Random Access Resource Reporting for Beam-Aware Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks are limited by the insufficient reporting of random access (RA) information, which hinders the network's ability to adequately assess the resources used during the RA procedure.
Innovation Solution
Wireless communication devices store multiple sets of RA resource information and transmit this information to the network in response to an indicator, including detailed parameters such as RA resources, preamble group indication, time-related information, and beam-related data, enabling comprehensive reporting of RA procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the network requests detailed RA information from wireless communication devices, then the network's understanding of RA resource usage is enhanced, but the signaling overhead and communication complexity increase
Solution Approach 1:
The patent extracts only the necessary RA information elements (such as preamble ID, PRACH resource index, SSB index) that are relevant for network assessment and excludes unnecessary detailed data. This selective extraction approach reduces signaling overhead while maintaining the network's ability to adequately assess RA resource usage.
Solution Approach 2:
The patent implements partial reporting by including only a subset of RA procedure details based on network needs and configured parameters. The reporting can be adjusted to include varying levels of detail (e.g., only failure cases, or all cases with optional detailed parameters), allowing the network to balance information completeness against signaling overhead.
2Measurement precision
If multiple sets of RA resource information are stored and reported, then the network's assessment capability is improved, but the memory requirements and processing burden on the device increase
Solution Approach 1:
The patent segments the RA information reporting into different categories (e.g., successful RA, failed RA, different beam failures) and allows selective reporting based on configuration. The device can store multiple sets of RA resources but only processes and reports relevant segments based on network requests and event triggers, reducing overall processing burden.
Solution Approach 2:
The patent introduces configurable parameters (such as reporting thresholds, event triggers, and information element selection) that allow dynamic adjustment of what RA information is stored, processed, and reported. This enables the device to adapt its processing burden to network requirements without permanently maintaining all possible information sets.
3Adaptability or versatility
If comprehensive RA information including beam-related data is reported, then the network's beam management capability is enhanced, but the message size and transmission overhead increase
Solution Approach 1:
The patent extracts only the essential beam-related parameters (such as SSB index, beam failure instance, and associated RA resources) needed for beam management decisions, omitting redundant beam measurement details. This selective extraction provides sufficient beam management capability while keeping message sizes manageable.
Solution Approach 2:
The patent designs the RA information reporting structure to serve multiple functions simultaneously: it provides beam management information, RA resource assessment data, and failure analysis details within a unified reporting framework. This multi-functionality reduces the need for separate dedicated beam reporting messages, thereby reducing overall message size.

AI summary
Systems and methods for storing and transmitting random access (RA) information related to one or more RA procedures is discussed herein. In one embodiment, the systems and methods are configured to storing, by a wireless communication device, RA information of multiple sets of RA resource of a completed RA procedure. The method further includes receiving, by the wireless communication device from a wireless communication node, an indicator via a radio resource control (RRC) message. The method also includes transmitting, by the wireless communication device to the wireless communication node, responsive to the indicator, the RA information of the multiple sets of RA resource of the completed RA procedure.
