Abstract

A system information sending method, a receiving method, a terminal and a base station, the system information sending method comprising, when applied to a base station side, dividing a geographic range covered by the base station into a plurality of geographic areas which are not overlapped with each other, and numbering each geographic area to obtain an area identifier of each geographic area; and broadcasting and sending system information, wherein the system information comprises regional system information of at least one geographic region. In the invention, the base station broadcasts the area system information for the specific geographic area, and the terminal can only receive the area system information of the geographic area where the terminal is located and does not receive the area system information of other geographic areas, so that the transmission efficiency of the system information can be improved, and the receiving power consumption overhead of the terminal is reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for sending and receiving system information, a terminal and a base station. Background technique [0002] In the fifth generation mobile communication (5G) system, each cell usually broadcasts system information. In order to achieve better cell reselection, the reselection-related parameters of neighboring cells are sent in the System Information Block (SIB) of the current serving cell, for example, in SIB3 (same frequency) / SIB4 (inter-frequency) / SIB5 (different system) and sent to the UE. In addition, in order to avoid ping-pong cell selection, related parameters of neighboring cells are also placed in SIB3 / SIB4 / SIB5. [0003] In the prior art, the system information of a certain cell needs to be broadcast in multiple neighboring cells through SIB3 / SIB4 / SIB5, and redundant signaling transmission reduces the resource utilization efficiency of the ...
