A wireless communication method and apparatus for improving communication failure recovery efficiency. The method is applied to a terminal or a chip used in a terminal, and includes: upon detecting that downlink communication of the first serving cell fails, determining that downlink communication of the second serving cell is normal; sending a communication failure recovery request on an uplink channel of the second serving cell, where the communication failure recovery request is used to request to recover from a downlink communication failure of the first serving cell; and detecting a communication failure recovery response on a downlink channel of the second serving cell, where the communication failure recovery response is used to indicate a downlink communication resource of the first serving cell.

Wireless communication method and apparatus

This application provides a method and an apparatus for determining transmit power. The method includes: A terminal device determines a first bit rate of channel state information part 1 CSI-1, where the first bit rate is a bit quantity of the CSI-1 carried on each resource element for transmitting the CSI-1; and the terminal device adjusts transmit power of a physical uplink shared channel PUSCH based on the first bit rate, where the PUSCH is used to carry the CSI-1.
