    摘要： A system and method for transmitting and receiving frequency allocation information based on identification information in a frequency overlay system are provided. The method includes transmitting a frame of a first Frequency Allocation (FA) to Mobile Stations (MSs) by inserting control information and identification information of the MSs to which frequency resources are allocated into the first FA frame, and transmitting a second frame indicating a second FA the MSs by inserting the identification information and a resource indication of the first FA into the second FA frame. Thereby, an overhead can be reduced and a frequency resource can be used efficiently.

    摘要： Disclosed is a system and a method of signal transmission/reception by a mobile station in a wireless communication system. The method includes: transmitting a first sub-band preparation indicator, which indicates that the mobile station has been prepared for transmission/reception of a signal through a first sub-band, to a base station through a primary band; transmitting a first sub-band failure indicator to the base station through the primary band upon detecting failure in transmitting the first sub-band preparation indicator; receiving sub-band information on a second sub-band, which is different from the first sub-band, from the BS through the primary band; and acquiring synchronization with the second sub-band, so as to enable transmission/reception of a signal through the second sub-band based on the sub-band information.

    摘要： In a mobile communication system, a serving base station receives, from at least one neighboring base station, beamforming information including information about a frame period in which data is transmitted using frequency band-specific beamforming, determines, based on the received beamforming information, whether a beamforming transmit mode of the at least one neighboring base station is a nulling mode in which null data is transmitted to at least one of mobile terminals included in a cell of the serving base station, determines whether a response signal received from the at least one mobile terminal is generated by an interference signal of the at least one neighboring base station, if the beamforming transmit mode of the at least one neighboring base station is the nulling mode, and determines whether to update a backoff factor value based on a result of the determination.
