Method and apparatus for radar sensing in a disaggregated radio access network

A method for radar sensing in a disaggregated radio access network, comprising:

• receiving radio unit data, wherein the radio unit data is beam domain data;
• and
• performing radar sensing processing on the received radio unit data to determine at least one of range, velocity, or direction of at least one target in an environment, wherein the radar sensing processing includes range processing, Doppler processing, two-dimensional range-Doppler periodogram processing, constant false alarm rate (CFAR) detection processing, angular resolution processing, and post processing,
• wherein the radar sensing processing further includes performing decompression processing for converting the beam domain data to antenna domain data, and at least the angular resolution processing and the post processing are performed on the antenna domain data.

A machine-readable medium including code, when executed, to cause a machine to:

• receive radio unit data, wherein the radio unit data is beam domain data;
• and
• perform radar sensing processing on the received radio unit data to determine at least one of range, velocity, or direction of at least one target in an environment, wherein the radar sensing processing includes range processing, Doppler processing, two-dimensional range-Doppler periodogram processing, constant false alarm rate (CFAR) detection processing, angular resolution processing, and post processing,
• wherein the radar sensing processing further includes performing decompression processing for converting the beam domain data to antenna domain data, and at least the angular resolution processing and the post processing are performed on the antenna domain data.
