Abstract

The invention relates to a signal sending and receiving method and a device thereof, the signal sending method comprises the following steps: generating synchronization signals, the synchronization signals comprising a first synchronization signal and a second synchronization signal; and sending the synchronization signal, wherein the first synchronization signal and the second synchronization signal are overlapped in the time domain, and in the overlapped time domain resource of the first synchronization signal and the second synchronization signal, the frequency domain resource correspondingto the first synchronization signal and the frequency domain resource corresponding to the second synchronization signal have an intersection. According to the embodiment of the invention, the two synchronization signals are not completely independent, but are partially overlapped on the frequency domain, so that the frequency domain resources occupied by the synchronization signals can be reduced, the frequency domain resources are saved for other data transmission processes, the two synchronization signals can also share one part of frequency domain resources, and the utilization rate of the resources is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal sending and receiving method and device. Background technique [0002] Generally speaking, when a terminal device accesses a wireless communication system, such as a long term evolution (long termevolution, LTE) system or a new radio (new radio, NR) system, it needs to be synchronized with network devices under the wireless communication system first, That is, first obtain the synchronization information of the network device by detecting the synchronization channel. The synchronization information can include time synchronization information and / or frequency synchronization information, and it is also possible to obtain the information of the cell under the jurisdiction of the network device, so as to ensure subsequent communication with the network device. Normal data communication. [0003] Currently, synchronization channels are designed separat...
