6. An apparatus for power headroom reporting, comprising: a processor, a memory and a network interface, wherein the processor is configured to:
receive, through the network interface, a Radio Resource Control (RRC) signaling from the network device; wherein an information element (IE) of the RRC signaling comprises a transmit power limit of a terminal device in a cell group; wherein the transmit power limit is used for obtaining a power headroom report based on a first configured maximum transmit power that is determined based on the transmit power limit of the terminal device in the cell group; determine, according to a preset rule, to obtain a power headroom report based on a second configured maximum transmit power of the terminal device in the cell group in a case that uplink transmission of the terminal device on the cell group overlaps with a semi-statically configured downlink symbol of another cell group, or in a case that uplink transmission of the terminal device on the cell group does not overlap with uplink transmission on the another cell group, wherein the transmit power limit of the terminal device in the cell group is not taken into account when the second configured maximum transmit power is calculated, wherein the cell group comprises a Master Cell Group, or a Secondary Cell Group; and
report, through the network interface, the power headroom report;
wherein the power headroom report comprises a second power headroom and the second configured maximum transmit power, the second power headroom is obtained based on the second configured maximum transmit power.
