Network Node, Terminal Device and Methods Therein for Data Transmission using Beamforming - A simplified explanation of the abstract

This abstract first appeared for US patent application 17769473 titled 'Network Node, Terminal Device and Methods Therein for Data Transmission using Beamforming

Simplified Explanation

The abstract of the patent application describes a method in a network node for selecting beams for data transmission to a terminal device. The method involves selecting a number of beams, transmitting Channel State Information-Reference Signal (CSI-RS) to the terminal device using the selected beams, receiving a measurement report from the terminal device containing a Rank Indicator (RI) obtained by measuring the CSI-RS, and transmitting data to the terminal device based on the RI using the selected beams.

  • The method involves selecting a number of beams for data transmission to a terminal device.
  • The selected beams are used to transmit Channel State Information-Reference Signal (CSI-RS) to the terminal device.
  • The terminal device measures the CSI-RS and provides a measurement report containing a Rank Indicator (RI).
  • Based on the RI obtained from the measurement report, data is transmitted to the terminal device using the selected beams.

Potential Applications

  • This technology can be applied in wireless communication networks.
  • It can be used to improve the efficiency and reliability of data transmission to terminal devices.

Problems Solved

  • The method solves the problem of selecting beams for data transmission to a terminal device in a network node.
  • It addresses the challenge of optimizing data transmission based on the measurement report obtained from the terminal device.

Benefits

  • The method allows for the selection of multiple beams for data transmission, improving the overall performance of the network.
  • By using the measurement report and the Rank Indicator, data transmission can be optimized based on the specific conditions of the terminal device.
  • The technology enhances the reliability and efficiency of data transmission in wireless communication networks.


Original Abstract Submitted

The present disclosure provides a method () in a network node. The method () includes: selecting () a number, N, of beams for data transmission to a terminal device, where N is an integer larger than one; transmitting () to the terminal device Channel State Information-Reference Signal, CSI-RS, having N ports using the N beams; receiving () from the terminal device a first measurement report containing a Rank Indicator, RI, obtained by the terminal device measuring the CSI-RS; and transmitting () data to the terminal device based on the RI using the N beams.
