Claim 5:
6. An access node, for a wireless telecommunications system, comprising a memory device and a processor configured to execute instructions stored on the memory device such that when executed, cause the access node to:
receive, from a user agent (UA), within a bitmap, power headroom-related information for a number of aggregated carriers that is less than or equal to a total number of aggregated carriers,
wherein each bit in the bitmap corresponds to one of the aggregated carriers, one value in the bitmap indicating that the power headroom-related information for a corresponding carrier is being transmitted, and another value in the bitmap indicating that the power headroom-related information for a corresponding carrier is not being transmitted, and
wherein the power headroom-related information comprises one of power headroom and path loss information, for at least one of the aggregated carriers;
specify a set of carriers from the total number of aggregated carriers for which the power headroom-related information is to be reported; and
inform the UA of the set of carriers for which the power headroom-related information is to be reported.
