Title:
DRS SENDING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/154923
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a DRS transmission method and apparatus, which relate to the communication field and increase the sending opportunities of measurement reference signals in an unlicensed spectrum so as to improve the efficiency of beam management. The method specifically comprises: a network device performing carrier sensing, determining that a carrier is idle, and acquiring an MCOT in a DMTC; in the MCOT, using an idle carrier to send a first signal of a target beam, wherein the first signal comprises a DRS sent to the target beam and a measurement reference signal sent to N beams.
