Certain aspects provide a method of wireless communications by a user equipment, such as a low-power user equipment. The method includes receiving, from one grouped user equipment of a first group of user equipments, an indication that the user equipment is a current group leader of the first group of user equipments; receiving, from one or more grouped user equipments of the first group of user equipments via a first wireless transceiver system, one or more data requests; and sending, to a network entity via a second wireless transceiver system, one or more data payloads associated with the one or more data requests.

The disclosed embodiments provide a distributed transaction system including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes configured to receive and process transaction requests, for example, to add new blocks to one or more blockchains. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The disclosed embodiments reduce the distributed system's reliance on the stability of any particular node(s) in the network, as the validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes. Further, the disclosed embodiments provide a scheme that helps ensure the Leader node, as well as the other Committee members, functions properly.

A communication system for point to multipoint communications by grouping client devices based on associated modes is provided. In one example implementation, point to multipoint communication improvements are achieved by grouping a plurality of client devices by their optimal modes for communication. For example, the communication system can determine, based on channel quality indicators (CQIs) that two client devices of a plurality of client devices are associated with an optimal first mode of a modal antenna. The system can group the two client devices into a first group, the first group associated with communication using the first mode of the modal antenna. The modal antenna can communicate with the first group using the first mode of a modal antenna during a single frame of communication.

Various systems and methods may be used to implement a software defined industrial system. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. The orchestrated system may include an orchestration server, a first node executing a first module, and a second node executing a second module. In response to the second node failing, the second module may be redeployed to a replacement node (e.g., the first node or a different node). The replacement mode may be determined by the first node or another node, for example based on connections to or from the second node.

A field data transmission method comprises: a cloud platform determining at least one first device operation index be obtained via data analysis. For each first device operation index, the cloud platform generates control information for the first device operation index. The control information is used to determine a primary edge controller from among at least one edge controller, wherein the primary edge controller is used to send first field data to the cloud platform, the first field data is used for data analysis by the cloud platform to obtain the first device operation index, and the first field data is obtained by the primary edge controller preprocessing second field data. The cloud platform sends each piece of control information to each edge controller, respectively. The cloud platform receives first field data from each primary edge controller, respectively.

Systems, methods, and other embodiments associated with distributed primary identifier management in a multi-master database system are described. One embodiment includes adding a new master node to a system with a plurality of master nodes. Assigning a master node number to the new master node in relation to the plurality of master nodes. The master node number is converted into a binary value and a reverse bit order of the master node number is generated. The new master node is configured to assign primary identifiers within an address space to data objects, wherein the primary identifiers include the reverse bit order of the master node number to reduce collisions between the data objects.

A method for operating a hearing device is specified. The hearing device is assigned to a user and connected to other hearing devices, which are each assigned to another user, for data exchange in a common network. The hearing device or one of the other hearing devices controls the data exchange by subscribing to the network as a master, and wherein all other hearing devices subscribe to the network as a slave. It is decided whether the hearing device subscribes to the network as a master or as a slave by determining the operational capability of the hearing device and comparing it with the operational capability of the other hearing devices and by the hearing device acting as a master if the hearing device has the highest operational capability, and otherwise as a slave.

A computer network device (such as a switch or a router) that implement host tracking is described. During operation, the computer network device may receive a report message that is associated with a host, which indicates that the host wants to join a group in a network that receives an audio-video channel from a source. In response, the computer network device may add information associated with the host to a group data structure associated with one or more hosts in the group. Then, when the computer network device receives a leave message that is associated with the host, the computer network device may remove or deactivates the host from the group data structure. Moreover, when the group data structure is empty or has no active hosts, the computer network device may stop forwarding the audio-video channel from the source to the group without further delay.

In some implementations, a system can be configured to allow remote control devices to quietly obtain status information related to various audio/video playback devices. For example, a streaming device (e.g., a user device, phone, etc.) can establish a streaming connection to a playback device. The playback device can be configured to only accept a single streaming connection (i.e., master connection). A remote control device (e.g., a user device, phone, etc.) can quietly connect (i.e., control connection) to the playback device without interrupting the master connection to obtain status information related to the playback device and or the media being streamed to the playback device. The remote control device can provide commands through the control connection to adjust the playback of the streamed media at the playback device.

Various embodiments relate to a wired local area network (WLAN) including a shared transmission medium (e.g., a 10SPE network). A method may include detecting an event in a WLAN including physical level collision avoidance (PLCA). The method may also include disabling a beacon of a first node operating as a master of the WLAN in response to the event. Further, the method may include enabling a second node to operate as the master of the WLAN.
