Abstract
The disclosure discloses a reporting method, device and system for a Power Headroom Report (PHR) in dual connectivity. A first Evolved Node B (eNB) and a second eNB establish split Data Radio Bearers (DRBs) with a User Equipment (UE), and transmit an indication for indicating change in uplink transmission to the UE; the UE determines the change in the uplink transmission of the split DRBs, and triggers and reports the PHR to the first eNB and/or the second eNB according to the change in the uplink transmission respectively; and the first eNB and/or the second eNB receive/receives the PHR reported by the UE respectively. The disclosure also discloses the reporting device and system for the PHR in the dual connectivity.
