Zusammenfassung:	PROBLEM TO BE SOLVED: To present a signal structure for use in D2D communication.SOLUTION: A plurality of allocations of a plurality of time-frequency resources for D2D communication is received from the eNB, a D2D communication session with a second UE is established, a plurality of automatic gain controls (AGCs) are performed using preambles of a plurality of received D2D slots, and a plurality of D2D slots containing an indication of a transmission power level to be used for subsequent transmission by another UE is transmitted. D2D transmission to and from the second UE includes transmission of the plurality of D2D slots. Each of the plurality of D2D slots begins with a preamble and contains a plurality of OFDM or SC-FDM symbols.SELECTED DRAWING: Figure 2 【課題】Ｄ２Ｄ通信における使用のための信号構造を提示する。【解決手段】ｅＮＢからのＤ２Ｄ通信のための複数の時間周波数リソースの複数の割り当てを受信し、第２ＵＥとのＤ２Ｄ通信セッションを確立し、受信された複数のＤ２Ｄスロットのプリアンブルを使用して、複数の自動利得制御（ＡＧＣ）を実行し、他のＵＥによる後続の送信のために利用される送信パワーレベルの指標を含む複数のＤ２Ｄスロットを送信する。第２ＵＥへの及びからのＤ２Ｄ送信は、複数のＤ２Ｄスロットを送信することを含む。複数のＤ２Ｄスロットのそれぞれは、プリアンブルで始まり、複数のＯＦＤＭ又はＳＣ−ＦＤＭシンボルを含む。【選択図】図２
