摘要： Disclosed is a distributed antenna system that selects an antenna in accordance with the position of a mobile terminal and reduces the variation in the total number of mobile terminals using each antenna while maintaining adequate communication quality. In the distributed antenna system in which a large number of antennas are distributively disposed, an antenna group including antennas having good communication quality is selected in accordance with the position of a mobile terminal. Further, in accordance with the communication quality and load status of a current antenna group and with the communication quality and load status of a post-change antenna group, which is obtained by changing some antennas in the current antenna group, the post-change antenna group is formed by changing some antennas in the current antenna group with which a mobile terminal using a heavily loaded antenna communicates.

摘要： In a method by which a base station detects a random access signal transmitted by a user equipment to send a transmission request to the base station in uplinks, the base station omits a MF used only to detect the random access signal, or Fourier transform and inverse Fourier transform meeting the random access signal, and uses a Fourier transform unit for data reception to detect the random access signal. Using output of the Fourier transform unit for data reception, which transmits all received signals to frequency region signals, it is judged whether a random access signal is received by a power pattern of bands allocated to the random access signals in one transmission time interval.
