Abstract
Embodiments relate to the field of wireless communications, and particularly, to methods and apparatuses for power headroom reporting. In one embodiment, a method of power headroom reporting includes: determining PH information of each of configured and active cells at a current instant if PH information is required to be reported, where the configured and active cells include a cell which is configured with a downlink subframe at the current instant; and reporting the determined PH information. Since a power headroom is reported by obtaining PH information of a configured and active cell which is currently a downlink subframe according to a virtual transmission format, the PH information facilitates subsequent scheduling by an eNB.
