Abstract: A method for switching transmission methods in a multiple input multiple output (MIMO) system may include: receiving scenario identification related data from a user equipment (UE) in a current transmission method; determining a target transmission method of the UE from at least two predefined transmission methods based on the scenario identification related data; and switching the current transmission method of the UE to the target transmission method.

Abstract: A method and apparatus for supporting a multiple-input multiple-output (MIMO) by a service management and orchestration (SMO) entity in a communication system using an open radio access network (O-RAN) includes receiving, from a first entity, first data, the first entity including at least one of an O-RAN centralized unit (O-CU) and an O-RAN distributed unit (O-DU), the first data including MIMO related information collected from the first entity, determining, based on the first data, a configuration for applying at least one of a single-user-multiple-input-multiple-output (SU-MIMO) and a multi-user-multiple-input-multiple-output (MU-MIMO), and transmitting, to a second entity that controls the first entity in the O-RAN, information on the configuration.
