    Abstract: Certain aspects of the present disclosure provide methods and apparatus for multi user bar protocols and frames. According to certain aspects, an apparatus is provided for wireless communications. The apparatus generally includes a processing system configured to determine that a plurality of devices have a first capability and generate a multi-user (MU) packet that solicits an immediate response from a plurality of the devices, wherein the immediate response comprises an acknowledgment (ACK) or block ACK (BA) and an interface configured to output the MU packet for transmission.

    Abstract: Certain aspects of the present disclosure provide techniques for communicating time synchronized data between a client and a server. An example method generally includes synchronizing, by a client, a clock of the client with a clock source. The method also includes transmitting, from the client to a server, at an application level, information indicating the clock source, a cell identifier of a serving cell of the client, and accuracy of the clock source as a time value. The method further includes transmitting, from the client to the server, a message including data and a timestamp correlated to an event associated with the data based on the clock. The method also includes in response to the message, receiving, by the client from the server, generated data.

    Abstract: An explicit indication is provided regarding whether information was subjected to interference during transmission. For example, a receiver can monitor received packets and determine whether any of data units in a given received packet were subjected to interference during transmission. If so, the receiver can send an indication to the transmitter to inform the transmitter of the interference. This indication enables the transmitter to distinguish between packet loss that occurred as a result of channel fade and packet loss that occurred as a result of interference. Consequently, the transmitter is able to invoke different actions depending on whether the packet loss is due to channel fade or interference.

    Abstract translation: 提供关于在传输期间信息是否受到干扰的明确指示。 例如，接收机可以监视所接收的分组，并且确定给定的接收分组中的任何一个数据单元是否在传输期间受到干扰。 如果是这样，接收机可以向发射机发送指示以通知发射机的干扰。 该指示使得发射机能够区分由于干扰而导致的由于信道衰落和分组丢失而导致的分组丢失。 因此，发射机能够根据信道衰落或干扰造成分组丢失来调用不同的动作。

    Abstract: Certain aspects of the present disclosure relate generally to wireless communications, and more specifically to systems, methods, and devices for staggered primary channel selection for WiFi. According to certain aspects, a method for wireless communications is provided. The method may be performed, for example, by an access point (AP). The method generally includes obtaining information regarding neighbor basic service sets (BSSs), selecting a primary channel based on the obtained information, and output for transmission a message signaling an intention to communicate using the selected primary channel.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for extending range and delay spread in 2.4 and 5 GHz bands, and potentially frequency multiplexing users. An apparatus is provided for wireless communications. The apparatus generally includes a processing system configured to generate a packet comprising a first preamble decodable by a first type of device and a second type of device, a second preamble that is decodable by the second type of device, but not the first type of device, and data and a transmitter configured to transmit the packet, wherein the first preamble is transmitted using a first channel bandwidth and the second preamble and data are transmitted using only a portion of the first channel bandwidth.
