Terminal Beam Switching via Parameter-Time Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial manufacturing, terminal communication with base stations involves significant communication latency and pilot overhead due to the need for beam scanning, beam management, and beam tracking, which are resource-intensive and time-consuming processes.
Innovation Solution
A communication method that utilizes a mapping relationship between parameter sets and time periods to directly determine optimal beams, eliminating the need for beam scanning and tracking, by configuring control information transmission based on pre-defined parameter sets and time periods, thereby reducing latency and improving communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam scanning, beam management, and beam tracking are performed to determine optimal beam, then communication quality is improved, but communication latency increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a mapping relationship between parameter sets and time periods before actual communication occurs. The terminal device obtains this mapping relationship in advance through configuration information, allowing it to directly determine the parameter set for a given time period without performing time-consuming beam scanning, beam management, or beam tracking operations at the moment of communication, thus reducing latency while maintaining communication quality
Solution Approach 2:
The patent applies dynamics by making the parameter set dynamic based on time periods. The mapping relationship allows different parameter sets to be associated with different time periods, enabling the terminal device to adaptively select appropriate parameters for each time period. This dynamic approach eliminates the need for continuous beam tracking while maintaining optimal communication quality through time-varying parameter selection
2Reliability
If beam scanning, beam management, and beam tracking are performed to determine optimal beam, then communication quality is improved, but pilot overheads increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the mapping relationship between parameter sets and time periods before communication begins. This eliminates the need for extensive pilot signals during beam scanning and beam tracking operations, as the terminal device can directly determine appropriate parameters from the pre-established mapping relationship, thereby reducing pilot overheads while maintaining communication quality
Solution Approach 2:
The patent applies copying by using a pre-defined mapping relationship structure that can be reused across multiple time periods. Instead of performing resource-intensive beam management operations each time, the system copies and applies the appropriate parameter set from the pre-established mapping relationship, significantly reducing the need for pilot overheads

AI summary
A communication method to reduce a communication latency. The method includes: a terminal obtains a mapping relationship, where the mapping relationship includes a mapping relationship between M parameter sets and M time periods, the parameter set includes a value of at least one parameter, and M is an integer greater than or equal to 2. The terminal receives first control information in a first time period based on the mapping relationship, where the first time period is included in the M time periods.
