Embodiment 1

[0073] In this embodiment, a method for sending a synchronization signal is provided, figure 1 is a flowchart of a method for sending a synchronization signal according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0074] Step S102, the base station determines one or more sets of system parameters, where each set of system parameters includes carrier frequency information and / or frame structure parameters;

[0075] Step S104, the base station constructs a synchronization signal of a predetermined structure according to system parameters;

[0076] Step S106, the base station sends the synchronization signal to the terminal;

[0077] Wherein, one or more sets of system parameters correspond to the same predetermined structure.

[0078] Through the above steps, the base station determines one or more sets of system parameters, wherein the system parameters are used to characterize the frequency information and...

Embodiment 2

[0110] In this embodiment, a synchronization signal sending device, a synchronization signal receiving device, and a synchronization signal transmission system are also provided. The device is used to implement the above embodiments and preferred implementation modes, and those that have already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0111] image 3 is a structural block diagram of a synchronization signal sending device according to an embodiment of the present invention, such as image 3 As shown, the device includes:

[0112] A determining module 30, configured to determine one or more sets of system parameters, where each set of system parameters i...

Embodiment 3

[0141] This embodiment is an optional embodiment according to the present application, and is used to describe the present invention in detail:

[0142] This embodiment provides a method and device for sending a synchronization signal, which are used to solve the problem of synchronization detection and access in an NR system.

[0143] Simply limiting the size of the system parameter set of the synchronization signal itself can achieve the requirement of reducing complexity. However, due to the difference in carrier frequency in the actual system, the requirement for different system parameters for the synchronization signal also exists, so the synchronization cannot be simply limited. Signal parameter selection.

[0144] One possible way is to decouple the design of the system parameters of the synchronization signal and the design of the structure of the synchronization signal as much as possible, allowing the system parameters of various synchronization signals in the NR sy...

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending and receiving synchronous signals, and a transmission system. Background technique [0002] In related technologies, the new generation of mobile communication system NR (new radio) will carry out system networking on a carrier frequency higher than that used by 2G, 3G, and 4G systems. Currently, the frequency bands widely recognized by the industry and recognized by international organizations are mainly 3GHz to 6GHz, 6GHz to 100GHz, this frequency band basically belongs to the centimeter wave band and the millimeter wave band. Studies have shown that the frequency is between 6G and 100GHz, especially at higher frequencies, the phase noise of radio frequency devices is very serious, and increasing the subcarrier width of the OFDMA system can resist the phase noise. The propagation characteristics of high-frequency bands are obviously different ...
