User equipments, base stations and methods
A user equipment (UE) is described. Receiving circuitry is configured to receive a radio resource control (RRC) message including information used for configuring more than one periodicities, each of the more than one periodicities corresponding to each of more than one uplink bandwidth parts (UL BWPs). The receiving circuitry is also configured to receive on a physical downlink control channel (PDCCH), a downlink control information format used for scheduling of a physical uplink shared channel (PUSCH), the downlink control information format being used for activating one UL BWP among the more than one UL BWPs. Transmitting circuitry is configured to perform, based on a periodicity among the more than one periodicities, an uplink transmission on the PUSCH in the activated one UL BWP. The periodicity among the more than one periodicities is determined based on the activated one UL BWP in which the uplink transmission is performed on the PUSCH.
1. A user equipment comprising:
receiving circuitry configured to:
receive a first radio resource control (RRC) message including first information used for configuring a plurality of periodicities, each of the plurality of periodicities corresponding to one of a plurality of subcarrier spacings for uplink bandwidth parts (UL BWPs);
receive a second RRC message including second information used for configuring the plurality of subcarrier spacings for the UL BWPs; and
receive, on a physical downlink control channel (PDCCH), a downlink control information format used for scheduling of a physical uplink shared channel (PUSCH), the downlink control information format being used for activating one UL BWP; and
transmitting circuitry configured to perform, based on a periodicity among the plurality of periodicities, an uplink transmission on the PUSCH in the activated one UL BWP, wherein
the periodicity among the plurality of periodicities is determined based on a subcarrier spacing configured for the activated one UL BWP in which the uplink transmission is performed on the PUSCH.
2. A base station apparatus comprising:
transmitting circuitry configured to:

transmit a second RRC message including second information used for configuring the plurality of subcarrier spacings for the UL BWPs; and
transmit, on a physical downlink control channel (PDCCH), a downlink control information format used for scheduling of a physical uplink shared channel (PUSCH), the downlink control information format being used for activating one UL BWP; and
receiving circuitry configured to receive, based on a periodicity among the plurality of periodicities, an uplink transmission on the PUSCH in the activated one UL BWP, wherein
the periodicity among the plurality of periodicities is determined based on a subcarrier spacing configured for the activated one UL BWP in which the uplink transmission is performed on the PUSCH.

receiving a second RRC message including second information used for configuring the plurality of subcarrier spacings for the UL BWPs;
receiving, on a physical downlink control channel (PDCCH), a downlink control information format used for scheduling of a physical uplink shared channel (PUSCH), the downlink control information format being used for activating one UL BWP; and
performing, based on a periodicity among the plurality of periodicities, an uplink transmission on the PUSCH in the activated one UL BWP, wherein
the periodicity among the plurality of periodicities is determined based on a subcarrier spacing configured for the activated one UL BWP in which the uplink transmission is performed on the PUSCH.
