Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

Abstract: Logic may implement a hierarchical data structure for traffic indication mapping (TIM) and segment the TIM into TIM segment bitmaps to facilitate transmissions for wireless communications devices. The traffic indication provides information as to whether a device associated with an access point (AP) has data buffered by the AP. Logic of the AP may inform devices about the range of devices represented by each of the TIM segments by including a block start and block range or a TIM segment index that can be associated with a range of blocks. Logic may provide at least one page bitmap to devices for the TIM segment bitmaps to provide an indication to the devices as to whether a particular block includes an indication that any client devices have data buffered by the access point.

Abstract: Examples are disclosed for transmitting data via a relay communication links. In some examples, a wireless device may receive a packet having a physical layer convergence protocol (PLCP) header that indicates whether the packet also includes a relay header placed before a media access controller header. The packet may be dropped or the relay header may be decoded based on a determination of whether the PLCP header indicates that the packet includes the relay header. Other examples are described and claimed.

Abstract: An access point station (AP) generates a trigger frame (TF) for transmission to two or more non-AP stations (STAs) or groups of STAs. The trigger frame may allocate resource units (RUs) for a trigger-based (TB) transmission to the two or more STAs. The AP may encode the trigger frame to include a Common Info field followed by one or more Special User Info fields. The Common Info field and the one or more Special User Info fields and may be encoded to solicit (i.e., trigger) a trigger-based (TB) Frequency Aggregated Physical layer Protocol Data Unit (PPDU) (FA-PPDU) that includes more than one PPDU of at least two different physical layer (PHY) types from the two or more STAs or groups of STAs. The different PHY types may include high-efficiency (HE), Extremely High Throughput (EHT), Ultra-High Rate (UHR), and UHR+. Accordingly, an AP can trigger a FA-PPDU that includes TB PPDUs of different PHY types.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

Abstract: This disclosure describes systems, methods, and devices related to multi-link devices (MLDs). A MLD may identify a first security key received from a first access point MLD (A-MLD); identify a second security key received from the first A-MLD; transmit, from a first physical location, a first packet to the first A-MLD, the first packet including the first security key; identify a first subset of N packets, the first subset received from the first A-MLD; transmit, from a second physical location, a second packet to the second A-MLD, the second packet including the second security key; identify a second subset of the N packets, the second subset received from the second A-MLD; determine that a third packet of the N packets was not received; and transmit, to the first A-MLD or the second A-MLD, an indication that the third packet was not received.

Abstract: Embodiments of a non-access point (non-AP) EHT station (EHT STA) configured to operate as part of an STA multi-link logical entity (STA MLLE) comprising the EHT STA and one or more other non-AP EHT STAs are generally described herein. The STA MLLE is configured to be associated with an access point (AP) MLLE (AP MLLE) comprising a plurality of EHT APs. The EHT STA is configured to decode a beacon frame received from the EHT APs of the AP MLLE including a multi-link beacon check element to indicate which of the one or more multiple links has a critical update to its link parameters. When the multi-link beacon check element indicates an update to link parameters for the link between the EHT STA and its associated EHT AP, the EHT STA is to configured obtain the updated link parameters either waking-up at a target beacon transmission time (TBTT) or send a probe request.

Abstract: An apparatus may be configured to perform a time-sensitive communication via a Multi User (MU) Multiple-Input-Multiple-Output (MIMO) (MU-MIMO) transmission. For example, an Access Point (AP) may be configured to transmit MU-MIMO schedule information to schedule an MU-MIMO transmission including a plurality of spatial streams, the plurality of spatial streams including a first spatial stream allocated to a scheduled data transmission of a scheduled wireless communication station (STA), and a second spatial stream allocated as a reserved spatial stream, which is reserved for an unscheduled time-sensitive communication with a time-sensitive STA; and to communicate the scheduled data transmission with the scheduled STA over the first spatial stream.
