    摘要: An apparatus and method for controlling power in a multi-hop relay broadband wireless communication system are provided. A BS sends a signal to an RS and an MS to estimate distances between the BS, the RS and the MS. Upon receipt of signals from the RS and the MS, the BS measures ToAs of the received signals and detects time information included in the received signals, and calculates propagation delays between the BS, the RS and the MS based on the ToAs and the time information. The BS estimates the distances between the BS, the RS and the MS using the propagation delays, and controls transmission power according to the estimated distances.

    摘要: A method and system for transmitting/receiving data in a heterogeneous communication system. A terminal accesses a first controller of a first communication system supporting a first communication service to make a communication path to the first communication system. After making the communication path to the terminal, the first controller determines whether it is possible to provide the first communication service to the terminal over the first communication system. If it is not possible, the first controller transmits to an interworking unit a first request indicating that the terminal requires the first communication service over the second communication system. The interworking unit transmits a second request to a second controller of the second communication system in response to the first request, the second request indicating that the second controller provides the first communication service to the terminal. Upon receiving a response to the second request, the interworking unit controls the first controller to provide the first communication service to the terminal over the second communication system according to the response.

    摘要: Provided are an apparatus and method for transmitting data using an Adaptive Modulation and Coding (AMC) scheme in a mobile communication system with a Relay Station (RS). A relay indicator value is received indicating a strength of a downlink signal transmitted to a destination through a relay path including the RS and a direct indicator value indicating a strength of an downlink signal directly transmitted to the destination via a direct path without passing through the RS. Modulation and Coding Scheme (MCS) levels are determined using the relay and direct indicator values for both the relay and direct paths. Bandwidth efficiencies are found in correspondence with the MCS levels and are compared depending on whether the relay path or the direct path is used. A path resulting in a higher bandwidth efficiency is selected to generate a data frame having a structure corresponding to the selected path. The data frame is transmitted to the destination or the RS.
