Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.

A terminal transmits an uplink control channel corresponding to an antenna beam transmitted from a radio base station. The terminal assumes a symbol location of a repetition of the uplink control channel based on an explicit or implicit notification.

Sidelink downlink control information (SL DCI) associated with transmission of one or more sidelink signals may be communicated. A wireless user device may transmit, based on the SL DCI and to one or more second wireless user devices, the one or more sidelink signals via a first quantity of sidelink channel resources. The wireless user device may receive first sidelink HARQ feedback information responsive to the one or more sidelink signals. The wireless user device may determine, based on a sidelink HARQ feedback timing, a time interval to transmit the first sidelink HARQ feedback information. The wireless user device may determine, based on the first quantity, a sidelink HARQ codebook. The wireless user device may transmit, during the time interval, based on the sidelink HARQ codebook, and to the base station, an uplink signal indicating the first sidelink HARQ feedback information.

Embodiments of the present disclosure relate to devices, methods and computer readable storage media of HARQ feedback for multiple data channels scheduled by a single DCI. The method comprises receiving, at a terminal device, control information from a network device; in accordance with a determination that transmissions of a plurality of transport blocks from the network device to the terminal device on a set of data channels are scheduled by the control information, determining a control channel for transmitting Hybrid Automatic Repeat Request, HARQ, feedback information associated with the plurality of transport blocks; and transmitting the HARQ feedback information via the control channel to the network device. In this way, the enhancement on HARQ-ACK feedback mechanism for terminal device in a case when multiple TBs/independent PDSCHs are scheduled by a single DCI can be reached, which may alleviate possible PUCCH collisions and provide more flexibility.

An apparatus and a method for a hybrid automatic repeat request (HARQ) feedback transmission are provided. A method for a HARQ feedback transmission includes receiving a multicast broadcast service (MBS) transport block (TB) from a base station, decoding the MBS TB, and transmitting, to the base station, a HARQ feedback in a form of a negative acknowledgement (NACK)-only report when the UE incorrectly decodes the MBS TB.

To appropriately perform communication even in a case where a transmission timing/transmission period for retransmission control information is flexibly controlled (is variable), an aspect of a user terminal according to the present invention includes a transmitting section that transmits retransmission control information for DL transmission and a control section that controls transmission of the retransmission control information at certain timings reported from a base station. A time window is configured for the retransmission control information, the control section controls transmission of the retransmission control information, based on the certain timings and the time window configured for the retransmission control information, and at least one of the certain timings is included within a range of the time window.

A user equipment includes a receiving unit configured to receive a first signal of inter-terminal direct communication transmitted from a first user equipment, and information indicating a first resource for transmitting a HARQ (Hybrid Automatic Repeat Request) response corresponding to the first signal of inter-terminal direct communication transmitted from either one of a base station apparatus or the first user equipment; a control unit configured to determine the HARQ response based on a reception result of the first signal of inter-terminal direct communication; and a transmitting snit configured to transmit the determined HARQ response to the base station apparatus or the first user equipment, by using the first resource for transmitting the HARQ response.

A method for performing a hybrid automatic repeat request (HARQ) transmission and a user equipment (UE) are provided. The method at the UE comprises the followings. Receiving a first configuration related to slot aggregation for physical downlink shared channel (PDSCH) reception. Receiving a downlink control information (DCI). Receiving a PDSCH indicted by the DCI across a first number of aggregated slots. Transmitting a codebook comprising a first information and a second information.

The present application provides a method and device in a node for wireless communications. A first node receives a second signaling, transmits a second bit set in a second time-frequency resource block. The second signaling indicates the second time-frequency resource block; the second signaling is used to determine a first time-frequency resource block, and the first time-frequency resource block is reserved for a first bit set; whether the second bit set comprises the first bit set is at least related to the second signaling is a first-type signaling or a second-type signaling; when the second signaling is the second-type signaling, the second bit set comprises the first bit set; when the second signaling is the first-type signaling, whether the second bit set comprises the first bit set is related to whether there exists a bit block in the first bit set comprising a HARQ-ACK associated with the second-type signaling.

A terminal and a method performed by the same in a wireless communication system are provided for improved communication efficiency. The method includes receiving at least one PDSCH from one or more scheduled PDSCHs. Each of the one or more PDSCHs includes a unicast PDSCH including a dynamically scheduled unicast PDSCH and/or a unicast semi-persistent scheduling PDSCH, and/or a multicast PDSCH including a dynamically scheduled multicast PDSCH and/or a multicast SPS PDSCH, and feeding back hybrid automatic repeat request-acknowledgement information for the at least one received PDSCH.
