Half-Duplex Message Scheduling With Protected Slots for Timely Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Half-duplex communication modes in scenarios requiring high timeliness and accuracy, such as power amplifier control in terminal/base station and antenna device communication, suffer from low transmission speed and inaccurate message transmission due to the use of a single transmission line.
Innovation Solution
A message transmission method that identifies message types as timely or temporary, allocating a dedicated transmission protect period for timely messages to ensure priority transmission, while temporary messages are sent outside these periods based on priority levels, maintaining communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If half-duplex communication mode is used to save transmission lines, then the quantity of transmission lines is reduced, but the message transmission speed and timeliness deteriorate
Solution Approach 1:
The transmission period is segmented into multiple sub-periods including uplink transmission sub-periods and downlink transmission sub-periods. Timely messages are allocated to specific sub-periods to ensure priority transmission, while temporary messages use remaining sub-periods. This segmentation allows efficient utilization of the single transmission line while guaranteeing timeliness for critical messages.
Solution Approach 2:
The system dynamically changes transmission parameters by assigning different priority levels to different message types. Timely messages (e.g., power amplifier control commands) are assigned high priority with dedicated transmission slots, while temporary messages are assigned lower priority. This parameter change in transmission scheduling resolves the contradiction by ensuring fast transmission for critical messages while maintaining half-duplex operation.
2Quantity of substance
If half-duplex communication mode is used to save transmission lines, then the quantity of transmission lines is reduced, but the message transmission timeliness deteriorates
Solution Approach 1:
The system performs preliminary action by pre-allocating transmission protect periods for timely messages before actual transmission occurs. These protected periods are reserved in advance in the transmission schedule, ensuring that when timely messages need to be sent, dedicated transmission slots are already available, thus guaranteeing timeliness without requiring additional transmission lines.
Solution Approach 2:
The system maintains continuity of useful action by ensuring that timely messages are continuously transmitted without interruption through the allocated protect periods. The transmission schedule is designed to provide continuous coverage for critical message types, eliminating gaps that would cause delays while still operating with a single transmission line.
3Quantity of substance
If single transmission line is used in half-duplex mode, then transmission line quantity is reduced, but message transmission accuracy deteriorates
Solution Approach 1:
The system applies local quality by providing different transmission quality levels to different message types. Timely messages receive high-quality transmission with dedicated protect periods and priority scheduling, while temporary messages use standard transmission quality. This localized quality differentiation ensures high accuracy for critical messages while maintaining efficient use of the single transmission line.

AI summary
The embodiments provide a message transmission method, a terminal, and a storage medium. In a message transmission method performed by a first terminal, a half-duplex communication mode is used between the first terminal and a second terminal, and the method includes: acquiring a message type of a message to be transmitted, wherein the message type comprises: a timely type and a temporary type; in response to determining that the message to be transmitted is a message of the timely type, allocating a corresponding transmission protect period for the message of the timely type, and preferentially transmitting the message of the timely type to the second terminal within the transmission protect period, so that the second terminal executes an operation corresponding to the message of the timely type, wherein the transmission protect period is used for transmitting the message of the timely type.
