摘要： A terminal device and a base station device efficiently communicate with each other. For the terminal device, in a case that third information is configured, a third maximum number of the layers assumed for determining a bit width for a first RI and a fourth maximum number of the layers assumed for determining a bit width for a second RI are provided, based on the third information. In case that the third information is not configured, the third maximum number and the fourth maximum number are provided, based on a smallest one of a first number and a second number. The first number is a second maximum number of the layers indicated by second information, and the second number is a largest one of the number of antenna ports of a first CSI-RS resource and the number of antenna ports of a second CSI-RS resource.

摘要： A terminal device and a base station device are capable of communicating with each other efficiently using an uplink channel. The terminal device transmits a transport block on a first shared channel upon detection of a control channel including first control information. For the first control information along with a CRC parity bit scrambled by a first identifier, a size of the transport block is given using a first information field included in the first control information along with the CRC parity bit scrambled by the first identifier, based on whether a second shared channel for an initial transmission of a transport block identical to the transport block corresponding to the first control information is scheduled by a random access response grant.

摘要： A terminal device including a reception unit configured to receive higher layer signalling including a first configuration relating to measurement of a Received Signal Strength Indicator (RSSI) and a second configuration relating to reporting of the RSSI, a measurement unit configured to measure the RSSI and/or a channel occupancy; and a transmission unit configured to report a measurement result for the RSSI and/or the channel occupancy. The measurement result for the RSSI is an average of measurement results obtained in a first period, and
the channel occupancy is obtained based on the measurement results equal to or greater than a first threshold among the measurement results obtained in the first period.-

摘要： There are provided a terminal device, a base station device, a communication method, an integrated circuit, and a wireless communication system that enable a base station device and a terminal device to determine parameters related to uplink signals or uplink reference signals and to perform efficient communication. In a terminal device that transmits a demodulation reference signal, a sequence group number is determined on the basis of a value of a parameter configured by a higher layer in a case where a transmission on a physical uplink shared channel is performed in accordance with a downlink control information format to which CRC parity bits scrambled by a C-RNTI are attached, which is transmitted on an enhanced physical downlink control channel, and the sequence group number is determined on the basis of a physical layer cell identity in a case where a transmission on the physical uplink shared channel is performed in accordance with a downlink control information format to which CRC parity bits scrambled by a Temporary C-RNTI are attached, which is transmitted on a physical downlink control channel.
