Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR systems lack components for self-interference measurement and reporting, which are essential for effective beam management in beam-specific downlink and uplink operations, leading to inefficiencies in wireless communication.
Innovation Solution
The implementation of a user equipment (UE) with a transceiver and processor configured to transmit and receive reference signals, measure signal qualities, and perform measurement reporting using multiple antenna ports, enabling self-interference measurement and reporting in wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beam-specific operations are implemented in 5G NR systems, then wireless communication efficiency is improved, but self-interference measurement capability deteriorates (lacks components)
Solution Approach 1:
The patent divides the antenna system into multiple antenna ports (first set and second set) that can be independently configured. The first antenna ports are used for transmitting uplink reference signals while the second antenna ports are used for measuring signal qualities, including self-interference measurements. This segmentation allows simultaneous beam-specific operations and accurate self-interference measurement without mutual interference.
2Adaptability or versatility
If multiple antenna ports are used for beam management, then beam-specific operations are enhanced, but device complexity increases
Solution Approach 1:
The patent configures the user equipment with multiple antenna ports that serve multiple functions: the first antenna ports transmit uplink reference signals while the second antenna ports perform both downlink signal reception and self-interference measurement. This multi-functional design enables comprehensive beam management capabilities without proportionally increasing device complexity, as the same hardware infrastructure supports multiple operational modes.
3Measurement precision
If self-interference measurement is added to current 5G NR systems, then measurement accuracy is improved, but system complexity increases
Solution Approach 1:
The patent combines self-interference measurement functionality with existing downlink signal reception operations. The second antenna ports are configured to receive both downlink reference signals from the base station and transmitted uplink reference signals for self-interference measurement. By merging these measurement functions into existing reception pathways, the system achieves accurate self-interference measurement without adding separate dedicated measurement hardware, thus limiting the increase in system complexity.

AI summary
A user equipment (UE) is configured to perform a method for measuring and reporting multi-beam operations. The UE includes a transceiver configured to communicate via a multi-beam operation with a base station. The UE further includes a processor operably connected to the transceiver. The processor is configured to at least one of: transmit, via the transceiver through a first set of antenna ports, one or more uplink (UL) reference signals (RSs), or receive, via the transceiver, one of: one or more downlink (DL) RSs transmitted by a base station (BS), or the one or more transmitted UL RSs, measure, via the transceiver using a second set of antenna ports, signal qualities of the one or more UL RSs and the one or more DL RSs for a time period, and perform measurement reporting of the measured signal qualities.
