BASEBAND UNIT, RADIO UNIT AND METHODS IN A WIRELESS COMMUNICATIONS NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195472 titled 'BASEBAND UNIT, RADIO UNIT AND METHODS IN A WIRELESS COMMUNICATIONS NETWORK

The abstract describes a method for assisting a radio unit in performing beamforming for communication in a wireless network using a multiple antenna system.

  • The baseband unit (BBU) calculates beamforming weights (BFWs) for a subset of subcarriers.
  • The BBU transforms the calculated BFWs from frequency domain to tap-domain BFWs using a mathematical transformation.
  • One or more tap-domain BFWs are selected and sent to the radio unit (RU) to assist in beamforming.
  • The selected tap-domain BFWs help the RU in optimizing communication between the user equipment (UE) and the base station.

Potential Applications: - Wireless communication networks - 5G technology - Mobile telecommunications

Problems Solved: - Enhancing communication efficiency - Improving signal quality - Optimizing beamforming processes

Benefits: - Increased data transmission rates - Enhanced network performance - Better user experience in wireless communication

Commercial Applications: Title: "Advanced Beamforming Technology for Wireless Networks" This technology can be utilized in telecommunications companies, network equipment manufacturers, and providers of wireless services to improve network performance and user experience.

Prior Art: Further research can be conducted in academic journals, patent databases, and industry publications to explore prior art related to beamforming technologies in wireless communication networks.

Frequently Updated Research: Stay informed about the latest advancements in beamforming technology, wireless communication standards, and antenna systems to ensure the implementation of cutting-edge solutions in network optimization.

Original Abstract Submitted

a method is provided, performed by a baseband unit (bbu) for assisting a radio unit (ru) to perform beamforming for a communication between a user equipment (ue) and a base station in a wireless communications network using a multiple antenna system for communication. the bbu and the ru are associated with the base station. the bbu calculates () respective beamforming weights. bfws, for at least a subset of subcarriers out of a number of subcarriers. the bbu transforms () by a mathematical transformation, the respective calculated bfws, from frequency domain bfws to obtain tap-domain bfws. the bbu select () one or more tap-domain bfws from said obtained tap-domain bfws. the bbu sends () to the ru, the selected one or more the tap-domain bfws. the selected one or more tap-domain bfws assists the ru to perform beamforming for the communication between the ce and the base station.
