Abstract

Disclosed are a data transmission method and a communication device. The method comprises: determining transmission parameters for transmitting a current target transmission block, the transmission parameters comprising a target modulation and coding scheme (MCS), the number of target physical resource blocks (PRBs) and information about PRB resource overhead; determining a target transport blocksize TBS of the target transport block according to the transmission parameter; and sending the target transmission block or receiving the target transmission block according to the target TBS. In this way, the information of the TBS used for data transmission can be determined based on different resource overheads.

Description

[0001] This application is a part of the invention patent application whose Chinese application number is 201780081671.7 (corresponding to PCT international application number PCT / CN2017 / 070326), the application date is January 5, 2017, and the invention title is "Data Transmission Method and Communication Device" case application. technical field [0002] The embodiments of the present application relate to the field of wireless communication, and more particularly, to a method and a communication device for transmitting data. Background technique [0003] In a Long Term Evolution (Long Term Evolution, referred to as "LTE") system, when scheduling data transmission, the network side will carry a Modulation and Coding Scheme (Modulation and Coding Scheme) in Downlink Control Information (Downlink Control Information, referred to as "DCI"). referred to as "MCS"). At the same time, the network side and the terminal side will pre-agreed the mapping relationship between the MCS...
