    摘要： In a call forwarding system, a management apparatus of the call forwarding system determines service terminals capable of near field wireless communication within a reception range of near field wireless communication, generates a terminal list, and receives a call event message reporting the receipt of a call from a reference terminal. The management apparatus may transmit a call report message including the terminal list to the reference terminal and the service terminals. The management apparatus may forward the call initially received by the reference terminal to a terminal which transmitted a receipt request message by transmitting a call forwarding request message to the reference terminal. The management apparatus may transmit, to the reference terminal and the service terminals, a receipt report message reporting the call was forwarded. According to a change receipt message or upon non-receipt by an intended terminal, the call may be reforwarded to another terminal.

    摘要： The present invention relates to precoding and feedback channel information in wireless communication system. A method includes receiving a first Precoding Matrix Index (PMI) and a second PMI from a terminal; mapping one or two codewords into layers; precoding symbols mapped into the layers using a first precoding matrix derived from the first PMI and a second precoding matrix derived from the second PMI; and transmitting the precoded symbols to the terminal, wherein the reception of the first PMI is less frequent than the reception of the second PMI.

    摘要： The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.
