wherein the first value is based on accumulation of transmit power control (TPC) commands transmitted within the first time domain window.

10. The BS of claim 9 , wherein:

the transceiver is further configured to transmit one or more TPC commands after an end of the first time domain window and a start of the second time domain window, and

wherein the second power control adjustment state is further based on a second value obtained by accumulating the one or more TPC commands.

11. The BS of claim 9 , wherein:

the TPC commands are provided by a downlink control information (DCI) format that does not schedule the uplink channel, and

a TPC command associated with the first power control adjustment state is provided by a DCI format that schedules the uplink channel.

12. The BS of claim 9 , wherein:

the transceiver is further configured to transmit a message for configuring a demodulation reference signal (DM-RS) bundling, and

wherein in case that the DM-RS bundling is configured, power consistency and phase continuity are maintained within the first time domain window.

13. The BS of claim 9 , wherein:

the uplink channel is a physical uplink shared channel (PUSCH) with a transport block (TB) processing over multiple slots, and

a start of the first time domain window is a slot where a first part of the TB is transmitted.

14. The BS of claim 9 , wherein:

the first time domain window is within first frequency resources, and

the second time domain window is within second frequency resources.

15. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting an uplink channel with repetitions based on a first power within a first time domain window, wherein the first power is determined based on a first power control adjustment state;

determining a first value by accumulating transmit power control (TPC) commands received within the first time domain window;

determining a second power control adjustment state based on the first power control adjustment state and the first value;

determining a second power based on the second power control adjustment state; and

transmitting the uplink channel with repetitions based on the second power within a second time domain window.

16. The method of claim 15 , further comprising:

receiving one or more TPC commands after an end of the first time domain window and a start of the second time domain window; and

obtaining a second value by accumulating the one or more TPC commands,
