Abstract: A device for bidirectional transmission in a relay-type wireless communication system and a method therefore are provided to carry out bidirectional transmission by using overlapping signals at a signal level, thereby conducting the bidirectional transmission in an AF(Amplify and Forward) repeater. A repeater confirms whether signals are received from two nodes(401). If so, the repeater estimates a channel between the two nodes(403). The repeater generates overlapping signals which add signals to be transmitted to the two nodes, by using estimated channel information(405). The repeater transmits the overlapping signals to the two nodes during the same time interval(407).

Abstract: An apparatus and a method for communicating uplink data in a wireless communication system are provided to save the energy required for uplink transmission by partially transmitting the sample data of an OFDMA(Orthogonal Frequency Division Multiple Access) symbol during the uplink transmission. An apparatus for communicating uplink data in a wireless communication system includes an index generator(505), a pilot symbol mapper(509), a data symbol mapper(507), an IFFT(Inverse Fast Fourier Transform) calculator(511), and a transmitting unit. The index generator calculates and generates a sub carrier index for mapping a transmission packet signal into a sub carrier at a predetermined interval. The pilot symbol mapper performs mapping of a pilot symbol into the corresponding sub carrier according to the sub carrier index in the predetermined front period of a packet signal transmission period. The data symbol mapper performs mapping of a data symbol into the corresponding sub carrier according to the sub carrier index in the predetermined rear period of the packet signal transmission period. The IFFT calculator performs the IFFT of the mapped pilot symbol and data symbol, and generates sample data. The transmitting unit extracts and transmits the predetermined part of the sample data of each OFDMA symbol from the IFFT processor.

Abstract: A method and an apparatus for estimating an uplink frequency offset in a wireless communication system are provided to prevent resource waste by using a random access channel for estimating the uplink frequency offset. A base station of a wireless communication system uses a random access channel having two sequences. A channel receiver(404) extracts samples corresponding to the two sequences from a received random access channel signal. A correlator correlates predetermined former and following samples with a predetermined sequence to calculate first and second correlation values. A frequency offset estimator(422) divides the second correlation value by the first correlation value to estimate a frequency offset. The correlator includes a code generator, a conjugate generator(416) and first and second multipliers(408,412). The conjugate generator outputs complex conjugates of the sequences from the code generator. The first and second multipliers generate the first and second correlation values.
