Description

Technical Field

The present invention relates to the field of mobile communications technologies, and in particular, to a signal transmission method and apparatus, a terminal, and a network side device.

Background

In the field of wireless communication technology, phase noise comes from local oscillators in a transmitter and a receiver, which affect transmission of multicarrier signals, especially in a high frequency band (frequency band above 6 GHz), the effect of the phase noise is more serious, so that a receiving end needs to compensate the phase noise of a received signal to ensure system performance. In particular, the effect of phase noise on the data signal is mainly twofold: one is a common phase noise error (Common Phase Error, CPE), one common phase rotation error for each subcarrier; second, inter-subcarrier interference (ICI). With increasing radio frequency frequencies, such as the 52.6GHz (gigahertz) to 70GHz band, the impact of phase noise on the modulation and coding strategy (Modulation and Coding Scheme, MCS) level becomes more and more pronounced.

In The prior art, in The third generation partnership project (The 3rd Generation Partnership Project,3GPP) standard protocol, regarding transmission of a Phase noise tracking reference signal (Phase-tracking Reference Signal, PTRS) in a frequency domain, only a transmission mode of comb (or grid-like) transmission resources is defined, and a transmission mode of block-like transmission resources is not defined. It is therefore desirable to provide a transmission scheme for phase noise tracking reference signals in block transmission resources.

Referring to fig. 1, fig. 1 shows a flowchart of a signal transmission method provided in an embodiment of the present application, where the method is applied to a network side device, and the method includes:

step 101, determining resource parameters of continuous transmission resources to be transmitted; the resource parameters comprise intermediate resource parameters, guard interval resource parameters, time domain density parameters and subcarrier position parameters of frequency domain resources of a target Orthogonal Frequency Division Multiplexing (OFDM) symbol; the subcarrier position parameters of the frequency domain resource comprise intermediate subcarrier position parameters and guard interval subcarrier position parameters; and the intermediate subcarrier position parameter and the guard interval subcarrier position parameter are determined according to the intermediate resource parameter and the guard interval resource parameter.

In contrast to the comb transmission resource, the continuous transmission resource in the embodiment of the present application is a block transmission resource. The intermediate resource parameter is used for indicating the number of continuous subcarriers of the intermediate resource, the intermediate subcarrier position parameter is used for indicating the frequency domain position of the continuous subcarriers of the intermediate resource, and the continuous subcarriers of the intermediate resource are used for transmitting the phase tracking reference signal. The guard interval resource parameter is used for indicating the number of reserved continuous subcarriers of the guard interval resource, the guard interval subcarrier position parameter is used for indicating the frequency domain position of the reserved continuous subcarriers of the guard interval resource, and null signals are transmitted at the reserved continuous subcarrier positions.

As a first example, as shown in fig. 2, where the block-shaped continuous transmission resources include guard interval resources and intermediate resources, the guard interval resources include an upper guard interval resource and a lower guard interval resource.

102, determining a target OFDM symbol; wherein there is one target OFDM symbol per each interval of the time domain density parameter number OFDM symbols in the time domain.

In the time domain, there is one target OFDM symbol for transmitting the continuous transmission resource every interval of the time domain density parameter l_ptrs OFDM symbols.

Step 103, in a phase noise tracking reference signal PTRS port associated with a demodulation reference signal DMRS port of the target OFDM symbol, transmitting a phase tracking reference signal to a terminal at a position indicated by the intermediate subcarrier position parameter, and transmitting a null value to the terminal at a position indicated by the guard interval subcarrier position parameter.

After determining the target OFDM symbol, transmitting PTRS in the target OFDM symbol; in the transmission process, in a PTRS port associated with a demodulation reference signal (DMRS) port of a target OFDM symbol, transmitting the PTRS at an intermediate subcarrier position (intermediate resource in fig. 2); and transmitting null values to the terminal at positions indicated by the guard interval subcarrier position parameters (upper guard interval resources, lower guard interval resources in fig. 2), and using the transmitted null value signals as guard interval resources of the PTRS.

Furthermore, the applicant has found that in the prior art, PTRS only considers eliminating the effect of CPE on the data signal and does not consider eliminating the effect of ICI on the data signal in the transmission mode of comb transmission resources (i.e. discontinuous transmission resources). However, it is not enough to eliminate only the effect of CPE on the data signal, and as the carrier frequency gets higher, it becomes more important to eliminate the effect of ICI on the data signal. If the ICI between each subcarrier in the frequency domain needs to be eliminated, a block transmission resource needs to be configured for the PTRS in the frequency domain, the PTRS is transmitted by using the configured block transmission resource, and the PTRS is received at the receiving end and phase noise estimation is performed, so that the estimated phase noise can eliminate the influence of CPE and also eliminate the influence of ICI. Therefore, in the embodiment of the present application, by configuring the transmission mode of PTRS in the block transmission resource (i.e. the continuous transmission resource), ICI caused by phase noise is effectively eliminated.

