Abstract

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. According to one embodiment of the present disclosure, a method performed by a terminal in a communication system is provided. The method comprises: receiving power headroom reporting (PHR)-related configuration information; confirming at least one PHR based on the PHR-related configuration information; and transmitting the at least one PHR, wherein the at least one PHR comprises one of PHR for an actual physical uplink shared channel (PUSCH) related to a first resource index, and PHR for a reference PUSCH related to the first resource index, and, if a PUSCH related to the first resource index is transmitted in slot n, then the PHR for the actual PUSCH related to the first resource index is for a first PUSCH related to the first resource index overlapping with slot n.

First claim

1 . A method performed by a terminal in a communication system, the method comprising:
receiving power headroom reporting (PHR) related configuration information; identifying at least one PHR based on the PHR related configuration information; and transmitting the at least one PHR, wherein the at least one PHR comprises one of a PHR for an actual physical uplink shared channel (PUSCH) associated with a first resource index and a PHR for a reference PUSCH associated with the first resource index, and wherein in the case that a PUSCH associated with the first resource index is transmitted in a slot n, the PHR for the actual PUSCH associated with the first resource index is for a first PUSCH associated with the first resource index overlapped with the slot n.

2 . The method of claim 1 ,
wherein the at least one PHR comprises a PHR for an actual PUSCH associated with the first resource index, wherein in the case that a PUSCH associated with a second resource index is transmitted in the slot n, the at least one PHR further comprises a PHR for an actual PUSCH associated with the second resource index overlapped with the slot n, and wherein in the case that a PUSCH associated with the second resource index is not transmitted in the slot n, the at least one PHR further comprises a PHR for a reference PUSCH associated with the second resource index.

3 . The method of claim 1 , wherein the at least one PHR comprises a PHR for a reference PUSCH associated with the first resource index and a PHR for a reference PUSCH associated with a second resource index.

4 . A method performed by a base station in a communication system, the method comprising:
transmitting configuration information power headroom reporting (PHR) related configuration information; and receiving at least one PHR, wherein the at least one PHR is based on the PHR related configuration information, wherein the at least one PHR comprises one of a PHR for an actual physical uplink shared channel (PUSCH) associated with a first resource index and a PHR for a reference PUSCH associated with the first resource index, and wherein in the case that a PUSCH associated with the first resource index is transmitted in a slot n, the PHR for the actual PUSCH associated with the first resource index is for a first PUSCH associated with the first resource index overlapped with the slot n.

5 . The method of claim 4 ,
wherein the at least one PHR comprises a PHR for an actual PUSCH associated with the first resource index, wherein in the case that a PUSCH associated with a second resource index is transmitted in the slot n, the at least one PHR further comprises a PHR for an actual PUSCH associated with the second resource index overlapped with the slot n, and wherein in the case that a PUSCH associated with the second resource index is not transmitted in the slot n, the at least one PHR further comprises a PHR for a reference PUSCH associated with the second resource index.

6 . The method of claim 4 , wherein the at least one PHR comprises a PHR for a reference PUSCH associated with the first resource index and a PHR for a reference PUSCH associated with a second resource index.

7 . A terminal of a communication system, the terminal comprising:
a transceiver; and a controller coupled with the transceiver and configured to:
receive power headroom reporting (PHR) related configuration information,
identify at least one PHR based on the PHR related configuration information, and
transmit the at least one PHR,
wherein the at least one PHR comprises one of a PHR for an actual physical uplink shared channel (PUSCH) associated with a first resource index and a PHR for a reference PUSCH associated with the first resource index, and wherein in the case that a PUSCH associated with the first resource index is transmitted in a slot n, the PHR for the actual PUSCH associated with the first resource index is for a first PUSCH associated with the first resource index overlapped with the slot n.

8 . The terminal of claim 7 ,
wherein the at least one PHR comprises a PHR for an actual PUSCH associated with the first resource index, wherein in the case that a PUSCH associated with a second resource index is transmitted in the slot n, the at least one PHR further comprises a PHR for an actual PUSCH associated with the second resource index overlapped with the slot n, and wherein in the case that a PUSCH associated with the second resource index is not transmitted in the slot n, the at least one PHR further comprises a PHR for a reference PUSCH associated with the second resource index.

9 . The terminal of claim 7 , wherein the at least one PHR comprises a PHR for a reference PUSCH associated with the first resource index and a PHR for a reference PUSCH associated with a second resource index.

10 . A base station of a communication system, the base station comprising:
a transceiver; and a controller coupled with the transceiver and configured to:
transmit power headroom reporting (PHR) related configuration information, and
receive at least one PHR,
wherein the at least one PHR is based on the PHR related configuration information, wherein the at least one PHR comprises one of a PHR for an actual physical uplink shared channel (PUSCH) associated with a first resource index and a PHR for a reference PUSCH associated with the first resource index, and wherein in the case that a PUSCH associated with the first resource index is transmitted in a slot n, the PHR for the actual PUSCH associated with the first resource index is for a first PUSCH associated with the first resource index overlapped with the slot n.

11 . The base station of claim 10 ,
wherein the at least one PHR comprises a PHR for an actual PUSCH associated with the first resource index, wherein in the case that a PUSCH associated with a second resource index is transmitted in the slot n, the at least one PHR further comprises a PHR for an actual PUSCH associated with the second resource index overlapped with the slot n, and wherein in the case that a PUSCH associated with the second resource index is not transmitted in the slot n, the at least one PHR further comprises a PHR for a reference PUSCH associated with the second resource index.

12 . The base station of claim 10 , wherein the at least one PHR comprises a PHR for a reference PUSCH associated with the first resource index and a PHR for a reference PUSCH associated with a second resource index.
