Abstract

The invention discloses a system information transmission method, a base station, and a terminal. The method comprises the following steps: sending minimum system information carrying preset corresponding relationship information to the terminal; and receiving a first random access message MSG1 sent by the terminal according to the minimum system information, wherein the MSG1 is used for requesting other system information, and the preset corresponding relationship is a corresponding relationship between the other system information that is allowed to be requested by the MSG1 and a random access resource. According to the system information transmission method disclosed by the invention, the base station sends the corresponding relationship between the other system information that is allowed to be requested by the MSG1 and the random access resource to the terminal through the minimum system information, and when the other system information needing to be requested by the terminal belongs to the system information in the corresponding relationship, the terminal sends the MSG1 to the base station through the random access resource in the corresponding relationship so as to requestthe corresponding other system information, therefore the request configuration problem of the other system information is solved, and the request of the other system information by the terminal is achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method for transmitting system information, a base station and a terminal. Background technique [0002] In order to reduce signaling overhead, improve wireless resource utilization, and reduce base station energy consumption, the fifth-generation communication system (5G system) proposes to divide system information into two categories, one of which is Minimum System Information (MSI), The other type is other system information (other System Information, other SI), where other SI includes all system information except Minimum SI. Further, the base station sends the minimum system information MSI to the terminal UE in a periodic broadcast manner. The UE may determine which message is used to request the Other SI from the base station according to the configuration information in the minimum system information of the base station. [0003] Among them, in the ...
