Antenna Panel Configuration Using Update Timer for Wireless Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in complex environments where signal attenuation or blocking undermines established channel measuring and reporting mechanisms, leading to inefficiencies in managing finite wireless channel resources.
Innovation Solution
A method where a user equipment (UE) autonomously applies an antenna panel configuration based on reporting configuration information transmitted to a network entity, using an update timer to determine when to activate the configuration, thereby reducing latency and improving communication reliability without waiting for explicit signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE waits for explicit signaling from the network entity to apply antenna panel configuration, then the network entity can confirm the configuration, but the communication latency increases and reliability decreases when signaling is lost or outdated
Solution Approach 1:
The UE performs preliminary actions by autonomously determining and applying the antenna panel configuration based on previously received configuration information and reported beam/antenna panel metrics, before receiving explicit confirmation signaling from the network entity. This allows the UE to proactively configure its antenna panel, reducing latency while the network entity subsequently confirms or adjusts the configuration.
2Productivity
If the UE autonomously applies antenna panel configuration without waiting for explicit signaling, then the communication latency is reduced, but the risk of applying outdated or incorrect configuration increases
Solution Approach 1:
The network entity provides feedback to the UE by receiving reports containing beam metrics and antenna panel information, and by sending configuration information and explicit signaling to confirm or adjust the antenna panel configuration. This feedback loop ensures that the UE's autonomous configuration decisions are based on current network conditions and are validated by the network entity, maintaining configuration accuracy while enabling faster application.
3Reliability
If the network entity sends frequent explicit signaling to update antenna panel configuration, then the configuration accuracy is maintained, but the signaling overhead and network resources are consumed
Solution Approach 1:
The UE performs self-service by autonomously determining and applying antenna panel configurations based on its own measurements of beam metrics and antenna panel information, combined with previously received configuration information. This reduces the need for frequent explicit signaling from the network entity, thereby reducing signaling overhead while maintaining reasonable configuration accuracy through the UE's autonomous decision-making capability.

AI summary
Certain aspects of the present disclosure provide techniques for configuring a user equipment (UE) to communicate with a network entity based on a selected antenna panel reported to a network entity. An example method generally includes transmitting, to a network entity, a report including information associated with an antenna panel selected for communications between the user equipment and the network entity; selecting a starting time and a wait time to apply a configuration associated with the selected antenna panel; activating an update timer based on the starting time and the wait time; and communicating with the network entity based on the configuration associated with the selected antenna panel after expiry of the update timer.
