Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications networks, the simultaneous transmission of scheduling request (SR) and hybrid automatic repeat request (HARQ) information on overlapping time-frequency resources leads to processing and transmission latency issues, affecting user equipment performance.
Innovation Solution
A method for determining and configuring time-frequency resources for SR and HARQ information to ensure non-overlap, allowing for separate transmission on distinct resources to meet latency requirements, including scenarios where SR information is sent on a first resource and HARQ information on a second resource, or vice versa, to optimize processing and transmission times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If SR information and HARQ information are simultaneously sent on the time-frequency resource corresponding to SR information, then SR information transmission is achieved, but HARQ information processing latency and transmission latency cannot be met
Solution Approach 1:
The patent segments the time-frequency resources into distinct resources for SR information and HARQ information. When resources overlap, the method determines separate transmission resources for both information types, ensuring HARQ information is transmitted with sufficient processing time while maintaining SR information transmission efficiency.
Solution Approach 2:
The patent applies preliminary action by determining the time-frequency resources for both SR and HARQ information in advance before transmission. The method calculates and reserves appropriate resources beforehand, ensuring that when transmission occurs, both information types have dedicated time-frequency slots that meet their respective latency requirements.
2Loss of time
If SR information and HARQ information are simultaneously sent on the time-frequency resource corresponding to HARQ information, then HARQ information transmission is achieved, but SR information receiving is delayed and uplink resource acquisition time is prolonged
Solution Approach 1:
The patent segments the transmission process by assigning distinct time-frequency resources to SR and HARQ information. When resource overlap occurs, the method identifies separate resources for both information types, ensuring SR information receives timely transmission while HARQ information maintains efficient transmission timing.
Solution Approach 2:
The patent performs preliminary resource determination for both SR and HARQ information transmission. By calculating and reserving appropriate time-frequency resources in advance, the method ensures that SR information is transmitted with sufficient time for receiving and processing, while HARQ information transmission efficiency is maintained.
3Loss of time
If time-frequency resources for SR and HARQ information are configured to be non-overlapping, then transmission latency requirements are met, but resource utilization efficiency decreases
Solution Approach 1:
The patent merges the resource determination process by simultaneously considering both SR and HARQ information requirements when allocating time-frequency resources. The method integrates both information types into a unified resource allocation strategy that minimizes overlap while ensuring latency requirements are met, thereby improving overall resource utilization efficiency.
Solution Approach 2:
The patent applies dynamic resource allocation by adjusting time-frequency resource assignments based on actual transmission conditions. The method dynamically determines optimal resources for both SR and HARQ information, allowing flexible configuration that reduces latency when needed while maximizing resource utilization efficiency through adaptive resource management.
