Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method for signal transmission and related equipment. Background Technology

[0002] In Long Term Evolution (LTE) systems, in order to improve the efficiency of transmitting or receiving data signals, data signals can be transmitted through multiple resources (such as multiple resource blocks, multiple resource block groups, etc.). For example, data signals can be transmitted to the receiving end on multiple resource blocks.

[0003] However, different resource blocks correspond to different channels, and the channel quality varies. When data signals are transmitted on different resource blocks, the data signals are usually transmitted based on the same modulation and coding scheme (MCS) and the same transmission power. Resource blocks with weaker channel quality may not be able to successfully complete the transmission of data signals, resulting in the receiver not being able to accurately receive the data signals. Summary of the Invention

[0004] This application provides a signal transmission method and related equipment, which can improve the transmission quality of data signals and ensure that the receiving end can accurately receive data signals.

[0005] A first aspect of this application provides a signal transmission method, comprising: in uplink scheduling, a terminal device first receives indication information from a network device, the indication information indicating: multiple resources for transmitting uplink data signals, at least one MCS (Multi-Segment Control), and at least one power parameter. Then, the terminal device determines the MCS corresponding to each resource and the power parameter corresponding to each resource based on the indication information, determines the uplink data signal corresponding to each resource based on the MCS corresponding to each resource, and determines the transmission power of the uplink data signal corresponding to each resource based on the power parameter corresponding to each resource. Finally, the terminal device transmits uplink data signals to the network device on the corresponding resources based on the transmission power and the uplink data signal corresponding to each resource, thereby completing the uplink scheduling.

[0006] As can be seen from the above method, network devices can indicate multiple resources, at least one MCS, and at least one power parameter to terminal devices through indication information. This allows terminal devices to send data signals to network devices using different MCS and / or different transmission powers on different resources based on the indication information, thereby improving the transmission quality of data signals and ensuring that network devices can accurately receive data signals.

[0007] In one possible implementation, the indication information is used to indicate multiple power parameters, where each resource corresponds to one power parameter, and at least two power parameters are different. Specifically, the indication information indicates multiple power parameters, and each resource corresponds to one power parameter, so the power parameter corresponding to each resource can be determined based on the indication information. Among these power parameters, at least two resources have different power parameters. It can be understood that if two resources have the same power parameter, then the transmission power of the uplink data signal corresponding to these two resources is the same; if two resources have different power parameters, then the transmission power of the uplink data signal corresponding to these two resources is different.

[0008] In one possible implementation, the transmission power of the demodulation reference signal corresponding to each resource is the same, and the transmission power of the uplink data signal corresponding to at least two resources is different. Specifically, by setting the transmission power of the demodulation reference signal corresponding to all resources to the same preset value, the transmission power of the uplink data signal corresponding to each resource can be determined based on this same preset value and the power parameter corresponding to each resource.

[0009] In one possible implementation, the indication information is used to indicate multiple MCSs, where each resource corresponds to one MCS, and at least two MCSs are different. Specifically, the indication information is used to indicate multiple MCSs, and each resource corresponds to one MCS, so the MCS corresponding to each resource can be determined based on the indication information. In this subset of MCSs, at least two resources have different corresponding MCSs.

[0010] In one possible implementation, different resources correspond to different frequency domain resource locations. Specifically, MCS and power parameters are assigned to multiple resources with different frequency domain resource locations to achieve data signal transmission using different MCS and / or transmit power on the multiple resources with different frequency domain resource locations.

[0011] In one possible implementation, the larger the MCS (Multi-Segment Control) of a resource, the greater the transmission power of the uplink data signal corresponding to that resource. Specifically, the larger the MCS of a resource, the greater the transmission power of the uplink data signal corresponding to that resource; conversely, the smaller the MCS of a resource, the smaller the transmission power of the uplink data signal corresponding to that resource.

[0012] In one possible implementation, the power parameter can be: the ratio between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal; or, the difference between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal. Specifically, since the power parameter is used to indicate the correspondence between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal, the transmission power corresponding to each resource can be determined based on the power parameter corresponding to each resource. The transmission power corresponding to each resource includes the transmission power of the uplink data signal corresponding to that resource and the transmission power of the demodulation reference signal corresponding to that resource.

