Description

Parameter configuration method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a parameter configuration method and device.

Background

Multiple Input Multiple Output (MIMO) systems typically use precoding techniques to improve the channel, so as to improve the spatial multiplexing (spatial multiplexing) effect. The precoding technology uses a precoding matrix matched with a channel to process a spatially multiplexed data stream (hereinafter referred to as a spatial stream for short), thereby implementing precoding on the channel and improving the reception quality of the spatial stream.

The precoding techniques include linear precoding techniques and nonlinear precoding techniques. The nonlinear precoding technology can be considered as introducing a nonlinear processing link on the basis of the linear precoding technology. During the non-linear processing of the signal, the transmission power of the signal may change, which may cause the actual transmission power to exceed the allowable transmission power limit of the system. Therefore, power adjustment of the signal is required so that the actual transmit power does not exceed the transmit power limit allowed by the system.

Power adjustment may be achieved by modulo (modulo) operation. At present, when the modulation order of the modulation mode of a signal is fixed, the value of the boundary (VRB) of the modulo operation is fixed, which cannot meet the flexibility requirement of the system, thereby reducing the overall performance of the system. The VRB value is used to indicate the modulus value of the modulo operation.

Detailed Description

The nonlinear processing element of the nonlinear precoding technology comprises a power adjustment operation and a filtering operation. The power adjustment operation is used to adjust the power of the signal to be transmitted. The filtering operation is used to pre-cancel interference generated by the signal to be transmitted via the channel. The signal to be transmitted comprises one or more symbols to be transmitted. The symbol to be transmitted refers to a constellation symbol (or modulation symbol) obtained by constellation mapping (i.e., modulation) of a coded bit (or a coded bit stream). In the embodiments of the present application, the signal to be transmitted generally refers to a data signal. The following description will be made by taking an example of performing the power adjustment operation and the filtering operation on the symbol to be transmitted.

The non-linear precoding technique applicable to the embodiments of the present application is not limited in the embodiments of the present application, and for example, the non-linear precoding technique may include: Tomlinson-Harashima precoding (THP), vector perturbation precoding (vector perturbation precoding), dirty paper precoding (dirty paper precoding), and the like. In some descriptions below, the non-linear precoding technique is exemplified as THP.

Fig. 1 shows a schematic diagram of a THP process. S in fig. 1 represents a constellation symbol obtained by constellation mapping of coded bits, and may also be referred to as an original symbol to be transmitted. x represents a symbol obtained by nonlinear processing of the symbol s. y denotes the sign of the symbol x after the filtering operation, and z denotes the sign of the symbol s minus the symbol y.

Assume that one Resource Element (RE) carries 4 symbols, respectively denoted as s₁～s₄And the 4 symbols are symbols mapped to different transmission layers or symbols mapped to different antenna ports, respectively, and the 4 symbols are described as symbols mapped to different transmission layers in the following; then, the 4 symbols after nonlinear processing can be expressed as the following formula 1:

equation 1:

wherein s is_iIndicating symbols to be transmitted (i.e., symbols on the ith transport layer) mapped to the ith transport layer. x is the number of_iRepresents a pair symbol s_iThe resulting symbols are subjected to a non-linear processing. I is not less than 1 and not more than 4, i is an integer.

Representing a coefficient matrix used in performing the filtering operation. l_abAnd the channel coefficient between the a-th receiving antenna port of the terminal and the b-th sending antenna port of the network equipment is represented, a is more than or equal to 1 and less than or equal to 4, b is more than or equal to 1 and less than or equal to 4, and a and b are integers.

As can be seen from equation 1, after the nonlinear processing, the symbols on the ith transmission layer are superimposed with the interference generated by the symbols on the 1 st and 2 … i-1 st transmission layers, and therefore, after the nonlinear processing, the transmission power of the symbols to be transmitted changes compared with that before the nonlinear processing, which may cause the transmission power of the symbols to be transmitted after the nonlinear processing to exceed the allowable transmission power limit of the system.

Taking the QPSK modulation symbol as an example,

b (2i) and b (2i +1) may each take any of values 00, 01, 10 and 11, s_iThe position in the constellation plane may be one of the positions where the four vertices of a rectangle, as shown by the solid lines in fig. 2, are located, typically, the rectangle is a square, and the center of the square is the origin of coordinates. In fig. 2, the horizontal axis represents the real axis and the vertical axis represents the imaginary axis.

