Abstract
A method of a user equipment (UE) to report a power headroom (PH) in a wireless communication system includes receiving configuration information related to the power headroom (PH), and transmitting a message for a report of the PH. The report of the PH is triggered based on a pre-configured event, and the message for the report of the PH includes information related to P-MPR (Power management-Maximum Power Reduction). The information related to the P-MPR includes one or more values related to the PH, and the one or more values related to the PH are related to one or more specific indexes.
Claims6
A method comprising:
- receiving, by a user equipment (UE) from a base station, configuration information related to a power headroom (PH);
- and
- based on a Power Headroom Report (PHR) being triggered, transmitting, by the UE to the base station, a PHR Medium Access Control Control Element (PHR MAC CE),
- wherein the PHR is triggered based on an event that occurs based on a threshold related to maximum permissible exposure (MPE),
- wherein the PHR MAC CE includes information related to Power management-Maximum Power Reduction (P-MPR),
- wherein the information related to the P-MPR includes one or more values which are related to a power backoff to meet MPE requirements,
- wherein the one or more values are related to one or more specific indexes,
- wherein the method further comprises:
- transmitting, by the UE to the base station, channel state information (CSI) that includes information related to Sounding Reference Signal (SRS) resource sets,
- wherein the SRS resource sets are related to panels determined by a condition related to the MPE and the panels include at least one preferred panel and/or at least one non-preferred panel.
7 more elements
A user equipment (UE) comprising:
- one or more transceivers;
- one or more processors configured to control the one or more transceivers;
- and
- one or more memories operably connected to the one or more processors,
- wherein the one or more memories store instructions, that are configured to allow the one or more processors to perform operations, based on being executed by the one or more processors,
- wherein the operations comprise:
- receiving configuration information related to a power headroom (PH);
- and
- based on a Power Headroom Report (PHR) being triggered, transmitting a PHR Medium Access Control Control Element (PHR MAC CE),
- wherein the PHR is triggered based on an event that occurs based on a threshold related to maximum permissible exposure (MPE),
- wherein the PHR MAC CE includes information related to Power management-Maximum Power Reduction (P-MPR),
- wherein the information related to the P-MPR includes one or more values which are related to a power backoff to meet MPE requirements,
- wherein the one or more values are related to one or more specific indexes,
- wherein the operations further comprises:
- transmitting, to a base station, channel state information (CSI) that includes information related to Sounding Reference Signal (SRS) resource sets,
- wherein the SRS resource sets are related to panels determined by a condition related to the MPE and the panels include at least one preferred panel and/or at least one non-preferred panel.
13 more elements
A base station comprising:
- one or more transceivers;
- one or more processors configured to control the one or more transceivers;
- and
- one or more memories operably connected to the one or more processors,
- wherein the one or more memories store instructions, that are configured to allow the one or more processors to perform operations, based on being executed by the one or more processors,
- wherein the operations comprise:
- transmitting, to a user equipment (UE), configuration information related to a power headroom (PH);
- and
- based on a Power Headroom Report (PHR) being triggered, receiving, from the UE, a PHR Medium Access Control Control Element (PHR MAC CE),
- wherein the PHR is triggered based on an event that occurs based on a threshold related to maximum permissible exposure (MPE),
- wherein the PHR MAC CE includes information related to Power management-Maximum Power Reduction (P-MPR),
- wherein the information related to the P-MPR includes one or more values which are related to a power backoff to meet MPE requirements,
- wherein the one or more values are related to one or more specific indexes,
- wherein the operations further comprises:
- receiving, from the UE, channel state information (CSI) that includes information related to Sounding Reference Signal (SRS) resource sets,
- wherein the SRS resource sets are related to panels determined by a condition related to the MPE and the panels include at least one preferred panel and/or at least one non-preferred panel.
