US 9,756,583 B2 · Method and terminal for transmitting power headroom report in dual connection between terminal and base station

Abstract

One disclosure of the present specification provides a method for receiving downlink data in a wireless communication system supporting 256 QAM. The method for receiving downlink data in a wireless communication system supporting 256 QAM comprises the steps of: receiving configuration information about power back-off; receiving downlink data transmitted on the basis of the configuration information about power back-off; and demodulating the received downlink data on the basis of the configuration information about power back-off, wherein the configuration information about power back-off may comprise information related to at least one of the following: whether to apply power back-off, the reduced amount of power of downlink data by power back-off, a frame index to which power back-off is applied, a subframe index and a resource to which power back-off is applied.

Dependent claims

A method for transmitting a power headroom report (PHR), the method performed by a terminal and comprising:

receiving, by the terminal with dual connectivity to two cell groups, a configuration of a PHR mode;
generating, by the UE, the PHR based on the received configuration of the PHR mode;
and
transmitting the generated PHR to a serving cell belonging to one cell group among the two cell groups,
wherein the PHR mode indicates whether a mode for computing a power headroom for the other cell group is a real mode or a virtual mode, and
wherein if the mode for computing the power headroom is the virtual mode, the PHR is generated by computing the power headroom based on an assumption that at least one of PUSCH and PUCCH is not transmitted on any serving cell of the other cell group.
