The method includes: sending a reference signal on an invalid subframe. The method further includes: in a guard band mode, if a downlink timeslot of a special subframe includes N downlink symbols, determining to send the reference signal on the N downlink symbols. The method further includes:mapping and spreading a code word on a preset number of subframes or resource units for sending the mapped and spread code word. The method further includes: sending the reference signal on an orthogonal frequency division multiplexing (OFDM) symbol, where a resource element other than a resource element where the reference signal is located on the OFDM symbol is a muting resource element, and no data is mapped or sent on the muting resource element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal sending method and apparatus, signal receiving method and apparatus, and computer storage medium","description":"Provided are signal sending method and apparatus, and a computer storage medium.
