Abstract: An uplink reference signal transmission method is disclosed. User equipment receives first configuration information of a first uplink measurement reference signal and second configuration information of a second uplink measurement reference signal from a wireless network device. The first configuration information is used to configure a time-frequency resource of the first uplink measurement reference signal, and the second configuration information is used to configure a time-frequency resource of the second uplink measurement reference signal. The first uplink measurement reference signal is a zero-power uplink measurement reference signal, and the second uplink measurement reference signal is a non-zero-power uplink measurement reference signal. The user equipment sends, based on the first configuration information and the second configuration information, the second uplink measurement reference signal on a time-frequency resource, other than the time-frequency resource of the first uplink measurement reference signal, in the time-frequency resource of the second uplink measurement reference signal.

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.