In the embodiment of the application, the resource parameter of the continuous transmission resource to be transmitted is determined; the resource parameters comprise intermediate resource parameters, guard interval resource parameters, time domain density parameters and subcarrier position parameters of frequency domain resources of a target Orthogonal Frequency Division Multiplexing (OFDM) symbol; determining a target OFDM symbol; and in a phase noise tracking reference signal PTRS port associated with a demodulation reference signal DMRS port of the target OFDM symbol, transmitting a phase tracking reference signal to a terminal at a position indicated by the intermediate subcarrier position parameter, and transmitting a null value to the terminal at a position indicated by the guard interval subcarrier position parameter, so that the PTRS is transmitted in a block transmission resource.

In an alternative embodiment, before determining the resource parameter of the continuous transmission resource to be transmitted, the method includes:

configuring the resource parameters for the continuous transmission resources; the network side equipment configures the transmission parameters for the terminal; after the resource parameter is configured, the network side device can transmit the continuous transmission resource to the terminal by using the resource parameter, and the terminal can also transmit the continuous transmission resource to the network side device according to the resource parameter.

The step of allocating the resource parameters for the continuous transmission resource includes the following steps, and it should be noted that the execution sequence of the steps is not different.

The first step, the intermediate resource parameter and the guard interval resource parameter of the continuous transmission resource are configured; the intermediate resource parameter is used for indicating the number of continuous subcarriers of the intermediate resource, and the intermediate resource is used for tracking reference signals by phase; the guard interval resource parameter is used to indicate a frequency domain position of reserved continuous subcarriers of the guard interval resource, and null signals are transmitted at the reserved continuous subcarrier positions.

Step two, determining a preset time domain density parameter of the continuous transmission resource; the time-domain density parameter may be preset to a default value, or may be determined according to other parameters, for example, determined according to the MCS size.

And thirdly, determining the subcarrier position parameter of the frequency domain resource of the target OFDM symbol according to the intermediate resource parameter and the guard interval resource parameter. The subcarrier position parameters of the frequency domain resource comprise intermediate subcarrier position parameters and guard interval subcarrier position parameters; and the intermediate subcarrier position parameter and the guard interval subcarrier position parameter are determined according to the intermediate resource parameter and the guard interval resource parameter.

In an alternative embodiment, the first step includes:

determining an initial intermediate resource parameter and an initial guard interval resource parameter of the continuous transmission resource; for example, the network side device respectively presets an initial intermediate resource parameter and an initial guard interval resource parameter, or the initial intermediate resource parameter and the initial guard interval resource parameter are configured in a radio resource control layer (Radio Resource Control, RRC) signaling;

if the minimum number of resource blocks is less than or equal to the number of resource blocks, the intermediate resource parameter is the initial intermediate resource parameter, and the guard interval resource parameter is the initial guard interval resource parameter; for example, if the initial intermediate resource parameter is N0 _P ^B _T ^W _RS The initial guard interval resource parameter is N0 _P ^Re _T ^s _R ^e _S ^rved The minimum resource block number determined according to the two is smaller than or equal to the resource block number, the intermediate resource parameter N _P ^B _T ^W _RS ＝N0 _P ^B _T ^W _RS Guard interval resource parameter N _P ^R _T ^e _R ^se _S ^rved ＝N0 _P ^Re _T ^s _R ^e _S ^rved 。

Otherwise, respectively performing M-reduction processing on the initial intermediate resource parameter and the initial guard interval resource parameter to obtain a current intermediate resource parameter and a current guard interval resource parameter after the M-reduction processing, and continuously judging whether the current intermediate resource parameter and the current guard interval resource parameter meet the minimum resource block number or not is smaller than or equal to the resource block number; wherein M is a positive integer greater than zero; circularly processing until the current intermediate resource parameter and the current guard interval resource parameter which meet that the minimum resource block number is smaller than or equal to the resource block number are obtained; the current intermediate resource parameter is the intermediate resource parameter, and the current guard interval resource parameter is the guard interval resource parameter.

Specifically, if the minimum number of resource blocks is less than or equal to the number of resource blocks, the network side device performs M subtracting processing on the intermediate resource parameter as the initial intermediate resource parameter, calculates the minimum number of resource blocks at the moment to be less than or equal to the number of resource blocks, and continuously judges whether the minimum number of resource blocks at the moment is less than or equal to the number of resource blocks or not: if the minimum resource block number is smaller than or equal to the resource block number at the moment, the current intermediate resource parameter is the intermediate resource parameter, and the current guard interval resource parameter is the guard interval resource parameter; otherwise, the M-subtracting processing … … is continuously performed on the current intermediate resource parameter and the current guard interval resource parameter, and the intermediate resource parameter and the guard interval resource parameter which meet the minimum number of resource blocks being less than or equal to the number of resource blocks are obtained. It can be appreciated that the M subtracting process is to subtract the values of the current intermediate resource parameter and the current guard interval resource parameter by the value M respectively, so as to reduce the number of corresponding continuous subcarriers.

In an optional embodiment, the determining the number of resource blocks and the minimum number of resource blocks of the continuous transmission resource according to the initial intermediate resource parameter and the initial guard interval resource parameter includes:
