Abstract: A terminal determines a first frequency for accessing the network device Then, the terminal determines at least one second frequency based on the first frequency, where any second frequency is different from the first frequency, and at least two second frequencies are also different. The terminal selects at least two different second frequencies from the first frequency and the at least one second frequency. The terminal separately receives, in a time unit in a period by using the at least two different frequencies, an SSB from the network device. The terminal accesses the network device based on received one or more different SSBs.

Abstract: The disclosure provides transmission methods and apparatuses. One example includes sending control signaling to a terminal device, to indicate the terminal device to send a physical uplink shared channel (PUSCH) on a first frequency band; and receiving the PUSCH sent by the terminal device on the first frequency band. The first frequency band includes at least one guard subcarrier. A quantity of the at least one guard subcarrier is determined based on a Doppler frequency shift of a beam covering the terminal device. The first frequency band is located on a frequency band corresponding to the beam.

Abstract: This application discloses example signal sending methods and apparatuses, and example signal processing methods and apparatuses. One example method includes generating, by a terminal device, a channel sounding reference signal (SRS). The terminal device can then send the SRS to a target base station, where the target base station detects, by using the SRS, that a change range of an uplink timing location of the terminal device is not less than a length of one SRS symbol.
