System and methods for fast power headroom reporting

A user equipment (UE), comprising:

• a memory;
• and
• a processor in communication with the memory;
• wherein the processor is configured to:
• determine, at the UE, to change one or more beamforming parameters for transmissions on a new beam;
• determine a power headroom applicable to a transmission from the UE on the new beam;
• and
• transmit, in response to the change, a power headroom report based on the power headroom, the power headroom report being transmitted on resources assigned for the power headroom report.

A user equipment, comprising:

• means for determining, at a user equipment (UE), to change one or more beamforming parameters for transmissions on a new beam;
• means for determining a power headroom applicable to a transmission from the UE on the new beam;
• and
• means for transmitting, in response to the change, a power headroom report based on the power headroom, the power headroom report being transmitted on resources assigned for the power headroom report.

A computer-readable medium storing computer code executable by a processor of a user equipment (UE) for wireless communications, comprising code to:

• determine, at the UE, to change one or more beamforming parameters for transmissions on a new beam;
• determine a power headroom applicable to a transmission from the UE on the new beam;
• and
• transmit, in response to the change, a power headroom report based on the power headroom, the power headroom report being transmitted on resources assigned for the power headroom report.
