no. 1 approach

[0055] figure 1 It is an explanatory diagram showing an example of the wireless communication system 1 of the first embodiment. figure 1 The illustrated wireless communication system 1 includes a base station 2 and a terminal device 3 . For example, the base station 2 transmits and receives data (such as eMBB data and URLLC data) to and from the terminal device 3 through a wireless carrier. For example, the base station 2 is a gNB such as an NR cell. For example, the terminal device 3 transmits and receives data (eg, eMBB data and URLLC data) to and from the base station 2 through the wireless carrier.

[0056] figure 2 is a block diagram showing an example of the base station 2 of the first embodiment. figure 2 The illustrated base station 2 includes an antenna 11 , a transmitting part 12 , a receiving part 13 , a first memory 14 and a first processor 15 . For example, the antenna 11 transmits and receives wireless signals of a wireless carrier. The transmitter 12 is ...

[0092] Image 6 It is an explanatory diagram showing an example of the wireless communication system 1A of the second embodiment. The same components as those of the wireless communication system 1 of the first embodiment are denoted by the same reference numerals, and descriptions of the same configurations and operations will be omitted. Image 6 The illustrated wireless communication system 1A includes a first base station 2A and a terminal device 3 . For example, the first base station 2A has a figure 2 The base station 2 is shown with the same configuration. The terminal device 3 performs simultaneous communication with the first base station 2A using two carriers.

[0093] Figure 7 It is a block diagram showing an example of the power information generation unit 23 of the second embodiment. Figure 7 The illustrated power information generation section 23 includes a fourth collection section 42D in place of the third collection section 42C, and includes a fourth g...

[0108] Figure 9 It is a block diagram showing an example of the power information generation unit 23 of the third embodiment. When the first base station 2A is a base station of an LTE cell, the first correction amount and the second correction amount are not required. exist Figure 9 In the illustrated power information generation unit 23, since the first correction amount and the second correction amount are unnecessary, the first collection unit 42A, the second collection unit 42B, the first generation unit 44A, and the second generation unit 44B are deleted. Further, the power information generation unit 23 causes the generation unit 43 to generate the parameters, and causes the fourth generation unit 44D to generate the fourth correction amount.

Abstract

The terminal device (3) includes a processor circuit (55) and a receiver (53). The processor circuit is configured to perform dual connectivity with the cell group and the different cell groups. The processor circuit is configured to control transmission power sharing between the group of cells and the different groups of cells. The processor is configured to transmit power amounts of the cell group and the different cell groups when the transmissions of the cell group overlap in time with the transmissions of the different cell groups and during the overlapping time When the total amount is greater than the configured maximum transmission power amount, reduce the transmission power amount of the cell group or the transmission power amount of the different cell groups during the overlap time, so that the transmission power amount of the cell group and the The total amount of transmission power of the different cell groups is less than or equal to the configured maximum amount of transmission power. A receiver is configured to receive signals on the group of cells and the group of different cells.

Description

technical field [0001] The present invention relates to a terminal device, a base station device, a wireless communication system and a wireless communication method. Background technique [0002] In current networks, services of terminal devices such as mobile terminals (smartphones and feature phones) occupy most of the network resources. In addition, the services used by mobile terminals tend to increase. [0003] Furthermore, with the development of Internet of Things (IoT) services such as transportation systems, smart meters, and monitoring systems for equipment and the like, services with various requirements need to be addressed. Therefore, in the communication standard of the next generation (for example, the fifth generation mobile communication (5G)), in addition to the standard technology of the fourth generation mobile communication (4G), it is expected to achieve higher data rate, larger capacity, and lower technology of time delay (for example, see Non-Paten...
