Initial access method and apparatus of user equipment using power reduction request in heterogeneous network

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.

1. An 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, comprising:
receiving a cell ID from the macro cell base station or the Femto cell base station; transmitting an interference control request message for a power reduction of the Femto cell base station to the Femto cell 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.
