Full-Duplex RBW Configuration for Joint DL/UL Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face interference and congestion due to increased demand for mobile broadband access, leading to degraded performance in both downlink and uplink transmissions, particularly in full-duplex modes, where switching between bandwidth parts (BWPs) causes delays and wastes network resources.
Innovation Solution
Implementing flexible and quick adjustments of resource bandwidths (RBWs) within bandwidth parts (BWPs) to enable joint uplink and downlink operations, allowing for seamless transitions without BWP switching delays, thereby optimizing network bandwidth and spectrum usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bandwidth part (BWP) switching is used to adjust resource bandwidths, then network adaptability is improved, but switching delays and resource waste occur
Solution Approach 1:
The patent segments the bandwidth part configuration into multiple resource bandwidth (RBW) configurations within a single BWP. Instead of switching entire BWPs, the system divides the BWP into configurable RBW segments that can be independently adjusted. This allows the network to adapt resource bandwidths by selecting different RBW configurations without triggering BWP switching delays, thus maintaining adaptability while eliminating time loss.
2Productivity
If resource bandwidth adjustments are made frequently, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic RBW configuration adjustment within the BWP framework. The system allows flexible switching between multiple pre-defined RBW configurations (first RBW configuration, second RBW configuration, etc.) based on network conditions. This dynamic adjustment mechanism enables frequent resource optimization without requiring complex system restructuring, as the switching occurs within the existing BWP architecture rather than requiring full BWP reconfiguration.
3Adaptability or versatility
If separate uplink and downlink bandwidth configurations are used, then transmission flexibility is improved, but resource utilization decreases
Solution Approach 1:
The patent merges uplink and downlink resource bandwidth configurations into a unified RBW configuration framework within the BWP. Instead of maintaining completely separate configurations for uplink and downlink, the system uses a single BWP structure that can accommodate multiple RBW configurations serving both uplink and downlink transmissions. This unified approach allows flexible transmission configurations while improving resource utilization by eliminating redundant separate configuration overhead and enabling better resource sharing between uplink and downlink.

AI summary
In one aspect, a method of wireless communication includes receiving, by a wireless communication device during a slot, first data according to a first resource bandwidth (RBW) configuration of a bandwidth part (BWP) configuration, where the BWP configuration is configured for uplink and downlink operations. The method further includes transmitting, by the wireless communication device during the slot, second data according to a second RBW configuration of the BWP configuration, where the second RBW configuration is different from the first RBW configuration. Other aspects and features are also claimed and described.
