METHOD FOR PROVIDING BYPASS NETWORK PILOT IN OPEN RADIO CHANNEL

WIPO Patent Application WO/2021/018120

A1

Disclosed is a method for providing a bypass network pilot in an open radio channel, the method comprising: selecting a terminal station in an open radio channel as a reference, and sending a pilot signal, wherein the pilot signal sent occupies all or part of a frequency band of the open radio channel, said frequency band occupied by the pilot signal in the open radio channel is a pilot frequency band, and a ratio of a power of the pilot signal to a total power of the pilot frequency band ranges from 0.1‰ to 5%; and performing, when sending the pilot signal, spectrum spreading by means of a spreading code, and superimposing a noise-like low-power spectrum signal on a communication signal in the pilot frequency band, so as to cause an influence on a signal-receiving signal-to-noise ratio at a receiving end to be lower than an influence of a background thermal noise at the receiving end. The pilot signal provides pilot information, clock synchronization of carriers, and standard timing and indication information for network building and intercommunication of multiple types of terminal stations in the channel.
