The present disclosure relates to an antenna array arrangement including a plurality of antenna arrays. Each antenna array includes a plurality of antenna elements. At least two of the plurality of antenna arrays are staggered along at least one of a horizontal dimension or a vertical dimension. Adjacent elements of a projection of the antenna elements of the antenna array arrangement onto a horizontal dimension or a vertical dimension have a distance that is in the order of half of a wavelength of a radio signal to be transmitted from the antenna array arrangement.

Array antenna arrangement

In 60 GHz WiGig/IEEE 802.11ad, Orthogonal Frequency Division Multiplexing (OFDM) is used to achieve higher throughput. However, OFDM has one problem of high Peak-to-Average Power Ratio (PAPR) caused by the summing up of the large number of subcarriers. A high PAPR signal degrades the efficiency of power amplifier (PA) and may cause spurious emissions because of the PA non linearity. In order to reduce PAPR, Generalized Frequency Division Multiplexing (GFDM) which has the characteristics of both single carrier and multi carrier transmission has been studied. By introducing GFDM, the number of subcarriers can be decreased while still maintaining a high throughput.

Some demonstrative embodiments include apparatuses, devices, systems and methods of beam tracking For example, an apparatus may include a transmitter to transmit data to a wireless communication device via a first beam direction of a plurality of beam directions, and to transmit one or more pilot signals via one or more other beam directions of the plurality of beam directions; and a receiver to receive from the wireless communication device a feedback indicating a second beam direction of the plurality of beam directions, the second beam direction being one of the one or more other beam directions, wherein the transmitter is to switch to the second beam direction to communicate with the wireless communication device.

Some demonstrative embodiments include apparatuses, devices, systems and methods of beamforming training. For example, an apparatus may include a transmitter, a receiver, and a controller to repeat a beamforming training sequence including a transmit (Tx) mode and a receive (Rx) mode, at the Tx mode the transmitter is to transmit a directional Tx training signal to a wireless communication device, and at the Rx mode the receiver is to be at an omnidirectional Rx state, wherein subsequent to successful receipt of a directional Rx training signal from the wireless communication device at the receiver, the transmitter is to transmit the directional Tx training signal including an Rx beam indication to indicate a beam direction of the Rx training signal.
