摘要： In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.

摘要： Embodiments of a STA configured for proximity detection by multiple WLAN link tracking are disclosed herein. In some embodiments, the STA performs WLAN sensing using two or more WLAN links with one or more other STAs to track a channel state of each link and performs motion detection based on the tracked channel state of each WLAN link to detect motion in any of the WLAN links. If motion is detected in at least some of the WLAN links, the STA may perform proximity detection to indicate proximity by combining results of the WLAN sensing for each link to determine whether the motion is proximate to the STA or proximate to one of the other STAs.

摘要： Apparatuses, methods, and computer readable media for assignment of secondary millimeter wave channels. An apparatus of a station (STA) is disclosed that includes processing circuitry configured to decode a basic service set (BSS) operating channels field and a primary channel field from an access point (AP) or personal basic service set control point (PCP), wherein the BSS operating channels field is a bitmap that indicates which 2.16 GHz channels of a plurality of 2.16 GHz channels are permitted to be used for transmissions in the BSS, and wherein the primary channel field indicates a 2.16 GHz channel of the plurality of 2.16 GHz channels that is a primary channel of the BSS. The processing circuitry may be further configured to determine the primary channel, a secondary channel, a secondary1 channel, and a secondary2 channel based on the BSS operating channels field and the primary channel field.

摘要： This disclosure describes systems, methods, and devices related to enhanced multiple-input multiple-output (MIMO) beam refinement protocol (BRP) transmit sector sweep (TXSS). A device may establish a first communication link using a first antenna transmit chain of one or more transmit chains of the initiator, wherein the one or more antenna transmit chains further comprise a second antenna transmit chain. The device may initiate a MIMO BRP TXSS over the one or more antenna transmit chains. The device may map a single space-time stream over the one or more antenna transmit chains. The device may cause to send, to a responder device, an enhanced directional multi-gigabit (EDMG) frame using spatial expansion based on the mapping of the single space-time stream. The device may identify a feedback frame from the responder device. The device may determine one or more antenna weight vectors (AWVs) to use in a MIMO phase of the MIMO beamforming training based on the feedback frame.
