Abstract: 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.

Abstract: A method and an apparatus for determining a scheduling user and a system. The method includes: determining a first pre-scheduling user at a second moment from a user in the first cell at a first moment; determining a first transmit weight of the first cell at the second moment; receiving a second transmit weight at the second moment that is sent by a second base station to which a second cell belongs in a data transmission system; calculating a signal to interference plus noise ratio SINR of each user in the first cell at the second moment based on the first transmit weight and the second transmit weight; and selecting a target scheduling user at the second moment from the user in the first cell based on the SINR of each user at the second moment.

Abstract: A Slow Protocol packet processing method and a related apparatus, where the method includes receiving, by a network device, a first Slow Protocol packet, determining, based on port information of a port of the network device receiving the first Slow Protocol packet, that a negotiation process is already completed between the network device and the transmit end device, querying, based on device information of the transmit end device carried in the first Slow Protocol packet, whether a device information base stored by the network device in the negotiation process includes the device information of the transmit end device, and identifying the first Slow Protocol packet as a valid packet in response to a result that the device information base includes the device information of the transmit end device.
