Antenna Panel Training for Wireless Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a solution for effectively training and managing multiple antenna panels in terminal devices, which is essential for optimizing communication quality and reducing power consumption during wireless communication.
Innovation Solution
The method involves a network device configuring a reference signal resource set for a terminal device, allowing it to train and manage multiple antenna panels through different training modes (single-antenna panel, multi-antenna panel, or specified-antenna panel modes), using uplink and downlink reference signals to select optimal transmit and receive antenna panels, and reporting antenna panel capabilities to determine appropriate resource configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna panels are used simultaneously to cover different directions, then omnidirectional sending and receiving capability is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the antenna system into multiple independent antenna panels, each capable of being individually trained and managed. The network device configures separate reference signal resource sets for each antenna panel, allowing independent beam training and selection. This segmentation enables the terminal to activate only the necessary antenna panels for current communication needs, reducing overall system complexity while maintaining omnidirectional capability.
Solution Approach 2:
The patent implements dynamic antenna panel selection where the terminal device can flexibly switch between different antenna panels based on communication requirements. The network device configures multiple reference signal resource sets corresponding to different antenna panels, and the terminal can dynamically select which panels to activate and train, adapting the system complexity to the actual communication scenario rather than maintaining fixed high complexity.
2Reliability
If beam training is performed to select high-quality beams, then communication quality is improved, but training time and resource consumption increase
Solution Approach 1:
The patent performs beam training as a preliminary action before actual data transmission. The network device configures reference signal resource sets that enable the terminal to conduct beam training in advance, selecting optimal beams and antenna panels before communication begins. This preliminary beam training ensures high communication quality is established upfront, avoiding the need for continuous re-training during data transmission.
Solution Approach 2:
The patent implements partial beam training by configuring reference signal resource sets for only the necessary antenna panels rather than all available panels. The network device can selectively enable training for specific panels based on communication requirements, reducing the overall training time and resource consumption while still achieving sufficient communication quality for the active panels.
3Reliability
If all antenna panels are trained to ensure optimal performance, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent segments the antenna panel training process into independent, configurable units. Each antenna panel has its own reference signal resource set that can be independently activated or deactivated. This allows the terminal to train and activate only the specific antenna panels needed for current communication, ensuring reliable performance on active panels while avoiding the power consumption of training and maintaining inactive panels.
Solution Approach 2:
The patent enables the terminal to discard (deactivate) training for antenna panels that are not currently needed for communication. The network device can configure reference signal resource sets selectively, allowing the terminal to focus training resources on active panels and discard training for inactive panels. When communication requirements change, previously trained panels can be recovered and reactivated without requiring full re-training of all panels.
