Title:
METHOD, APPARATUS AND SYSTEM FOR CONFIGURING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/154193
Kind Code:
A1
Abstract:
A method, apparatus, and system for configuring a reference signal, which are used for solving the technical problem in the prior art of it not being possible to measure signal interference between backhaul links. The method comprises: a first node, as the superior node of a second node, determining first information comprising beam information of beams used by a second node and third node link, and then sending configuration information to the second node to indicate a reference signal received or sent by the second node on a target beam, wherein the target beam is at least one of the beams used by the second node and third node link, such that the first node can instruct the second node to receive or send the reference signal according to the beams used by the second node and third node link, and the second node can further measure the interference between backhaul links according to the reference signal.
