SIGNALING DETAILS FOR PRS STITCHING FOR POSITIONING IN A WIRELESS NETWORK

Abstract:

A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.
