Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a communications system, to determine a physical resource block (PRB) grid when a center frequency of a synchronization signal (SS) is inconsistent with a center frequency of a carrier. The method includes: receiving, by a terminal, an SS from a network device; determining, by the terminal, a first PRB grid based on the SS; receiving, by the terminal, first indication information from the network device, where the first indication information is used to indicate a first frequency offset between the first PRB grid and a second PRB grid; and determining, by the terminal, the second PRB grid based on the first PRB grid and the first frequency offset.

Abstract: This application provides a data communication method, a terminal, and a base station. In one embodiment, the terminal receives a first demodulation reference signal based on a first physical resource block index. The first physical resource block index is determined based on a first location in frequency domain, and the first demodulation reference signal is used to demodulate a data channel on which system information is located. The terminal sends and/or receives a second demodulation reference signal based on a second physical resource block index. The second physical resource block index is determined based on a second location in frequency domain, and the second demodulation reference signal is used to demodulate a data channel other than the data channel on which the system information is located.

Abstract: The application relates to allocating transmission resources in communication networks that provide low latency services. A terminal receives, from a base station time-frequency resource division information, which indicates a division of a time-frequency resource that is allowed to be used by another service. The division of the time-frequency resource includes one or more resource units in time domain and one or more resource units in frequency domain. The terminal further receives from the base station time-frequency resource indication information, which indicates that, in the time-frequency resource that is allowed to be used by the other service, at least one time domain resource unit and at least one frequency domain resource unit are occupied by the other service. The terminal communicates with the base station using the time-frequency resource except the at least one time-domain resource unit and at least one frequency-domain resource unit that are occupied by the other service.

Abstract: A method, system, and device for resource block (RB) indexing in a user equipment (UE) is provided. In an embodiment, the method includes obtaining, at the UE, a UE-independent frequency reference point. The method also includes determining, by the UE, a UE-independent index of an RB according to the UE-independent frequency reference point.
