Abstract:
A reference signal mapping method and a reference signal mapping device are provided. The reference signal mapping method includes steps of: determining a position of a RE to which a CSI-RS has been mapped in accordance with an N-port reference signal pattern, N being equal to 12 or 16; and performing a resource mapping operation on the CSI-RS in accordance with the determined position of the RE. The position of the RE to which the CSI-RS has been mapped in the N-port reference signal pattern being determined in accordance with a position of the RE to which the CSI-RS has been mapped in one or more of a 2-port reference signal pattern, a 4-port reference signal pattern and an 8-port reference signal pattern. As a result, it is able to achieve the 12-port or 16-port CSI-RS mapping, thereby to achieve the 12-port or 16-port CSI-RS transmission.

Claim (Index 13):
The reference signal mapping device according to  claim 12 , wherein\n positions of eight REs of twelve REs to which a group of CSI-RSs have been mapped in a 12-port reference signal pattern are identical to positions of eight REs to which a first group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the remaining four REs are distributed in one of the following five modes:\n a first distribution mode where the remaining four REs are located at positions identical to four REs to which a group of CSI-RSs have been mapped in the 4-port reference signal pattern; \n a second distribution mode where the remaining four REs are REs to which no reference signal has been mapped in the 8-port reference signal pattern; \n a third distribution mode where the remaining four REs are located at positions identical to four of the REs to which a second group of CSI-RSs have been mapped in the 8-port reference signal pattern; \n a fourth distribution mode where two of the remaining four REs are located at positions identical to two of eight REs to which the second group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the other two of the remaining four REs are located at positions identical to two of eight REs to which a third group of CSI-RSs have been mapped in the 8-port reference signal pattern; and \n a fifth distribution mode where two of the remaining four REs are located at positions identical to two of the eight REs to which the second group of CSI-RS have been mapped in the 8-port reference signal pattern, and the other two of the remaining four REs are REs to which no reference signal has been mapped in the 8-port reference signal pattern, or \n positions of four REs of the twelve REs to which a group of CSI-RSs have been mapped in the 12-port reference signal pattern are identical to positions of four of the eight REs to which the first group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the remaining eight REs are distributed in one of the following four modes:\n a sixth distribution mode where four of the remaining eight REs are located at positions identical to four of the eight REs to which the second group of CSI-RSs have been mapped in the 8-port reference signal pattern, two of the remaining four REs are located at positions identical to two of the eight REs to which the third group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the other two of the remaining four REs are REs to which no reference signal has been mapped in the 8-port reference signal pattern; \n a seventh distribution mode where four of the remaining eight REs are located at positions identical to four of the eight REs to which the second group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the other four of the remaining eight REs are located at positions identical to four of the eight REs to which the third group of CSI-RSs have been mapped in the 8-port reference signal pattern; \n an eighth distribution mode where four of the remaining eight REs are located at positions identical to four of the eight REs to which the second group of CSI-RSs have been mapped in the 8-port reference signal pattern, and the other four of the remaining eight REs are REs to which no reference signal has been mapped in the 8-port reference signal pattern; and \n a ninth distribution mode where the remaining eight REs are REs to which no reference signal has been mapped in the 8-port reference signal pattern.
