Abstract
Embodiments of this application disclose a sounding reference signal scheduling method, a sounding reference signal sending method, and apparatuses thereof. The sounding reference signal scheduling method comprises: determining an available carrier in an unlicensed spectrum; and in response to the existing available carrier, sending, at least on the available carrier, a physical indication signal, wherein the physical indication signal comprises information related to scheduling of a sounding reference signal of at least one user equipment, and the physical indication signal is used at least to trigger the at least one user equipment to send a sounding reference signal. According to the methods and apparatuses in the embodiments of this application, scheduling information is placed in a physical indication signal that occupies an available carrier; therefore, a sounding reference signal can be scheduled more flexibly.
