METHODS AND APPARATUSES FOR POWER CONTROL ENHANCEMENT

1 . A method performed by a User Equipment (UE) for power control enhancement, the method comprising:

determining a first power state based on a first evaluation period;

determining a second power state, which is associated with a new transmission, based on a second evaluation period;

determining whether a power state change has occurred by comparing the first power state with the second power state; and

in response to determining that the power state change for the new transmission has occurred, triggering a Power Headroom Report (PHR) procedure.

2 . The method of claim 1 , further comprising:

transmitting, to a Base Station (BS), an indication indicating that the UE supports transmissions under a Carrier Aggregation (CA) architecture across different frequency bands with different power classes.

3 . The method of claim 1 , further comprising:

transmitting, to a Base Station (BS), an indication indicating a maximum average percentage of symbols, during an Uplink (UL) duty cycle, that are permitted to be scheduled for a UL transmission at an increased power.

4 . The method of claim 1 , further comprising:

transmitting a PHR using the new transmission in response to triggering the PHR procedure; and

starting a prohibit timer in response to transmitting the PHR,

wherein the UE is prohibited from transmitting another PHR while the prohibit timer is running.

5 . The method of claim 1 , further comprising:

receiving, from a Base Station (BS), an indication indicating that the UE is allowed to trigger the PHR procedure in response to determining that the power state change has occurred.

6 . The method of claim 1 , wherein:

the first evaluation period includes one or more first Uplink (UL) transmissions prior to the new transmission, and

the second evaluation period includes the new transmission.

7 . The method of claim 6 , wherein the first evaluation period further includes a second UL transmission after the new transmission.

8 . The method of claim 7 , further comprising:

receiving, in a Physical Downlink Control Channel (PDCCH) monitoring occasion, a first Downlink Control Information (DCI) format that schedules the new transmission; and

receiving, in the same PDCCH monitoring occasion, a second DCI format that schedules the second UL transmission.

9 . A User Equipment (UE) for power control enhancement, the UE comprising:

at least one processor; and

at least one non-transitory computer-readable medium coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:

determine a first power state based on a first evaluation period;

determine a second power state, which is associated with a new transmission, based on a second evaluation period;

determine whether a power state change has occurred by comparing the first power state with the second power state; and

in response to determining that the power state change for the new transmission has occurred, trigger a Power Headroom Report (PHR) procedure.

10 . The UE of claim 9 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

transmit, to a Base Station (BS), an indication indicating that the UE supports transmissions under a Carrier Aggregation (CA) architecture across different frequency bands with different power classes.

11 . The UE of claim 9 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

transmit, to a Base Station (BS), an indication indicating a maximum average percentage of symbols, during an Uplink (UL) duty cycle, that are permitted to be scheduled for a UL transmission at an increased power.

12 . The UE of claim 9 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

transmit a PHR using the new transmission in response to triggering the PHR procedure; and

start a prohibit timer in response to transmitting the PHR,

wherein the UE is prohibited from transmitting another PHR while the prohibit timer is running.

13 . The UE of claim 9 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

receive, from a Base Station (BS), an indication indicating that the UE is allowed to trigger the PHR procedure in response to determining that the power state change has occurred.

14 . The UE of claim 9 , wherein:

the first evaluation period includes one or more first Uplink (UL) transmissions prior to the new transmission, and

the second evaluation period includes the new transmission.

15 . The UE of claim 14 , wherein the first evaluation period further includes a second UL transmission after the new transmission.

16 . The UE of claim 15 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

receive, in a Physical Downlink Control Channel (PDCCH) monitoring occasion, a first Downlink Control Information (DCI) format that schedules the new transmission; and

receive, in the same PDCCH monitoring occasion, a second DCI format that schedules the second UL transmission.
