    摘要： There are provided a transmitting/receiving apparatus and method for packet data service in a mobile telecommunication system. To determine the transmission format of packet data between a first format and a second format longer than the first format based on at least one channel state value received from a mobile station, received channel state values are sequentially stored. Then, the differences between all adjacent channel state values are calculated and summed. The sum is compared with a predetermined threshold. If the sum is greater than or equal to the predetermined threshold, the transmission format of the packet data is determined as the first format. If the sum is less than the predetermined threshold, the transmission format of the packet data is determined as the second format.

    摘要： An apparatus and method are disclosed for acquiring by a mobile terminal a pseudo-random noise (PN) sequence of a pilot signal received from a base station by means of a searcher, designating a phase of the acquired PN sequence as a reference phase to track the phase of the acquired PN sequence, and measuring an energy difference between an early path and a late path for the reference phase in a mobile communication system. In the apparatus and method, a first energy measurer measures a first energy value from a PN sequence with the reference phase, and a second energy measurer alternately measures energy values of the early path and the late path for the reference phase and outputs a second energy value. A first normalizer normalizes the first energy value with the second energy value, and a delay processor delays the normalized energy value for a predetermined time; a subtractor calculates a difference between the normalized energy value output from the first normalizer and the energy value output from the delay processor.

    摘要： A system and method for transmitting and receiving a signal in a communication system using a relay scheme. A base station receives a first signal in a first time interval from a first mobile station which is at least one mobile station located in a third region which is a region where a first region which is a region of the base station itself overlaps with a second region which is a region of a relay station. The relay station receives a second signal in the first time interval from a second mobile station which is at least one mobile station located in a fourth region which is a region not overlapping with the first region in the second region, and receives the first signal from the first mobile station. The relay station transmits a third signal including the first signal and the second signal to the base station in a second time interval. The base station receives the third signal in the second time interval, and cancels the first signal from the third signal to detect the second signal.

    摘要： A method and apparatus for joint unicast using multi-user superposition coding in a wireless relay system are provided. A BS superposition-encodes first and second data messages directed to first and second MSs, respectively, scheduled at a current scheduling instant. The first and second data messages carry first and second information bit streams for the first and second MSs, respectively. The first MS has a relatively good direct link to the BS, and the second MS has a relatively bad direct link to the BS. The superposition-coded data is transmitted to the first MS and an RS connected between the BS and the first and second MSs. The RS receives the superposition-coded data from the BS, extracts the second information bit stream by decoding the superposition-coded data, and transmits a third data message carrying the second information bit stream to the first and second MSs.
