Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device determines a target cell from a set of cells, the set of cells being configured for uplink control transmissions for HARQ feedbacks for downlink data transmissions received on cells in a cell group, and transmits, on the target cell and to a network device, an uplink control transmission for a HARQ feedback for a downlink data transmission received on one of the cells in the cell group. In this way, a latency for HARQ feedback can be reduced.

Abstract: According to embodiments of the present disclosure, a solution for supporting repetitions for a plurality of downlink data transmission scheduled by signal downlink control information is proposed. A terminal device receives downlink control information scheduling a plurality of downlink data transmissions with repetitions from a network device. The terminal device determines a HARQ-ACK codebook for the plurality of downlink data transmissions based on a repetition pattern for the plurality of downlink data transmissions and the slot offset. The terminal device transmits a feedback for the repetitions for the downlink data transmissions based on the HARQ-ACK codebook to the network device. In this way, it achieves a flexible repetition patterns for the plurality of downlink data transmissions scheduled by signal DCI, which improves the coverage/reliability performance for data transmission.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A network device generates downlink control information scheduling multiple data channels grouped into a plurality of groups, and transmits the downlink control information to a terminal device. Upon receipt of the downlink control information, the terminal device performs data transmission between the terminal device and the network device based on the grouped data channels. In this way, a payload of the downlink control information can be reduced and false detection rate can also be reduced.

Abstract: Embodiments of the present disclosure provide a solution for transmitting HARQ feedback. A method for communications comprises in accordance with a determination that a first resource for transmission of a first HARQ feedback for a first SPS downlink transmission is unavailable, determining, at a terminal device, a second resource subsequent to the first resource in time domain. The method further comprises transmitting to a network device the first HARQ feedback on the second resource.

Abstract: 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.

Abstract: Embodiments of the disclosure generally relate to feedback of a HARQ acknowledgement. A network device transmits, to a terminal device, a first trigger indicating a feedback mode of a HARQ acknowledgement. The feedback mode is selected from at least one of: a trigger mode, a timing mode, and a mixed mode. In response to successful access to an unsilenced band allocated to the HARQ acknowledgement, the network device transmits, to the terminal device, a second trigger indicating at least one target terminal device that is to feedback the HARQ acknowledgement based on the feedback mode indicated by the first trigger.
