摘要： This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

摘要： This application provides a physical downlink control channel transmission method and a related apparatus. The transmission method includes: A network device sends a resource configuration, where the resource configuration indicates a time domain resource used by the network device for PDCCH sending. The network device sends a PDCCH of a first terminal device on a first time domain resource in the time domain resource used by the network device for PDCCH sending, and sends a PDCCH of a second terminal device on a second time domain resource in the time domain resource used by the network device for PDCCH sending. In this way, a terminal device needs to monitor a PDCCH only on a portion of the time domain resource used for PDCCH sending, and an increase in complexity of PDCCH monitoring of the terminal device can also be avoided.

摘要： This application provides a resource indication method and a communication apparatus. The method includes: The second node receives first indication information from the first node, where the first indication information includes first resource information, and the first resource information is associated with a first reference signal. The second node determines the first resource information based on the first indication information, where the first resource information is for limiting sending of a to-be-sent signal on a first resource indicated by the first resource information. In this way, the sending of the to-be-sent signal by the second node on the first resource is limited, so that interference of the second node to the third node can be reduced, and network performance and spectrum efficiency can be improved.
