Abstract

The invention provides a reference signal transmission method and transmission device, solving the problem that a certain reference signal where a resource collision occurs is usually punched when theresource collision occurs between two reference signals, so that the function of the reference signal cannot be fulfilled, and the communication performance is affected. The reference signal transmission method comprises the following steps: when resource positions of two preset reference signals meet a preset resource collision condition, a subcarrier position of a first preset reference signalof the two preset reference signals is moved, so as to obtain a target subcarrier position of the first preset reference signal; wherein the target subcarrier position is a frequency domain position except for a frequency domain position corresponding to the subcarrier of a second preset reference signal in a target physical resource block PRB (physical resource block) where the first preset reference signal is located; therefore the resource collision is avoided when the first preset reference signal and the second preset reference signal are transmitted, the performance of each reference signal is improved, and the reliability of a communication link is effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a reference signal transmission method and transmission equipment. Background technique [0002] For the future-oriented fifth-generation (5Generation, 5G) mobile communication system, in order to achieve the target of 20Gbps downlink transmission rate and 10Gbps uplink transmission rate, high-frequency transmission technology and large-scale antenna array technology have attracted much attention. [0003] High-frequency bands have more abundant spectrum resources, but the transmission distance is limited due to large attenuation; while large-scale antenna arrays can provide greater beamforming gain, but the antenna aperture is usually larger. However, the two can be combined: the short-wavelength characteristics of high-frequency bands will reduce the aperture of large-scale antenna arrays, making dense deployment of antennas easier and more feasible; ...
