Wireless communications systems supporting carrier aggregation and selective distributed routing of secondary cell component carriers for selectively directing capacity

A distributed wireless communications system, comprising:

• a signal router circuit, comprising:
• a plurality of signal source inputs each configured to receive a component carrier among a plurality of component carriers, the plurality of component carriers comprising a primary cell component carrier, a first secondary cell component carrier, and a second secondary cell component carrier;
• a plurality of signal outputs each configured to couple to a remote unit among a plurality of remote units;
• and
• a routing control input configured to receive a routing control signal indicating a routing configuration for routing the primary cell component carrier, the first secondary cell component carrier, and the second secondary cell component carrier to the plurality of signal outputs;
• and
• a controller circuit comprising a routing control output coupled to the routing control input, the controller circuit configured to communicate the routing control signal indicating the routing configuration for:
• routing the primary cell component carrier to each of the plurality of signal outputs;
• routing the first secondary cell component carrier to a first subset of the plurality of signal outputs less than all of the plurality of signal outputs;
• and
• routing the second secondary cell component carrier to a second subset of the plurality of signal outputs less than all of the plurality of signal outputs;
• wherein the first subset of the plurality of signal outputs includes at least one signal output not included in the second subset of the plurality of signal outputs.
