  • Patent number: 10912120
    Abstract: Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.

  • Patent number: 10892868
    Abstract: This application provides a data transmission method and an apparatus, in which two radio access network devices share a resource. A first radio access network device determines a resource occupation status corresponding to a different status of a second access network device on a shared resource. The first radio access network device indicates the resource occupation status to a terminal device served by the first radio access network device. The terminal device determines an available resource in a shared carrier based on the resource occupation status, and communicates with the first access network device using the available resource. The first radio access network device can perform communication on the shared resource regardless of a status of the second radio access network device on the shared resource, so that the two radio access network devices flexibly and efficiently coexist in the shared carrier. This improves utilization of the shared resource.
