Patent ID: 11039406

Abstract:
There is provided a terminal apparatus configured to communicate with a base station apparatus. The terminal apparatus is configured to: receive information indicating a subframe of a first subframe set and a subframe of a second subframe set by using a higher layer signaling. The terminal apparatus is configured to, in a case that a power headroom for a predetermined subframe for a predetermined serving cell is calculated: calculate the power headroom based on a reference format by using a first set of parameters in a case that transmission in a physical uplink shared channel is not performed in the predetermined subframe for the predetermined serving cell, and the predetermined subframe belongs to the first subframe set; and calculate the power headroom based on the reference format by using a second set of parameters in a case that the transmission in the physical uplink shared channel is not performed in the predetermined subframe for the predetermined serving cell, and the predetermined subframe belongs to the second subframe set.
