Reference Signal Timing Alignment Between Base Stations

The patent introduces a reference signal as an intermediary element that mediates between transmission timing errors and timing measurement. By measuring the timing difference between received reference signals from different base stations, the system can identify and compensate for transmission timing errors without requiring complex hardware modifications. The reference signal acts as a common reference that enables timing error detection and correction through software processing rather than hardware perfection.

The patent implements a feedback mechanism where timing difference information is measured, reported, and used to adjust transmission timings. The base station receives timing difference measurements from user equipment and uses this feedback to compensate for its transmission timing errors. This closed-loop feedback system enables continuous timing error correction without requiring perfectly precise hardware, resolving the contradiction between timing accuracy and hardware complexity.

The patent enables user equipment to autonomously measure and report timing differences between base stations without requiring complex centralized coordination. The UE self-performs the timing measurement using reference signals, calculates the timing difference, and reports it to the appropriate base station. This self-service approach simplifies the overall system complexity by distributing the timing measurement function to individual UEs rather than requiring a complex centralized synchronization protocol.

The patent measures and compensates for timing differences between base stations rather than attempting to perfectly synchronize all transmission timings. By focusing on measuring and correcting the relative timing differences between base stations using reference signals, the system achieves practical synchronization accuracy without implementing excessively complex protocols that would attempt to eliminate all timing variations. This partial action approach resolves the contradiction by achieving sufficient synchronization without excessive system complexity.
