The method includes: a base station mapping enhanced resource element groups (eREGs) corresponding to an ePDCCH to different resource elements, wherein each of the eREGs corresponding to the ePDCCH is located in one physical resource block pair; and the base station sending the ePDCCH on the resource elements. The disclosure improves the reliability and resource utilization of ePDCCH transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for sending and receiving EPDCCH, base station, and user equipment","description":"Provided are a method and a device for sending and receiving an ePDCCH, a base station, and user equipment.
