CONFIGURING MEASUREMENT REFERENCE SIGNALS FOR MIMO - A simplified explanation of the abstract

This abstract first appeared for US patent application 18242454 titled 'CONFIGURING MEASUREMENT REFERENCE SIGNALS FOR MIMO

Simplified Explanation

The patent application describes systems and methods for configuring Channel State Information Reference Signal (CSI-RS) ports in a cellular communications network. The method involves configuring a plurality of CSI-RS ports for a wireless device, such as six, ten, twelve, fourteen, or sixteen ports. The method also includes transmitting CSI-RS on at least a subset of the configured ports. This allows for increased support for antenna ports and two-dimensional antenna arrays.

  • The patent application focuses on 6-port and greater than 8-port CSI-RS configurations.
  • The method involves configuring a plurality of CSI-RS ports for a wireless device.
  • The number of CSI-RS ports can be six, ten, twelve, fourteen, or sixteen, depending on the embodiment.
  • CSI-RS is transmitted on at least a subset of the configured ports.
  • This technology provides support for an increased number of antenna ports.
  • It also enables support for two-dimensional (2D) antenna arrays.

Potential Applications

This technology can be applied in various areas, including:

  • Cellular communications networks
  • Wireless devices with multiple antenna ports
  • Two-dimensional antenna arrays

Problems Solved

This technology addresses the following problems:

  • Limited support for antenna ports in cellular communications networks
  • Inability to support two-dimensional antenna arrays effectively

Benefits

The benefits of this technology include:

  • Increased support for antenna ports, allowing for improved network performance
  • Enhanced support for two-dimensional antenna arrays, enabling better signal reception and transmission


Original Abstract Submitted

Systems and methods relating to 6-port and/or greater than 8-port Channel State Information Reference Signal (CSI-RS) configurations are disclosed. In some embodiments, a method of operation of a radio access node in a cellular communications network comprises configuring a plurality of CSI-RS ports for a wireless device, where the plurality of CSI-RS ports is six CSI-RS ports, ten CSI-RS ports, twelve CSI-RS ports, fourteen CSI-RS ports, or sixteen CSI-RS ports, depending on the embodiment. The method further comprises transmitting CSI-RS on at least a subset of the plurality of CSI-RS ports configured for the wireless device. In this manner, support for, e.g., an increased number of antenna ports and/or support for two-dimensional (2D) antenna arrays is provided.
