Abstract

The invention relates to a reference signal sending method and device, a reference signal receiving method and device, a base station, user equipment and a computer readable storage medium. The reference signal sending method comprises: determining a plurality of sendable positions of a reference signal, the plurality of sendable positions at least comprising an initial sendable position; and in response to the fact that the transmittable position used for transmitting the reference signal is idle in the plurality of transmittable positions, transmitting the reference signal in the idle transmittable position, wherein the reference signal index carried by the reference signal comprises the reference signal index corresponding to the initial sendable position and the offset between the idle sendable position and the initial sendable position. According to the embodiment of the invention, the sending opportunity of the reference signal is increased.

Description

[0001] Divisional Application Statement [0002] This application is based on the divisional application of the Chinese invention patent application with the application number CN 201880001030.0 and the application date of July 11, 2018, and the invention name is "Reference Signal Receiving Method and Device, Base Station and User Equipment". technical field [0003] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for sending a reference signal, a method and device for receiving a reference signal, a base station, user equipment, and a computer-readable storage medium. Background technique [0004] Under the New Radio (NR, NR for short) licensed spectrum, each time slot (slot) includes 14 symbols, and how many slots are included in 1 millisecond (ms) is determined by the subcarrier spacing. For example, when the subcarrier spacing is 15 kilohertz (KHz), there is 1 slot in 1ms; when the subcarrier spacing is...
