Radio frequency signal generation method and related apparatus

A baseband chip, comprising a processor and an interface, wherein

• the interface is configured to receive code instructions, and transmit the received code instructions to the processor;
• the processor is configured to run the received code instructions sent by the interface, to perform the following operations:
• determining an offset Δf of a center frequency for an RB signal relative to a zero frequency;
• and
• controlling a local oscillator to adjust a center frequency fib of a local oscillation signal generated by the local oscillator to flo+Δf, wherein the local oscillation signal whose center frequency is adjusted is used to perform up-conversion processing on the RB signal whose center frequency is zero.

A radio frequency signal generation method, comprising:

• determining, by a terminal device, an offset Δf of a center frequency for an RB signal relative to a zero frequency;
• adjusting, by the terminal device, a center frequency flo of a local oscillation signal to flo+Δf;
• and
• generating, by the terminal device, a radio frequency signal, wherein the radio frequency signal is obtained by performing, by the terminal device, up-conversion processing on the RB signal whose center frequency is zero by using the local oscillation signal whose center frequency is adjusted.
