摘要： An apparatus for setting a pilot subcarrier in an antenna selects candidates of power value variables of a pilot subcarrier existing within a predetermined range, and calculates and extracts pilot subcarriers of a predetermined number on the basis of a nonlinear function among the candidates of the selected power value variables. Next, the apparatus removes pilot subcarriers of a predetermined number from the extracted pilot subcarriers of a predetermined number in accordance with a rule and configures the antenna on the basis of position values of final pilot subcarriers except for a virtual subcarrier among the removal result. Further, the apparatus configures the antenna on the basis of the power value by determining the sum total of the power values corresponding to the position values of the final pilot subcarriers to correspond to the number of pilot subcarriers.

摘要： A node synchronization apparatus in a wireless network system sets a fast Fourier transform (FFT) start point and requests a one-hop neighbor node to change its transmission time. The synchronization apparatus sets a signal receiving time and requests a one-hop neighbor node to change a receiving time. In this way, a node synchronizes signal transmission and signal reception.

摘要： In a mobile wireless network system including a plurality of nodes communicating with each other, a node attempting to transmit data finds useable resources through performing carrier sensing on packet data unit (PDU) slots and transmits data through the found resources. A node attempting to receive data finds useable resource through performing carrier sensing on acknowledge (ACK) slots and receives data through the found resources.

摘要： To control precoding of a terminal in a serving base station, a first codeword that maximizes transmission power of the serving base station is determined by a codebook, and an index of a second codeword that minimizes interference to the neighboring base station is transmitted from the neighboring base station. The serving base station transmits an index of the first codeword, an index of the second codeword, and a combination ratio of a precoding matrix corresponding to the index of the first codeword and a precoding matrix corresponding to the index of the second codeword to the terminal.
