Solution Overview
Problem
Current wireless communication technologies face inefficiencies in configuring and utilizing bandwidth parts (BWP) for effective communication, particularly in managing channel occupancy and congestion, leading to suboptimal resource allocation and processing efficiency.
Innovation Solution
The implementation of an electronic device with processing circuitry that receives and transmits indication information on bandwidth part sets, detects future occupancy durations, and notifies base stations, enabling efficient communication by optimizing BWP configuration and reducing unnecessary channel detection through enhanced preamble detection and channel occupancy indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bandwidth parts are configured and managed for carriers greater than 20 MHz, then communication flexibility and resource allocation capability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the carrier bandwidth into multiple bandwidth parts (BWPs), each representing a continuous set of resource blocks. This segmentation allows independent configuration and management of different BWP sets, enabling flexible resource allocation while reducing the complexity of managing the entire carrier at once. Each BWP can be activated or deactivated independently through indication information.
Solution Approach 2:
The patent implements dynamic BWP management where the base station can activate different BWPs or BWP sets based on current communication needs. The indication information mechanism allows real-time switching between BWPs without reconfiguring the entire carrier, providing adaptability while maintaining manageable system complexity through on-demand activation.
2Reliability
If channel occupancy detection is performed frequently to manage bandwidth parts, then channel access reliability is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent performs Clear Channel Assessment (CCA) before activating a BWP for transmission. This preliminary channel occupancy detection ensures that the device checks channel availability in advance, improving reliability by preventing transmissions on occupied channels while maintaining efficient time usage through targeted pre-checks rather than continuous monitoring.
3Productivity
If bandwidth part configuration is optimized for efficient communication, then resource allocation efficiency is improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent creates a universal BWP management framework where indication information serves multiple functions: activating BWPs, switching between BWPs, and managing BWP sets. This multi-functional approach improves resource allocation efficiency across different scenarios while reducing processing complexity by using a unified mechanism rather than separate procedures for each function.
