[Object] To enable providing a wireless access technology in a more preferred aspect irrespective of a difference in design in accordance with a use case in a communication system in which the base station device communicates with the terminal device.

[Solution] A terminal device includes: a communication unit configured to perform wireless communication; and a control unit configured to perform control such that control information regarding a supported communication scheme is transmitted to an external device through the wireless communication. In a case in which a first communication scheme and a second communication scheme different from the first communication scheme are supported, the control unit associates, with the control information, a parameter indicating whether or not dual connectivity based on the first communication scheme and the second communication scheme is supported.

Apparatuses, systems, and methods for PUCCH reporting of reciprocity-based type-II codebook are disclosed. One apparatus (1100) includes a transceiver (1125) that receives, from a network entity, a channel state information (CSI) reporting configuration comprising a codebook type associated with a precoding matrix and CSI reference signals over a set of CSI reference signal (CSI-RS) resources based on the CSI reporting configuration. The apparatus (1100) includes a processor (1105) that identifies a set of co-efficients associated with the codebook based on the received set of CSI-RS resources. The transceiver (1125) transmits a CSI report on a physical uplink control(PUCCH) or a physical uplink shared channel (PUSCH) and based on the codebook type, the CSI report comprising CSI and the set of coefficients, wherein to transmit the CSI report on the PUCCH is based on a value of a sub-configuration or the CSI reporting configuration.
