CONSTITUTION: A macro BS(Base Station)(810) broadcasts interference tolerance of a femto cell unit(a). A femto BS(820) allocates power to a terminal in consideration of path loss. The femto BS measures channel activity according to a femto cell group of a cluster unit. The macro BS changes the interference tolerance in order to meet a QoS(Quality of Service) of femto cell power allocation.

    Abstract: PURPOSE: A random access channel transmission method in a wireless communication system are provided to selectively perform a random channel transmission by considering channel state of reversed direction in a remote node of the wireless communication system. CONSTITUTION: A remote node measures power of a forward signal of a host node if a forward signal is received(301,303). The remote node checks a reference value for determining transmission of a random access channel(305). The remote node compares the power of the measured forward signal and the checked reference value(307). If the power of a forward signal is bigger than the reference value, the remote node transmits a signal through a reverse RACH(Random Access Channel)(309).

    Abstract: A cell searching method in a communication system and a device are provided to transmit a cell number safely through the second synchronous channel after obtaining frame synchronization by the first synchronous channel by using an error correction code or repeatedly sending cell information, thereby variably controlling a time taken through the second synchronous channel according to channel situations. Slot timing and frame timing are detected by using the first synchronous channel. An ID of a cell to which a terminal belongs or a group ID of the cell is detected by using the second synchronous channel. The slot timing is detected from a synchronous code which constitutes the first synchronous channel. One code sequence is estimated among N code sequences according to the number of synchronous slots of the first predetermined synchronous channel, and the frame timing is detected from the estimated code.
