Abstract:
The present application discloses a method and device for transmitting and receiving a power headroom report, wherein the method for transmitting a power headroom report comprises: forming, at a user equipment, a power headroom report specific to each carrier component; and transmitting the power headroom report to a base station. By implementing the method and device disclosed by the present application, a complete power headroom reporting mechanism can be provided to a LTE-A system having multiple new features. In addition, by receiving the power headroom report specific to each carrier component, the base station can further derive how many resource units need to be allocated to the user equipment, and a corresponding modulation and coding scheme so as to perform an effective resource scheduling and guarantee transmission quality of wireless links.
