Abstract
The present application relates to the field of wireless communications. Disclosed in an embodiment of the present application are a method and device for reporting power headroom (PH) under carrier aggregation, for solving the problem of how to report PH when a terminal supports the transmission of a physical uplink control channel (PUCCH) on different uplink carriers corresponding to different carrier groups. In the present application, a terminal generates a Type 1 PH and a Type 2 PH for each of multiple PUCCH-transmitting uplink carriers requiring PH reporting, generates a Type 1 PH for each non-PUCCH-transmitting uplink carrier requiring PH reporting, and reports each generated Type 1 PH and Type 2 PH to a network side in the current uplink subframe. The present application solves the above problem.
