PRACH PROCESSING FOR O-RU - A simplified explanation of the abstract

This abstract first appeared for US patent application 18335931 titled 'PRACH PROCESSING FOR O-RU

The abstract describes a patent application where an O-RU (Open RAN Unit) can receive a PRACH (Physical Random Access Channel) preamble and a PUSCH (Physical Uplink Shared Channel) within a slot, with different numerology for each.

  • The O-RU filters a PUSCH cyclic prefix for each symbol of the PRACH preamble using a FFT (Fast Fourier Transform) window per symbol of the PRACH preamble.
  • The FFT window extends from the end of the PRACH preamble.

Potential Applications:

  • This technology can be used in wireless communication systems to efficiently handle different types of uplink channels within the same slot.
  • It can improve the overall performance and spectral efficiency of Open RAN networks.

Problems Solved:

  • Efficient handling of different numerologies for PRACH and PUSCH channels.
  • Optimized filtering of PUSCH cyclic prefix for PRACH preamble symbols.

Benefits:

  • Enhanced spectral efficiency in Open RAN networks.
  • Improved uplink channel management for better overall system performance.

Commercial Applications:

  • This technology can be implemented in 5G and future wireless networks to enhance uplink channel processing and improve network efficiency.

Questions about the Technology: 1. How does the use of different numerologies for PRACH and PUSCH channels impact overall system performance? 2. What are the potential challenges in implementing this technology in existing wireless communication systems?

Frequently Updated Research: There may be ongoing research in the field of Open RAN networks and efficient uplink channel processing that could be relevant to this technology.


Original Abstract Submitted

An O-RU may receive a PRACH preamble and a PUSCH within a plurality of symbols of a slot, the PRACH and the PUSCH having different numerology. The O-RU may filter a PUSCH CP for each symbol of the PRACH preamble through a FFT window per symbol of the PRACH preamble, the FFT window extending from the end of the
