REFERENCE SIGNAL TRANSMITTING METHOD, RECEIVING METHOD AND DEVICE
FIG6 is a schematic structural diagram of an apparatus for transmitting a reference signal according to an embodiment of this application  FIG4 is a schematic diagram of another indication of group information of reference signal ports according to an embodiment of this application
Another embodiment of this application further provides an apparatus for transmitting a reference signal. The apparatus is configured to implement the method for transmitting a reference signal in the foregoing embodiment. The apparatus is disposed in a second network device, and the second network device includes a terminal device. As shown in FIG6, the apparatus for transmitting a reference signal includes a receiving unit 601, a processing unit 602, and a transmission unit 603. In addition, the apparatus may further include other functional units or modules such as a storage unit. In this embodiment of this application, the transceiver 1301 may be configured to receive reference signal port group information transmitted by the first network device, transmit a reference signal to the first network device, and the like in the foregoing embodiment. In FIG6 of the foregoing apparatus embodiment, functions to be implemented by the receiving unit 601 may be implemented by the transceiver 1301 of the terminal device, or implemented by the transceiver 1301 controlled by the processor 1302. Functions to be implemented by the processing unit 602 in FIG6 may also be implemented by the processor 1302 of the terminal device.  As shown in FIG4, FIG4 is an implementation of another indication of the first group information. The implementation specifically includes: the UE transmits the reference signal for six times according to the received reference signal port group information, and the reference signal is transmitted every time on a port group including two ports. Further, the UE determines that port numbers used when the reference signal is transmitted every time in the six times are {0, 1}, {1, 2}, {2, 3}, {3, 4}, {4, 5}, and {5, 6} respectively, and then the UE performs switching according to the grouped antenna port numbers and transmits the reference signal sequentially.
