一种增强控制信道单元E-CCE资源映射方法及设备
摘要：
本发明公开了一种增强控制信道单元E-CCE资源映射方法及设备，所述方法包括：针对各下行子帧中的任一物理资源块对PRB part，确定该PRB part的非控制域中未被该PRB part的已有导频所占用的资源单元RE，并从确定的RE中选取多个RE作为该下行子帧的E-CCE。由于在本发明所述方案中，E-CCE所占用的RE与该E-CCE所在PRB part的已有导频所占用的RE不重叠，从而解决了现有技术中存在的、由于E-CCE与已有导频存在RE重叠而导致的终端在未接收到额外信令通知的情况下无法正确接收和解码增强物理下行控制信道的问题。
摘要（英）：

The invention discloses a method and device for resource mapping of an E-CCE. The method for the resource mapping of the E-CCE comprises the steps that for any PRB pair in each downlink subframe, REs which are not occupied by the existing pilot frequency of the PRB pair and located in an area not controlled by the PRB pair are determined, and multiple REs are selected from the determined REs to serve as the E-CCE of the subframe. According to the method and device for the resource mapping of the E-CCE, due to the fact that the REs occupied by the E-CCE do not overlap with the REs occupied by the existing pilot frequency of the PRB pair where the E-CCE belongs, and the problem that according to the prior art, due to the fact that REs occupied by the E-CCE overlaps with REs occupied by the existing pilot frequency, a terminal can not receive and decode an enhanced-physical downlink control channel accurately under the condition that no extra signaling message is received by the terminal is solved.
