    摘要: Disclosed is a system for providing handover of a mobile node in a wireless network supporting Mobile IP (Internet Protocol). The mobile node sends, when handover is needed, a request for neighbor access router information to a first access router currently communicating with the mobile node, and selects, if the neighbor access router information is received, a second access router serving as a target access router using the received neighbor access router information. The first access router exchanges access router information with a neighbor access router, provides neighbor access router information to the mobile node upon receiving the neighbor access router information request from the mobile node, and redirects data to be delivered to the mobile node to the second access router to which the mobile node will be handed over. The second access router forwards data to be delivered to the mobile node, received from the first access router, to the corresponding mobile node.

    摘要: Disclosed is a method and apparatus for transmitting/receiving control information in a system in which one or more Radio Frequencies (RFs) are used to carry multiple services through a frame constituted by time resources or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel through which to transmit primary service traffic among all service traffic, and each non-primary service traffic other than the primary service traffic includes control information for a primary service. Thus, even when a receiver changes the current service to a target service, control information necessary to detect the location of the target service in a frame and demodulate the target service can be acquired, and thus a service change can be made without reading a separate control channel.

    摘要: A channel coding device is disclosed. In the device, a bit inserter inserts known bits in an input data bit stream at predetermined positions. A channel coder codes the bit-inserted data bit stream to generate coded symbols. A rate matcher matches a rate of the coded symbols to a given channel symbol rate. A channel interleaver interleaves the rate matched channel symbols. The rate matcher includes a puncturer for puncturing the inserted known bits included in the coded symbols when the coded symbol rate is higher than the given channel symbol rate. The rate matcher includes a repeater for repeating the coded symbols to match the coded symbol rate to the given channel symbol rate when the coded symbol rate is lower than the given channel symbol rate.

    摘要: A multiple antenna system including a mobile station and a base station are operable to perform a method for transmitting control information for interference mitigation. A Mobile Station (MS) can transmit control information for interference mitigation. The MS determines a first Precoding Matrix Index (PMI) and a second PMI for interference from an adjacent Base Station (BS). Based on a correlation level from correlation values between one of the first PMI and second PMI and the remaining PMIs in the codebook, the MS determines a level of a subset of PMIs, and feeds back information indicating the correlation level.
