1. An apparatus of a communication device, comprising:
an antenna array; and
baseband circuitry coupled to the antenna array and configured to:
perform a transmit sector sweep to determine a transmit direction;
perform a receive sector sweep based on the transmit direction;
using the transmit direction and a receiver direction associated with the receive sector sweep, measure a signal-to-noise ratio at a receiver; and
compute a power allocation for subsequent transmissions based on the signal-to-noise ratio, the subsequent transmissions based on a reduced channel matrix associated with the antenna array.
