Problems solved by technology

[0005] In the prior art, PSS, SSS, PBCH, etc. are all sent separately, but the time domain interval between PSS, SSS, and PBCH is large, resulting in a large time delay. It can be seen that the transmission efficiency of the wireless communication system in the prior art is relatively low. Low

Abstract

The invention discloses a synchronization signal block (SS block) transmission method, a terminal and a base station. The method includes the following steps that: a base station generates an SS block, wherein the SS block contains a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel, or the SS block contains a primary synchronization signal, a secondary synchronization signal, a physical broadcast channel, and a transmission point synchronization signal; and the base station transmits the SS block to a terminal. With the SS block transmissionmethod provided by the embodiments of the invention adopted, delay can be decreased, and transmission efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method for sending a synchronization signal block SS block, a base station and a terminal. Background technique [0002] In an existing wireless communication system, such as an LTE system, before a base station communicates with a terminal device (User Equipment, UE), the UE first needs to access the base station. Currently, the UE generally implements access through random access. For example, in a Long Term Evolution (Long Term Evolution, LTE) system, when performing random access, the UE first performs downlink synchronization by detecting a primary synchronization signal (Primary Synchronization Signal, PSS) and a secondary synchronization signal (Secondary Synchronization Signal, SSS), and then The main system information such as the system frame number is obtained from the physical broadcast channel (Physical broadcast channel, PBCH) for acces...
