1. A communication system for multiple-in-multiple-out (MIMO) communication with an aerial platform, the communication system comprising:
a service platform comprising a plurality of first antennas in line-of-sight (LoS) MIMO communication with a plurality of second antennas on the aerial platform, a number of the first antennas being greater than a number of the second antennas; and
a controller communicatively coupled to the plurality of first antennas and configured to select a subset of the first antennas and to communicate a plurality of data streams with the aerial platform via the subset of the first antennas that is selected,
wherein the controller selects the subset of the first antennas such that the first antennas of the subset have spacings therebetween based on at least two of information related to an aerial platform orientation relative to the first antennas, information related to a spacing of the second antennas, information related to a slant range, and information related to a frequency of operation.
