Abstract: A method of determining member Base Stations (BSs) providing cooperative communication to a Mobile Station (MS) in a communication system. The method includes when a candidate list of the member BSs generated using at least one of strengths of signals received from adjacent BSs and cell loading state information of the adjacent BSs is received from the MS, selecting candidate BSs having a service quality larger than or equal to a threshold from candidate BSs included in the candidate list as targets to receive a member negotiation; and performing a capability negotiation with each of the selected targets to receive the member negotiation to select final member BSs and transmitting information on the determined final member BSs to the MS.

Abstract: 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.

Abstract: Methods and apparatuses are provided for operating a Mobile Station (MS). A service flow is established with a Base Station (BS). Data is transmitted through the service flow to the BS at an access admission time. A first group control signal indicating a data communication interruption for the service flow is received from the BS at an access restriction time. Transmission of the data to the BS is ceased together with the ceasing of a data transmission from another MS of a group according to the first group control signal.
