Abstract

The invention discloses a method for reporting power headroom information to a base station side in a user side with a carrier aggregation system. The user side is configured with 32 component carriers at most, and slave cells are possible to be configured with physical uplink control channels (PUCCHs), each component carrier is corresponding to one cell, and the power headroom information indicates channel power headroom of at least one cell. The method comprises the step that A, the user side sets one of a plurality of power headroom report MAC control unit formats to report the power headroom information to the base station side. In addition, the invention also discloses a method for reporting the power headroom information to the base station side in the user side with the carrier aggregation system, wherein the user side is configured with 5 component carriers at most, and slave cells are possible to be configured with PUCCHs.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, the present invention relates to a method for reporting power headroom information to a base station in a user end of a carrier aggregation system. Background technique [0002] In the enhanced carrier aggregation system Rel-13, for UEs using carrier aggregation, it has been agreed to support physical uplink control channel (PUCCH) configuration on the secondary cell, and up to 32 carriers can be supported. These two characteristics will require that the Power Headroom Report (PHR) be enhanced accordingly. [0003] In the past carrier aggregation system, the power headroom reporting process is used to provide the serving base station with the difference between the maximum nominal transmission power of the user and the estimated power of the UL-SCH transmission of each activated Scell, And provide the difference between the maximum nominal transmission power of th...
