Abstract
A terminal according to one aspect of the present disclosure includes a control section that determines mapping of a sequence of a redundancy version (RV) which is to be applied for a channel that is repeatedly transmitted, to each transmission occasion, based on a field of downlink control information (DCI) for scheduling the channel, and a receiving section that receives the channel based on the mapping. According to one aspect of the present disclosure, repetition processing can be appropriately controlled.
Claims4
A terminal comprising:
- a processor that determines, based on a field regarding redundancy version (RV) and a transmission configuration indication (TCI) field indicating a number of TCI in downlink control information (DCI) scheduling a channel repetitively transmitted, a mapping between a plurality of indices of the RV applied for the channel and each transmission occasion of the channel;
- and
- a receiver that receives the channel based on the mapping,
- wherein the processor determines the mapping based on a codepoint of the TCI field, in response to an offset between a reception of the DCI and a reception of the channel being less than a threshold.
A radio communication method for a terminal, comprising:
- determining, based on a field regarding redundancy version (RV) and a transmission configuration indication (TCI) field indicating a number of TCI in downlink control information (DCI) scheduling a channel repetitively transmitted, a mapping between a plurality of indices of the RV applied for the channel and each transmission occasion of the channel;
- and
- receiving the channel based on the mapping,
- wherein the mapping is determined based on a codepoint of the TCI field, in response to an offset between a reception of the DCI and a reception of the channel being less than a threshold.
A base station comprising:
- a processor that controls generation of downlink control information (DCI) that schedules a channel repetitively transmitted and contains a field regarding redundancy version (RV) and a transmission configuration indication (TCI) field indicating a number of TCI for determining a mapping between a plurality of indices of the RV applied for the channel and each transmission occasion of the channel, wherein the mapping is determined based on a codepoint of the TCI field, in response to an offset between a reception of the DCI and a reception of the channel being less than a threshold;
- and
- a transmitter that transmits the DCI and transmits the channel.
A system comprising a terminal and a base station, wherein
- the terminal comprises:
- a processor of the terminal that determines, based on a field regarding redundancy version (RV) and a transmission configuration indication (TCI) field indicating a number of TCI in downlink control information (DCI) scheduling a channel repetitively transmitted, a mapping between a plurality of indices of the RV applied for the channel and each transmission occasion of the channel;
- and
- a receiver that receives the channel based on the mapping,
- wherein the processor determines the mapping based on a codepoint of the TCI field, in response to an offset between a reception of the DCI and a reception of the channel being less than a threshold, and
- the base station comprises:
- a processor of the base station that controls generation of the DCI, and
- a transmitter that transmits the DCI and transmits the channel.
