    Abstract: Aspects of the present disclosure provide techniques for efficient ranging, for example, in a neighbor aware network (NAN). According to certain aspects, an apparatus for wireless communications is provided. The apparatus generally includes a processing system configured to determine a period that at least one second apparatus is scheduled to be awake, generate a first frame for transmission to the second apparatus during the period, determine ranging information based on a time difference between transmission of the first frame and receipt of a second frame in response to the first frame, and generate a third frame including the ranging information; a transmit interface configured to output the first and third frames for transmission; and a receive interface configured to obtain the second frame. By exchanging ranging information in already scheduled wake-up periods and in existing frame, power consumption and signaling overhead may be reduced.

    Abstract: A method includes generating a paging message at a first device of a data link group of a neighbor aware network (NAN). The paging message includes a paged device list. The paged device list identifies a subset of devices of the data link group, the subset of devices scheduled to receive data from the first device during a transmission window. The paging message includes a receiver address field having a particular receiver address value. The method also includes transmitting, during the paging window, the paging message from to at least one device of the data link group other than the first device.

    Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a null data packet (NDP) on a plurality of subcarriers, and the STA may generate a channel state information (CSI) matrix for each subcarrier of the plurality of subcarriers. After generating a CSI matrix for a subcarrier, such as at least one subcarrier, the STA may scale each value in the CSI matrix using a power-of-two value to minimize complexity. Specifically, instead of scaling each value in the CSI matrix to a value between zero and one using divisions (for example, which may be computationally expensive), the STA may use shifting to scale each value in the CSI matrix. The STA may then quantize the scaled values in the CSI matrix for reporting, and the STA may transmit the quantized, scaled values in the CSI matrix in a CSI report.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may detect at least one distance between the transmitter and a receiver. The transmitter may transmit, to the receiver, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Similarly, in some aspects, a receiver may detect at least one distance between the receiver and a transmitter. The receiver may receive, from the transmitter, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Numerous other aspects are described.

    CPC classification number: H04W52/0258

    Abstract: Aspects relate to signaling the parameters to be used for a communication schedule such as a target wake time (TWT) schedule. For example, a first wireless communication device (e.g., an access point or a peer station) may determine (e.g., specify or negotiate) the parameters for at least one TWT schedule and transmit a broadcast management frame (e.g., a beacon) that includes these parameters. A second wireless communication device (e.g., station) that receives the broadcast management frame may, based on the received parameters for one TWT schedule or the received parameters for multiple TWT schedules, elect to transmit during a transmission opportunity (TXOP) that is defined to not cross at least one boundary of a period of time indicated by the parameters.

    Abstract: This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.

    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.
