REFERENCE SIGNAL TRANSMITTING METHOD, RECEIVING METHOD AND DEVICE
FIG3 is a schematic diagram of an indication of group information of reference signal ports according to an embodiment of this application
As shown in FIG3, an indication of the first group information includes: in the first group information, port numbers 0, 1, 4, and 5 are grouped into one group, and port numbers 2, 3, 6, and 7 are grouped into one group. After receiving the port group information, the UE determines, according to the indication of the port group information, the antenna port group number k for transmitting the reference signal at the time n. Further, according to the indication of the reference signal port group information, the UE determines the port group number k used every time the reference signal is transmitted, where each port group includes at least one antenna port. For example, in a channel measurement process, a reference signal is transmitted for four times, and the following four reference signal port groups are used for transmission at the four times respectively, where port numbers corresponding to each reference signal port group are: {0, 1, 4, 5}, {2, 3, 6, 7}, {2, 3, 6, 7}, and {0, 1, 2, 3}.
