A method includes sequentially performing analog frequency conversion operations on a first digital frequency conversion signal and a second digital frequency conversion signal based on local oscillator signals at a same frequency, where the first digital frequency conversion signal corresponds to a first sounding reference signal (SRS) to be transmitted on a first carrier, and the second digital frequency conversion signal corresponds to a second SRS to be transmitted on a second carrier, transmitting the first SRS on the first carrier during a first time period, and transmitting the second SRS on the second carrier during a second time period, where the second time period is later than the first time period.

Sounding reference signal sending method and related apparatus

This application provides a signal processing method and apparatus. A network device obtains capability information of a terminal device, where the capability information includes a processing time period for uplink data of the terminal device and a processing time period for uplink control information of the terminal device; determines a first time-frequency resource based on the capability information, where the first time-frequency resource is used to carry first uplink data and/or first uplink control information; and sends first signaling to the terminal device, where the first signaling indicates the first time-frequency resource. This application can improve efficiency of configuring a time-frequency resource by the network device for the first uplink data and/or the first uplink control information of the terminal device, thereby reducing a signal transmission delay.

Signal processing method and apparatus

A method and an apparatus for determining a transmission mode of a terminal device are provided. The method includes: determining a first power configuration value and a second power configuration value of the terminal device; determining that a sum of the first power configuration value and the second power configuration value is greater than a first threshold; and determining whether the terminal device uses a first transmission mode or a second transmission mode.
