Beam Resource Allocation for High-Frequency Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource allocation methods using high-frequency narrow beams in communications systems result in poor user experience and high implementation costs due to long waiting times and inefficient resource distribution, especially when a large number of users are evenly distributed within a coverage area.
Innovation Solution
A communications device and method that acquires beam IDs from user equipment, determines user equipment locations and quantities, selects to-be-connected users, and calculates resource ratios according to a preset policy, allowing for efficient allocation of resources through physical downlink control channel information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If full-range time-division coverage is implemented using a single beam for high-frequency narrow beam communication, then coverage area is improved, but user waiting time increases and user experience deteriorates
Solution Approach 1:
The patent segments the coverage area into multiple spatial regions (S regions and T regions) and assigns different beams to different regions. This allows simultaneous service to multiple users in different regions, eliminating the time-division waiting period while maintaining narrow beam coverage characteristics.
Solution Approach 2:
The patent transitions from time-division multiplexing to space-division multiplexing by introducing spatial dimension (different beams pointing to different spatial regions). This resolves the contradiction by serving multiple users simultaneously in space rather than sequentially in time.
2Device complexity
If resources are allocated in units of timeslots (TTIs) in time domain, then resource allocation simplicity is maintained, but user waiting time increases and resource allocation efficiency decreases
Solution Approach 1:
The patent segments resource allocation from coarse time-division units into finer spatial units (beam-level allocation). Resources are allocated to specific beams and spatial regions rather than entire timeslots, improving efficiency while maintaining manageable complexity through structured allocation rules.
Solution Approach 2:
The patent applies local quality by allocating resources specifically to beams serving particular spatial regions rather than uniformly across all users. This allows optimized resource distribution matching actual user distribution patterns, improving overall system efficiency.
3Quantity of substance
If high-frequency narrow beams are used for communication, then bandwidth resources are improved, but path loss increases and coverage difficulty increases
Solution Approach 1:
The patent applies local quality by concentrating narrow beam energy into focused spatial regions rather than dispersing it broadly. This concentrates the available bandwidth resources into targeted areas, achieving effective coverage despite high path loss characteristics of high-frequency signals.
