Wireless Station Tournament Protocol Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless telecommunication networks using the tournament method suffer from poor bandwidth utilization and prolonged contention resolution protocol execution times, leading to significant bandwidth loss and inefficient data transmission.
Innovation Solution
A transmission control method that allows information signals related to the tournament to be transmitted during data frame transmission, eliminating the need for a silent period and reducing the duration of the tournament, by using alternative frequency bands, embedding signals in data frames, or transmitting after a determined period of silence, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tournament method is used to control transmissions and limit collision rates, then collision rate is reduced, but bandwidth utilization deteriorates due to prolonged contention resolution protocol execution time
Solution Approach 1:
The patent merges the tournament contention resolution protocol with data frame transmission by embedding tournament information signals within the data frames themselves. This allows the tournament protocol and data transmission to occur simultaneously rather than sequentially, resolving the contradiction between reducing collisions and maintaining bandwidth utilization.
Solution Approach 2:
The patent enables continuous useful action by allowing tournament information signals to be transmitted during the entire duration of data frame transmission. This eliminates idle periods where the channel is reserved for tournament protocols alone, keeping the transmission medium continuously productive for both contention resolution and data transfer.
2Reliability
If tournament information signals are transmitted separately before data frames, then collision resolution is achieved, but transmission time increases due to the need for silent periods
Solution Approach 1:
The patent combines tournament information signal transmission with data frame transmission into a single simultaneous operation. By embedding the tournament protocol within the data transmission timeframe, the system eliminates the need for separate silent periods before data frames, thereby reducing total transmission time while maintaining reliable contention resolution.
Solution Approach 2:
The patent performs preliminary action by embedding tournament information signals within the data frame structure itself, so that the contention resolution process is initiated and completed concurrently with data transmission rather than requiring a separate preliminary time slot.
3Reliability
If dedicated time intervals are allocated for tournament protocols, then contention resolution is ensured, but bandwidth efficiency deteriorates due to idle transmission periods
Solution Approach 1:
The patent merges two previously separate functions—contention resolution and data transmission—into a single integrated process. By transmitting tournament information signals within the data frame transmission interval, the system eliminates dedicated idle time intervals for tournaments, thereby improving bandwidth efficiency while ensuring reliable contention resolution through the embedded protocol.
Solution Approach 2:
The patent applies multi-functionality by making the data transmission interval serve dual purposes: both conveying data and carrying tournament contention resolution information. This universal use of the transmission medium eliminates wasted bandwidth while maintaining the integrity of the contention resolution process.

AI summary
The invention relates to a transmission control method implemented by a station having at least one data frame to be transmitted via a wireless telecommunication network. In one aspect, the method comprises, at each selection round from a maximum number of selection rounds: a step of obtaining a value representative of either an authorization to transmit the frame, or of a prohibition to transmit the frame; and, when the value is representative of an authorization for transmission, transmitting an information signal in the network so as to indicate, to the other stations, that the station has obtained a value representative of an authorization for transmission. The transmission of the information signal is at least partially carried out during the transmission of a data frame in the network.
