Abstract

A method for operating a distributed base station includes performing Hybrid Automatic Repeat Request (HARQ) processing. The distributed base station comprises a centralized processing entity and distributed remote radio access points, which are coupled to the centralized processing entity via a backhaul connection. The HARQ processing is performed locally by the remote radio access points, by performing an assessment a quality of received data and/or current radio conditions. Based on the assessment, it is decided locally on a necessity of re-transmissions without decoding the received data at the remote radio access points.
