Antenna Panel Beam Failure Detection via Reference Signal Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies cannot accurately determine which antenna panel in a user device experiences a beam failure, as the base station receives general beam failure information without specific panel identification, leading to inefficient resource allocation and recovery processes.
Innovation Solution
Establishing an association relationship between reference signal sets and antenna panels based on configuration information, detecting signal quality, and sending specific beam failure information to the base station to identify the failed panel, allowing for precise determination and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user device sends general beam failure information to the base station, then the base station can determine that a beam failure occurs, but the base station cannot identify which specific antenna panel experiences the failure
Solution Approach 1:
The patent segments the beam failure detection by dividing the antenna system into multiple independent antenna panels, each with its own reference signal set. The failure detection is then segmented to identify which specific panel experiences failure, rather than treating the entire antenna system as a single unit. This is achieved by establishing associations between reference signal sets and specific antenna panels, allowing precise identification of the failed panel.
2Ease of operation
If the base station receives beam failure information without panel identification, then the communication process is simplified, but resource allocation and recovery processes become inefficient
Solution Approach 1:
The patent implements a feedback mechanism where the user device detects beam failure on a specific antenna panel and sends back identification information about which panel failed. This feedback loop enables the base station to receive not just the notification of failure, but also precise information about which antenna panel is affected, allowing for targeted resource allocation and recovery actions without complicating the overall reporting process.

AI summary
A method for determining an antenna beam failure includes: establishing, according to received first configuration information, an association relationship between n reference signal sets and n antenna panels, in which the i-th reference signal set is associated with the i-th antenna panel; detecting all reference signals in at least one of the n reference signal sets to determine whether a failed antenna panel having a beam failure exists in at least one antenna panel associated with the at least one reference signal set; and sending to a base station beam failure information indicating that the failed antenna panel has a beam failure in response to determining that the failed antenna panel exists.
