Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conformance testing for effective isotropic radiated power (EIRP) masks in wireless communication networks faces challenges due to uncertainty in beam selection and orientation, leading to potential interference and reduced data throughput, especially with higher frequency technologies.
Innovation Solution
A link establishment node (LEN) is used to transmit reference signals and beam lock commands to network nodes, aligning beamforming with real-world scenarios, and test equipment adjusts orientations to replicate UE positions, ensuring accurate EIRP mask compliance testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional EIRP mask conformance testing is performed without beam alignment, then testing can be conducted without complex coordination, but measurement accuracy is reduced due to uncertainty in beam selection and orientation
Solution Approach 1:
The patent applies preliminary action by performing beam selection and beam locking procedures before conducting EIRP mask measurements. The gNB configures the UE with beam failure recovery parameters and establishes a locked beam pair in advance, ensuring that measurements are taken with stable, predetermined beam orientations rather than uncertain, dynamically changing beams. This preliminary beam alignment resolves the contradiction by establishing measurement accuracy through pre-configured beam states.
Solution Approach 2:
The patent introduces beam failure recovery configuration and beam locking mechanisms as intermediary procedures between the gNB and UE. These intermediaries facilitate coordinated beam alignment by establishing explicit beam selection protocols, beam reporting mechanisms, and locked beam pair agreements. The intermediary beam management procedures enable accurate EIRP measurements while maintaining controlled complexity through standardized communication protocols.
2Productivity
If beam selection is performed dynamically during testing, then the system adapts to changing conditions, but uncertainty in beam orientation increases leading to interference and reduced data throughput
Solution Approach 1:
The patent resolves this contradiction by performing beam selection and establishment as preliminary actions before data transmission and EIRP testing. The gNB and UE exchange beam failure recovery configurations, perform beam reporting and selection, and establish locked beam pairs in advance. This preliminary beam alignment ensures high reliability and certainty in beam orientation during the actual testing and data transmission phases, eliminating the uncertainty that would otherwise reduce throughput.
Solution Approach 2:
The patent implements feedback mechanisms where the UE reports beam measurements and quality metrics to the gNB, which then adjusts beam selection and locking decisions. This feedback loop ensures that the most reliable beam pairs are identified and locked before testing, maximizing data throughput while maintaining beam selection certainty. The feedback-driven beam management resolves the contradiction by using measured performance data to establish stable beam configurations.
3Measurement precision
If comprehensive beam alignment procedures are implemented, then measurement accuracy improves, but testing duration increases
Solution Approach 1:
The patent extracts and separates the beam alignment and locking procedures from the actual EIRP measurement process. By performing beam failure recovery configuration, beam reporting, and beam pair locking as distinct preliminary steps before measurements begin, the patent enables comprehensive beam alignment to be completed once, establishing stable beams for all subsequent measurements. This extraction resolves the contradiction by consolidating time-consuming alignment activities into a one-time setup phase rather than repeating them for each measurement.
Solution Approach 2:
The patent applies preliminary action by completing all necessary beam selection, beam reporting, and beam locking configurations before initiating EIRP mask measurements. The gNB configures beam failure recovery parameters, the UE performs beam reporting and selection, and locked beam pairs are established in advance. This preliminary completion of alignment procedures ensures that measurements can proceed efficiently with pre-established stable beams, resolving the time-accuracy contradiction by front-loading the alignment activities.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a link establishment node (LEN) may transmit, using a first polarization, one or more reference signals that are configured for an effective isotropic radiated power (EIRP) conformance testing procedure for a network node. The LEN may transmit, based at least in part on expiration of a beam selection timer, a beam lock command that is directed to the network node. The LEN may transmit, based at least in part on transmitting the beam lock command, an indication of an uplink grant that is configured for the EIRP conformance testing procedure and is assigned to the network node. Numerous other aspects are described.
