Multi-Array Beamlock for Independent Tx and Rx Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UE conformance test functions struggle to simultaneously lock multiple transmitting and receiving beams across multiple active antenna arrays, which is necessary for advanced 3GPP Release 18 features like multi-Rx and full-duplex UEs, due to limitations in current beamlock mechanisms.
Innovation Solution
A beamlock scheme is introduced to independently lock transmitting and receiving beams on multiple active antenna arrays through a beamlock message or command, allowing for flexible and efficient control of beamlock operations using array IDs and RRC signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single beamlock mechanism is used for conventional UEs, then beamlocking works for single antenna arrays, but it cannot simultaneously lock multiple transmitting and receiving beams across multiple active antenna arrays
Solution Approach 1:
The beamlock mechanism is segmented into separate transmitting beamlock and receiving beamlock operations. Each beamlock message includes independent indication fields for Tx beamlock and Rx beamlock, allowing them to be controlled and locked independently on different antenna arrays simultaneously
Solution Approach 2:
The beamlock mechanism is extended from a single-dimension (single antenna array) to multi-dimension by adding antenna array identification fields and supporting multiple antenna arrays. The beamlock message structure includes array ID indicators that enable addressing and locking beams on multiple antenna arrays concurrently
2Adaptability or versatility
If beamlock is implemented for multiple antenna arrays, then advanced 3GPP Release 18 features are supported, but the beamlock message structure and control mechanism become more complex
Solution Approach 1:
The beamlock message structure is designed with universal fields that can indicate multiple antenna arrays and both transmitting and receiving beams. The same message format and indication fields are used regardless of whether one or multiple antenna arrays are involved, making the mechanism universally applicable to both conventional and advanced UE types
Solution Approach 2:
The beamlock indication fields are enhanced with additional parameters including antenna array ID indicators and beam type specifications. These parameter extensions allow the same basic beamlock mechanism to accommodate both single-array conventional UEs and multi-array advanced UEs by simply changing the activated parameters in the message

AI summary
Example embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage medium for beamlock on a plurality of antenna arrays. In a method, a first apparatus receives a beamlock message from a second apparatus. The beamlock message indicates that one or more transmitting beams are to be locked on a first list of antenna arrays and/or one or more receiving beams are to be locked on a second list of antenna arrays. Based on the beamlock message, the first apparatus performs beamlock of the one or more transmitting beams and/or the one or more receiving beams.
