User equipment and base stations that achieve ultra reliable and low latency communications

A base station, comprising:

• transmitting circuitry configured to transmit a radio resource control (RRC) message comprising first information used for a physical uplink shared channel (PUSCH) transmission corresponding to a configured grant, the first information comprising a first parameter(s) and a second parameter(s), the first parameter(s) being for power control, the second parameter(s) being for configuring a type of frequency resource allocation,
• the transmitting circuitry configured to transmit an RRC message comprising second information used for a PUSCH transmission scheduled by a physical downlink control channel (PDCCH) with cyclic redundancy check (CRC) scrambled by a cell-radio network temporary identifier (C-RNTI), the second information comprising a third parameter(s) for configuring a type of frequency resource allocation,
• the transmitting circuitry configured to transmit a PDCCH with CRC scrambled by a configured scheduling radio network temporary identifier (CS-RNTI), the PDCCH being used for scheduling of a PUSCH retransmission corresponding to the configured grant, and reception circuitry configured to receive a PUSCH initial transmission corresponding to the configured grant by using the first parameter(s) and the second parameter(s),
• the reception circuitry configured to receive the PUSCH retransmission which is scheduled by the PDCCH and corresponds to the configured grant by using the first parameter(s) and the third parameter(s).

A method by a user equipment, comprising:

• receiving an RRC message comprising second information used for a PUSCH transmission scheduled by a physical downlink control channel (PDCCH) with cyclic redundancy check (CRC) scrambled by a cell-radio network temporary identifier (C-RNTI), the second information comprising a third parameter(s) for configuring a type of frequency resource allocation,
• monitoring a PDCCH with CRC scrambled by a configured scheduling radio network temporary identifier (CS-RNTI), the PDCCH being used for scheduling of a PUSCH retransmission corresponding to the configured grant,
• performing a PUSCH initial transmission corresponding to the configured grant by using the first parameter(s) and the second parameter(s), and
• performing, based on detection of the PDCCH, the PUSCH retransmission corresponding to the configured grant by using the first parameter(s) and the third parameter(s).
