Abstract: A distributed unit (DU) includes a processor and a transceiver operatively coupled to the processor. The transceiver is configured to transmit information indicating a plurality of candidate combining methods, and receive a compressed signal. The compressed signal is based on at least one of the candidate combining methods. The transceiver is further configured to receive, from a radio unit (RU), information indicating a combining method supported by the RU, from the plurality of candidate combining methods and transmit information indicating combining weights for the candidate combining method.

Abstract: For an O-RAN system, supported hybrid beamforming configurations are indicated based on a number of analog ports, a number of digital ports, a number of analog ports per transceiver, and supported codebooks. A hybrid beamforming configuration to be employed includes control bit vectors for phase-shifters, each control bit vector mapped to a phase value, an in-phase (I) value and a quadrature (Q) value. The hybrid beamforming configuration may include analog and digital beamforming parameters applicable to frequency bands or subbands or joint phase-time array parameters.
