1. A method for power management by a user equipment (UE) in an uplink transmission, the method comprising:
determining, at the UE, whether feedback related to a transmit power of the UE, from a network entity, is available;
determining 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;
evaluating 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;
determining a plurality of second transmit power, each of the plurality of second transmit power 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;
evaluating 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;
determining a spectral efficiency among the first and the plurality of second spectral efficiencies; and
transmitting 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 determined spectral efficiency.
