Terminal device, base station apparatus, and method
There is provided a terminal device that communicates with a base station apparatus. The terminal device includes a transmission unit that configures a transmit power for transmission of a physical uplink shared channel in a serving cell belonging to a first cell group based on whether or not a physical random access channel is transmitted in the first cell group and a second cell group in a case where the first cell group and the second cell group are configured.
1. A terminal device comprising:
a higher layer processor configured to configure a first configuration for a first cell group and a second configuration for a second cell group;
a transmitter configured to transmit a physical uplink shared channel in a first subframe of the first cell group and transmit a physical random access channel in a second subframe of the second cell group, wherein
the transmitter is configured to set a transmit power of the physical uplink shared channel based on a transmit power of the physical random access channel in a case that the first subframe overlaps with the second subframe and the first subframe and the second subframe are synchronized.
2. The terminal device according to claim 1 , wherein
the transmitter is configured to set a transmit power of a physical uplink control channel of the first subframe based on the transmit power of the physical random access channel.
3. The terminal device according to claim 2 , wherein
the transmitter is configured to set a transmit power of a sounding reference signal of the first subframe based on the transmit power of the physical random access channel.
4. The terminal device according to claim 1 , wherein
for each of the first cell group and the second cell group, a third configuration related to a medium access control layer is configured.
5. The terminal device according to claim 4 , wherein
in a case that the third configuration for the first cell group includes a fourth configuration related to a discontinuous reception (DRX), the higher layer processor is configured to perform a DRX operation for the first cell group, and
in a case that the third configuration for the second cell group includes the fourth configuration, the higher layer processor is configured to perform a DRX operation for the second cell group.
