Radio Frame Merging for Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiocommunication systems with multiple devices, the repeated transmission of the same frame to multiple requesting devices leads to significant mobilization of radio resources and energy consumption, particularly disadvantageous for devices with autonomous energy supply, such as mobile devices.
Innovation Solution
A method where a single frame is transmitted in a predetermined time slot to multiple devices, with the first device initiating the request and receiving the frame, allowing other devices to use it if their requests are detected during this slot, reducing the number of frames sent and thus minimizing resource mobilization and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same frame is transmitted multiple times to multiple requesting devices, then each device receives the frame reliably, but radio resources are significantly mobilized and energy consumption increases
Solution Approach 1:
Multiple frame transmissions that would otherwise be separate and redundant are merged into a single transmission. The first requesting device receives the frame in response to its request, and subsequent requesting devices within the same time slot also receive this same frame, eliminating the need for repeated transmissions and significantly reducing energy consumption.
Solution Approach 2:
A single frame transmission serves multiple functions by being received by multiple requesting devices simultaneously. The frame is not dedicated to a single device but is universally useful to all devices that transmitted requests within the predetermined time slot, making the transmission resource-efficient for the entire group.
2Reliability
If the same frame is transmitted multiple times to multiple requesting devices, then each device receives the frame reliably, but radio resources are significantly mobilized
Solution Approach 1:
Multiple frame transmissions are merged into one. Instead of allocating separate radio resources for each device's frame reception, a single radio resource allocation suffices to serve all requesting devices within the time slot, reducing the total quantity of radio resources mobilized.
Solution Approach 2:
The transmitted frame has universal applicability to multiple devices, allowing one frame to fulfill the communication needs of all requesting devices simultaneously. This universality reduces the quantity of radio resources required compared to device-specific transmissions.
3Productivity
If the frame transmission time slot is extended to accommodate multiple requests, then all requesting devices can use the same frame, but channel stationarity may be compromised leading to operational inaccuracies
Solution Approach 1:
The time slot is extended partially—just enough to accommodate multiple request transmissions and a single frame transmission—rather than excessively. This partial extension achieves the goal of serving multiple devices while minimizing the duration over which channel conditions may change, thereby maintaining measurement precision.
Solution Approach 2:
The duration of the time slot is optimized as a parameter to balance two competing requirements: it must be long enough to accommodate multiple requests and enable resource sharing, but not so long that channel non-stationarity degrades measurement accuracy. This parameter optimization resolves the contradiction between productivity and precision.

AI summary
The invention relates to a method of implementing operations involving the processing a radio-communication frame (CMF) in a system comprising at least three radio transmitter/receiver devices (1-5), consisting in transmitting the frame in response to a first request signal (REQ1) transmitted by a device belonging to the system (1). According to the invention, the frame is processed in the device (1) that transmitted the first request signal (REQ1) as well as in other devices belonging to the system (1, 3-5) which transmitted respective request signals (REQ2-REQ4) within a pre-determined time period.
