Abstract: Certain aspects of the present disclosure provide techniques that may help reduce sector sweep time. In some cases, the techniques involve generating frames for transmission during a sector sweep procedure, each frame including an address field being determined based on at least one of a transmitter address of the apparatus or a receiver address of an intended recipient of the generated frames and having fewer bits than at least one of the transmitter address or the receiver address. In some cases, the techniques involve using different frame formats for initiator and responder frames transmitted during the sector sweep procedure.

Abstract: Certain aspects of the present disclosure generally relate to beamforming training for a sector corresponding to a line of sight (LOS). For example, certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes an interface for obtaining a plurality of frames from a wireless node during a sector sweep procedure, and a processing system configured to select a frame of the plurality of frames as corresponding to a line of sight (LOS) between the apparatus and the wireless node based on a relative time of flight (RTOF) of the frame, and perform beamforming using the selected frame.

Abstract: This disclosure provides wireless communication methods, components, devices and systems for link recovery in wireless communication networks. Some aspects more specifically relate to the recovery of lost wireless communication links for which initial link establishment has been aided by communications over anchor links of different frequency bands than those of the lost wireless communication links. According to some aspects, a recovery mechanism can be implemented that enables involved devices to recover such “extension” links using communications over their associated frequency bands, without needing to revert to communication over their corresponding anchor links. In some examples, such a recovery mechanism can be implemented to enable recovery of a millimeter wave (mmWave) extension link of a non-standalone mmWave basic service set (BSS) without needing to revert to communication over a sub-7 GHz anchor link.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating frames with dual mode channel estimation fields (CEFs) that may accommodate devices with different processing capabilities. In some examples, a frame that is generated comprises a first portion for transmission on separate channels, and a second portion for transmission using channel bonding. The second portion has a training field including first complementary sequences, a first channel estimation field (CEF) including second complementary sequences, and a second CEF including one of the first complementary sequences of the training field and a subset of the second complementary sequences of the first CEF.
