Method for reporting power headroom report and user equipment

摘要

The present invention discloses a method for reporting a power headroom report and a user equipment, which are applied in the field of communications. The method includes triggering reporting of a first power headroom report and determining that a condition of sending the first power headroom report is satisfied. The condition of sending the first power headroom report includes a determination that uplink data channel transmission occurs in a current transmission time interval. The first power headroom report is obtained. The first power headroom report includes a first power headroom value that includes a difference between maximum transmitting power of a carrier and a sum of transmitting power of a control channel of the carrier and transmitting power of a data channel of the carrier.

1. A method for reporting a power headroom report, the method comprising:
triggering reporting of a first power headroom report; determining that a condition of transmitting the first power headroom report is satisfied, wherein the condition of transmitting the first power headroom report comprises a determination that uplink data channel transmission occurs in a current transmission time interval; obtaining the first power headroom report and a second power headroom report, wherein the first power headroom report comprises a first power headroom value that comprises a difference between maximum transmitting power of a carrier and a sum of transmitting power of a control channel of the carrier and transmitting power of a data channel of the carrier, and the second power headroom report comprises a second power headroom value that comprises a difference between the maximum transmitting power of the carrier and the transmitting power of the data channel of the carrier; instructing a multiplexing entity to use the same Medium Access layer control element (MAC CE) to transmit the first power headroom report and the second power headroom report of the carrier in the current transmission time interval; and transmitting the first power headroom report and the second power headroom report of the carrier in the current transmission time interval using the same MAC CE.
