PURPOSE: A method for performing a handover in a multi-carrier wave wireless access system is provided to perform handover without cut of data transceiving during handover. CONSTITUTION: A terminal receives an AAI_HO-CMD(Advanced Air Interface_Handover-Command) message form a serving BS(Base Station)(S330). Based on the AAI_HO-CMD(Advanced Air Interface_Handover-Command) message, the terminal performs network reentry with a target BS(S340). A data path is set between the terminal and the target base station(S360). The AAI_HO-CMD(Advanced Air Interface_Handover-Command) message includes information for handover to the target BS and information about whether the target BS supports a handover which uses multi carrier.

Abstract:
PURPOSE: A method for broadcasting location information of a base station and a receiving method thereof are provided to quickly detect a wireless network and reduce power consumption of a multi mode terminal. CONSTITUTION: A serving base station broadcasts a primary LBS advertisement message(S410). An MS gets broadcast time interval information about the second LBS-ADV message(S430). The serving base station separates location information of base stations belonging to overlapped/adjacent wireless networks(S440). The serving base station broadcasts the second LBS-ADV messages in response to corresponding broadcast time interval information.
Abstract:
A method and an apparatus for transceiving data are provided to reduce a queuing delay of data by maximizing use of a BSN(Block Sequence Number). A transmitter assigns a BSN to each block(S602). The transmitter transmits 0~9 blocks to a receiver(S604). The receiver generates ACK(Acknowledgement) and NACK(Non-Acknowledgement)(S608,S610). The ACK/NACK is transmitted to the transmitter(S612). The transmitter assigns the BSN to a new SDU(Service Data Unit) block as the number of blocks which receives the ACK(S614). ARQ-TX-NEXT-BSN is updated(S616). The receiver stores the received data block in a DATA Q(S622,S624). The receiver moves the block having the BSN to the DATA Q belonging to a Window range(S626,S628). The ACK/NACK is transmitted to the transmitter(S630,S632). The transmitter transmits the new SDU block including the new BSN(S634).
Abstract:
An uplink scheduling method is provided to reduce influence of an adjacent cell due to transmission power of a mobile station, thereby increasing uplink transmission efficiency of the adjacent cell. An interference amount of frequency bands corresponding to each of at least one adjacent cell is received(S110). A plurality of interference numerical values corresponding to the frequency bands is calculated by using the interference amount corresponding to each of at least one adjacent cell(S150). Scheduling control information corresponding to a mobile station is obtained by using the interference numerical values(S160). The scheduling control information is transmitted to the mobile station(S170).
Abstract:
A method for allocating resources and a method for receiving data are provided to control a transmission error of data received through a relay station uplink dedicated channel. A base station transmits a resource allocating message to a relay station(S310), and receives a receiving confirmation message about the resource allocating message from the relay station(S320). The receiving confirmation message is included in a header of a relay station uplink dedicated channel. The base station confirms success of a resource allocation in receiving the receiving confirmation message(S340). If the base station does not receive the receiving confirmation message about the resource allocating message from the relay station, the base station retransmits the resource allocating message to the relay station(S330).
Abstract:
A method for re-allocating radio resources in a fixed allocation mode is provided to remove discontinuous unused areas of radio resources which can be generated due to the release and change of resources. A method for re-allocating radio resources comprises the following steps. A map which includes the re-location counter information element from a base station(S220) is received. The first relocation counter are compared with and the second relocation counter(S260). The fixed wireless resources is assigned again based on the comparison result(S290). The number of frames of a map which is not received is compared with a preset number. Data transmission is stopped at each frame(S270). Whether the map transmission time from the base station is completed or not is determined. The fixed wireless resources are released(S340).
