摘要： A method includes generating multiple embedded features representing operational data of network elements in a wireless communication network. The method also includes generating a relationship graph based on the embedded features, the relationship graph representing behavior of the network elements in the wireless communication network. The method also includes detecting one or more anomalies in the wireless communication network using the relationship graph, the one or more anomalies identifying one or more deviations of one or more of the network elements from an expected behavior of the one or more network elements. The method also includes generating network analytics based on the one or more detected anomalies.

摘要： A method includes partitioning a set of configuration management (CM) data for one or more cellular network devices into multiple distinct time intervals. The method also includes determining one or more temporal points of interest in each time interval based on whether CM changes exist during that time interval. The method also includes, for each temporal point of interest in each time interval, identifying a first set of data samples before that temporal point of interest and a second set of data samples after that temporal point of interest, and averaging features and a target key performance indicator (KPI) in the first set of data samples and in the second set of data samples. The method also includes performing regression analysis to determine an impact of the features on the target KPI.

摘要： A hybrid MIMO system comprises N digital transceiver chains and N analog beamformers, each coupled to one of the digital transceiver chains and comprising M analog transmitter (TX) chains and M analog receiver (RX) chains. One of the analog RX chains is an RX reference node and one of the analog TX chains is a TX reference node. A processor is coupled to a calibration transceiver, the transceiver chains, and the beamformers. For each beamformer the processor measures, using the corresponding transceiver chain and the calibration transceiver, TX and RX phase responses and TX and RX magnitude responses of the TX and RX reference nodes, respectively, determines a reciprocity calibration based on a phase difference between the TX and RX phase responses and a magnitude difference between the TX and RX magnitude responses, and applies the reciprocity calibration to stored beam definitions to correct for the phase and magnitude differences.

摘要： Scalable 2D joint phase-time arrays (JPTA) support multiple simultaneous RF beams without sacrificing array gain. A 2D JPTA comprises M antenna groups that each comprise N antennas, each coupled to one of N phase shifters. The array comprises M delay elements configured to: apply a time delay to a first signal to be transmitted by one of the antenna groups while each phase shifter in the group phase shifts the time-delayed first signal and feeds the phase-shifted-and-time-delayed first signal to the corresponding antenna, or apply the time delay to a second signal received from the group while each phase shifter phase shifts a third signal received from the antenna, the second signal being a combination of the phase-shifted third signals. The time delays produce a beam spread in a first dimension of the array such that multiple beams are formed in different directions.

摘要： A method includes receiving a pilot signal or a measurement report from a user equipment (UE) or a base station (BS). The method also includes updating a CSI buffer with channel state information (CSI) obtained from the pilot signal or the measurement report, the CSI buffer configured to store previous uplink or downlink channel estimates. The method also includes providing at least a portion of the CSI buffer to a CSI predictor comprising an artificial intelligence (AI) model that utilizes one or more weight sharing mechanisms, the AI model comprising a sequence of layers. The method also includes predicting temporal CSI using the CSI predictor. Depending on the configured output, the method can also include and/or be used for denoising and frequency extrapolation.

A method for identifying resource scheduling for a UE includes receiving downlink control information; identifying, from the downlink control information, one or more DM-RS ports assigned to the UE and a PDSCH EPRE to DM-RS EPRE ratio; and identifying data intended for the UE in a resource block in a downlink subframe using the one or more DM-RS ports and the PDSCH EPRE to DM-RS EPRE ratio. A method for scheduling resources includes identifying one or more DM-RS ports to assign to a UE and a PDSCH EPRE to DM-RS EPRE ratio for identifying data intended for the UE in a resource block in a downlink subframe; and including an indication of the one or more DM-RS ports and the PDSCH EPRE to DM-RS EPRE ratio in downlink control information.
