Abstract
A method for load control in uplink interference cancellation systems with soft decision is disclosed. It is determined whether interference is to be cancelled from a received signal based on a packet size of the received signal. If the signal is to be cancelled, a maximal correlation factor between an interfering portion and a useful portion of the received signal is determined based on a transport block size of the received signal. If the signal is to be cancelled, a reduced target load for a base station is also determined based on the maximal correlation factor. If the signal is to be cancelled, uplink transmit power for one or more wireless communication devices is adjusted based on the reduced target load.

A method for load control in uplink interference cancellation systems with soft decision, comprising:
- determining 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:
- determining 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;
- determining a reduced target load for a base station based on the maximal correlation factor;
- and
- adjusting uplink transmit power for one or more wireless communication devices based on the reduced target load.
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.
A base station for load control in uplink interference cancellation systems with soft decision, comprising:
- means for determining whether interference is to be cancelled from a received signal based on a packet size of the received signal;
- means for determining, if the signal is to be cancelled, 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;
- means for determining, if the signal is to be cancelled, a reduced target load for the base station based on the maximal correlation factor;
- and
- means for adjusting, if the signal is to be cancelled, uplink transmit power for one or more wireless communication devices based on the reduced target load.
