Abstract

The present disclosure relates 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. Wherein, the sending method of the reference signal includes: according to the location of the setting signal used to determine the index of the reference signal, obtain multiple transmittable positions of the reference signal, the setting signal is located in the reference signal, and the multiple transmittable positions include the reference signal The initial sendable position of the signal; channel detection is performed before sending the reference signal at each sendable position; if the channel is detected to be idle, the reference signal is sent at the corresponding sendable position. In this embodiment, multiple transmittable positions of the reference signal are obtained according to the position of the set signal used to determine the index of the reference signal, and channel detection is performed before transmitting the reference signal at each transmittable position, if the channel is detected to be idle , the reference signal is sent at the corresponding sendable position, so that the chance of sending the reference signal can be increased.

Description

technical field [0001] 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 [0002] 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 30KHz, there are 2 slots in 1ms; and when the subcarrier spacing is 60KHz, there are 4 slots in 1ms, and so on. [0003] In NR, in order to reduce the reference signal that is always on (always on), thereby reducing overhead, a Synchronization Signal Block (SSB for short) is proposed. Each SSB occupies 4 consecutive symbols, respectively in or...
