摘要： An apparatus and method for channel encoding/decoding are provided which vary an iterative decoding number according to service type, data class and channel condition. A message information receiver receives information about a message to be received. A controller determines an iterative decoding number according to the message information received. A decoder iteratively decodes the received message according to the determined iterative decoding number. The message information includes a class of received data, and the class includes a bit error rate (BER). The iterative decoding number is increased for a low BER as compared to a predetermined BER. Further, the class includes a permissible time delay, and the iterative decoding number is increased for a long permissible time delay as compared to a predetermined permissible time delay. In addition, the message information includes a service type of the received data, and the iterative decoding number is decreased when the service type is a moving picture service.

摘要： A method of performing an inter-RAT measurement for a handover from NB-TDD to GSM is provided. A UE, as it moves from an NB-TDD Node B to a GSM cell, receives a measurement control message from the NB-TDD Node B. The UE then measures the strength of a signal received from the GSM cell and verifies its identification for a predetermined measuring time. If the UE successfully verifies the identification of the GSM cell for the measuring time, it reports the signal strength measurement and the verified GSM cell identification to the NB-TDD Node B. If the UE fails to verify the identification of the GSM cell for the measuring time, it reports only the signal strength measurement to the NB-TDD Node B.

摘要： An apparatus for reporting downlink channel quality in a high-speed packet communication system. A channel analyzer measures downlink channel quality from a received reference channel signal. A controller determines whether a current TTI (Transmission Time Interval) is a TTI corresponding to a multiple of a first TTI or a TTI corresponding to a multiple of a second TTI. If the current TTI is a TTI corresponding to a multiple of the first TTI, the controller determines CQ (Channel Quality) refreshment information for a downlink channel received from the Node B based on the measured downlink channel quality, and if the current TTI is a TTI corresponding to a multiple of the second TTI, the controller determines CQ refinement information for the downlink channel based on the measured downlink channel quality. A CQ information transmitter generates CQ refreshment information or CQ refinement information under the control of the controller, and transmits the generated CQ refreshment information or CQ refinement information over an uplink.

摘要： A beam-forming apparatus and method for improving system performance using a spatial interpolation and at least one Angle of Arrival (AoA) in a system based on regular spatial sampling is provided. The AoA is estimated using a carrier-to-interference ratio. Beam-forming angles are distributed and steered in a predefined scheme such that an identical process is applied in all directions. According to this steering, a linear system model is computed based on regular spatial sampling using regular spatial separation at beam angles. Beam-forming performance is improved by compensating for a difference between adaptive and sector-type arrays. Only the steps of computing a spatial interpolation and determining an angle range for beam-forming using at least one AoA are added. The precision of estimating an AoA and the precision of beam-forming increase without an additional antenna. Because the system is simpler than that of an adaptive beam-forming system, significant gain is obtained.

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.
