1. A method of multiplexing physical downlink control channel and physical downlink data channel in two cases comprising:

  • determining uplink (UL and downlink (DL) needs of a plurality of users and generating subframes based on the determined needs, including;

    1) cross-interleaving scheduling grants for uplink data transmissions (UL grants) of different users and mapping the cross-interleaved UL grants to entire physical resource blocks containing first and second slots in which no physical downlink data channel is allowed to be transmitted, and wherein downlink control channel and physical downlink data channel for another user are multiplexed using frequency division multiplexing (FDM);

    2) mixing scheduling grants for downlink data transmission (DL grant) and for uplink data transmission (UL grant, if it is present) of a single user, and mapping both the DL grant and the UL grant to a first slot of physical resource blocks in which the second slot is allowed to be used for the single user'"'"'s downlink data transmission, wherein downlink control channel and physical downlink data channel for another user are multiplexed using frequency division multiplexing (FDM)+time division multiplexing (TDM).
