Abstract

Provided is a method performed by a user equipment (UE) in a wireless communication system, the method including receiving, from a base station, higher layer configuration information including information associated with a sounding reference signal (SRS) resource set and downlink control information (DCI) including scheduling information for a physical uplink shared channel (PUSCH), identifying, from the DCI, a plurality of SRS resource indicators (SRIs) for PUSCH repetition in case that two SRS resource sets are configured by the information associated with the SRS resource set, identifying an SRS resource for the PUSCH repetition based on the plurality of SRIs, determining a power headroom report (PHR) between a first PHR based on actual transmission and a second PHR based on a reference format configured from the higher layer configuration information, and transmitting the determined PHR on the PUSCH.

Dependent claims

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

receiving, from a base station, sounding reference signal (SRS) configuration information including a first SRS resource set and a second SRS resource set;
receiving, from the base station, downlink control information (DCI) including a plurality of SRS resource indicators (SRIs) for physical uplink shared channel (PUSCH) repetition, wherein the plurality of SRIs includes a first SRI associated with the first SRS resource set and a second SRI associated with the second SRS resource set;
determining a power headroom report (PHR) for multiple transmit reception point (TRP) including a first PH related to the first SRS resource set and a second PH related to the second SRS resource set;
and
transmitting a multiple TRP medium access control control element (MAC CE) including the determined PHR on a PUSCH based on the DCI,
wherein the determining of the PHR for multiple TRP comprises:
identifying whether a first PUSCH transmission related to the first PH and a second PUSCH transmission related to the second PHR is overlapped with a slot in which the PUSCH including the MAC CE is transmitted;
in case that the first PUSCH transmission is overlapped with the slot, determining the first PH based on an actual transmission;
in case that the first PUSCH transmission is not overlapped with the slot, determining the first PH based on a reference format;
in case that the second PUSCH transmission is overlapped with the slot, determining the second PH based on the actual transmission;
and
in case that the second PUSCH transmission is not overlapped with the slot, determining the second PH based on a reference format.

9 more elements

A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver;
and
at least one processor operably coupled to the transceiver, wherein the at least one processor is configured to:
receive, from a base station, sounding reference signal (SRS) configuration information including a first SRS resource set and a second SRS resource set;
receive, from the base station, downlink control information (DCI) including a plurality of SRS resource indicators (SRIs) for physical uplink shared channel (PUSCH) repetition, wherein the plurality of SRIs includes a first SRI associated with the first SRS resource set and a second SRI associated with the second SRS resource set;
determine a power headroom report (PHR) for multiple transmit reception point (TRP) including a first PH related to the first SRS resource set and a second PH related to the second SRS resource set;
and
transmit a multiple TRP medium access control control element (MAC CE) including the determined PHR on a PUSCH based on the DCI,
wherein the at least one processor is further configured to:
identify whether a first PUSCH transmission related to the first PH and a second PUSCH transmission related to the second PHR is overlapped with a slot in which the PUSCH including the MAC CE is transmitted,
in case that the first PUSCH transmission is overlapped with the slot, determine the first PH based on an actual transmission,
in case that the first PUSCH transmission is not overlapped with the slot, determine the first PH based on a reference format,
in case that the second PUSCH transmission is overlapped with the slot, determine the second PH based on the actual transmission, and
in case that the second PUSCH transmission is not overlapped with the slot, determine the second PH based on a reference format.
