[0022] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0023] It should be noted that in this disclosure, expressions such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplarily" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs.

Therefore, a feature defined with the terms "first," "second," and the like may explicitly or implicitly include one or more of such features.

"And / or" herein is simply a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can mean: only A, only B, and A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0026] In traditional mobile communications, the demodulation reference signal (DRS) plays a crucial role in assisting the receiver in data demodulation and channel estimation. The transmitter transmits the DRS through the antenna port, and the receiver performs data demodulation based on the received DRS.

[0027] However, in the process of transmitting the demodulation reference signal, the demodulation reference signal requires separate transmission resources for transmission, which will cause a waste of transmission resources and lead to a reduction in the spectrum efficiency of the mobile communication system.

[0028] To address the above technical issues, embodiments of the present disclosure provide a resource configuration method in which a first node indicates to a second node, via first configuration information, transmission resources for multiplexing reference signals and data channels. This allows the reference signals to be transmitted using the same transmission resources as the data channels, improving transmission resource utilization and thereby increasing spectrum efficiency.

[0029] The resource configuration method provided in the embodiment of the present disclosure can be applied to the resource configuration system as shown in FIG1 . As shown in FIG1 , the resource configuration system includes: a first node 101 and a second node 102 .

[0030] The first node 101 and the second node 102 are in communication connection.

[0031] In some embodiments, the first node 101 may be a base station or other network-side node, and the second node 102 may be a terminal. Alternatively, the first node 101 may be a terminal, and the second node 102 may be a base station or other network-side node.

[0032] As an example, FIG1 takes the first node 101 as a base station and the second node 102 as a terminal as an example.

[0033] In some embodiments, the first node 101 is configured to generate first configuration information and send the first configuration information to the second node 102, thereby indicating to the second node 102 a multiplexed transmission resource for multiplexing a reference signal and a data channel. In addition, the first node 101 may further configure a reference signal according to the first configuration information, thereby transmitting the reference signal through the multiplexed transmission resource.

[0034] The second node 102 is configured to receive the first configuration information and determine, based on the first configuration information, a multiplexing transmission resource for multiplexing a reference signal and a data channel. The second node 102 may then receive the reference signal based on the determined multiplexing transmission resource and perform channel estimation, demodulation, and other operations based on the reference signal.

[0035] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices (such as core network devices).

[0036] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is understood by those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0037] Figure 2 shows a schematic flow chart of a resource configuration method. As shown in Figure 2, the resource configuration method includes S201 and S202.

[0038] S201: A first node generates first configuration information.

[0039] The first configuration information is used to indicate the multiplexed transmission resource for multiplexing the reference signal and the data channel. In the present disclosure, the reference signal can be a demodulation reference signal (also referred to as a pilot, a demodulation reference signal pilot, etc.), or other types of reference signals, such as: Channel State Information Reference Signal (CSI RS), Sounding Reference Signal (SRS), Phase Tracking Reference Signal (PT RS), Positioning Reference Signal (PRS), etc., which is not limited in the present disclosure.

[0040] In some implementations, the first node may determine a multiplexed transmission resource for multiplexing a reference signal and a data channel, and generate first configuration information based on description information (e.g., location, identifier, etc.) of the multiplexed transmission resource. In this way, the first node may indicate the multiplexed transmission resource through the description information of the multiplexed transmission resource included in the first configuration information.

[0041] It should be noted that after generating the first configuration information, the first node can transmit a reference signal based on the multiplexed transmission resource, so that the second node can determine the reference signal transmitted by the multiplexed transmission resource based on the first configuration information and perform channel processing through the reference signal.

[0042] Taking the reference signal as a demodulation reference signal as an example, Figure 3 shows a schematic diagram of a multiplexed transmission resource for transmitting a demodulation reference signal and data. In Figure 3, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 3, the multiple transmission resources include transmission resources occupied by the data channel for transmitting data (i.e., the squares in the figure only include the word "data"), transmission resources for transmitting pilots (i.e., the squares in the figure only include pilots), and transmission resources multiplexed with pilots and data channels (i.e., the squares in the figure including data + pilots). In traditional mobile communication systems, the transmission resources occupied by the data channel for transmitting data and the transmission resources used for transmitting pilots are orthogonal (i.e., the transmission resources occupied by the data channel and the transmission resources for transmitting pilots are different, or have no intersection). In the mobile communication system of the embodiment of the present disclosure, the first node can transmit data and pilots (i.e., the squares in Figure 3 including data + pilots) through multiplexed transmission resources, thereby improving the utilization of transmission resources and improving spectrum efficiency.

