Summary:To provide a method and a wireless transmit/receive unit (WTRU) for implementing an enhanced physical downlink control channel (ePDCCH) by a multiple carrier communication system.SOLUTION: A WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may monitor the ePDCCH resource on a particular sub-frame. The WTRU may derive an aggregation level for a sub-frame associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH. The WTRU may receive a reference signal, and may then determine the type of reference signal. The WTRU may perform a demodulation of a physical downlink shared channel (PDSCH) or the ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly, based on a location of one or more ePDCCH resources where the WTRU may receive DCI.SELECTED DRAWING: Figure 18 【課題】拡張物理ダウンリンク制御チャネル(ePDCCH)をマルチキャリア通信システムで実現する方法及びワイヤレス送信/受信ユニット(WTRU)を提供する。【解決手段】WTRUは、ePDCCHリソースを監視するための構成を受信し、この構成に基づき特定のサブフレームのePDCCHリソースを監視し、アグリゲーションレベル数NALに関連付けられているサブフレームに対するアグリゲーションレベルを導出し、ePDCCHを送信または監視し、基準信号を受信し、基準信号の種類を判定し、その決定されたタイプに基づき復調タイミングを使用して、物理ダウンリンク共有チャネル(PDSCH)又はePDCCHを復調する。ePDCCH又はPDSCHは、WTRUがDCIを受信する1又は複数のePDCCHリソースのロケーションに基づき復調基準タイミングを暗黙的に識別することによってさらに監視又は受信される。【選択図】図18
