Composite RIND for Low-Payload Wireless Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in handling low-payload messages due to excessive overhead in signaling and error detection codes, particularly in acknowledging communications from multiple devices, which leads to wasteful use of radio resources and increased complexity in application layers.
Innovation Solution
A method and system for generating and transmitting a composite reception indication (RIND) that combines individual RINDs for multiple low-payload messages, allowing devices to determine successful receipt and initiate corrections, while reducing overhead by using a single CRC for the composite RIND and leveraging predictability in traffic patterns for resource conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual RINDs are transmitted for each low-payload message, then acknowledgment reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent combines multiple individual RINDs into a single composite RIND that acknowledges multiple low-payload messages simultaneously. This merging approach maintains acknowledgment reliability for each message while significantly reducing signaling overhead by transmitting one composite indication instead of multiple separate indications.
Solution Approach 2:
The composite RIND serves multiple functions: it acknowledges multiple different low-payload messages from multiple UEs in a single transmission. This multi-functional approach allows one signal to perform what previously required multiple separate signals, reducing overall overhead while maintaining comprehensive acknowledgment coverage.
2Reliability
If error detection codes are added to each low-payload message, then transmission reliability is improved, but resource usage increases
Solution Approach 1:
The patent merges error detection capabilities at the composite RIND level rather than requiring separate error detection codes for each individual low-payload message. The base station generates a composite RIND that inherently provides acknowledgment and error detection for multiple messages, reducing the total resource consumption for error detection while maintaining reliability.
3Quantity of substance
If composite RIND is used to acknowledge multiple messages, then signaling overhead is reduced, but device complexity increases
Solution Approach 1:
The composite RIND is segmented into individual RIND components, each corresponding to a specific low-payload message or UE. This segmentation allows UEs to efficiently extract only their relevant acknowledgment information from the composite signal without processing the entire composite structure, thereby reducing individual device complexity while maintaining the overhead reduction benefits of the composite approach.
