Wireless Positioning Signal Reporting with Phase-Continuous RSCPD

The patent segments the time points for carrier phase measurement into different groups based on phase continuity conditions. By dividing measurement opportunities into segments where phase continuity is maintained versus where it is disrupted, the system can selectively process measurements from continuous segments, thereby resolving the contradiction between obtaining multiple measurements for accuracy and maintaining phase continuity for reliability.

The patent applies preliminary action by determining phase continuity conditions before performing carrier phase measurements. The terminal identifies time points where phase continuity is maintained in advance, and only performs measurements at these pre-identified time points. This preliminary identification ensures that measurements are taken when phase continuity conditions are satisfied, resolving the contradiction between measurement frequency and phase continuity.

The patent maintains continuity of useful action by continuously monitoring phase continuity conditions and selectively performing measurements only when continuity is maintained. This continuous monitoring and selective measurement approach ensures that measurements are taken during periods of phase continuity, thereby improving measurement accuracy while avoiding the accumulation of initial phase errors that would occur with frequent measurements during discontinuous phases.

The patent implements feedback by using the determined RSCPD values to improve positioning accuracy. The measurement report containing RSCPD values is fed back to the network, which uses this information to refine positioning calculations. This feedback mechanism allows the system to achieve high positioning precision using only measurements taken during phase continuous periods, avoiding the need for frequent measurements that would introduce initial phase errors.
