Abstract: This application provides a communication method, including: A terminal device receives configuration information from a network device. The configuration information is used to configure at least two frequency bands for the terminal device, and the at least two frequency bands include a first frequency band and a second frequency band. The terminal device receives first scheduling information from the network device. The first scheduling information indicates a target resource block (RB) for data transmission. The terminal device performs data transmission with the network device on a same symbol by using a first RB on the first frequency band and a second RB on the second frequency band. There is a first common resource block (CRB) deviation between the first RB and the second RB, and the target RB includes the first RB or the second RB.

Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communications apparatus. The method includes: A network device sends an SSB to a terminal device in a resource position of the SSB. Correspondingly, the terminal device receives the SSB. In this process, a symbol included in the resource position of the SSB does not overlap with an uplink symbol in a plurality of self-contained slot structures as much as possible. This method can reduce a probability that the symbol included in the resource position of the SSB conflicts with an uplink symbol in as many self-contained slot structures as possible, to avoid cross interference, and therefore can support reliable transmission in as many self-contained slot structures as possible.

A transmitting apparatus multiplies M first symbol sequences by M coefficients respectively to obtain M second symbol sequences, where M is a positive integer greater than 1, the symbol sequence includes L symbols, L is a positive integer greater than 1, and the M coefficients each have a magnitude of 1. The transmitting apparatus maps the M second symbol sequences onto a first time-frequency resource to obtain a frequency domain signal. The transmitting apparatus performs an IFFT operation on the frequency domain signal to obtain a time domain signal. And the transmitting apparatus sends the time domain signal.
