System and method for performance enhancement in heterogeneous wireless access network employing distributed antenna system

A method for optimizing downlink transmission power of a distributed antenna system, comprising:

• transmitting common downlink signals having a first power level from a first antenna unit and a second antenna unit to User Equipment (UE), wherein the first antenna unit and the second antenna unit are physically separated;
• collecting information describing the downlink signals reported by the UE;
• determining when a downlink transmission power of the first antenna unit and second antenna unit should be updated based on the collected information;
• and,
• transmitting downlink signals having a second power level from the first antenna unit and the second antenna unit.

A distributed antenna system, comprising:

• a distributed antenna system service module providing a downlink signal;
• and
• a first antenna unit and a second antenna unit coupled to said distributed antenna system service module by transmission cables to receive said downlink signal and configured for wirelessly transmitting said downlink signal, wherein the first antenna unit and the second antenna unit are physically separated;
• wherein said distributed antenna system service module is configured for controlling the transmission power levels of the first and second antenna units based on collected information from a plurality of User Equipment (UEs) receiving the downlink signals from the antenna units and transmitting uplink information to the antenna units.
