Hybrid Automatic Repeat Request (ARQ) with Spatial Diversity - A simplified explanation of the abstract
This abstract first appeared for US patent application 17920490 titled 'Hybrid Automatic Repeat Request (ARQ) with Spatial Diversity
Simplified Explanation
The abstract describes a wireless system that includes a controlling node and multiple antenna processing nodes. The controlling node sends commands to the antenna processing nodes to transmit data to a wireless device. The selection of the antenna processing node is based on the signal quality metric of the wireless device. If the data is not successfully decoded by the wireless device, the controlling node sends a command to another antenna processing node to transmit the data.
- The wireless system includes a controlling node and multiple antenna processing nodes.
- The controlling node sends commands to the antenna processing nodes to transmit data to a wireless device.
- The selection of the antenna processing node is based on the signal quality metric of the wireless device.
- If the data is not successfully decoded by the wireless device, the controlling node switches to another antenna processing node to transmit the data.
Potential Applications
- Wireless communication systems
- Mobile networks
- Internet of Things (IoT) devices
Problems Solved
- Improves data transmission to wireless devices by selecting the antenna processing node with the best signal quality metric.
- Addresses the issue of unsuccessful data decoding by switching to another antenna processing node.
Benefits
- Enhanced data transmission reliability and quality for wireless devices.
- Improved overall performance of wireless systems.
- Increased efficiency and effectiveness of wireless communication.
Original Abstract Submitted
A wireless system comprises a controlling node and two or more antenna processing nodes coupled to the controlling node but separated from each other. The controlling node sends () a command to a first one of the two or more antenna processing nodes, instructing the first one of the two or more antenna processing nodes to transmit data to a wireless device. This may be preceded by selecting () the first one of the antenna processing nodes based on an estimated signal quality metric corresponding to the wireless device for each antenna processing node. In response to a determination by the controlling node that the wireless device has not successfully decoded the data, the controlling node sends () a command to a second one of the two or more antenna processing nodes, instructing the second one of the antenna processing nodes to transmit the data to the wireless device.
