Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to protecting control frames with power-related subfields. One example apparatus for wireless communications generally includes a processing system configured to generate a control frame comprising one or more power-related subfields and an integrity check value calculated based, at least in part, on the one or more power-related subfields and a transmitter configured to transmit the control frame. In aspects, a power management (PM) subfield, an end-of-service-period (EOSP) subfield, a more data (MD) subfield, or a traffic identifier (TID) subfield can be added to a group of additional authentication data (AAD) and the integrity check value is calculated based on the group of AAD.

Abstract: Techniques for proving enterprise mode security for relays are disclosed. For example, enterprise mode security based on IEEE 802.1x is provided for relays or other similar devices to extend the coverage of access point hotspots or other similar access point use cases. According to one aspect, a relay incorporates an authentication client associated with an authentication server. According to another aspect, a four address format is employed for tunneling messages via a relay between a station and an access point. According to another aspect, a cryptographic master key associated with an access point and a station is provided to a relay to enable the relay to be an authenticator for the station.

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: Systems and methods for low overhead paging in a wireless communications network are described herein. In some aspects, an apparatus for wireless communication includes a receiver and a processor. The receiver receives a request from a first device. The request indicates a first period of a plurality of periods corresponding to a periodicity for transmitting paging messages. The processor assigns the first device to a group scheduled to receive paging messages at most every first period based on the request and determines a start time for transmitting paging messages to the first device based on schedules for transmitting paging messages to a plurality of other devices. In other aspects, an apparatus for wireless communication includes a processor and memory. The processor derives an information sub-unit from an information unit associated with a paging message, compresses the information sub-unit, and generates a second information unit associated with the method of compression.
