摘要： In a communication system, a terminal receives user information while an initial network entry operation is performed. The terminal transfers the received user information to an authentication server and receives an authentication information mapped to the user information required for the authentication from the authentication server. The terminal performs authentication with the authentication server using the received authentication information. Therefore, the terminal and the authentication server can securely share the authentication information, and the authentication server can easily change and manage the authentication information.

摘要： An apparatus and method is provided for transmitting a signal in a communication system. Upon transition to a power saving mode, a lower layer unit sends a notification indicating the transition to the power saving mode to an upper layer unit. Upon receipt of the notification indicating the transition, the upper layer unit activates a traffic filter having a filtering condition. If upper layer traffic is generated after activating the traffic filter, the upper layer unit filters the upper layer traffic using the traffic filter, and processes the upper layer traffic according to the filtering result.

摘要： A synchronization extraction apparatus for a communication system and a method thereof are disclosed. A frame synchronization is obtained in a manner that the sum of an input signal and a delay signal is obtained without obtaining a simple correlation value between the input signal and the delay signal, and then a correlation value between a summed signal and the delay signal is obtained. The synchronization extraction apparatus and method can reduce the implementation complexity and power consumption in obtaining the frame synchronization, and thus increase the battery cycle of a terminal provided with the synchronization extraction apparatus or method.

摘要： A method and apparatus are provided for adaptively allocating pilots in a pilot-aided channel estimation system. A multipath delay is measured between a base station (BS) and a mobile station (MS). A distribution density of pilots of a signal to be transmitted between the BS and the MS is controlled. When the multipath delay is large, the pilot distribution density is relatively raised. However, when the multipath delay is small, the pilot distribution density is relatively lowered. The pilot distribution density is adaptively controlled according to the multipath delay, such that resources are effectively utilized and throughput is improved.

摘要： Disclosed is an apparatus and method for estimating a start point of a frame in a wireless communication system. The method includes the steps of receiving a frame and estimating the start of the frame by searching for an interval or point of time during or at which a correlation between preambles is at its maximum. At this time, to in order to estimate the start of the frame, a cyclic prefix is used. Thus, a correlation between a cyclic prefix and the last interval of a symbol, which is the same as the cyclic prefix, is calculated and an interval or point of time having the maximum correlation is estimated as the start point of the cyclic prefix. Therefore, the start point of the frame can be accurately estimated based on the start point of the cyclic prefix.

摘要： A method and apparatus for estimating interference and noise power in an orthogonal frequency division multiplexing/orthogonal frequency division multiple access/discrete multi-tone (OFDM/OFDMA/DMT) system is disclosed. A correlator correlates a plurality of sub-carriers with a preset reference sequence on an element-by-element basis and outputs a result of the correlation. A signal noise producer calculates a difference between a correlation value associated with each of the plurality of sub-carriers output from the correlator and a correlation value produced from at least one adjacent sub-carrier and outputs a result of the calculation. An interference and noise power producer produce interference and noise power from the difference between the correlation values calculated by the signal noise producer.

The common control information includes first information that all of the plurality of subscriber stations commonly receive and second information that the plurality of subscriber stations separately receive according to channel states of the plurality of subscriber stations. The first information is decoded by demodulating and decoding the common control information according to a modulation scheme and a coding scheme corresponding to an MCS (Modulation and Coding Scheme) level applied to the first information in the base station. The second information is decoded by demodulating and decoding the common control information according to a modulation scheme and a coding scheme corresponding to MCS levels applied to the second information in the base station.
