Scheduling method and device of system information and terminal

Abstract

The invention discloses a scheduling method of system information. The method comprises the following steps that: a terminal acquires scheduling information of the most frequently scheduled unit (SU-1) and receives complete information of the (SU-1) according to the scheduling information; the terminal acquires dynamically scheduled window information and receives the information of other scheduled units (SU-n) according to the window information, wherein n>1; a terminal acquires mapping information of a system information block (SIB) and a scheduling unit (SU) from the information of the (SU-1) and acquires all system information according to a corresponding relation between the SIB and the SU indicated by the mapping information. The invention also discloses a system information scheduling device and a terminal, so UE (user equipment) can receive the (SU-1) correctly, and further receive the complete system information correctly and effectively.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a system information scheduling method, device and terminal. Background technique [0002] In a cellular system, system information (SI, System Information) refers to public information of a certain cell or multiple cells. Since the SI has many contents, it is divided into system information blocks (SIB, System Information Block) according to characteristics, and each SIB contains SI of the same characteristic. For example, SIB-1 mainly includes timer and counter parameter information of user equipment (UE, User Equipment) in idle mode. [0003] Usually in a terrestrial wireless access network (UMTS, Universal Mobile Telecommunications System), the structure of the system information is a tree, such as figure 1 As shown, the root node is a master information block (MIB, Master Information Block), and the MIB includes one or two scheduling blocks (SB, Scheduling B...

AI Technical Summary

Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found through research that in the prior art scheme, although the period and position of SU-1 are fixed, it does not indicate whether SU-1 can transmit in one subframe or multiple subframes

If SU-1 is only sent on one subframe, then no SU-1 scheduling information is required; if SU-1 is sent on multiple consecutive or non-consecutive subframes, then SU-1 needs to have scheduling information indication , otherwise the UE will not be able to receive SU-1 correctly because it cannot obtain the scheduling information of SU-1

In addition, although a dynamic scheduling mechanism is determined for SUs other than SU-1 in the existing technical solution, there is no specific implementation plan for the specific scheduling information and how to indicate it.

In addition, although there is an information element of the mapping information of SIB and SU in the current agreement, the specific content of the mapping information is not
