Abstract: This application discloses that a terminal device determines at least one target time parameter set based on N time parameter sets, where time unit lengths corresponding to at least two of the N time parameter sets are different; determines M target times based on a first time and the at least one target time parameter set, generates a codebook based on response information corresponding to downlink information received at at least one of the M target times, and sends the codebook to a network device at the first time. Correspondingly, the network device determines, based on the response information included in the codebook, whether the downlink information corresponding to the response information is successfully transmitted. Therefore, when the time unit lengths corresponding to the at least two of the N time parameter sets are different, the network device and the terminal device have a consistent understanding of the codebook.

The method includes: A terminal device receives downlink control information DCI, where cyclic redundancy check CRC of the DCI is scrambled by using a first RNTI, the DCI is used to schedule a first downlink data channel, and the first downlink data channel is scrambled by using a second RNTI; and the terminal device receives the first downlink data channel based on the DCI. The DCI includes a DAI domain and/or an FDRA domain. The DAI domain indicates a count of first HARQ-ACK information in a first HARQ-ACK codebook, and the first HARQ-ACK codebook corresponds to the first RNTI. The FDRA domain indicates, within a frequency domain range of a public frequency resource, a scheduled frequency domain resource on the first downlink data channel.

Abstract: A resource determining method and an apparatus are disclosed. A network device determines a resource of an uplink channel. A terminal device receives downlink control information (DCI) sent by the network device, where the DCI is carried on a physical downlink control channel (PDCCH). The terminal device determines the resource of the uplink channel based on the DCI, where the resource of the uplink channel is used to send uplink information. As a result, a latency of sending the uplink information is reduced.

Abstract: In a signal transmission method and apparatus, a network device sends scheduling information of at least one of two carriers whose communication directions are opposite on a target OFDM symbol; a terminal device performs channel transmission of a target carrier on the target OFDM symbol based on the scheduling information, where the target carrier is one of carriers that are of the two carriers whose communication directions are opposite and that have channel transmission on the target OFDM symbol; and the network device performs channel transmission on the target OFDM symbol and the target carrier. A time domain resource may be allocated to a carrier on which transmission scheduling is currently performed, thereby improving transmission resource utilization and reducing a waiting delay.

Abstract: A first uplink channel is obtained to carry joint information of second uplink control information carried on a second channel and third uplink control information carried on a third uplink channel. In response to the first and third uplink channels meeting a first condition, the joint information is sent on the first uplink channel. Otherwise, the third uplink control information is sent on the third uplink channel. The first condition includes at least one of: (i) a distance between ending symbols on the first and third uplink channels is less than or equal to a first threshold, (ii) a distance between starting symbols on the first and third uplink channels is less than or equal to a second threshold, or (iii) a difference between coding rates of the first and third uplink channels is less than or equal to a third threshold.

Abstract: A communication method and a communications apparatus are provided. A principle of the method is as follows. Currently, for downlink data transmitted in a semi-persistent scheduling manner, only 1-bit acknowledgment information can be fed back in one time unit. However, as a transmission periodicity P of the downlink data transmitted in the semi-persistent scheduling manner becomes smaller, multi-bit acknowledgment information may need to be fed back in one time unit. In view of this, this application provides a communication method and a communications apparatus to feed back multi-bit acknowledgment information in one time unit. First, multi-bit acknowledgment information to-be-sent in one time unit is determined; then N acknowledgment codebooks are generated, where the N acknowledgment codebooks are used to carry the multi-bit acknowledgment information; and finally, the N acknowledgment codebooks are sent in the time unit.

Abstract: Embodiments of the present disclosure provide a data transmission method. The method includes: sending, by a network device, first indication information, where the first indication information includes N bits, the N bits are corresponding to M time units, the M time units are corresponding to at least one time length, a value of each bit is used to indicate whether a corresponding time unit is used to transmit data of a terminal device, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1; and sending, by the network device, downlink data in a time unit that is used to transmit the data of the terminal device, where the time unit is indicated by the N bits. Therefore, a unified time domain resource indication manner can be used in different scenarios to reduce complexity of a signaling design.
