Abstract
order to transmit and/or receive adequately data even when data scheduling methods that are different from those of existing LTE systems are applied, a terminal is proposed comprising: a receiving section configured to receive downlink control information for scheduling a downlink shared channel, the downlink control information including a first field that is associated with a first number of slots from an ending slot of downlink shared channel reception to a slot of Hybrid Automatic Repeat reQuest (HARQ)-Acknowledgement (ACK) information transmission for the downlink shared channel; the downlink control information including a second field that is associated with a second number of slots from a slot of downlink control information reception to a slot of the downlink shared channel reception; and a control section configured to determine the slot of the downlink shared channel reception based on the second number, wherein the receiving section is further configured to receive a higher layer signaling indicating a third number of consecutive slots for the downlink shared channel; the control section is further configured to determine the slot for the HARQ-ACK information transmission based on the first number, the second number, and the third number; one transport block is transmitted in the downlink shared channel in the consecutive slots; the one transport block is repeated in each of the consecutive slots; and different redundancy versions are applied to the consecutive slots.
Claims (7)
1. A terminal comprising: a receiving section configured to receive downlink control information for 5 scheduling a downlink shared channel, the downlink control information including a first field that is associated with a first number of slots from an ending slot of downlink shared channel reception to a slot of Hybrid Automatic Repeat reQuest (HARQ)-Acknowledgement (ACK) information transmission for the downlink shared channel, the downlink control information including a second field that is 10 associated with a second number of slots from a slot of downlink control information reception to a slot of the downlink shared channel reception; and a control section configured to determine the slot of the downlink shared channel reception based on the second number, wherein: 15 the receiving section is further configured to receive a higher layer signaling indicating a third number of consecutive slots for the downlink shared channel, the control section is further configured to determine the slot for the HARQ-ACK information transmission based on the first number, the second 20 number, and the third number, one transport block is transmitted in the downlink shared channel in the consecutive slots, the one transport block is repeated in each of the consecutive slots, and different redundancy versions are applied to the consecutive slots.
