SYSTEM AND METHOD FOR RADIO ACCESS NETWORK BASEBAND WORKLOAD TRAFFIC PATTERN AWARE SCHEDULING

1 . An apparatus for idle state central processing unit (CPU) core transitioning, the apparatus comprising:

at least one memory storing instructions; and

at least one processor configured to execute the instructions to:

determine a first slot of a slot pattern in which a task of a first type is scheduled to be performed;

assign at least one task of the first type to be performed by at least one first CPU core allocated to perform tasks of the first type;

determine a second slot of the slot pattern in which a task of the first type is not scheduled to be performed; and

transition the at least one first CPU from an active state to an idle state after at least the second slot of the slot pattern.

2 . The apparatus of claim 1 , wherein the second slot of the slot pattern occurs after the assigned at least one task of the first type is scheduled to be completed by the at least one first CPU.

3 . The apparatus of claim 1 , wherein the slot pattern is a time-division duplex (TDD) pattern.

4 . The apparatus of claim 1 , wherein the at least one processor is further configured to:

determine a third slot of the slot pattern in which a task of a second type is scheduled to be performed; and

assign at least one task of the second type to be performed by at least one second CPU core during the third slot of the slot pattern.

5 . The apparatus of claim 4 , wherein the at least one processor is configured to transition the at least one first CPU from the active state to the idle state while the at least one task of the second type is being performed by the at least one second CPU core.

6 . The apparatus of claim 4 , wherein the task of the first type comprises an uplink task, and

wherein the task of the second type comprises either a downlink task or a sounding reference signal (SRS) task.

7 . The apparatus of claim 4 , wherein the task of the first type comprises a downlink task, and

wherein the task of the second type comprises either an uplink task or a sounding reference signal (SRS) task.

8 . The apparatus of claim 4 , wherein the task of the first type comprises a sounding reference signal (SRS) task, and

wherein the task of the second type comprises either an uplink task or a downlink task.

9 . The apparatus of claim 1 , wherein the idle state corresponds to a C-6 long sleep idle state of the at least one first CPU core.

10 . A method for idle state central processing unit (CPU) core transitioning, the method comprising:

determining a first slot of a slot pattern in which a task of a first type is scheduled to be performed;

assigning at least one task of the first type to be performed by at least one first CPU core allocated to perform tasks of the first type;

determining a second slot of the slot pattern in which a task of the first type is not scheduled to be performed; and

transitioning the at least one first CPU from an active state to an idle state after at least the second slot of the slot pattern.

11 . The method of claim 10 , wherein the second slot of the slot pattern occurs after the assigned at least one task of the first type is scheduled to be completed by the at least one first CPU.

12 . The method of claim 10 , wherein the slot pattern is a time-division duplex (TDD) pattern.

13 . The method of claim 10 , further comprising:

determining a third slot of the slot pattern in which a task of a second type is scheduled to be performed; and

assigning at least one task of the second type to be performed by at least one second CPU core during the third slot of the slot pattern.

14 . The method of claim 13 , wherein the transitioning the at least one first CPU from the active state to the idle state is performed while the at least one task of the second type is being performed by the at least one second CPU core.

15 . The method of claim 13 , wherein the task of the first type comprises an uplink task, and

wherein the task of the second type comprises either a downlink task or a sounding reference signal (SRS) task.

16 . The method of claim 13 , wherein the task of the first type comprises a downlink task, and

wherein the task of the second type comprises either an uplink task or a sounding reference signal (SRS) task.

17 . The method of claim 13 , wherein the task of the first type comprises a sounding reference signal (SRS) task, and

wherein the task of the second type comprises either an uplink task or a downlink task.

18 . The method of claim 10 , wherein the idle state corresponds to a C-6 long sleep idle state of the at least one first CPU core.

19 . A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to:

determine a first slot of a slot pattern in which a task of a first type is scheduled to be performed;

assign at least one task of the first type to be performed by at least one first central processing unit (CPU) core allocated to perform tasks of the first type;

determine a second slot of the slot pattern in which a task of the first type is not scheduled to be performed; and

transition the at least one first CPU from an active state to an idle state after at least the second slot of the slot pattern.

20 . The apparatus of claim 1 , wherein the second slot of the slot pattern occurs after the assigned at least one task of the first type is scheduled to be completed by the at least one first CPU.
