TECHNICAL FIELD

The present disclosure relates to a wireless communication apparatus and a communication control method.

BACKGROUND ART

Nowadays, as a configuration of a base station system that provides a wireless service, a separated base station having a configuration in which a base band processing unit (BBU; Base Band Unit) that processes a base band signal, and a wireless unit (RRH; Remote Radio Head) that transmits and receives radiowaves to and from antennas are separated has become common. Examples of documents that disclose such a separated base station include Patent Documents 1 and 2.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

In a case where a simple configuration in which a BBU is arranged in a cloud base on a network, and an RRH includes an antenna, an RF circuit, and an AD/DA converter is employed from among configurations of such a separated base station, how a data amount is suppressed becomes important especially in a case where the number of antennas increases.

In view of the foregoing, the present disclosure proposes a wireless communication apparatus and a communication control method that are novel and improved, and can efficiently reduce a data amount between an RRH and a BBU in a configuration of a separated base station in which a BBU is arranged in a cloud base on a network.

Solutions to Problems

According to the present disclosure, a wireless communication apparatus including two-dimensionally-arrayed antenna elements, and an arrangement unit configured to arrange IQ data of signals output from the antenna elements, for each time in a state in which an array of the antenna elements is maintained is provided.

Furthermore, according to the present disclosure, a wireless communication apparatus including two-dimensionally-arrayed antenna element, a compression unit configured to execute compression processing on IQ data of signals output from the antenna elements, and a beam forming unit configured to execute beam forming processing on the IQ data before compression processing is performed by the compression unit is provided.

Furthermore, according to the present disclosure, a communication control method including acquiring IQ data of signals output from two-dimensionally-arrayed antenna elements, and arranging the IQ data for each time in a state in which an array of the antenna elements is maintained is provided.

Furthermore, according to the present disclosure, a communication control method including acquiring IQ data of signals output from two-dimensionally-arrayed antenna elements, executing compression processing on the IQ data, and executing beam forming processing on the IQ data before the compression processing is provided.

Effects of the Invention

As described above, according to the present disclosure, a wireless communication apparatus and a communication control method that are novel and improved, and can efficiently reduce a data amount between an RRH and a BBU in a configuration of a separated base station in which a BBU is arranged in a cloud base on a network can be provided.

Note that the above-described effect is not always limitative, and together with the above-described effect or in place of the above-described effect, any of the effects described in this specification, or other effects recognized from this specification may be caused.
