AI Technical Summary

Technical Problem

Existing wireless networks face challenges in efficiently transporting large volumes of sensing measurements made by user equipment (UEs) without causing delays or performance degradation, as conventional signaling radio bearers (SRBs) are inadequate for handling the significant data volume, while data radio bearers (DRBs) lack visibility to radio access network (RAN) nodes.

Method used

Implementing a new radio bearer, such as a sensing radio bearer (SeRB), to transport sensing measurements, which includes configuring it with specific protocol layers and priorities to ensure efficient data transmission and visibility, while allowing for both raw and processed measurement results to be sent via sensing processing protocols (SPP) to a sensing function in the core network.

Benefits of technology

This approach avoids delays and performance degradation associated with SRBs and lack of visibility in DRBs, enabling flexible network configurations and efficient transport of sensing-related information, facilitating different placements of sensing processing functions within the network.

Abstract

Embodiments include methods for a user equipment (UE) configured for sensing and communication in a radio access network (RAN). Such methods include receiving a request to perform sensing measurements associated with one or more sensing services and performing sensing measurements in accordance with the request. Such methods include sending a sensing measurement report that includes results of the sensing measurements. The sensing measurement report is sent via one or more of the following: a sensing processing protocol (SPP) between the UE and a sensing function in a core network coupled to the RAN; and a sensing radio bearer (SeRB) that is terminated at the sensing function or at a RAN node serving the UE. Other embodiments include complementary methods for a RAN node, as well as UEs and RAN nodes configured to perform such methods.
