Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminals struggle with efficient operation in environments where multiple component carriers are transmitted from different directions, leading to increased measurement times and scheduling restrictions in radio resource management and carrier aggregation due to the inability to independently control multiple receive beams.
Innovation Solution
A terminal capable of independently controlling multiple receive beams, allowing them to be directed to different directions simultaneously for enhanced cell detection, radio link monitoring, and carrier aggregation operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a terminal sequentially switches a single receive beam direction to execute measurement, then the terminal can operate with simple beam control, but measurement time increases and productivity decreases
Solution Approach 1:
The patent divides the receive beam control into multiple independent receive beams (first receive beam and second receive beam), allowing simultaneous operation rather than sequential switching. This segmentation enables parallel measurement processes, reducing total measurement time while maintaining manageable control complexity through structured beam management.
Solution Approach 2:
The patent transitions from single-dimensional sequential beam switching to multi-dimensional parallel beam operation. By controlling multiple receive beams simultaneously in different spatial directions, the system adds a dimensional aspect to beam control, enabling concurrent measurements across different component carriers and improving overall productivity.
2Productivity
If a terminal independently controls multiple receive beams directed to different directions, then cell detection and carrier aggregation efficiency improve, but device complexity increases
Solution Approach 1:
The patent segments the receive beam control function into multiple independent receive beams that can be simultaneously controlled. Each receive beam is managed separately with its own control parameters, allowing the terminal to detect cells in different directions concurrently. This segmentation improves cell detection efficiency while keeping individual beam control manageable through modular architecture.
Solution Approach 2:
The patent implements dynamic receive beam control where the terminal can adaptively adjust the number, direction, and configuration of receive beams based on operational requirements. This dynamic capability allows efficient cell detection by activating multiple beams when needed while reducing complexity by using fewer beams when sufficient, providing flexibility in managing device complexity versus productivity trade-offs.
3Ease of operation
If a terminal sequentially switches receive beam direction for measurement, then scheduling restrictions are minimized, but measurement time and loss of time increase
Solution Approach 1:
The patent segments the measurement process into parallel operations using multiple receive beams. Instead of sequentially switching beams for different component carriers, the terminal simultaneously measures multiple carriers using different receive beams. This segmentation eliminates the time loss associated with sequential switching while maintaining scheduling flexibility through independent beam control.
Solution Approach 2:
The patent enables continuous measurement operations by maintaining multiple receive beams active simultaneously. Rather than interrupting measurements to switch beam directions, the system continues useful measurement actions across multiple beams at the same time, eliminating idle time and reducing total measurement time while preserving scheduling flexibility.
Data Source
AI summary
A UE receives a radio signal via a receive beam. The UE controls the receive beam in a first state or in a second state where control of the receive beam is different from that of the first state. The UE executes received power measurement using a synchronization signal block by simultaneously using a plurality of the receive beams in a case of controlling the receive beam in the second state.
