US 2020/0092036 A1 · METHOD FOR TRANSMITTING CSI-RS AND BASE STATION

Abstract

Methods for transmitting a channel state information-reference signals (CSI-RS) and a base station are provided, where the example method includes aggregating, by the base station, first configuration modes of K CSI-RSs to form a second configuration mode of the CSI-RSs, where K is an integer greater than or equal to 2, where each of the first configuration modes is a configuration mode of X ports, where a value of X is 2, 4, or 8, and where the first configuration mode includes a position of a resource element corresponding to each of the X ports. The second configuration mode is a configuration mode of X*K ports, and the second configuration mode includes a position of a resource element corresponding to each of the X*K ports. The method further includes sending, by the base station, a CSI-RS to user equipment UE using the second configuration mode of the CSI-RSs.

A method for transmitting a channel state information-reference signal (CSI-RS), comprising:

aggregating, by a base station, first configuration modes of K CSI-RSs to form a second configuration mode of the CSI-RSs, wherein K is an integer greater than or equal to 2, wherein each of the first configuration modes is a configuration mode of X ports, wherein a value of X is 2, 4, or 8, and wherein the first configuration mode comprises a position of a resource element corresponding to each of the X ports, and wherein the second configuration mode is a configuration mode of X*K ports, and wherein the second configuration mode comprises a position of a resource element corresponding to each of the X*K ports;
and
sending, by the base station, a CSI-RS to a terminal using the second configuration mode of the CSI-RSs.

A base station, comprising:

at least one processor;
a memory comprising instructions;
a transmitter;
and
a system bus,
wherein the memory and the transmitter are coupled to the at least one processor using the system bus,
wherein the at least one processor is configured to aggregate first configuration modes of K channel state information-reference signals (CSI-RSs), to form a second configuration mode of the CSI-RSs, wherein K is an integer greater than or equal to 2, each of the first configuration modes is a configuration mode of X ports, a value of X is 2, 4, or 12, and the first configuration mode comprises a position of a resource element corresponding to each of the X ports;
the second configuration mode is a configuration mode of X*K ports, and the second configuration mode comprises a position of a resource element corresponding to each of the X*K ports;
and
wherein the transmitter is configured to send a CSI-RS to a terminal using the second configuration mode of the CSI-RSs obtained through aggregation by the at least one processor.
