Abstract: This disclosure provides systems, methods, and apparatuses for implementing changes to Basic Service Set (BSS) parameters of an access point (AP) in a synchronized manner across multiple physical layer (PHY) formats. In some implementations, an AP may enable STAs that use different PHY formats to implement the changes at substantially the same time. For example, the change in BSS may be aligned with a target beacon transmission time (TBTT) of a first PHY format, and the AP may broadcast information, in a second PHY format, pointing to the TBTT of the first PHY format. In some other implementations, the AP may enable the STAs to implement the changes at different times. For example, STAs using a first PHY format may implement the change at a TBTT of the first PHY format, whereas STAs using a second PHY format may implement the change at a TBTT of the second PHY format.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for wireless communications and, more particularly, methods and apparatus for providing channel information for multiband operation. The techniques presented herein may help a device (such as an access point) efficiently advertise availability of support in different frequency bands. The signaling techniques presented herein provide, in some cases, for self-contained signaling with sufficient information for a receiving device to efficiently establish operating links in one or more other bands. For example, by providing primary channel width and center channel frequency segments, a receiving device may be able to establish an operating link on another band without lengthy scanning to discover such channels.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication in a neighbor aware network (NAN). In one aspect, a first device of a wireless network (such as a NAN), in response to detecting a low power condition, may transmit a beacon including a power indicator. Other devices of the NAN may process the beacon and determine whether to assume a role of master or non-master sync in the NAN based on the power indicator. For example, a second device of the NAN may determine, based on power information of the second device, to assume the role of master or non-master sync in the NAN. To assume the role of master (or non-master sync), the second device may transmit a second beacon that includes a modified rank value.
