Problems solved by technology

Since the SIB used to carry resource configuration information in 5G belongs to Other SI, at this time, the UE cannot read the resource pool configuration of the V2X service of the target cell before cell reselection, so the low-latency requirement of the V2X service cannot be met

Embodiment Construction

[0111] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0112] In 5G technology, system information is divided into minimum set system information (minimum SI) and other system information (OtherSI). Wherein, the minimum SI includes a master information block (Master Information Block, MIB) and SIB 1, and the base station will always broadcast the minimum SI. The Other SI includes all other remaining SIBs. The base station can selectively ...

Abstract

The disclosure relates to a system information sending and receiving method, device, equipment and system, and belongs to the communication field. The method includes: the terminal sends a system information request message to the first access network device, the system information request message carries an identifier of a neighboring cell and an identifier of a system information block SIB X, where X is an integer greater than 1; the terminal receives Other system information Other SI broadcast by the second access network device, where the Other SI carries the SIB X. In this disclosure, the UE sends a system information request message to the first access network device, the first access network device sends an update data message to the second access network device, the second access network device broadcasts the Other SI of the neighboring cell, and the Other The SI carries the SIB X used to configure transmission resources, so that the UE can read the SIB X of the neighboring cell in advance before performing cell reselection, thereby ensuring the low latency requirement of the terminal when transmitting service data.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a method, device, device and system for sending and receiving system information. Background technique [0002] In the long-term evolution (Long-Term Evolution, LTE), in order to support a vehicle to everything (V2X) service, a wireless resource configuration method based on a resource pool is introduced. Resource pools are divided into sending resource pools and receiving resource pools. The sending resource pool and the receiving resource pool respectively indicate the time and frequency ranges of wireless resources used for sending and receiving V2X services. [0003] An evolved base station (eNode B, eNB) may broadcast the V2X resource configuration of the cell in the cell broadcast information. In related technologies, the eNB broadcasts a system information block (SystemInformation Block, SIB) 21 to each user terminal (User Equipment, UE) in the cell, and the UE rea...
