no. 1 Embodiment approach

[0039] Hereinafter, a first embodiment of the present invention will be described. The description will be given using a communication system (cellular system) in which a base station device (base station, Node B, eNB (eNodeB)) and a terminal device (terminal, mobile station, user device, UE (User equipment)) communicate in a cell.

[0040] Main physical channels and physical signals used in EUTRA and Advanced EUTRA are explained. The so-called channel refers to a medium used for signal transmission, and the so-called physical channel refers to a physical medium used for signal transmission. In this embodiment, a physical channel can be used synonymously with a signal. In EUTRA and AdvancedEUTRA, physical channels may be added in the future, or their structures and formats may be changed or added, but even if they are changed or added, they will not affect the description of this embodiment.

[0041] In EUTRA and Advanced EUTRA, radio frames are used to manage the scheduling...

Abstract

In the present invention, when dual connectivity is set, a first cell group includes a primary cell, and a physical uplink channel in a second cell group is a physical uplink control channel in the second cell group, power for the physical uplink channel in the second cell group is determined on the basis of whether PSCG, which is maximum transmission power for the second cell group, is exceeded, wherein PSCG is calculated through computation using at least PCMAX, PMeNB, and power for a physical uplink control channel in the first cell group.

Description

technical field [0001] Embodiments of the present invention relate to a technique of a terminal device, a base station device, and a communication method that realize efficient sharing of channel state information. [0002] this application claims priority based on JP Japanese Patent Application No. 2014-147311 for which it applied to Japan on July 18, 2014, and uses the content here. Background technique [0003] In the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), which is a standardization plan, a predetermined frequency / The adoption of flexible scheduling in units of time has led to standardization of Evolved Universal Terrestrial Radio Access (Evolved Universal Terrestrial Radio Access (hereinafter referred to as EUTRA), which realizes high-speed communication. [0004] In addition, 3GPP is conducting research on Advanced EUTRA, which realizes higher-speed data transmission and has higher compatibility with EUTRA. EUTRA is a communica...
