Abstract

The present application provides an information transmission method and device, which relate to the field of wireless communication technology, and are used to solve the problem that the existing technology cannot meet the requirements of future networks caused by only supporting single-hop relay (RN) network access. In this method, the first device receives a first message sent by the base station, the first message includes first indication information and system information, and the first indication information is used to determine whether to broadcast the system information; the first device determines according to the first indication information Need to broadcast system information, broadcast system information. In this application, the first message of the base station carries the first indication information, so that after receiving the first message, the first device can determine the broadcast system information according to the first indication information, which facilitates the target device receiving the system information to pass through the system. The information is connected to the base station to realize a multi-hop relay network, and the method provided in this application can be applied to build a multi-hop relay network.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an information transmission method and device. Background technique [0002] Compared with the fourth generation mobile communication system (4G), the fifth-generation mobile communication system (5G) has more stringent requirements on network performance indicators. For example, the capacity index has been increased by 1000 times, wider coverage requirements, ultra-high reliability and ultra-low latency, etc. On the one hand, due to the abundance of high-frequency carrier frequency resources, in hotspot areas, in order to meet the demand for 5G ultra-high capacity, it is more and more popular to use high-frequency small cell networking. In order to solve the problems of poor propagation characteristics of high-frequency carriers, serious attenuation due to occlusion, and limited coverage, it is usually necessary to deploy a large number of densely p...
