Facilitating incremental downlink control information design to support downlink control information scheduling
First Claim
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.

Abstract
A system facilitating incremental downlink control information (DCI) design to support DCI scheduling in a wireless communication system is provided. In one embodiment, the an apparatus comprises: a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations comprise: 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, and wherein the second downlink control information comprises incremental downlink control information that is distinct from the first downlink control information.

6. A method, comprising:
-
determining, by a base station device comprising a processor, a first number of scheduling grants for uplink data transmission by a mobile device to the base station device; facilitating transmitting, by the base station device, first downlink control information associated with a first search space and comprising a first size, of a downlink control channel; and facilitating transmitting, by the base station device, second downlink control information associated with a second search space, comprising a second size, of the downlink control channel, wherein the second size is less than the first size, and wherein the second downlink control information comprises incremental downlink control information the size of which is dictated by the first downlink control information, wherein the incremental downlink control information comprises a first scheduling grant for a first user data packet to be transmitted, 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 and 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. - View Dependent Claims (7, 8, 9, 10, 11)

12. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
-
determining a first number of scheduling grants for uplink data transmission by a mobile device to a base station device; transmitting first downlink control information associated with a first search space of a downlink control channel, the first search space comprising a first size; and transmitting second downlink control information associated with a second search space of the downlink control channel, the second search space comprising a second size, wherein the second size is less than the first size, wherein the second downlink control information comprises incremental downlink control information that specifies user data information, and wherein the incremental downlink control information comprises a first scheduling grant for a first user data packet to be transmitted, 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 to dictate scheduling based on the baseline downlink control information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
