Abstract: This application provides a method for transmitting hybrid automatic repeat request HARQ feedback information and a communications apparatus. A terminal device receives downlink data channels. Each of the downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups. The terminal device determines a first transmission resource based on first information including the transmission parameter groups, and sends, on the first transmission resource, HARQ feedback information corresponding to the downlink data channels, so that a plurality of pieces of HARQ feedback information can be smoothly fed back. This helps improve service transmission reliability.

Abstract: This application provides a data transmission method and apparatus. A terminal device sends first data to a network device in the nth time unit, where n is an integer greater than or equal to 0. The terminal device send second data to the network device when the terminal device does not receive the response message corresponding to the first data before the (n+k)th time unit, wherein the second data is new data which is different from the first data, where k is a positive integer. According to the data transmission method provided in some embodiments of this application, the terminal device may flexibly determine the transmission mode of the second data based on an actual situation, so as to reduce a transmission delay of uplink data and improve transmission reliability of the uplink data.

Abstract: This application provides a link failure detection method. A terminal device measures quality of radio links corresponding to reference signals in a set. When any one of the radio links is of poor quality, and not all of the radio links are of poor quality, the terminal device notifies a network device of the radio link of poor quality. After determining the radio link of poor quality, the network device does not send and/or receive communication data between the network device and the terminal device on the radio link of poor quality, or does not send and/or receive, on the radio link of poor quality, communication data that does not satisfy a service requirement.
