Abstract

An initial cell detection method and device, a storage medium and a terminal, the method comprising: receiving data based on a maximum SCS mode associated with SSB, the data comprising information forinitial cell search; when the SSB is associated with a plurality of SCS modes, for each SCS mode, performing initial cell detection on the data in the SCS mode; and determining the initial cell according to the respective initial cell detection results of the plurality of SCS modes. Through the scheme provided by the invention, the initial cell detection and the SCS detection can be simultaneously completed through one-time data collection in the NR system, the network searching time is greatly optimized, and the efficiency is improved.

Description

technical field

[0001] The present invention relates to the field of communication technologies, and in particular to an initial cell detection method and device, a storage medium, and a terminal. Background technique

[0002] In a mobile communication system, after the terminal is turned on, it needs to search for a suitable cell as soon as possible, so as to be synchronized with the cell in time and frequency, and then read the broadcast message of the cell. Wherein, the process from when the terminal is turned on and searches to camping on a suitable cell is the initial cell search process, which may also be referred to as the initial cell search process.

[0003] Currently, the mainstream design solution for initial cell search is to use a primary synchronization signal (Primary Synchronization Signal, PSS for short) and a secondary synchronization signal (Secondary Synchronization Signal, SSS for short).

[0004] In the New Radio (NR, NR for short, also called New Air ...
