Full Duplex Beam Pair Updating via Single Signaling Message
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing cell and full duplex beam pairs, leading to increased power consumption and resource utilization due to the need for separate messages for cell selection and beam pair indications, which can result in higher latency and resource usage during handover processes.
Innovation Solution
A method where a single message indicates both selected cells and uplink and downlink beam pairs for full duplex operation, allowing for simultaneous communication and reducing the need for multiple messages, thereby conserving computing, communication, and power resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If separate messages are used for cell selection and beam pair indications, then communication reliability is maintained, but power consumption and resource utilization increase
Solution Approach 1:
The patent combines cell selection indication and beam pair indication into a single message transmitted from base station to UE. This merging of previously separate signaling messages reduces the total number of messages exchanged, thereby reducing power consumption and resource utilization while maintaining communication reliability through the integrated message structure.
Solution Approach 2:
The single message serves multiple functions simultaneously: it indicates cell selection, indicates uplink beam pairs, and indicates downlink beam pairs. This multi-functionality eliminates the need for separate dedicated messages for each indication type, reducing overall signaling overhead and power consumption while ensuring all necessary communication parameters are conveyed reliably.
2Loss of time
If multiple messages are exchanged for cell and beam pair indication, then information completeness is ensured, but latency increases
Solution Approach 1:
The patent merges cell selection indication, uplink beam pair indication, and downlink beam pair indication into a single integrated message. This consolidation reduces the number of sequential message exchanges required during handover processes, thereby reducing latency while ensuring complete information transfer through the comprehensive structure of the unified message.
3Productivity
If separate signaling is used for cell selection and beam management, then signaling accuracy is maintained, but resource utilization increases
Solution Approach 1:
The single signaling message performs multiple functions: cell selection indication, uplink beam pair indication, and downlink beam pair indication. This multi-functional approach improves resource utilization by eliminating redundant message structures while maintaining signaling accuracy through precise encoding of all necessary parameters within the unified message framework.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that includes: an indication of one or more selected cells associated with one or more component carriers, and an indication of one or more uplink and downlink beam pairs for full duplex operation. The UE may transmit an uplink communication and receive a downlink communication based at least in part on the message. Numerous other aspects are described.
