摘要： An apparatus and method in a heterogeneous wireless communication system reconnect a Mobile Station (MS) to a previously connected cell upon occurrence of a Radio Link Failure (RLF) in a current cell when a portion of a coverage of the second cell is included in a coverage of the first cell. A Mobile Station (MS) stores system information of a first Base Station (BS) of a first cell when performing handover from the first cell to a second cell. When changed system information of the first BS is received from a second BS of the second cell, the MS updates the stored system information using the changed system information. When detecting that a connection with the second cell is lost prior to a handover from the second cell, the MS performs reconnection to the first BS using the stored system information.

摘要： The invention relates to a data transfer method in a multi-hop relay system. The data transfer method comprises: a step for allowing a base station to receive from a first terminal the channel information (Hd,1) between the base station and the first mobile station, a step for making the base station generate an interference cancellation precoding matrix using Hd,1, a step for forcing the base station to transfer first data to a relay station, and a step for making the relay station transfer the first data to the first mobile station and forcing the base station to transfer second data to a second mobile station, wherein the second data is converted using the interference cancellation precoding matrix. According to the disclosed data transfer method in the multi-hope relay system, the base station transfers data to another mobile station efficiently when the relay station transfers data to a mobile station. Therefore, the data transfer method is able to efficiently use the resources wasted in an existing data transfer method and improve the total data transmission rate of the base station.

摘要： A method and an apparatus ensure efficient handover in a wireless communication system even when a User Equipment (UE) moves at a high speed. A serving eNB receives interference power information of an uplink (UL) signal and interference increase/decrease information of the UL signal from at least one adjacent eNB. an adjacent eNB, for which the received interference power information indicates that interference power of the UL signal is equal to or greater than a threshold value, is selected as a target eNB for a User Equipment (UE) among the at least one adjacent eNB. Whether handover of the UE is delayed is determined based on the interference increase/decrease information received from the target eNB. And if the handover of the UE is delayed, a handover parameter is transmitted to the UE to perform handover to the target eNB.

摘要： An apparatus and a method for handover in a broadband wireless communication system supporting a Mobile Relay Station (MRS) are provided. The method includes transmitting a Connection ID (CID) of Mobile Stations (MSs), the CIDs pre-allocated by a target BS, to the MSs; sending a resource allocation message comprising uplink resource allocation information for bandwidth request of the MSs, to the MSs; receiving a bandwidth request message which comprises security authentication information of each MS, from the MSs using an uplink resource allocated through the uplink resource allocation information; and aggregating bandwidth request messages of the MSs and sending a ranging request message comprising the security authentication information and bandwidth request information of the MSs to the target BS. Thus, the handover delay time, which is inevitable for the bandwidth request in the conventional connection set-up procedure, can be reduced, and the handover with the reliability guaranteed can be achieved by allowing the security related processing in the network re-entry procedure.
