Incentive-Based Relay Prioritization for Wireless Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face delays due to UEs operating as relays, as they cannot transmit current data concurrently with relaying data, leading to signaling latency issues.
Innovation Solution
A base station configures UEs with priority schemes for relay and current data transmissions, allowing selective transmission based on priority values, using time-frequency resources and power allocations to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE operates as a relay to transmit relay data, then the relay data transmission is ensured, but the current data transmission is delayed or blocked
Solution Approach 1:
The patent changes the parameter of transmission priority by introducing a priority indicator that can take different values (e.g., 0 or 1) to indicate whether the UE should prioritize relay data or current data. This parameter change allows dynamic adjustment of transmission behavior based on network conditions and data importance, resolving the contradiction between ensuring relay data transmission and minimizing current data latency.
Solution Approach 2:
The patent makes the transmission priority dynamic by allowing the base station to configure different priority indicators for different UEs and different time periods. The UE can switch between prioritizing relay data and current data based on the configured priority indicator, enabling adaptive response to changing network conditions rather than a fixed static priority scheme.
2Productivity
If the UE transmits both relay data and current data simultaneously, then both data transmissions are maintained, but the resource allocation complexity increases
Solution Approach 1:
The patent simplifies resource allocation complexity by introducing a priority indicator parameter that directly determines resource allocation decisions. When the priority indicator indicates relay data has higher priority, the UE uses pre-configured relay resources; when current data has higher priority, the UE uses its own uplink resources. This parameter-based decision rule avoids complex real-time resource negotiation and allocation algorithms.
3Loss of time
If the UE prioritizes current data transmission over relay data, then the current data latency is reduced, but the relay data transmission reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the base station monitors network conditions, data importance, and UE status, then configures appropriate priority indicators to UEs. This feedback loop ensures that when relay data reliability is critical, the base station sets the priority indicator to favor relay transmission, while when current data latency is more important, it adjusts the indicator accordingly, dynamically balancing the two competing requirements.

AI summary
Methods, systems, and devices for wireless communications are described. A base station may transmit signaling to a user equipment (UE) indicating one or more resources for a relay data transmission and a priority scheme for the relay data transmission and a current data transmission. The priority scheme may indicate a priority value for the relay data transmission and the current data transmission. The UE may selectively transmit the relay data transmission, the current data transmission, or both based on the priority scheme. If the priority scheme indicates the current data transmission has a higher priority than the relay data transmission, then the UE may transmit the current data transmission using the resources. If the priority scheme indicates the current data transmission has a lower priority than the relay data transmission, then the UE may transmit the relay data transmission using the resources.
