Improved physical downlink control channel (ePDCCH) with pooling of physical resource blocks (PRB)

摘要

A method for grouping physical resource blocks of an enhanced downlink control physical channel, ePDCCH, with a downlink shared physical channel, PDSCH, into a wireless device (720), the method comprising the steps of: receiving (620) of a node in the wireless device (720) the ePDCCH in a block of physical resources ePDCCH (230a, 230b, 230c) contiguous in frequency with at least one block of PDSCH physical resources (232a, 232b) carried by the PDSCH ; receiving (610) an indication from a node (710) that the ePDCCH physical resource block (230a, 230b, 230c) carried by the ePDCCH is excluded from the physical resource block grouping when the PDSCH is transmitted with a larger category that 4 and / or when multiple multiple input multiple user output is applied; and in response to the indication, group (630) the at least one physical resource block (232a, 232b) carried by the PDSCH without the ePDCCH physical resource block for channel estimation and / or demodulation.