Those skilled in the art will understand that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in this application embodiment are also applicable to similar technical problems.

[0118] To facilitate understanding, the following will combine... Figure 1 The application scenarios of the embodiments of this application will be briefly introduced. Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application, such as... Figure 1 As shown, this application scenario includes a terminal device 101 and a network device 102. The terminal device 101 is wirelessly connected to the network device 102, and the network device 102 is used to connect the terminal device 101 to the wireless network.

[0119] Among them, terminal equipment 101, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users, or a chip set in the device, such as a handheld device or in-vehicle device with wireless connectivity. Examples of terminal devices currently include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes.

[0120] Network device 102 can be any device with wireless transceiver capabilities, or a chip embedded within a device with specific wireless transceiver capabilities. Network device 102 includes, but is not limited to: base stations (e.g., base station BS, base station NodeB, evolved NodeB or eNB, gNodeB or gNB in ​​a 5G communication system, base stations in future communication systems, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes, etc.). Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using one or more of the technologies mentioned above, or future evolved networks. A base station can contain one or more co-located or non-co-located transmission reception points (TRPs). Network device 102 can also be a wireless controller, central unit (CU), or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The following explanation uses network device 102 as an example of a base station. The multiple network devices 102 can be base stations of the same type or different types. The base station can communicate with the terminal device 101, or it can communicate with the terminal device 101 through a relay station. The terminal device 101 can support communication with multiple base stations using different technologies. For example, the terminal device 101 can support communication with base stations supporting LTE networks, base stations supporting 5G networks, and dual connectivity with both LTE and 5G network base stations. For example, the terminal device 101 can be connected to a RAN node in a wireless network. Examples of RAN nodes include: gNB, TRP, evolved Node B (eNB), next-generation evolved Node B (LTE ng-eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or Wi-Fi access point (AP), etc.

[0121] Figure 2 A schematic flowchart of a signal transmission method provided in an embodiment of this application is shown below. Figure 2 As shown, the method includes:

[0122] 201. The terminal device receives instruction information from the network device.

[0123] In uplink scheduling, network devices may first send indication information to terminal devices, which indicates: multiple resources for transmitting uplink data signals, at least one MCS, and at least one power parameter.

[0124] In this embodiment, the indication information can be presented in multiple ways:

[0125] In one possible implementation, the indication information may simultaneously indicate multiple resources used for transmitting uplink data signals, at least one modulation and coding scheme (MCS), and at least one power parameter.

[0126] In another possible implementation, the indication information may include a first sub-indication information and a second sub-indication information, wherein the first sub-indication information is used to indicate multiple resources for transmitting uplink data signals, and the second sub-indication information is used for at least one modulation and coding scheme (MCS) and at least one power parameter.

[0127] Furthermore, in the two aforementioned implementation methods, the indication information, the first sub-indication information, and the second sub-indication information can be any of the following: downlink control information (DCI), radio resource control (RRC) signaling, and media access layer control element (MAC CE).

[0128] After receiving the indication information, the terminal device can determine multiple resources used for transmitting uplink data signals. It should be noted that these multiple resources are those occupied by the Physical Uplink Shared Channel (PUSCH). In this embodiment, a resource is a concept with multi-dimensional information (frequency domain information, time domain information, spatial domain information, etc.). Specifically, among the multiple resources, different resources correspond to different resource locations, which include at least one of the following: frequency domain resource location, time domain resource location, and spatial domain resource location. Different frequency domain resource locations can refer to different frequency bands; different time domain resource locations can refer to different numbers of orthogonal frequency division multiplexing (OFDM) symbols or different numbers of time slots, etc.; different spatial domain resource locations can refer to different antenna ports, different transmission layers, or different data streams, etc.

[0129] In this embodiment, resources can be specifically described by resource elements (REs), resource blocks (RBs), or resource block groups (RBGs). For example, a resource block allocated to the first frequency band and a resource block allocated to the second frequency band can be regarded as two resources with different frequency resource locations. Similarly, a resource block allocated to two antenna ports can be regarded as two resources with different spatial resource locations. Furthermore, a resource block allocated to the first frequency band and the first antenna port, and a resource block allocated to the second frequency band and the second antenna port can be regarded as two resources with different frequency resource locations and spatial resource locations, and so on.

