1. An apparatus for use with a control element or function, the apparatus comprisingat least one processing circuitry, and
at least one non-transitory memory for storing instructions to be executed with the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least:to receive assistance information indicating communication conditions of at least one communication link of an established multi-connectivity communication between a communication element and at least two communication network access points, wherein the assistance information comprises at least an indication of a cost corresponding to an estimated probability of a successful transmission of a given data amount via the at least one communication link of the established multi-connectivity communication, comprising at least one of:a portion of overall communication channel capacity, or
a portion of currently unused communication channel capacity,
to process the assistance information for preparing a packet duplication control wherein, in the packet duplication control, data to be communicated via the at least one communication link of the established multi-connectivity communication are duplicated for being transmittable via another communication link of the established multi-connectivity communication,
to generate transmission control information on the basis of a result of the processing of the assistance information, the transmission control information indicating settings for a packet duplication process in the established multi-connectivity communication, and
to send the transmission control information to at least one transmission control element or function being involved in the packet duplication process in the established multi-connectivity communication.
