Problems solved by technology

In the 5G scenario, since the evolved base station or 5G base station (such as a high-frequency base station) has few users or even no users in many cases, if the base station is still broadcasting all system information blocks, it is a big problem. Waste of resources, so it is proposed to optimize the processing method of system information

Embodiment 1

[0089] figure 1 It is a flow chart of a method for processing system information provided in Embodiment 1 of the present invention. The method for processing system information in this embodiment is applied to the terminal, as shown in figure 1 As shown, the method for processing system information includes the following steps:

[0090] Step S101: The terminal sends the preamble to the base station at the time domain position corresponding to the required first system information block according to the corresponding relationship between various first system information blocks and the time domain position where the preamble is sent;

[0091] Step S102: the terminal receives the required first system information block sent by the base station.

[0092] According to the above method for processing system information, the terminal sends a preamble to the base station at the position in the time domain corresponding to the required first system information block, and then informs ...

Embodiment 2

[0104] figure 2 It is a flow chart of a method for processing system information provided in Embodiment 2 of the present invention. The method for processing system information in this embodiment is applied to the base station, as shown in figure 2 As shown, the method for processing system information includes the following steps:

[0105] Step S201: The base station receives the preamble sent by the terminal, and determines the first system information block required by the terminal according to the corresponding relationship between various first system information blocks and the time domain positions where the preamble is sent, and the time domain position where the terminal sends the preamble. system information block;

[0106] Step S202: the base station sends the required first system information block to the terminal.

[0107] According to the method for processing system information in this embodiment, the base station can obtain the first system information block...

Abstract

The invention discloses a method, device and system for processing system information. A base station sends a second system information block with key information. A terminal feeds back a first systeminformation block required by the terminal to the base station in a preamble mode according to the second system information block sent by the base station and information preset in the terminal. Thebase station sends the information block required by the terminal to the terminal according to a time domain position of a preamble. In this way, a system information processing mode is optimized andthe first system information block which is not received by the terminal is prevented from being broadcasted by the base station, so resources are saved, and the performance of the whole system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for processing system information. Background technique [0002] In the Long Term Evolution (LTE for short), in order to guide the behavior of the terminal in the idle state, the base station broadcasts part of the configuration information through the system information, and the terminal performs the idle state behavior according to the configuration information carried in the system information after receiving it. System information can be divided into multiple information blocks according to features and functions, among which important information blocks, such as Master Information Block (MIB for short) and System Information Block Type 1 (SIB1 for short) are in fixed Transmission is performed on time domain and frequency domain resources. The MIB has a fixed sending period of 40 milliseconds, and the MIB is repeatedly sent in subframe 0 of each ...
