Innovation Solution
A method and apparatus for user equipment (UE) and base station (BS) that utilize full duplex carrier resource blocks (FD CRBs) to control signal transmission and reception, including identifying resource elements for uplink data transmission and reception based on FD CRB information, with self-interference cancellation techniques to manage duplex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full duplex operation is implemented to increase data transmission efficiency, then productivity is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the full duplex operation mode based on channel conditions and power constraints. The UE can switch between full duplex and half duplex modes depending on the downlink reference signal received power (DL-RSRP) and other parameters, allowing the system to optimize between productivity and power consumption in real-time
Solution Approach 2:
The patent changes operational parameters such as the set of resource blocks used for full duplex transmission based on channel conditions. By adjusting parameters like the resource block set configuration and transmission power levels, the system achieves efficient full duplex operation when conditions permit while reducing power consumption when conditions are unfavorable
2Productivity
If full duplex operation is used to enhance spectral efficiency, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the frequency resources into different sets of resource blocks, designating specific blocks for full duplex operation and others for conventional operation. This segmentation allows the complex full duplex functionality to be applied only to specific portions of the spectrum rather than the entire system, reducing overall device complexity while maintaining spectral efficiency benefits where applicable
Solution Approach 2:
The patent designs the full duplex mechanism to be configurable and adaptable, where the same basic framework can support different resource block sets and operational modes. This multi-functionality allows the system to handle both full duplex and conventional modes using the same UE architecture, reducing the complexity burden
3Productivity
If resource allocation is optimized for full duplex operation, then productivity is improved, but measurement precision requirements increase
Solution Approach 1:
The patent employs feedback mechanisms where the UE reports channel state information and power consumption measurements to the network. Based on this feedback, the network adjusts the full duplex resource allocation dynamically. This feedback loop allows the system to achieve efficient resource allocation while managing measurement precision requirements through adaptive rather than static configuration
