摘要:
A method of transmitting data from a terminal in a cellular system is provided. The data transmission method includes: calculating the transmission capacity of a predetermined number of vectors among pairs of orthogonal vectors; selecting the vector having the largest transmission capacity as a reference vector among the predetermined number of vectors; and transmitting data to a base station using the reference vector.
摘要:
Virtualization information on a first user terminal is generated and is stored in a data storage device through a mobile communication system. When a user with a second user terminal requests virtualization information while the second user terminal provides a first identification number of the first user terminal, the mobile communication system provides virtualization information corresponding to the identification number to the second user terminal. The second user terminal operates the virtualization information corresponding to the first identification number.

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.
