1. An apparatus, comprisinga first wireless communications device containing a radio, a processor, and a memory, the first wireless communications device configured to:
- transmit, to a second wireless communications device, a request to perform antenna training with the second wireless communications device, the request containing a first information element with a first field indicating the request, wherein the first information element includes a third field to indicate a quantity of training sequences and a fourth field to indicate a length of the training sequences;
receive, from the second wireless communications device, a response to the request, the response containing a second information element with a second field indicating agreement to perform the antenna training; and
perform two-way antenna training with the second wireless communications device, the two way antenna training comprising;
transmission of a predetermined training sequences to the second communications device;
reception, from the second communications device, of a feedback associated with a quality of the transmission of the predetermined training sequences; and
based at least in part on the feedback received from the second communications device, determination of antenna parameters for subsequent directional communications with the second device.
