Abstract
【解決手段】1つの構成では、過負荷インジケータは、セルのための少なくとも1つの同期信号と基準信号との間の位相差として送信され得る。別の構成では、過負荷インジケータは、セルのための少なくとも1つの同期信号の連続する送信の間の位相差として送信され得る。さらに別の構成では、過負荷インジケータは、上記過負荷インジケータを送信するための予約されたリソース上でセルによって送信され得る。さらに別の構成では、過負荷インジケータは、低再利用チャネルまたはブロードキャストチャネル上でセルによって送信され得る。全ての構成について、UEは、隣接セルから過負荷インジケータを受信し、各隣接セルについての過負荷インジケータに基づいて、その隣接セルの負荷を決定し、隣接セルの負荷に基づいて、そのUEの動作を制御することができる。
