Base Station Resource Selection via CORESET Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in 5G NR networks, small cell base stations face interference and resource collisions due to overlapping cell coverage with neighboring base stations, leading to inefficient resource usage and increased processing and signaling costs.
Innovation Solution
A method where a base station autonomously configures itself by extracting information from neighboring base stations with overlapping cell coverage, determining the locations of their control resource sets (CORESETs), and selecting non-overlapping resources to avoid interference, thereby optimizing its own resource allocation and reducing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base stations use overlapping cell coverage to expand network capacity, then network coverage and capacity are improved, but resource collisions and interference increase
Solution Approach 1:
The base station performs preliminary actions by extracting information from neighboring base stations and determining their CORESET locations before selecting its own resources. This advance planning allows the base station to identify and avoid potential resource collisions, thereby expanding network coverage without increasing interference.
Solution Approach 2:
The patent uses extracted information about neighboring base station CORESETs as an intermediary to mediate resource selection. By using this intermediate information, the base station can indirectly avoid resource collisions without direct coordination with neighboring base stations, enabling expanded coverage with reduced interference.
2Device complexity
If base stations autonomously select resources without coordination, then device complexity is reduced, but resource collision increases
Solution Approach 1:
The base station performs preliminary extraction of neighboring base station information and determination of CORESET locations before autonomous resource selection. This preliminary action provides the necessary information for reliable resource allocation while maintaining autonomous operation and low device complexity.
Solution Approach 2:
The base station uses the extracted information to serve itself in resource selection, making autonomous decisions based on neighboring base station configurations. This self-service approach reduces the need for complex coordination mechanisms while improving resource allocation reliability through informed decision-making.
3Measurement precision
If base stations extract and process information from neighboring base stations, then resource selection accuracy is improved, but processing overhead increases
Solution Approach 1:
The base station extracts only the necessary information from neighboring base stations - specifically, CORESET locations - rather than processing all possible parameters. This selective extraction improves resource selection accuracy while minimizing processing overhead by focusing only on the critical data needed for collision avoidance.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may extract information from a neighboring base station with cell coverage that overlaps cell coverage of the base station. The base station may determine, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring base station. The base station may select resources that do not overlap with the CORESETs used by the neighboring base station. The base station may transmit a communication using the selected resources. Numerous other aspects are described.
