Problem
Existing wireless communication technologies, such as LTE and NR, face challenges in optimizing resource allocation for full-duplex and non-full-duplex communications, leading to inefficiencies in spectral usage and interference management.
Innovation Solution
The method involves determining separate sets of time-frequency resources for full-duplex and non-full-duplex communications, each associated with distinct transmit powers, and transmitting/receiving corresponding transport formats to enable efficient resource utilization and interference mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate time-frequency resources are allocated for full-duplex and non-full-duplex communications, then spectral efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments time-frequency resources into distinct sets: a first set for full-duplex communications and a second set for non-full-duplex communications. This segmentation enables independent optimization of each communication mode, improving spectral efficiency by allowing simultaneous uplink and downlink transmissions in full-duplex mode while maintaining compatibility with traditional half-duplex operations in non-full-duplex mode.
Solution Approach 2:
The patent implements dynamic resource allocation where the network device can flexibly assign different time-frequency resources and transmit powers for full-duplex and non-full-duplex communications based on channel conditions, traffic requirements, and interference levels. This dynamic approach allows the system to adapt to varying operational demands while managing the complexity through standardized procedures.
2Object-generated harmful factors
If different transmit powers are used for full-duplex and non-full-duplex resources, then interference is reduced, but control complexity increases
Solution Approach 1:
The patent applies local quality by assigning different transmit powers to different time-frequency resource sets based on their specific communication modes. Full-duplex resources receive power allocation optimized for simultaneous transmission and reception, while non-full-duplex resources receive power allocation suited for traditional modes. This localized power control reduces self-interference in full-duplex mode and maintains compatibility in non-full-duplex mode.
Solution Approach 2:
The patent changes the power parameter dynamically based on the communication mode and channel conditions. The network device determines appropriate transmit powers for each resource set and communicates these parameters to the wireless communication device, enabling adaptive power control that reduces interference while managing complexity through parameter-based control mechanisms.
3Productivity
If multiple transport formats are transmitted in a slot, then resource utilization is improved, but processing complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing a unified resource allocation framework that can handle both full-duplex and non-full-duplex communications within the same slot structure. The same time-frequency resources can be utilized for different communication modes depending on the configured transport formats, enabling versatile resource usage without requiring completely separate processing paths for each mode.
