ADAPTIVE DOPPLER FEEDBACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17542248 titled 'ADAPTIVE DOPPLER FEEDBACK
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It focuses on a user equipment (UE) receiving and measuring a reference signal from a node and transmitting a channel feedback report to the node using a specific resource. The channel feedback report includes a Doppler shift associated with measuring the reference signal.
- The UE receives a reference signal from a node and measures it.
- The UE transmits a channel feedback report to the node using a specific resource.
- The channel feedback report includes a Doppler shift value associated with measuring the reference signal.
- The specific resource used for the channel feedback report may be determined based on a mobility parameter of the UE.
- The UE may also measure a second reference signal from the node and transmit a second channel feedback report using a different resource.
- The second resource used for the second channel feedback report is determined based on the measurement of the first reference signal.
- The second channel feedback report includes a Doppler shift value associated with measuring the second reference signal.
Potential Applications
This technology can be applied in various wireless communication systems, including cellular networks, Wi-Fi networks, and other wireless networks. It can improve the efficiency and reliability of communication between user equipment and nodes.
Problems Solved
1. Efficient channel feedback: The invention provides a method for the UE to transmit channel feedback reports to the node, allowing the node to better understand the channel conditions and optimize the communication parameters accordingly. 2. Doppler shift compensation: By including Doppler shift values in the channel feedback reports, the node can compensate for the Doppler effect caused by the relative motion between the UE and the node, improving the accuracy of communication.
Benefits
1. Improved communication performance: By using specific resources and including Doppler shift values in the channel feedback reports, the communication system can adapt to the changing channel conditions and optimize the transmission parameters, resulting in improved performance. 2. Enhanced mobility support: The invention takes into account the mobility parameter of the UE to determine the appropriate uplink resource for channel feedback, ensuring efficient communication even for mobile devices. 3. Increased reliability: By accurately measuring and reporting the reference signals and Doppler shifts, the system can mitigate the effects of channel fading and Doppler shift, leading to more reliable wireless communication.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive and measure a reference signal received from a node and may transmit, to the node, a channel feedback report using a resource, the channel feedback report including a first Doppler shift associated with measuring the reference signal. In some examples, the uplink resource may be one of a set of uplink resources indicated to the UE, and the uplink resource may be based on a mobility parameter associated with the UE. Additionally or alternatively, the UE may measure a second reference signal received from the node and may transmit, to the node, a second channel feedback report using a second resource, where the second resource is based on measuring the first reference signal and where the second channel feedback report includes a second Doppler shift associated with measuring the second reference signal.
