Preamble Beam Selection Using Contention-Free Resource Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, selecting an appropriate beam for preamble transmission is challenging, as multiple beams may be available, but the most suitable beam is often not selected for transmission.
Innovation Solution
A processor determines a beam for preamble transmission by prioritizing beams configured with contention-free resources or selecting beams with the best channel quality, ensuring efficient and reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beams are available for preamble transmission, then the system provides more transmission options and flexibility, but the difficulty of selecting the optimal beam increases and reliability decreases
Solution Approach 1:
The patent changes the parameter of beam selection by introducing a priority value associated with each beam. Instead of randomly selecting or manually choosing a beam, the system assigns priority values to beams and automatically selects the beam with the highest priority for preamble transmission. This parameter-based selection mechanism resolves the contradiction by providing systematic adaptability while ensuring reliable transmission through priority-driven beam choice.
Solution Approach 2:
The patent applies local quality by associating different priority values with different beams based on their specific characteristics and configurations. Each beam is evaluated individually and assigned a priority value reflecting its suitability for preamble transmission. This allows the system to optimize beam selection locally for each beam's specific properties while maintaining overall system reliability.
2Ease of operation
If a beam is selected without considering contention-free resources, then the selection process is simpler, but communication efficiency and reliability deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority values for beams based on their contention-free resource status and other characteristics before actual preamble transmission occurs. The base station prepares beam priority information in advance and provides it to the remote unit, so that when beam selection is needed, the remote unit can efficiently select the optimal beam using the pre-established priority values without complex real-time analysis.
3Device complexity
If the most suitable beam is not selected from multiple available beams, then the system operation is simpler, but communication reliability and performance worsen
Solution Approach 1:
The patent implements feedback by having the base station evaluate beam conditions and assign priority values based on current network state, beam quality metrics, and contention-free resource availability. The base station provides this priority information back to the remote unit, enabling the remote unit to make informed beam selection decisions. This feedback mechanism ensures that the most suitable beam is selected while keeping the remote unit's selection logic simple.

AI summary
Apparatuses, methods, and systems are disclosed for determining a beam for preamble transmission. One apparatus (200) includes a processor (202) that determines (702) a beam from multiple beams for preamble transmission. In response to the multiple beams including one or more beams configured with a contention-free resource, the one or more beams configured with a contention-free resource have a higher priority than other beams of the multiple beams.
