Load Control in Uplink Interference Cancellation Systems With Soft Decision

A base station for load control in uplink interference cancellation systems with soft decision, comprising:

• a processor;
• memory in electronic communication with the processor;
• instructions stored in the memory, the instructions being executable by the processor to:
• determine whether interference is to be cancelled from a received signal based on a packet size of the received signal, and
• if the signal is to be cancelled:
• determine a maximal correlation factor between an interfering portion and a useful portion of the received signal based on a transport block size of the received signal;
• determine a reduced target load for the base station based on the maximal correlation factor;
• and
• adjust uplink transmit power for one or more wireless communication devices based on the reduced target load.
