Configured Grant Skipping in Full-Duplex Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in full-duplex networks lack mechanisms for user equipment (UE) to consider factors beyond the presence or absence of data in the uplink buffer during configured grant (CG) skipping operations, leading to inefficient data transmission due to neglect of interference profiles and data characteristics.
Innovation Solution
The UE analyzes interference profiles, including self-interference (SI) and cross-link interference (CLI), and considers latency, size, and age of data to determine whether to perform or skip CG-based uplink transmissions, weighing the impact of interference against data parameters to optimize skipping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs CG-based uplink transmission whenever data is present in the uplink buffer, then data transmission reliability is improved, but interference to the network is increased
Solution Approach 1:
The patent changes the decision parameter for CG transmission from a simple binary condition (data present/absent) to a multi-parameter evaluation including interference profile, data latency, data size, and data age. This allows the UE to adapt transmission decisions based on current network conditions and data characteristics, reducing unnecessary transmissions that cause interference while maintaining reliable data delivery.
Solution Approach 2:
The patent introduces feedback mechanisms where the UE evaluates interference profiles and data characteristics before making transmission decisions. The network can provide interference profile information to the UE, and the UE uses this feedback along with local data state information to make informed decisions about whether to perform CG transmissions, thereby reducing harmful interference while maintaining transmission reliability.
2Object-generated harmful factors
If the UE skips CG-based uplink transmission to reduce interference, then network interference is reduced, but data transmission efficiency is worsened
Solution Approach 1:
The patent makes the CG transmission decision dynamic by continuously evaluating multiple parameters including interference profile, data latency requirements, data size, and data age. Instead of a static transmission policy, the UE adapts its transmission behavior based on real-time conditions, skipping transmissions only when data characteristics and interference levels justify doing so, thereby maintaining transmission efficiency while reducing interference.
Solution Approach 2:
The patent applies preliminary action by having the UE evaluate interference profiles and data characteristics before making transmission decisions. The network can pre-configure interference profile thresholds and data parameter thresholds, allowing the UE to make rapid decisions without real-time network intervention, thus maintaining transmission efficiency while proactively reducing interference.
3Productivity
If the UE considers multiple factors (interference profile, latency, size, age) for skipping decisions, then data transmission optimization is improved, but device complexity is increased
Solution Approach 1:
The patent segments the complex decision-making process into distinct evaluation components: interference profile evaluation, data latency assessment, data size assessment, and data age assessment. Each component can be evaluated independently using pre-configured thresholds, and the final transmission decision is made by combining these segmented evaluations. This modular approach reduces device complexity while maintaining comprehensive optimization.
Solution Approach 2:
The patent enables the UE to autonomously evaluate its own data characteristics (latency, size, age) and compare them against pre-configured thresholds without requiring real-time network intervention. The UE serves itself by making informed transmission decisions based on local information and pre-configured parameters, reducing the complexity of real-time coordination while achieving optimized data transmission.

AI summary
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine that an uplink buffer includes data to be communicated in a configured grant based uplink transmission. The UE may identify an interference profile associated with the UE performing the configured grant based uplink transmission. The UE may perform a skipping operation for the configured grant based uplink transmission based at least in part on the data in the uplink buffer and the interference profile, wherein the skipping operation comprises either performing the configured grant based uplink transmission or skipping the configured grant based uplink transmission.
