Abstract: A communication apparatus includes: a transmitter configured to perform physical uplink control channel (PUCCH) transmission; a receiver configured to receive, from a base station, configuration information including a synchronization signal/physical broadcast channel block (SSB) index indicating an SSB to be referred to for the PUCCH transmission; and a controller configured to control the PUCCH transmission with reference to the SSB indicated by the SSB index. The controller is configured to specify the SSB indicated by the SSB index as a non-cell-defining SSB in a case where an absolute radio-frequency channel number indicating a frequency location at which the non-cell-defining SSB is transmitted is received.

Abstract: A terminal includes a receiving unit which receives a system information block 1 (SIB1); and a control unit which determines: whether or not first information indicating that a Reduced Capability (RedCap) terminal is allowed to camp on a cell is included in the SIB1, and whether or not second information indicating that whether or not the cell is barred for a RedCap terminal with a specific number of receivers is included in the SIB1 in a case where the first information is included in the SIB1, wherein the control unit determines whether or not the cell is barred for the RedCap terminal with the specific number of receivers based on the second information.

Abstract: A terminal apparatus is configured to start a cycle of Discontinuous Reception (DRX), in which an on-duration timer for a DRX group is started based on a first mathematical expression in a case where the terminal apparatus receives information for indicating that a length of the DRX cycle is not an integer, and the on-duration timer is started based on a second mathematical expression in a case where the terminal apparatus does not receive the information for indicating that the length of the DRX cycle is not the integer.

Abstract: A communication apparatus comprises: a receiver configured to receive a system information block (SIB) from a base station; and a controller configured to determine a number of bits of a bitmap for an availability indication of a tracking reference signal (TRS) in downlink control information (DCI). The controller is configured to determine, in a case where a TRS resource set configuration that is a list of TRS resource sets is included in the SIB, the number of bits on a basis of an identifier related to the TRS resource set, and determine, in a case where the TRS resource set configuration is not included in the SIB, the number of bits as 0.
