Description

Phase noise reference signal transmission method and apparatus

technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and apparatus for transmitting a phase noise reference signal.

Background technique

In a wireless communication system, phase noise (phase noise, PN) is a noise caused by short-term random fluctuations in the phase of a wireless signal, which is usually caused by components of a transmitter and a receiver. Phase noise causes the phase of the time-domain signal to rotate randomly, which brings about common phase error (CPE) and inter-carrier interference (ICI) of the received signal in the frequency domain, which affects signal reception.

3GPP's design goal for 5G new communication systems is to develop frequency bands up to at least 100GHz, and the phase noise power spectral density of physical device crystal oscillators increases by 20dB for every 10-fold increase in carrier frequency (such as from 3GHz carrier to 30GHz carrier). , which means that the signal in the high-frequency part of the 5G system will have a lot of phase noise. At present, it has also been proved that if the phase noise is not suppressed to a certain extent in the high frequency part, the performance of the system will be greatly affected.

An important way to deal with phase noise is to estimate the CPE caused by the phase noise at the receiving end, and then eliminate it to restore a relatively clean signal. An important method for estimating phase noise is to add a pilot for phase noise estimation into the transmitted signal, which is usually called a phase noise pilot or a phase noise reference signal. However, since the phase noise reference signal occupies a part of the time-frequency resources, the spectral efficiency of the system is affected.
