Abstract: Embodiments of this application provide a control information sending method and apparatus. A network device generates first control information for a first TB, where the first TB includes n code block (CB) groups, where N is a maximum quantity of CB groups included in the first TB; each CB group includes at least one CB; the first control information includes N control information fields, and the N control information fields are in correspondence with the maximum N CB groups included in the first TB; and a control information field i in the N control information fields is used to indicate whether a CB group corresponding to the control information field i is to be sent or received, and i∈[1, N]. In this way, a quantity of bits included in downlink control information can remain fixed, thereby reducing blind detection complexity of a terminal device.

Abstract: In a data sending method, a terminal device receives first control information in a first time unit. The first control information indicates a first time domain resource that is used to send a first information block. The terminal device receives the first information block on at least a part of the first time domain resource based on the first control information. The terminal device further receives second control information in a second time unit. The second control information indicates a second time domain resource that is used to send the first information block. The terminal device receives the first information block on the second time domain resource based on the second control information. The first time unit is different from the second time unit, and the first time domain resource and the second time domain resource have an overlapping time domain resource.

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 provides a communication method and apparatus. A terminal receives from a network device, first indication information indicating N sets of information of feedback time, each of the N sets comprises at least one piece of information of feedback time, each of the at least one piece of information of feedback time indicates a quantity of time units comprised in a feedback time of a data block. The terminal receives downlink control information (DCI) from the network device, wherein the DCI comprises second indication information indicating first information of feedback time of the data block, and the first information of feedback time belongs to a first set of information of feedback time, and the first set is one of the N sets.