[0043] S202: The first node sends first configuration information to the second node.

[0044] In some embodiments, after generating the first configuration information, the first node may send the first configuration information to the second node through a control channel; or, the first node may send the first configuration information to the second node through high-layer signaling; or, the first node may send the first configuration information to the second node through other means; this disclosure is not limited to this.

[0045] In this way, by multiplexing the same transmission resources for the reference signal and the data channel, the utilization rate of the transmission resources can be improved and the spectrum efficiency can be improved.

[0046] It should be pointed out that in the 4th Generation Mobile Communication Technology (4G) standard and the 5th Generation Mobile Communication Technology (5G) standard, the configuration of the demodulation reference signals sent by different antenna ports is consistent, for example, the number of time domain symbols is the same, the number of frequency domain subcarriers is the same, and the channel processing method corresponding to the demodulation reference signals is the same. This will result in poor flexibility in the configuration method of the demodulation reference signals and will not be able to adapt to the intelligent transmission requirements in different business scenarios in future complex networks.

[0047] To address this technical issue, the first node can flexibly configure which transmission resource the reference signal and data channel are multiplexed on, and send first configuration information to the second node to indicate the transmission resource to be multiplexed between the reference signal and the data channel. This makes the configuration of the reference signal more flexible and can adapt to diverse needs.

[0048] In some embodiments, in addition to indicating the multiplexed transmission resources for the reference signal and data channel, the first configuration information may also indicate other information. For example, information related to the multiplexed transmission resources (referred to as scenario 1) and / or information related to non-multiplexed transmission resources (referred to as scenario 2) is indicated. Scenario 1 and scenario 2 are described in detail below.

[0049] Scenario 1: The first configuration information indicates relevant information of the multiplexing transmission resource.

[0050] The relevant information of the above-mentioned multiplexed transmission resources includes but is not limited to at least one of the following: the power of the reference signal on the multiplexed transmission resources, the sequence information of the reference signal on the multiplexed transmission resources, the power of the data channel on the multiplexed transmission resources, the channel processing method corresponding to the reference signal, and the modulation information of the data channel.

[0051] The reference signal on a multiplexed transmission resource refers to a reference signal transmitted on a transmission resource that is multiplexed with a reference signal and a data channel. Accordingly, the power of the reference signal on a multiplexed transmission resource is the power of the reference signal transmitted on a transmission resource that is multiplexed with a reference signal and a data channel. It should be noted that the power in the embodiments of this disclosure includes transmit power.

[0052] The sequence information of the reference signal on the multiplexed transmission resource may include, but is not limited to, sequence length, sequence generation method, etc. Sequence generation methods may include, but are not limited to, the longest linear feedback shift register sequence (m-sequence), gold sequence, chirp sequence, Zadoff-Chu (ZC) sequence, pseudo-random sequence, nonlinearly generated sequence based on artificial intelligence, etc., and sequence that can be searched by a computer.

[0053] The data channel on the multiplexed transmission resource refers to the data channel of data transmitted on the transmission resource multiplexed with the reference signal and the data channel. Accordingly, the power of the data channel on the multiplexed transmission resource is the power of the data channel of data transmitted on the transmission resource multiplexed with the reference signal and the data channel.

[0054] The channel processing method corresponding to the reference signal refers to description information of a method for channel processing performed by the second node based on the received reference signal. In some embodiments, the method can be a linear method or a nonlinear method, such as a minimum mean square error algorithm, a least squares algorithm, a compressed sensing algorithm, a nonlinear method based on artificial intelligence, or an expectation-based statistical algorithm.

[0055] The modulation information of the data channel refers to the modulation method used when the data channel transmits data.

[0056] Scenario 2: The first configuration information indicates relevant information of non-multiplexed transmission resources.

[0057] The relevant information of the above-mentioned non-multiplexed transmission resources includes but is not limited to at least one of the following: non-multiplexed transmission resources occupied by reference signals other than multiplexed transmission resources, power of reference signals on non-multiplexed transmission resources and sequence information of reference signals on non-multiplexed transmission resources.

[0058] A reference signal on a non-multiplexed transmission resource is a reference signal transmitted via non-multiplexed transmission resources. The sequence information and power of the reference signal on the non-multiplexed transmission resource can be referenced. The sequence information and power of the reference signal on the multiplexed transmission resource are not further described in detail in the embodiments of this disclosure.

