Abstract: It is described a method for managing a radio transmission between a base station and a user equipment, wherein a communication channel is used for the radio transmission, wherein the communication channel includes a plurality of channel resources and is based on a MIMO transmission scheme. The method includes dividing the plurality of channel resources into a set of channel resource regions, assigning a MIMO rank to each channel resource region, wherein the MIMO rank is indicative for a number of channel resources to be used for a radio transmission within a corresponding channel resource region, selecting a channel resource region for the radio transmission between the base station and the user equipment, and managing the radio transmission between the base station and the user equipment based on the selected channel resource region and the corresponding assigned MIMO rank.
