Abstract: Embodiments provide a communication method, a network device, and a terminal device. Under the method, a network device can send SRS configuration information of a first transmission resource and of a second transmission resource to a terminal device. The first transmission resource is a switching source carrier or bandwidth part. The second transmission resource is a switching destination carrier or bandwidth part. The SRS configuration information of the first and second transmission resource includes a first OFDM symbol set and a second OFDM symbol set respectively. Some and all symbols in the first set and second set may be used by the terminal device to send an SRS on the first and second transmission resource respectively. In various embodiments, the network device configures one or more symbols for the terminal device to transmit an SRS, so that high-frequency channel measurement can be better supported.
