System and Method for Channel Measurement and Interference Measurement in Wireless Network - A simplified explanation of the abstract
This abstract first appeared for US patent application 18335698 titled 'System and Method for Channel Measurement and Interference Measurement in Wireless Network
Simplified Explanation
The patent application describes a method for a user equipment (UE) to perform channel and interference measurements on specific resources and generate a channel state information (CSI) report to be transmitted to a network.
- The method involves performing a channel measurement on a subset of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement on another subset of NZP CSI-RS resources.
- The interference measurement is based on the assumption that each NZP CSI-RS port in the subset corresponds to an interference transmission layer, and the measurement is done using a set of energy per resource element ratios associated with each NZP CSI-RS resource.
- The method also considers that there may be other interference present on both subsets of resources that is not associated with the interference transmission layers.
Potential applications of this technology:
- Wireless communication systems: The method can be applied in various wireless communication systems, such as cellular networks, to improve the accuracy of channel and interference measurements.
- Interference management: By accurately measuring and reporting interference, the network can optimize its resource allocation and interference mitigation strategies.
Problems solved by this technology:
- Accurate interference measurement: The method allows for precise measurement of interference by considering specific subsets of resources and their associated transmission layers.
- Enhanced channel state information: By combining channel and interference measurements, the generated CSI report provides a more comprehensive view of the wireless channel conditions.
Benefits of this technology:
- Improved network performance: The accurate CSI report enables the network to make better decisions regarding resource allocation, interference management, and overall system optimization.
- Enhanced user experience: By optimizing resource allocation and interference mitigation, the technology can lead to improved signal quality, higher data rates, and better overall user experience in wireless communication systems.
Original Abstract Submitted
An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.
