    摘要： Provided are an apparatus and method for generating channel information and apparatus and method for adaptive transmission employing the same. The channel information generation apparatus comprises an estimator for estimating current channel information of a multi-carrier received signal for each path, a short-period channel information generator for predicting channel information after a predetermined minimum transmission delay time based on the current channel information estimated by the estimator to generate short-period channel information, and a long-period channel information generator for deriving statistic information of error between the channel information predicted by the short-period channel information generator and actual channel information at the time of transmission to produce long-period channel information. The invention is applied to mobile communication systems using multi-carrier.

    摘要： Disclosed is a method for controlling uplink transmit power in a mobile communication system. A mobile communication includes a first base station and a second base station which are located in two mutually adjacent cells, respectively, at least one base station of the first and second base stations which generate a subframe offset of transmit power (SOTP), and transmits a subframe offset of transmit power generated by at least one base station of the first and second base stations to at least one terminal which belongs to a corresponding cell. Accordingly, it is possible to reduce signaling times for transmit power control, and to accurately control transmit power.

    摘要： Provided are an uplink transmission method and downlink transmission method in a mobile communication network including a relay. In the uplink and downlink transmission methods, frame structures and transmission timings of a backhaul downlink and a backhaul uplink are determined in consideration of at least one of a time for the relay to switch between transmission and reception and a signal transmission time. Accordingly, in a wireless communication system including a relay, it is possible to effectively perform data transmission and reception between the relay and a base station.