As can be seen from fig. 1, s-y ═ z. As can be seen from fig. 2, the position of s in the constellation plane may be one of the positions of the four vertices of the rectangle shown by the solid line in fig. 2, and the position of z in the constellation plane is outside the rectangle shown by the solid line in fig. 2. In order to limit the transmission power of the symbols to be transmitted after the nonlinear processing within the transmission power allowed by the system, the power adjustment operation in the nonlinear processing element can be implemented. Performing a power adjustment operation on a symbol to be transmitted may include: and moving the symbol to be sent. The shifting refers to translating the real part and/or the imaginary part of the symbol to be transmitted. For example, with reference to fig. 1, the symbol z may be shifted according to the following formula 2 to obtain the symbol x:

equation 2:

where a is the amount of movement of the symbol z, and a includes a real part and/or an imaginary part. Re (z) denotes the real part of a, and im (z) denotes the imaginary part of a. M is a modulation order. For example, if the modulation scheme is Quadrature Phase Shift Keying (QPSK), M is 2; if the modulation scheme is 16 quadrature amplitude modulation (16 QAM), M is 4.

The shifting of the symbol z in the above formula 2 is realized by modulo operation. Wherein the modulus values for the modulo operations for the real and imaginary parts are both 2M.

It will be appreciated that the absolute value of the result of the modulo operation is less than the absolute value of the modulo operation. For example, if the modulo operation is 8mod 3 — 2, the modulo value is 3. The result of the modulo operation is 2. Typically, the modulus value of the modulo operation is indicated using the modulo operation boundary (i.e., VRB).

VRB is the boundary value of the range of values of the result of the modulo operation on the real and/or imaginary axes. The VRB may include a VRB value in a horizontal direction and a VRB value in a vertical direction. For example, the VRB value in the horizontal direction may be the VRB value a and/or the VRB value C in fig. 2, and the VRB value in the vertical direction may be the VRB value B and/or the VRB value D in fig. 2.

For one modulo operation, the rectangular range defined based on 2VRB values in the horizontal direction and 2VRB values in the vertical direction is called the modulo operation boundary range. For example, the rectangles shown by the dashed boxes defined by the VRB value A, VRB value C, VRB value B and the VRB value D in FIG. 2 represent the modulo operation boundary ranges. It will be appreciated that the coordinate values of the result of the modulo operation lie within the boundaries of the modulo operation.

The constellation boundary range refers to a rectangular range defined by possible constellation symbols in a certain modulation mode. For example, if the modulation scheme is QPSK, the constellation boundary range may be as shown by the solid line box in fig. 2. The boundary value of the constellation boundary range is the constellation boundary value.

Based on the above formula 2, in the currently provided technical solution of the modulo operation, for any modulation order M, a fixed distance exists between the boundary value of the modulo operation (i.e. the VRB value) and the boundary value of the constellation, such as θ in fig. 2₁And theta₂Is a fixed value. This does not meet the flexibility requirements of the system, thereby reducing the overall performance of the system.

Therefore, the embodiment of the application provides a parameter configuration method and device, and particularly configures a VRB value through signaling.

Hereinafter, the technical solutions provided in the embodiments of the present application will be described with reference to the drawings.

Fig. 5 is an interaction diagram of a parameter configuration method according to an embodiment of the present application. The method shown in fig. 5 includes:

s101: the network equipment generates a parameter configuration signaling, wherein the parameter configuration signaling is used for configuring N VRB values, N is more than or equal to 1, and N is an integer; the N VRB values have corresponding relation with at least one of the following parameters of the signal to be transmitted: transport layer (i.e., spatial streams), antenna ports, codewords, modulation orders, and MCS.

The N VRB values have a corresponding relationship with at least one parameter, that is, the N VRB values are bound to the at least one parameter, so as to indicate that the N VRB values are set for the at least one parameter. The corresponding relationship may be represented by, for example, but not limited to, a list, a table, a formula, or the like, which is not limited in the embodiment of the present application.

