Methods and systems for power management in an uplink transmission

A method for power management by a user equipment (UE) in an uplink transmission, the method comprising:

• determining a power transmission level (MTPL) of the UE;
• determining whether a total transmit power for a plurality of transmission paths of the UE is less than the MTPL;
• in response to determining that the total transmit power is less than the MTPL, the method comprises:
• splitting the MTPL equally into at least two of a first transmit power and a second transmit power among the plurality of transmission paths, wherein a first transmit power corresponds to a first transmission path and the second transmit power corresponds to a second transmission path among the plurality of transmission paths;
• determining a revised first MTPL, if the first transmit power is greater than a first MTPL and second transmit power is less than a second MTPL, wherein the first MTPL corresponds to the power transmission level of first transmission path and the second MTPL corresponds to the power transmission level of second transmission path;
• and
• determining a revised second MTPL, if the first transmit power is less than the first MTPL and the second transmit power is greater than the second MTPL.

A system for power management by a user equipment (UE) in an uplink transmission, the system comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• determine, at the UE, whether feedback related to a transmit power of the UE, from a network entity is available;
• determine a first transmit power of the UE based on the determination and at least one of a plurality of transmitting parameters associated with the UE;
• evaluate a first spectral efficiency of the UE upon transmitting data at the first transmit power in a predefined time duration, using a plurality of predefined parameters;
• determine a plurality of second transmit powers, each of the plurality of second transmit powers determined based on at least one of:
• an increment and decrement from the first transmit power, and the plurality of transmitting parameters associated with the UE;
• evaluate a plurality of second spectral efficiencies corresponding to the plurality of second transmit power for the predefined time duration upon transmitting the data at the plurality of second transmit power;
• determine a spectral efficiency among the first and the plurality of second spectral efficiencies;
• and
• transmit the data at a final transmit power among the first and the second plurality of second spectral efficiencies, wherein the final transmit power corresponds to the spectral efficiency.
