Description

Phase noise reference signal transmission method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a phase noise reference signal transmission method and device.

Background

In a wireless communication system, Phase Noise (PN) is noise caused by short-term random fluctuations in the phase of a wireless signal, and is generally caused by devices of a transmitter and a receiver. The Phase noise randomly rotates the Phase of the time domain signal, thereby causing Common Phase Error (CPE) and Inter-Carrier Interference (ICI) of the frequency domain received signal, which affect the reception of the signal.

The design goal of 3GPP for 5G new communication system is to develop a frequency band at least as high as 100GHz, and the phase noise power spectral density of the physical device crystal oscillator increases by 20dB with each 10 times increase of the carrier frequency (e.g. from 3GHz carrier to 30GHz carrier), which means that the signal of the high frequency part of the 5G system will have a large phase noise. It is also proven that the performance of the system is greatly affected if the phase noise is not suppressed to a certain extent in the high frequency part.

An important approach to phase noise is to estimate the CPE at the receiving end due to the phase noise, and then eliminate the CPE to recover a cleaner signal. An important means for estimating phase noise is to add a pilot for phase noise estimation, which is generally called a phase noise pilot or a phase noise reference signal, to a transmission signal. However, since the phase noise reference signal occupies a part of time-frequency resources, the spectrum efficiency of the system is affected.

s101, the first device determines information to be transmitted.

S102, the first equipment determines a phase noise reference signal carrying the information to be transmitted according to the information to be transmitted.

In this embodiment, the first device determines information to be transmitted that needs to be sent to the second device. In this embodiment, the phase noise reference signal sent by the first device to the second device is used to carry information sent by the first device to the second device, and since the information sent by the first device to the second device is different, in order to enable the second device to distinguish the information sent by the first device, the phase noise reference signal carrying the information is also different, that is, in this embodiment, different information to be transmitted is transmitted based on the difference of the phase noise reference signal. Therefore, after the first device determines the information to be transmitted, the phase noise reference signal for carrying the information to be transmitted is determined according to the information to be transmitted which needs to be sent.

And S104, the second equipment acquires the information to be transmitted according to the phase noise reference signal.

In this embodiment, after determining the phase noise reference signal carrying the information to be transmitted, the first device sends the phase noise reference signal to the second device. The second device receives the phase noise reference signal transmitted by the first device.

When the information to be transmitted is non-confirmed received information, the first device determines a phase noise reference signal carrying the non-confirmed received information according to the non-confirmed received information, and the phase noise reference signal is referred to as a second phase noise reference signal; then the first device sends the determined phase noise reference signal to the second device; wherein the first phase noise reference signal is different from the second phase noise reference signal. Optionally, the first phase noise reference signal and the second phase noise reference signal are opposite to each other, and if the first phase noise reference signal is the sequence a (n), the second phase noise reference signal is the sequence-a (n).

In some embodiments, the information to be transmitted is a resource indication. The resource indication is used for indicating the first device to transmit data at a preset time interval after the current time interval.

The method comprises the steps that a second device receives a phase noise reference signal sent by a first device, whether information to be transmitted is a resource indication or not is determined according to whether the phase noise reference signal is a first phase noise reference signal or a second phase noise reference signal, and when the phase noise reference signal is the first phase noise reference signal, the second device obtains the resource indication so as to know that the first device continues to send data at a preset time interval after the current time interval; and when the phase noise reference signal is the second phase noise reference signal, the second equipment learns that the first equipment does not continuously send data according to the second phase noise reference signal.

The resource indication is used for indicating the first device to transmit data at an nth time interval after the current time interval, where N is an integer greater than or equal to 1, and the phase noise reference signals carrying the resource indication are different from each other according to different values of N.

And the network equipment determines a third phase noise reference signal according to the third TPC information. And the terminal receives the third phase noise reference signal and acquires third TPC information so as to acquire that the transmitting power of the terminal is kept unchanged.
