摘要： Disclosed is a method of preventing a replay attack during a handoff in a communication system using a Mobile IPv6 protocol. A mobile node creates a CoA (Care of Address) by handoff and sends the CoA to a correspondent node, thereby creating a binding entry. Upon receipt of a binding update message including a HoA and a CoA from the mobile node or an attacker, the correspondent node searches a binding cache for a binding entry having the same HoA (Home Address) and CoA as included in the binding update message. If it is determined that the binding entry has the same respective HoA and CoA as contained in the binding update message, the correspondent node checks a Used field of the binding entry. If it is determined that the Used field of the binding entry is equal to a predetermined value, the correspondent node sends a reauthentication command message to the mobile node.

摘要： Provided is an apparatus and method for simultaneously receiving data signals of two adjacent frequency allocation (FA) in a cellular environment. When there is another base station using an adjacent FA to an FA of the base station, a subcarrier mapper maps control information to subcarriers of predetermined sections such that a mobile station simultaneously receives data signals of the adjacent FAs. An inverse fast Fourier transform (IFFT) processor IFFT-processes data mapped to the subcarriers. Because two different BSs transmit the same data through independent paths, the mobile station can obtain a macro diversity gain. Also, it is possible to balance the loads of the two BSs.

摘要： An apparatus and method for improving the reception performance of a Mobile Station (MS) in a multiple antenna system are provided. In an apparatus of a Base Station (BS) in the multiple antenna system, upon receipt of a request for interference cancellation for a first MS serviced by a neighbor BS, a channel estimator estimates a channel from the first MS and a channel from a second MS serviced by the BS. A beam coefficient generator generates a first beam coefficient based on channel estimates of the first and second MSs and a second beam coefficient based on the channel estimate of the second MS. An interference cancellation decider determines whether to perform interference cancellation for the first MS using the first and second beam coefficients.
