Abstract: This application provides a communication method, including: A terminal device receives configuration information from a network device. The configuration information is used to configure at least two frequency bands for the terminal device, and the at least two frequency bands include a first frequency band and a second frequency band. The terminal device receives first scheduling information from the network device. The first scheduling information indicates a target resource block (RB) for data transmission. The terminal device performs data transmission with the network device on a same symbol by using a first RB on the first frequency band and a second RB on the second frequency band. There is a first common resource block (CRB) deviation between the first RB and the second RB, and the target RB includes the first RB or the second RB.

Abstract: This application provide a resource indication method and a related device. According to the method provided in this application, a terminal device can send a HARQ-ACK on a PUCCH resource in at least one sub-slot. The resource indication method may be applied to the terminal device. The method may include: The terminal device may receive DCI from a network device, where the DCI indicates a slot used by the terminal device to transmit a HARQ-ACK. After receiving the DCI, the terminal device may send the HARQ-ACK on a PUCCH resource in at least one sub-slot of the slot indicated by the DCI. The slot includes at least two sub-slots. In other words, the terminal device may send the HARQ-ACK on a PUCCH resource in one sub-slot of the slot, or may send the HARQ-ACK on a PUCCH resource in a plurality of sub-slots of the slot.

Abstract: A DRX control method and apparatus may flexibly control active times of different DRXs when a plurality of DRXs is configured for a terminal device. For example, a network device may send indication information to the terminal device in a first serving cell of the terminal device, to configure the terminal device to start, prolong, or end DRX active time of a second serving cell of the terminal device. The first serving cell is configured with a first DRX, and the second serving cell is configured with a second DRX. The network device sends indication information based on the first DRX.

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.
