JOINT PRECODING ACROSS MULTIPLE BEAMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17758488 titled 'JOINT PRECODING ACROSS MULTIPLE BEAMS

Simplified Explanation

The patent application describes an innovative method for wireless communication. Here are the key points:

  • The method involves determining the configuration of reference signal (RS) resources to be used by a user-equipment (UE) for beam measurements.
  • The UE is then provided with an indication of the RS resource configuration.
  • The UE performs beam measurements and sends a report to the base station (BS) indicating multiple RS resource indicators based on the measurements.
  • The BS selects a subset of the RS resources based on the UE's report.
  • The BS instructs the UE to provide channel measurement information for the selected subset of RS resources.
  • The UE sends a report to the BS including the channel measurement information.
  • The BS performs joint precoding of signals for transmission using the RS resources based on the channel measurement information.

Potential applications of this technology:

  • Wireless communication systems that require efficient beam measurements and channel measurement information.
  • 5G and future wireless networks that rely on beamforming and precoding techniques.

Problems solved by this technology:

  • Simplifies the process of determining RS resource configuration for beam measurements.
  • Enables efficient selection of RS resources based on UE reports.
  • Facilitates joint precoding of signals based on channel measurement information.

Benefits of this technology:

  • Improved wireless communication performance through optimized beam measurements and precoding.
  • Enhanced efficiency in utilizing RS resources.
  • Simplified implementation of beamforming and precoding techniques in wireless networks.


Original Abstract Submitted

One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.