[0059] In some embodiments, the first node may transmit the reference signal using multiplexed transmission resources multiplexed with the data channel, or may transmit the reference signal independently using ordinary transmission resources. Therefore, the first configuration information may also be used to indicate non-multiplexed transmission resources used to transmit only the reference signal, i.e., transmission resources other than the multiplexed transmission resources among the transmission resources occupied by the reference signal.

[0060] The above describes the related contents of the multiplexed transmission resources and non-multiplexed transmission resources indicated by the first configuration information. Below, the multiplexed transmission resources and non-multiplexed transmission resources in the embodiment of the present disclosure will be described in detail, taking the transmission resources including time domain resources and frequency domain resources as an example.

[0061] First, the frequency domain resources of the multiplexed transmission resources and the non-multiplexed transmission resources are described in detail.

[0062] First, the location of frequency domain resources on time domain resources is described: In some embodiments, the frequency domain resources of multiplexed transmission resources include a first subcarrier, and the frequency domain resources of non-multiplexed transmission resources include a second subcarrier. The first subcarrier and the second subcarrier are located on different time domain resources; and / or the first subcarrier and the second subcarrier are located on the same time domain resource.

[0063] In some embodiments, the time domain resources may include orthogonal frequency division multiplexing (OFDM) symbols (also referred to as time domain symbols). Therefore, the first subcarrier and the second subcarrier may be on the same OFDM symbol; or, the first subcarrier and the second subcarrier may be on different OFDM symbols. It is understandable that the first subcarrier and the second subcarrier on the same OFDM symbol may be referred to as the first subcarrier and the second subcarrier on the same time region; the first subcarrier and the second subcarrier on different OFDM symbols may be referred to as the first subcarrier and the second subcarrier on different time regions.

[0064] It should be noted that since the number of first subcarriers and second subcarriers can be multiple, some of the multiple first subcarriers can be in the same time domain resources as some of the second subcarriers, and another part of the first subcarriers can be in different time domain resources as another part of the second subcarriers.

[0065] Taking the reference signal as a demodulation reference signal as an example, Figure 4 shows a schematic diagram of a first subcarrier and a second subcarrier in different time domain resources. In Figure 4, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 4, multiple transmission resources include transmission resources occupied by data channels for transmitting data (that is, the squares in the figure only include the word "data"), transmission resources for transmitting pilots (that is, the squares in the figure only include pilots), and transmission resources multiplexed with pilots and data channels (that is, the squares in the figure include data + pilots). Since the horizontal axis represents the time domain and the vertical axis represents the frequency domain, the transmission resources are represented as subcarriers on the vertical axis and the transmission resources are represented as time domain resources on the horizontal axis. The first subcarrier of the multiplexed transmission resource and the second subcarrier of the non-multiplexed transmission resource are both in different time regions (that is, the horizontal axes of the first subcarrier and the second subcarrier are different).

[0066] Taking the reference signal as a demodulation reference signal as an example, Figure 5 shows a schematic diagram of a first subcarrier and a second subcarrier in the same time domain resource. In Figure 5, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 5, multiple transmission resources include transmission resources occupied by data channels for transmitting data (that is, the squares in the figure only include the word "data"), transmission resources for transmitting pilots (that is, the squares in the figure only include pilots), and transmission resources multiplexed with pilots and data channels (that is, the squares in the figure include data + pilots). Since the horizontal axis represents the time domain and the vertical axis represents the frequency domain, the transmission resources are represented as subcarriers on the vertical axis and the transmission resources are represented as time domain resources on the horizontal axis. The first subcarrier of the multiplexed transmission resource and the second subcarrier of the non-multiplexed transmission resource are in the same time region (that is, the horizontal axis of the first subcarrier and the second subcarrier are the same).

[0067] Secondly, the number of frequency domain resources is described: In the embodiment of the present disclosure, the relationship between the number of frequency domain resources of the multiplexed transmission resources and the number of frequency domain resources of the non-multiplexed transmission resources includes but is not limited to any one of the following cases 1 to 4, which are described in detail below:

[0068] Case 1: the number of first subcarriers in any first time domain symbol is less than or equal to the number of second subcarriers in any second time domain symbol.

