Dynamic Beam Correspondence Control in 5G Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication devices face inefficiencies in power consumption and beam management due to mandatory beam correspondence (BC) requirements, particularly in scenarios with unbalanced data flow or when full polarization control is not feasible, leading to potential compliance issues and increased power usage.
Innovation Solution
Implementing dynamic control operations in wireless communication devices to temporarily enable or disable BC based on predetermined conditions, such as data load imbalances or proximity to the base station, allowing for independent beam management processes for uplink and downlink operations and signaling to the network access node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beam correspondence is mandatorily applied, then beam management is simplified, but power consumption increases and compliance issues arise in unbalanced data flow scenarios
Solution Approach 1:
The patent applies dynamics by making beam correspondence configurable rather than fixed. The system can dynamically switch between BC enabled and disabled modes based on operational conditions, allowing the UE to adapt beam management behavior to current data flow requirements and network conditions, thereby reducing power consumption when full BC is not needed.
Solution Approach 2:
The patent changes the parameter of beam correspondence from a mandatory fixed state to a configurable state that can be enabled or disabled based on conditions. This parameter change allows the system to optimize between simplicity and power consumption by adjusting BC availability according to actual operational needs.
2Ease of operation
If beam correspondence is mandatorily applied, then beam management is simplified, but compliance issues arise when full polarization control is not feasible
Solution Approach 1:
The system dynamically adjusts beam correspondence availability based on whether the UE can fulfill full polarization control requirements. When polarization control is not feasible, the system can disable BC mode, avoiding compliance violations while maintaining operational simplicity when conditions permit.
Solution Approach 2:
The patent changes the compliance parameter by making beam correspondence optional rather than mandatory. This allows the system to adapt to varying polarization control capabilities and maintain reliability by disabling BC when full compliance cannot be achieved, while still benefiting from simplified beam management when compliance is possible.
3Adaptability or versatility
If beam correspondence is applied, then uplink and downlink beam patterns are unified, but adaptability to unbalanced data flow scenarios is reduced
Solution Approach 1:
The patent applies dynamics by making beam correspondence configurable based on data flow conditions. When data flow is balanced, BC can be enabled for unified beam patterns. When data flow is unbalanced, the system can disable BC to gain adaptability, thus resolving the contradiction between unity and adaptability through dynamic configuration.

AI summary
A wireless communication device includes a wireless interface for conducting wireless communications with a network access node of a wireless network, the wireless interface having uplink and downlink beam forming capabilities. The wireless communication device further includes a control circuit configured to detect a predetermined condition and, in response to the detection, temporarily operate the wireless interface without beam correspondence between uplink and downlink operations; and transmit a message to the network access node that beam correspondence is not used by the wireless communication device.
