Abstract: A device (e.g., an IoT device) includes a first radio, and a memory device accessible to the first radio. The memory device is configured to store a fingerprinting feature for a specific transmitter device. A second radio and a processor are also included. The process is coupled to the first and second radios. The first radio is configured to extract a fingerprinting feature of a first received wireless signal, determine that the extracted feature matches the fingerprinting feature stored in the storage device, and responsive to the determination that the extracted feature matches the feature stored in the storage device, cause the second radio to transition from a lower power state to a higher power state of operation and continue to receive the incoming signal.

Abstract: A method includes storing a reference fingerprint for a first device in a database; operating a second device in an identity authentication mode; receiving, by the second device while operating in the identity authentication mode, a signal transmission from an unknown device; determining, by the second device, a fingerprint for the unknown device based on the signal transmission; responsive to the fingerprint of the unknown device matching the reference fingerprint for the first device, processing a data packet associated with the signal transmission; and responsive to the fingerprint of the unknown device not matching the reference fingerprint for the first device, ignoring the data packet associated with the signal transmission.

Abstract: A device (e.g., a BLUETOOTH device) includes memory and one or more processors coupled to the memory. The one or more processors are configured to implement a BLUETOOTH host, a BLUETOOTH host-controller interface, and a BLUETOOTH controller. The one or more processors are further configured to cause the BLUETOOTH controller to receive, from the BLUETOOTH host via the BLUETOOTH host-controller interface, a message indicating first channel and timing information for sending data corresponding to a BLUETOOTH application. The one or more processors are further configured to cause the BLUETOOTH controller to initiate sending the data based on the first channel and timing information.

Abstract: A user client device with a single receive (RX) chain, a first antenna and a second antenna, and a processor that causes the user client device to couple the single RX chain to the first antenna to receive a first data packet on a first channel and determine a first channel state information (CSI) tile of the first channel based on one or more fields in the first data packet, decouple the first antenna from the single RX chain and couple the second antenna to the single RX chain to continue receiving the first data packet on a second channel, determine a second CSI tile of the second channel based on one or more of a portion of the first plurality of fields, aggregate the first CSI tile with the second CSI tile, and generate a CSI matrix based on aggregating the first CSI tile with the second CSI tile.

Abstract: In an example, a method includes communicating between a first BLUETOOTH device and a second BLUETOOTH device via a first channel within a channel set at a first connection event using first channel specific parameters. The method also includes determining, by the first BLUETOOTH device, one or more channel cluster operation parameters for a second channel within the channel set at a second connection event using second channel specific parameters. The method includes communicating over the second channel during the second connection event from the first BLUETOOTH device to the second BLUETOOTH device using renegotiated second channel specific parameters.

Abstract: In at least one example, a method includes transmitting, by a first device, probe packets to a second device on multiple links over N transmission opportunities (TXOPs) with synchronous probing transmissions on the multiple links during each TXOP. N is an integer value greater than 1. Each probe packet corresponds to a different set of transmission parameters. Each link is established between the first device and the second device over different channels of a wireless transmission medium. The method further includes receiving, by the first device responsive to transmitting the probe packets, feedback from the second device on the multiple links in tandem with the synchronous probing transmissions over the N TXOPs. The method further includes selecting, by the first device, a preferred link from among the multiple links based on the feedback.

Abstract: A method includes detecting, by a coexistence controller of a system on a chip (SoC), an occurrence of a coexistence event of an SoC component; providing, by the coexistence controller, an indication of the occurrence of the coexistence event to a coexistence coordinator; and changing, by the coexistence controller, an operating point of the SoC from a current operating point to a new operating point responsive to receiving an operating point change request from the coexistence coordinator.

Abstract: A Bluetooth (BT) or Bluetooth Low Energy (BLE) controller includes: a physical (PHY) layer; a baseband radio frequency (RF) layer; and a link layer (LL). The LL is configured to: obtain an incoming transmission awareness request regarding a later incoming transmission event; and perform incoming transmission operations to prepare for the later incoming transmission event responsive to the incoming transmission awareness request.

Abstract: A method includes broadcasting, by a multicast anchor, a first message that advertises a multicast service for a multicast group, and receiving, by the multicast anchor from a BLE device, a unicast message that indicates a request to join a BLE device to the multicast group. The method further includes joining, by the multicast anchor, the BLE device to the multicast group as a multicast client, and transmitting, by the multicast anchor to the BLE device, one or more multicast messages for the multicast group.
