Abstract

The invention provides a data transmission method and apparatus, and belongs to the technical field of wireless communication. The method includes the following steps: receiving objective indicating information which is transmitted by a base station; based on the objective indicating information, determining the transmission directions of n transmission units, wherein the transmission directions include uplink directions and downlink directions, n is a positive integer which is greater than or equal to 1; and in accordance with the transmission directions indicated by the objective indicating information, transmitting data through the n transmission units. According to the invention, the method herein can flexibly determine the transmission direction of a transmission unit, such that the transmission direction can have dynamic changes over the data transmission of a communication system, and the demands for dynamic changes of the transmission direction of the new generation of communication systems can be met.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a data transmission method and device. Background technique [0002] In practical applications, wireless communication systems generally transmit data in the form of data frames, where the transmission directions of different subframes in a data frame can be different, that is, the transmission directions of some subframes in a data frame can be downlink The transmission direction of some subframes can be the uplink direction. In the subframes whose transmission direction is the downlink direction, the terminal can receive the data sent by the base station, and in the subframes whose transmission direction is the uplink direction, the terminal can send data to the base station. In order to ensure normal data transmission between the terminal and the base station, the terminal and the base station need to agree on the transmission direction of each subframe in th...
