Irregular Positioning Signal Distribution for Joint Sensing

The patent applies asymmetry by transitioning from a regular periodic pattern to an irregular distribution pattern for positioning reference signals. Specifically, within each OFDM symbol, the frequency distance between consecutive resource elements containing positioning signals is made non-constant, creating an asymmetric and irregular pattern that eliminates sensing ghosts while maintaining systematic organization through grouped resource elements.

The patent applies segmentation by dividing resource elements into distinct groups, where each group contains a specific number of OFDM symbols and subcarriers. Within each group, a determined number of resource elements are allocated for positioning signals with irregular distribution. This segmented approach allows the system to manage complexity through modular organization while achieving irregular patterns that eliminate sensing ghosts.

The patent applies universality by designing a resource element organization structure that serves multiple functions simultaneously. The same irregularly distributed positioning reference signals are used for both positioning purposes (by user equipment) and sensing purposes (by network nodes), eliminating the need for separate dedicated sensing signals. This multi-functional approach reduces overall signalling overhead while maintaining accuracy for both joint sensing and positioning operations.
