Communication method and device

Abstract

A communication method and a device, applied to the technical field of communications. The method comprises: a first device determines a first reference signal. The first device may determine a second reference signal, and send the first reference signal and the second reference signal, wherein a first sequence group is associated with the geographic location of the first device, a sequence group corresponding to the first reference signal is the first sequence group, and a sequence group corresponding to the second reference signal is the first sequence group; and / or the first device may send the first reference signal, and a resource carrying the first reference signal is associated with the geographic location of the first device. In the method, a sequence group corresponding to a reference signal is associated with the geographic location of the first device, and / or a resource carrying the reference signal is associated with the geographic location of the first device, so that a second device can determine the geographic location of the first device, thereby allowing the second device to perform optimization on the basis of the geographic location of the first device.
