Enhanced physical downlink control channel are multiplexed with physical downlink data channel in frequency division multiplexing (FDM), or in frequency division multiplexing (FDM)+time division multiplexing (TDM). FDM mode applies to users that have only UL grants in that subframe. UL grants of different users are cross-interleaved and transmitted over the entire physical resource blocks (both slots) in FDM. Frequency resources for cross-interleaved UL grants are distributed. TDM+FDM applies to users that have both DL and UL grants, or have only DL grant in that subframe. DL/UL grant (maybe mixed) is transmitted only in the first slot of physical resource blocks in TDM+FDM, where the second slots in those resource blocks can be used for those users' downlink data transmission. |
