Base Station Rate Policy for Mixed Terminal Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems where multiple terminal stations with different transmission rates coexist, the efficiency of data transmission is reduced due to the need for control signals to be transmitted at a stable basic rate, affecting overall system efficiency.
Innovation Solution
A method and system where a base station collects information on the transmission rates of each terminal station, calculates and sets a basic rate and switching policy for wireless communications units to optimize connections, allowing multiple permitted transmission rates and adjusting propagation delays based on antenna directivity or selection, enabling efficient communication with terminals of varying rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control signals are transmitted at a low basic rate to ensure stable reception by all terminal stations, then reliability of control signal transmission is improved, but transmission efficiency of the system deteriorates
Solution Approach 1:
The patent segments terminal stations into different groups based on their transmission rate capabilities. The base station divides terminal stations into a first group (capable of high transmission rates) and a second group (requiring low basic rates for control signals). This segmentation allows the base station to transmit control signals at low rates to ensure reliability for all terminals while enabling high-rate data transmission to the first group, thus resolving the contradiction between reliability and transmission efficiency.
2Adaptability or versatility
If the base station uses multiple wireless communications units with different permitted transmission rates, then adaptability to various terminal stations is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic configuration where the base station can switch between different wireless communications units based on the transmission rate requirements of terminal stations. The base station dynamically determines which communication unit to use for each terminal station, allowing flexible adaptation to varying rate requirements without requiring all units to operate simultaneously, thus managing complexity while maintaining adaptability.
Solution Approach 2:
The patent applies local quality by assigning different permitted transmission rates to different wireless communications units based on the specific requirements of connected terminal stations. Each communication unit is configured with appropriate rate settings localized to the needs of its associated terminals, allowing optimized performance for each group while maintaining overall system manageability.
