Abstract

Embodiments of the invention provide a data transmission method, a base station and a use device. The data transmission method comprises: the base station determines a code modulation level and the number of physical resource block pairs, selects a transmission big / small table from a first transmission block big / small table and a second transmission big / small table, and determines relative transmission block big / small TBS, to make the base station transmit data to UE based on the selected TBS in the second transmission block big / small table, thereby enhace coding rate.

Description

technical field

[0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method, a base station, and user equipment. Background technique

[0002] In the long-term evolution system version 8 (English full name: Long Term Evolution Release.8REL.8, referred to as LTE REL.8) to LTE REL.11 system, the channel from the base station to the user equipment (English full name: User Equipment, referred to as UE) The state determines the throughput from the base station to the UE. In a good channel state, the base station can transmit data to the UE using a higher level of coding and modulation (English full name: Modulation and Coding Scheme, MCS for short), and the throughput of the system is relatively low. In poor channel conditions, in order to control the bit error rate during data transmission, the base station can use a relatively low MCS level to transmit data to the UE. The encoding rate and MCS level used to ...
