Reporting power headroom for aggregated carriers

摘要

A method for reporting power headroom-related information for a plurality of aggregated carriers. The method includes reporting in a bitmap the power headroom-related information for a number of the aggregated carriers that is less than or equal to the total number of aggregated carriers, wherein the power headroom-related information is one of a power headroom for at least one of the aggregated carriers and a path loss for at least one of the aggregated carriers.

1. A method implemented in a user agent comprising a processor and a memory device storing instructions executable by the processor to implement the method, the method comprising:
transmitting in a media access control (MAC) control element power headroom-related information for a number of a plurality of aggregated carriers that is less than or equal to a total number of the aggregated carriers, the aggregated carriers comprising a first carrier and a second carrier; and transmitting in the MAC control element a bitmap, each of the aggregated carriers corresponding to a bit in the bitmap, a first value in the bitmap indicating that the power headroom-related information for the first carrier is included in the MAC control element, and a second value in the bitmap indicating that the power headroom-related information for the second carrier is not included in the MAC control element.
