Synchronizing signal block transmission information indication and determination method, base station and terminal

Abstract

The present invention provides a synchronizing signal block transmission information indication and determination method, a base station and a terminal. The problem is solved that there is no a related scheme about how to indicate the time-domain position of the actual transmission synchronizing signal block in the prior art. The method comprises the steps of: indicating transmission information of a target synchronizing signal block to a terminal through the remaining minimum system information (RMSI), wherein the target synchronizing signal block is a synchronizing signal block transmitted based on a base station. According to the embodiment of the invention, the transmission information of the target synchronizing signal block is indicated to the terminal through the RMSI to allow the terminal to determine the transmission information of the target synchronizing signal block through the RMSI so as to achieve indication and determination of the transmission information of the targetsynchronizing signal block, indicate the transmission information of the target synchronizing signal block through the RMSI to the terminal and reduce the signaling overheads with no need for messagebroadcast notification by employing other systems.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a method for indicating and determining transmission information of a synchronization signal block, a base station and a terminal. Background technique [0002] In the new air interface NR system, a synchronization signal block (Synchronization Signal block, referred to as SSblock) contains three parts: a symbol of the primary synchronization signal, a symbol of the secondary synchronization signal, two or more symbols of the physical broadcast channel ( Physical Broadcast Channel, referred to as PBCH). When the synchronization signal blocks are sent by means of beam scanning, the synchronization signal blocks in different directions are sent at different times. A number of sync blocks in one cycle constitute a burst set of SS blocks, and the transmission of the SS blocks in the burst set of SS blocks in each cycle is limited to a window of 5 ms. With...
