A node may forward, from a base station to a first UE, or from the first UE to the base station, one or more wireless signals. The node may identify an indication to stop signal forwarding to the first UE. The indication may be based on a level of an interference to a second UE associated with the signal forwarding to the first UE being greater than a first threshold. The level of the interference to the second UE may be based on a path gain difference or a signal strength at the first UE associated with the signal forwarding to the first UE. The signal strength at the first UE associated with the signal forwarding to the first UE may correspond to an RSRP at the first UE. The node may stop the signal forwarding to the first UE based on the indication.

The method comprises: a network side device confirming the value of an interference parameter of a target cell (201); on the basis of the value of the interference parameter of the target cell, the network side device confirming whether or not the target cell is capable of conducting autonomously the uplink-downlink configuration (202). Employment of the present invention allows for the normal operation of a dynamic uplink-downlink configuration, reduced interference between adjacent cells in a dynamic uplink-downlink configuration environment, and improved system efficiency.

The present invention discloses a power control apparatus and method in a wireless communication system. According to the present invention, among FUE units neighboring to an MUE unit of a victim cell, an FUE unit of an aggressor cell may be derived on the basis of information on RSRP of the FUE unit registered in a closed subscriber group, and a threshold interference value of the FUE unit. Also, power of the derived FUE unit of the aggressor cell may be gradually decreased until an interference of the MUE unit of the victim cell becomes greater than a predefined threshold interference value, and an SINR of the FUE unit of the aggressor cell becomes equal to or greater than a target SINR. Accordingly, CCI can be reduced in a heterogeneous network environment, data transmission speed can be improved, and latency time can be reduced by reducing feedback time.

A frequency mask trigger capable of triggering based on a logical combination of two or more areas of a frequency mask transforms a frame of digital data representing an input signal into a frequency spectrum having a plurality of frequency bins, with each frequency bin having a power amplitude value. A frequency mask is defined having a plurality of reference power levels, one reference power level being associated with each frequency bin. Two or more areas of the frequency mask are defined, with each mask area corresponding to one or more of the frequency bins. A violation status is determined for each mask area by comparing all of the power amplitude values within each mask area to the associated reference power level. If any of the power amplitude values within the mask area violates the associated reference power level, then the entire mask area is deemed to be violated. A trigger signal is generated when a logical combination of the violation statuses of the mask areas is satisfied.
