Problems solved by technology

[0006] Embodiments of the present invention provide a signal transmission method and network equipment to solve the problem of high-frequency SSB transmission. If the transmission direction of multiple SSBs is intercepted before transmission, the base station has no way to respond to the unseen SSB transmission. The transmitted SSB occupies the channel, which may lead to the problem that the channel is occupied by other RATs or transmission nodes

Abstract

The invention provides a signal transmission method and network equipment, and relates to the technical field of communication. The signal transmission method is applied to network equipment, and includes: performing channel detection on the transmission direction of the SSB in an unlicensed frequency band before transmission of a synchronization signal block SSB; and transmitting the SSB when the detected channel is idle. In the above solution, by performing channel detection on the transmission direction of the SSB in the unlicensed frequency band before the transmission of an SSB, when the channel is detected to be idle, the SSB is transmitted; in this way, the transmission of the SSB can be realized before the transmission of the SSB. The interception of SSB can improve the reliability of SSB transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a signal transmission method and network equipment. Background technique [0002] In the future communication system, the unlicensed frequency band (unlicensed band) can be used as a supplement to the licensed frequency band (licensed band) to help operators expand the service capacity. In order to be consistent with New Radio (NR) deployment and maximize NR-based unlicensed access as much as possible, the unlicensed frequency band can work in the 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80MHz or 100MHz) of the unlicensed frequency band can reduce the implementation complexity of the base station and user equipment (User Equipment, UE, also called terminal). Since the unlicensed frequency band is shared by multiple radio access technologies (Radio Access Technology, RAT), such as WiFi, radar, Long Term Evolution Licensed-Assisted Access (LTE-LAA), etc.,...
