Abstract: Embodiments of the present invention provide a data sending and receiving method and device. The method includes: receiving a threshold; if a data volume of a packet to be sent is less than the threshold, sending the packet in a first data transmission manner; and if a data volume of the packet is greater than or equal to the threshold, sending the packet in a second data transmission manner. By adopting the technical solution of the present invention, a resource waste caused by transmitting small data in a data transmission manner used for transmitting a large packet in the prior art can be reduced, transmission efficiency of small data can be improved, and a transmission delay can be reduced.

Abstract: This application provides a method for transmitting feedback information for downlink data, a terminal, and a base station. The method includes: receiving, by a terminal from a base station, DCI used for downlink data group scheduling and location information of a first feedback resource, where the DCI is used to indicate a scheduling condition of each terminal in a scheduling group to which the terminal belongs; receiving, by the terminal according to the DCI, downlink data sent by the base station; and sending, by the terminal according to the scheduling condition, feedback information for the downlink data by using the feedback resource indicated by the location information of the first feedback resource.

Abstract: A method and device for transmitting information are provided, and transmission efficiency in a case of a low code rate is ensured. The method includes: determining the number of groups M and/or a group size N, where M is an integer greater than 1, and N is an integer greater than 1 or equal to 1; processing, according to M and/or N, an information stream to be grouped to obtain M groups of information streams to be sent; and sending, separately over M different time-frequency resources, the M groups of information streams to be sent, where the number of symbols in each time-frequency resource of the M different time-frequency resources is greater than 4.
