3D Beam User Service Mode Selection for Capacity Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2D antenna configurations fail to meet the increasing demands of users in residence communities for communication services, particularly in terms of capacity and quality, as they struggle to efficiently utilize 3D beam forming technologies to serve multiple users simultaneously while maintaining communication quality.
Innovation Solution
A user service mode selection method for 3D beams that compares the number of users to scheduling units, selecting single-user or multi-user service modes based on SNR calculations and channel capacity, employing inner and outer beams for spatial division multiplexing to optimize resource allocation and reduce system busyness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 3D beam forming technology is used to generate two beams (inner beam and outer beam) for serving multiple users simultaneously, then the communication capacity and number of users served increase, but the complexity of resource allocation and user service mode selection increases
Solution Approach 1:
The system dynamically selects between single-user service mode and multi-user service mode based on the ratio of users to scheduling units. When the user count exceeds scheduling unit capacity, the system transitions to multi-user service mode with spatial division multiplexing, otherwise it uses single-user service mode. This dynamic adaptation resolves the contradiction by adjusting system behavior according to real-time conditions.
Solution Approach 2:
The patent changes the service mode parameter (single-user vs. multi-user) based on the user-to-scheduling-unit ratio threshold. By monitoring this parameter and switching modes accordingly, the system optimizes communication capacity while managing allocation complexity through structured mode selection rather than continuous complex optimization.
2Productivity
If multi-user service mode is selected to serve more users with the same time-frequency resource, then system capacity increases, but the calculation complexity for SNR and channel capacity increases
Solution Approach 1:
The system performs preliminary calculations of SNR for inner and outer beams, and channel capacity for user groups before final mode selection. By pre-calculating these parameters and comparing them against thresholds, the system reduces the complexity of real-time decision-making while enabling multi-user service mode when beneficial for system capacity.
Solution Approach 2:
The patent segments users into different user groups based on their characteristics and channel conditions. Each user group is evaluated independently for multi-user service mode suitability, dividing the complex overall optimization problem into smaller, manageable segments that can be assessed separately and combined.
3Adaptability or versatility
If conventional 2D antenna configuration is used, then system complexity is low, but it cannot meet the increasing communication service demands of users in residence communities
Solution Approach 1:
The patent transitions from conventional 2D antenna configuration to 3D beam forming by introducing the vertical dimension through adjustable radiation angles. This creates inner beams and outer beams with different spatial orientations, enabling the system to serve more users simultaneously in residence communities while managing complexity through structured mode selection.

AI summary
A user service mode selection method in the case of 3D beams, a pilot frequency information sending method and apparatus are disclosed. The selection method includes: comparing the total number of the users to be served with that of scheduling units; selecting a single-user service mode for each user when the total number of the users to be served is smaller than that of scheduling units; selecting J user groups meeting a preset condition to adopt a multi-user service mode when the total number of the users to be served is not smaller than that of scheduling unit, J is an integer greater than 1, and 2J is an integer not greater than the total number of the users to be served; one time-frequency resource only corresponds to one beam configured for communication in the single-user service mode but at least two beams in the multi-user service mode.
