    Abstract: Methods and apparatuses for privacy enhancement are provided herein. A method performed by a station, STA (201), may include transmitting, to an access point, AP (202), a first frame including information indicating that the STA (201) will use an over-the-air medium access control, otaMAC, address for a frame sent to the AP (202). The method may further include generating (210) a second frame for transmission to the AP (202) including a network MAC, nMAC, address of the STA (201), encrypting (211) the generated second frame, and replacing (212) the nMAC address with an otaMAC address either during the encryption or after the encryption. The method may further include transmitting (213) the encrypted second frame, including the otaMAC, to the AP (202), such that the AP (202) may replace (214) the otaMAC address with the nMAC address and decrypt (215) the second frame for forwarding via a distribution system, DS (203).

    Abstract: Methods and apparatuses are described herein for increasing reliability in IEEE 802.11 networks. A first station (STA) may generate a set of configurations that meets reliability requirements of a traffic flow associated with a frame. Each of the set of configurations may comprise a number of replications of the frame, a channel bandwidth, and a modulation and coding scheme (MCS). The first STA may transmit, to a second STA, a plurality of request to send (RTS) frames over a plurality of channels The first STA may receive, from the second STA, a plurality of clear to send (CTS) frames indicating whether the plurality of channels are available. The first STA may then select, based on the number of available channels, a first configuration from the set of configurations. The first STA may transmit, based on the first configuration, a plurality of copies of the frame simultaneously over the available channels.

    Abstract: Service information (e.g., enhanced broadcast service (eBCS) information) may be distributed. Service (e.g., eBCS) capabilities may be advertised (e.g., by an access point (AP)), for example, by broadcasting a public action frame. A public action frame may include per-service information. A public action frame may be transmitted on a per service basis. A public action frame may combine authentication information and service information. Enhanced broadcast service origin authentication may be performed on a per service basis (e.g., using origin authentication information to authenticate broadcast data frames for a consumed service). Origin authentication information may be common to frames associated with different services. Services may be consumed without querying a service originating device. Stations (e.g., with and without association with an AP) may report consumption or usage of services. Reporting may be unsolicited or solicited (e.g., in response to a request from an AP).
