The method includes: receiving, by a terminal device, a first downlink signal from a network device in a first time unit of a first carrier, where the first carrier is a TDD carrier; determining, based on the first time unit, a second time unit used to send first feedback information for the first downlink signal on a second carrier, where the second carrier is an FDD uplink carrier; and sending the first feedback information to the network device on the second last symbol and/or the last symbol of the second time unit of the second carrier. Feedback information for a downlink signal on the first carrier is sent on the second carrier, so that a requirement of sending an uplink signal on the first carrier by the terminal device is reduced, thereby improving data transmission efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal sending and receiving method, and apparatus","description":"A signal sending and receiving method and an apparatus is described.
