Abstract: Embodiments of the present invention provide a data transmission method and device. The method includes: when a resource position of a first data packet is preempted, generating, by a first device, first indication information, where the first indication information is used to indicate information about the preempted resource position of the first data packet; and sending, by the first device, the first indication information to a second device, so that the second device receives the first data packet based on the first indication information.

Abstract: A weight determining method and a related apparatus, to reduce a beam gain loss caused by a beam selection deviation are described. The method includes receiving an uplink reference signal and obtaining a channel reciprocity parameter between an uplink channel and a downlink channel based on the uplink reference signal. The method further includes determining state information of the downlink channel based on the channel reciprocity parameter, carrier frequency information of the uplink channel, and carrier frequency information of the downlink channel. Moreover, the method includes determining a weight of a downlink reference signal based on the state information of the downlink channel.
