Sidelink OFDM Symbol CP Extension for Gap Alignment

The patent applies parameter changes by dynamically adjusting the OFDM symbol duration through cyclic prefix extension. The system modifies the time-domain parameters of the OFDM signal by extending the cyclic prefix length based on specific transmission conditions, thereby improving communication reliability without permanently increasing the entire transmission frame duration. This selective parameter adjustment allows the system to enhance reliability only when needed while maintaining efficient transmission timing.

The patent implements dynamics by making the OFDM symbol duration adjustable and adaptable to different transmission scenarios. The system dynamically selects whether to extend the cyclic prefix based on real-time transmission conditions, gap requirements, and service types. This dynamic adjustment mechanism enables efficient gap control between transmissions while avoiding the need for complex static configuration systems, as the extension is applied selectively rather than universally.

The patent applies local quality by extending the cyclic prefix only in specific local regions where needed for sidelink transmissions, rather than uniformly extending all OFDM symbols in the transmission frame. The system selectively applies the extension to particular symbols based on their function and position, ensuring compatibility with uplink symbols only where necessary. This localized approach minimizes the overall transmission overhead while maintaining the required compatibility in critical areas.
