摘要： The present disclosure relates to power indication methods and apparatus. In one example method, a terminal generates antenna transmit capability information, where the antenna transmit capability information is used to indicate whether a maximum transmit power value of each transmit antenna port of the terminal reaches a preset power value, or the antenna transmit capability information is used to indicate a maximum transmit power value of each transmit antenna port of the terminal. Then, the terminal sends the antenna transmit capability information to a network device.

摘要： This application provides a communications method and apparatus, to improve uplink transmission performance. The method includes determining, by a terminal device, capability indication information and sending the capability indication information to a network device. The capability indication information is used to determine a power scaling factor, the power scaling factor is a ratio of a sum of actual transmit power of n non-zero antenna ports to channel transmit power, and a maximum value of the channel transmit power is a rated maximum transmit power of a system.

摘要： A communication method and apparatus are provided, so that a terminal device determines whether DCI obtained through monitoring is repeatedly transmitted on a PDCCH or individually transmitted on a PDCCH. A network device determines first configuration information based on a first condition, and sends the first configuration information to a first terminal device. The first configuration information includes information indicating the first terminal device to monitor a PDCCH candidate based on a span, and includes configuration information of a first PDCCH candidate and a second PDCCH candidate.

摘要： This application provides an example communication method and an example apparatus. The method includes a first network device generates first indication information to indicate a first downlink resource. Second indication information indicates a second downlink resource. Because the first indication information may indicate whether the second indication information exists, if a terminal device detects the first indication information in the first time unit, and the first indication information indicates that the second indication information does not exist in the first time unit, the terminal device may stop a blind detection process on the second indication information in advance.
