Convergence Carrier Wave Signal Scheduling for Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in maximizing frequency spectrum utilization and minimizing complexity, especially with the need for high data transmission rates, as they often require independent working modes for each available carrier wave, leading to inefficient resource use and increased complexity.
Innovation Solution
The method involves using a convergence carrier wave that schedules synchronizing/broadcasting signals onto a single available transmission frequency segment and utilizes multiple available transmission frequency segments for communication, allowing the access network device and terminal to communicate on these segments without transmitting signals across all available segments, thereby improving spectrum utilization and reducing processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each available carrier wave adopts an independent working mode transmitting synchronizing and broadcasting signals separately, then signal transmission reliability is improved, but system implementation complexity increases and resources are wasted
Solution Approach 1:
The patent merges the transmission of synchronizing signals and broadcasting signals onto a single carrier wave instead of transmitting them separately on different carrier waves. This consolidation reduces the number of independent transmission channels, thereby decreasing system implementation complexity and resource consumption while maintaining signal transmission reliability through the unified carrier wave structure.
Solution Approach 2:
The single carrier wave in the patent serves multiple functions simultaneously: it transmits both synchronizing signals and broadcasting signals, and also supports data communication. This multi-functionality eliminates the need for separate dedicated carrier waves for different signal types, reducing overall system complexity while ensuring reliable transmission of all required signals.
2Speed
If multiple available carrier waves are used to increase data transmission bandwidth, then data transmission rate is improved, but frequency spectrum resource utilization ratio decreases
Solution Approach 1:
The patent employs dynamic resource allocation where the base station can flexibly assign different portions of the unified carrier wave spectrum to different users based on real-time communication needs. This dynamic scheduling allows efficient utilization of the available frequency spectrum, achieving high data transmission rates while maximizing spectrum resource utilization ratio through adaptive resource management.
Solution Approach 2:
The patent transitions from using multiple separate carrier waves (frequency domain approach) to using a single carrier wave with multiple transmission time slots (time domain approach). This dimensional change allows the system to achieve equivalent or higher data transmission rates while improving frequency spectrum resource utilization, as the time-division multiplexing approach allows more efficient packing of transmission opportunities within the available spectrum.
3Loss of energy
If a convergence carrier wave with multiple available transmission frequency segments is used, then frequency spectrum resource utilization ratio is improved, but signal transmission reliability may be compromised
Solution Approach 1:
The patent segments the unified carrier wave into multiple available transmission frequency segments that can be independently scheduled and allocated. This segmentation allows the system to flexibly assign specific frequency segments to different users or signal types, improving frequency spectrum utilization while maintaining reliability through selective activation of appropriate segments based on channel conditions and communication requirements.

AI summary
A method for communicating by using a convergence carrier wave, an access network device and a terminal are provided. The method includes: scheduling a synchronizing signal and a broadcasting signal of a system onto a first available transmission frequency segment of a convergence carrier wave to transmit the synchronizing and the broadcasting signal to a terminal, where the convergence carrier wave includes at least two available transmission frequency segments, and a bandwidth of the convergence carrier wave is smaller than or equal to the maximum working bandwidth of the system; determining to use the at least two available transmission frequency segments of the convergence carrier wave to communicate with the terminal; and communicating with the terminal on the at least two available transmission frequency segments of the convergence carrier wave.
