Solution Overview
Problem
Existing mmWave communication systems face challenges with signal fading and decreased communication quality due to interference from objects in urban or forest environments, leading to sector outages and reduced service quality.
Innovation Solution
The system implements sector beamset management by receiving and storing sector metrics, including beamset data, at primary-secondary cells and special cells of adjacent sectors. This data is used to adjust beamsets dynamically, changing frequency ranges or beam directions to optimize signal strength and reduce interference.

Engineering Contradiction Analysis
1Speed
If mmWave communication is used to provide high-speed data services, then communication speed and capacity are improved, but signal fading and interference from objects increase, leading to sector outages and decreased communication quality
Solution Approach 1:
The system dynamically adjusts beamset parameters including frequency range, beam direction, and beamforming weights based on real-time sector metrics such as signal strength, interference levels, and channel conditions. This dynamic adaptation allows the system to respond to changing environmental conditions and maintain optimal communication performance.
Solution Approach 2:
The patent changes multiple beamset parameters simultaneously including frequency range (e.g., sub-6 GHz to mmWave bands), beam direction angles (azimuth and elevation), and beamforming weight distributions. These parameter changes enable the system to optimize signal propagation by selecting appropriate frequency bands and directional characteristics based on current network conditions.
2Reliability
If beamsets are adjusted frequently to optimize signal strength, then communication quality is improved, but system complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary actions by storing sector metrics data from adjacent sectors at primary-secondary cells and special cells before actual beamset adjustments are needed. This pre-collection and pre-processing of sector metrics enables faster decision-making and reduces real-time computational complexity when beamset changes are required.
Solution Approach 2:
The system implements feedback mechanisms where sector metrics (signal strength, interference, channel conditions) are continuously monitored and used to adjust beamset parameters. The feedback loop compares current performance with target performance and automatically triggers beamset adjustments only when necessary, reducing unnecessary processing complexity.

AI summary
Methods, media, and systems are provided for improving beamset management and enhancing coverage in a wireless telecommunication network utilizing millimeter wave (mmWave) communications. The wireless telecommunication network can correspond to an urban area, for example. As one example, the technology disclosed herein can reduce dropped call rates within the wireless telecommunication network. In embodiments, sector metrics are received for one or more sectors of the wireless telecommunication network and stored at a primary-secondary cell and a special cell of at least one of the sectors of the wireless telecommunication network. A beamset (or at least one parameter thereof) corresponding to a sector is changed based on the sector metrics stored at the primary-secondary cell and the special cell. The sector metrics include beamset data (e.g., beamset data corresponding to an alpha sector of the one or more sectors of the wireless telecommunication network).
