Title: (EN) Downlink control information transmission method and detection method, base station and user equipment
(ZH) 下行控制信息发送方法、检测方法、基站及用户设备
Abstract: front page image
(EN) The invention provides a downlink control information transmission method and detection method, a base station and user equipment. The downlink control information detection method includes that the user equipment detects downlink control information which is carried by ePDCCH (Physical Downlink Control Channel) on resource blocks according to predefined information and a resource block set which is configured through the base station. The predefined information at least comprises sub-carrier position information which is detected in the resource block set, reinforced control channel unit information which is detected in the resource block set, mapping modes of the ePDCCH, aggregation level configuration information which is detected in the resource block set and the number of candidate sets which are corresponding to aggregation levels and downlink control information formats detected in the resource block set. According to the downlink control information detection method, the user equipment is flexibly indicated to detect the downlink control information which is carried by the ePDCCH on corresponding physical resource blocks according to the configured resource block set and the predefined information, so that resources for the user equipment to detect searching space are saved and the system dispatching efficiency is improved.
(ZH) 本发明提供了一种下行控制信息发送方法、检测方法、基站及用户设备,该检测方法包括:用户设备根据基站配置的资源块集合和预定义信息,在资源块上检测ePDCCH承载的下行控制信息;其中,预定义信息至少包括以下之一:资源块集合中检测的子载波位置信息、资源块集合中检测的增强控制信道单元信息、ePDCCH的映射模式、在资源块集合中检测的聚合等级配置信息、在资源块集合中所检测的聚合等级对应的候选集数量和下行控制信息格式。在本发明中,通过配置的资源块集合和预定义信息来灵活指示用户设备在相应的物理资源块上检测ePDCCH承载的下行控制信息,从而可以节省用户设备检测搜索空间的资源,提高了系统的调度效率。
