AI Technical Summary

Problems solved by technology

[0003] At present, in the non-dynamic scheduling process, since the network device cannot know the size of the data to be sent by the terminal in advance, there may be a problem that the resource size indicated by the network device does not match the actual size of the data to be sent by the terminal. If the resources are too large, the actual data to be sent by the terminal cannot completely fill the resource indicated by the network device, and padding bits need to be sent to fill it up. More Padding will cause the terminal to generate additional uplink transmission duration, resulting in longer More energy consumption, but also reduce the utilization of air interface resources

Abstract

The present application provides a method and apparatus for transmitting data. The method includes: receiving an uplink grant message from a network device, where the uplink grant message includes first information, and the first information corresponds to multiple transport block sizes; A piece of information determines the multiple transport block sizes; determines a first transport block size from the multiple transport block sizes according to the size of the data to be sent; sends the to-be-sent data to the network device according to the first transport block size. The data transmission method according to the embodiment of the present application helps to improve the utilization rate of air interface resources and the reliability of data transmission.

Description

Technical field [0001] This application involves the field of communication and more specific, involving a method and device that transmits data. Background technique [0002] The third -generation partner program 3GPP (The Third Generation Partnership Project (3GPP) is summarized as the following three types of typical scenarios for 5G: enhanced mobile broadband (EMBB) business. , MMTC) business and ultra-reliable low latency communication (Ultra-Reliable and Low Latence Communications (URLLC) business, the URLLC is for the reliability of data transmission and demanded harsh business scenes, such as networking, industrial control and other scenarios, as well as In the future, virtual reality (VR), new businesses such as Augmented Reality (AR), how to improve the reliability of data transmission in the data transmission process into a new problem of URLLC business during the data transmission process. [0003] At present, during the non -dynamic scheduling process, because the ne...