The existence of a correspondence between the N VRB values and the at least one parameter may be predefined, as predefined by the protocol; the network device may also configure the terminal through signaling, and the signaling and the parameter configuration signaling in S101 may be the same signaling or different signaling. For example, the parameter configuration signaling in S101 may be DCI, and the signaling configuring the correspondence between the N VRB values and the at least one parameter may be RRC signaling. Of course, the embodiments of the present application are not limited thereto. Optionally, the network device receives indication information sent by the terminal, where the indication information is used to indicate a configuration mode of a correspondence between the N VRB values and the at least one parameter of the terminal, and the configuration mode includes signaling configuration or predefined. And the network equipment determines the configuration mode of the corresponding relation between the N VRB values and the at least one parameter according to the indication information. For example, the network device may configure the corresponding relationship to the terminal through the signaling when it is determined that the indication information is used to indicate that the terminal supports configuring the corresponding relationship in a signaling configuration manner; and when the indication information is determined to be used for indicating that the terminal supports the configuration of the corresponding relationship in the predefined mode, the corresponding relationship is not configured to the terminal through signaling.

In the specific implementation process, the corresponding relationship between the N VRB values and the at least one parameter can be directly set; the correspondence relationship between the N VRB values and the at least one parameter may also be set by setting the correspondence relationship between the M1 VRB values (or the M2 VRB values) and the at least one parameter, although the embodiment of the present application is not limited thereto. Among them, the explanation of the M1 VRB values and the M2 VRB values can be referred to below.

Any of the N VRB values may be an absolute VRB value. If the nth VRB value among the N VRB values is VRB_nN is not less than 1 and not more than N, N is an integer, vrb_nFor indicating that the modulo operation boundary range is any one of:

the first method comprises the following steps: the boundary range of the modulo operation in the real axis direction of the constellation plane is (-vrb)_n,vrb_n]Or [ -vrb_n,vrb_n) The range on the real axis is enclosed by the dashed line in fig. 2. Based on this, an embodiment of the present application may provide a power adjustment operation by modifying a modulus value 2M of the modulo operation for the real part in equation 2 to 2vrb_n。

Therefore, the mode value of the modulus operation on the imaginary part may be obtained by referring to the mode value of the modulus operation on the real part, or by referring to the prior art, which is not limited in the embodiments of the present application.

And the second method comprises the following steps: the boundary range of the modulo operation in the imaginary axis direction of the constellation plane is (-vrb)_n,vrb_n]Or [ -vrb_n,vrb_n) The extent of the dashed box on the imaginary axis is shown in fig. 2. Based on this, an embodiment of the present application may provide a power adjustment operation by modifying a modulus value 2M of the above equation 2 for the modulus operation of the imaginary part to 2vrb_n。

Therefore, the mode value of the modular operation for the real part may be obtained by referring to the mode value of the modular operation for the imaginary part, or by referring to the prior art, which is not limited in this embodiment of the present application.

And the third is that: the boundary range of the modulo operation in the real axis direction of the constellation plane is (-vrb)_n,vrb_n]Or [ -vrb_n,vrb_n) And the boundary range of the modulo operation in the imaginary axis direction is (-vrb)_n,vrb_n]Or [ -vrb_n,vrb_n). The extent on the real axis and the extent on the imaginary axis are shown by the dashed boxes in fig. 2. In this case, based on this, an embodiment of the present application may provide a power adjustment operation by modifying the modulus value 2M of the modulo operation for the real part and the imaginary part in the above formula 2 to 2vrb_n。

Any of the N VRB values may be a relative VRB value, such as a value relative to a constellation boundary value. For example, if the nth VRB value of the N VRB values is VRB_nN is 1. ltoreq. n.ltoreq.N, N is an integer, and then vrb_nThe following is used to illustrate the modulo operation boundary range. Wherein, b in any of the following_MRepresents constellation boundary values of order M, i.e., constellation boundary values where the modulation order is M.

