Base Station Multicast Rate Policy for Terminal Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, multicast transmission efficiency is reduced when there are terminal stations with low transmission rates, as the transmission rate is set to the lowest rate among all connected stations, leading to suboptimal performance.
Innovation Solution
A method and system where a base station collects information on transmission rates and multicast usage frequencies from terminal stations, calculates policies to set unicast and multicast transmission rates, and switches connections based on these policies to optimize transmission efficiency, ensuring that terminal stations with higher multicast usage are connected to appropriate wireless communications units with suitable transmission rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multicast transmission rate is set to the lowest transmission rate of all terminal stations to ensure compatibility, then all terminal stations can receive multicast data, but transmission efficiency is greatly reduced
Solution Approach 1:
The patent segments terminal stations into different groups based on their transmission rate capabilities. By dividing the network into segments with different rate requirements, the system can apply appropriate transmission rates to each segment, avoiding the need to use the lowest rate for all stations and thereby improving overall transmission efficiency while maintaining compatibility within each segment.
Solution Approach 2:
The patent applies local quality by allowing different transmission rates in different parts of the network. Instead of using a uniform low rate across the entire network, the system configures appropriate transmission rates locally for each group of terminal stations based on their specific capabilities, thus optimizing transmission efficiency in each local context while ensuring compatibility within those local groups.
2Productivity
If multiple wireless communication units are used to connect terminal stations with different transmission rates, then transmission efficiency can be optimized, but device complexity increases
Solution Approach 1:
The patent makes wireless communication units universal by enabling them to adapt to multiple different transmission rate requirements. Instead of requiring separate dedicated units for each rate, a single wireless communication unit can be configured to work with terminal stations having different transmission rate capabilities, thus reducing the total number of units needed while maintaining optimized transmission efficiency.
Solution Approach 2:
The patent introduces dynamics by making the transmission rate configuration of wireless communication units adjustable and adaptable. The units can dynamically switch between different transmission rates based on which terminal stations are connected, allowing the system to optimize performance without requiring separate hardware for each rate scenario.

AI summary
A wireless communications method for connecting a base station with each of a plurality of terminal stations, the base station being equipped with a plurality of wireless communications units configured to be able to select a plurality of different transmission rates and connectable with one or more of the terminal stations, includes: a collection step of collecting information about a transmission rate and multicast transmission frequency from each of the terminal stations; a policy calculation step of calculating a setting policy for setting a unicast transmission rate and a multicast transmission rate for each of the wireless communications units and a switching policy for setting a condition for switching that one of the wireless communications units which is to be connected, for each of the terminal stations based on the collected information; and a setting step of setting those of the terminal stations which are to be connected, for each of the wireless communications units based on the calculated setting policy and switching policy.
