transmitting multiple power headroom reports (PHRs) for the PUSCH repetitions associated with multiple SRS resource sets, wherein each of the multiple PHRs is associated with each of the multiple SRS resource sets based on each of the multiple panels related to multiple transmission and reception points (TRPs), respectively. ### Claim 2 (depends on 1) The method of claim 1, wherein the multiple SRS resource sets are related to the multiple panels of the UE for the PUSCH repetitions, wherein a transmission power of the PUSCH repetitions is determined to be a smaller value between a first transmission power and a second transmission power, and wherein the first transmission power is based on a maximum value of a summation of transmission power of each of the multiple panels, and the second transmission power is a precalculated transmission power based on an index of each of the multiple panels, wherein the first transmission power is based on the maximum value and a predetermined coefficient for each of the multiple panels. ### Claim 3 (depends on 2) The method of claim 2, wherein the predetermined coefficient is 1 or an inverse value of a number of activated panels of the multiple panels. ### Claim 4 (depends on 2) The method of claim 2, wherein the predetermined coefficient is configured based on information configured by a base station. ### Claim 5 (depends on 2) The method of claim 2, further comprising transmitting UE capability information, wherein the UE capability information includes information representing maximum transmission power of each of the multiple panels or information related to a coefficient to be applied to each of the multiple panels. ### Claim 6 (depends on 5) The method of claim 5, wherein the predetermined coefficient is a value determined based on the maximum transmission power of each of the multiple panels. ### Claim 7 (depends on 5) The method of claim 5, wherein the configuration information includes the predetermined coefficient, and the predetermined coefficient is a value determined based on the maximum transmission power of each of the multiple panels. ### Claim 8 (depends on 2) The method of claim 2, wherein the precalculated transmission power is determined based on a type of the uplink signal. ### Claim 9 (depends on 8) The method of claim 8, wherein, based on a condition that a summation of the precalculated transmission powers of the activated panels of the multiple panels is greater than the maximum value, the second transmission power is based on a pre-defined value. ### Claim 10 (depends on 9) The method of claim 9, wherein the pre-defined value is based on the precalculated transmission power and a scaling coefficient. ### Claim 11 (depends on 10) The method of claim 10, wherein the scaling coefficient is a value of the maximum value divided by the summation of the precalculated transmission powers. ### Claim 12 (depends on 8) The method of claim 8, wherein, based on a condition that a summation of the precalculated transmission powers of the activated panels of the multiple panels is greater than the maximum value, the second transmission power for pre-defined panels of the multiple panels is based on a pre-defined value. ### Claim 13 (depends on 12) The method of claim 12, wherein the pre-defined value is based on a greater value between panel minimum transmission power and the precalculated transmission power decreased by a predetermined value. ### Claim 14 (depends on 13) The method of claim 13, wherein the predetermined value is a value set to each panel of the pre-defined panels, and wherein a summation of the predetermined values for the pre-defined panels is equal to or smaller than the summation of the precalculated transmission powers minus the maximum value. ### Claim 15 (depends on 1) The method of claim 1, wherein the configuration information includes parameters related to the determination of the transmission power. ### Claim 16 (depends on 15) The method of claim 15, wherein the multiple SRS resource sets are related to the multiple panels of the UE for the PUSCH repetitions, wherein, based on a change of a panel, among the multiple panels, for the PUSCH repetitions, a value of the parameters is maintained as a same value before the change of the panel or changed to a value set to default. ### Claim 17 A user equipment (UE) with multiple panels in a wireless communication system, comprising: one or more transceivers; one or more processors; and one or more memories operably accessible to the one or more processors, and configured to store instructions for operations performed by the one or more processors, wherein the operations include: receiving configuration information related to physical uplink shared channel (PUSCH) repetitions; determining multiple power headroom reports (PHRs) for the PUSCH repetitions associated with multiple SRS resource sets; and transmitting the multiple PHRs, wherein each of the multiple PHRs is associated with each of the multiple SRS resource sets based on each of the multiple panels related to multiple transmission and reception points (TRPs), respectively. ### Claim 18 One or more non-transitory computer readable medium for storing one or more commands, wherein the one or more commands executable by one or more processors are configured for a user equipment (UE) with multiple panels to perform operations comprising: receiving configuration information related to physical uplink shared channel (PUSCH) repetitions; determining multiple power headroom reports (PHRs) for the PUSCH repetitions associated with multiple SRS resource sets; and transmitting the multiple PHRs, wherein each of the multiple PHRs is associated with each of the multiple SRS resource sets based on each of the multiple panels related to multiple transmission and reception points (TRPs), respectively.
