摘要： This application discloses a carrier switching solution for multi-carrier communication. A network device sends configuration information to a terminal. The configuration information includes first uplink carrier information and second uplink carrier information. The first uplink carrier information indicates that a first uplink carrier is an SRS switching-from uplink carrier. The second uplink carrier information indicates that a second uplink carrier is an SRS switching-to uplink carrier. At least one of the first uplink carrier and the second uplink carrier belongs to a cell including a supplementary uplink (SUL) carrier. The terminal may determine the SRS switching-from uplink carrier and the SRS switching-to uplink carrier in a plurality of configured uplink carriers based on the configuration information.

摘要： A signal demodulation method, a signal transmission method, and a related apparatus. The signal demodulation method includes: a terminal device receives a first tracking reference signal from a first transmission reception apparatus of a single frequency network cell; a second tracking reference signal occupying different time-frequency from the first tracking reference signal from a second transmission reception apparatus of the single frequency network cell; and receives indication information indicating tracking reference signals from the first transmission reception apparatus or the second transmission reception apparatus; determines, based on the one or more tracking reference signals for receiving the downlink signal, a first carrier frequency on which the downlink signal is to be received; receives the demodulation reference signal and the downlink data based on the first carrier frequency; and demodulates the downlink data based on the demodulation signal.

摘要： A first access network device receives an addition request message from a second access network device. The first access network device determines a third uplink carrier used by a terminal to send a preamble to the first access network device, and sends an addition request acknowledgement message to the second access network device. The addition request acknowledgement message includes carrier indication information. The carrier indication information indicates the third uplink carrier. The third uplink carrier is at least one of the first uplink carrier or a second uplink carrier. The second uplink carrier and the first uplink carrier belong to a same cell of the first access network device and the second uplink carrier is a supplementary uplink carrier.
