COMMUNICATION DEVICE AND COMMUNICATION METHOD USING MILLIMETER-WAVE FREQUENCY BAND
First Claim
1. A wireless communication device using a millimeter-wave frequency band comprising:
- a beam scheduling unit configured to schedule uplink and downlink beams corresponding to movement of a terminal;
a core network interface unit configured to transmit data provided from the beam scheduling unit to a core network, and to provide data received from the core network to the beam scheduling unit;
a mobility management unit configured to configure an uplink and downlink beam set based on inter-beam interference information provided from the beam scheduling unit; and
an inter-base station interface unit configured to exchange a control message with another base station under control of the mobility management unit.

Abstract
There are provided a communication device using a millimeter-wave frequency band and a communication method using the millimeter-wave frequency band. The communication device includes a beam scheduling unit configured to schedule uplink and downlink beams corresponding to movement of a terminal, a core network interface unit configured to transmit data provided from the beam scheduling unit to a core network, and to provide data received from the core network to the beam scheduling unit, a mobility management unit configured to configure an uplink and downlink beam set based on inter-beam interference information provided from the beam scheduling unit, and an inter-base station interface unit configured to exchange a control message with another base station under control of the mobility management unit. Therefore, it is possible to efficiently build a cellular network using the millimeter-wave frequency band.
