    Abstract: An uplink capacity is increased by a method in which more than two mobile stations simultaneously use a radio resource allocated to one mobile station. A method of allocating a radio resource in an orthogonal frequency division multiplexing system comprises receiving data associated with a radio resource allocation map from a base station, wherein the radio allocation map comprises control parameters for transmitting uplink data to the base station. The control parameters comprises orthogonal pilot pattern indicator for using orthogonal pilot patterns associated with supporting at least concurrent dual transmission by at least one mobile station, and for use in the same frequency band and same time duration. The orthogonal pilot patterns comprises at least a minus pilot being used for an uplink basic allocation unit. The mobile station then transmits uplink data to the base station by using the orthogonal pilot patterns.

    Abstract: A method of performing a handover in a wireless communication system employing a macro base station and a femto base station is provided. The method comprising: monitoring an uplink signal transmitted from a user equipment to the macro base station; transmitting a handover initiation message to the macro base station on the basis of a result of comparing the uplink signal's strength obtained by the monitoring with a reference value; and performing a handover of the user equipment from the macro base station to the femto base station. According to the present invention, there is provided a method of initiating a handover by a femto base station by fining user equipments located in a cell coverage of the femto base station. In addition, a signaling overhead is reduced by utilizing previously existing information such as uplink transmit power.
