Method of power control for uplink transmission

An apparatus, comprising:

• a non-transitory memory comprising instructions;
• and
• one or more processors in communications with the non-transitory memory, wherein the one or more processors are configured to execute the instructions to:
• obtain information of an association between sounding reference signal (SRS) resource indication information and a plurality of power control parameters, the plurality of power control parameters comprising a physical uplink shared channel (PUSCH) initial target power, a pathloss, a pathloss compensation factor, and a transmit power command (TPC);
• obtain the SRS resource indication information;
• determine a value of the PUSCH initial target power, a value of the pathloss, a value of the pathloss compensation factor, and a value of the TPC based on the association and the SRS resource indication information;
• determine a transmission power of a PUSCH in accordance with the value of the PUSCH initial target power, the value of the pathloss, the value of the pathloss compensation factor, and the value of the TPC;
• and
• transmit the PUSCH using the transmission power.

A non-transitory computer-readable medium storing computer instructions, that when executed by one or more processors, cause a user equipment to perform the steps of:

• obtaining information of an association between sounding reference signal (SRS) resource indication information and a plurality of power control parameters, the plurality of power control parameters comprising a physical uplink shared channel (PUSCH) initial target power, a pathloss, a pathloss compensation factor, and a transmit power command (TPC);
• obtaining the SRS resource indication information;
• determining a value of the PUSCH initial target power, a value of the pathloss, a value of the pathloss compensation factor, and a value of the TPC based on the association and the obtained SRS resource indication information;
• determining a transmission power of a PUSCH in accordance with the value of the PUSCH initial target power, the value of the pathloss, the value of the pathloss compensation factor, and the value of the TPC;
• and
• transmitting the PUSCH using the transmission power.
