First Claim
1. A distributed communications system (DCS), comprising:
- a plurality of remote units;
a central unit comprising a routing configuration assigning received one or more downlink communications signals to one or more downlink physical layers among a plurality of downlink physical layers each coupled to a dedicated remote unit among the plurality of remote units;
the central unit configured to;
distribute the received one or more downlink communications signals to the plurality of downlink physical layers each dedicated to a remote unit among the plurality of remote units according to the routing configuration; and
distribute received one or more uplink communications signals from the plurality of remote units over a plurality of uplink optical physical layers each dedicated to a remote unit among the plurality of remote units;
the plurality of remote units each coupled to a downlink physical layer among the plurality of downlink physical layers and an uplink optical physical layer among the plurality of uplink optical physical layers, each remote unit among the plurality of remote units comprising at least one antenna and configured to;
distribute received uplink communications signals received over the at least one antenna over a coupled uplink optical physical layer among the plurality of uplink optical physical layers to the central unit; and
distribute received downlink communications signals from a coupled downlink physical layer among the plurality of downlink physical layers through the at least one antenna; and
the central unit further configured to configure the routing configuration to assign a first multiple-input, multiple-output (MIMO) communications signal among the received one or more downlink communications signals for a first MIMO communications service to a first remote unit among the plurality of remote units having a first remote coverage area.

Abstract
Distributed communications systems (DCSs) supporting configuring or reconfiguring the distribution of MIMO communications streams to designated remote units in the DCS to provide interleaved MIMO cell bonding of remote units are disclosed. In one example, the DCS includes different physical layers that are maintained from the central unit to the remote units. In this manner, the central unit can be configured or reconfigured to distribute separate MIMO communications streams to the desired physical layers in the DCS to support distributing MIMO communications streams to the desired remote units to provide the desired interleaved MIMO communications services. In this manner, interleaved MIMO communications services can be configured for a DCS using an existing infrastructure of remote units having substantially non-overlapping remote coverage areas, by directing the MIMO communications streams over the configured physical layers to be provided to the desired remote units to facilitate interleaved MIMO cell bonding of remote units.
