example 1

[0218] Example 1, refer to Figure 5d , taking four resource configurations requesting system information as an example, the resource configuration d-1 requesting system information corresponds to the system information d-1 of NR, and the resource configuration d-2 requesting system information corresponds to the system information d-2 of NR 2. The resource configuration d-3 of the requested system information corresponds to the system information d-3 of the NR, and the resource configuration d-4 of the requested system information corresponds to all the system information of the LTE.

example 2

[0219] Example 2, a resource configuration requesting system information corresponds to all system information of a communication standard. If there are two resource configurations requesting system information, it can be defined: one resource configuration requesting system information corresponds to all system information of the first communication standard, and the other resource configuration requesting system information corresponds to all systems of the second communication standard information. like Figure 5e As shown, resource configuration e-1 requesting system information corresponds to all system information of NR, and resource configuration e-2 requesting system information corresponds to all system information of LTE.

[0220] In case 1.3, a resource configuration requesting system information corresponds to one or more or all system information related to a service. like Figure 5f As shown, taking the V2X service and configuring three resource configurations...

example 3

[0280] Example 3, the RRC signaling may include the information of the communication standard of the requested system information, that is, the unit of the request is the communication standard. The terminal device sends the requested communication system corresponding to the first system information to the network device through the RRC signaling. Correspondingly, after receiving the RRC signaling, the network device may send the first system information to the terminal device. Exemplarily, if the RRC signaling can be defined as NR, the network device sends system information of all NRs to the terminal device after receiving the RRC signaling.

Abstract

The invention provides a communication method and device and a storage medium, and the method comprises the steps that a first communication device sends a first message to a second communication device, the first communication device receives first system information from the second communication device, the first message comprises first information, and the first information is used for indicating the first communication device to request the first system information; when the terminal equipment needs the first system information, a first message can be sent to the network equipment to request the network equipment to send the first system information, so that the first communication device can acquire the first system information.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, device and storage medium. Background technique [0002] In a wireless communication system, when a terminal device needs certain system information and no valid version of the system information is currently stored, the terminal device needs to acquire the system information from a network device. [0003] In an LTE network, a network device periodically broadcasts a system message (SI message) to a terminal device, that is, the terminal device can receive the system message (SI message) broadcast from the network device. However, after the emergence of a new communication standard (such as NR), there is currently no corresponding method for how a terminal device obtains system information. Contents of the invention [0004] The present application provides a communication method, device and storage medium, which are used to obtain ...