[0069] The first time domain symbol is a time domain symbol occupied by multiplexed transmission resources, and / or a time domain symbol jointly occupied by multiplexed transmission resources and non-multiplexed transmission resources; the second time domain symbol is a time domain symbol occupied by non-multiplexed transmission resources, and / or a time domain symbol jointly occupied by multiplexed transmission resources and non-multiplexed transmission resources.

[0070] Taking the reference signal as a demodulation reference signal as an example, Figure 7 shows a schematic diagram in which the number of first subcarriers in any first time domain symbol is less than or equal to the number of second subcarriers in any second time domain symbol. In Figure 7, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 7, multiple transmission resources include transmission resources occupied by data channels for transmitting data (i.e., squares that only include the word "data" in the figure), transmission resources for transmitting pilots (i.e., squares that only include pilots in the figure), and transmission resources multiplexed with pilots and data channels (i.e., squares that include data + pilots in the figure). Since the horizontal axis represents the time domain, a vertical column can be used to represent a time domain symbol. As shown in Figure 7, the number of first subcarriers in the first time domain symbol of the multiplexed transmission resource is 1 or 2. The number of second subcarriers in the second time domain symbol of the non-multiplexed transmission resource is 2. Therefore, the number of first subcarriers in any first time domain symbol is less than or equal to the number of second subcarriers in any second time domain symbol.

[0071] Case 2: the number of first subcarriers in any first time domain symbol is less than or equal to the number of second subcarriers in any second time domain symbol.

[0072] Taking the reference signal as a demodulation reference signal as an example, Figure 8 shows a schematic diagram in which the number of first subcarriers in any first time domain symbol is greater than the number of second subcarriers in any second time domain symbol. In Figure 8, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 8, multiple transmission resources include transmission resources occupied by data channels for transmitting data (i.e., squares that only include data in the figure), transmission resources for transmitting pilots (i.e., squares that only include pilots in the figure), and transmission resources multiplexed with pilots and data channels (i.e., squares that include data + pilots in the figure). Since the horizontal axis represents the time domain, a vertical column can be used to represent a time domain symbol. As shown in Figure 8, the number of first subcarriers in the first time domain symbol of the multiplexed transmission resource is 3, and the number of second subcarriers in the second time domain symbol of the non-multiplexed transmission resource is 2. Therefore, the number of first subcarriers in any first time domain symbol is greater than the number of second subcarriers in any second time domain symbol.

[0073] Case 3: The number of first subcarriers in the multiplexed transmission resources is greater than the number of second subcarriers in the non-multiplexed transmission resources.

[0074] Case 4: the number of first subcarriers in the multiplexed transmission resources is less than or equal to the number of second subcarriers in the non-multiplexed transmission resources.

[0075] It should be pointed out that for cases three and four, the number of first subcarriers in the multiplexed transmission resources is the number of all first subcarriers occupied in all multiplexed transmission resources, and the number of second subcarriers in the non-multiplexed transmission resources is the number of all second subcarriers occupied in all non-multiplexed transmission resources.

[0076] Second, a detailed description is given of the time domain resources of the multiplexed transmission resources and the non-multiplexed transmission resources.

[0077] In some embodiments, the time domain resources of the multiplexed transmission resources include a first time domain symbol; the time domain resources of the non-multiplexed transmission resources include a second time domain symbol; and the first time domain symbol is located after the second time domain symbol.

[0078] It can be understood that the first time domain symbol of the multiplexed transmission resource is located after the second time domain symbol of the non-multiplexed transmission resource, which can also be understood as: the first node first sends a reference signal to the second node on the non-multiplexed transmission resource, and then sends a reference signal to the second node on the multiplexed transmission resource. Because the reference signal on the multiplexed transmission resource will be affected by the data to be transmitted by the data channel on the multiplexed transmission resource, and the reference signal on the non-multiplexed transmission resource will not be affected by the data. Therefore, the first node first sends a reference signal to the second node on the non-multiplexed transmission resource, which allows the second node to determine the channel information based on the unaffected reference signal on the non-multiplexed transmission resource, thereby making the determined channel information more accurate. After this, the first node sends a reference signal to the second node on the multiplexed transmission resource, and the second node jointly determines the channel information based on the reference signals on the non-multiplexed transmission resource and the multiplexed transmission resource, saving transmission resources for transmitting the reference signal without affecting the accuracy of the channel information.

