REFERENCE SIGNAL PORT MAPPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18270058 titled 'REFERENCE SIGNAL PORT MAPPING

Simplified Explanation

The patent application describes a method for reducing the number of beams required per symbol in a wireless communication system. The method involves transmitting reference signals, receiving a report from a user equipment (UE) identifying a matrix, and using the identified matrix to transmit data to the UE or schedule the UE.

  • The method is performed by a base station (gNB).
  • The identified matrix is denoted by (I) and Wps is a port selection matrix, while (II) denotes the Kronecker product.

Potential Applications

This technology can be applied in:

  • 5G and beyond wireless communication systems.
  • Beamforming and massive MIMO systems.

Problems Solved

Original Abstract Submitted

A method for reducing the number of beams required per symbol. The method is performed by a base station (gNB). The method includes transmitting reference signals (RSs) and receiving a report from a UE (302), the report identifying a matrix. The method also includes using the identified matrix to transmit data to the UE or schedule the UE. The matrix identified by the UE is equal to (I) and Wps is a port selection matrix and (II) denotes the Kronecker product.
