A wireless device may receive an indication that repetition of downlink control information (DCI) is scheduled via a first monitoring occasion and a second monitoring occasion. The wireless device may transmit one or more feedback information bits via an uplink resource. The one or more feedback information bits may be based on a downlink assignment index (DAI) corresponding to the earlier of the first monitoring occasion and the second monitoring occasion.

A terminal according to an aspect of the present disclosure includes: a reception section that receives downlink control information for triggering feedback of a one-shot HARQ-ACK; and a control section that controls feedback of HARQ-ACKs each corresponding to one of a plurality of service types or HARQ-ACKs having different priorities by using different codebooks in a case where the feedback of the HARQ-ACK is performed on the basis of the downlink information.

Disclosure provides a method and device in a node for wireless communications. A first receiver, receives a first signaling; and a first transmitter, transmits a first signal in a target time-frequency-resource block, and the first signal carries a second bit block; herein, the first signaling is used to determine a first bit block; the first bit block comprises a second-type HARQ-ACK; the first bit block is used to generate the second bit block; the first time-frequency-resource block and the second time-frequency-resource block are respectively reserved for different bit blocks; a number of resources used to transmit a first-type HARQ-ACK in the first time-frequency-resource block is used to determine whether the target time-frequency-resource block is the first time-frequency-resource block or the second time-frequency-resource block; the first-type HARQ-ACK corresponds to a first index; the second-type HARQ-ACK corresponds to a second index; the first signaling indicates the second index.

An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, including signaling a maximum physical sidelink feedback channel (PSFCH) receiving capability to a base station; and receiving a wireless signal transmitted from the base station based on the maximum PSFCH receiving capability, wherein the maximum PSFCH receiving capability is a maximum number of PSFCHs receivable during one time transmission interval (TTI).

Disclosure discloses a method and a device in a node for wireless communications. A first node receives first information; and transmits a first signaling in a first sub-channel; the first information indicates a first resource pool; the first sub-channel is one of L sub-channels, and frequency-domain resource blocks comprised by any one of the L sub-channels belong to the first resource pool; a first candidate sub-channel and a second candidate sub-channel are two different sub-channels among the L sub-channels, a frequency-domain resource block comprised by the first candidate sub-channel and a frequency-domain resource block comprised by the second candidate sub-channel are the same; either of the first candidate sub-channel and the second candidate sub-channel belongs to a target sub-channel group, the target sub-channel group comprising at least one sub-channel. The present disclosure makes full use of all resources available in the sidelink resource pool.

A terminal includes: a receiving unit receiving single control information for scheduling a plurality of cells; and a control unit receiving a transport block from the plurality of cells, based on the control information, in which the control unit: receives different transport blocks in each of the plurality of cells; receives a same transport block in each of the plurality of cells; or receives a part of a transport block in each of the plurality of cells.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may reserve a transmission resource for transmitting a transmission block (TB) via a sidelink communication; reserve a retransmission mission resource for retransmitting the TB, wherein the retransmission resource is reserved such that at least one hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback occasion occurs between transmission of the TB and a first retransmission of the TB; and communicate with another UE via the sidelink communication based at least in part on the transmission and retransmission resources. Numerous other aspects are provided.

This application discloses an information feedback method, a resource scheduling method, a terminal, and a network device. The information feedback method includes: performing HARQ-ACK feedback for multicast downlink transmission and unicast downlink transmission in one time unit.

A method for transmitting automatic repeat request acknowledgement feedback information supporting a multicast service and an apparatus are provided. The method includes: receiving N pieces of first downlink control information (DCI) and M pieces of second DCI in at least one first time unit, where the first DCI is a first-type DCI, the second DCI is a second-type DCI. Each piece of first DCI includes a first downlink assignment index (DAI), and the first DAI includes a first counter downlink assignment index (C-DAI) that indicates an accumulative quantity of pieces of first-type DCI for scheduling transmission of a downlink data channel. Each piece of second DCI includes a second DAI, and the second DAI includes a second C-DAI that indicates an accumulative quantity of pieces of second-type DCI for scheduling transmission of a downlink data channel.

A terminal according to one embodiment of the present invention may: receive first DCI including a first HARQ process ID field and a first NDI field on the basis of a first RNTI for a terminal group; receive a first PDSCH scheduled by the first DCI; receive second DCI on the basis of a second RNTI dedicated to the terminal in a state in which a data block of the first PDSCH has not been successfully decoded; and receive a second PDSCH scheduled by the second DCI, wherein a second HARQ process ID field included in the second DCI indicates the same HARQ process as the first HARQ process ID field included in the first DCI; and, on the basis of the fact that a value of a second NDI field included in the second DCI is the same as the value of the first NDI field included in the first DCI, a data block of the second PDSCH may be decoded on the assumption that the second PDSCH includes retransmission for the data block of the first PDSCH that has not been successfully decoded, notwithstanding that the second RNTI is different from the first RNTI.
