The UE includes receiving circuitry configured to receive a radio resource control message including first information used for indicating a periodicity. The receiving circuitry is also configured to receive on a physical downlink control channel (PDCCH), downlink control information (DCI) with CRC scrambled by a first Radio Network Temporary Identifier (RNTI), the DCI including information indicating a time domain resource. The UE also includes transmitting circuitry config- ured to perform, based on the DCI with CRC scrambled by the first RNTI, a transmission on a physical uplink shared channel (PUSCH) in a symbol. The time domain resource includes an index of the symbol in which the transmission on the PUSCH is performed and a slot offset value. The index of the symbol in which the transmission on the PUSCH is performed is within a slot given by the first information and the slot offset value.
