A method for the reception of a physical downlink shared channel (PDSCH) signal by a terminal in a wireless communication system, according to one embodiment of the present invention, can comprise: a step for determining a start symbol index for the PDSCH in a downlink subframe; and a step for receiving the PDSCH signal on the basis of the start symbol index. The PDSCH start symbol index (k) when the downlink subframe belongs to a specific subframe set is determined according to k=min(KThreshold, K), KThreshold being a prescribed threshold, K being the PDSCH start symbol index when the downlink subframe does not belong to the specific subframe set, and min(KThreshold, K) being the minimum value among KThreshold and K."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Downlink signal transceiving method and device, in wireless communication system, taking into account antenna port relationship","description":"The present invention relates to a wireless communication system, and more particularly, to a downlink signal transmission and reception method and device taking into account antenna port relationship","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9648607","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.
