In one aspect, a method for wireless communication includes generating a clear to send message comprising a specific medium access control address (MAC) identifiable by a first subset of a plurality of wireless devices as instructing not to update an associated network allocation vector according to a duration field in the clear to send message. The specific MAC address is not identifiable by a second subset of the plurality of wireless devices such that the second subset of the plurality of wireless devices are instructed to update an associated network allocation vector according to the duration field. The method further includes transmitting the message, thereby reserving wireless communication access for the first subset of the plurality of wireless devices.

Abstract: A method and apparatus are disclosed to establish and verify a Tunneled Direct Link Setup (TDLS) link between a first wireless device and a second wireless device. In some embodiments, the first wireless device may receive a TDLS setup confirmation message from the second wireless device. Based on the TDLS setup confirmation message, the first wireless device may transmit a TDLS verification message to the second wireless. The TDLS link may be verified when the second wireless device receives the TDLS verification message. In some embodiments, when the TDLS verification message is not received by the second wireless device, a TDLS check message may be sent by the second wireless device to the first wireless device. The first wireless device may transmit a TDLS check complete message based on the TDLS check message. The TDLS link may be verified when the second device receives the TDLS check complete message.

Abstract: Detection and reporting techniques for collisions between transmitters of two different radio access technologies (RATs) transmitting in a shared radio frequency spectrum band is described. The collision may occur following a listen-before-talk procedure but prior to transmission of data, and may not affect the reception of the transmitted data. Collisions may be detected using for example, energy sensing, preamble or ready-to-send (RTS) signal detection, or unsuccessful decoding of all or part of a channel reservation signal. A transmitting device may determine a collision has occurred by detecting an energy level during a preamble transmission is greater than a threshold level or by detecting that an energy level during a transmission gap of a time-domain energy pattern is above a threshold level. A receiving device, such as a user equipment (UE), that detects the collision may report the collision to the transmitter.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently managing groups of stations (STAs) receiving simultaneous transmissions in a multiuser multiple-input multiple-output (MU-MIMO) scheme. One example method generally includes; for a first apparatus in a number of groups of apparatuses, allocating a first spatial stream position for each of at least one first group in the number of the groups; and transmitting a first unicast message to the first apparatus, wherein the first unicast message comprises an indication of the allocated spatial stream position for each of the at least one first group and, for each group in the number of the groups, an indication of a membership status, in the group, of the first apparatus.

Abstract: A particular method includes receiving a power save polling frame from a station at an access point. The method also includes, in response to receiving the power save polling frame, transmitting a frame from the access point to the station indicating whether traffic associated with the station is buffered at the access point. Another particular method includes transmitting a frame from the station to the access point indicating that the station is to enter the power save mode and refraining from entering the power save mode until receipt of an end of data frame. Yet another particular method includes receiving a fetch trigger frame at an access point and refraining from transmitting one or more fetched data frames from the access point until a fetch time has elapsed or a delivery trigger frame is received. The access point is configured to communicate with other stations during the fetch time.
