Problems solved by technology

[0005] An application scenario of the eURLLC service is an industrial application. There are a large number of UEs in this scenario. If waiting for scheduling to meet the retransmission requirements, it will increase the waste of scheduling resources on the one hand, and on the other hand, in the process of waiting for scheduling It will bring a large delay, and it is difficult to meet the transmission delay requirements of eURLLC

Abstract

The present disclosure relates to a data feedback method and apparatus, a data transmission method and apparatus, a base station, a user equipment, and a computer-readable storage medium. The data feedback method includes: configuring a control channel for the user equipment UE, where the control channel is used to carry feedback information of physical uplink shared channel PUSCH data sent by the UE; and sending the feedback information to the UE through the control channel. In the embodiment of the present disclosure, by configuring a control channel for the UE, and sending feedback information to the UE through the control channel, the UE can quickly determine whether to retransmit the PUSCH data according to the feedback information, so that under the condition of ensuring the quality of data transmission, in the specified Complete data transmission within time to meet service transmission delay requirements.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data feedback method and apparatus, a data transmission method and apparatus, 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 (AR), Virtual Reality (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 types of services. Because different service types have different requirements for wireless communication technology, for ...
