Abstract: A method and an apparatus for sending hybrid automatic repeat request acknowledgement/negative acknowledgement information are disclosed, and relate to the communications field, to specify a mechanism for feeding back information indicating whether a decoding result of downlink data repeatedly transmitted in a slot is correct. The method includes: determining a first downlink data occasion set based on a time domain resource indicated by a time domain resource allocation (TDRA) table; determining a first downlink data occasion based on a start time domain resource for sending downlink data; adding feedback information (for example, information indicating whether a decoding result of the downlink data is correct) to a feedback location corresponding to the first downlink data occasion; determining a feedback slot based on a slot to which the start time domain resource for sending the downlink data belongs and a first offset K1; and feeding back a HARQ-ACK codebook in the feedback slot.

Abstract: This application discloses a communication method, apparatus, and system. A network device sends a first downlink common signal (for example, an SSB) to a terminal device. The terminal device receives system information from the network device based on the SSB. The system information carries information indicating a first frequency domain resource and a second frequency domain resource. The first frequency domain resource and the second frequency domain resource may be two carriers or two BWPs, and the two frequency domain resources correspond to different uplink-downlink configurations. The terminal device selects a first random access resource from a random access resource set based on an association relationship between an SSB and a random access resource to send a random access preamble. The random access resource set includes a random access resource on the first frequency domain resource and a random access resource on the second frequency domain resource.
