| Abstract(in English) | In 5G systems, the utilization of high frequency band that can use a wide bandwidth is expected. Generally, there is a problem that the communication area is narrow in the high frequency band. In order to utilize the small cells with high frequency band, we are studying the terminal-to-terminal (D2D) relay communication. The interference in D2D can reduced by controlling radio resources. However, the Control Channel Element (CCE) which is a radio resource necessary for the control signal increases in proportion to the number of terminals. When the CCE is exhausted, the communication quality deteriorates as transmission delay. Therefore, the problem is to reduce the number of CCEs when a large number of terminals exists. In this paper, we propose a method to reduce the number of CCEs by the grouping multiple D2D terminals without interference and multicasting the control signals. The effect of reducing the number of CCEs by the proposed method is evaluated by simulation. We confirmed that the proposed method has the effect of reducing the number of CCEs by about 71% at the maximum compared to mode 1. |
