摘要：Embodiments of this application provide a signal transmission method andapparatus. In the embodiments of this application, a first device exchanges referencesignal configuration information with a second device, to implement coordinated
transmission of a reference signal sent by CoMP user equipment, so that the first deviceand the second device do not need to separately configure, for the CoMP user
equipment, a resource used to transmit the reference signal. In addition, the CoMP userequipment sends a same reference signal to a plurality of devices (including the firstdevice and the second device), so as to reduce delays in obtaining channel quality bydifferent devices, and improve performance of coordinated transmission.
