Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional scheduling assignment (SA) method for indicating transmission resources in communications leads to domain waste and low transmission reliability due to limited payload and variable transmission quantities.
Innovation Solution
A method and device for indicating transmission resources by selecting N transmissions based on a target indication rule, where N is the maximum quantity of transmissions indicated by control information, and transmitting these resources in a cyclic manner using a scheduling assignment (SA).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the SA indicates resources of N transmissions in total, then the receiving terminal knows resource occupation status more clearly, but invalid fields appear in the SA when current transmission is not among the N indicated transmissions, causing domain waste
Solution Approach 1:
The patent applies dynamics by making the SA indication adaptive to the current transmission state. The network side dynamically determines whether to indicate N transmissions or N-1 transmissions based on whether the current transmission is included in the indicated transmissions. This dynamic adjustment prevents invalid fields from appearing in the SA, eliminating domain waste while maintaining reliable transmission indication.
2Device complexity
If the SA payload is limited, then the complexity of blind detection is reduced, but the quantity of transmissions that can be indicated is variable and insufficient, leading to invalid fields and domain waste
Solution Approach 1:
The system dynamically adjusts the indication capacity based on the current transmission state. When the current transmission is among the N indicated transmissions, the SA indicates N transmissions; when it is not, the SA indicates N-1 transmissions. This dynamic adaptation maximizes the utilization of the fixed SA payload, preventing domain waste while maintaining manageable detection complexity.
3Quantity of substance
If the initial transmission is only indicated once, then the SA payload is saved, but if the SA fails to be decoded, the position of the resource cannot be obtained, reducing transmission reliability
Solution Approach 1:
The patent applies preliminary action by ensuring that the initial transmission resource is always included in the N indicated transmissions when the current transmission is an initial transmission. This guarantees that the receiving terminal always obtains the resource position information for the initial transmission, improving reliability without significantly increasing payload usage.
Solution Approach 2:
The system uses feedback mechanisms where the network side determines the indication strategy based on the current transmission state and historical information. This feedback loop ensures that the SA indication always includes necessary transmission resources, improving reliability while optimizing payload utilization.
