Path selection for fine timing measurement protocol

An apparatus for wireless communication, the apparatus comprising:

• a first interface configured to obtain a first request frame including an indication to use a first path with a second apparatus for communicating at least one first field of a first measurement frame, the first path with the second apparatus different from a second path with the second apparatus;
• a processing system configured to:
• identify, based on beamforming training with the second apparatus, a first set of antenna settings corresponding to the first path with the second apparatus and a second set of antenna settings corresponding to the second path with the second apparatus, and
• generate, based on the first request frame, the first measurement frame including the at least one first field in a first portion of the first measurement frame and including one or more second fields in a second portion of the first measurement frame, wherein the one or more second fields of the first measurement frame include information indicating at least one timing measurement;
• and
• a second interface configured to output the first measurement frame for transmission to the second apparatus via the first set of antenna settings for transmitting the first portion including the at least one first field of the first measurement frame over the first path and via the second set of antenna settings for transmitting the second portion including the one or more second fields of the first measurement frame over the second path.

A wireless node for wireless communication, comprising:

• a processing system configured to:
• 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 that is different from a second path with the second apparatus corresponding to the second set of antenna settings, and
• generate a first request frame including an indication to use the first path for at least one first field of a first measurement frame;
• a transmitter configured to transmit the first request frame to the second apparatus;
• and
• a receiver configured to receive, from the second apparatus, the first measurement frame via the first set of antenna settings for the at least one first field in a first portion of the first measurement frame transmitted over the first path and via the second set of antenna settings for one or more second fields in a second portion of the first measurement frame transmitted over the second path,
• wherein the one or more second fields of the first measurement frame include information indicating at least one timing measurement.
