  • Patent number: 11910360
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.

  • Patent number: 11871238
    Abstract: Described herein are systems and methods to improve multicast network performance by improving bootstrap message (BSM) in a bootstrap router (BSR). After BSR election, all candidate Rendezvous Points (C-RPs) send their group-to-RP mapping information to the elected BSR (E-BSR). The E-BSR collects the group-to-RP information from C-RPs and forms bootstrap message (BSM) comprising information of a RP set. A global flag and one or more group flags are incorporated into the BSM to indicate whether the BSM has changed since last transmission and which part of the BSM has changed. The length of the BSM to be transmitted may be dynamically determined. Upon receiving the BSM, each multicast router may operate according to the flags embedded in the BSM. Therefore, the processing process for the BSM at multicast router side may be simplified.

  • Patent number: 11757761
    Abstract: A dataflow hierarchy protocol is implemented by one or more devices to optimize how the one or more devices process datagrams for network communications. The dataflow hierarchy considers various available network pathways for dataflow. A device implementing the dataflow hierarchy selects one or more of the available network pathways to provide low latency in data communication with other devices. The device may sample various available network pathways to determine pathway metrics (e.g., latency) and select one or more network pathways based on the metrics. The available network pathways can include pathways through one or more intermediary nodes, such as pathways through a game server, pathways through a cell tower, and pathways through a network.
