    Abstract: Systems, methods, and devices for multicast communications including access identifiers are described herein. In some aspects, a fixed mapping from a multicast device identifier (e.g., multicast MAC address, multicast IP address) to a multicast access identifier is provided. In some aspects, a device may transmit a request to join a multicast group identified by a multicast access identifier. In some aspects, a device may receive an invitation to join a multicast group identified by a multicast access identifier.

    Abstract: Systems, methods, and devices for compressing block acknowledgment (ACK) frames/packets are described herein. In some aspects, a method of compressing a block acknowledgment frame includes generating an offset value and a portion of a bitmap, the offset value indicating a location where the portion of the bitmap is located in the bitmap. The method further includes transmitting the offset value and the portion of the bitmap in a compressed block acknowledgment frame.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for multiuser transmission during a grant to utilize unused portion of a transmit opportunity (TXOP) that is assigned to an initiator device. A responder device may receive, from an initiator device, at least one grant to utilize unused portion of the TXOP. In response to the grant and during the unused portion of the TXOP, The responder device may transmit a first message intended for the to the initiator device, and one or more messages intended for one or more other stations using multi-user transmission schemes. The messages transmitted to stations other than the initiator device may include an indication that the station does not need to respond (e.g., with an acknowledgment) upon receipt of the message.

    Abstract translation: 本公开的某些方面提供了在授权期间利用被分配给发起者设备的发送机会（TXOP）的未使用部分的多用户传输的方法和装置。 应答器设备可以从发起者设备接收至少一个授权以利用TXOP的未使用部分。 响应于该授权以及TXOP的未使用部分期间，应答器设备可以使用多用户传输方案向一个或多个其他站发送旨在用于发起者设备的第一消息和一个或多个消息。 发送到发起者设备之外的站的消息可以包括在接收到消息时站不需要响应（例如，通过确认）的指示。

    Abstract: Wireless communications systems and methods related to channel access contention management in a shared radio frequency band are provided. A first wireless communication device performs, during a first time period, a first clear channel assessment (CCA) in a shared radio frequency band based on a first energy detection threshold, wherein performing the first CCA comprises obtaining at least one signal energy measurement. The first wireless communication device then performs, during a second time period subsequent to the first time period, a second CCA in the shared radio frequency band based on a second energy detection threshold, the second energy detection threshold being based on the at least one signal energy measurement. The wireless communication device then transmits, to a second wireless communication device in the shared radio frequency band based on the second CCA, a communication signal.
