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.

Abstract: Devices and methods for wireless communication are disclosed. A method includes a wireless station receiving a first packet that includes a first media payload and a first media timestamp from a second device. The method includes the station capturing a time of arrival (TO A) timestamp in response to receiving the first packet from the second device. The TOA timestamp is sampled using a device clock of the station. The method includes the station receiving a second packet that includes a second media payload and a second media timestamp from the second device. A time of departure (TOD) timestamp associated with a transmission time of the first packet is embedded in the second packet. The TOD timestamp is sampled using a system clock of the second device. The method includes the station synchronizing its device clock to the system clock of the second device based on the TOA and TOD timestamps..

Abstract: Certain aspects of the present disclosure provide methods and apparatus for polling for data by a wireless device. Certain aspects of the present disclosure providing a method performed by the wireless device. The method generally includes receiving a polling frame from at least one wireless device. The polling frame can include an indication of a service period during which the access point may deliver multiple protocol data units (PDUs) to the wireless device in response to the polling frame. The indication of the service period is provided as a value relative to a local clock synchronized between the wireless device and the access point. The method generally also includes transmitting the multiple PDUs to the wireless device during the service period, in response to the polling frame. The access point can receive the polling frame and transmit the multiple PDUs during the service period, in response to the polling frame.

Abstract: A method and apparatus for broadcasting short interframe space information to aid in determining a round trip time are provided. The round trip time is used as an aid in locating nodes within a WiFi or WLAN network. The method begins with capturing a time of transmission of a frame by a transmitting station. The receiving station then captures the time of arrival of the frame just sent by the transmitting station. The receiving station replies with a received frame message and the time of departure is captured. The transmitting station then captures the time of arrival of the received frame message. The captured arrival and departure times of the frame and the received frame message allow the round trip time to be computed. The RTT may then be included as part of a network message.

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.
