Abstract

Embodiments of the disclosure provide a method and apparatus for transmitting and obtaining a power headroom report (PHR) in a Time Division Duplex (TDD) system, the TDD system being configured with a first uplink (UL) subframe set and a second UL subframe set. The method for transmitting comprises: in response to satisfying a trigger condition predetermined for both of the first and second UL subframe sets, determining a PHR for at least one of the first and second UL subframe sets; and transmitting to a base station an information block comprising the determined PHR, an implicit UL subframe set indication and/or an explicit UL subframe set indication indication indicating the determined PHR is for the first or second UL subframe set.
