The present invention provides a reference signal transmission method, base station and terminal, which solves the problem that when the reference signals collide with each other, punching a certain reference signal that collides cannot realize the function of the reference signal and affect the communication performance. . The transmission method of the present invention includes: selecting N or N-1 target reference signals from N preset reference signals; using a preset function, within the preset frequency hopping range, the resource position of each target reference signal Perform frequency hopping processing to obtain the target resource position of each target reference signal; perform transmission of the target reference signal with the terminal on the target resource position. In the embodiment of the present invention, by performing frequency hopping processing on the resource position of each target reference signal, the resource position occupied by each target reference signal is randomized, thereby reducing the probability of resource collision of reference signals, and further improving the resource position of each target reference signal. The performance of the signal effectively guarantees the reliability of the communication link.
Description
technical field [0001] The present invention relates to the technical field of communication applications, in particular to a reference signal transmission method, a base station and a terminal. 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 feasib...
