Abstract: A communication method and a communication apparatus are described. A network device explicitly indicates, by using indication information, a transmission priority of data that can be carried on a scheduled transmission resource. After receiving the indication information, a terminal device can determine whether data currently to be sent can be sent on the scheduled transmission resource, to reduce a probability of a communication failure caused by resource preemption in a scenario in which data of at least three transmission priorities coexists. The terminal device may further determine, based on the indication information, whether to-be-received data exists on the scheduled transmission resource.

Abstract: This application provides a reference signal transmission method, a terminal device, and an access network device. By receiving first indication information from the access network device, the terminal device can determine, based on the first indication information, whether N1 resource blocks that are in a rate matching pattern group and that have an intersection with a time-frequency resource for transmitting a downlink data channel can be used to transmit the downlink data channel, and further determine a position of a reference signal of downlink data channel, to implement reference signal transmission.

Abstract: Example resource determining methods, indication methods, and apparatus are described. On example method includes receiving a downlink data channel by a terminal from a network device. The terminal determines a first uplink control channel resource from a plurality of uplink control channel resources based on an index of the last symbol for the downlink data channel and a time for processing the downlink data channel by the terminal. The terminal sends acknowledgment information to the network device on the first uplink control channel resource, where the acknowledgment information is used to determine a reception status of the downlink data channel.

Abstract: This application discloses a control information sending method, a data block transmission method, and a related apparatus. The control information sending method in this application is used to schedule multiple transmission time intervals TTIs for data transmission, and the multiple TTIs include at least a first TTI and a second TTI. The method includes: generating first control information, where the first control information is partial control information required for scheduling each of the multiple TTIs; generating second control information, where the second control information is remaining control information, other than the first control information, in complete control information for scheduling the first TTI; and generating third control information, where the third control information is partial control information required for scheduling the second TTI, where the first control information and the third control information are corresponding to complete control information required for scheduling the second TTI.

Abstract: This application provides a control information transmission method, a base station, and a terminal. The method includes: extracting a radio resource from a preset resource block set, and sending control information in a first time period by using the radio resource. The base station includes a processor and a transmitter. The processor is configured to extract a radio resource from a preset resource block set, and the transmitter is configured to send control information in a first time period by using the radio resource. According to the control information transmission method provided in this application, the base station can send the control information in any time period, and the terminal can receive the control information in any time period, thereby shortening a time interval between two control information transmissions.

Abstract: A method for sending and receiving a HARQ-ACK message is provided. The method includes: A terminal device selects a first PUCCH resource from at least one first PUCCH resource set based on a first time subunit. The first time subunit is a time subunit in which the HARQ-ACK message is located. The first PUCCH resource is a PUCCH resource in the first time subunit. The at least one first PUCCH resource set is configured by a network device for the terminal device based on a time unit. The terminal device sends the HARQ-ACK message to the network device based on the first PUCCH resource.

Abstract: This application provides an uplink control information transmission method. In a scenario in which uplink preemption occurs, the hybrid automatic repeat request (HARQ) acknowledgement information is transmitted on a physical uplink control channel (PUCCH) resource pre-configured at a higher signaling layer. In some embodiments, when the first uplink resource is a PUCCH resource used after the HARQ acknowledgement information is multiplexed or a physical uplink shared channel (PUSCH) resource used after the HARQ acknowledgement information is multiplexed, the HARQ acknowledgement information may be sent on the PUCCH resource that is used before the HARQ acknowledgement information is multiplexed, if the PUCCH resource is available. In some embodiments, when the first uplink resource is a PUSCH resource that is used after the HARQ acknowledgement information is multiplexed, a resource area in which a PUSCH is not occupied may be searched for a new PUCCH resource.
