移动通信系统，通信控制方法，基站和移动台要采用相同的方式

Mobile communication system, communication control method, and base station and mobile station to be employed in the same
Abstract:
In the communication system performing transmission with generating the vacant period in the slotted mode during data transmission in order to perform various process, such as different frequency carrier quality measurement or so forth, the control signal for maintaining a communication quality is inserted even in the vacant period. Therefore, a link quality may not be degraded even if the vacant period is long. Namely, when the pilot signal is used as the control signal, even in the vacant period, measurement of the link quality of the forward link with the pilot signal is performed in the mobile station to report the result of measurement to the base station. Therefore, transmission power control of the forward link can be performed according to the report in the base station. Therefore, degradation of the forward link can be eliminated.
Abstract(Chinese):

在进行传输的通信系统中，在数据传输期间以时隙模式生成空闲周期，以执行诸如不同的载波质量测量等的各种处理，即使在空闲时也插入用于维持通信质量的控制信号 期。 因此，即使空闲时间长，链路质量也不会降低。 也就是说，在导频信号被用作控制信号时，即使在空闲时段中，在移动台中执行与导频信号的前向链路的链路质量的测量，以向基站报告测量结果。 因此，可以根据基站中的报告来执行前向链路的发送功率控制。 因此，可以消除前向链路的劣化。
