Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies when combining full duplex and half duplex communication devices, leading to delayed data communication processes and inconsistencies in frame transmission and reception sequences, particularly due to simultaneous response frames and the inability to transmit within regulated deadlines.
Innovation Solution
An electronic apparatus is designed with transmitter and receiver circuitry to manage frame durations, ensuring that the duration of secondary frames is equal to or greater than the difference between primary and response frame durations, and implementing specific timing protocols to maintain sequence consistency, even when mixed communication modes are used.

Engineering Contradiction Analysis
1Productivity
If full duplex communication is applied to improve communication speed, then effective communication speed is improved, but frame transmission and reception sequence consistency deteriorates when mixed with half duplex devices
Solution Approach 1:
The patent applies local quality by differentiating communication modes for different terminal types. The base station identifies whether each terminal is full duplex or half duplex capable, and applies appropriate communication protocols accordingly. This allows full duplex communication with full duplex terminals while maintaining half duplex protocols with half duplex terminals, thus improving overall communication speed while preserving sequence consistency for each terminal type.
Solution Approach 2:
The patent implements dynamic adaptation by allowing the base station to flexibly switch communication modes based on terminal capabilities. The system dynamically adjusts frame transmission timing, response frame handling, and communication protocols according to whether the terminal supports full duplex or only half duplex communication, enabling optimal performance for each device type while maintaining system-wide consistency.
2Productivity
If simultaneous transmission and reception is implemented to improve communication efficiency, then data transmission and reception can occur concurrently, but response frame collisions occur when multiple devices are involved
Solution Approach 1:
The patent segments the communication process by separating response frame transmission timing based on terminal type. Full duplex terminals are assigned different response timing protocols compared to half duplex terminals. This segmentation prevents response frame collisions by ensuring that terminals with different capabilities do not transmit response frames simultaneously, thereby maintaining communication efficiency while improving response frame transmission reliability.
3Stability of the object's composition
If frame duration is extended to accommodate response frames, then sequence consistency is maintained, but communication speed deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting frame duration and timing parameters dynamically based on terminal capabilities. For full duplex terminals, the system uses optimized frame durations that allow concurrent transmission and reception. For half duplex terminals, different timing parameters are applied to maintain sequence consistency. This parameter adaptation enables the system to maintain sequence consistency without unnecessarily extending frame durations, thus preserving communication speed.

AI summary
According to one embodiment, an electronic apparatus includes a transmitter circuitry and a receiver circuitry. The transmitter circuitry is configured to; transmit a first frame to a first terminal, and transmit a second frame to a second terminal when a first period elapsed after transmission of the first frame. The receiver circuitry is configured to receive a third frame including acknowledgement information of the first frame from the first terminal when the first period elapsed after transmission of the first frame. A duration of the second frame is set as equal to or greater than a difference between a duration of the third frame and a duration of the first frame.
