Title: METHOD AND TERMINAL DEVICE FOR TRANSMITTING REFERENCE SIGNAL
Abstract:
Provided are a method and a terminal device for transmitting a reference signal. The method comprises: a first terminal device acquiring a first reference signal set and a second reference signal set, the first terminal device having n antenna ports; sending, on a first time-frequency resource of an i-th antenna port, a first reference signal to a second terminal device, the i-th antenna port being any one of the n antenna ports; sending, on the first time-frequency resource of a j-th antenna port, a second reference signal to the second terminal device, the j-th antenna port being one of the remaining antenna ports of the n antenna ports other than the i-th antenna port; and sending, on each of the n antenna ports, at least one reference signal in the first reference signal set, such that the second terminal device can perform RSRP measurement on the basis of an old pilot sequence, thereby learning the time-frequency resource occupation of each antenna port.
