Abstract: Systems, methods, apparatuses, and computer program products for multi-user (MU) multiple-input multiple-output (MIMO) user pairing selection are provided. One method may include selecting multi-user multiple input multiple output (MU MIMO) candidate beams using deep neural network(s) (DNNs), and selecting paired users based on the selected beams. The deep neural network(s) (DNNs) are trained to maximize multi-user priority metric (MU-PM) or a heuristic of the multi-user priority metric (MU-PM).

Abstract: Systems, methods, apparatuses, and computer program products for enabling multi-beam PRACH. One method may include transmitting a physical random access channel preamble based upon at least two different transmission beams in the same random access channel occasion; and receive a message configured to indicate a preferred transmission beam of the transmission beams used with the physical random access channel preamble.
