A method for identifying a MBSFN (Multimedia Broadcast multicast service Single Frequency Network) subframe at a user equipment (UE) in a wireless communication system is disclosed. Receiving module may receive receiving a subframe type information from an base station (BS). Receiving module may receive type information of the MBSFN subframe. The identifying module may identify an index of a MBSFN subframe based on the received subframe type information. The identifying module may identify a type of the MBSFN subframe based on the received type information of the MBSFN subframe. Decoding module may decode only a physical control channel region of the MBSFN subframe based on the identified type of the MBSFN subframe. Alternatively, Decoding module may decode the MBSFN subframe if the identified type of the MBSFN subframe is a decodable type or a known type.

Provided are a method and an apparatus for releasing a blank zone by a macro base station in a wireless communication system. The macro base station: receives channel information from a macro terminal that is serviced therefrom; determines based on the channel information whether or not a downlink blank zone allocated to a resource zone of a femto bas station is released; and transmits downlink blank zone release information to the femto base station if the downlink blank zone is supposed to be released. The downlink blank zone is a resource zone which restricts the downlink transmission, among all the resource zones used by the femto base station. The channel information may be the information about the distance between the femto base station and the macro terminal.

A method and apparatus for allocating a ranging channel for a synchronized mobile station in a wireless communication system is provided. A base station (BS) allocates the ranging channel for the synchronized mobile station in a first subframe and a first subband. An index of the first subframe and an index of the first subband are determined respectively based on an index of a second subframe and an index of a second subband in which a ranging channel of a non-synchronized mobile station is allocated.

A method for multiplexing one or more multiple access regions is disclosed. The method for multiplexing one or more multiple access regions in a wireless access system comprises multiplexing the one or more multiple access regions so that a first base station and a second base station among a plurality of base stations which use one or more multiple access schemes together under a multi-cell environment use a single multiple access scheme in a predetermined resource region allocated to each of the first base station and the second base station; and transmitting multiplexing information obtained from the multiplexing the one or more multiple access regions to a mobile station included in a cell region of the plurality of base stations. As a user uses SC-FDMA scheme and OFDMA scheme together, it is possible to obtain a single carrier effect of the SC-FDMA system and flexibility of the OFDMA system on a time axis and a frequency axis.

A method of reporting a channel state for a plurality of bands includes transmitting channel quality indicators (CQIs) for the respective bands, and transmitting CQI variation information, wherein the CQI variation information comprises CQI up/down information indicating whether the CQIs of the respective bands collectively increase or decrease and a CQI variation indicating a collective variation of the CQIs of the respective bands. Accordingly, waste of resources consumed for the CQIs can be reduced.
