Abstract: This disclosure describes systems, methods, and devices related to dynamic channel bonding and multi-band aggregation. A device may determine a plurality of aggregated medium access control (MAC) protocol data unit (A-MPDU) subframes to send to a station device including a first A-MPDU subframe and a second A-MPDU subframe. The device may determine a quiet period between the first A-MPDU subframe and the second A-MPDU subframe. The device may cause to send the plurality of A-MPDU subframes to the station device on a first channel. The device may determine a status of a second channel during the quiet period. The device may cause to send the second A-MPDU subframe to the station device using a multi-band transmission on the first channel and the second channel.

Abstract: This disclosure describes systems, methods, and devices related to enhanced location determination. A device may cause to exchange one or more capabilities information with one or more station devices. The device may cause to assign one or more unassociated identifications (UIDs) to one or more unassociated station devices of the one or more station devices to participate in location determination of the one or more unassociated station devices. The device may cause to send a trigger frame comprising at least one of the one or more UIDs; wherein the trigger frame contains one or more resource assignments. The device may identify one or more sounding information from at least one of the one or more station devices.

Abstract: Simultaneous dual band operation (2.4 and 5 GHz) is common in APs on the market today, and tri-band devices are expected in the market soon. Link aggregation can also be applicable to multiple air interfaces in the same band (for instance 2 independent IEEE 802.11ac/ax air interfaces at 5 GHz on 2 different 80 MHz channels). One exemplary aspect provides technology that enables significantly higher throughput and/or higher reliability for two stations (STAs) or a STA and the access point (AP) when the devices support simultaneous multi-band operation.

Abstract: Embodiments of an access point (AP), station (STA) and method for channel access are generally described herein. The AP may contend for access to a channel. The contention may be performed in accordance with an omni-directional enhanced distributed channel access function (EDCAF) for transmission within an omni-directional pattern. The contention may be further performed in accordance with a directional EDCAF for transmission to a station (STA) in a directional pattern. The AP may determine whether to transmit within the omni-directional pattern based at least partly on an omni-directional backoff parameter. The AP may further determine whether to transmit in the directional pattern based at least partly on a directional backoff parameter.

Abstract: When performing a contention protocol, such as Listen-Before-Talk (LBT), an Long Term Evolution (LTE)-Licensed Assisted Access (LAA) node dynamically adapts the ED threshold used by the LTE-LAA node depending on whether other transmission nodes are detected at the frequency components that are to be used by the LTE-LAA node. In one implementation, the ED threshold value may initially be set to a conservative value, and when other transmissions nodes are not detected, the ED threshold value may be set to a more aggressive value. In another implementation, the ED threshold value may initially be set to a more aggressive value, and only when another transmission node is detected, the ED threshold value may be set to a more conservative value. In yet another possible implementation, the ED threshold value and the transmit power may be proportionally modified, for a particular UE, based on a parameter associated with the UE.

Abstract: For example, an apparatus may include a segment parser to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits, the PPDU to be transmitted in an OFDM transmission over an aggregated bandwidth comprising a first channel in a first frequency band and a second channel in a second frequency band; a first baseband processing block to encode and modulate the first plurality of data bits according to a first OFDM MCS for transmission over the first channel in the first frequency band; and a second baseband block to encode and modulate the second plurality of data bits according to a second OFDM MCS for transmission over the second channel in the second frequency band.

Abstract: This disclosure describes systems, methods, and devices related to enhanced retry count for an uplink (UL) multi-user (MU) transmission. A device may identify a trigger frame received from a first device on a wireless communication channel. The device may determine a quality of service counter associated with an access category. The device may cause to send a frame to the first device based at least in part on the trigger frame. The device may determine an error condition associated with the frame. The device may refrain from incrementing the quality of service counter based on the error condition.

Abstract: Apparatuses, methods, computer readable media for basic service set (BSS) identifications for using non-default spatial reuse parameters. An apparatus including memory configured to store one or more bitmaps including at least one of a spatial reuse (SR) group (SRG) basic service set (BSS) color bitmap and a SRG Partial BSS identification (ID)(BSSID) Bitmap, and processing circuitry configured to: decode an inter-BSS physical layer convergence procedure (PLCP) protocol data unit (PPDU). The processing circuitry may be further configured to determine the inter-BSS PPDU to be a SRG PPDU if: the inter-BSS PPDU comprises a BSS color field and a bit of the SRG BSS color bitmap corresponding to a value of the BSS color field is set; or a BSSID field is identified for the inter-BSS PPDU, and a bit of the SRG Partial BSSID bitmap corresponding to a value of a partial BSSID of the BSSID is set.

Abstract: Embodiments of a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.
