摘要： The present invention relates to a method of detecting a space-time code in a mobile communication system. When detecting a space-time code B for a plurality of transmitting antennas, an ML (maximum likelihood) metric, which is generally calculated by using a specific structure of a matrix B, is defined as a new ML metric by reducing a variable of the ML metric. Two dependent sphere decoding processes are performed and an intersection of the decoding results is calculated, and a signal is detected from the ML metric. Therefore, since detection of the space-time code B for the plurality of transmitting antennas is performed by using the newly defined ML metric, an amount of matrix calculated can be reduced, and a calculation amount can be reduced by performing the two dependent sphere decoding processes. Further, since a detection order of symbols is changed according to a channel situation, it is possible to improve the performance of the system.

摘要： The present invention relates to a beamforming device in an orthogonal frequency division multiplexing access system, and a method thereof. In the method, a switched beamforming algorithm is applied to perform downlink beamforming, and an adaptive beamforming algorithm is applied to perform uplink receiving beamforming. In addition, a half wavelength array antenna is used to simultaneously allocate the same resource to two terminals separately positioned in two different spaces, so as to support spatial division multiple access (SDMA). In this case, since a base station uses channel status information at transmitter (CSIT) for transmitting beamforming and receiving beamforming, the SDMA may be supported without obtaining additional channel status information at receiver (CSIR) when realizing the uplink receiving beamforming.

摘要： The present invention relates to a method for generating/changing a transport connection identifier (CID) in a portable Internet System, and a terminal using the same. Accordingly, the present invention provides a terminal including a packet detecting unit, a user input/output unit, a CID managing unit, and a data storing unit. The packet detecting unit determines whether a packet can be classified by a pre-established packet classification rule or a packet cannot be classified by the rules (5304). For the packet that cannot be classified by the pre-established packet classification rule, the user input/output unit receives QoS information from a user (5322, 5324). The CID managing unit generates a new packet classification rule for the unclassified packet (5326), checks a CDD in a data storing unit (5328), the CID having the same QoS class as that of the QoS parameter input through the user input/output unit, and determines whether to generate a new CID (5340) or to add the new packet classification rule to the pre-established CID (5330) depending on the checking result. The data storing unit storing unit Stores the new packet classification rule generated by the CID managing unit and information on the CID (5354).

摘要： In the method for dynamic IP allocation using a mobile IP in a wireless portable Internet system, a MAC message used to register a mobile subscriber station contains a flag including a mobile IP version parameter. Upon checking the mobile IP version, the mobile subscriber terminal transmits a mobile IP registration request message to a base station during MAC connection establishment. The base station transmits a mobile IP registration reply message to the mobile subscriber in response to the received mobile IP registration request message to allocate a dynamic IP address to the mobile subscriber station. The dynamic IP allocation process is performed through a secondary management connection to achieve a rapid handoff without using a connection identifier. In addition, the present invention supports a seamless service and the use of the mobile IP in the IEEE 802.16e wireless