The first method comprises the following steps: the boundary range of the modulo operation in the real axis direction of the constellation plane is (- (vrb)_n+b_M),(b_M+vrb_n)]Or [ - (vrb)_n+b_M),(b_M+vrb_n) θ in fig. 2), as in fig. 2₁The value of (a). Based on this, an embodiment of the present application may provide a power adjustment operation by modifying a modulus value 2M of the modulo operation for the real part in equation 2 to 2vrb_n+2b_M。

And the second method comprises the following steps: the boundary range of the modulo operation in the direction of the imaginary axis of the constellation plane is (- (vrb)_n+b_M),(b_M+vrb_n)]Or [ - (vrb)_n+b_M),(b_M+vrb_n) θ in fig. 2), as in fig. 2₂The value of (a). Based on this, an embodiment of the present application may provide a power adjustment operation by modifying a modulus value 2M of the above equation 2 for the modulus operation of the imaginary part to 2vrb_n+2b_M。

And the third is that: the boundary range of the modulo operation in the real axis direction of the constellation plane is (- (vrb)_n+b_M),(b_M+vrb_n)]Or [ - (vrb)_n+b_M),(b_M+vrb_n) And the modulo operation boundary in the imaginary axis direction is (- (vrb)_n+b_M),(b_M+vrb_n)]Or [ - (vrb)_n+b_M),(b_M+vrb_n)). E.g. theta in fig. 2₁Value of and theta₂The value of (a). Based on this, an embodiment of the present application may provide a power adjustment operation by modifying the modulus value 2M of the modulo operation for the real part and the imaginary part in the above formula 2 to 2vrb_n+2b_M。

In the specific implementation process, any value (e.g., all values) of the N VRB values is specifically an absolute VRB value or a relative VRB value, and a value range is which one of the absolute VRB value or the relative VRB value is, which may be predefined, e.g., predefined by a protocol; or may be configured through signaling. This is not limited in the embodiments of the present application.

Any two VRB values of the N VRB values may or may not be equal.

If the N VRB values are all equal, the parameter configuration signaling is used to configure the N VRB values, and may be implemented as: the parameter configuration signaling contains a VRB value.

If some of the N VRB values are equal, the parameter configuration signaling is used to configure the N VRB values, and may be implemented as: the parameter configuration signaling comprises a plurality of unequal VRB values and a parameter number corresponding to each VRB value. For example, assuming that N is 4, the 4 VRB values (denoted as VRB values 1 to 4, respectively) are 1, 2, and 3, respectively; the 4 VRB values have a mapping relationship with the antenna ports, and the antenna ports of the terminal are 1 to 4, the parameter configuration signaling may include: the VRB values are 1, 2, and 3, and the VRB values whose values are 1 are related to the antenna ports 1 and 2, the VRB value whose value is 2 is related to the antenna port 3, and the VRB value whose value is 3 is related to the antenna port 4.

Whether any two VRB values of the N VRB values are equal or not, the parameter configuration signaling for configuring the N VRB values may be implemented as: the parameter configuration signaling contains the N VRB values. Optionally, the sequence of the N VRB values in the parameter configuration signaling is related to the parameter number. For example, assuming that N is 4, the 4 VRB values are respectively labeled as VRB values 1-4, the 4 VRB values have a mapping relationship with the antenna ports, and the antenna ports of the terminal are 1-4, the parameter configuration signaling may include: the VRB values are 1-4, and the VRB values 1-4 correspond to the antenna ports 1-4 in sequence, that is, the VRB value 1 is a VRB value of the antenna port 1 and is used for performing power adjustment on a signal to be transmitted on the antenna port 1, and the VRB value 2 is a VRB value of the antenna port 2 and is used for performing power adjustment on a signal to be transmitted on the antenna port 2, and the like.

S102: the network equipment sends the parameter configuration signaling.

In a specific implementation process, the parameter configuration signaling may be implemented by one or more types of signaling, where the type of signaling may include, but is not limited to, at least one of a higher layer configuration signaling (e.g., RRC signaling), a semi-static configuration signaling (e.g., MAC signaling), and a dynamic configuration signaling (e.g., DCI). For example, the parameter configuration signaling may be implemented by one of the following:

mode 1: the parameter configuration signaling comprises RRC signaling, MAC signaling or DCI.

Mode 2: the parameter configuration signaling comprises RRC signaling and MAC signaling; alternatively, the parameter configuration signaling includes RRC signaling and DCI. The RRC signaling is used to configure M1 VRB values, for example, the RRC signaling may carry the M1 VRB values. MAC signaling or DCI is used to configure N VRB values selected from the M1 VRB values. The N1 VRB values are some or all of the M1 VRB values.

