Problems solved by technology

[0004] However, if service preemption occurs, for example, when URLLC service comes when eMBB service has already started transmission or is about to start transmission, URLLC will preempt eMBB transmission time-frequency resources, causing the original eMBB service to fail when HARQ feedback Falsely assumes that eMBB data transmission is wrong, thus discarding useful URLLC data

Abstract

The disclosure relates to an HARQ feedback method and device, a method and device for sending indication information, a user equipment, a base station and a computer-readable storage medium. The HARQfeedback method comprises: receiving a first service data transmission sent by a base station, scheduling control data of the first service data transmission carrying indication information, and the indication information being used for explicitly indicating or implicitly indicating second service data seizing a transmission resource of the first service data or the second service data seizing a transmission resource position of the first service data; according to the indication information, reserving the second service data seizing the transmission resource in a buffer, and generating HARQ feedback information about the first service data; and sending the HARQ feedback information to the base station. In the embodiments of the present disclosure, by reserving in a buffer, according to indication information, second service data seizing a transmission resource, useful second service data will not be abandoned in the transmission process of the first service data.

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 method and device, a method and device for sending indication information, user equipment, a base station, and a computer-readable storage medium. Background technique [0002] With the development of communication technology, the fifth generation of mobile communication technology (5th Generation, 5G for short) appears. The current business types of 5G include at least enhanced Mobile Broadband (eMBB for short), massive Machine Type Communication (mMTC for short), and Ultra Reliable Low Latency Communication (Ultra Reliable Low Latency Communication for short). URLLC) and many other types. These services are all data services, but they have different requirements for latency and reliability. For example, URLLC services are used in fields that require low latency, such as Internet of Vehicles, and have high ...
