Method and Apparatus for Power Control

An apparatus, comprising:

• at least one non-transitory computer-readable medium having computer executable instructions stored therein;
• at least one receiver;
• at least one transmitter;
• and
• at least one processor coupled to the at least one non-transitory computer-readable medium, the at least one receiver and the at least one transmitter;
• wherein the computer executable instructions are programmed to cause the at least one apparatus to:
• cause the processor to select a power control scheme from at least one of an open loop power control scheme, a first closed loop power control scheme, a second closed loop power scheme with power ramping step selection, a third closed loop power scheme with scaling factor to power adjustment indicator, or a fourth closed loop power scheme with later uplink signal corresponding power adjustment indicator adoption;
• cause the processor determine a transmission power according to the selected power control scheme;
• and
• cause the transmitter to transmit an uplink signal based on the determined transmission power.

A user equipment (UE) comprising:

• a transceiver;
• and
• a processor coupled to the transceiver, the processor and the transceiver configured to cause the UE to:
• select a power control scheme from at least one of an open loop power control scheme, a first closed loop power control scheme, a second closed loop power scheme with power ramping step selection, a third closed loop power scheme with scaling factor to power adjustment indicator, or a fourth closed loop power scheme with later uplink signal corresponding power adjustment indicator adoption;
• determine a transmission power according to the selected power control scheme;
• and
• transmit an uplink signal based on the determined transmission power.
