Dynamic MIMO Mode Switching for Wireless Access Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication access nodes face challenges in dynamically adjusting MIMO transmission modes to balance data throughput and capacity based on usage levels, as existing protocols either prioritize throughput by using all antennas with a single carrier or increase capacity by splitting antennas among multiple carriers, leading to suboptimal performance in varying usage scenarios.
Innovation Solution
Implementing a method that dynamically switches between MIMO 4T-1 carrier and MIMO 2T-2 carrier modes in wireless access nodes based on usage levels, configuring ports to use 4T mode for high throughput when usage is low and 2T mode for increased capacity when usage exceeds a threshold, allowing for adaptive management of wireless communication resources.

Engineering Contradiction Analysis
1Productivity
If all antennas are used with a single carrier to maximize data throughput, then data throughput is improved, but capacity is reduced
Solution Approach 1:
The patent implements dynamic switching between MIMO transmit modes (single carrier with all antennas, or multiple carriers with split antennas) based on real-time access node usage levels. This allows the system to adaptively transition between maximizing throughput and maximizing capacity depending on current network conditions, resolving the static contradiction between these two performance metrics.
2Quantity of substance
If antennas are split among multiple carriers to increase capacity, then capacity is improved, but data throughput is reduced
Solution Approach 1:
The system dynamically adjusts the MIMO transmit mode based on access node usage level thresholds. When usage exceeds the threshold, the system switches to multi-carrier mode with split antennas to maximize capacity. When usage is below the threshold, it switches to single-carrier mode with all antennas to maximize throughput, thereby resolving the contradiction adaptively.
3Device complexity
If MIMO transmit mode is fixed, then system complexity is reduced, but adaptability to varying usage scenarios is reduced
Solution Approach 1:
The patent introduces dynamic adaptability by implementing usage-level-based switching between different MIMO transmit modes. The system monitors access node usage levels and automatically transitions between single-carrier and multi-carrier configurations, enabling adaptation to varying network conditions without requiring complex manual configuration or prediction mechanisms.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring access node usage levels and using this information to dynamically adjust the MIMO transmit mode. This closed-loop control enables the system to respond to changing network conditions and optimize performance adaptively, resolving the contradiction between fixed complexity and adaptive versatility.

AI summary
Embodiments disclosed herein provide systems and methods for dynamically transferring between multiple-input and multiple-output (MIMO) transmit modes based on a usage level of a wireless access node. In a particular embodiment, a method provides transferring wireless communications to a wireless communication device via a plurality of ports in a wireless access node on a wireless communication network. The method further provides determining an access node usage level for the wireless access node. If the access node usage level satisfies a condition for access node usage, the method provides configuring the plurality of ports to use a MIMO 2 transmit-2 carrier mode for transmitting the wireless communications. If the access node usage level does not satisfy the condition for access node usage, the method provides configuring the plurality of ports to use a MIMO 4 transmit-1 carrier mode for transmitting the wireless communications.
