Document Type and Number:
WIPO Patent Application WO/2022/231175
Kind Code:
A1
Abstract:
A method and a device for coherent communication are disclosed. An operating method of a terminal comprises the steps of: receiving, from a first TRP, an RRC message including information indicating the performance of reception operations for the first TRP and a second TRP; performing the reception operations for the first TRP and the second TRP to receive a common DL-RS; and allowing communication with the first TRP and/or the second TRP on the basis of the common DL-RS, wherein the common DL-RS is co-transmitted in the first TRP and the second TRP.
