AI Technical Summary
Technical Problem
The terminal equipment cannot determine the Doppler frequency offset and the crystal oscillator frequency offset, resulting in poor frequency offset compensation.
Method used
The network device sends a synchronization signal block (SSB) and a pilot signal to the terminal device. The SSB contains indication information to indicate the position of the pilot signal. The terminal device determines the Doppler frequency offset and the crystal oscillator frequency offset based on the SSB and the pilot signal.
Benefits of technology
This enables terminal devices to accurately determine Doppler frequency offset and crystal oscillator frequency offset, thereby performing effective frequency offset compensation and improving the accuracy of signal reception.

Abstract
Embodiments of the present application provide a communication method, device, electronic equipment, storage medium and program product. The method comprises: a network device sends a synchronization signal block (SSB) and a pilot signal to a terminal device, the SSB is used to indicate the position of the pilot signal. The terminal device receives the pilot signal according to the SSB; and determines a Doppler frequency offset and a crystal frequency offset according to the SSB and the pilot signal. Through the above method, the terminal device can determine the Doppler frequency offset and the crystal frequency offset according to the pilot signal, thereby achieving the purpose of determining the Doppler frequency offset and the crystal frequency offset.
