Managing a Radio Transmission Between a Base Station and a User Equipment

The method as set forth in claim 2, wherein, within a channel resource region, a multiple input multiple output rank is used for a radio transmission being equal to or being lower than the multiple input multiple output rank being assigned to the channel resource region.

A base station for managing a radio transmission between the base station and a user equipment, wherein a communication channel is used for the radio transmission, wherein the communication channel comprises a plurality of channel resources and is based on a multiple input multiple output transmission scheme, the base station comprising

• a control unit being adapted to divide the plurality of channel resources into a set of channel resource regions, being adapted to assign a multiple input multiple output rank to each channel resource region, wherein the multiple input multiple output rank is indicative for a number of channel resources to be used for a radio transmission within a corresponding channel resource region, and being adapted to select a channel resource region for the radio transmission between the base station and the user equipment, and
• a managing unit being adapted to manage the radio transmission between the base station and the user equipment based on the selected channel resource region and the corresponding assigned multiple input multiple output rank.
