Abstract: This disclosure relates to methods for providing unsolicited unavailability announcements to manage the co-existence of Wi-Fi and other technologies (such as Bluetooth) and to manage infrastructure and peer-to-peer connections in a wireless communication system. A wireless device may establish multiple wireless connections on a set of radio resources. The wireless device may transmit an unsolicited unavailability announcement frame, which may include information indicating a time period of future unavailability for the wireless device on the set of radio resources. Such an unsolicited unavailability announcement frame may also include information regarding the device's current availability, for example during which the device plans to initiate a transmit opportunity.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing request to send (RTS) and clear to transmit (CTS) frames and transmission rules for the RTS and CTS frame. For example, some aspects relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive, using the transceiver, a request to send (RTS) frame from the second electronic device and determine, using the received RTS frame, a format for a clear to send (CTS) frame to use in response to the RTS frame. The one or more processors further transmit, using the transceiver, the CTS frame based on the determined format on at least one sub-channel on which the RTS frame was received and that the at least one sub-channel is idle.

Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

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 of this disclosure include apparatuses and methods for implementing a target wake time (TWT) technique for multicast communication. For example, some embodiments relate to a method including configuring a target wake time (TWT) process for delivering one or more multicast packets to a group of electronic devices. The method further includes determining that a service period associated with the TWT process has started and transmitting, in accordance with the TWT process, the one or more multicast packets during the service period, where the one or more transmitted multicast packets are addressed to the group of electronic devices.

Abstract: Techniques are directed toward secure scrambling. An example method includes receiving, by a first communication device a physical layer protocol data unit (PPDU) frame from a second communication device. The first communication device can determine a PPDU frame type based at least in part on a preamble of the PPDU frame. The first communication device can apply a PPDU frame type-based key and a determined service field value to implement a descrambling process for a medium access control (MAC) header of the PPDU frame. The first communication device can descramble a payload based at least in part on de-obfuscating the MAC header. The first communication device selecting a scrambler seed for scrambling an acknowledgement (ACK) message. The first communication device scrambling the ACK message based on the selected scrambler seed.

Abstract: Techniques are provided for medium access control header obfuscation. One example method includes a first device encrypting a data payload using a first encryption algorithm. The first device can encrypt a field of a medium access control (MAC) header using a second encryption algorithm, different from the first encryption algorithm. The first device can generate a data frame comprising the encrypted MAC header field and the encrypted payload. The first device can transmit the data frame to a second communication device.
