Description

Transmission method of reference signal, base station and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a base station, and a terminal for transmitting a reference signal.
Background
For the fifth Generation (5Generation, abbreviated as 5G) mobile communication system in the future, high frequency transmission technology and large scale antenna array technology are attracting attention in order to achieve the objectives of 20Gbps for downlink transmission rate and 10Gbps for uplink transmission rate.
The high-frequency band has richer spectrum resources, but the transmission distance is limited due to large attenuation; while large-scale antenna arrays can provide larger beamforming gain, the antenna aperture is usually larger. However, the two may be combined: the short wavelength characteristic of the high frequency band can reduce the aperture of the large-scale antenna array, so that the dense deployment of the antenna is easier and more feasible; on the contrary, the large beam forming gain generated by the large-scale antenna array can effectively resist the high-frequency transmission loss, thereby greatly expanding the transmission distance of high-frequency transmission. Therefore, the high-frequency transmission technology and the large-scale antenna array technology complement each other, and the combination of the high-frequency transmission technology and the large-scale antenna array technology can achieve complementary advantages.
Generally, in order to improve the transmission efficiency, high-order Modulation such as 16 Quadrature Amplitude Modulation (QAM), 64QAM, 256QAM is often used. However, higher order modulation is often susceptible to phase noise. Also, the higher the modulation order, the more sensitive 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 transmitting end needs to transmit a reference signal known to the receiving end, i.e. a Phase Tracking Reference Signal (PTRS), according to which the receiving end can estimate the phase noise and then perform corresponding phase compensation. Generally, the frequency-domain density of PTRS depends on the system bandwidth, and for example, one PTRS subcarrier may be inserted every 1, every 2, every 4, every 8, or every 16 resource blocks (PRBs); the time domain density is related to a Modulation Coding Scheme (MCS) of the data symbols, and for example, one PTRS symbol may be inserted every 1, 2, or 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols or SC-OFDM (single carrier OFDM) symbols.
On one hand, since DMRS ports in a demodulation reference signal (DMRS) port group are quasi-co-located (QCL), and phase noise of corresponding data streams is the same, one DMRS port group may share one PTRS port. In general, the PTRS may be transmitted on one of the DMRS ports in the group of DMRS ports.
On the other hand, a channel state information reference signal (CSI-RS) and a Sounding Reference Signal (SRS) may be used for Channel State Information (CSI) acquisition and beam management of a downlink and an uplink, respectively.
Taking PTRS and CSI-RS as examples, the pilot patterns are different for the PTRS and CSI-RS due to their different roles. If the two are configured independently, no coordination is performed. Resource collisions typically occur.
When the reference signals collide with each other, one of them is usually punctured. But this comes at the expense of performance. Taking the collision of the PTRS and the CSI-RS as an example, if the CSI-RS is punctured, it is inevitable to affect CSI measurement or beam management of a group of users; if the PTRS is punctured, the phase noise on all subcarriers of the OFDM symbol cannot be estimated, which affects the detection performance, and especially in the case of adopting a high-order modulation method, the reliability of the communication link is significantly reduced.
As can be seen from the above, when the reference signals collide with each other, the communication performance is affected by puncturing a reference signal that has collided with the reference signal.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.
The invention provides a transmission method of reference signals, aiming at the problem that when the reference signals collide with each other, the collision of a certain reference signal is punched, the action of the reference signal cannot be realized, and the communication performance is influenced.
As shown in fig. 1, an embodiment of the present invention provides a method for transmitting a reference signal, which is applied to a base station, and includes:
step 101: n or N-1 target reference signals are selected from N preset reference signals, wherein N is a positive integer greater than or equal to 2.
The N preset reference signals are N reference signals which are possible to generate resource collision, and N or N-1 target reference signals to be subjected to frequency hopping processing are selected from the N preset reference signals, so that the probability of resource collision is reduced. The N preset reference signals may be specifically at least two of CSI-RS, SRS, PTRS, and DMRS.
For example, when N is equal to 2, the two preset reference signals may be specifically CSI-RS and PTRS, or SRS and PTRS, and any one of the two preset reference signals or the two preset reference signals may be used as the target reference signal.
Step 102: and carrying out frequency hopping processing on the resource position of each target reference signal in a preset frequency hopping range through a preset function to obtain the target resource position of each target reference signal.
The target resource position comprises a subcarrier resource position of the target reference signal in a preset PRB of a preset PRB unit; wherein the preset PRB unit comprises at least one PRB. The predetermined PRB unit includes 4 PRBs, and the target resource location may be a subcarrier resource location in a second PRB and a fourth PRB of the predetermined PRB unit.
The preset function can be specifically a preset random function agreed in advance by a protocol, and the target resource position of each target reference signal is obtained by processing through the preset random function, so that the target resource position of each target reference signal has randomness, the probability of collision of the resource positions of the reference signals is reduced, and the performance of each reference signal is further improved.
Further, the preset frequency hopping range includes a first frequency hopping range, a second frequency hopping range, or a third frequency hopping range.