[0079] Taking the reference signal as a demodulation reference signal as an example, Figure 6 shows a schematic diagram in which a first time domain symbol is located after a second time domain symbol. In Figure 6, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 6, multiple transmission resources include transmission resources occupied by data channels for transmitting data (i.e., squares that only include the word "data" in the figure), transmission resources for transmitting pilots (i.e., squares that only include pilots in the figure), and transmission resources multiplexed with pilots and data channels (i.e., squares that include data + pilots in the figure). Since the horizontal axis represents the time domain, a vertical column can be used to represent a time domain symbol. As shown in Figure 6, the time domain can represent time, and the multiplexed transmission resource is located after the non-multiplexed transmission resource on the horizontal axis (i.e., in time), that is, the first time domain symbol of the multiplexed transmission resource is located after the second time domain symbol of the non-multiplexed transmission resource.

[0080] It should be noted that the first time domain symbol may also be located before the second time domain symbol, or the first time domain symbol and the second time domain symbol may also be the same time domain symbol.

[0081] Third, with respect to the modulation information of the data channel, the number of bits corresponding to the modulation symbols of the multiplexed transmission resources and other transmission resources is described in detail.

[0082] In some embodiments, the modulation information of the data channel includes at least two modulation modes, and the at least two modulation modes include a modulation mode of the data channel on the multiplexed transmission resources and a modulation mode of the data channel on other transmission resources; the other transmission resources are transmission resources occupied by the data channel other than the multiplexed transmission resources; the number of bits corresponding to each modulation symbol of the data channel on the multiplexed transmission resources is less than or equal to the number of bits corresponding to each modulation symbol of the data channel on other transmission resources.

[0083] In some embodiments, the multiplexed transmission resources are transmission resources multiplexed by data channels and reference signals, and other transmission resources are transmission resources occupied by data channels other than the multiplexed transmission resources, that is, transmission resources used only for transmitting data. When the first node transmits data through the transmission resources, it can modulate the data through a modulation method to obtain a modulation symbol corresponding to each data. During the modulation process, the first node can modulate the data to be transmitted by the multiplexed transmission resources and the data to be transmitted by other transmission resources through different modulation methods. Moreover, the number of bits corresponding to each modulation symbol on the multiplexed transmission resources can be less than or equal to the number of bits corresponding to each modulation symbol on other transmission resources. In addition, since the data on the multiplexed transmission resources and the data on other transmission resources use different modulation methods, the interference between the reference signal and the data to be transmitted by the data channel can be reduced, thereby improving the accuracy of channel estimation.

[0084] It should be noted that the modulation mode of the data channel on other transmission resources may be one or more. Therefore, the modulation information of the data channel includes at least two modulation modes.

[0085] Taking the reference signal as a demodulation reference signal as an example, Figure 9 shows a schematic diagram in which the number of bits corresponding to each modulation symbol of a data channel on a multiplexed transmission resource is less than or equal to the number of bits corresponding to each modulation symbol of the data channel on other transmission resources. In Figure 9, the horizontal axis is the time domain, the vertical axis is the frequency domain, and each square is a transmission resource in the time domain and the frequency domain. As shown in Figure 9, the multiple transmission resources include transmission resources occupied by the data channel for transmitting data (i.e., the squares in the figure only include data), transmission resources for transmitting pilots (i.e., the squares in the figure only include pilots), and transmission resources multiplexed with pilots and data channels (i.e., the squares in the figure include data + pilots).

[0086] The modulation scheme for data on the multiplexed transmission resource is Quadrature Phase Shift Keying (QPSK), while the modulation scheme for data on other transmission resources is 256-ary Quadrature Amplitude Modulation (256QAM). Due to the different modulation schemes, the number of bits corresponding to each modulation symbol on the multiplexed transmission resource is different from the number of bits corresponding to each modulation symbol on the other transmission resources. In addition, the number of bits corresponding to each modulation symbol on the multiplexed transmission resource is less than or equal to the number of bits corresponding to each modulation symbol on the other transmission resources.

[0087] Fourth, a detailed description is given of the power of the reference signal on the multiplexed transmission resource and the power of the data channel on the multiplexed transmission resource.

[0088] In some embodiments, the sum of the power of the reference signal on the multiplexed transmission resource and the power of the data channel on the multiplexed transmission resource is greater than or equal to the power of the data channel on other transmission resources; other transmission resources are transmission resources occupied by the data channel other than the multiplexed transmission resources.

