摘要： This application provides a data transmission method, to indicate resource configuration statuses of at least two groups of CRSs to a terminal device, so that the terminal device can correctly receive data, and improve data receiving performance. The method includes: receiving, by a terminal device, indication information sent by a network device, where the indication information is used to determine resources occupied by N groups of cell-specific reference signals CRSs, and N is a natural number greater than or equal to 2; and determining, by the terminal device based on the indication information, the resources that are occupied by the N groups of CRSs, and receiving data based on the resources that are occupied by the N groups of CRSs.

摘要： Embodiments of this application disclose a communication method, and a related device and system. The method includes: receiving, by a reception point, first indication information, where the first indication information is used to indicate a time-frequency resource location of a first demodulation reference signal of first data; receiving, by the reception point, second indication information, where the second indication information is used to indicate a time-frequency resource location of a second demodulation reference signal; and determining, by the reception point, a time-frequency resource location of the first data based on the time-frequency resource location of the second demodulation reference signal, and demodulating the first data based on the first demodulation reference signal. Receiving performance of the reception point can be improved. On the premise that a resource conflict does not occur, two base stations communicate with a terminal device by using a time-frequency resource allocated by a second base station.

摘要： The present invention provides a method for managing a customer edge device automatically and a PE device. The method includes: receiving, by a UNI set in a third-party operator network, an E-LMI packet sent by a VUNI set in a service provider network, where the VUNI is configured to manage a RUNI correlated with an EVC in the third-party operator network; converting, by the UNI, a unicast DMAC address in the E-LMI packet into a multicast DMAC address; and sending, by the UNI, the converted E-LMI packet to a CE device connected with the UNI. In the embodiments of the present invention, the E-LMI packet sent by the VUNI set in a service provider network may penetrate the third-party operator network, so that the management information of the service provider network can be transmitted to the CE device that is connected with the third-party operator network through the UNI, thereby managing the CE device in a cross-domain service automatically.
