On the basis, the Rel-13 version introduces 12-port and 16-port CSI-RS which passes through

Figure BDA0001219431020000012
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 BDA0001219431020000013
) And 16 ports are aggregated by 2 Rel-10 defined 8 ports CSI-RS (namely
Figure BDA0001219431020000014
). 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: 20. for the 32-port measurement pilot, 4 8 ports may be used for aggregation, 38 ports may be used for measurement aggregation for 24 ports, 5 4 ports may be used for aggregation for 20-port CSI-RS, and 7 4 ports may be used for aggregation for 28-port CSI-RS. However, no CSI-RS antenna array mapping method and transmission method for 20 ports or more exist at present.

The above CSI-RS mapping and transmission scheme can be applied to (N)1,N2) A 20-port antenna configuration of (2,5), as shown in fig. 2.

the number of the fifth 4-port CSI-RS (i.e., i-4) matched physical antenna or antenna element is: {33,34,40,41}, or the fifth 4-port CSI-RS (i.e., i ═ 4) is numbered: {33,34,40,41 };
the number of the sixth 4-port CSI-RS (i.e., i-5) matched physical antenna or antenna element is: {31,32,38,39}, or the sixth 4-port CSI-RS (i.e., i ═ 5) is numbered as: {31,32,38,39 };
