Abstract

The invention discloses a system information transmission method and device. The method includes: the terminal requests system information of the first network side device through dedicated control signaling, and the system information is system information that the terminal needs to use; the terminal receives the system information. In the embodiment of the present invention, based on its own needs, the terminal can request the system information of the network-side device from the network-side device through dedicated control signaling, so as to save the transmission resources used for transmitting system information, and avoid the base station in the prior art. The waste of transmission resources caused by transmitting system information by broadcasting.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for transmitting system information. Background technique [0002] In the existing LTE system, system information is periodically sent in a cell by broadcasting. No matter whether the terminal is in the connected state or the idle state, after establishing downlink synchronization with the cell, the terminal can obtain the relevant information of the cell by receiving the system information sent by the cell. [0003] However, since the terminal does not need to receive the system information of the cell after acquiring the system information of the cell. The manner in which a cell sends system information by broadcasting is a serious waste of transmission resources. Contents of the invention [0004] Embodiments of the present invention provide a method and device for transmitting system information, so as to save transmission resources used in transmitting syste...
