Abstract: In one aspect, a method performed by an access point in a wireless local area network (WLAN), includes receiving a first ranging request message from a first device and monitoring for a second ranging request message from a second device on a channel of the WLAN. The first ranging request message includes a device identifier of the first device and the second ranging request message includes a device identifier of the second device. In response to receiving the second ranging request message, the access point combines the device identifier of the first device, first timing information associated with the first ranging request message, the device identifier of the second device, and second timing information associated with the second ranging request message into a single ranging response message. The access point then broadcasts the single ranging response message on the channel of the WLAN.

Abstract: Apparatus, methods, and computer-readable media for an error correction technique that identifies transmission errors and corrective actions to maintain a link are disclosed herein. An example method of wireless communications includes receiving a first PDU comprising at least one of a SEQN bit or a packet counter value. The example method includes determining whether a value of the SEQN bit of the received first PDU is an expected SEQN or an unexpected SEQN. The example method includes calculating a MIC of the received first PDU. The example method includes determining whether the received first PDU is a re-transmission of a previous PDU or the received first PDU comprising errors. The example method includes transmitting an ACK or a NACK in response to the determination of whether the first PDU is the re-transmission of the previous PDU or the first PDU comprising errors.

Abstract: A method for wireless communications in a mesh network at a first device is disclosed. The method includes receiving, during a friendship termination procedure, direct forwarding information from a second device and storing the directed forwarding information from the second device. The method also includes terminating the friendship with the second device and establishing a friendship with a third device. The method also includes transmitting the directed forwarding information to the third device.

Abstract: In a wireless communications system, packet error rate may be relatively low (e.g., five percent). Accordingly, receivers may successfully receive a first transmission the majority of the time. However, bandwidth may be used for retransmissions, which may be used relatively infrequently. Because retransmission packets do not necessarily have to be the same as transmission packets, transmission packets may be given more weight than retransmission packets. For example, transmission packets may be encoded with a higher bitrate than retransmission packets. In aspects, a transmitter may send a first transmission packet, including first data encoded with a first bitrate, and send a second transmission packet, including second data encoded with the first bitrate. The transmitter may send a first retransmission packet that includes the first data encoded with a second bitrate and the second data encoded with the second bitrate, and the first bitrate may be higher than the second bitrate.

Abstract: System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperature-calibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperature-calibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device. The trigger condition can include first use or power-on, charging, presence in an outdoor environment, variation in operating temperature, pre-specified time, and/or user input pertaining to the mobile device.

Abstract: Systems and methods for reducing boot time in a computer system divide the boot instructions into a start-up boot instruction segment and a mission-mode boot instruction segment. The start-up boot instruction segment is downloaded from persistent memory of the computer system to a random access memory (RAM) of the computer system and executed prior to a radio frequency (RF) analog (RFA) module of the computer system perform an RF calibration process that calibrates the RFA module to perform a wireless communication protocol. During the RF calibration process, the mission-mode boot instruction segment is downloaded from persistent memory to RAM and executed. Downloading the mission-mode boot instruction segment during the RF calibration process greatly reduces the overall amount of time required to boot the computer system.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first peripheral device may establish, with a user equipment (UE), a first connected isochronous stream (CIS), a second CIS, and a control channel for the first CIS and the second CIS, where the first peripheral device is configured to output audio signals for the first CIS and handle feedback for the first CIS. The first peripheral device may transmit, to a second peripheral device paired with the first peripheral device, an indication that the second peripheral device is to output audio signals for the second CIS and handle feedback for the second CIS. The first peripheral device may receive the first CIS, while maintaining the control channel for the first CIS and the second CIS. Numerous other aspects are described.

Abstract: Systems and methods for network coordination are disclosed. A method comprises listening to a primary device during a receiving slot group of a primary/secondary (P/S) piconet shared between the primary device and the secondary device, determining based on the listening during the receiving slot group whether the primary device is attempting to communicate with the secondary device, listening to a host device on a host piconet during a transmitting slot group of the P/S piconet in response to a determination that the primary device is not attempting to communicate with the secondary device, and transmitting to the primary device over the P/S piconet during the transmitting slot group of the P/S piconet in response to a determination that the primary device is attempting to communicate with the secondary device.

Abstract: Systems and methods for Bluetooth voice link shadowing are disclosed. A primary device may receive an eSCO packet from host device over master slot(s) of an enhanced synchronization connection oriented (eSCO) window within an interval of a host piconet shared between the host and primary devices. A secondary device may sniff for the eSCO packet also over master slot(s) of the eSCO window. When the primary device successfully receives the eSCO packet from the host, it may unconditionally relay the packet to the secondary device. Alternatively, it may conditionally relay the packet when the secondary device does not successfully sniff the packet. When the secondary device successfully sniffs the eSCO packet from the host, it may unconditionally relay the packet to the primary device. Alternatively, it may conditionally relay the packet when the primary device does not successfully receive the packet.
