Engineering Contradiction Analysis
1Productivity
If multiple transmission modes are activated in wireless devices with multi-RAT communication and MIMO capabilities, then network capacity and data transmission capability are improved, but interference and power consumption increase, degrading battery life and signal quality
Solution Approach 1:
The patent implements dynamic antenna configuration where the wireless device adapts its antenna settings based on the current transmission type. The device switches between different antenna configurations (e.g., full MIMO mode, reduced antenna mode, single-antenna mode) depending on whether the transmission is control-plane or user-plane, 4G or 5G, thereby dynamically optimizing performance while minimizing interference and power consumption for each specific transmission scenario
2Productivity
If multiple transmission modes are activated in wireless devices with multi-RAT communication and MIMO capabilities, then network capacity and data transmission capability are improved, but power consumption increases, degrading battery life
Solution Approach 1:
The patent applies partial action by activating only the necessary number of antennas based on transmission requirements. Instead of always using all available antennas for MIMO operations, the device uses a reduced set of antennas for control-plane transmissions or when channel conditions don't require full MIMO capability, thereby consuming less power while maintaining adequate network capacity for the specific transmission task
3Reliability
If all antennae are used for all transmission types, then comprehensive signal coverage and capacity are maintained, but unnecessary interference is generated and power is wasted on transmissions that do not require full antenna utilization
Solution Approach 1:
The patent implements local quality by tailoring the antenna configuration to the specific requirements of each transmission type. Control-plane transmissions use a different antenna configuration than user-plane transmissions, and 4G transmissions use different settings than 5G transmissions. This localized optimization ensures that each transmission receives the appropriate level of antenna resources without generating unnecessary interference from over-provisioning

AI summary
Selecting combinations of antennae of a wireless device based on transmission type includes determining a transmission type of a transmission between the wireless device and an access node and, based on the transmission type, instructing the wireless device to utilize different antenna configurations, including 5G EN-DC, MIMO, mm-wave, and other combinations. The different antenna configurations comprise different combinations of antennae of the wireless device.
