    摘要: Provided is an antenna control apparatus for controlling an antenna mounted on a stratospheric platform of the stratospheric communication system. The apparatus includes a plurality of location signal receivers, each receiver being positioned at each of predefined different points of the stratospheric platform and receiving a location signal for the stratospheric platform, a calculating circuit for calculating an adjustable displacement for the antenna, and an antenna driver for adjusting a direction of the antenna. The calculating circuit calculates a location and attitude of the stratospheric platform based on the location signals, and then computes the adjustable displacement using the location and attitude information. This invention can reduce power consumption in the stratospheric platform and recovery time of directional point of the beam.

    摘要: First resource blocks of a radio resource each include a first number of subcarriers and a second number of subframes having the first size. In this case, second resource blocks are formed, each second resource block including fewer subcarriers than the first number and fewer subframes than the second number based on the first resource blocks. A signal is transmitted in the first resource block or second resource block, and particularly, signals of first and second channels are transmitted by sharing the first resource block.
