Abstract: In some implementations, a user equipment (UE) may perform a decoding of downlink control information (DCI) via a physical downlink control channel (PDCCH) based on: a detection, by the UE, of a UE-specific scrambling sequence and a radio network temporary identifier (RNTI) corresponding to the UE-specific scrambling sequence; and a skipping, by the UE, of a de-scrambling operation prior to the decoding of the DCI, wherein information regarding the UE-specific scrambling sequence and the RNTI is not previously stored by the UE. The UE may refrain from decoding a plurality of possible UE-specific scrambling sequences based on the skipping of the de-scrambling operation prior to the decoding of the DCI.

Abstract: In some implementations, a receiver may obtain a digitized output of a radio frequency (RF) analog-to-digital-converter (ADC) of the receiver. The receiver may apply a spur cancellation to the digitized output of the RF ADC to attenuate one or more continuous wave spurs from the digitized output of the RF ADC, wherein the spur cancellation is based on a frequency planning with coherent averaging.

Abstract: A system includes a computing platform communicatively coupled to multiple network nodes, the computing platform having processing hardware and a memory storing a software code. The processing hardware is configured to execute the software code to detect multiple anomalous performance indicators originating from one or more of the network nodes, determine, using the anomalous performance indicators in an automated process, the occurrence of an incident, and determine the signature of the incident. The processing hardware is further configured to execute the software code to compare the signature to one or more entries in an incident signature database, perform, when the comparison determines that the signature corresponds to one or more of the entries, a root cause analysis of the incident using the corresponding one or more entries, and generate an incident alert including one or both of a result of the root cause analysis and a description of the incident.

Abstract: A device including an array of pixels and a filter wheel may capture a plurality of images by exposing the array of pixels. The device may spin, while capturing the plurality of images, the filter wheel, and the filter wheel may include filter segments. In some implementations, a portion of the filter wheel in front of the array of pixels includes two or more filter segments.

Abstract: According to examples, an optical fiber monitoring apparatus may include an optical time domain reflectometer (OTDR), and a 1×N optical splitter that is optically connected to the OTDR. For N being greater than one, the 1×N optical splitter may include N test port optical fiber outputs. Further, each test port optical fiber output may be optically connectable to an optical fiber to optically connect the optical fiber to the OTDR.

Abstract: In some examples, high speed bidirectional OTDR-based testing may include transmitting data from a first end of a device under test (DUT) towards an optical time-domain reflectometer (OTDR) that is operatively connected to a second opposite end of the DUT. Further data that is transmitted by the OTDR may be received from the second opposite end of the DUT towards the first end of the DUT. Based on an amplitude of the further data, a direction of receiving of the further data may be adjusted towards a first receiver or towards a second receiver.
