Multiuser detection for high capacity cellular downlink

A base station comprising:

• a transmitter broadcasting a downlink signal containing user signals intended for a plurality of user devices, the transmitter including transmitting power stacking information in the downlink signal, the power stacking information including a power level for each of the user signals in the transmitted downlink signal.

A mobile device comprising:

• a radio frequency (RF) receiver receiving a downlink transmission containing a user signal intended for the mobile device and one or more interfering user signals directed to one or more other user devices;
• and
• a processor programmed to obtain power stacking information including a power level for each of the user signals contained in the downlink transmission, to estimate a channel using pilot signals in the downlink transmission, to demodulate and decode each interfering user signal contained in the downlink transmission using the power stacking information, and to remove all interfering user signals from the received downlink transmission to obtain the user signal intended for the user device.
