Abstract

Embodiments of the present invention provide a transmission method, network equipment, terminal equipment, and system for transmission mode information, and relate to the field of communication. The method includes: determining information of at least two downlink transmission modes, and at least two downlink transmission modes The first downlink transmission mode is used for downlink data transmission whose time unit is the first transmission time interval TTI, and the second downlink transmission mode is used for downlink data transmission whose time unit is the second TTI, and the lengths of the first TTI and the second TTI are different . Send the information of at least two downlink transmission modes to the terminal device. In the present invention, by configuring at least two downlink transmission modes, the first downlink transmission mode and the second downlink transmission mode in the at least two downlink transmission modes correspond to TTIs with different lengths, so as to solve the PDSCH with different TTI lengths in the related art The problem of low flexibility when the transmission is scheduled. The effect of improving the flexibility of scheduling during data transmission is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting information in a transmission mode, a network device, a terminal device and a system. Background technique [0002] The transmission of service data in various communication systems is usually performed based on the scheduling of network equipment, and the time unit of network equipment scheduling is a transmission time interval (English: Transmission Time Interval; TTI for short). The shorter the length of the TTI is, the shorter the round-trip time (English: Round-Trip Time; RTT for short) of data transmission will be. With the development of technology, people hope that the RTT will be smaller and smaller, which introduces the short TTI transmission technology, that is, the length of the TTI can be set to be shorter than the traditional TTI during network device scheduling. Among them, RTT is a key performance indicator (English: Key Performance Ind...
