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.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a smart friend request message to a set of nodes in the wireless mesh network. The set of nodes may be associated with a friend feature that may include maintaining one or more element messages intended for the first node when the first node is in a low power state. Each of the one or more element messages intended for the first node may include an element address corresponding to an element at the first node. The smart friend request message may indicate a hierarchy of element addresses to maintain at the second node. The apparatus may operate in the low power state during which the second node maintains the one or more element messages for the first node based at least in part on the hierarchy of element addresses.

Abstract: The disclosure relates to performing a reliable broadcast from a source device to a plurality of nodes. In an aspect, a representative node establishes a first wireless communication link with each of one or more non-representative nodes, receives, from each of the one or more non-representative nodes, information indicating an ability of the one or more non-representative nodes to sniff wireless communications, establishes a second wireless communication link with the source device, configures the second wireless link based on the information received from the one or more non-representative nodes, sends control information for the second wireless communication link to each of the one or more non-representative nodes, and receives communications from the source device over the second wireless communication link, wherein the one or more non-representative nodes sniff the communications on the second wireless communication link based on the control information for that link.