Optionally, RRC signaling may also be used to configure the index of the M1 VRB values. In this case, the DCI may carry the index of the above-described N1 VRB values. In order to configure the indexes of the M1 VRB values through RRC signaling, the RRC signaling may carry an index corresponding to each VRB value in the M1 VRB values; or, it may be predefined to set the indexes of the M1 VRB values according to the order of the M1 VRB values carried in the RRC signaling and the value of the M1, in this case, the indexes of the M1 VRB values may not be carried in the RRC signaling. For example, assuming that M1 is 8 and RRC signaling includes 8 VRB values, the indexes of the 8 VRB values set according to the predefined rule may be binary numbers 000-111 in sequence.

Based on mode 2, the bit width (bit width) of the MAC signaling or DCI can be related to the RRC signaling, such as the bit of the MAC signaling or DCI

In one implementation, mode 2 may be replaced with: the above M1 VRB values are predefined, and the parameter configuration signaling may be MAC signaling or DCI. The N VRB values are some or all of the M1 VRB values.

Mode 3: the parameter configuration signaling comprises RRC signaling, MAC signaling and DCI. Wherein the RRC signaling is used to configure M1 VRB values. The MAC signaling is used to configure M2 VRB values selected from the M1 VRB values. The M2 VRB values are some or all of the M1 VRB values. DCI is used to configure N VRB values selected from the M2 VRB values. The N1 VRB values are some or all of the M2 VRB values.

Optionally, RRC signaling may also be used to configure the index of the M1 VRB values. The manner of configuring M1 VRB values and the index of M1 VRB values by RRC signaling may be referred to as the above manner 2, and is not described herein again.

Based on this optional implementation, in one example, the MAC signaling may carry an index of the M2 VRB values. The DCI may carry the index of the above-mentioned N VRB values.

Based on this optional implementation, in another example, the M1 VRB values belong to multiple sets, and RRC signaling may also be used to configure the set to which each of the M1 VRB values belong. Optionally, the RRC signaling may also be used to configure an index of each set, for example, the RRC signaling may carry the index of each set; alternatively, the set of determination rules may be predefined. Based on this, MAC signaling may carry one or more sets of indices, configuring M2 VRB values. Further, the DCI may carry one or more sets of indices, thereby configuring N VRB values; alternatively, the DCI may carry an index of one or more VRB values, thereby configuring N VRB values.

For example, RRC signaling is used to configure: VRB values 1-8, indexes of the 8 VRB values, VRBs 1-3 belonging to set 1, VRBs 4-6 belonging to set 2, and VRBs 7-8 belonging to set 3; the MAC signaling carries indexes of sets 1-2, namely M2 VRB values configured by the MAC signaling are VRB values 1-6. Based on this, the DCI carries the index of set 1, that is, the N VRB values configured by the DCI are VRB values 1-3.

Optionally, the network device receives indication information sent by the terminal. The indication information is used for indicating whether the terminal supports the set to which each of the M1 VRB values belongs. The network appliance may perform this example if the indication information indicates support for the set to which each of the M1 VRB values belong.

Based on mode 3, the bit width (bit width) of the DCI can be related to MAC signaling, such as the bit of the DCI

In one implementation, mode 3 may be replaced with: the M1 VRB values are predefined and the parameter configuration signaling may be MAC signaling and DCI. The MAC signaling is used to configure M2 VRB values, the M2 VRB values being some or all of the M1 VRB values. The N VRB values are some or all of the M2 VRB values.

In the specific implementation process, for the same type of signaling, the parameter configuration signaling may be implemented by one or more pieces of signaling. For example, assuming that signaling for implementing parameter configuration signaling includes DCI, and N is 2, the parameter configuration signaling may configure 2VRB values through DCI1 and DCI2, where DCI1 is used to configure one of the 2VRB values, and DCI2 is used to configure the other of the two VRB values. For another example, assuming that the signaling for implementing the parameter configuration signaling includes RRC signaling, and M is 10, the parameter configuration signaling may configure 10 VRB values through RRC signaling 1 and RRC signaling 2, where RRC signaling 1 is used to configure one part of the 10 VRB values, and RRC signaling 2 configures another part of the 10 VRB values. The embodiments of the present application are not limited thereto.

