Description

CSI-RS mapping and transmission method and communication equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a device for mapping and transmitting Channel state information Reference Signals (CSI-RS) and a communication device.
Background
The LTE system of Rel-10 version introduces a measurement pilot, i.e., a channel state Information Reference signal (CSI-RS), wherein the measurement pilot can be configured as 2 ports, 4 ports, or 8 ports, and adopts a multiplexing mode of Orthogonal spreading Code (OCC) ═ 2, i.e., multiplexing with 2 OCC codes. In thatOn the basis, the Rel-13 version introduces 12-port and 16-port CSI-RS which passes through
Figure BDA0001123618450000011
A is provided with
Figure BDA0001123618450000012
And polymerizing the CSI-RS of the port. The 12 ports are aggregated by the 4-port CSI-RS defined by 3 Rel-10 (namely
Figure BDA0001123618450000013
) And 16 ports are aggregated by 2 Rel-10 defined 8 ports CSI-RS (namely
Figure BDA0001123618450000014
Figure BDA0001123618450000015
). Wherein the CSI-RS port numbers are used to connect each CSI-RS port to a physical antenna or antenna port having the same number. In Rel-13, for a 12-port CSI-RS and a 16-port CSI-RS with OCC ═ 2, the port numbering method takes into account the port sharing of the 16-port CSI-RS and the 8-port CSI-RS, i.e., 8 ports in the 16-port CSI-RS can be configured to legacy ues for transmitting the 8-port CSI-RS.
In order to obtain more channel information, measurement pilots of more ports are introduced in the communication system, for example: the 24 and 32 port measurement pilots may be aggregated by using 48 ports for the 32 port measurement pilots, and the 24 port measurement pilots may be aggregated by using 38 ports. However, no port numbering method for 24 ports and above CSI-RS exists at present, and no transmission mode is provided for the CSI-RS.
