Abstract

The invention discloses a synchronization signal block transmission method, network equipment and user equipment. The synchronization signal block includes a new air interface primary synchronization signal NR-PSS, a new air interface auxiliary synchronization signal NR-SSS, and a new air interface physical broadcast channel NR-PBCH signal , the method includes: the network device sends NR-PSS through the first frequency domain resource, the second frequency domain resource sends NR-SSS, the third frequency domain resource sends the NR-PBCH signal, and the user equipment receives the NR-PSS through the first frequency domain resource. PSS, the second frequency domain resource receives NR‑SSS, and the third frequency domain resource receives NR‑PBCH signals. The positional relationship among the first frequency domain resource, the second frequency domain resource and the third frequency domain resource satisfies a preset condition. In the present invention, the positional relationship among the first frequency domain resource, the second frequency domain resource and the third frequency domain resource satisfies the preset condition, and the transmission of the synchronization signal block can be realized in the NR system, which is convenient for the user equipment to receive the synchronization signal block.

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 communicating with the core network, the terminal needs to perform a cell search to find the cell to which the terminal is located, synchronize with the cell, and receive and decode the necessary information for communication and normal operation with the cell. Specifically, the terminal obtains downlink synchronization and physical layer cell identity information ( Cell ID), and then obtain necessary cell system information by receiving a Physical Broadcast Channel (Physical Broadcast Channel, hereinafter referred to as: PBCH) signal. [0003] In the Long Term Evolution (hereinafter referred to as: LTE) system, in order to assist cell search, each downlink component carrier has two special signals PSS and SSS, and the PSS consists of a Z...
