A method performed by a network configuration manager to configure at least one of a plurality of network entities (AP1, UE1) of a radio communications network, wherein the method comprises: receiving radio-domain operating characteristics (r(n)) via a southbound interface (SBi), wherein the received radio-domain operating characteristics (r(n)) represents at least partly a present state of the radio communications network, wherein the radio-domain characteristics (r(n)) comprises at least one of the following: an active QoS parameter, an active traffic class, a number of available radio resources, a number of occupied radio resources, and a spatial position of the at least one network entity; receiving environment information (e(n)) via an environment interface (ENi), wherein the environment information (e(n)) represents at least partly a present state of an environment in which the plurality of network entities (AP1, UE1) are operating, wherein the environment information (e(n)) comprises at least one of the following: a spatial position of at least one of a plurality of objects not participating in the radio communications network, in particular of objects not necessarily participating in the radio communications network, a spatial dimension of the at least one of a plurality of objects not participating in the radio communications network, in particular of objects not necessarily participating in the radio communications network, a spatial position and size of an opening in a room or building, an operating state of an actuator for opening or closing an opening in the room or building; determining a configuration (c(n+1)) for the at least one of the plurality of network entities (AP1, UE1) via a configuration determination unit in dependence on the received radio-domain operating characteristics (r(n)) and in dependence on the received environment information (e(n)); and transmitting the determined configuration (c(n+1)) towards the at least one of the plurality of network entities (AP1, UE1) via a northbound interface (NBi) and/or the southbound interface (SBi) in order to reconfigure the at least one of the plurality of network entities (AP1, UE1). receiving radio-domain operating characteristics (r(n)) via a southbound interface (SBi), wherein the received radio-domain operating characteristics (r(n)) represents at least partly a present state of the radio communications network, wherein the radio-domain characteristics (r(n)) comprises at least one of the following: an active QoS parameter, an active traffic class, a number of available radio resources, a number of occupied radio resources, and a spatial position of the at least one network entity; receiving environment information (e(n)) via an environment interface (ENi), wherein the environment information (e(n)) represents at least partly a present state of an environment in which the plurality of network entities (AP1, UE1) are operating, wherein the environment information (e(n)) comprises at least one of the following: a spatial position of at least one of a plurality of objects not participating in the radio communications network, in particular of objects not necessarily participating in the radio communications network, a spatial dimension of the at least one of a plurality of objects not participating in the radio communications network, in particular of objects not necessarily participating in the radio communications network, a spatial position and size of an opening in a room or building, an operating state of an actuator for opening or closing an opening in the room or building; determining a configuration (c(n+1)) for the at least one of the plurality of network entities (AP1, UE1) via a configuration determination unit in dependence on the received radio-domain operating characteristics (r(n)) and in dependence on the received environment information (e(n)); and transmitting the determined configuration (c(n+1)) towards the at least one of the plurality of network entities (AP1, UE1) via a northbound interface (NBi) and/or the southbound interface (SBi) in order to reconfigure the at least one of the plurality of network entities (AP1, UE1).
