Wireless Node Resource Configuration for Overlapping Time Domain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, resource assignment is often inefficient, leading to suboptimal utilization of resources in both time and frequency domains, particularly in integrated access and backhaul systems where simultaneous operations are challenging due to overlapping resource sets.
Innovation Solution
The proposed solution involves a method and apparatus for resource configuration in wireless communication systems, where a wireless node receives scheduling information for a physical channel on one set of resources and information about overlapping resources from another entity, determining availability and transmitting indications of resource validity or performing communications based on availability, thereby optimizing resource use for simultaneous downlink and uplink operations.

Engineering Contradiction Analysis
1Productivity
If resources are assigned for communication in integrated access and backhaul systems, then communication operations can be performed, but resource utilization becomes inefficient due to overlapping resource sets in time domain
Solution Approach 1:
The patent applies preliminary action by determining the availability of first resources based on second resources before actual communication operations occur. The wireless node proactively checks resource availability and receives indications of resource validity in advance, preventing conflicts between downlink and uplink transmissions before they happen. This advance planning allows for more efficient resource allocation and reduces time domain overlaps.
2Adaptability or versatility
If simultaneous downlink and uplink operations are performed on overlapping resources, then communication flexibility increases, but conflicts between transmissions occur
Solution Approach 1:
The patent implements feedback mechanisms where the wireless node receives indications from other entities about the validity of resources. When a resource is determined to be unavailable due to overlap, the system receives feedback indicating the resource is not valid, and the wireless node adjusts its transmission accordingly. This feedback loop ensures reliable simultaneous operations by preventing conflicts while maintaining flexibility in resource allocation.
3Productivity
If resource availability is determined dynamically, then resource allocation efficiency improves, but additional signaling and processing are required
Solution Approach 1:
The patent applies universality by using a unified resource indication mechanism that serves multiple purposes. The same signaling structure is used to indicate both resource availability and validity across different entities (wireless nodes, base stations). This multi-functional approach reduces overall signaling overhead compared to implementing separate indication mechanisms for each entity, while still enabling dynamic resource allocation efficiency.

AI summary
Apparatuses, methods, and systems are disclosed for resource configuration for wireless communication. One method includes receiving scheduling information for a physical channel on a first set of resources of a first entity. The method includes receiving information associated with a second set of resources of a second entity. The second set of resources overlap with the first set of resources in a time domain. The method includes determining an availability of a resource in the first set of resources based in part on the information associated with the second set of resources. The method includes, in response to determining that the resource is not available, transmitting an indication indicating that the resource is not valid. The method includes, in response to determining that the resource is available, performing a communication associated with the physical channel on the resource.
