[0074] figure 1 It is a flowchart of a channel recording method based on 5G operating signals provided by an embodiment of the present invention. Such as figure 1 As shown, the method is applied to a user terminal and at least includes the following steps:
[0075] S101. Search and obtain a synchronization signal block (SSB) from the intercepted 5G operation signal;
[0076] S102. Obtain a primary synchronization signal and a secondary synchronization signal from the SSB;
[0077] S103. Demodulate the PSS and SSS to obtain a physical cell identity (PCI);
[0078] S104. Determine the frequency domain position of the demodulation reference signal of the PBCH according to the physical cell identity (PCI); blindly decode the DM-RS in the PBCH according to the frequency domain position of the DM-RS, and obtain the position index of the synchronization signal block and half-frame information, In order to achieve half-frame synchronization;
[0079] S105. Decode the PBCH to ob...
