Abstract: Methods and devices for synchronizing a device clock in a wireless network (e.g. a LPWAN) are disclosed. Example methods comprise identifying a device temperature, identifying a clock drift associated with the identified device temperature and applying a correction to the device clock based on the identified drift. For the identified device temperature, the drift is identified by comparing the confidence of the drift value in a pre-calibration curve generated from fixed drift values in a pre-calibration table with the confidence of the drift value in a learning curve generated from variable drift values in a learning table and selecting the drift value from the curve having the higher drift confidence.

Abstract: Network access node virtual fabrics configured dynamically over an underlay network are described. A centralized controller, such as a software-defined networking (SDN) controller, of a packet switched network is configured to establish one or more virtual fabrics as overlay networks on top of the physical underlay network of the packet switched network. For example, the SDN controller may define multiple sets of two of more access nodes connected to the packet switched network, and the access nodes of a given one of the sets may use a new data transmission protocol, referred to generally herein as a fabric control protocol (FCP), to dynamically setup tunnels as a virtual fabric over the packet switched network. The FCP tunnels may include all or a subset of the parallel data paths through the packet switched network between the access nodes for a given virtual fabric.

Abstract: Systems and methods for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions are presented. In one exemplary embodiment, a method includes receiving a signal that includes B bits for identifying a reference signal. Each of several available reference signals are defined by a cyclic shift and an orthogonal cover code. Further, the method includes using the B bits to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

A control information reception method of a terminal includes receiving control information from a base station using a first module, determining a channel occupancy time based on the control information using a licensed assisted access (LAA) radio identifier, and transferring the channel occupancy time to a second module that is operating in a same frequency band as the first module.

Abstract: Systems and processes for operating an intelligent automated assistant are provided. In one example process, an event associated with an audio input is detected with a first process. In accordance with a detection of the event, a delay value associated with an electronic device is determined. The delay value corresponds to a time required to determine, with a second process, whether the audio input includes a spoken trigger. In accordance with a determination that the delay value exceeds a threshold, the delay value is broadcast during a first advertising session, and determination is made, during a second advertising session, whether the electronic device is to respond to the audio input. In accordance with a determination that the threshold is not exceeded, a determination is made, during the first advertising session, whether the electronic device is to respond to the audio input or wait for the second advertising session.

Abstract: Techniques are disclosed for aggregating bandwidth from multiple sources. In embodiments, a user device, such as a cellular telephone, may have a communications channel established with both a cellular tower and a wireless access point (WAP). When the user device transmits data, this data transmission may be divided between the multiple communications channels concurrently, so as to utilize the combined bandwidth of the multiple channels. Each communication channel may be prioritized, such as by prioritizing using the cellular channel until it is at capacity, and then using the WAP channel.

Abstract: Examples disclosed herein relate to path-synchronous performance monitoring of an interconnection network based on source code attribution. A processing node in the interconnection network has a profiler module to select a network transaction to be monitored, determine a source code attribution associated with the network transaction to be monitored, and issue a network command to execute the network transaction to be monitored. A logger module creates, in a buffer, a node temporal log associated with the network transaction and the network command. A drainer module periodically captures the node temporal log. The processing node has a network interface controller to receive the network command and mark a packet generated for the network command to be temporally tracked and attributed back to the source code attribution at each hop of the interconnection network traversed by the marked packet.

Abstract: Techniques are provided for generating data on the optimum number of storage-hops, the location of the storage-hops, and the bandwidth distributions of the storage-hops to construct a complete flow network for transmitting data from a sender to a receiver via a communication network. The flow network can potentially include hundreds of storage-hops, depending on the time and duration of the data flow. An algorithm is further provided for constructing an unbounded flow network from a bounded set of input parameters. Moreover, the complexity of the algorithm does not depend on the number of storage-hops, so the model is suitable for both crowd supported and data center supported transfers.
