摘要： A method and HARQ memory apparatus in a BWA communication system are provided where the HARQ memory apparatus includes a memory configured to partition the entire memory area in units of slots corresponding to the size of a concatenation block, to input/output a plurality of channel data to the slot in units of the concatenation block, to store a new concatenation block in an empty slot, and to combine a retransmitted concatenation block with a prestored concatenation block and store the combined concatenation block at a prestored location. Accordingly, the required amount of memory can be reduced by using a buffer efficiently. In particular, when a memory is embedded in an integrated circuit, the size and power consumption of the integrated circuit can be reduced.

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： An apparatus and method for controlling operation states of a medium access control layer by a mobile subscriber station (MSS) in a broadband wireless access communication system. The method includes: state-transitioning into a sleep state or an idle state when there is no data transmitted between a base station and the MSS during a predetermined first time interval in an awake state; and performing a location change in the idle state when the mobile subscriber station moves from a first paging zone to a second paging zone, and state-transiting into the awake state when the mobile subscriber station in the idle state detects a paging to the mobile subscriber station. The method minimizes power consumption and maximizes efficiency in use of radio resources.