[0089] In some implementations, when configuring transmission resources, the first node may make the sum of the power of the reference signal on the multiplexed transmission resource and the power of the data channel on the multiplexed transmission resource greater than or equal to the power of the data channel on other transmission resources.

[0090] In the above, the multiplexed transmission resources and non-multiplexed transmission resources in the embodiment of the present disclosure are described in detail, taking the transmission resources including time domain resources and frequency domain resources as an example. The following describes in detail the manner in which multiple parameters in the first configuration information are indicated by fields.

[0091] In some embodiments, the first configuration information includes any one of the following: a first field, a second field, a third field, a fourth field, or a fifth field. These different fields are used to indicate different contents in the first configuration information. The first field, the second field, the third field, the fourth field, and the fifth field are described in detail below.

[0092] Regarding the first field: the first field is used to indicate the multiplexed transmission resource, the power of the reference signal on the multiplexed transmission resource, and the power of the data channel on the multiplexed transmission resource.

[0093] Regarding the second field: the second field is used to indicate the power of the reference signal on the multiplexed transmission resource, the power of the data channel on the multiplexed transmission resource, and the modulation method of the data channel on the multiplexed transmission resource.

[0094] Regarding the third field: the third field is used to indicate the multiplexed transmission resources, the power of the reference signal on the multiplexed transmission resources, the power of the data channel on the multiplexed transmission resources, and the modulation method of the data channel on the multiplexed transmission resources.

[0095] Regarding the fourth field: the fourth field is used to indicate the power of the reference signal on the multiplexed transmission resource, the power of the data channel on the multiplexed transmission resource, and the modulation information of the data channel.

[0096] Regarding the fifth field: the fifth field is used to indicate the multiplexed transmission resources, the power of the reference signal on the multiplexed transmission resources, the power of the data channel on the multiplexed transmission resources, and the modulation information of the data channel.

[0097] It should be noted that the modulation information of the data channel includes the modulation mode of the data channel on the multiplexed transmission resource.

[0098] In some embodiments, the first configuration information may be transmitted via downlink control information (DCI), and accordingly, the downlink control information includes any one of the first field, second field, third field, fourth field, or fifth field in the first configuration information.

[0099] In some implementations, the first node may indicate a parameter combination through a field (e.g., a first field, a second field, a third field, a fourth field, and a fifth field) in downlink control information (or through higher layer signaling, media access control signaling, or physical layer signaling, etc.). The parameter combination may include at least one of the following: multiplexed transmission resources, power of a reference signal on the multiplexed transmission resources, power of a data channel on the multiplexed transmission resources, modulation mode of the data channel on the multiplexed transmission resources, and modulation information of the data channel.

[0100] The first configuration information can indicate a parameter combination and the value of each parameter in the parameter combination through a single field. In this way, the second node can determine the parameter combination to be transmitted and the value of each parameter in the parameter combination through a single field, thereby saving fields and transmission resources.

[0101] Taking the first configuration information including the first field as an example, as shown in Table 1, the values ​​of the first field include 1 and 2. When the value of the first field is 1, the first field is used to indicate the first set of configuration information, which is a set of parameter values ​​for multiplexing transmission resources, the power of reference signals on multiplexing transmission resources, and the power of data channels on multiplexing transmission resources. When the value of the first field is 2, the first field indicates the second set of configuration information, which is another set of parameter values ​​for multiplexing transmission resources, the power of reference signals on multiplexing transmission resources, and the power of data channels on multiplexing transmission resources.

[0102] Table 1

[0103] The above describes in detail the manner in which fields indicate multiple parameters in the first configuration information. The following describes in detail the parameters indicated by the first configuration information through modulation information of the data channel.

[0104] In some embodiments, the modulation information of the data channel determines the value of the number of multiplexed transmission resources.

[0105] Alternatively, the modulation information of the data channel determines the value of the power of the reference signal on the multiplexed transmission resource and / or the value of the power of the data channel on the multiplexed transmission resource.

[0106] Alternatively, the modulation information of the data channel determines the value of the number of non-multiplexed transmission resources, where the non-multiplexed transmission resources are transmission resources occupied by reference signals other than the multiplexed transmission resources.

[0107] Alternatively, the modulation information of the data channel determines the value of the sequence generation mode of the reference signal on the multiplexed transmission resource and / or the value of the sequence generation mode of the reference signal on the non-multiplexed transmission resource.

