Abstract: A spectrum sharing method includes a first base station (BS) establishes a first sharing cell of a first-standard network at a shared frequency, establishes a service of a user equipment (UE) of the first-standard network in the first sharing cell, and transmits data on a Traffic Radio Bearer (TRB) of the first UE. A second BS establishes a second sharing cell at the shared frequency, and establishes a service of a second UE of the second-standard network in the second sharing cell. When the shared frequency is shared, the first BS suspends the data transmission on the TRB of the service of the first UE, and retains a common channel of the first sharing cell and a SRB of the service of the UE of the first-standard network. The second BS then starts data transmission on the TRB of the service of the second UE.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting pattern information. The method for transmitting pattern information includes obtaining pattern information; and sending the pattern information to UE. The first pattern information indicates that the spectrum of the first cell is allocated to the first RAT in a first plurality of sub-frames, and that the spectrum of the first cell is allocated to the second RAT in a second plurality of sub-frames. The first pattern information enables the UE to select any sub-frame in the first plurality of sub-frames to measure a CRS if the UE RAT pattern corresponds to the first RAT, or enables the UE to select any sub-frame in the second plurality of sub-frames to measure the CRS if the UE RAT pattern corresponds to the second RAT. The embodiments of the present invention improve scheduling accuracy and efficiency.

Abstract: This application provides a wireless communication method and a communication apparatus. The method includes a terminal device receives a data frame from a second device by using a first device, and notifies the first device when the terminal device determines that a communication data block from the first device is not successfully received. After determining a protocol data packet corresponding to the communication data block, the first device notifies the second device that the first protocol data packet is not successfully transmitted. After determining a data unit that is in the data frame and that corresponds to the communication data block, the terminal device notifies the second device through second-step feedback.

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.
