[0082] Fig. 2 is a schematic diagram of positions of measurement reference signals in physical resource blocks according to the first embodiment of the present invention. In the case where the cyclic prefix is a regular cyclic prefix, the position of the measurement reference signal in the physical resource block is as follows Figure 2a As shown, in the case where the cyclic prefix is an extended cyclic prefix, the position of the measurement reference signal in the physical resource block is as follows Figure 2b shown.
[0083] In this embodiment, assuming that the number of newly added measurement reference signals is 8, the measurement reference signals are divided into K=8 reference signal groups, and each reference signal group includes measurement reference signals of one antenna logic port. The eight reference signal groups are recorded as: {#0}, {#1}, {#2}, {#3}, {#4}, {#5}, {#6}, {#7}.
[0084] In addition, in this example, P 1 =P 2 =...=P K =P=P max .