[0108] In some implementations, the first node can determine the values ​​of certain parameters based on the modulation information of the data channel, such as the number of multiplexed transmission resources, the power of reference signals on multiplexed transmission resources, the number of non-multiplexed transmission resources, the sequence generation method for reference signals on multiplexed transmission resources, and the sequence generation method for reference signals on non-multiplexed transmission resources. In this way, after receiving the first configuration information, the second node can determine the values ​​of the aforementioned parameters based on the modulation information of the data channel indicated by the first configuration information, thereby saving fields and transmission resources.

[0109] Regarding the value of the number of multiplexed transmission resources, the first node can determine the value of the number of multiplexed transmission resources based on the modulation mode in the modulation information of the data channel. For example, the first node can determine that the modulation mode of the data channel in the modulation information of the data channel is 256QAM, then the first node can determine that the ratio of the number of multiplexed transmission resources to the number of all transmission resources occupied by the data channel does not exceed 10%. When the first node determines that the modulation mode of the data channel in the modulation information of the data channel is 64QAM, then the first node can determine that the ratio of the number of multiplexed transmission resources to the number of all transmission resources occupied by the data channel does not exceed 30%.

[0110] It should be noted that the first node can use two fields to respectively indicate the modulation mode of the data channel and the number of multiplexed transmission resources (or the power of the reference signal on the multiplexed transmission resources, the number of non-multiplexed transmission resources, the sequence generation method of the reference signal on the multiplexed transmission resources, and the sequence generation method of the reference signal on the non-multiplexed transmission resources). For example: the first node can use fields to indicate the modulation information of the data channel and the number of multiplexed transmission resources. When the first "1" in the field "11" indicates that the modulation mode of the data channel in the modulation information of the data channel is 256QAM, the second "1" in "11" can indicate that the number of multiplexed transmission resources is 5. When the "0" in the field "01" indicates that the modulation mode of the data channel in the modulation information of the data channel is 64QAM, the "1" in "01" can indicate that the number of multiplexed transmission resources is 10.

[0111] With respect to the value of the power of the reference signal on the multiplexed transmission resource, and / or the value of the power of the data channel on the multiplexed transmission resource, the first node can determine the value of the power of the reference signal on the multiplexed transmission resource, and / or the value of the power of the data channel on the multiplexed transmission resource through the modulation mode in the modulation information of the data channel. For example, the first node can determine that the modulation mode of the data channel in the modulation information of the data channel is 256QAM, then the first node can determine that the difference between the power of the reference signal on the multiplexed transmission resource and the power of the reference signal on the non-multiplexed transmission resource is not less than 50%. When the modulation mode of the data channel is 64QAM, the first node can determine that the difference between the power of the reference signal on the multiplexed transmission resource and the power of the reference signal on the non-multiplexed transmission resource is not less than 30%.

[0112] Regarding the value of the number of non-multiplexed transmission resources, the first node can determine the value of the number of non-multiplexed transmission resources according to the modulation mode in the modulation information of the data channel. For example: the first node can determine that the modulation mode of the data channel in the modulation information of the data channel is 256QAM, then the ratio of the number of non-multiplexed transmission resources to the number of all transmission resources occupied by the data channel does not exceed 5%, for example, the number of non-multiplexed transmission resources does not exceed 5% of the number of all transmission resources occupied by the data channel. When the modulation mode of the data channel is 64QAM, the ratio of the number of non-multiplexed transmission resources to the number of all transmission resources occupied by the data channel does not exceed 15%, for example, the number of non-multiplexed transmission resources does not exceed 15% of the number of all transmission resources occupied by the data channel.

[0113] Regarding the value of the sequence generation mode of the reference signal on the multiplexed transmission resource, and / or the value of the sequence generation mode of the reference signal on the non-multiplexed transmission resource, the first node can determine that the data channel modulation mode in the modulation information of the data channel is 256QAM, then the first node can select the sequence generation mode corresponding to 256QAM from multiple sequence generation modes (assuming eight modes) (for example, the first four modes of the eight modes); when the modulation mode of the data channel is 64QAM, the sequence generation mode corresponding to 64QAM from multiple sequence generation modes can be selected (for example, the last four modes of the eight modes).

[0114] It should be noted that all transmission resources occupied by the data channel include other transmission resources and multiplexed transmission resources occupied by the data channel.

[0115] Regarding the second node receiving the first configuration information sent by the first node, the relevant description of the first configuration information can refer to the specific description of the first configuration information sent by the first node mentioned above, and the embodiment of the present disclosure will not be repeated here.
