Beam-Assisted Wireless Paging for Lower Latency Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in paging operations due to the lack of effective beam-related paging assistance information exchange between core networks, radio access networks, and user equipment, leading to suboptimal resource allocation and increased latency.
Innovation Solution
Implementing beam-related paging assistance information to facilitate efficient paging operations by enhancing communication between a centralized unit (CU) and a distributed unit (DU) of a base station, enabling more precise resource allocation and reduced latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional paging operations are used without beam-related assistance information, then the paging procedure can be implemented with simpler system architecture, but paging efficiency is reduced and latency increases
Solution Approach 1:
The patent applies preliminary action by having the user equipment provide beam-related assistance information to the core network before the actual paging operation occurs. This assistance information includes beam identifiers and directional data that are prepared in advance, enabling the network to quickly determine the appropriate beam for paging without performing extensive search or measurement operations during the paging process itself, thus improving paging efficiency while maintaining relatively simple system architecture
Solution Approach 2:
The patent introduces beam-related assistance information as an intermediary element that facilitates communication between the user equipment and the network during paging operations. This assistance information acts as a mediator that carries directional and beam-specific data, enabling the core network to efficiently identify and reach the target user equipment using appropriate beams, thereby resolving the contradiction between simplified architecture and improved paging efficiency
2Loss of time
If beam-related paging assistance information is exchanged between core network, radio access network, and user equipment, then resource allocation is optimized and latency is reduced, but the complexity of information exchange protocols increases
Solution Approach 1:
The patent extracts beam-related assistance information from the complex paging protocol and separates it into a distinct data element that can be independently handled. By extracting this specific information (beam identifiers, directional data) from the overall paging message structure, the system can process and exchange only the necessary beam-related data between core network, radio access network, and user equipment, reducing the complexity of information exchange while achieving optimized resource allocation and reduced latency
Solution Approach 2:
The patent segments the paging information into distinct components, with beam-related assistance information being one separate segment. This segmentation allows the beam-specific data to be processed, stored, and exchanged independently from other paging information, enabling more efficient resource allocation and reduced paging latency without requiring the entire paging protocol to become more complex

AI summary
Beam-related paging assistance information can be exchanged between a core network, radio access networks, and user equipment. Beam-related paging assistance information can enable more efficient paging operations at a base station. A centralized unit (CU) of a base station can exchange beam-related paging assistance information with a distributed unit (DU) of the base station to facilitate paging operations using the beam-related paging assistance information.
