Selective distribution and/or reception of wireless communications signals in a non-contiguous wireless distributed communications system (WDCS) for reducing downlink transmission power and/or uplink noise

A selective router circuit for selectively routing downlink communications signals in a wireless distributed communications system (WDCS), the selective router circuit comprising:

• a router circuit;
• and
• a controller circuit
• wherein the router circuit is configured to:
• receive a cell downlink communications signal comprising a plurality of subcarrier sets transmitted by a cell radio, each subcarrier set among the plurality of subcarrier sets comprising one or more subcarriers, each subcarrier set assigned to a user equipment (UE) among a plurality of UEs;
• and
• wherein the controller circuit is configured to:
• receive a subcarrier assignment indicator indicating the assignment of one or more subcarrier sets among the plurality of subcarrier sets to each UE among the plurality of UEs;
• determine an assignment of one or more UEs to a remote unit among a plurality of non-contiguous remote units in a remote unit cluster in a WDCS;
• determine which of the one or more subcarrier sets among the plurality of subcarrier sets are assigned to which remote unit among the plurality of non-contiguous remote units in the remote unit cluster, based on the determined assignment of the one or more UEs to the remote unit among the plurality of non-contiguous remote units and the subcarrier assignment indicator;
• and
• communicate to the router circuit the remote unit assignment indicator indicating the assignment of the one or more subcarrier sets among the plurality of subcarrier sets to each remote unit among the plurality of non-contiguous remote units in the remote unit cluster;
• wherein the router circuit uses information in the received remote unit assignment indicator to selectively distribute to each remote unit among the plurality of non-contiguous remote units in the remote unit cluster the one or more subcarrier sets assigned to the remote unit.
