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: A device including a host logic and a wireless controller. The wireless controller includes a transceiver and a scheduler. The scheduler is configured to determine a first device and a second device to cluster together. Further, upon occurrence of a communication event, the scheduler is configured to wakeup the transceiver for a period of time for the transceiver to exchange packets with the first and second devices, exchange a packet with the first device, exchange a packet with the second device, and power down the transceiver.

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 method includes receiving, by a device, a portion of a data packet from a peer device during a reception time period, decoding a portion of a protocol data unit (PDU) of the data packet, decoding at least a portion of a header of the PDU, determining that the data packet is an empty packet according to the header, and aborting, by the device, reception of a remaining portion of the data packet to early terminate the reception time period.

Abstract: A method includes communicating with a remote device using a first access node of an access network; determining, by a centralized stack node of the access network, that a quality of a first wireless communication link between the remote device and the first access node is below a threshold; identifying a second access node in the access network for which a quality of a second wireless communication link between the remote device and the second access node is above the threshold; responsive to identifying the second access node, updating, by a centralized controller of the stack node, an access node identifier associated with a connection with the remote device to be an identifier for the second access node; and communicating with the remote device using the second access node.

Abstract: A first BLUETOOTH device includes a transceiver configured to receive a control procedure packet from a second BLUETOOTH device during a BLUETOOTH connection event of a BLUETOOTH connection between the first BLUETOOTH device and the second BLUETOOTH device. The first BLUETOOTH device also includes a controller coupled to the transceiver and configured to set a more data (MD) bit of a response packet to the control procedure packet to a first value independent of whether the first BLUETOOTH device has more data to send to the second BLUETOOTH device. The first value corresponds to maintaining the BLUETOOTH connection event open. The transceiver is further configured to send the response packet to the second BLUETOOTH device during the BLUETOOTH connection event.

Abstract: In an example, a method includes broadcasting advertising packets from a broadcaster BLUETOOTH device, where the advertising packets include one or more connection parameters for one or more links in a link cluster. The method also includes receiving, at the broadcaster BLUETOOTH device, a link cluster coordination request from a scanner BLUETOOTH device, where the link cluster coordination request includes one or more connection parameters for a link in the link cluster.

Abstract: A method includes receiving, by a peripheral device, a first connection request from a first central device; providing, by the peripheral device, a first indication of an anchor point time to the first central device before establishing a first wireless connection with the first central device; and responding, by the peripheral device, to the first connection request and establishing the first wireless connection using a first anchor point based on the first indication.
