MULTI-CHANNEL STATE INFORMATION FEEDBACK WITH CELL-SPECIFIC ADAPTIVE GRANULARITY

摘要

It is described a user equipment (104) for a cellular communication network (100) providing a plurality of cells (103a, 103b, 103c), the user equipment (104) comprising: a receiver unit (110) for receiving a first and second transmissions (106a, 106b, 106c) via a first and a second communication channel. The first communication channel uses a first cell (103a) and the second communication channel uses a different, second cell (103b, 103c) of said plurality of cells. A feedback unit (112) is configured for providing a first and second channel state information feedback components (108b, 108c) for the respective communication channels with a separate, cell specific granularity. Further described is a base station (102a, 102b, 102c) of the cellular communication network.
