Abstract

The invention provides an information feedback method, a base station and a terminal. The information feedback method includes the following steps: sending downlink control information to a terminal, wherein the downlink control information includes indication information used to indicate the terminal to perform information feedback, and the indication information includes at least one of the following information: the delay of feedback information fed back by the terminal, whether the terminal listens before talk during feedback of feedback information, the type of listen-before-talk by the terminal during feedback of feedback information, and the parameter configuration of listen-before-talk by the terminal during feedback of feedback information; and receiving feedback information sent by the terminal according to the indication information in the downlink control information. The downlink control information sent by the base station to the terminal indicates feedback information of the terminal, and the terminal sends feedback information according to the indication. Therefore, the base station can receive the feedback information of the terminal accurately, and the reliability of communication between the base station and the terminal is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an information feedback method, a base station and a terminal. Background technique [0002] With the continuous emergence and enrichment of new business requirements, higher performance requirements are put forward for future mobile communication systems, such as higher peak rates, better user experience rates, smaller delays, and higher reliability , higher spectrum efficiency and higher energy efficiency, etc., and need to support more user access and use various business types. In order to support a huge number of various terminal connections and different types of services, the flexible configuration of uplink and downlink resources has become a major trend in technology development. Future system resources can be divided into different subbands according to different services, and transmission time intervals (Transmission Time Interval, TTI) of different lengths can...
