Abstract:
1. A method for mapping downlink dedicated pilots to resource elements in an Extended Cyclic Prefix (Extended CP) frame, applied in a Long Term Evolution (LTE) system, comprising: mapping the first downlink dedicated pilot of a port to the 5 mapping the second downlink dedicated pilot to the 5 mapping the third downlink dedicated pilot to the 5 mapping the fourth downlink dedicated pilot to the 5 mapping the fifth downlink dedicated pilot to the 8 mapping the sixth downlink dedicated pilot to the 8 mapping the seventh downlink dedicated pilot to the 8 mapping the eighth downlink dedicated pilot to the 8 mapping the ninth downlink dedicated pilot to the 12 mapping the tenth downlink dedicated pilot to the 12 mapping the eleventh downlink dedicated pilot to the 12 mapping the twelfth downlink dedicated pilot to the 12 transmitting the Extended CP frame with the downlink dedicated pilots to a user equipment; wherein, only one port of downlink dedicated pilots is transmitted in the physical resource block.
