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: Various aspects of the present disclosure generally relate to wireless communication and testing. In some aspects, a device may receive information identifying a mount orientation of a wireless communication device, wherein the mount orientation indicates an orientation of a coordinate system of the wireless communication device relative to a coordinate system of a positioner. The device may capture measurement information at each position of a set of positions of the wireless communication device, wherein the set of positions comprises positions of the wireless communication device as the wireless communication device is rotated around an axis by the positioner, and wherein the measurement information is captured based at least in part on the mount orientation. The device may provide information identifying the measurement information. Some techniques and apparatuses described herein may use the measurement information to generate a codebook for beam generation. Numerous other aspects are provided.
