AB  - The use of millimeter-wave band is a promising candidate for improving performance of 5th generation
mobile communication systems because of the vast amounts of available radio resources. However, in the very
near future, data traffic is also expected to rapidly increase, due to the explosion of various multimedia services
via. mobile communication. In this scenario, spectral efficiency enhancement will become important. In this
study, a spectrum utilization for spatial division multiple access is proposed. In the system, the base station
uses beamforming antenna array to radiate signal in a particular direction to the desired user for the downlink.
Reversely in uplink, a beam is generated toward the desired user to receive the wanted signal as well as to reject
the interference. As a result, the base station can serve multiple users separately in the space domain. In this
approach, the base station assigns the users which do not interfere with each other in the same radio resource.
On the other hand, if users cannot be spatially separated, they will be assigned the disparate channels. The
proposed scheme is expected to significantly enhance overall capacity of the network compared to the
traditional schemes.
