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; 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.
