TECHNIQUES FOR MITIGATING INTER-NETWORK NODE INTERFERENCE IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17816569 titled 'TECHNIQUES FOR MITIGATING INTER-NETWORK NODE INTERFERENCE IN WIRELESS COMMUNICATIONS
Simplified Explanation
The patent application describes techniques for mitigating interference between network nodes operating in full duplex (FD). Here are the key points:
- Victim network nodes can indicate their capability to cancel interference from aggressor network nodes.
- Victim network nodes can receive uplink signals from a device and downlink signals from the aggressor network node simultaneously.
- Based on the indicated capability, the victim network node can cancel the downlink signals received from the aggressor network node using the uplink signals received from the device.
- The victim network node can also indicate specific uplink resources to the aggressor network node, which helps avoid transmitting downlink communications over those resources.
Potential applications of this technology:
- Wireless communication networks: This technology can be applied to improve the performance and efficiency of wireless networks by mitigating interference between network nodes.
- Cellular networks: Full duplex operation can enhance the capacity and throughput of cellular networks, and the techniques described in the patent application can further improve the interference management in such networks.
- Internet of Things (IoT): With the increasing number of IoT devices, interference management becomes crucial. This technology can help IoT devices operate more efficiently in crowded network environments.
Problems solved by this technology:
- Interference mitigation: The techniques described in the patent application help mitigate interference between network nodes operating in full duplex, improving the overall performance and reliability of the network.
- Efficient resource utilization: By indicating specific uplink resources to aggressor network nodes, unnecessary downlink communications over those resources can be avoided, leading to more efficient resource allocation.
Benefits of this technology:
- Improved network performance: Mitigating interference between network nodes enhances the overall performance and reliability of the network, leading to better user experience.
- Increased capacity: Full duplex operation combined with interference mitigation techniques can increase the capacity and throughput of wireless networks.
- Efficient resource allocation: By avoiding unnecessary downlink communications over specific uplink resources, the network can allocate its resources more efficiently, optimizing the utilization of available bandwidth.
Original Abstract Submitted
Aspects described herein relate to mitigating interference between network nodes operating in full duplex (FD). In some aspects, a victim network node can indicate, to an aggressor network node, a capability to cancel interference from the aggressor network node, receive one or more uplink signals from a device along with one or more downlink signals from the aggressor network node in a same time period, and cancel, based on the capability, the one or more downlink signals received from the aggressor network node from the one or more uplink signals received from the device. In other aspects, the victim network node can indicate certain uplink resources to the aggressor network node, which can avoid transmitting downlink communications over the indicated uplink resources.
