摘要： Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

摘要： Disclosed is a method for allocating and accessing downlink resources in the OFDMA communication system. In the resource allocation method, bursts having the same modulation and channel encoding level are arranged in a predetermined temporal order on a physical layer. Information on the allocated unit resources is included in a common control block and is transmitted to a subscriber station, and the subscriber station then detects a number of the allocated unit resources to thus check the range of bursts to be received by the subscriber station. Therefore, power consumption by the subscriber station is reduced and signaling overheads of the common control information and unneeded residual resources are decreased.

摘要： The present invention relates to a method of transmitting/receiving random access response information in a radio communication system, and a base station and a terminal thereof. According to the invention, in a case where a base station of a radio communication system transmits response information for random access processing requested from terminals, the base station determines whether to transmit non-contention-based response information and contention-based response information for each of one or more terminals, which requests random access, by one radio resource. When determining to be transmitted by one radio resource, the base station transmits the random access response information configured by the non-contention-based response information and the contention-based response information for each of one or more terminals. In addition, when determining to be transmitted by separate radio resources, the base station transmits the random access response information configured by the non-contention-based response information or the contention-based response information for each of one or more terminals. Accordingly, since the response information is efficiently configured from the point of view of allocation and utilization of radio resources, it can support variable and flexible utilization of physical layer radio resources.
