Extension of power headroom reporting and trigger conditions
DCFirst Claim
1. An apparatus, comprising:
- a processor configured to determine a power headroom report; and
a transmitter configured to transmit the headroom report,wherein the processor is configured to determine the power headroom report with both positive and negative values of power headroom, as applicable, in which negative values indicate the missing power in dB to fulfill transmission requirements, andwherein the processor is configured to determine the power headroom by subtracting the nominal maximum transmission power and the power that the apparatus would use if it did not apply maximum power limitations, wherein the result of said subtracting is not limited to zero and positive values.

Abstract
A method can include determining a power headroom report, and transmitting the headroom report. The power headroom report can provide both positive and negative values of power headroom according to the determination, in which negative values indicate the missing power in dB to fulfill requirements, such as those given by current resource allocation and modulation and coding scheme. This method can be implemented by encoding instructions for performing this method on a computer-readable medium, such that the instructions when execute cause the computer to execute the method as a computer process. The method can further include receiving a power headroom report. The method can additionally include allocating radio network resources based on the power headroom report.
