Abstract: Certain aspects of the present disclosure generally relate to jamming detection for radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first counter configured to count a number of times that a power of a reception signal exceeds a first threshold. The apparatus also includes a second counter configured to count a number of measurements of the power of the reception signal. The apparatus further includes control logic having a first input coupled to an output of the first counter and having a second input coupled to an output of the second counter. The control logic is configured to determine an amount of jamming over a measurement window based on the number of times that the power of the reception signal exceeds the first threshold and on the number of measurements.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a first message indicating a capability to linearize a digital signal outputted by an analog front end of the UE, the digital signal being associated with a first transmission. The UE may receive the first transmission, the first transmission being associated with a gain state comprising a set of configurations associated with a plurality of amplifiers at the UE, and the UE may linearize the digital signal associated with the first transmission based at least in part on the gain state, where linearizing the digital signal comprises obtaining an output voltage value corresponding to an input voltage value associated with the analog front end. In some examples, the UE may obtain an output voltage value from a lookup table (LUT) of a set of LUTs configured to the UE or generated by the UE.

Abstract: An apparatus is disclosed for jammer detection. In example aspects, the apparatus includes a wireless transceiver configured to be connected to one or more antennas. The wireless transceiver is configured to translate a received signal from a first frequency to a second frequency using a reference signal to produce a translated received signal, with the reference signal including at least one frequency having an association with one or more targeted frequencies of a potential jamming signal. The wireless transceiver is also configured to convert at least a version of the translated received signal in the analog domain into a converted received signal in the digital domain. The wireless transceiver is further configured to detect that the converted received signal comprises a jamming signal based on the association and using at least one threshold and determine a jamming frequency of the jamming signal based on the frequency of the reference signal.
