Abstract

Embodiments of the present invention provide a PHR reporting method and user equipment. The method includes: determining power control related parameters of one or more uplink carriers of the UE; The trigger condition triggers the reporting of PHR, which can report PHR separately for multiple uplink carriers configured in the same cell, thereby assisting the network side to better control the transmit power on different carriers, saving the UE's uplink transmit power, and can also reduce Interference caused by UE uplink transmission.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method for reporting a Power Headroom Report (PHR) and user equipment. Background technique [0002] (1) Introduction to the activation and deactivation status of the carrier aggregation (Carrier Aggregation, CA) cell: [0003] When the user equipment (User Equipment, UE) is configured with CA, it includes multiple cells: one primary cell (PrimaryCel, PCell) and one or more secondary cells (Secondary Cell, SCell). [0004] In the current CA configuration, one downlink carrier will have one corresponding uplink carrier. [0005] (2) Introduction to Dual Connectivity (DC): [0006] When the UE is configured with a DC, the UE may be configured with multiple cell groups: a master cell group (Master Cell Group, MCG) and a secondary cell group (Secondary Cell Group, SCG). [0007] Wherein, the MCG includes 1 PCell and 0 or more SCells, and the SC...
