Systems and methods for automatically analyzing spectral power measurements to identify abnormalities. The systems and methods may receive measurements comprising RF power measured over a contiguous range of frequencies, where at least a first portion of the contiguous range is used to transmit signals and at least a second portion of the contiguous range is unused. Respective boundaries of the unused portions may be identified and infilled to provide modified measurements. The modified measurements may be automatically analyzed to identify the abnormalities.

A base station (UE) is configured to perform a computer-implemented method for antenna fault detection and correction. The computer-implemented method includes acquiring one or more sounding reference signals (SRSs) received from at least one gNB antenna; detecting an antenna failure based on the one or more SRSs; estimating a noise power based on the antenna failure and a history of received SRSs; detecting a missing SRS based on the noise power and the history of received SRSs; and handling the missing SRS. Handling the missing SRS is based on performing at least one of: replacing an SRS measurement with a predicted SRS value for the missing SRS when the predicted SRS is available; or avoiding use of the missing SRS in a sequential SRS prediction when the predicted SRS is unavailable.

Systems and methods for identifying Passive Intermodulation (PIM) products are disclosed. Some embodiments use RAN Performance Measurement (PM) counters, of actual DL Traffic Load to correlate with UL noise and interference counters. By using counters, the DL traffic is correlated to the increase in noise and interference in order to determine which DL carrier combinations are causing degradation to which UL carriers. In this way, aggressor-victim grouping can be identified through normal downlink traffic load with uplink interference to identify passive intermodulation products. This can be done for all aggressor-victim groups within a radio base station site or cluster of sites. Also, some embodiments enable estimating the maximum PIM interference created by the aggressor carriers. This helps operators to quantify the impact of PIM and can enable them to take counter measures. These embodiments are Radio Access Technology (RAT) agnostic and operator agnostic for the aggressors within a site.

Methods, systems, and devices for wireless communications are described for autonomous block error rate (BLER) threshold determination fur use in beam failure indication (BFI) procedures. A user equipment (UE) that is capable of autonomously determining a BLER threshold value may provide an indication of the capability to a base station. The base station may provide configuration information that enables the UE to perform autonomous BLER threshold determination, and the UE may determine the BLER threshold value based on the configuration information. The UE may determine that a BFI has occurred based on the determined BLER threshold, and thereby enhance beam failure detection procedures to provide more efficient and reliable communications.
