Uplink Time-Unit Selection for Reliable Full-Duplex Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In full-duplex communication, terminals face challenges in determining the appropriate time units for uplink information transmission when multiple types of time units are involved, leading to inconsistent understanding with the base station and reduced reliability.
Innovation Solution
The terminal and base station determine a first time unit for uplink transmission by considering the types of time units, including those with and without uplink sub-bands, using predefined protocols or indication information, ensuring consistent resource understanding.

Engineering Contradiction Analysis
1Quantity of substance
If the terminal uses multiple time units for uplink information transmission, then the transmission capacity is improved, but the reliability of communication is deteriorated due to inconsistent understanding between terminal and base station
Solution Approach 1:
The base station provides indication information to the terminal to specify which time units are selected for uplink transmission. This feedback mechanism ensures that the terminal's selection of multiple time units aligns with the base station's expectations, resolving the inconsistency that would otherwise reduce communication reliability while maintaining the improved transmission capacity.
Solution Approach 2:
The base station pre-configures indication information that defines the rules for selecting time units before the actual transmission occurs. This preliminary action establishes a common understanding between the terminal and base station about which time units will be used, preventing misinterpretation and ensuring reliable communication while allowing the terminal to utilize multiple time units for enhanced capacity.
2Ease of operation
If the terminal determines time units autonomously, then the operation flexibility is improved, but the consistency with base station understanding is deteriorated
Solution Approach 1:
Instead of requiring complete autonomous determination or complete base station control, the solution uses partial action where the terminal autonomously selects time units based on pre-configured rules from the base station. This partial autonomy maintains operational flexibility while the pre-configured rules ensure consistency with base station understanding, avoiding the reliability issues of full autonomy.
3Reliability
If indication information is provided to specify time units, then the understanding consistency is improved, but the signaling overhead is increased
Solution Approach 1:
The indication information uses parameter changes in the existing uplink grant structure to specify time unit selections. By modifying parameters within the existing signaling framework rather than introducing entirely new signaling messages, the solution achieves improved understanding consistency between terminal and base station while minimizing the increase in signaling overhead.

AI summary
The present disclosure provides an information transmission method and apparatus, and a storage medium. The method comprises: if uplink information to be sent needs to occupy multiple time units, and the multiple time units include at least two types of time units, determining from the multiple time units a first time unit for uplink transmission; and on the first time unit, sending the uplink information to a base station. The present disclosure can ensure that a terminal and a base station have a consistent understanding of time domain resources for transmitting uplink information, thereby improving the reliability of uplink transmission and the reliability of full-duplex communication.
