Abstract
Methods and apparatus for power control are described. Methods are included for calculating and signaling power control related data to support multiple component carriers (CCs) for which transmission may be accomplished with one or more WTRU power amplifiers (PAs). Methods are included for calculating and signaling one or more of CC-specific power control related data and PA-specific power control related data. The power control related data may include one or more of maximum power, power headroom, and transmit power. Methods for selecting which power control related data to exchange are included. Methods are included for calculating and signaling power control related data for physical UL shared channel (PUSCH), physical UL control channel (PUCCH), and simultaneous PUSCH and PUCCH transmission.
