摘要： Embodiments of a station (STA), access point (AP) and method for communication in the presence of spatial reuse (SR) transmissions are generally described herein. An STA may determine a received signal strength indicator (RSSI) based on one or more inbound physical layer convergence procedure (PLCP) protocol data units (PPDUs) received from a destination STA. The STA may determine, based at least partly on a comparison between the RSSI and a predetermined threshold, whether SR transmissions by other STAs in the channel are permissible. The SR transmissions may be concurrent to transmissions by the STA within the TXOP in the channel. The STA may transmit a PPDU to the destination STA that includes an SR indicator that indicates whether the SR transmissions are permissible.

摘要： This disclosure describes systems, methods, and devices related to traffic indications for multi-link devices (MLDs). A device may generate a first traffic indication map (TIM) with a first bitmap including a first indication that traffic is to be sent by a first access point (AP) device of the MLD to a first non-AP device of a second MLD using a first communication link. The device may generate a second TIM with a second bitmap including a second indication that no traffic is to be sent by a second AP device of the MLD to a second non-AP device of the second MLD using a second communication link. The device may send, using the first communication link, the beacon, the beacon including the first TIM and the second TIM. The device may send, using the first communication link, a data frame to the first non-AP device of the second MLD.

摘要： Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.

摘要： This disclosure describes systems, methods, and devices related to intra-basic service set (BSS) signaling for multiple access points (APs). A device may determine one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS. The device may include, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs. The device may include, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device. The device may cause to send the first frame a first station device of one or more station devices. The device may cause to send the second frame to a second station device of the one or more station devices.

摘要： A wireless communication device comprises a transceiver configured to communicate information with one or more neighbor devices in accordance with a sync mode of a WiFi communication protocol, and a controller. The controller is configured to monitor for reception of at least one of a response frame or a beacon frame sent by any neighbor device, determine whether to schedule transmission of a service frame, and change operation to a background scan mode when the at least one of the response frame or the beacon frame sent by any neighbor device is undetected for a specified time duration and the transmission of a service frame is unscheduled.

摘要： Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

摘要： An apparatus for a station (STA) is generally described herein. The STA includes a low-power WUR (LP-WUR), a local timing synchronization function (TSF) timer, and processing circuitry. The processing circuitry can decode a signal received from an access point (AP) at the LP-WUR, the signal including a TSF value, the TSF value including a subset of octets of a TSF timer associated with the AP. The STA can synchronize the local TSF timer of the STA with the TSF timer associated with the AP by adjusting a local TSF timer based on a count of a number of octets included in the subset of octets. The LP-WUR can wake up a wireless local area network (WLAN) radio of the STA at a wake-up time based on the local TSF timer. Other methods, apparatuses and systems are also described.
