Subband Full Duplex Resource Control for Mixed Repetition Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in resource allocation and interference management for uplink and downlink transmissions, particularly in scenarios where subband full duplex is employed, leading to poor uplink performance and resource contention.
Innovation Solution
The implementation of mechanisms for determining resource allocation across mixed uplink and downlink bandwidth parts and subbands, using resource control messages to ensure consistent resource allocation for repetitions, allowing transmissions to occur across both types of bandwidths, and utilizing power control parameters to manage interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmissions are restricted to only uplink subband or only uplink bandwidth part, then interference is reduced, but resource utilization and transmission reliability deteriorate
Solution Approach 1:
The patent segments the frequency spectrum into distinct uplink subbands and uplink bandwidth parts, allowing transmissions to be selectively allocated to different segments based on channel conditions and interference levels. This segmentation enables the system to achieve both high reliability (by avoiding interfered segments) and high resource utilization (by using available segments).
Solution Approach 2:
The patent implements dynamic resource allocation where the determination of whether repetitions can be transmitted across mixed uplink subband and bandwidth part changes based on real-time channel conditions, interference measurements, and transmission requirements. This dynamic approach allows the system to adaptively optimize both reliability and resource utilization.
2Reliability
If resource allocation is inconsistent across repetitions, then resource management complexity is reduced, but transmission reliability deteriorates
Solution Approach 1:
The patent applies local quality by allowing different resource allocation strategies for different repetitions based on their specific requirements and channel conditions. Each repetition can be allocated resources locally optimized for its transmission needs, improving overall reliability while maintaining manageable complexity through localized decision-making.
Solution Approach 2:
The patent implements feedback mechanisms where the network node monitors transmission outcomes and channel conditions, then adjusts resource allocation for subsequent repetitions accordingly. This feedback loop ensures consistent resource management that maintains high transmission success rates while preventing excessive complexity through rule-based adjustments.

AI summary
This disclosure is generally directed to wireless communication systems and methods, and particularly relates to resource control for wireless transmission with repetitions based on subband full duplex. The various implementations concern determination of conditions under which the various repetitions of an uplink (or downlink) wireless transmission are allowed to be transmitted in a mixed manner across an uplink (or downlink) bandwidth part and an uplink (or downlink) subband within an otherwise downlink (or uplink) bandwidth part. Various mechanisms for determining resources for the transmission of the repetitions based on one or more resource identification fields in a resource control message for scheduling the wireless transmission are further disclosed. Such mechanisms provide consistent resource allocation between the repetitions transmitted in the mixed manner.
