Time division duplex wireless network and associated method using connection modulation groups

A wireless network comprising a base station and a plurality of subscriber stations in wireless, radio frequency (RF), time division duplex (TDD) communication with the base station, the wireless network comprising:

• a set of one or more hardware processors configured to:
• for each of the subscriber stations, establish a plurality of associated connections on a RF communication link between the base station and the subscriber station;
• monitor communication traffic on the connections;
• set for each of the connections a modulation format of the RF communication link from the base station to the associated subscriber station based upon the monitored communication traffic;
• assign each of the connections to at least one of a plurality of modulation groups based on a combination of at least the modulation format for the connection and a beam forming for the connection;
• cause transmission of signals on connections assigned to a first of the plurality of modulation groups in a first group of adjacent TDD slots within a TDD frame;
• and cause transmission of signals on connections assigned to a second of the plurality of modulation groups in a second group of adjacent TDD slots within the TDD frame.
