The open radio access network (O-RAN) concept is changing the landscape of mobile networks (5G deployment and 6G research). O-RAN Alliance's suggestions that O-RAN can offer openness and intelligence to traditional RAN vendors will enable the multi-vendors capability to reshape the RAN structure and optimize the network. One of the main challenges of the O-RAN approach is beamforming implementation. From this point, this seminar will discuss the beamforming methods in O-RAN, address challenges and potential solutions, and suggest the introduction of zero-forcing as a precoding vector in the channel-information-based beamforming method. This may be one of the solutions for achieving flexibility in a high-traffic communication environment while reducing the radio unit interferences caused by implanting the precoding in the open radio unit.