As an example, for the network device, after performing S102, the signal to be transmitted may be subjected to nonlinear precoding according to the parameter configuration signaling, and the signal to be transmitted after the nonlinear precoding is transmitted.

S103: the terminal receives the parameter configuration signaling.

S104: and the terminal determines the N VRB values according to the parameter configuration signaling.

As an example, after S104 is executed, for the terminal, after the nonlinear precoded signal is received, the received signal may be equalized according to the reference signal, and the equalized signal is inversely shifted (i.e., inversely shifted) according to the N VRB values and the candidate symbol set, so as to obtain a symbol to be decoded corresponding to each symbol in the signal, and then each symbol to be decoded is decoded. The symbol to be decoded is selected from a set of candidate symbols. The set of candidate symbols comprises a plurality of candidate symbols (i.e. candidate constellation symbols). The set of candidate symbols may also be referred to as a set of constellations. For example, if the modulation scheme is QPSK, the candidate symbol set may be a set of candidate symbols represented by four vertices of a rectangular box shown by a solid line in fig. 2.

In a specific implementation process, performing inverse shift on the equalized signal according to the N VRB values may include: determining a module value of a real part and/or an imaginary part of a symbol in the equalized signal when module operation is executed according to the N VRB values, namely determining a moving unit of the network equipment for moving; and then, according to the shifting unit, carrying out reverse shifting on each symbol obtained by equalization once or multiple times, so that the shifted symbol is located in the range where the constellation diagram is located for the first time (for example, if the modulation mode is QPSK, the range can be the range shown by a solid line box in table 2), and then, taking the candidate symbol which is in the candidate symbol set and has the closest distance to the symbol after reverse shifting as the symbol to be decoded corresponding to the symbol.

Optionally, assuming that there is a correspondence between the N VRB values and the transport layers, the N VRB values may specifically be VRB values of the N transport layers, and the VRB values correspond to the transport layers one to one. That is, the VRB value may be transport layer granular. Subsequently, for the signal of any transmission layer, the terminal may reverse the signal of the transmission layer according to the VRB value of the transmission layer. For example, assuming that the number of transport layers of the terminal is 2, N may be equal to 2.

In the specific implementation process, the embodiments of the present application are not limited thereto. For example, the N VRB values may be the VRB values of N1 transport layers, N1 > N. For example, assuming that the transport layers of the terminal are transport layers 0 to 3 (i.e., N1 is 4), N may be equal to 2, where the VRB values for transport layers 0 to 1 are the same and the VRB values for transport layers 2 to 3 are the same.

Optionally, assuming that there is a correspondence between the N VRB values and the antenna ports, the N VRB values may specifically be VRB values of the N antenna ports, and the VRB values correspond to the antenna ports one to one. That is, the VRB value may be antenna port granular. Subsequently, for the signal of any antenna port, the terminal may reverse the signal of the antenna port according to the VRB value of the antenna port. The antenna port refers to an antenna port (antenna port) used for data transmission, for example, an antenna port (antenna port for PDSCH) used for Physical Downlink Shared Channel (PDSCH) transmission, a demodulation reference signal (DMRS) port, or the like. For example, assuming that the number of DMRS ports allocated to the terminal by the network device is 2, N may be equal to 2.

In the specific implementation process, the embodiments of the present application are not limited thereto. For example, the N VRB values may be the VRB values of N2 transport layers, N2 > N. For example, assuming that the antenna ports of the terminal are antenna ports 0 to 3 (i.e., N2 is 4), N may be equal to 2, where the VRB values for antenna ports 0 to 1 are the same and the VRB values for antenna ports 2 to 3 are the same.

Optionally, assuming that there is a correspondence between the N VRB values and the codewords, the N VRB values may specifically be VRB values of the N codewords, and the VRB values correspond to the codewords one to one. That is, the VRB values may be codeword granular. Of course, the embodiments of the present application are not limited thereto. Specific examples or alternatives thereof can be inferred by the above examples.

