Title:
METHOD FOR SENDING REFERENCE SIGNAL AND DEVICE FOR SENDING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2018/028570
Kind Code:
A1
Abstract:
A method for sending a reference signal, a method for receiving a reference signal, a device for sending a reference signal, and a device for receiving a reference signal. The method for sending a reference signal comprises: a first sending device determining a first reference signal and a first code resource, the first code resource being orthogonal to a second code resource, the second code resource being used for transmitting a second reference signal, the first reference signal being a reference signal of a first type, and the second reference signal being a reference signal of a second type; and the first sending device using the first code resource to send the first reference signal. The first reference signal is carried in at least one first time-frequency resource group, the number of resource elements (REs) occupied by each first time-frequency resource group among the at least one first time-frequency resource group being equal to the length of the first code resource, and the time-frequency resources occupied by the at least one first time-frequency resource group are multiplexed for the first reference signal and the second reference signal , on the basis of the first code resource and the second code resource, thereby reducing the overhead of the time-frequency resources.
