Abstract
A method of generating and applying combining weights to Physical Uplink Shared Channel (PUSCH) symbols for Open Radio Access Network (O-RAN) fronthaul interface between O-RAN radio unit (O-RU) and O-RAN distributed unit (O-DU) includes: calculating, by the O-DU, a codebook; sending, by the O-DU, the codebook to O-RU; generating, by the O-RU, an RU combiner matrix, using the codebook; applying, by the O-RU, the RU combiner matrix to In-phase and Quadrature (IQ) data to generate compressed IQ data; sending, by the O-RU, the compressed IQ data to O-DU; calculating, by the O-DU, a DU combiner matrix from compressed demodulation reference signal (DMRS); and applying, by the O-DU, the DU combiner matrix to data.
