In a high rate WPAN environment including a plurality of piconets, a piconet controller (PNC), which performs a topology server function to provide the optimal route, collects link state information from the PNCs or DEVs (devices) belonging to a sub-tree that serves as a root and applies a minimum cost algorithm based on the collected link state information to calculate the optimal route for all pairs of originations and destinations existing within the sub-tree in consideration of QoS. The optimal route information is transmitted to the origination PNC via the destination PNC/DEV. During performing this, the optimal route between the pairs of originations and destinations is set.

    摘要: An apparatus and method to transmit/receive a signal in a communication system are provided. A base station (BS) generates repetitive information by repeating information a number of times, allocates a subcarrier for transmitting the repetitive information using a subcarrier allocation scheme that all BSs included in the communication system use in a same way, and transmits the repetitive information using the allocated subcarrier. When the communication system includes a serving BS and one interference BS, a mobile station (MS) detects R-times repeated information from a corresponding subcarrier of a signal received via K reception antennas, estimates a channel using the received signal, reassembles the detected information, and performs R×2×k Minimum Mean Square Error (MMSE) processing on the reassembled information using the channel-estimated value.
