CSI-RS Resource Reuse for Different Antenna Ports - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056147 titled 'CSI-RS Resource Reuse for Different Antenna Ports

Simplified Explanation

The abstract describes a method for computing channel state information (CSI) using overlapping n-port and m-port CSI-RS resource definitions on a wireless device.

  • The method involves obtaining an overlapping n-port CSI-RS resource definition that overlaps with an m-port CSI-RS resource definition.
  • The number of ports associated with the overlapping n-port CSI-RS resource definition is less than the number of ports associated with the m-port CSI-RS resource definition.
  • The wireless device calculates n-port CSI based on the overlapping n-port CSI-RS definition and reports it to a network node.

Potential Applications

  • Wireless communication systems
  • 5G and beyond networks
  • Internet of Things (IoT) devices

Problems Solved

  • Efficient computation of channel state information
  • Improved wireless communication performance
  • Enhanced network optimization

Benefits

  • Reduced complexity in computing CSI
  • Enhanced network reliability
  • Improved spectral efficiency


Original Abstract Submitted

a method by a wireless device for computing channel state information (csi) includes obtaining an overlapping n-port csi-rs resource definition that overlaps with an m-port csi-rs resource definition. a number n of ports associated with the overlapping n-port csi-rs resource definition is less than a number m of ports associated with the m-port csi-rs resource definition. the wireless device calculates n-port csi based on the overlapping n-port csi-rs definition and reports the n-port csi to a network node.
