Abstract

An embodiment of the present invention provides a data transmission method, a base station, and a user equipment. The data transmission method includes determining the coding modulation level and time-frequency resource by the base station, and determining the TBS index and modulation mode in the first or second modulation and transmission block size index table. , the second TBS index is not less than the first TBS index, and the selected TBS is used to send service data and system scheduling control signals to the user equipment, so that the base station can select a larger TBS to achieve a higher coding rate and improve system throughput.

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 ...
