Between be spaced fixed quantity subcarrier.
For the reference signal of N-port, when the value of N is smaller, such as N=2, the figure of the reference signal of 2 ports
Sample can be only one kind, can only include one in reference signal pattern set corresponding to the reference signal of 2 ports in such cases
A reference signal pattern.
Figure 3 above and Fig. 4 exemplarily only show the pattern set and 16 port CSI-RS of 24 port CSI-RS
Pattern set, but the application is not limited in the pattern set that above-described embodiment provides.In the embodiment of the present application, N-port reference
The corresponding reference signal pattern set of signal can be predefined by system, and for well known to wireless network access nodes and terminal.
In the embodiment of the present application, each of reference signal pattern set corresponding for N-port reference signal is with reference to letter
Number pattern, can arranging a reference resources unit, (for example one with reference to RE).According to the corresponding reference of a reference signal pattern
The time-frequency location of resource unit may be used to determine the running time-frequency resource position that the reference signal pattern occupies in a PRB.
Reference resources unit corresponding to one reference signal pattern can be in the occupied RE of the reference signal pattern
One, specifically which RE can make an appointment, and well known to RAN node and terminal.For example, can will have in reference pattern
There is the resource unit of minimum notation index and minimum sub-carrier indices, as the corresponding reference resources unit of the reference pattern.
For example, having minimum symbol in 4 CSI-RS patterns of 24 port CSI-RS shown in Fig. 3, in reference pattern
Index and the resource unit (i.e. the RE of figure bend filling) of minimum sub-carrier indices are that corresponding pattern is corresponding with reference to RE.
For another example, there is minimum symbol in 6 CSI-RS patterns of 16 port CSI-RS shown in Fig. 4, in reference pattern
Number index and the resource unit (i.e. the RE of figure bend filling) of minimum sub-carrier indices are that corresponding pattern is corresponding with reference to RE.

Pattern, the predefined reference resources unit (RE) of system are 16 port CSI-RS of composition with minimum OFDM symbol index and minimum
The RE (such as RE of figure bend filling) of sub-carrier indices.
Process according to figure 5 configures a 16 port CSI-RS, 16 port CSI-RS in S501 for terminal
Using pattern 3;In S502, RAN node is by port number N=16, the index (such as value be 3) and reference resources of pattern 3
Time-frequency location (k, l) where unit is by signaling to terminal, wherein k indicates sub-carrier indices, and l indicates OFDM symbol
Index, here, k=6, l=2.In S503, terminal receives port number N=16, the pattern 3 for the CSI-RS that RAN node end is sent
Index and reference resources unit time-frequency location information (k, l);In S504, terminal is according to above- mentioned information and system
It is predefined, determine the running time-frequency resource position of this 24 port CSI-RS.Specifically, in S504, terminal is obtained according to port number 16
Corresponding CSI-RS pattern set determines the pattern 3 in the pattern set according to drawing indexing value 3, according to reference resources unit
The time-frequency location (6,2) at place simultaneously combines pattern 3, determines that the RE 2~5 and RE 8~11 in OFDM symbol 6,7 are CSI-RS
The RE of occupancy, as shown in fig. 7, to receive CSI-RS on corresponding running time-frequency resource, and carry out channel measurement and CSI calculating.
