FEEDBACK DESIGN FOR NETWORK CODED TRANSMISSIONS IN WIRELESS COMMUNICATION NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17531352 titled 'FEEDBACK DESIGN FOR NETWORK CODED TRANSMISSIONS IN WIRELESS COMMUNICATION NETWORK
Simplified Explanation
The abstract describes a method of wireless communication using network coding to improve the reliability of data transmission between user equipment (UE) devices in a sidelink scenario. Here are the key points:
- Receiving UE device receives an original message from a transmitting UE device.
- A network coding device combines the original message with another original message from a different transmitting UE device to create a network coded (NC) packet.
- The original messages correspond to transport blocks, which are units of data transmission.
- If the first transport block is not successfully decoded, the receiving UE device sends a negative acknowledgment (NACK) to indicate the failure.
- If the second transport block is not successfully decoded, the receiving UE device sends another NACK.
- If the first transport block is successfully decoded, the receiving UE device sends an acknowledgment (ACK) to indicate the success.
Potential applications of this technology:
- Wireless communication systems where multiple UE devices need to exchange data reliably.
- Internet of Things (IoT) networks where devices communicate with each other using sidelink connections.
- Vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication systems that require robust data transmission.
Problems solved by this technology:
- Improves the reliability of data transmission by using network coding to combine multiple original messages into a single packet.
- Enables the receiving UE device to identify and report unsuccessful decoding of transport blocks, allowing for retransmission or error correction.
- Increases the overall efficiency of wireless communication by reducing the number of transmissions needed for successful data exchange.
Benefits of this technology:
- Enhanced reliability: By combining multiple original messages, the network coding technique improves the chances of successful data transmission.
- Reduced latency: The use of NACK and ACK messages allows for quick identification of decoding failures and successes, enabling prompt retransmission or further processing.
- Improved efficiency: The method optimizes the use of wireless resources by minimizing the number of transmissions required for successful data exchange.
Original Abstract Submitted
A method of wireless communication by a receiving sidelink user equipment (UE) includes receiving a first original message from a first transmitting sidelink UE. The method also includes receiving, from a network coding device, a network coded (NC) packet that is coded across the first original message and a second original message from a second transmitting sidelink UE. The first original message corresponds to a first transport block. The second original message corresponds to a second transport block. The method further includes transmitting a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded. The method still further includes transmitting a second NACK in response to the second transport block being unsuccessfully decoded. The method still further includes transmitting a first acknowledgment (ACK) in response to the first transport block being successfully decoded.
