Solution Overview
Problem
Current beam management methods in 5G wireless technology are inadequate for scenarios where user devices undergo changes in direction or location, leading to inefficiencies in selecting optimal transmit and receive beams, particularly in high mobility situations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If standard beam selection protocol transmissions are used, then beam selection can be performed according to established procedures, but the speed and accuracy of beam selection deteriorates in high mobility scenarios
Solution Approach 1:
The mobile device performs receive beam measurements during measurement gaps before data transmissions occur. By pre-measuring signal quality of candidate receive beams during available gaps in the transmission schedule, the device prepares beam selection information in advance, enabling faster and more accurate beam selection when data transmissions occur, thus resolving the contradiction between speed and accuracy in high mobility scenarios
Solution Approach 2:
The mobile device autonomously identifies measurement gaps in its own transmission schedule and independently performs receive beam measurements during these self-determined gaps without requiring external coordination. This self-service approach allows the device to maintain accurate beam tracking in high mobility conditions while operating within standard protocol frameworks
2Measurement precision
If beam selection protocol transmissions occur frequently, then beam selection accuracy improves, but loss of time for data transmissions increases
Solution Approach 1:
The patent extracts beam measurement activities from the data transmission timeline by utilizing measurement gaps - specific time intervals where data transmissions are suspended. This separation allows beam measurements to be performed without interfering with data transmission continuity, achieving accurate beam measurements while minimizing time loss by confining measurements to predetermined gaps rather than frequently interrupting data flow
Solution Approach 2:
Beam measurements are performed periodically during scheduled measurement gaps rather than continuously or on-demand. This periodic approach ensures beam selection accuracy is maintained through regular updates while minimizing time loss by limiting measurements to specific periodic intervals rather than continuously interrupting data transmissions
