Abstract
There is provided a terminal device (2) which communicates with a base station apparatus (1). In a case where a PDCCH for a serving cell of frame structure type 2 is monitored in a serving cell of frame structure type 1, a TPC command included in the PDCCH is received based on a predetermined value.
Claims8
A terminal device comprising:
- a reception circuitry that receives a physical downlink control channel (PDCCH), and
- a transmission circuitry that sets transmitted power for transmission of a physical uplink shared channel (PUSCH) in a subframe i, in a certain serving cell,
- wherein
- the transmission circuitry sets the transmission power for the transmission of the PUSCH, by using a value which is obtained by a transmission power control (TPC) command included in a PDCCH which is received in a subframe (i-KPUSCH),
- a value of KPUSCH for a serving cell of frame structure type 1 is 4,
- the value of KPUSCH for a serving cell of frame structure type 2 is given in accordance with an uplink reference UL/DL configuration, and
- in a case where a PDCCH for the serving cell of the frame structure type 2 is monitored in the serving cell of the frame structure type 1, the uplink reference UL/DL configuration for the serving cell of the frame structure type 2 corresponds to a UL/DL configuration for the serving cell of the frame structure type 2.
