Hybrid intra-cell/inter-cell remote unit antenna bonding in multiple-input, multiple-output (MIMO) distributed antenna systems (DASs), and related components, systems, and methods. The MIMO DASs are capable of supporting distributed MIMO communications with client devices. To provide enhanced MIMO coverage areas, hybrid intra-cell/inter-cell remote unit antenna bonding is employed. For example, if a client device has acceptable MIMO communications signal quality with MIMO antennas within a single remote unit, intra-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications, which may avoid power imbalance issues that would result with inter-cell bonded MIMO antennas. However, if a client device has acceptable MIMO communications signal quality with MIMO antennas in a separate, neighboring remote unit(s), inter-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications.
