Abstract: Embodiments of the present invention relate to the field of communications, and provide apparatus which can improve performance of power control on a user who accesses a signal processing entity not supporting a real-time power control function. The apparatus includes: receiving a first signal sent by a first user who accesses a signal processing entity not supporting the real-time power control function; receiving an instruction which is for processing a control channel signal and is sent by a control apparatus, and setting up a channel for bearing the control channel signal of the first signal; and processing the control channel signal which is of the first signal and is borne by the channel, and generating a detection result of the control channel signal which is of the first signal and is borne by the channel. The embodiments of the present invention are applied for real-time power control on the user.

Abstract: Embodiments of the present invention relate to an interference cancellation method and system. The interference cancellation system of the present invention includes a centralized cancellation unit and at least two signal processing units, where at least a part of signal processing units in the at least two signal processing units are configured to detect at least a part of user signals in all user signals input into the interference cancellation system and reconstruct the detected user signals; the centralized cancellation unit is configured to perform cancellation on reconstructed signals and the user signals input into the interference cancellation system; and the at least two signal processing units are configured to detect, according to a residual signal after the cancellation, the user signals input into the interference cancellation system and output the detected signals.
