Solution Overview
Problem
Massive MIMO wireless networks face interference issues due to increased numbers of transmit and receive antennae, leading to compromised throughput and resource inefficiencies.
Innovation Solution
A method and system that monitor interference levels in wireless sectors and adjust the number of operating antennae, reducing the number when interference meets a threshold to mitigate interference, using configurations such as 64T64R, 32T32R, 16T16R, or 8T8R, by activating or deactivating physical or logical antenna ports.

Engineering Contradiction Analysis
1Productivity
If the number of transmit and receive antennae is increased in massive MIMO networks, then the capacity and data stream volume are improved, but the interference level increases and throughput is compromised
Solution Approach 1:
The patent implements dynamic adjustment of the number of active antennae based on real-time interference conditions. The system transitions from static antenna configuration to dynamic reconfiguration, where the access node monitors interference levels and adjusts the number of active antennae accordingly, allowing the system to adapt to changing channel conditions and interference environments.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by adjusting the number of active transmit and receive antennae based on interference thresholds. When interference exceeds a predetermined threshold, the system reduces the number of active antennae, thereby changing the system parameters to mitigate interference while maintaining acceptable network capacity.
2Productivity
If the number of transmit and receive antennae is increased in massive MIMO networks, then more data streams can be transmitted simultaneously, but resource inefficiencies occur when massive MIMO transmission modes are disabled
Solution Approach 1:
The system dynamically adjusts antenna configuration based on real-time interference conditions rather than maintaining a fixed configuration. This allows the network to utilize massive MIMO capabilities when conditions are favorable (high data stream volume) while reducing to conventional MIMO when interference is high, optimizing resource utilization across different operating conditions.
Solution Approach 2:
The patent changes the operational state of the antenna system by switching between different numbers of active antennae based on interference thresholds. This parameter change enables the system to maintain massive MIMO transmission modes when beneficial for data stream volume while avoiding resource waste when interference would compromise performance.
3Object-affected harmful factors
If the number of operating antennae is reduced to mitigate interference, then throughput is improved, but the network capacity and data stream volume decrease
Solution Approach 1:
The system implements dynamic reconfiguration of antenna resources based on real-time interference monitoring. Rather than permanently reducing antenna count, the system temporarily adjusts the number of active antennae in response to interference conditions, allowing full network capacity to be restored when interference conditions improve.
Solution Approach 2:
The patent applies parameter changes by adjusting the number of active antennae as a controllable variable. When interference exceeds thresholds, the system reduces the antenna parameter to mitigate interference; when interference is acceptable, the system increases the antenna parameter to maximize network capacity, creating an optimized operating point that balances both concerns.

AI summary
Systems for mitigating interference in a massive MIMO wireless network include an access node, a plurality of antennae communicatively coupled to the access node, and a processor communicatively coupled to the access node. The processor can be configured to perform operations including communicating with one or more wireless devices within a wireless sector utilizing one or more antennae from the plurality of antennae, and monitoring an interference level within the wireless sector. Upon the interference level meeting a threshold, the processor may be configured to utilize fewer antennae to communicate with the one or more wireless devices. Conversely, upon the interference level not meeting the threshold, the processor may be configured to utilize more antennae to communicate with the one or more wireless devices.
