Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device interfaces often experience reduced data communication efficiency due to half-duplex connections, leading to shorter full-duplex communication durations and reduced data transmission amounts.
Innovation Solution
An electronic device that detects the signal transmission policy of a host by receiving initial and completion signals, and transmits a detection signal to determine when to send a completion signal, thereby extending full-duplex communication time and improving data transmission efficiency by varying the completion signal transmission based on the detected policy.

If conventional half-duplex connection is used for data communication, then device complexity is reduced, but data transmission efficiency and full-duplex communication duration are reduced
Solution Approach 1:
The electronic device performs preliminary detection of the host's signal transmission policy during the connection establishment phase, before actual data transmission begins. By receiving an initial command signal and its corresponding completion signal, the device determines whether the host uses first policy (sends completion signal after N data frames) or second policy (sends completion signal after receiving completion signal), and configures the appropriate response strategy in advance. This preliminary action enables full-duplex communication during data transmission without requiring complex real-time decision-making.
Solution Approach 2:
The electronic device dynamically adjusts its completion signal transmission behavior based on the detected host policy. When the host uses the first policy, the device transmits completion signals after sending a predetermined number of data frames; when the host uses the second policy, the device transmits completion signals after receiving completion signals from the host. This dynamic adaptation allows the device to maintain optimal full-duplex communication duration and data transmission efficiency while interfacing with different host types.

If completion signal is transmitted frequently to maintain communication synchronization, then communication reliability is improved, but full-duplex communication duration is reduced
Solution Approach 1:
The electronic device implements a feedback mechanism by detecting the host's signal transmission policy through initial command and completion signal exchange. Based on this feedback, the device determines the appropriate completion signal transmission timing: either after sending a predetermined number of data frames (for first policy hosts) or after receiving completion signals from the host (for second policy hosts). This feedback-driven approach ensures communication synchronization is maintained reliably while maximizing full-duplex communication duration by avoiding unnecessary completion signal transmissions.

AI summary
An electronic device configured to communicate with a host includes: a detecting logic configured to receive an initial command signal and a first completion signal according to the initial command signal after a connection of the host to the electronic device is established, and transmit a detection signal based on a signal transmission policy of the host that has been detected based on the initial command signal and the first completion signal; and a transmitting logic configured to transmit a second completion signal to the host based on the detection signal, wherein the signal transmission policy is different depending on whether the first completion signal is received in response to the second completion signal.
