Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus maintains at least one PHR trigger for triggering communication of a PHR for a plurality of component carriers. In addition, the apparatus communicates the PHR for at least one of the component carriers upon the at least one PHR trigger being triggered. The communicated PHR may be an aggregated PHR that includes power headroom information on the PCC and activated SCCs. The communicated PHR may further include an index associating information in the PHR to a corresponding component carrier. The communicated PHR may further include information indicating use of a PUSCH reference for computing the PHR for the at least one of the component carriers on which there is no PUSCH transmission.
