摘要： Provided is a method and apparatus for determining timing for initial ranging of user equipment by using ranging of adjacent pieces of user equipment in a multi-hop mobile relay (MMR) system, and more particularly, a method and apparatus for determining timing for initial ranging of user equipment in which a power value and a timing value for periodic ranging of adjacent pieces of user equipment are measured so as to minimize an uplink timing error of a base station. In the MMR system, user equipment transmits an initial ranging code to the base station with irregular timing while not knowing an exact start point of an uplink of the base station. In particular, if the user equipment attempts the initial ranging at the same time as when adjacent pieces of user equipment attempt the periodic ranging and the handover ranging, an error occurs between transmission timing of the initial ranging and uplink timing, thereby acting as an inter-symbol interference (ISI) and inter-channel interference (ICI) of different ranging. As a result, the initial ranging acts as an interference signal in a ranging process of adjacent pieces of user equipment. However, the apparatus and method can minimize a timing error of the initial ranging code of user equipment by avoiding the initial ranging acting as the interference signal.

摘要： Provided are a method of controlling power of an access uplink using a relay station (RS) and a system thereof. When a base station (BS) decides that the subject of power control of the access uplink is itself, the BS generates a message for power control of the access uplink based on channel quality measurement information reported from the RS and transmits the power control message to a subscriber station (SS), and when the BS decides that the subject of power control of the access uplink is the RS, the RS generates a message for power control of the access uplink based on channel quality measurement information and transmits the power control message to the SS. Thus, fast power control of the access uplink can be performed.

摘要： The present invention relates to an apparatus and method for variable fast Fourier transform. According to an embodiment of the present invention, two n-point fast Fourier transform (FFT) processors are used to generate two n-point FFT output data or one 2n-point FFT output data. The one 2n-point input data is alternately input to the two n-point FFT processors. Each of the two n-point FFT processors selects a twiddle factor for the n-point input data or the 2n-point input data and performs fast Fourier transform. A butterfly operation is performed on signals obtained by performing fast Fourier transform on the 2n-point input data signal, and the processed signals are aligned in an output order. According to this structure, it is possible to realize a fast Fourier transform hardware engine that selectively performs multi-frequency allocation in a base station system that supports the multi-frequency allocation.

摘要： Provided are a method of relaying a data burst in a relay station (RS) of a multi-hop relay (MMR) system using a direct relay zone, and a system using the method. The RS requests a base station to assign the direct relay zone in a frame in which a demodulation and forwarding scheme that demodulates, and then modulates and transmits a data burst is applied, receives an acknowledgement to the request from the base station, and relays a data burst using the frame in which the direct relay zone is assigned. Accordingly, since a data burst can be relayed within one frame, relay latency can be reduced.
