Abstract

A Base Station (BS), a Mobile Station (MS), and a millimeter Wave (mmWave) Access Point (mmAP), for use in a mobile communication system that includes a plurality of Base Stations BSs capable of communicating with a plurality of Mobile Stations (MSs), are provided. The BS includes a cellular band transceiver for communicating in a cellular band, an mmWave band transceiver for communicating in the mmWave band, and a controller for controlling both the cellular band transceiver and the mmWave band transceiver for communication with an MS.

First claim

What is claimed is:

1. A millimeter wave (mmWave) Access Point (mmAP) for use in a mobile communication system that includes a plurality of Base Stations (BSs) capable of communicating with a plurality of Mobile Stations (MSs), the mmAP comprising:
a mmWave band transceiver configured to communicate in the mmWave band, the mmWave band transceiver comprising an antenna array, a receiver, and a transmitter that operate in the mmWave band;
a controller configured to control the mmWave band transceiver to communicate with an MS; and
a cellular band transceiver configured to communicate in a cellular band, wherein, when performing communication with the MS via the mmWave band, the controller further is configured to control the cellular band transceiver to communicate with a BS, and
wherein the controller further relays signals from the BS to the MS and from the MS to the BS,
wherein at least one control channel is communicated in the cellular band and at least one data packet is communicated in the mmWave band,
wherein the mmWave band transceiver is configured to use beamforming to communicate the at least one data packet,
wherein the at least one control channel includes a packet data control channel, and
wherein the mmAP is one of: a Relay Station (RS) or a femto BS.

2. A Base Station (BS) for use in a mobile communication system that includes a plurality of BSs capable of communicating with a plurality of Mobile Stations (MSs), the BS comprising:
a cellular band transceiver configured to communicate with an MS in a cellular band, the cellular band transceiver comprising an antenna system, a receiver, and a transmitter which operate in the cellular band;
a millimeter wave (mmWave) band transceiver configured to communicate with at least one other BS in the mmWave band, the mmWave band transceiver comprising an antenna system array, a receiver, and a transmitter which operate in the mmWave band; and
a controller configured to control both the cellular band transceiver and the mmWave band transceiver,
wherein the controller controls the mmWave band transceiver to communicate at least one data packet through a first beamforming in the mmWave band in a first time slot with a first BS and controls the mmWave band transceiver to communicate at least one data packet through a second beamforming in the mmWave band in a second time slot with a second BS.

3. The BS of claim 2 , wherein communication in each of the in a first time slot and the first time slot is bidirectional.

4. The BS of claim 2 , wherein the communication in a first time slot is a communication from the BS to first BS and the communication in the second time slot is a communication from the BS to second BS, and
further wherein a communication in the mmWave band from the first BS to the BS is performed in a third time slot, and a communication in the mmWave band from the second BS to the BS is performed in a fourth time slot.

5. A Base Station (BS) for use in a mobile communication system that includes a plurality of BSs capable of communicating with a plurality of Mobile Stations (MSs), the BS comprising:
a cellular band transceiver configured to communicate with an MS in a cellular band, the cellular band transceiver comprising an antenna system, a receiver, and a transmitter that operate in the cellular band;
a millimeter wave (mmWave) band transceiver configured to communicate with at least one other BS in the mmWave band, the mmWave band transceiver comprising an antenna array, a receiver, and a transmitter that operate in the mmWave band; and
a controller configured to:
control both the cellular band transceiver and the mmWave band transceiver, and
detect network congestion between the BS and a Packet Data Server/Gateway,

wherein, when the controller detects network congestion, the controller controls the mmWave band transceiver to communicate at least one data packet through beamforming in the mmWave band with another BS that would result in less congestion between the BS and the Packet Data Server/Gateway.
