Abstract

The present invention discloses a signal sending method and a terminal. The method includes: sending a synchronization signal block SSB in each time slot of a group of time slots; each time slot includes at least two SSBs, and each of the SSBs The sequence lengths of the primary synchronization signal PSS and the secondary synchronization signal SSS are different; the SSB is a combined block of the primary synchronization signal PSS, the secondary synchronization signal SSS and the physical broadcast channel PBCH. The scheme of the present invention can improve the detection success rate of the primary synchronization signal PSS, thereby reducing the bit error rate of SSB detection and increasing the coverage distance of the synchronization signal block.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a signal sending method and a terminal. Background technique [0002] In the 5G NR (NR Radio Access, new wireless access technology) V2X system, the PC5 port (Sidelink) is used for direct communication between terminals. Before the business data transmission, it is first necessary to establish synchronization between the two communicating terminals on the PC5 port (Sidelink). The method of establishing synchronization is that one terminal A sends synchronization and broadcast signals, and another terminal B receives the synchronization and broadcast signals sent by terminal A. Once terminal B receives and demodulates successfully, the two terminals can establish synchronization, which is the next step. Communication is ready. [0003] The synchronization signal of the NR UU port is carried by SSB (Synchronization Signal Block, synchronization signal block)....
