    Abstract: This application discloses a reference signal transmission method and an apparatus. A network node sends reference signals by mapping the reference signals to at least one resource unit, where the at least one resource unit includes a plurality of sub-resource units; and the network node receives, from the terminal, measurement information related to part of the plurality of sub-resource units. The terminal selects, based on configuration information of the reference signals, part of the measurement information to report, so that a quantity of channel resources occupied by the measurement information is reduced.

    Abstract: This application provides a phase tracking reference signal (PTRS) sending method and apparatus. The method includes: implicitly determining, by a terminal device based on obtained uplink grant information and a preset rule, a to-be-sent PTRS and an antenna port for carrying the to-be-sent PTRS, where the antenna port is selected from an antenna port set, and the to-be-sent PTRS is one or more of all available PTRSs; and putting the to-be-sent PTRS on the antenna port, and sending the to-be-sent PTRS on the antenna port. This implicit indication method can effectively reduce air interface signaling overheads and improve air interface efficiency.

    Abstract: Embodiments of this application provide an information transmission method and a device. The method includes: sending, by a first device, M signals to a second device through N ports, where N and M are integers, and M≥N≥2; and receiving, by the first device, measurement information sent by the second device, where the measurement information is determined by the second device based on the M signals, and the measurement information is used to indicate a relationship between the N ports. Therefore, in the embodiments of this application, the relationship between the ports is determined by using characteristics of the ports on a side of the second device, so that the first device can relatively accurately determine the relationship between the ports, and the first device can perform appropriate communication management on the plurality of ports. This improves performance of transmission between the first device and the second device.

    Abstract: Embodiments of the present invention relate to the communications field, and disclose an information transmission method and device to implement beamforming on an SRS. A specific solution is as follows: A base station configures at least one first resource for a UE, where the first resource is used by the UE to transmit a target channel and/or signal; and the base station transmits first indication information to the UE, where the first indication information is used to indicate a correspondence between the first resource and a beam, or the first indication information is used to indicate a correspondence between the first resource and a second resource. The embodiments of the present invention are used in a beamforming process.
