Patent ID: 8693362

Claim:
A method of reporting power headroom from a mobile device, the method comprising: identifying a transmit power associated with each of a plurality of independently power controlled channels on which the mobile device is configured to transmit concurrently, the identifying a transmit power including: determining transmit power during a given time period for a first independently power controlled channel to identify a first transmit power, if the mobile device is transmitting on the first independently power controlled channel during the given time period; and attributing a transmission-format-independent transmit power to a second independently power controlled channel, if the mobile device does not transmit on the second independently power controlled channel during the given time period, wherein the transmission-format-independent transmit power is a non-zero value that corresponds to a representation of transmit power for a channel, and which is attributed to the channel when the channel is not being transmitted by the mobile device; and transmitting a headroom report based on the identified transmit powers for the mobile device.
