Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication includes receiving, via a first device, a first wireless message granting permission for the first device to transmit a message during a transmission opportunity, the first wireless message being transmitted to the first device at least partially concurrently with a transmission of at least a portion of a second wireless message addressed to a second device, the first wireless message being received over a first spatial stream and the second wireless message being transmitted over a second spatial stream; and transmitting, via the first device, a third message to a third device during the transmission opportunity at least partially concurrently with a transmission of a fourth message by the second device to the third device.

Abstract: Aspects of the present disclosure provide techniques and apparatus for deferral based on basic service set identification (BSSID) information. According to certain aspects, a method for wireless communications is provided. The method generally includes receiving, on a shared access medium, a packet having at least one deferral-related parameter and deciding whether to defer transmission on the shared access medium based, at least in part, on the deferral-related parameter. Another method may generally include generating a packet comprising at least one deferral-related parameter to be used by another apparatus for deciding whether or not the other apparatus should defer transmitting on a shared access medium and providing the packet to the other apparatus.

Abstract: A particular method includes receiving a first frame from a station at an access point indicating that the station is to enter a power save mode. The method also includes transmitting one or more data frames from the access point to the station. The one or more data frames were buffered for transmission prior to receipt of the first frame. The method further includes transmitting an end of data frame to the station. Another particular method includes transmitting a first frame from the station to the access point indicating that the station is to enter the power save mode. The method also includes refraining from entering the power save mode until an end of data frame is received from the access point.

Abstract: Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication.

Abstract: A particular method includes transmitting a frame from a station to an access point. The frame includes a beacon sequence number related to a configuration of the access point. The method also includes, in response to transmitting the frame, receiving an update frame from the access point. The update frame indicates at least one change in the configuration of the access point.

Abstract: In a particular embodiment, a method includes determining, by a first device, a number of discovery messages received during at least one discovery interval. Based on the number of discovery messages, an estimated number of devices in an ad-hoc network is determined. The method further includes transmitting, during a second discovery interval that is subsequent to the at least one discovery interval, a discovery message. The discovery message indicates the estimated number of devices in the ad-hoc network.
