Description

Reference signal transmission method and transmission device

technical field

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

Background technique

For the future-oriented fifth generation (5Generation, 5G) mobile communication system, in order to achieve the target of a downlink transmission rate of 20 Gbps and an uplink transmission rate of 10 Gbps, high-frequency transmission technology and large-scale antenna array technology have attracted much attention.

The high-frequency band has more abundant spectrum resources, but the transmission distance is limited due to the large attenuation; while the large-scale antenna array can provide a large beamforming gain, the antenna aperture is usually large. However, the two can be combined: the short-wavelength characteristics of high-frequency bands will reduce the aperture of large-scale antenna arrays, making the dense deployment of antennas easier and more feasible; conversely, the large beamforming gain generated by large-scale antenna arrays can Effectively fight against high-frequency transmission loss, thereby greatly extending the transmission distance of high-frequency transmission. Therefore, high-frequency transmission technology and large-scale antenna array technology complement each other, and the combination of the two can achieve complementary advantages.

Usually, in order to improve the effectiveness of transmission, high-order modulation, such as 16 quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM for short), 64QAM, 256QAM, is often used. However, higher-order modulations tend to be susceptible to phase noise. Also, the higher the modulation order, the more sensitive it is to phase noise. Further, the higher the operating frequency, the greater the phase noise. Therefore, for high-frequency transmission, in order to remove phase noise, the sender needs to send a reference signal known to the receiver, that is, the phase tracking reference signal (PTRS), and the receiver can estimate the phase noise based on it and then Perform the corresponding phase compensation. Usually, the frequency domain density of PTRS depends on the system bandwidth, for example, one PTRS subcarrier may be inserted every 1, every 2, every 4, every 8, or every 16 resource blocks (physical resource blocks, PRBs for short); The time-domain density is related to the modulation coding scheme (MCS) of the data symbols, for example, every 1, every 2, or every 4 orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols or SC - OFDM (single carrier OFDM) symbol inserts one PTRS symbol.

On the one hand, since the DMRS ports in a demodulation reference signal (demodulation reference signal, DMRS for short) port group are quasi-co-located (QCL for short), the phase noises of the corresponding data streams are the same , so a DMRS port group can share a PTRS port. Generally, the PTRS may be sent on a certain DMRS port in the DMRS port group.

On the other hand, a channel state information reference signal (CSI-RS for short) and a sounding reference signal (SRS for short) can be used for downlink and uplink channel state information (channel state information), respectively. information, CSI for short) acquisition and beam management.

Taking PTRS and CSI-RS as an example, since they have different functions, their pilot patterns are also different. If the two are configured independently, they will not be coordinated. Resource collisions usually occur.

When the reference signals collide with each other, one of them is usually punched. But this comes at the expense of performance. Taking the collision of PTRS and CSI-RS as an example, if the CSI-RS is punctured, it will inevitably affect the CSI measurement or beam management of a group of users; if the PTRS is punctured, the phase on all subcarriers on the OFDM symbol will be affected. The noise cannot be estimated, which affects the detection performance, especially when high-order modulation methods are used, the reliability of the communication link will be significantly reduced.

It can be seen from the above that, when the reference signals collide with each other, punching a certain reference signal that has collided cannot realize the function of the reference signal and affect the communication performance.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, detailed description will be given below in conjunction with specific embodiments and accompanying drawings.

The embodiments of the present invention aim at the problem that when two reference signals collide with resources, a certain reference signal that has collided is usually punctured, so that the function of the reference signal cannot be realized and the communication performance is affected. The embodiments of the present invention provide A reference signal transmission method and transmission device are provided, which avoid resource collision when the first preset reference signal and the second preset reference signal are transmitted, thereby improving the performance of each reference signal and effectively ensuring the reliability of the communication link.

As shown in FIG. 1 , a reference signal transmission method according to an embodiment of the present invention is applied to a transmitting end, and the transmission method includes:

Step 101: When the resource positions of the transmitted two preset reference signals meet the preset resource collision condition, perform a movement process on the subcarrier position of the first preset reference signal in the two preset reference signals, and obtain the The target subcarrier position of the first preset reference signal; wherein, the target subcarrier position is the frequency domain corresponding to the subcarrier of the second preset reference signal divided by the target physical resource block PRB where the first preset reference signal is located A frequency domain position other than the position, the second preset reference signal is a reference signal among the two preset reference signals.

The preset resource collision condition here may specifically be that subcarriers occupied by two preset reference signals overlap, and the first preset reference signal and the second preset reference signal may be PTRS and CSI-RS, respectively.

The above-mentioned target subcarrier position includes a subcarrier position of the target reference signal in a preset PRB of a preset PRB unit; wherein, the preset PRB unit includes at least one PRB. If the preset PRB unit includes 4 PRBs, the above-mentioned target resource positions may specifically be the subcarrier positions in the second PRB and the fourth PRB in the preset PRB unit.

In the method for transmitting a reference signal according to the embodiment of the present invention, when the resource positions of the two preset reference signals to be transmitted meet the preset resource collision condition, the sub-carrier position of any one of the preset reference signals is moved, thereby avoiding the need for The transmission resources of the two preset reference signals collide, which effectively improves the performance of each reference signal.
