Dynamic Air Interface Selection for Adaptive Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE systems, air interface technologies use fixed manners for communication, which limits adaptability to varying communication scenarios, whereas 5G systems offer multiple optional manners, necessitating a method to dynamically select the most appropriate air interface technology for actual communication conditions.
Innovation Solution
A communication method where a terminal device determines a target air interface technology manner by receiving a notification message from a network device, allowing flexible adaptation to different communication scenarios by selecting from various optional manners such as random access, uplink waveform, multiple access, modulation scheme, or duplexing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed air interface technology manners are used (as in LTE), then system simplicity and ease of operation are maintained, but adaptability to different communication scenarios deteriorates
Solution Approach 1:
The patent implements dynamic selection of air interface technology manners by introducing multiple optional configurations (first, second, and third manners) that can be adaptively chosen based on communication scenarios. The network device determines the appropriate manner and notifies the terminal device, enabling the system to transition from static fixed configurations to dynamic adaptive selections, thereby improving adaptability while managing complexity through centralized control.
2Adaptability or versatility
If multiple optional air interface technology manners are provided (as in 5G), then adaptability to different scenarios is improved, but system complexity and difficulty of operation increase
Solution Approach 1:
The patent enables the network device to autonomously determine the most appropriate air interface technology manner based on network conditions and requirements, eliminating the need for terminal devices to make complex selection decisions. The network device performs the selection function and notifies terminal devices of the chosen manner, allowing the system to self-manage the complexity of multiple optional configurations while maintaining ease of operation for terminal devices.
3Productivity
If dynamic selection of air interface technology is implemented, then communication efficiency is improved, but information exchange overhead increases
Solution Approach 1:
The patent reduces information overhead by performing preliminary determination of the air interface technology manner before actual communication begins. The network device determines the appropriate manner in advance and notifies terminal devices prior to data transmission, allowing terminal devices to pre-configure their communication parameters. This preliminary action eliminates the need for continuous negotiation and reduces signaling overhead during ongoing communication.
Data Source
AI summary
A communication method is described that includes a terminal device receiving a first message sent by a network device to which the terminal device expects to be handed over, and the first message indicates at least one target manner of the air interface technology determined by the network device from at least one optional manner of the air interface technology. Thereafter, the terminal device communicates with the network device by using the at least one target manner of the air interface technology.
