Problems solved by technology

[0004] With the enhancement of terminal capabilities, the terminal can have stronger processing capabilities. In this case, the terminal can perform ACK or NACK feedback on the received data faster to reduce the delay of data transmission. This is for some It is important for services with high delay requirements, such as URLLC services, and the traditional HARQ timing feedback method is no longer suitable for this scenario

Abstract

The present invention relates to an HARQ (Hybrid Automatic Repeat reQuest) feedback indication, an HARQ feedback method and apparatus, a base station, user equipment, and a computer readable storage medium. The HARQ feedback indication method includes the steps: adding a timing relationship between a time domain unit where the current downlink data is located and a time domain unit of the uplink HARQ feedback of the current downlink data to the control information; and sending the current downlink data and the control information with the added timing information to the terminal. By adding thetiming relationship between the time domain unit where the current downlink data is located and the time domain unit of the uplink HARQ feedback of the current downlink data to the control information and by sending the current downlink data and the control information with the added timing information to the terminal, the HARQ feedback indication method enables the terminal to send the uplink HARQ feedback information of the current downlink data to the base station according to the timing relationship, so as to implement dynamic HARQ feedback.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a Hybrid Automatic Repeat Request (HARQ) feedback indication, a feedback method and device, a base station, a user equipment, and a computer-readable storage medium. Background technique [0002] The continuous emergence of new Internet applications such as a new generation of augmented reality technology (Augmented Reality, referred to as AR), virtual reality (Virtual Reality, referred to as VR) and vehicle-to-vehicle communication has put forward higher requirements for wireless communication technology, driving the continuous evolution of wireless communication technology. meet the needs of the application. At present, cellular mobile communication technology is in the evolution stage of a new generation of technology. An important feature of the new generation technology is to support flexible configuration of various business types. Because different ...
