Title: (EN) Downlink control information transmitting method, detecting method, base station and user equipment
Abstract: front page image
(EN)

A method for transmitting downlink control information, a detecting method, a base station and a UE are provided in the present invention. The detecting method includes: the UE detects downlink control information beared by ePDCCH in a resource block according to a resource block set and pre-defined information configured by the base station; wherein the pre-defined information at least includes one of the followings: sub-carrier position information detected in the resource block set, enhanced control channel unit information detected in the resource block set, a mapping mode of the ePDCCH, aggregation level configuration information detected in the resource block set, the amount of candidate set corresponding to the detected aggregation level in the resource block set and a downlink control information format. In the present invention, the UE is agilely indicated to detected the downlink control information beared by the ePDCCH in the corresponding physical resource block according to the configured resource block set and the pre-defined information, so as to save resources of space detected and searched by the UE, thus scheduling efficient of the system is improved.
