MANAGING A MASSIVE MULTIPLE INPUT MULTIPLE OUTPUT BASE STATION

Abstract:

A method for managing a Massive Multiple Input Multiple Output (M-MIMO) base station is disclosed. The method comprises receiving from a neighbour base station a notification of load conditions at the neighbour base station (110) and obtaining measurements on communication resources associated with the neighbour base station (120). The method further comprises determining whether there exists within a spatial distribution of traffic served by the neighbour base station a region having a concentration of traffic which is above a threshold level (130), and, if such a region exists, and if a condition for load transfer from the neighbour base station is fulfilled, causing at least one reference signal transmitted by the M-MIMO base station to be transmitted towards the determined region with a signal strength sufficient to trigger handover of a device in the determined region to the M-MIMO base station (160).
