Abstract
Official abstract text for this publication.
An aspect of a terminal of the present disclosure includes: a reception section that receives information regarding one or more repetition factor candidates that are configured corresponding to a time domain resource allocated to a physical shared channel; and a control section that selects a specific repetition factor candidate based on a codepoint of a given field included in downlink control information used for scheduling the physical shared channel.
First claim
Opening claim text (preview).
1 .- 6 . (canceled) 7 . A terminal comprising: a receiver that receives at least one of first downlink control information scheduling a first uplink shared channel and second downlink control information used for activation of a second uplink shared channel transmission; and a processor that determines, based on repetition number candidates configured by a first higher layer parameter for an uplink shared channel configuration, a number of repetitions of the first uplink shared channel and a number of repetitions of the second uplink shared channel. 8 . The terminal according to claim 7 , wherein the processor controls a repetition of the second uplink shared channel transmission, based on the first higher layer parameter, the second downlink control information and a second higher layer parameter. 9 . The terminal according to claim 7 , wherein the repetition number candidates are commonly configured for the first uplink shared channel and the second uplink shared channel. 10 . A radio communication method for a terminal, comprising: receiving at least one of first downlink control information scheduling a first uplink shared channel and second downlink control information used for activation of a second uplink shared channel transmission; and determining, based on repetition number candidates configured by a first higher layer parameter for an uplink shared channel configuration, a number of repetitions of the first uplink shared channel and a number of repetitions of the second uplink shared channel. 11 . A base station comprising: a transmitter that transmits at least one of first downlink control information scheduling a first uplink shared channel and second downlink control information used for activation of a second uplink shared channel transmission; and a processor that controls, based on repetition number candidates configured by a first higher layer parameter for an uplink shared channel configuration, a number of repetitions of the first uplink shared channel and a number of repetitions of the second uplink shared channel. 12 . A system comprising a terminal and a base station, wherein the terminal comprises: a receiver that receives at least one of first downlink control information scheduling a first uplink shared channel and second downlink control information used for activation of a second uplink shared channel transmission; and a processor of the terminal that determines, based on repetition number candidates configured by a first higher layer parameter for an uplink shared channel configuration, a number of repetitions of the first uplink shared channel and a number of repetitions of the second uplink shared channel, and the base station comprises: a transmitter that transmits at least one of the first downlink control information and the second downlink control information; and a processor of the base station that controls, based on the repetition number candidates, the number of repetitions of the first uplink shared channel and the number of repetitions of the second uplink shared channel. 13 . The terminal according to claim 8 , wherein the repetition number candidates are commonly configured for the first uplink shared channel and the second uplink shared channel.
