Abstract
Embodiments of the present disclosure relate to method, device and computer readable medium for hybrid automatic repeat request (HARQ) feedback. The method comprises receiving, from a network device, first control information at least comprising first channel indices for a first group of data channels and second channel indices for a second group of data channels, the first group of the data channels being at least part of a first set of data channels scheduled for data transmission from the network device to the terminal device and the second group of the data channels being at least part of a second set of data channels scheduled for the data transmission. The method also comprises generating, based on the first control information, feedback information indicating first reception states of data on the first group of data channels in association with the first channel indices and second reception states of data on the second group of data channels in association with the second channel indices. The method further comprises transmitting the feedback information via an uplink channel to the network device. In this way, for the case that the HARQ ACK/NACK feedback related to multiple PDSCH groups in a same PUCCH, the miss detection of DCI in multiple PDSCH groups may reflect in the bit sequence for the HARQ ACK/NACK feedback, so that the network device may be aware of the miss detection and determine the data to be retransmitted.
