1. A transmitting station (STA) to support directional wireless links with multiple receiving STAs, the STAs to operate in a millimeter-wave (mmWave) wireless network, the transmitting STA comprising: hardware processing circuitry; and memory, to:
for each of the multiple receiving STAs:
configure transmitter circuitry to transmit a first packet over a directional wireless link between the transmitting STA and the receiving STA, the first packet including a data portion, a receive training sequence, and a transmit training sequence that occupy different portions of the first packet, the transmission of the first packet over the directional wireless link including transmission of the data portion of the first packet according to a current transmit antenna direction associated with the directional wireless link;
configure receiver circuitry to receive transmit antenna performance metrics from the receiving STA associated with the transmission of the first packet over the directional wireless link between the transmitting STA and the receiving STA;
determine an updated transmit antenna direction for the directional wireless link between the transmitting STA and the receiving STA based at least partly on the transmit antenna performance metrics received from the receiving STA; and
configure the transmitter circuitry to transmit to the receiving STA a second packet that includes a data portion, a receive training sequence, and a transmit training sequence that occupy different portions of the second packet, wherein the transmission of the second packet includes transmission of the data portion of the second packet according to the updated transmit antenna direction.
