Problems solved by technology

However, in the CSI-RS transmission supporting 16 and 12 ports, the OCC of length 2 and the power boost of 6dB cannot fully use the power in resource block pairs
[0006] Furthermore, any CSI-RS transmission in Downlink Pilot Time Slot (DwPTS) frames in Time Division Duplex (TDD) mode is not supported in existing standards

Embodiment Construction

[0038] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0039] Considering the port limitation of the existing CSI-RS (40 resource elements supporting 5 configurations of 8 CSI-RS ports), the design of the new CSI-RS port template can combine multiple existing CSI-RS configuration. The most direct solution is that the CSI-RS model supporting 16 ports is designed as a...

Abstract

The present invention relates to a method for configuration of channel state information reference signals. The method comprises the following steps: A, generating at least three second-class channel state information reference signal configurations supporting a 12 port or a 16 port; and B, distributing the second-class channel state information reference signal configurations to at least one of the three adjacent districts belonging to the base station. Through combination of the current CSI-RS configuration, the method for configuration of channel state information reference signals constructs the CSI-RS configuration supporting the 12 and 16 ports so as to improve the system performance of the 3D-MIMO system. The configuration hopping can reduce the generation probability of the resource conflict. The present invention further provides the CSI-RS transmission supporting the 12 and 16 ports in the DwPTS frame for the TDD system.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for configuring channel state information reference signals. Background technique [0002] In a recent 3GPP meeting, a 3D Multiple Input Multiple Output (MIMO) channel model was adopted, and at the same time, a corresponding scheme for gaining gain from a 3D MIMO channel was also studied and proposed. [0003] In RAN#68, the Elevated Beamforming / Full Dimensionality (EBF / FD)-MIMO working group specified that using a 2D antenna array with cross-poles at the base station in height and direction was determined to be an improvement. The working group aims to include non-precoding and beamforming channel state information reference signal (CSI-RS: channel state information-reference signal) enhancements. Especially for the non-precoded CSI-RS, the existing CSI-RS antenna ports whose number is 1, 2, 4 or 8 are extended by using full port mapping to support 12 and ...
