Embodiment 1

[0035] In this embodiment, a method for configuring a reference signal is provided, image 3 is a flow chart of a reference signal configuration method according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps:

[0036] Step S302, configuring selection rules for phase tracking reference signals;

[0037] Step S304, according to the selection rule, select K kinds of mapping methods, and generate a phase tracking reference signal, where K is a positive integer.

[0038] Through the above steps, by defining a rule, in the communication system transmission scenario, the configuration of the phase tracking reference signal of different mapping methods can be selected. Due to the characteristics of the single carrier transmission mode, the complexity of processing the phase tracking reference signal and the The effect of adding a phase-tracking reference signal on the peak-to-average ratio of a single-carrier system. ...

[0056] In this embodiment, a device for configuring a reference signal is also provided, and the device is used to implement the above embodiments and preferred implementation modes, and those that have already been described will not be described again. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0057] Figure 5 is a structural block diagram of a device for configuring a reference signal according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:

[0058] A configuration module 50, configured to configure selection rules for phase tracking reference signals;

[0059] The processing module 52 is configured to select K mapping methods according to a s...

Embodiment 3

[0066] This embodiment is an optional embodiment according to the present invention, and is used to describe the application in detail in conjunction with specific examples:

[0067] This embodiment defines a rule. In a communication system transmission scenario, configurations of phase tracking reference signals in different mapping modes can be selected; that is, during DFT-S-OFDM transmission, Pre-DFT phase tracking reference signals or Post-DFT phase tracking reference signals can be selected. DFT phase tracking reference signal or select these two reference signals to use simultaneously.

[0068] The rule can be to configure a signaling through which the above three selection methods of the phase tracking reference signal can be notified, and both Pre-DFT and Post-DFT PTRS can be used as the default configuration. This signaling can be a high-level signaling or physical layer signaling;

[0069] The rule can be to use the DFT points (or the density of Post-DFT PTRS) and ...

Description

technical field [0001] The present invention relates to the communication field, in particular, to a reference signal configuration method and device. Background technique [0002] In the high frequency band, the uplink single-carrier transmission technology is also affected by phase noise, and with the improvement of the modulation and demodulation level, the influence of phase noise is more serious. Currently, the uplink single-carrier is an orthogonal method of discrete Fourier transform spread spectrum. Frequency division multiple access technology scheme (Discrete-Fourier-transform spread optical Orthogonal Frequency Division Multiplexed, DFT-S-OFDM). Two methods for adding a phase tracking reference signal in uplink single carrier transmission are proposed in the related art. [0003] The first is to add a phase tracking reference signal to the data sample before the discrete Fourier transform module, the data and the phase tracking reference signal are simultaneously...
