    • PROBLEM TO BE SOLVED: To provide a communication terminal apparatus and a wireless communication method that exhibit a shorter time period required, until a start of communication and causes the throughput in the wireless communication system to be less likely to be reduced. SOLUTION: When the number of transmission notified by a response determining part 107 is zero, a subchannel in use selecting part 108 selects a subchannel which exhibits the highest-order sub-channel of the reception qualities of the subchannels notified by a reception quality measuring part 106 and then notifies the selected subchannel to a subchannel allocating part 113. In addition, when the notified number of retransmissions is one or more, a subchannel which exhibits lower order reception quality than the highest-order reception quality by the informed number of retransmissions is selected based on the reception qualities of the subchannels notified by the reception quality measuring part 106 for a pilot signal, received after a transmission of the latest access request signal, and then the selected subchannel is notified to the subchannel allocating part 113.

    • 要解决的问题:提供一种通信终端装置和无线通信方法,其显示所需的较短时间,直到通信开始,并且使得无线通信系统中的吞吐量不太可能降低。 解决方案:当由响应确定部分107通知的发送次数为零时,使用选择部分108中的子信道选择表示由接收所通知的子信道的接收质量的最高次子信道的子信道 质量测量部分106,然后将所选择的子信道通知给子信道分配部分113.另外,当所通知的重传次数是一个或多个时,通过通知号码表现出比最高接收质量低的接收质量的子信道 基于由接收质量测量部分106通知的用于在发送最新的访问请求信号之后接收的导频信号的子信道的接收质量来选择重传,然后将所选择的子信道通知给子信道分配部分113。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide an in-vehicle apparatus remote control system capable of properly setting a detection area of a portable machine by a transmitter inside the vehicle. SOLUTION: A vehicle 10 is provided with a reference LF receiver 9 set in an outer edge position of a desirable in-vehicle detection area and the reference LF receiver 9 receiving signals transmitted from the in-vehicle LF transmitter 2e. A signal transmitting output level of the in-vehicle LF transmitter 2e is adjusted on the basis of the receiving result in the reference LF receiver 9. Hence, the detection area, a range of arrival of a request signal transmitted from the inside of the vehicle LF transmitter 2e is varied at every vehicle or even if the detection area is varied in correspondence with an electromagnetic wave environment wherein the vehicle 10 is located, a signal transmitting output inside the vehicle LF transmitter 2e can be so adjusted that the required detection area can be always obtained.

    • 要解决的问题:提供能够通过车辆内部的发射机适当地设定便携式机器的检测区域的车载装置遥控系统。 解决方案:车辆10设置有设置在所需车载检测区域的外边缘位置的参考LF接收器9和接收从车载LF发送器2e发送的信号的参考LF接收器9。 基于参考LF接收机9的接收结果,调整车载LF发送机2e的信号发送输出电平。因此,检测区域是从车内发送的请求信号的到达范围 LF发送器2e在每个车辆上变化,或者即使检测区域与车辆10所在的电磁波环境相对应地变化,也可以调整车辆LF发送器2e内的信号发送输出,使得所需检测区域可以 总是得到。 版权所有(C)2006,JPO&NCIPI
