiving station to be continuous before and after the timing adjustment processings by controlling a signal sequence in a transmission signal after conversion in the time domain in synchronization with the timing adjustment processing.
摘要翻译：由OFDMA上行链路等的发送定时调整处理引起的时域中的发送定时的不连续变化导致频域中的信号相位的不连续旋转，导致通信质量降低。本发明的无线通信系统允许接收站中的频域的信号相位在定时调整处理之前和之后是连续的，通过在与定时同步的时域中的时域中的转换之后控制发送信号中的发送信号中的信号序列调整处理。

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： 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.