The first frequency hopping range is a frequency domain set of frequency domains corresponding to all subcarriers in a physical resource block PRB where a current target reference signal is located;
the second frequency hopping range is a set of frequency domains corresponding to subcarriers except for a first reference signal in the frequency domain set, and the first reference signal is a reference signal except for a current target reference signal in the N preset reference signals;
the third frequency hopping range is a set of frequency domains corresponding to subcarriers of a second reference signal in the set of frequency domains, and the second reference signal is a reference signal different from the N preset reference signals.
Assuming that the N preset reference signals include a CSI-RS and a PTRS, and the current target reference signal is the PTRS, the first frequency hopping range is a frequency domain set of frequency domains corresponding to all subcarriers in a PRB where the PTRS is located; the second frequency hopping range is a set of frequency domains corresponding to subcarriers occupied by the CSI-RS in the PRB where the PTRS is located; the third frequency hopping range may be specifically a set of frequency domains corresponding to subcarriers occupied by DMRSs in a PRB in which the PTRS is located.
Since DMRS ports in one demodulation reference signal port group are quasi-co-located (QCL), and phase noise of corresponding data streams is the same, one DMRS port group may share one PTRS port. In general, the PTRS may be transmitted on one of the DMRS ports in the group of DMRS ports.
Step 103: and transmitting the target reference signal with the terminal at the target resource position.
The transmission includes uplink transmission and downlink transmission, in the downlink transmission, the base station sends the target reference signal to the terminal at the target resource position, and in the uplink transmission, the base station receives the target reference signal sent by the terminal at the target resource position.
According to the transmission method of the reference signal, the resource position of the target reference signal is subjected to frequency hopping processing, the resource position occupied by each target reference signal is randomized, and then the target reference signal is transmitted at the target resource position, so that the probability of collision of the resources of the reference signal is reduced, the performance of each reference signal is improved, and the reliability of a communication link is effectively guaranteed. Further, before the step 103, the method further includes:
and indicating the preset parameters of the preset function to the terminal in an implicit or explicit mode.
In this case, the step 103 may specifically include:
and receiving a target reference signal sent by the terminal on the target resource position according to the preset function and the preset parameter.
The target reference signal (such as PTRS) of the embodiments of the present invention may be transmitted on the downlink or may be transmitted on the uplink. When transmitting on the downlink, the base station performs frequency hopping on the resource position of the target reference signal according to a preset function, and explicitly or implicitly notifies the terminal of the preset parameter of the preset function by the base station. The base station sends a target reference signal at a target resource position, and the terminal determines the target resource position according to a preset function and preset parameters indicated by the base station and receives the target reference signal sent by the base station at the target resource position. When the transmission is performed on the uplink, that is, the PTRS is sent from the terminal to the base station, at this time, the base station notifies the preset parameters of the preset function to the terminal in an explicit or implicit manner. The terminal determines a target resource position according to the preset function and the preset parameters notified by the base station, and transmits a target reference signal at the target resource position, and the base station determines the target resource position according to the preset function and receives the target reference signal transmitted by the terminal at the target resource position.
Further, the step of indicating the preset parameter of the preset function to the terminal in an explicit manner includes:
indicating the preset parameters of the preset function to the terminal through a preset message;
wherein the preset message comprises: at least one of physical layer signaling, media access control, MAC, layer signaling, and radio resource control, RRC, higher layer signaling.
Further, the step of indicating the preset function to the terminal in an implicit manner includes:
and indicating the preset parameters of the preset function to the terminal through protocol agreement.
It should be noted that the preset parameter may specifically include at least one of a terminal device identifier, a serving cell identifier of the terminal, an index of a PRB where the current target reference signal is located, an index of a subband where the current target reference signal is located, an index of a timeslot where the current target reference signal is located, and an index of a micro timeslot where the current target reference signal is located.
In the embodiment of the invention, the preset parameters of the preset function are indicated to the terminal, so that the terminal determines the target resource position of the target reference signal according to the preset function and the preset parameters, and receives the target reference signal sent by the base station at the target resource position or sends the target reference signal to the base station at the target resource position.
A specific application of the embodiments of the present invention is described below.
The N preset reference signals comprise two reference signals, namely CSI-RS and PTRS, wherein the PTRS corresponds to one DMRS port group and is transmitted on one DMRS port. And performing frequency hopping processing on the resource position of the PTRS in all subcarriers of the PRB where the PTRS is located, namely the PTRS occupies different subcarrier positions in different PRBs. As shown in fig. 2, the frequency hopping process can be expressed as a mapping function as follows:
isubcarrier＝fPTRS(iPRB，s)；
wherein f isPTRSRepresenting a predetermined function, isubcarrierDenotes the subcarrier index, i, of PTRS within PRBPRBDenotes the index of the PRB where the PTRS is located, s denotes the parameter of the preset function, s may be specifically a parameter or a vector (including multiple parameters), when f isPTRSIn the case of a random function (random number generator), s is a vector containing the seed of the random number generator.
