The transmitter uniquely distributes a predetermined number of analog beams among the analog beams formed by the array antenna in correspondence to each of the predetermined number of OFDM symbols, and repeatedly allocates the predetermined number of analog beams distributed for each of the predetermined number of OFDM symbols by targeting the subcarriers within the corresponding OFDM symbol. The receiver receives a channel measurement instruction message, measures a channel state based on reference signals transmitted through the analog beams allocated for respective subcarriers, and feeds the channel state measurement result back to the transmitter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for transmission/reception in radio communication system","description":"A transmitter, a receiver, and a method for measuring a radio channel based on reference signals transmitted through a predetermined number of OFDM symbols by using multiple antennas in an ultra-high ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9603156","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.