Optionally, assuming that there is a correspondence between the N VRB values and the modulation orders, the N VRB values may specifically be VRB values of the N modulation orders, and the VRB values correspond to the modulation orders one to one. That is, the VRB values may be modulation order granular. Of course, the embodiments of the present application are not limited thereto. Specific examples or alternatives thereof can be inferred by the above examples. The modulation order may be related to a modulation scheme, for example, if the modulation scheme is QPSK, the modulation order is 2; if the modulation scheme is 16QAM, the modulation order is 4. It should be noted that, in this alternative embodiment, although the modulation orders and the VRB values may be in a one-to-one correspondence, the VRB value corresponding to each modulation order may not be fixed. Therefore, compared with the technical scheme that each modulation order corresponds to a fixed VRB value in the prior art, the configuration flexibility can be improved, and the overall performance of the system is improved. For example, based on the technical solution provided in the embodiment of the present application, the network device may configure, through signaling, that the VRB value corresponding to the modulation order equal to 2 is 3 or 5 or another value; and based on the technical scheme provided by the prior art, the VRB value corresponding to the modulation order equal to 2 is a fixed value of 5, and the like.

Optionally, assuming that there is a correspondence between the N VRB values and the MCSs, the N VRB values may specifically be VRB values of the N MCSs, and the VRB values correspond to the MCSs one to one. That is, the VRB value may be MCS granular. Of course, the embodiments of the present application are not limited thereto. Specific examples or alternatives thereof can be inferred by the above examples.

In the parameter configuration method provided in the embodiment of the present application, the network device configures the VRB value to the terminal through the parameter configuration signaling, so that, compared with a technical scheme in the prior art in which a relationship between the VRB value and the modulation order is fixed and unchanged, the configuration flexibility can be improved by configuring the VRB value through the parameter configuration signaling, which is beneficial to meeting the flexibility requirement of the system. In addition, since the boundary of the modulo operation approaches the constellation boundary, e.g., θ in FIG. 2₁And/or theta₂When the value of (a) is reduced, the transmission power which needs to be additionally paid for by the modulo operation is reduced, but at the same time, the level of the detection signal-to-noise ratio of the signal to be transmitted after the modulo operation is reduced. When the modulo operation boundary is far from the constellation boundary, e.g. θ in FIG. 2₁And/or theta₂When the value of (a) is increased, the transmission power which needs to be additionally paid for by the modulo operation is increased, but at the same time, the level of the detection signal-to-noise ratio of the signal to be transmitted after the modulo operation is increased. Therefore, the technical scheme provided by the embodiment of the application is combined to flexibly set the VRB value, which is beneficial to balancing the transmission power which needs to be additionally paid due to the modulo operation and the detection signal-to-noise ratio level of the signal to be transmitted after the modulo operation, thereby improving the overall performance of the system.

Optionally, the parameter configuration signaling includes indication information, where the indication information is used to instruct the network device to perform nonlinear precoding or not to perform nonlinear precoding. The indication information may also be referred to as a non-linear precoding selection indication.

Further optionally, the indication information may be a VRB value, for example, one of the N VRB values, or one of the M1 VRB values or M2 VRB values.

As one example, when the VRB value is an absolute VRB value, and the absolute VRB value is equal to the constellation boundary value, the VRB value indicates that non-linear precoding is not performed. Based on this, when the VRB value is indicated by RRC signaling, MAC signaling, or DCI, it indicates that the network device does not employ the non-linear precoding technique to precode the signal to be transmitted, in other words, the precoding technique employed by the network device is a linear precoding technique. For example, when the at least one parameter includes a transmission layer and the DCI indicates that the absolute VRB value is equal to the constellation boundary value, the network device may precode the signal to be transmitted of each transmission layer by using a linear precoding technique, or the network device may precode the signal to be transmitted of the transmission layer or each transmission layer corresponding to the absolute VRB value by using a linear precoding technique. Other examples are not listed.

As one example, when the VRB value is a relative VRB value, and the relative VRB value is equal to 0, the VRB value indicates that non-linear precoding is not performed. Based on this, when the VRB value is indicated by RRC signaling, MAC signaling, or DCI, it is stated that the precoding technique adopted by the network device is a linear precoding technique. For example, when the at least one parameter includes a transmission layer and the DCI indicates that the relative VRB value is equal to 0, the network device is configured to precode the signal to be transmitted of each transmission layer by using a linear precoding technique, or the network device is configured to precode the signal to be transmitted of the transmission layer corresponding to the relative VRB value by using a linear precoding technique. Other examples are not listed.
