Abstract (en)

[origin: WO2021033009A1] Systems and methods are disclosed herein for random access interference detection and mitigation. Embodiments of a method performed by a base station and corresponding embodiments of a base station are disclosed. In some embodiments, a method performed by a base station in a cellular communications system comprises detecting interference on at least a portion of a random access resource for a respective cell based on either or both of: (a) one or more expected signal characteristics of a single-tone frequency hopping random access preamble received in at least a portion of the random access resource and (b) frequency hopping patterns used by one or more other cells for single-tone frequency hopping random access preambles. The method further comprises performing one or more actions to mitigate the detected interference. In this manner, false alarm reduction can be reduced.
