In the method, when a current subframe needs to send downlink control information to a terminal by adopting a frequency domain distributed transmission mode, a base station selects, according to the current aggregation level, at least one available distributed E-CCE in a distributed E-PDCCH time frequency resource area of the current subframe, and uses the selected distributed E-CCE to send the downlink control information to the terminal. The present application solves the problem of how to transmit downlink control information through the E-PDCCH."},"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 detecting enhanced physical downlink control channel","description":"Disclosed are a method and a device for sending and detecting an enhanced physical downlink control channel (E-PDCCH), relating to the field of wireless communications, and used for solving the proble","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9603138","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
