A micro base station comprising a cache-memory to provide files to a user-equipment

The invention relates to a micro base station (100a-d) configured to provide a file of a plurality of files to an user equipment (101a-c) within the service area (103a) of a macro base station (103), wherein each file of the plurality of files can be decomposed into a plurality of file fragments. The micro base station (100a-d) comprises a cache memory (105a) configured to store a subset of the plurality of file fragments of the plurality of files, a communication interface (107a) configured to receive a request by the user equipment (101a-c) for a file of the plurality of files and a processor (109a) configured to provide any file fragments of the file requested by the user equipment (101a-c), which are part of the subset of the plurality of file fragments available in the cache memory (105a), to the communication interface (107a) for sending the file fragments to the user equipment (101a-c), wherein the processor (109a) is further configured to update the cache memory (105a) by replacing at least one of the file fragments of another file in the cache memory (105a) with at least one file fragment of the file requested by the user equipment (101a-c), which is not part of the subset of the plurality of file fragments available in the cache memory (105a).
