Abstract

The invention provides a synchronization signal transmission method and a terminal, and relates to the technical field of communication. The synchronization signal transmission method is applied to aterminal, and comprises the following steps: transmitting a sidelink synchronization signal block, wherein the sidelink synchronization signal block comprises a main sidelink synchronization signal PSSS and an auxiliary sidelink synchronization signal SSSS, and the PSSS and the SSSS are distributed in an orthogonal frequency division multiplexing OFDM symbol occupied by the sidelink synchronization signal block. According to the scheme, the PSSS and the SSSS are distributed in the OFDM symbol occupied by the sidelink synchronization signal block, so that the network communication process can be perfected, and the reliability of network communication is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a synchronization signal transmission method and a terminal. Background technique [0002] In the design of the New Radio (NR) system, the NR base station needs to send a synchronization signal block (Synchronization Signal Block, SSB, which can also be called SS / PBCH block, that is, synchronization signal / physical broadcast signal block) for terminal synchronization , system information acquisition, measurement evaluation, etc. An SSB consists of two parts: the New Air Interface Synchronization Signal (NR-SS) and the New Air Interface Physical Broadcast Channel (NR-PBCH). The NR-SS is divided into the New Air Interface Primary Synchronization Signal (NR-PSS) and the New Air Interface Secondary Synchronization Signal (NR-PSS). NR-SSS) in two parts. An SSB contains 4 symbols in total, and the time-domain composition order of these symbols in an SSB is PSS-PBCH-SSS...
