Uplink Panel Selection Power Saving 5G
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in Next Generation Radio Access Networks (NG-RAN) and 5G networks, there is a challenge in maintaining reliable uplink communications while managing power consumption by dynamically activating and deactivating antenna panels due to user equipment (UE) movement and rotation, which introduces complexities in panel status understanding between the UE and the network nodes.
Innovation Solution
The solution involves a method for uplink panel selection that includes monitoring uplink slots for the absence of signals to detect deactivated panels, registering their deactivation, and activating alternative panels, with the UE reporting status messages indicating activation or deactivation, including scheduling offsets, to maintain consistent panel status understanding between the UE and network nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If antenna panels are dynamically activated and deactiv ated to manage power consumption, then power savings are improved, but communication reliability deteriorates due to panel status mismatch between UE and network nodes
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports panel status changes to the network node. When a panel is deactivated or activated, the UE sends status messages (e.g., panel status reports, beam failure recovery indicators) to inform the network node of the current panel state, ensuring both sides have consistent understanding and maintaining communication reliability while enabling power savings through dynamic panel management
Solution Approach 2:
The patent employs preliminary actions by establishing panel status reporting mechanisms before communication issues arise. The UE proactively reports panel deactivation/activation status to the network node, so that when panel switching occurs, the network node is already aware and can adjust its transmission accordingly, preventing communication failures
2Reliability
If panel status reporting is implemented to maintain consistent understanding, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent utilizes self-service mechanisms where the UE autonomously monitors its own panel status and automatically generates status reports when changes occur. The UE independently determines when to report (based on internal panel state changes) and sends appropriate messages without requiring complex external coordination, reducing overall system complexity while maintaining reliability
Solution Approach 2:
The patent changes the parameter of panel status reporting from continuous to event-driven. Instead of constantly reporting panel status, the UE only reports when actual status changes occur (activation or deactivation), reducing the frequency and volume of status messages while ensuring the network node has up-to-date information, thereby lowering complexity
3Use of energy by moving object
If uplink slots are monitored for absence of signals to detect deactivated panels, then power savings are improved, but processing delays increase
Solution Approach 1:
The patent applies preliminary action by having the UE proactively report panel status changes before the network node would need to detect them through monitoring. When the UE deactivates or activates a panel, it immediately sends a status report, allowing the network node to know the current panel state in advance, eliminating the need for time-consuming signal absence monitoring and reducing detection delays

AI summary
Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.
