Title:
METHODS AND APPARATUS FOR HIERARCHICAL COOPERATIVE POSITIONING
Document Type and Number:
WIPO Patent Application WO/2024/000424
Kind Code:
A1
Abstract:
Some embodiments of the present application provide for grouping of User Equipment (UEs) in clusters and/or tiers. The grouping may be based on a dynamically updated mean squared error-position/relative position map maintained at a transmission point. Additionally, grouping may be implemented in a hierarchical and cooperative manner, such that some UEs act, in a higher tier, as an Anchor UE to other UEs in lower tiers. Furthermore, the UEs may be understood to self-organize into clusters of UEs. A cluster of UEs may be represented by a single, representative UE to reduce signaling overhead between UEs in a given UE cluster and various Anchor UEs and/or transmission points. Moreover, cooperation between UEs in the same cluster may be based on sensing and on sharing, among the UEs, a relative position estimate and an position estimation MSE associated with the relative position estimate.
