摘要： A transmission method based on random beamforming. A base station receives, from mobile stations, feedback information including channel-by-channel transmission rates for a weight vector arbitrarily set by the base station. The base station compares transmission rates of identical channels received from the mobile stations. The base station allocates an associated channel to a mobile station with a large transmission rate and transmits a signal through the allocated channel. The transmission method based on random beamforming can improve fairness and efficiency of a resource allocation by simultaneously allocating different channels to multiple terminals and can increase a total system capacity through the improved fairness and efficiency.

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.