As shown in fig. 2, the PTRS has different positions in the two PRBs and has no resource collision with the CSI-RS, and the PTRS is subjected to frequency hopping, so that the probability of resource collision between the PTRS and the CSI-RS is reduced, and the reliability of the communication link is effectively improved.
Another specific application of the embodiments of the present invention is described below.

And carrying out frequency hopping processing on the resource position of the PTRS in the subcarrier where the DMRS port in the PRB where the PTRS is located, namely the PTRS occupies different DMRS subcarrier positions in different PRBs. As shown in fig. 3, the frequency hopping process can be expressed as a mapping function as follows:
isubcarrier＝gPTRS(iPRB，s)；
wherein, gPTRSRepresenting a predetermined function, isubcarrierDenotes the sub-carrier index of PTRS in PRB (corresponding to the sub-carrier occupied by DMRS port), iPRBDenotes the index of the PRB where the PTRS is located, s denotes the parameter of the preset function, s may be specifically a parameter or a vector (including multiple parameters), when gPTRSIn the case of a random function (random number generator), s is a vector containing the seed of the random number generator.
As shown in fig. 3, in the sub-carrier where the DMRS port in the PRB where the PTRS is located, the PTRS is subjected to frequency hopping, so that the PTRS occupies different DMRS sub-carrier positions in each PRB where the PTRS is located, and the probability of resource collision with the CSI-RS is reduced, thereby effectively improving the performance of each reference signal and effectively ensuring the reliability of a communication link.
According to the transmission method of the reference signal, N or N-1 target reference signals are selected from N preset reference signals, frequency hopping processing is carried out on the resource position of each target reference signal within a preset frequency hopping range through a preset function, and the resource position occupied by each target reference signal is randomized, so that the probability of collision of the resources of the reference signals is reduced, the performance of each reference signal is improved, and the reliability of a communication link is effectively guaranteed.
As shown in fig. 4, an embodiment of the present invention further provides a method for transmitting a reference signal, which is applied to a terminal, and includes:
step 401: according to preset parameters of a preset function indicated by a base station, carrying out frequency hopping processing on a resource position of a target reference signal in a preset frequency hopping range to obtain a target resource position of the target reference signal, wherein the target reference signal is one reference signal in N preset reference signals;
the N preset reference signals are N reference signals which may cause resource collision. The N preset reference signals may be specifically at least two of CSI-RS, SRS, PTRS, and DMRS.
The target resource position comprises a subcarrier resource position of the target reference signal in a preset PRB of a preset PRB unit; wherein the preset PRB unit comprises at least one PRB. The predetermined PRB unit includes 4 PRBs, and the target resource location may be a subcarrier resource location in a second PRB and a fourth PRB of the predetermined PRB unit.
The preset function can be specifically a preset random function agreed in advance by a protocol, and the target resource position of each target reference signal is obtained by processing through the preset random function, so that the target resource position of each target reference signal has randomness, the probability of collision of the resource positions of the reference signals is reduced, and the performance of each reference signal is further improved.
Further, the preset frequency hopping range includes a first frequency hopping range, a second frequency hopping range, or a third frequency hopping range.
The first frequency hopping range is a frequency domain set of frequency domains corresponding to all subcarriers in a physical resource block PRB where the target reference signal is located;

Since DMRS ports in one demodulation reference signal port group are quasi-co-located (QCL), and phase noise of corresponding data streams is the same, one DMRS port group may share one PTRS port. In general, the PTRS may be transmitted on one of the DMRS ports in the group of DMRS ports.
Step 402: and transmitting the target reference signal with the base station at the target resource position.
This step 402 specifically includes: receiving a target reference signal sent by the base station on the target resource position; or, the target reference signal is sent to the base station at the target resource position.
In the embodiment of the invention, the terminal determines the target resource position of the target reference signal according to the preset function and the preset parameter indicated by the base station, and receives the target reference signal sent by the base station at the target resource position or sends the target reference signal to the base station at the target resource position.
Further, before the step 401, the method further includes:
and acquiring preset parameters of a preset function indicated by the base station in an explicit or implicit mode.
Specifically, the step of obtaining the preset parameter of the preset function indicated by the base station in an explicit manner includes:

wherein the preset message comprises: at least one of physical layer signaling, media access control, MAC, layer signaling, and radio resource control, RRC, higher layer signaling.
Specifically, the step of obtaining the preset parameter of the preset function indicated by the base station in an implicit manner includes:
and acquiring preset parameters of a preset function indicated by the base station through protocol convention.
Here, the base station and the terminal use the same preset function and preset parameters to determine the target resource location of the target reference signal, so that the base station and the terminal can accurately transmit and receive the target reference signal at the target resource location.
According to the transmission method of the reference signal, the resource position of the target reference signal is subjected to frequency hopping processing within a preset frequency hopping range according to the preset parameter of the preset function indicated by the base station, and the target resource position of the target reference signal is obtained; and transmitting the target reference signal with the base station at the target resource position. Because the positions of the resources occupied by the target reference signals are randomized, the probability of collision of the resources of the reference signals is reduced, the performance of each reference signal is improved, and the reliability of a communication link is effectively guaranteed.
