摘要： A ranging apparatus in a communication system is provided. A terminal generates a ranging code for ranging with a base station, maps the ranging code to at least one sub-carrier so the ranging code is repeated in a time domain, generates a ranging signal so the mapped ranging code has a size of one symbol interval, and transmits the generated ranging signal to the base station. The base station receives a ranging signal, extracts a half signal of a valid symbol interval of the ranging signal, generates a valid symbol interval signal by repeating the extracted half signal of the valid symbol interval, restores a ranging signal using the valid symbol interval signal, and performs ranging using the ranging signal.

摘要： A method and an apparatus operate multi-user Collaborative Spatial Multiplexing (CSM) in a wireless communication system. A Base Station (BS), performs uplink transmission scheduling on multiple Mobile Stations (MSs). Resources units, which have been allocated to multiple layers spatially discriminated by the uplink transmission scheduling, are permutated by applying different permutation schemes according to layers. Uplink data is received from the scheduled MSs through the permutated resource units. Each MS uses permutation schemes according to the layers allocated in a manner corresponding to the BS. Therefore, when the multi-user CSM is used, self-interferences or interferences between layers are averaged, thereby reducing variable widths of parameters of various kinds and improving the prediction property of a received SINR. As a result, a Packet Error Ratio (PER) performance is improved when data is actually transmitted.
