Abstract: The present disclosure relates to resource indication methods and apparatus. In one example method, a network device configures resource configuration information for a terminal device. The terminal device determines channel state information based on the resource configuration information, and sends the channel state information. The resource configuration information is used to indicate a first reference signal resource set, L second reference signal resource sets, and a type of the first reference signal resource set. The first reference signal resource set includes resources for M first reference signals, and a resource for one of the M first reference signals is used to measure a channel.

Abstract: The present disclosure relates to information transmission methods and apparatus. In one example method, a terminal obtains first spatial parameter information of a first channel. The terminal receives the first channel based on the first spatial parameter information. The first channel is one of multiple candidate control channels in a first control resource set. The first control resource set is configured by using a master information block (MIB), a system information block type 1 (SIB 1), or a physical downlink control channel (PDCCH) common configuration parameter.

Abstract: This application provides a data transmission method and apparatus. The method includes: A terminal device determines an actual transmit power for first uplink data based on a determined channel transmit power and a transmission parameter. The actual transmit power is less than or equal to the channel transmit power, and the transmission parameter includes one or more of parameters that can be used to indicate a location of the terminal device. The terminal device sends the first uplink data at the actual transmit power. Therefore, the terminal device may determine the actual transmit power for the uplink data based on the channel transmit power and various transmission parameters that can indicate whether the terminal device is located at a cell edge, so that the actual transmit power for the uplink data can be flexibly adjusted, thereby improving data transmission reliability.

Abstract: 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.
