Abstract

The invention discloses a transmission method, network equipment and user equipment of a synchronization signal block. The synchronization signal block includes NR-PSS, NR-SSS and NR-PBCH signals. The method includes: on the first time domain resource, through the second A frequency domain resource transmits NR-PBCH signals; and, on the second time domain resources, transmits NR-PSS and NR-SSS through the second frequency domain resources, and transmits physical signals and / or physical channels through the third frequency domain resources , wherein the first frequency domain resource includes a second frequency domain resource and a third frequency domain resource, and the physical signal and / or physical channel has the same beam characteristics as the synchronization signal block. The present invention transmits physical signals and / or physical channels through frequency domain resources other than NR-PSS, NR-SSS and NR-PBCH in the synchronization signal block, which can improve the resource utilization rate of the synchronization signal block, and further provide user equipment Access to the network and provide optimization strategies for network regulation and initial access.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method of a synchronous signal block, network equipment and user equipment. Background technique [0002] Before the user equipment communicates with the network equipment, it needs to perform a cell search to find the cell to which the user equipment is located, synchronize with the cell, and receive and decode the necessary information for communication and normal operation with the cell. Specifically, the user equipment obtains downlink synchronization and physical layer cell identity information of the cell by detecting a Primary Synchronized Signal (Primary Synchronized Signal, hereinafter referred to as: PSS) and a Secondary Synchronized Signal (hereinafter referred to as: SSS) at a specific location. (Cell ID), and then obtain necessary cell system information by receiving a physical broadcast channel (Physical Broadcast Channel, hereinafter r...
