Abstract: A computer system includes a host and a storage device. The host provides an input/output request (IO request).

The computer system may adaptively control interrupt generation of the storage device based on a load status of a CPU or the number of delayed IOs. The interrupt generation of the storage device may be adjusted to obtain a CPU gain without loss of performance or processing time of the computer system.

If the PUSCH is transmitted outside the LA window, the first transmit power of the PUSCH is derived without using the second transmit power of the physical uplink channel of the second cell group.
