Abstract: A method of communication includes generating a control message at a particular device. The control message indicates availability of data to be sent by the particular device. The data includes first data corresponding to a first access category. The method also includes, subsequent to determining that transmission of the control message is to be delayed, determining a first delay based on the first access category. The method further includes sending the control message from the particular device upon expiration of a delay period. The delay period is based on the first delay.

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: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

Abstract: Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes initiating a contention based process for transmitting a synchronization message during a discovery time interval of a discovery time period. The synchronization message includes a first timestamp of the wireless communication apparatus. The method further includes selectively transmitting the synchronization message based on a master preference value of the wireless communication apparatus.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be configured to transmit a request message to a plurality of access points. The request message may include an address reserved for at least one of an access point feature, an access point service, or an access point vendor. The apparatus may be configured to receive a response message from at least one access point of the plurality of access points. The response message may indicate that the at least one access point has the access point feature, is associated with the access point service, or is associated with the access point vendor.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operating in a television white space (TVWS) network. One example method generally includes receiving, at an apparatus, a message with a field indicating a current version of an unused frequency spectrum map (e.g., a white space map (WSM)), the unused frequency spectrum map indicating channels usable for wireless communications; determining whether the current version of the unused frequency spectrum map is different than a previous version of the unused frequency spectrum map; and using a channel for wireless communications based on the determination. Another example method generally includes accessing a database of available channels for a current location of an apparatus via a neighboring portable or fixed enabling apparatus and enabling one or more portable dependent apparatuses for the wireless communications via one or more of the available channels.
