Problems solved by technology

Among them, for the industrial sensing equipment scene, it may mean that there are a large number of sensing equipment in a certain space, such as pressure sensors, humidity sensors, thermometers, motion sensors ), accelerometers, actuators, etc. If these devices are connected to the network at the same time, they will bring greater access pressure to the network and may cause congestion
In addition, with the popularity of video surveillance and wearable devices, lightweight NR terminals are superimposed on ordinary terminals (such as enhanced mobile broadband (eMBB) service terminals (which can be called eMBB terminals) and / or low-latency, high-reliability communication (URLLC) terminal ((may be referred to as URLLC terminal))), which will further lead to an increase in access volume and bring greater pressure on terminal access

Embodiment Construction

[0144] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0145] In related technologies, the access process in the NR system includes: first, the terminal searches through the cell, that is, performs SSB search to obtain cell synchronization; then, after obtaining cell synchronization, the terminal obtains the CORESET# through the PBCH in the SSB 0, which is the initial BWP, and further obtain system information on CORESET#0, and perform corresponding random access operations on the corresponding initial uplink BWP (initial UL BWP); if only one frequency is sent in the cell SSB, all terminals access through the initial UL BWP. When there are a large number of terminals, access resource collision may occur, resulting in terminal access failure.

[0146] In the NR system, in order to improve the coverage performance, a Supplementary Uplink (SUL, Supplementary UpLink) carrier is introduced. As a supplementar...

Abstract

The invention discloses an information transmission method and device, network equipment, a terminal and a storage medium. The method comprises: a network device sending indication information to a terminal, the indication information indicating at least one of the following: at least one time domain and / or frequency domain resource, the at least one time domain and / or frequency domain resource being used for enabling the terminal to determine a time domain and / or frequency domain resource for receiving and / or sending information; whether the time domain and / or frequency domain resource corresponding to the indication information allows the terminal to access is determined; the indication information corresponds to a terminal type to which time domain and / or frequency domain resources are allowed to access; indicating at least one terminal processing capability supported by time domain and / or frequency domain resources corresponding to the indication information; the terminal type priorities to which time domain and / or frequency domain resources corresponding to the indication information are allowed to be accessed; the terminal type of the highest priority is allowed to be accessed by the time domain and / or frequency domain resource corresponding to the indication information.
