Abstract: A method for discovering and diagnosing network anomalies. The method includes receiving key performance indicator (KPI) data and alarm data. The method includes extracting features based on samples obtained by discretizing the KPI data and the alarm data. The method includes generating a set of rules based on the features. The method includes identifying a sample as a normal sample or an anomaly sample. In response to identifying the sample as the anomaly sample, the method includes identifying a first rule that corresponds to the sample, wherein the first rule indicates symptoms and root causes of an anomaly included in the sample. The method further includes applying the root causes to derive a root cause explanation of the anomaly and performing a corrective action to resolve the anomaly based on the first rule.

Abstract: An apparatus for performing a wireless communication includes a communication interface configured to measure uplink (UL) Sounding Reference Signals (SRSs) transmitted from a mobile client device, and at least one processor configured to buffer a number of uplink (UL) SRS measurements derived from UL SRS transmissions of the mobile client device, the number of UL SRS measurements exceeding a threshold, extract features from UL SRS measurements, obtain a machine learning (ML) classifier for determining a category to be used for estimating mobility associated with the mobile client device, and determine the category of the mobile client device by applying the extracted features to the ML classifier. Methods and apparatus extract the features of either a set of power spectrum density measurements or a set of pre-processed frequency domain real and imaginary portions of UL SRS measurements and feed the features to an AI classifier for UE speed estimation.

Abstract: A method of operating a base station (BS) for a coexistence operation in a wireless communication system is provided. The method comprises performing a first measurement of first signals received from neighbor BSs over channels that are shared with the neighbor BSs before receipt of a spectrum access grant from a network entity; generating a registration request comprising a first measurement report based on the first measurement of the first signals; transmitting, to the network entity, the registration request comprising the first measurement report of the first signals; receiving the spectrum access grant from the network entity; and performing a second measurement of second signals received from the neighbor BSs over the channels that are shared with the neighbor BSs after receiving the spectrum access grant from the network entity.

Abstract: A UE includes a transceiver configured to receive, from a base station, a higher layer parameter that is set as enabled or disabled. The higher layer parameter is explicitly or implicitly determined to be disabled by Boolean parameters or DL DCI format types. The UE also includes a controller configured to, based on identifying that the higher layer parameter is set as enabled either on per CORESET basis or on per DCI format basis, assume that, for receiving a PDSCH, an indication state is present in a DL DCI transmitted by a PDCCH on a CORESET, wherein the indication state indicates an associated PDSCH QCL parameter. A transceiver receives the associated PDSCH using the QCL parameter from the base station.
