Abstract: Some aspects of this disclosure include apparatuses and methods for implementing power consumption mitigation techniques for downlink transmission of a high priority payload in wireless communication networks. For example, an electronic device includes a transceiver and a processor. The processor is configured to receive, using the transceiver and from a second electronic device, a preamble associated with a first payload. The processor is further configured to determine, based at least on the preamble, that a second payload is to be received. The processor is further configured to receive, from the second electronic device, an overload marker symbol (OMS) and determine, based at least on the OMS, whether the second payload is to be received following the OMS. The processor is further configured to transition the transceiver to, or maintain the transceiver in, an awake state in response to determining that the second payload is to be received following the OMS.

Abstract: The subject disclosure provides systems and methods for improved medium access for wireless communication. A wireless access point, on contending for and gaining medium access, may share a time and/or bandwidth channel resource with one or more other wireless access points and/or one or more client devices. The wireless access point can efficiently share the channel resource using buffer status information computed by the wireless access point and/or additional buffer status information computed by the one or more other wireless access points. In one or more implementations, latency information for buffered data can be provided from a client device to a wireless access point and/or from a satellite wireless access point to a control wireless access point.

Abstract: Some aspects of this disclosure are directed to implementing a discovery procedure including one or more of single channel publish phases, multi-channel publish phases, and single channel subscribe phases. For example, a method includes determining, by a publisher device, a first time period for a single channel publish phase and determining, by the publisher device, a second time period for a multi-channel publish phase. The method further includes transmitting, by the publisher device, one or more frames during at least one of the first time period of the single channel publish phase or the second time period of the multi-channel publish phase. The method further includes receiving, by the publisher device, a service specific message from a subscriber device during the at least one of the first time period of the single channel publish phase or the second time period of the multi-channel publish phase.

Abstract: Methods and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing a hibernation mode for multi-link wireless communication networks such as a wireless local area network (WLAN). For example, some aspects relate to a multi-link device (MLD) including a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link. The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.

Abstract: Methods and apparatus to support scheduled access control for an electronic lock are described herein. An initiating central wireless device obtains an ephemeral identity resolving key (IRK) to use in resolving an ephemeral resolvable private address (RPA) of a peripheral wireless device. The initiating central wireless device can subsequently connect securely to the peripheral wireless device in order to unlock an electronic lock controlled by the peripheral wireless device to gain access during a scheduled time period. The ephemeral IRK and ephemeral RPA can be used for a limited period of time and/or for a predetermined number of usages during the scheduled time period.

Abstract: Some embodiments include an apparatus, method, and computer program product for infrastructure and peer-to-peer (P2P) medium access sharing. Some embodiments enable an access point (AP) to assist associated stations (STAs) in accessing a channel. In some embodiments, an AP can receive a request for coordinated transmission for peer-to-peer (P2P) communications, determine a bandwidth available for use during a transmit opportunity (TXOP), and allocate, from the bandwidth, a first subset of one or more channels for infrastructure communications and a second subset of one or more channels for the P2P communications responsive to the request. The AP can transmit to a STA, a first signal corresponding to the second subset of one or more channels for the P2P communications, indicating that the second subset of one or more channels can be used for P2P communications during the TXOP.

Abstract: A multilink access point may communicate with a legacy device. The multilink access point identifies an attempt, by at least one legacy station, to connect to the access point, determines that the at least one legacy station does not support multilink communications, broadcasts a beacon identifying information for a basic communication link that can be used by the at least one legacy station and associates with the at least one legacy station based at least on information included in the beacon, wherein the at least one legacy station communicates exclusively on the basic communication link with the access point.
