Abstract:
1. A method comprising: receiving, at a first cellular base station of a cell, uplink signals from multiple respective mobile devices managed by the first cellular base station; determining signal-to-noise ratios for the uplink signals received from the multiple mobile devices; and in response to the signal-to-noise ratios being less than an interference threshold for at least a particular amount of time, the particular amount of time being dependent on a number of the multiple mobile devices having signals with signal to-noise ratio measurements that are less than the interference threshold, determining, based on a direction from the first cellular base station to the multiple mobile devices and a cell topology of a cellular communications system that includes the first cellular base station, a neighboring cell generating interference for the multiple mobile devices, and communicating, from the first cellular base station to a second cellular base station managing the neighboring cell, a request effective to cause the second cellular base station to reduce the interference for the multiple mobile devices.
