Abstract

The invention provides an information transmission method and device. The method comprises the following steps: at least one of the following is determined according to a preset mode and / or an eNB-configured mode: a precoding resource block group PRG, reference signals, frequency domain resource allocation granularity and information transmitted in a transmission time interval TTI. Via adoption of the above method, a problem that unreasonable data transmission is caused due to unreasonable setting of relevant parameters while short TTI technologies are adopted can be solved, and reasonable data transmission can be realized while the short TTI technologies are adopted.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information transmission method and device. Background technique [0002] The rapid development of mobile Internet and Internet of Things has triggered the explosive growth of data traffic and the widespread rise of diversified and differentiated services. As a new generation of mobile communication technology, 5G will support higher speed (Gbps), massive links (1M / Km2), ultra-low latency (1ms), higher reliability, and 100-fold energy efficiency improvement compared with 4G. Support new changes in demand. Among them, ultra-low latency, as a key indicator of 5G technology, directly affects the development of latency-limited services such as Internet of Vehicles, industrial automation, remote control, and smart grid. Currently, a series of standard research on 5G latency reduction is being gradually advanced. [0003] Transmission Time Interval (TTI) reduction is an importa...
