Paging-Based Sensing Capability Inquiry in Wireless UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently querying User Equipment (UE) about their sensing capabilities and reacting to sensing tasks, especially when UEs are in RRC inactive or idle states.
Innovation Solution
The system implements a method where UEs receive a paging radio network temporary identifier (P-RNTI) and information about paging occasions associated with it. Based on this, UEs determine their sensing suitability and transmit a request to transition to the RRC connected state for sensing tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If UEs are kept in RRC inactive or idle states to save energy, then energy consumption is reduced, but the ability to quickly query sensing capabilities and respond to sensing tasks is worsened
Solution Approach 1:
The network pre-configures UEs with sensing capability indicators and paging occasion information while they are in RRC inactive or idle states. This preliminary action allows UEs to be quickly activated for sensing tasks without requiring full RRC connection establishment, thus maintaining energy savings while improving response capability.
2Ease of operation
If UEs transition to RRC connected state for sensing tasks, then sensing capability querying is improved, but energy consumption and signaling overhead increase
Solution Approach 1:
The patent extracts the sensing capability inquiry and response mechanism from the full RRC connection establishment process. By using dedicated paging messages and pre-configured parameters, the system separates the essential sensing capability exchange from the complete connection setup, reducing energy consumption and signaling overhead while maintaining operational ease.
3Adaptability or versatility
If the system implements paging-based sensing capability inquiry, then UE capability utilization in inactive/idle states is improved, but system complexity increases
Solution Approach 1:
The patent makes the paging mechanism universal by enabling it to serve both traditional wake-up functions and new sensing capability inquiry functions. The same paging infrastructure and message structures are reused for multiple purposes, avoiding the need for separate dedicated signaling mechanisms and thus limiting the increase in system complexity.

AI summary
Various aspects of the present disclosure relate to techniques for radio-based sensing. An apparatus is configured to receive a paging radio network temporary identifier (P-RNTI) for receiving a paging message associated with sensing, receive information associated with paging occasions (POs) to be monitored that are associated with the P-RNTI, receive a paging message based on the received P-RNTI and the information associated with the POs, determine sensing suitability of the UE based on the received paging message, and transmit a request to transfer to radio resource control (RRC) connected state based on the determined sensing suitability.
