1. An apparatus, comprising:

  • a processor; and

    a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

    receiving first downlink control information associated with a first search space of a downlink control channel, wherein the first search space is of a first size; and

    receiving second downlink control information associated with a second search space of the downlink control channel, wherein the second search space is of a second size that is less than the first size, wherein the second downlink control information comprises incremental downlink control information that is distinct from the first downlink control information and specifies user data information, wherein the incremental downlink control information comprises a first scheduling grant for a first user data packet to be transmitted from a wireless device to the apparatus, wherein the incremental downlink control information specifies the first user data packet on a first downlink traffic channel, and wherein a baseline downlink control information schedules a rank 1 physical downlink shared channel while the incremental downlink control information schedules a subband high rank physical downlink shared channel with a second rank higher than rank 1 and configured to overwrite scheduling based on the baseline downlink control information.
