Traffic-Aware Channel State Feedback for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a mechanism to dynamically select transmission parameters that satisfy varying objectives under given constraints, leading to inefficiencies such as wasteful payload maximization or failure to meet urgent message deadlines.
Innovation Solution
Wireless communication devices receive resource allocation mode and traffic parameter indications to select transmission parameters based on a reference signal, allowing for dynamic optimization along time, frequency, or spatial dimensions, and can fallback or transition to alternative modes to meet constraints like payload size or delivery deadlines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE selects transmission parameters that maximize payload size, then the number of bits transmitted in a single time frame is increased, but resource blocks are wasted on small messages and urgent messages with deadlines cannot be prioritized
Solution Approach 1:
The patent implements dynamic selection of transmission parameters by the UE based on received indications from the BS. The UE can transition between different resource allocation modes (e.g., from payload maximization mode to deadline-aware mode) depending on traffic conditions and BS requests, making the system adaptable rather than static
Solution Approach 2:
The patent changes the parameters used for transmission parameter selection by introducing new indicators from the BS (resource allocation mode indication, traffic parameter indication). These parameter changes enable the UE to switch between different optimization objectives, such as maximizing payload size versus meeting delivery deadlines or minimizing resource block usage
2Ease of operation
If the UE uses a single resource allocation mode for all transmissions, then the system is simple to operate, but it cannot adapt to varying traffic objectives and constraints
Solution Approach 1:
The patent makes the UE multi-functional by enabling it to operate in multiple resource allocation modes. The UE can universally handle different traffic types (small messages, large messages, urgent messages with deadlines) by selecting appropriate transmission parameters based on BS indications, rather than being dedicated to a single function
Solution Approach 2:
The system transitions from a static single-mode operation to dynamic multi-mode operation. The UE can switch between resource allocation modes in real-time based on traffic conditions and BS requests, allowing adaptability while maintaining operational simplicity through automated mode selection

AI summary
Wireless communication devices, systems, and methods relate to selecting transmission parameters that optimize a dimension (e.g., time, frequency, and/or spatial) under a set of constraints. A UE may receive a resource allocation mode indication and a traffic parameter indication from a BS. The resource allocation mode indication informs the UE to optimize along a time dimension, a frequency dimension, and/or a spatial domain. The traffic parameter indication informs the UE what constraints to consider for the transmission parameters. The UE may use this information upon receipt of a reference signal in selecting transmission parameters based on the received reference signal, resource allocation mode indication, and traffic parameter indication. The resource allocation mode may correspond to optimization within a single slot or across multiple slots. Once selected, the UE may transmit the transmission parameters to the BS for use in sending the message to the UE.
