Beam Scanning Range Determination for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in beam scanning due to the need to scan all beams in a spatial area, leading to increased scanning time and signal transmission delays.
Innovation Solution
A method and device that determine a beam scanning range based on status information of a terminal, including dimensions such as relative position, working status, and posture, using preset rules to influence the scanning range, thereby narrowing the scope of beams to be scanned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal scans all beams in the spatial area, then the beam scanning coverage is complete, but the scanning time increases and scanning efficiency decreases
Solution Approach 1:
The patent extracts only the necessary beams for scanning based on terminal status information. Instead of scanning all beams in the spatial area, the system determines a specific beam scanning range containing only those beams that are relevant to the terminal's current status, thereby reducing scanning time while maintaining coverage of important beams
Solution Approach 2:
The patent applies local quality by making the beam scanning range adaptive to different terminal statuses. The scanning range is customized for each terminal based on its specific status information, allowing different terminals to scan different subsets of beams according to their local conditions rather than using a uniform comprehensive scanning approach
2Measurement precision
If the terminal scans all beams in the spatial area, then the beam selection accuracy is improved, but the signal transmission delay increases
Solution Approach 1:
The patent performs preliminary action by determining the beam scanning range before the actual beam scanning process. The base station or terminal determines which beams should be scanned based on status information, and this predetermined scanning range is then used to guide the scanning process, ensuring that only relevant beams are scanned and reducing overall delay
Solution Approach 2:
The patent applies partial action by scanning only a subset of beams that are most relevant to the terminal status, rather than scanning all beams. The beam scanning range is carefully selected to include sufficient beams for accurate beam selection while excluding unnecessary beams, achieving a balance between accuracy and speed
3Reliability
If the beam scanning range includes all beams, then the completeness of beam measurement is ensured, but the scanning complexity increases
Solution Approach 1:
The patent extracts the essential beams needed for measurement based on terminal status information. By identifying and extracting only the relevant beams from the complete set of spatial beams, the system maintains measurement completeness for important beams while reducing the overall number of beams that need to be scanned and processed
4Device complexity
If the terminal uses a fixed beam scanning range, then the system simplicity is maintained, but the adaptability to terminal status changes is reduced
Solution Approach 1:
The patent implements dynamics by making the beam scanning range adjustable and adaptive to terminal status changes. The system dynamically determines the beam scanning range based on current terminal status information, allowing the scanning configuration to change as terminal conditions change, thereby achieving adaptability without requiring a completely complex reconfiguration system

AI summary
A method for determining a beam scanning range includes acquiring status information of a terminal. The status information includes status data of at least one dimension and the at least one dimension is preset to affect the performance of a radio frequency device of the terminal. A preset rule is acquired. The preset rule includes a respective influence rule of each dimension on a beam scanning range. A beam scanning range is determined based on the status data of the at least one dimension and the preset rule.
