Enhanced control channel for dl sub-band scheduling

A scheduling entity in wireless communication with a set of one or more scheduled entities within a wireless communication network, the scheduling entity comprising:

• a transceiver;
• a memory;
• and
• a processor communicatively coupled to the transceiver and the memory, the processor configured to:
• schedule a set of one or more first resource elements within a first sub-band of a slot to a scheduled entity of the set of one or more scheduled entities based on a first rank and a first set of data streams assigned to the scheduled entity;
• schedule a set of one or more second resource elements within a second sub-band of the slot to the scheduled entity based on a second rank and a second set of data streams assigned to the scheduled entity, wherein the first rank is different from the second rank and the first set of data streams is different than the second set of data streams;
• and
• transmit scheduling information indicating the set of one or more first resource elements and the set of one or more second resource elements to the scheduled entity, the scheduling information further comprising stream identification information for each sub-band assigned to the scheduled entity within the slot.

A scheduling entity apparatus in a wireless communication network, comprising:

• first means for scheduling a set of one or more first resource elements within a first sub-band if a slot to a scheduled entity of a set of one or more scheduled entities based on a first rank and a first set of data streams assigned to the scheduled entity;
• second means for scheduling a set of one or more second resource elements within a second sub-band of the slot to the scheduled entity based on a second rank and a second set of data streams assigned to the scheduled entity, wherein the first rank is different from the second rank and the first set of data streams is different than the second set of data streams;
• and
• means for transmitting scheduling information indicating the set of one or more first resource elements and the set of one or more second resource elements to the scheduled entity, the scheduling information further comprising stream identification information for each sub-band assigned to the scheduled entity within the slot.

A non-transitory computer-readable medium storing computer executable code, comprising code for:

• scheduling a set of one or more first resource elements within a first sub-band of a slot to a scheduled entity based on a first rank and a first set of data streams assigned to the scheduled entity;
• scheduling a set of one or more second resource elements within a second sub-band of the slot to the scheduled entity based on a second rank and a second set of data streams assigned to the scheduled entity, wherein the first rank is different from the second rank and the first set of data streams is different than the second set of data streams;
• and
• transmitting scheduling information indicating the set of one or more first resource elements and the set of one or more second resource elements to the scheduled entity, the scheduling information further comprising stream identification information for each sub-band assigned to the scheduled entity within the slot.
