The invention provides a transmitting method of a phase noise compensation reference signal, an estimation method and communication equipment. The transmitting method of the phase noise compensation reference signal comprises the following steps: determining N phase noise compensation reference signals, wherein each phase noise compensation reference signal is corresponding to one reference signalport, each phase noise compensation reference signal is corresponding to one or more transmitting antennas or antenna ports, the number of the transmitting antenna or the antenna port is Nt, and N isless than Nt; pre-coding a to-be-sent data flow and a demodulation reference signal corresponding to the data flow to obtain the pre-coded data flow and demodulation reference signal, and mapping thepre-coded data flow and demodulation reference signal to Nt transmitting antennas or antenna ports to transmit, and mapping N phase noise compensation reference signals to Nt transmitting antennas orantenna ports to transmit; and informing the pre-coding matrix information adopted by pre-coding to a receiving end. The scheme provided by the invention can accurately estimate the phase noise of each transmitting / receiving radio frequency channel.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method of a phase noise compensation reference signal, a phase noise estimation method, a transmitter, a receiver and a communication device. Background technique [0002] Phase noise comes from the local oscillators in the transmitter and receiver, which will affect the transmission of multi-carrier signals. In the high frequency band (above 6GHz), the impact of phase noise will be more serious, and it is necessary to compensate the phase noise of the received signal to ensure system performance. By introducing a phase noise compensation reference signal at the transmitting end, it can be ensured that the receiving end can estimate the phase noise of the link and compensate the received signal. [0003] Since the LTE (Long Term Evolution, long-term evolution) system is applied in a low frequency band, there is no corresponding reference signal design for p...
