Abstract: The invention relates to a method for using a user equipment with a radio access network of or associated or assigned to a mobile communication network, wherein the radio access network comprises at least one base station entity, wherein the base station entity serves the user equipment using multi-user multiple input multiple output, MU-MIMO, technology, in a manner such that, at least regarding specific time-frequency resources of the air interface of the base station entity, both the user equipment and a further user equipment are simultaneously served by the base station entity or provided with transmission resources, wherein, in order to use both the user equipment and the further user equipment with the radio access network using multi-user multiple input multiple output, MU-MIMO, technology, the method comprises the step of—the user equipment receiving first transmission configuration information in view of applying multi-user multiple input multiple output, MU-MIMO, technology,—the further user equipm

Abstract: A method for enabling communication between a user equipment and a mobile communication network includes: operating an antenna entity or functionality or configuring the antenna entity or functionality such that the shape of a coverage area of a radio cell is configured or configurable in a predefined manner other than circular or elliptical. The mobile communication network is or at least comprises a part corresponding to or being a non-terrestrial network. The user equipment is served by a base station entity which is part of that non-terrestrial network or that non-terrestrial network part. The base station entity has or is provided with—in view of serving or providing radio coverage to the user equipment—at least the antenna entity or functionality.

Abstract: A method for transmitting a service time interval or service time information to a user equipment in a mobile communication network includes: transmitting, by a base station entity, reference location information and the service time information to the user equipment, wherein the reference location information relates to the currently covered area or a part thereof, and the service time information relates to a time at which the base station entity is likely to stop serving the currently covered area. The mobile communication network is or at least comprises a part corresponding to or being a non-terrestrial network. The user equipment is served by a base station entity being part of that non-terrestrial network or that non-terrestrial network part. The base station entity has or is provided with—in view of serving or providing radio coverage to the user equipment—at least an antenna entity or functionality.
