1. A method in a wireless communication terminal that supports aggregated carrier access, the method comprising:
- receiving carrier control information for a first carrier;
determining power headroom for the first carrier based on carrier control information,determining power headroom for at least one additional carrier based on the carrier control information,transmitting a power headroom report based on the first power headroom of the first carrier and the second power headroom of the at least one additional carrier.

12. A wireless communication terminal that supports a plurality of transmitters, the terminal comprising:
-
determining a first power headroom for a first transmitter based on a control information for the first transmitter, determining a second power headroom for at least one additional transmitter based on the first transmitter control information, transmitting a power headroom report based on one or more of power headroom of the first transmitter and the power headroom of the at least one additional transmitter. - View Dependent Claims (13)

14. A wireless communication terminal that supports aggregated carrier access, the terminal comprising:
-
a transceiver; a controller coupled to the transceiver, the controller configured to determine a first power headroom for the first carrier based on a first carrier resource allocation received at the transceiver, the controller configured to determine a second power headroom for at least one additional carrier based on the first carrier resource allocation, and the controller configure to cause the transceiver to transmit a power headroom report based on the first power headroom of the first carrier and the second power headroom of the at least one additional carrier. - View Dependent Claims (15, 16, 17, 18, 19)

20. A wireless communication terminal that supports aggregated carrier access, the terminal comprising:
-
a transceiver; a processor coupled to the transceiver, the processor configured to determine a first power headroom for a first carrier, the processor configured to determine a second power headroom for at least one additional carrier, the wireless communication terminal configured to transmit a power headroom report including the first power headroom of the first carrier and the second power headroom of the at least one additional carrier if a change in a channel metric of the first carrier or the at least one additional carrier satisfies a condition. - View Dependent Claims (21, 22)
