摘要： An access point (AP) station (STA) (AP STA) that is part of an AP multi-link device (MLD) may be configured as a reporting AP may encode a BSS Transition Management (BTM) request frame for transmission to one or more associated non-AP stations (STAs). The BTM request frame may include a neighbor report element encoded to include information about one or more neighbor APs. The neighbor report element may indicate whether the one or more neighbor APs identified in the neighbor report element are part of an AP MLD and, when a neighbor AP is indicated to be part of an AP MLD whether the reporting AP is part of the indicated AP MLD. The AP STA may decode a reassociation frame from one of the non-AP STAs for transition from one of the AP STAs of the AP MLD to one of the neighbor APs.

摘要： Methods, computer readable media, and apparatus for determining a receive (Rx) number of spatial streams (NSS) for different bandwidths (BWs) and modulation and control schemes (MCSs) are disclosed. An apparatus is disclosed comprising processing circuitry configured to decode a supported HE-MCS and a NSS set field, the supported HE-MSC and NSS set field received from an high-efficiency (HE) station. The processing circuitry may be further configured to determine a first maximum value of N receive (Rx) SS for a MCS and a bandwidth (BW), where the first maximum value of N Rx SS is equal to a largest number of Rx SS that supports the MCS for the BW as indicated by the supported HE-MCS and NSS set field; and, determine additional maximum values based on an operating mode (OM) notification frame, and a value of an OM control (OMC) field. Signaling for BW in 6 GHz is disclosed.

摘要： Embodiments of a LP-WUR (low-power wake-up radio) wake-up packet acknowledgement procedure are generally described herein. A first wireless device encodes for transmission of a wake-up packet of a LP-WUR to a second wireless device, the wake-up packet to wake up a WLAN (wireless local area network) radio of the second wireless device. Upon decoding a response frame from the second wireless device received during a predefined time period: the first wireless device encodes for transmission of a data packet to the WLAN radio of the second wireless device. Upon failing to receive the response frame from the second wireless device during the predefined time period: the first wireless device encodes for retransmission of the wake-up packet to the second wireless device.

摘要： Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.

摘要： Embodiments of an access point (AP), station (STA) and method for link aggregation are generally described herein. An aggregated link for multiple channels may be established. The link may be aggregated at an upper medium access control (MAC) entity, which may communicate with multiple lower MAC entities for the channels. The upper MAC entity may assign packet numbers (PNs) to a sequence of MAC service data units (MSDUs) for the aggregated link and may allocate the MSDUs to the channels. The PNs may enable reordering at a receiving entity. The lower MAC entities may assign sequence numbers (SNs) to MAC protocol data units (MPDUs). The SNs may enable acknowledgement at a receiving entity. The MPDUs may include the SNs and the corresponding PNs.

摘要： Apparatuses, methods, and computer readable media for setting parameters for joint overlapping basic service set packet detect level and transmit power. An apparatus is disclosed comprising processing circuitry configured to: determine an overlapping basic service set (OBSS) power detect (PD)(OBSS-PD) and a transmit power (TXP) based on first parameters, and if the wireless device has not received a frame from an OBSS master station that does not belong to a same management domain as the wireless device, determine the OBSS-PD and TXP based on second parameters. The second parameters may permit the wireless device to set the OBSS-PD to a higher value without lowering the TXP. The first parameters require that OBSS-PD and TXP be determined based on a minimum OBSS-PD and a maximum TXP, and require the OBSS-PD to be lowered if the TX power is raised.

The wireless communication device may include hardware processing circuitry configured to: determine to adapt the channel contention, and configured to adapt the channel contention settings by changing a level of a clear channel assessment (CCA) and adapting at least one additional channel contention setting. The hardware processing circuitry may be configured to adapt the channel contention settings by raising a level of the clear channel assessment (CCA) and by decreasing a power used to transmit, raising a back-off time, or modifying a portion of or parameter to a distributed coordination function (DCF). The hardware processing circuitry may be configured to adapt the channel contention settings by decreasing the clear channel assessment (CCA) and increasing a power used to transmit or decreasing an amount of time to wait after a CCA determines the channel is free.

摘要： A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

摘要： A physical layer protocol data unit (PPDU) may include legacy preamble fields followed by a universal signal field (U-SIG). For an extended range (ER) transmission, the U-SIG is encoded to indicate via a bit whether the PPDU is an ER PPDU or a non-ER PPDU. When the U-SIG is encoded to indicate that the PPDU is an ER PPDU, the PPDU may include ER preamble fields following the U-SIG and an ER data field following the ER preamble fields. The ER preamble fields may comprise pre-ER modulated fields followed by ER modulated fields. The pre-ER modulate fields may comprise an ER short training field (ER-STF) followed by an ER long training field (ER-LTF) followed by an ER signal field (ER-SIG). The ER modulated fields may comprise at least the ER data field.
