AI Technical Summary

Technical Problem

In the new wireless (NR), the synchronization grid configuration of the environmental Internet of Things (A-IoT) terminals is difficult to match its narrow bandwidth characteristics, resulting in synchronization complexity and failure problems.

Method used

By determining the synchronization grid associated with the first type of terminal, the access network device can send the corresponding synchronization signal to ensure that the frequency interval of the synchronization grid is less than or equal to the threshold value, and avoiding the synchronization grid being too sparse.

Benefits of technology

It effectively solves the problems of complex and failure of A-IoT terminal synchronization, reduces the complexity of searching for synchronization signals, and improves the transmission performance of synchronization signals.

Abstract

A communication method and apparatus. Synchronization rasters of a first-type terminal are associated with a first frequency interval, for example, the frequency interval between adjacent synchronization rasters in the first-type terminal is referred to as the first frequency interval, and the first frequency interval is less than a first threshold, so as to prevent synchronization rasters configured for the first-type terminal from being too sparse, thereby solving the problems of complex synchronization, synchronization failure and the like caused by the first-type terminal continuing to use too sparse synchronization rasters of traditional terminals.
