Abstract: Certain aspects of the present disclosure provide methods and apparatus for using frames having beamforming training fields with base complementary code sequences that have a longer length than complementary code sequences used in other fields of the frame. The longer length may help perform channel estimation when encountering longer delay spread, for example, due to multipath effects of multiple beams during a beamforming training procedure. The longer length may be based on a lengthening factor which may be signaled, for example, using on or more bits of a preamble portion of the frames.

Abstract: A method and an apparatus for performing beamforming training using time division duplex (TDD) service periods is provided. An initiator device configures slots assigned to a responder device of an existing TDD schedule for the beamforming training. The initiator device transmits one or more packets to trigger an antenna sweep for one or more sectors of a beamforming antenna of the responder device during a first slot of the multiple slots. The first slot is assigned to the responder device for receiving from the initiator device. The responder device performs the antenna sweep for the one or more sectors of the beamforming antenna of the responder device. The responder device transmits to the initiator device an acknowledgement of the antenna sweep in a second slot of the multiple slots assigned to the responder device. The second slot is assigned to the responder device for transmitting to the initiator device.

Abstract: A first apparatus may identify a first set of antenna settings and a second set of antenna settings based on beamforming training with a second apparatus, and the first set of antenna settings may correspond to a first path that is different from a second path with the second apparatus corresponding to the second set of antenna settings. The first apparatus may generate a first request frame including an indication to use the first path for at least one first field of a first measurement frame, and may output the first request frame for transmission to the second apparatus. The first apparatus may obtain, from the second apparatus, a first measurement frame via the first set of antenna settings for reception of at least one first field and via the second set of antenna settings for reception of one or more second fields of the first measurement frame.

Abstract: An apparatus may identify a first set of antenna settings and a second set of antenna settings based on beamforming training with a second apparatus, the first set of antenna settings corresponding to a first path with the second apparatus different from a second path with the second apparatus corresponding to the second set of antenna settings. The apparatus may generate a first frame including an indication to use the first path instead of the second path for at least a portion of a fine timing measurement (FTM) session. The apparatus may transmit the first frame for transmission to the second apparatus. The apparatus may receive, from the second apparatus based on the first set of antenna settings, a plurality of FTM measurement frames associated with the at least the portion of the FTM session.
