摘要： A method and apparatus for adaptively selecting a Peer-to-Peer (P2P) communication mode in a wireless communication system are provided. In a method of operating a Base Station (BS) for establishing a P2P connection between Mobile Stations (MSs) in the wireless communication system, the method includes, upon receiving a connection request message from a transmitting MS, broadcasting an instruction message to one or more neighbor MSs, receiving P2P-related information from a receiving MS among the neighbor MSs, selecting a communication mode by determining whether P2P communication is possible between MSs according to the P2P-related information and, if P2P communication is possible between the MSs, transmitting a connection response message to the transmitting MS and the receiving MS.

摘要： An apparatus and method for reducing pilot overhead in a multi-antenna system are provided. The method generates postcodes and pre-codes for streams used to transmit signals to at least two receivers. The method allocates a pilot signal to at least one of the streams, and allocates an additional pilot signal shared by at least one of the streams. The method precodes the pilot signal allocated to at least one of the streams, the additional pilot signal, and data to be transmitted to each of the receivers, based on the pre-code for each of the streams, prior to transmission.
