1. An apparatus, comprising: a memory; and logic, at least a portion of which is comprised in circuitry coupled to the memory, the logic to: identify a preferred single-input single-output (SISO) antenna array weight vector (AWV) set for a wireless communication device comprising a first transmit (TX) antenna array and a second TX antenna array, the preferred SISO AWV set to comprise: a preferred AWV v 11 with respect to SISO transmission by the first TX antenna array to a first receive (RX) antenna array of the remote device; a preferred AWV v 12 with respect to SISO transmission by the first TX antenna array to a second RX antenna array of the remote device; a preferred AWV v 21 with respect to SISO transmission by the second TX antenna array to the first RX antenna array of the remote device; and a preferred AWV v 22 with respect to SISO transmission by the second TX antenna array to the second RX antenna array of the remote device; and determine a preferred multiple-input multiple-output (MIMO) AWV pair for the wireless communication device based on the preferred SISO AWV set according to a MIMO AWV selection procedure, the preferred MIMO AWV pair to comprise: a first MIMO AWV comprising an AWV for application to the first TX antenna array in conjunction with a MIMO transmission to a remote device and; a second MIMO AWV comprising an AWV for application to the second TX antenna array in conjunction with the MIMO transmission to the remote device.
