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

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： The method for controlling a use amount of a radio channel for transmitting a packet from a node in a wireless Ad Hoc network that employs a contention-based protocol includes (a) estimating a total amount of data transmitted through packet transmission from the node; (b) controlling a backoff time that determines the use amount of the radio channel based on the estimated amount of transmitted data; and (c) participating in contention for gaining access for the next packet transmission by using the backoff time. A contention window value for setting the bounds of backoff time can be set by calculating a total amount of data transmitted through a transmit node, and thus channel distribution can be controlled such that a plurality of transmit nodes can fairly transmit data through the channel, thereby enhancing quality of packet data service.
