Abstract: A method and a system for transmitting and receiving signals using multiple frequency bands in a wireless communication system are provided to transmit and receive mass data by assisting an MS(Mobile Station) to use a plurality of FAs(Frequency Assignments) in a wireless communication system. An MS acquires synchronization with a BS(Base Station) through a specific FA(201). The BS and the MS execute initial ranging through the exchange of ranging messages(203). The MS transmits an SBC-REQ(Subscriber Basic Capability Request) message to the BS(205). In this case, the SBC-REQ message contains information about whether the MS supports overlay mode and information about the maximum number of usable FAs when the MS supports overlay mode. In response to the SBC-REQ request, the BS transmits an SBC-RSP(SBC Response) message to the MS(207). In this case, the SBC-RSP message contains information about whether the BS supports overlay mode and information about the number of FAs to be provided when the BS supports overlay mode. Afterwards, the BS executes authentication and registration procedures with the MS(209,211).

Abstract: An apparatus and a method for transmitting frame information in a multi-hop relay broadband wireless access communication system are provided to configure a frame adaptively according to a cell environment variable and accurately decode corresponding frame information. When a broadband wireless access communication system includes two hops, sub-frames(300,310) are divided into first regions(301,311) and second regions(303,313). Here, the fourth regions(307,317) exist between the first regions and the second regions. However, when the broadband wireless access communication system includes two hops, the fourth regions do not exist, so the first regions and the second regions can extend up to the fourth regions. A base station and a relay station performs communication with a terminal included in a service area of them during the first regions. The base station performs communication with the relay station during the second regions.

If ARQ feedback information is received from the mobile station(506), the serving BS stops data transmission to the mobile station(508). The serving BS grants a virtual SDU SN in consideration of the SDU SN contained the ARQ feedback information received from the mobile station(510). The serving BS notifies a target BS that the mobile station will execute handover(512). The serving BS transmits SDU information, which will be provided to the mobile station, to the target BS(514).

Abstract: An apparatus and a method for transceiving channel information in a relay wireless communication system are provided to perform data scheduling in a long-time period, not each frame, for a RS in which a change of channel is not great, thereby reducing overhead. An RS(Relay Station)(41) and a BS(Base Station)(40) perform a registration process for data communication. The RS and the BS perform a DSA(Dynamic Service Addition) process. The BS transmits a channel measurement request message to the RS. The RS estimates a channel according to the information of the channel measurement request message and transmits a channel measurement response message including channel estimation information to the BS. The BS performs data scheduling by using the channel information and makes and broadcasts resource allocation information, DL-MAP/UP-MAP(DownLink-MAP, UpLink-MAP), according to the data scheduling result. The BS and the RS perform data communication based on the resource allocation information. The BS transmits a channel measurement update request message to the RS when it is determined that it is necessary to update the channel information of the RS. The RS estimates a channel according to the information of the received channel measurement update request message, and transmits a channel measurement update response message including the channel estimation information to the BS.

Abstract: An apparatus and a method for providing encoding information for an R-FCH(Relay Station Frame Control Header) in a BWA communication system which uses a multihop relay scheme are provided to efficiently use resources by determining the encoding scheme of an R-FCH in consideration of the channel state between an RS and a BS(Base Station) and adaptively applying the determined encoding scheme according to the channel state. An RS(Relay Station)(410) executes an initial network entry procedure with a BS(450)(411). In this case, the initial network entry procedure is executed at the first sections of a BS frame. The BS monitors the channel state with the RS while executing the initial network entry procedure(413). After monitoring the channel state, the BS determines the encoding information of an R-FCH according to a monitoring result(415). Then the BS transmits the determined frame control encoding information to the RS(417). Receiving the frame control encoding information, the RS acquires encoding information necessary to decode the R-FCH(419). Then the RS completes the initial network entry procedure(421).

Abstract: An apparatus and a method for supporting a relay service in a wireless communication system by using a multi-hop relay manner are provided to offer time protection area information from a base station to a relay station, thereby setting the synchronization between a relay station and a base station exactly. A frame generator(1109) produces a frame according to a control signal provided from a timing controller(1105). A resource mapping device(1111) allocates each sub frame received from the frame generator to a burst of each link. A modulator(1118) modulates the allocated sub frames of each burst according to the corresponding MCS(Modulation and Coding Scheme). A digital/analog converter(1115) converts the digital signal received from the modulator into analog signals and outputs the converted analog signals to an RF(Radio Frequency) switch(1107). An analog/digital converter(1117) converts the analog signals received through the RF switch into the digital signal. A digital demodulator(1119) demodulates the digital signal received from the analog/digital converter according to the corresponding MCS. A resource de-mapping device(1121) extracts the real frames allocated to the burst of each link. A frame extractor(1123) extracts the sub frame corresponding to the relay station from sub frames received from the de-mapping device.
