Dynamic transmit power adjustment

A method for operating a user equipment (UE), the method comprising:

• by the UE:
• decoding baseband configuration information received from a base station, the baseband configuration information including at least a modulation and coding scheme (MCS), resource block (RB) allocation, and carrier assignment for uplink (UL) transmission and downlink (DL) reception;
• determining a communication mode from a plurality of available communication modes based on the baseband configuration information, wherein the plurality of available communication modes include an LTE standalone (SA) communication mode, a New Radio (NR) SA communication mode, an LTE-NR dual connectivity (DC) communication mode, and an NR-NR DC communication mode;
• selecting an additional maximum power reduction (A-MPR) from at least one A-MPR look-up table (LUT) based on the baseband configuration information and the radio access technology (RAT) of the determined communication mode;
• and
• encoding in UL data for transmission to the base station via the selected communication mode and using transmit power adjusted based on the determined A-MPR.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), wherein the instructions configure the UE for dynamic transmit power adjustment and cause the UE to:

• decode baseband configuration information received from a base station, the baseband configuration information including at least a modulation and coding scheme (MCS), resource block (RB) allocation, and carrier assignment for uplink (UL) transmission and downlink (DL) reception,
• determine a communication mode from a plurality of available communication modes based on the baseband configuration information, wherein the plurality of communication modes correspond to a plurality of radio access technologies (RATs);
• determine an additional maximum power reduction (A-MPR) based on the baseband configuration information and the RAT of the determined communication mode;
• and
• encode UL data for transmission to the base station via the selected communication mode and using transmit power adjusted based on the determined A-MPR.
