AI Technical Summary
The limited frequency spectrum resources in new generation mobile communication systems, particularly in the 6 GHz to 100 GHz band, result in high phase noise and reduced coverage area due to increased propagation loss, necessitating adjustments in subcarrier spacing and frame structure parameters to maintain synchronization precision.
A method and apparatus for transmitting and receiving synchronization signals by determining the frequency band range and configuring subcarrier spacing and OFDM symbol information accordingly, using different subcarrier spacings (15 kHz, 30 kHz, 60 kHz, 120 kHz, or 240 kHz) and OFDM symbol configurations (1 to 16 symbols) based on the frequency band, and employing omnidirectional or directional antennas to enhance signal strength and coverage.
Improves synchronization precision between transmitting and receiving nodes by adapting subcarrier spacing and OFDM symbol information to the specific frequency band, effectively compensating for propagation losses and maintaining reliable communication in high-frequency bands.
