摘要： An initial access method of a user equipment (UE) and an apparatus performing the same are provided. The initial access method of a user equipment attempting access a macro cell base station in a network with which the macro cell base station and at least one Femto cell base station share, includes: receiving a cell ID from the macro cell base station or the Femto cell base station; transmitting an interference control request message to the Femto call base station when the received cell ID is a Femto cell ID; and receiving a macro cell ID provided from the macro cell base station when an interference control response message is received from the Femto cell base station to attempt an initial access. When a macro UE near to a Femto cell base station attempts to access a macro cell, it searches an ID of the macro cell through interference control from the Femto call base station to achieve initial access.

摘要： A channel estimation method in a wireless communication system based on multicarrier-code division multiple access (MC-CDMA) using frequency interleaving. A transmitter generates transmission symbols using a pilot signal (P) and an inverted pilot signal (−P) according to subcarriers on which spread symbols generated from a spectrum spreading operation are sent, performs an interleaving operation for the transmission symbols in a frequency domain, and transmits a result of the interleaving operation. A receiver extracts the pilot signal (P) and inverted pilot signal (−P) included in the transmission symbols and performs channel estimation.
