  • Patent number: 9775005
    Abstract: Data transmission in a multicast fashion in which retransmissions are requested by recipients sending feedback to the one sender. Receiving stations are informed about the feedback of another receiving station. This is done by mirroring the feedback of receiving stations to other receiving stations. Due to this, in case, for example, one of the mirrored feedbacks is a negative acknowledgement message, the other receiving stations are informed that it is no longer necessary to provide their feedback, since a retransmission will be initiated anyway. Advantageously, this may allow reduced interference in the direction of the feedback.

  • Patent number: 9723547
    Abstract: Embodiments describe methods, apparatuses and logic for a user equipment (UE) to connect to an access point (AP) in a wireless local area network (WLAN) based on credentials from a UE's home third generation partnership project (3GPP) network. In some embodiments, the UE may receive selection policy parameters from the WLAN including a network access identifier (NAI) realm. The UE may also receive selection policy parameters from the 3GPP network. The UE may compare the selection policy parameters of the WLAN with the selection policy parameters of the 3GPP network and discover roaming relationships between service providers and the relative priorities of different networks, and create a network list based on the comparison. The UE may then associate with an AP of the WLAN based on the prioritized network list.

  • Patent number: 9716659
    Abstract: Systems and methods are provided for quality of service over broadband networks. A network device performs a probe transaction over a tunnel of a broadband network. Based on the probe transaction, parameters are determined reflecting tunnel performance, and, based on the parameters, target transmit and receive rates are determined for data communications over the tunnel. Based on the target transmit and receive rates, data communications to and from a first node of the network are regulated. When the tunnel comprises a peered tunnel, the regulation of received data communications comprises performing a set rate transaction with a peer second node of the network (the set rate transaction establishes a rate for data transmitted over the tunnel by the peer second node to the first node). When the tunnel comprises a peerless tunnel, the regulation of received data communications comprises shaping data traffic received by the first node over the tunnel.
