Abstract
The present disclosure relates to a serving wireless communication node adapted to predict data files (A, B, C) to be requested by at least two served user terminals () and to form predicted sub-data files (A, A; B, B; C, C). In a placement phase, the serving node is adapted to transmit predicted sub-data files (A, B; A, B) to cache nodes (AP, AP), each cache node (AP, AP) having a unique set of predicted different sub-data files of different predicted data files, and to receive requests (RA, RB) for data files from the served user terminals (). In a delivery phase, the serving node is adapted to transmit an initial complementary predicted sub-data file (Formula I) to the cache nodes (AP, AP), comprising a reversible combination of the remaining predicted sub-data files (A, B) for the files requested. If a cache node (AP, AP) requests re-transmission (RA; RB) of a predicted sub-data file (A, B), the serving node (AP) is adapted to transmit a further complementary predicted sub-datafile (Formula II) to the cache nodes (AP, AP), the file comprising a reversible combination of at least one re-transmitted predicted sub-data file (A, B) and at least one new predicted sub-data file (C).
