Sidelink Power Control via Distance-Based Pathloss

The patent implements dynamic power control by changing the transmission power parameter based on measured pathloss and distance values. The UE calculates adjusted power levels using formulas that incorporate these parameters, allowing the system to adapt power dynamically rather than using fixed levels, thereby reducing interference while managing complexity through mathematical relationships.

The system employs feedback mechanisms where the UE measures pathloss and distance parameters, then uses these measurements to adjust transmission power. The continuous measurement and adjustment loop creates a feedback system that automatically optimizes power levels to minimize interference with other transmissions in the wireless environment.

The patent resolves this contradiction by dynamically changing the transmission power parameter based on real-time pathloss and distance measurements. Instead of using fixed high power levels, the system calculates optimal power levels that are sufficient for reliable communication at the measured distance while minimizing excess power that would cause interference to other transmissions.

The system applies local quality by tailoring the transmission power specifically to the local communication conditions between the two UEs. Power levels are optimized for the specific distance and pathloss of this particular sidelink connection, rather than using uniform high power levels that would interfere with other transmissions in different locations or directions.
