example 1

[0234] This example uses the method of sending and receiving the system information index by the UE to periodically broadcast and send the system information table through the network side equipment as an example. The specific workflow is as follows:

[0235] Step 1. UE1 receives the system information table periodically broadcasted by the network-side device, which includes periodically broadcast system information and on-demand system information. The content of the system information table periodically broadcasted by the network side device is relatively large, and the broadcast period is relatively long, such as 500ms, 1s, etc.

[0236] The system information table includes SI table index and SIAID list. Wherein, the SI table index is a first-level index, pointing to a group of system information and parameter configurations, for example, index1 corresponds to SIB1-SIB5. The effective area of ​​the system information table contains 2 SIAs, and the SIA ID list is {SIA ID1,...

example 2

[0240] In this example, the process of sending and receiving the system information index by the UE through the method of pre-configuring the system information table is illustrated as an example. The specific workflow is as follows:

[0241] Step 1. The system information table and default parameter configuration are defined in the 3GPP protocol. When the UE manufacturer implements it, the system information table has been pre-configured / pre-stored in the China Mobile customized machine UE2, which contains the system information periodically broadcast.

[0242] The system information table contains multiple sets of SI table indexes, pointing to the default system information and parameter configuration corresponding to China Mobile's PLMN. Wherein, SI table index is a secondary index, for example, index(1,2) corresponds to parameter configuration 2 of SIB1, and index(2,1) corresponds to parameter configuration 1 of SIB2.

[0243] Step 2. The SI table index is periodically bro...

example 3

[0246] In this example, the process of sending and receiving the system information index by the UE obtaining the system information table through a request / response is illustrated as an example. The specific workflow is as follows:

[0247] Step 1. UE3 obtains the resources requested by the system information table from the system information periodically broadcast by the network side, and obtains the system information table from the network side through a request / response method, which contains on-demand system information.

[0248] The system information table includes SI table index and SI table ID. Wherein, the SI table index is a first-level index, pointing to a set of system information and parameter configuration, for example, index2 corresponds to SIB1-SIB8. The SI table ID is used to identify the valid area of ​​the system information table. For example, SI table ID1, TRP1 and TRP2 in the valid area of ​​the system information table have the same SI table ID1, and T...

Abstract

The present invention provides a method for acquiring system information, a user terminal, and a network-side device. The method may include: the user terminal receives a system information table index sent by the network-side device; The system information table acquires system information, wherein the system information table includes system information table index, system information and parameter configuration of system information. The embodiments of the present invention can reduce system information overhead.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a system information acquisition method, a user terminal and a network side device. Background technique [0002] The system information (SI, System Information) of the wireless communication system is mainly divided into a master information block (MIB, Master Information Block) and a plurality of system information blocks (SIBs, System Information Blocks), wherein the system information block may include SIB1-SIB20 system message. In practical applications, system information needs to be broadcasted in many scenarios, for example, when the UE newly accesses a cell or the broadcast message changes, the system information will be broadcasted. At present, each broadcast broadcasts all system information, including system information such as MIB, SIB1 and SI, wherein SI includes SIB2-SIB20, and of course, it may continue to expand. Since the system information i...
