Direct Current Location Grouping for Lower Wireless Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face large signaling overheads due to terminals directly reporting direct current locations, including CC, BWP information, which is inefficient and resource-intensive.
Innovation Solution
Terminals report first information to network devices, which includes indication of power amplifier count, direct current location groups, capability to adjust locations, and direct current location information, allowing network devices to determine direct current locations without reporting every detail, thereby reducing signaling overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminals directly report all possible direct current locations including CC information, BWP information, and DC location, then the network device can accurately determine DC locations for interference management, but the signaling overhead becomes large
Solution Approach 1:
The patent segments the DC location reporting by grouping BWPs into BWP groups and dividing DC locations into multiple DC location groups. Instead of reporting all possible DC locations for all BWPs, the terminal reports DC locations only for the first BWP group, and the network device determines DC locations for other BWP groups based on the reported information and preset rules. This segmentation significantly reduces the quantity of DC location information that needs to be reported while maintaining accurate DC location determination capability.
Solution Approach 2:
The patent establishes preset mappings between BWP groups and DC location groups in advance, and defines default DC location determination rules before actual DC location reporting occurs. The network device is pre-configured with knowledge of which DC location group corresponds to which BWP group, and how to determine DC locations for non-first BWP groups based on reported DC locations from the first BWP group. This preliminary setup eliminates the need for repeated reporting of the same mapping information.
2Adaptability or versatility
If terminals report detailed information about each BWP and CC, then the network device can precisely manage interference across all carriers, but the complexity of information processing increases
Solution Approach 1:
The patent extracts only the essential DC location information from the first BWP group for reporting, rather than transmitting complete BWP and CC configuration details for all BWPs. The terminal identifies and reports only the DC locations associated with the first BWP group, while the network device uses pre-stored mapping relationships to infer the corresponding DC locations for other BWP groups. This extraction approach maintains comprehensive interference management capability while significantly reducing information processing complexity.
Solution Approach 2:
The reported DC location information from the first BWP group serves multiple purposes: it directly provides DC locations for the first BWP group, enables determination of DC locations for other BWP groups through preset mappings, and supports interference management across all carriers in the system. The network device uses this single set of reported information to achieve universal DC location determination for all BWP groups, reducing the need for separate reporting mechanisms for each BWP or CC.
