    Abstract: A method for transmitting a frame includes generating an omni portion of the frame, the omni portion including a non-beamformed long training field and a signal field, the non-beamformed long training field including channel estimation information used to decode the signal field, the non-beamformed long training field configured to be transmitted through one of multiple antennas and multiple streams. The method also includes generating a multi-stream portion of the frame, the multi-stream portion including a data field and a multi-stream long training field, the multi-stream long training field including station-specific decoding information for station-specific data in the data field. The method further includes applying a beamforming indicator to the signal field of the omni portion, and transmitting the frame.

    Abstract: An access point (AP) hashes its SSID/BSSID according to a hashing function H and transmits wirelessly the hashed SSID/BSSID within a physical layer frame/packet to a user station (STA). The hashed SSID/BSSID uniquely identifies the AP. In one embodiment, the hashed SSID/BSSID is transmitted within a SIGNAL field of a preamble with the frame/packet. Upon receipt, the user station recovers the hashed SSID/BSSID and compares it to an expected hashed SSID/BSSID (calculated using the same hashing function H and a desired SSID/BSSID). In response to the comparison, the user station performs one or more actions.

    Abstract translation: 接入点（AP）根据散列函数H对其SSID / BSSID进行散列，并将物理层帧/分组内的散列SSID / BSSID无线发送到用户站（STA）。 散列SSID / BSSID唯一标识AP。 在一个实施例中，散列的SSID / BSSID在具有帧/分组的前同步码的信号字段内发送。 在接收时，用户站恢复散列的SSID / BSSID，并将其与预期散列的SSID / BSSID（使用相同散列函数H和期望的SSID / BSSID计算）进行比较。 响应于比较，用户站执行一个或多个动作。

    Abstract: The present disclosure provides for methods, systems and apparatus related to WLAN enhanced channel map advertisements. An aspect of the disclosure provides for a method for discovering a network. The method includes sending a discovery request to an access point for discovering a network, the discovery request requesting for: available channels of access points within a radio range of the device, one or more access network operators for the available channels, and one or more service providers for the available channels. The method further includes receiving from the access point a response message including one or more lists indicative of: the available channels, the one or more access network operators, and the one or more service providers. In some embodiments, the response message is based on one of: internal data of the access point, and databases indicative access network operators and service providers.
