Abstract: A LoRa device for communicating sensor signals in a low power wide area network (LPWAN) includes a physical layer using Hamming encoding and Gray indexing with chirp spread signal (CSS) modulation to encode and modulate the sensor signals and a medium access layer (MAC) including a compressive sensing sub-layer which reduces encoded, modulated signals to sparse vectors. A transmission packet is formed by combining the sparse vectors with a selected set of sparse vectors representing past measurements and the incoming velocity of the sensor signals. A receiver decompresses the transmission packet by reconstructing, at a sparse recovery sub-layer of a receiver MAC layer, the encoded, modulated sensor signals. A decoder path removes the CSS modulation and Gray indexing, and Hamming decodes the sensors signals.

Abstract: A method for controlling packet routing in a network includes identifying segment identifications (IDs) for a number of switches and arranging a first number of the segment IDs into a multi-protocol label switching (MPLS) label field. The method further includes identifying an output port of a respective one of the number of switches located along a network path between source and destination nodes. The switches may route the packet based on corresponding ones of the segment IDs in the MPLS label field. In performing this routing operation, each switch may modify the MPLS label field with remaining ones of the segment IDs that have been shifted in position and padded with zeros, after the segment ID corresponding to the switch has been popped from the MPLS label field. The method therefore presents a technique for performing segment routing through network equipment designed to support MPLS routing.

In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information.
