摘要： A base station apparatus for communicating with a terminal apparatus receives direct link setup information, and in a case that Intra-BSS Spatial Reuse (SR) is enabled, the base station apparatus generates SR link information including a terminal apparatus to perform direct link and a color index associated with the terminal to perform direct link, and notifies the terminal apparatus of the SR link information. The terminal apparatus receives the SR link information, and acquires the terminal apparatus to perform direct link supporting intra-BSS SR and the color index corresponding to the terminal apparatus to perform direct link supporting intra-BSS SR. intra-BSS SR is performed for data used by an application for which traffic with high priority and/or with low latency is specified, and communication efficiency can be improved in coordination with the application.

摘要： The present disclosure includes a control unit that performs an uplink (UL) data transmission setting according to a radio resource control (RRC) message and a transmitting unit that transmits UL data according to the UL data transmission setting. The RRC message includes setting information of a plurality of configured UL grants (CGs). The setting information includes at least first and second CGs for each of at least one bandwidth part (BWP). The setting information further includes setting information related to transmission intervals for the first and second CGs. The control unit sets at least the first and second CGs for each BWP according to the setting information. The transmitting unit, when at least a part of the transmission interval of the first and second CGs overlap each other, interrupts UL data transmission of the first CG to perform UL data transmission of the second CG.

摘要： In a case that a base station apparatus or a terminal apparatus performs transmission by beamforming and further performs carrier aggregation, Quasi-colocation (QCL) is configured between component carriers. The configured QCL is used for calculating Channel State Information (CSI). Further, the CSI of a component carrier is calculated based on the configuration of QCL between the component carrier and an antenna port. Further, the CSI of the component carrier is calculated based on the number of antenna ports to be used.
