本公开的实施例涉及半导体装置、无线电终端装置、无线电通信系统以及无线电终端装置的通信方法。半导体装置包括:通信单元,该通信单元以第一发射周期接收帧,从接收到的帧解调控制信息,调制发射数据,并且以第二发射周期广播经调制的发射数据作为射频分组信号;周期确定单元,该周期确定单元基于车辆信息确定第二发射周期;以及发射和接收控制单元,该发射和接收控制单元基于控制信息和第二发射周期生成用于确定发射数据的发射定时的发射定时触发信号,并且与发射定时触发信号同步地将发射输出输出至通信单元。第二发射周期等于或长于第一发射周期。

    A semiconductor device includes a communication unit which receives a frame at a first transmission period, demodulates control information from a received frame, modulates transmission data, and broadcasts a modulated transmission data at a second transmission period as a radio frequency packet signal, a period determination unit which determines the second transmission period based on vehicle information, and a transmission and reception control unit which generates a transmission timing trigger signal for determining a transmission timing of the transmission data based on the control information and the second transmission period, and outputs the transmission data to the communication unit in synchronization with the transmission timing trigger signal. The second transmission period is equal to or longer than the first transmission period.
