Abstract: Certain aspects of the present disclosure provide methods and apparatus for enhancing a beamforming training procedure. For example, according to certain aspects, devices may exchange information regarding the number of beamforming transmit sectors each device plans to use for both partial and full sector sweeps, as well as the number of receive antennas. The devices may also exchange timing information used to synchronize when the devices start to perform the partial and full sector sweeps, after detecting a lost link.

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: Various aspects of the disclosure relate to co-existence of millimeter wave (mmW) communication and radar. In some aspects, a device that supports mmW communication and radar operations may determine whether or when to conduct radar operations based on information obtained about a nearby mmW network. For example, prior to sending radar signals, the device may monitor for mmW communication signals. As another example, the device may send at least one mmW communication signal to reserve a communication medium for subsequent radar operations. As yet another example, the device may conduct radar operations during idle or allocated time periods defined by the mmW network.
