Base Station Beam Resource Allocation via Historical and Current Measurement Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, it is challenging for base stations to accurately indicate appropriate beams for wireless transmission between themselves and terminals, especially in scenarios where traditional measurement reports may not suffice.
Innovation Solution
The method involves the base station using comprehensive measurement reports from both historical and current data to determine a union set of resource sets, selecting resources with improved measurement values, and sending downlink or uplink indicator information to the terminal for optimal resource allocation, potentially utilizing spatial quasi-co-location relationships between signal ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station uses only current measurement reports to determine resources, then the resource allocation is simple and fast, but the accuracy and reliability of beam indication is insufficient
Solution Approach 1:
The base station performs preliminary determination of a first resource set based on historical measurement reports before determining the final resource set. This preliminary action incorporates past measurement data into the resource selection process, improving beam indication accuracy without requiring complete re-evaluation of all resources at each scheduling instance.
Solution Approach 2:
The patent merges historical measurement reports (first measurement reports) with current measurement reports (second measurement reports) to determine the final resource set. By combining information from both time periods, the system achieves more accurate beam indication while managing complexity through structured integration of multiple data sources.
2Reliability
If the base station determines resource set based on multiple measurement reports, then the resource allocation accuracy is improved, but the signaling overhead and processing time increase
Solution Approach 1:
The base station determines the first resource set based on historical measurement reports in advance, before the scheduling decision is made. This preliminary determination reduces the processing time required at the moment of resource allocation, as part of the analysis has already been completed using historical data.
Solution Approach 2:
The resource determination process is segmented into distinct stages: first, determining the first resource set based on historical measurement reports, then determining the second resource set based on current measurement reports, and finally determining the third resource set by combining both. This segmentation allows parallel processing and reduces overall determination time while maintaining reliability.
3Measurement precision
If the base station uses comprehensive measurement data from multiple reports, then the beam selection quality is improved, but the system complexity and computational load increase
Solution Approach 1:
The patent combines historical measurement reports and current measurement reports in a structured manner to determine the third resource set. This merging approach improves measurement precision by incorporating multiple data sources while managing complexity through a defined combination process rather than exhaustive analysis of all possible parameters.
Solution Approach 2:
The base station performs preliminary processing of historical measurement reports to establish the first resource set before combining with current measurements. This preliminary action reduces the computational load during the final resource determination by pre-processing and filtering historical data into a manageable first resource set.

AI summary
This application provides a communication method and an apparatus, to allocate a resource for wireless transmission between a base station and a terminal. The method includes: determining, by a base station based a first measurement report, a first resource set that can be used for wireless transmission between the base station and a terminal served by the base station; determining, by the base station based on a second measurement report, a second resource set that can be used for wireless transmission between the base station and the terminal, where the second measurement report is a measurement report currently reported by the terminal; determining, by the base station based on the first resource set and the second resource set, a third resource set that can be used for wireless transmission between the base station and the terminal, where the third resource set is some or all of resources of a union set of the first resource set and the second resource set; and sending, by the base station, first downlink indicator information to the terminal, where the first downlink indicator information indicates at least one resource in the third resource set.
