Configured Uplink Resource Transmission Control in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in E-UTRAN networks, face inefficiencies in uplink resource utilization due to suboptimal scheduling and battery waste when no data is available for transmission, leading to increased latency and resource wastage.
Innovation Solution
Implementing a method where user equipment (UE) receives a configured uplink resource signaling and performs transmissions only when data is available, using the resource in designated transmission time intervals (TTIs) and not wasting resources by transmitting padding or using the resource in non-active times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs transmission using configured uplink resource in every TTI where the resource is available, then the resource utilization appears consistent and predictable, but battery power is wasted when no data is available for transmission
Solution Approach 1:
The patent applies dynamics by making the UE's transmission behavior adaptive rather than static. The UE dynamically adjusts whether to transmit in a configured TTI based on real-time data availability conditions. When data is available, the UE transmits; when no data is available, the UE skips transmission. This dynamic adjustment resolves the contradiction between maintaining consistent resource utilization and avoiding unnecessary battery consumption.
2Productivity
If the UE transmits padding data to utilize configured uplink resources, then resource allocation efficiency improves, but latency increases and battery power is wasted
Solution Approach 1:
The patent extracts and removes the unnecessary padding data transmission component from the system. Instead of forcing transmissions with padding when no real data is available, the invention allows the UE to skip transmissions entirely when the data buffer is empty. This extraction of the harmful padding transmission practice resolves the contradiction by eliminating waste without compromising resource allocation efficiency for actual data.
3Measurement precision
If the UE monitors for signaling in every TTI to determine whether to transmit, then transmission accuracy improves, but processing complexity and battery consumption increase
Solution Approach 1:
The patent applies preliminary action by having the network pre-configure uplink resources and provide advance signaling to the UE about available transmission opportunities. The UE receives signaling in advance that indicates which TTIs have configured uplink resources, allowing it to prepare for transmissions without continuous complex monitoring. This preliminary configuration simplifies the UE's processing while maintaining accurate transmission timing.

AI summary
A method and apparatus for using a configured resource by a user equipment in a wireless communication system. In one embodiment, the method includes receiving a signaling to configure an uplink resource which is available in multiple transmission time intervals (TTIs), including a first TTI and a second TTI. The method includes performing a transmission using the uplink resource in the first TTI in response to reception of the signaling and not in the second TTI which is not corresponding to reception of the signaling, wherein the UE has no data available for transmission.
