Logic to place one or more protocol data units (PDUs) in a transmit queue for transmission. Logic to perform a directional clear channel assessment (CCA) for a first sector of a 60 gigahertz (GHz) link, the directional CCA to determine only if the first sector is busy or idle. Logic to determine the directional CCA indicates idle for the first sector. Logic to cause transmission of the first PDU to the STA via the first sector of the 60 GHz link based on the directional CCA. Logic to receive an acknowledgement (ACK) of receipt of the PDU from the STA. Logic to perform a directional CCA for a second sector of the 60 GHz link. And logic to communicate via the first sector and the second sector independently.
