Problems solved by technology

[0004] However, when the number of terminal devices in the same cell is large, a large number of terminal devices may request to obtain the same SIB. When multiple terminal devices request to obtain the same SIB, the network side device needs to unicast a large number of repeated transmissions of the SIB. Still waste wireless resources

Abstract

The application provides a system message sending method, a system message acquisition method, network-side equipment and terminal equipment. The system message sending method comprises the followingsteps: the network-side equipment receives a first transmission request, wherein the first transmission request is used to request a first system message; if a first preset condition is met, the network-side equipment sends the first system message in a broadcast and / or multicast mode; and if the first preset condition is not met, the network-side equipment sends the first system message in a unicast mode. By adopting the method, the network-side equipment and the terminal equipment provided by the application, the amount of information of unicast can be greatly reduced, and the waste of wireless resources can be reduced.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a method for sending system messages, a method for obtaining them, network side equipment and terminal equipment. Background technique [0002] In a wireless communication system, after obtaining downlink synchronization with a cell through a cell search process, a terminal device needs to acquire a series of system information, such as transmission parameters or channel information, in order to work correctly in the cell. The system information (SI for short) is organized in a system information block (SIB for short), wherein each SIB may include a series of parameter sets related to a certain function. [0003] Due to the large number and types of terminal devices accessing the same cell, different types of terminal devices have different functions to realize their own functions. Since different terminal devices have different functions to be implemented, the sy...