[0130] Furthermore, based on the indication information, the terminal device can also determine at least one MCS and at least one power parameter, wherein there is a correspondence between MCSs and resources, and also a correspondence between power parameters and resources. This correspondence can be presented in various ways based on the number of MCSs and the number of power parameters:

[0131] In one possible implementation, when the indication information indicates multiple MCSs and a power parameter, each resource corresponds to one MCS, and at least two MCSs are different. Furthermore, the power parameter corresponds to all resources. For example, when the indication information indicates MCS1, MCS2, MCS3, and power parameter 1, and resources 1, 2, and 3 exist, then resource 1 corresponds to MCS1 (i.e., resource 1 uses MCS1), resource 2 corresponds to MCS2, resource 3 corresponds to MCS3, and power parameter 1 corresponds to resources 1, 2, and 3 (i.e., resources 1, 2, and 3 all use power parameter 1). Among MCS1, MCS2, and MCS3, at least two MCSs are different. For example, MCS1 and MCS2 may be the same, while MCS3 may be different from MCS1; or all three MCSs may be different, and so on.

[0132] In another possible implementation, when the indication information indicates multiple power parameters and one MCS, each resource corresponds to one power parameter among the multiple power parameters, and at least two power parameters are different. Furthermore, the MCS corresponds to all resources. For example, when the indication information indicates power parameter 1, power parameter 2, power parameter 3, and MCS1, and resources 1, 2, and 3 exist, then resource 1 corresponds to power parameter 1, resource 2 corresponds to power parameter 2, resource 3 corresponds to power parameter 3, and MCS1 corresponds to resources 1, 2, and 3 (i.e., resources 1, 2, and 3 all use MCS1). Among power parameters 1, 2, and 3, at least two power parameters are different. For example, power parameters 1 and 3 may be the same, power parameters 2 and 1 may be different, or all three (power parameters 1, 2, and 3) may be different, and so on.

[0133] In another possible implementation, when the indication information indicates multiple MCSs and multiple power parameters, then among the multiple power parameters, each resource corresponds to one power parameter, and at least two power parameters are different. Similarly, among the multiple MCSs, each resource corresponds to one MCS, and at least two MCSs are different. For example, when the indication information indicates power parameter 1, power parameter 2, power parameter 3, MCS1, MCS2, and MCS3, and resources 1, 2, and 3 exist, then resource 1 corresponds to power parameter 1, resource 2 corresponds to power parameter 2, and resource 3 corresponds to power parameter 3. Furthermore, resource 1 corresponds to MCS1, resource 2 corresponds to MCS2, and resource 3 corresponds to MCS3. Among power parameters 1, 2, and 3, at least two power parameters are different, and among MCS1, 2, and 3, at least two MCSs are different. For example, power parameters 1, 2, and 3 are all different, and MCS1 and MCS2 are the same, while MCS3 and MCS1 are different, and so on.

[0134] For ease of explanation, the following text will use the third implementation method mentioned above.

[0135] Based on the above correspondence between MCS and resources, the terminal device can determine the MCS allocated to each resource. The MCS allocated to each resource can be used to generate the uplink data signal required for transmission by that resource. Similarly, based on the above correspondence between power parameters and resources, the terminal device can determine the power parameters allocated to each resource. The power parameters allocated to each resource can be used to determine the transmission power corresponding to that resource. The transmission power corresponding to each resource includes the transmission power of the uplink data signal corresponding to that resource, and the transmission power of the demodulation reference signal corresponding to that resource. Therefore, the power parameters can be one of the following:

[0136] The ratio between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal;

[0137] The difference between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal.

[0138] It is worth noting that when allocating MCS and transmit power to each resource, network devices can establish a certain correspondence between MCS and transmit power. In one possible implementation, the larger the MCS of a resource, the greater the transmit power of the uplink data signal corresponding to that resource. Conversely, the smaller the MCS of a resource, the smaller the transmit power of the uplink data signal. For example, the network device can first set the transmit power of the demodulation reference signals corresponding to resource 1 and resource 2 to the same value, and after setting the MCS1 of resource 1 to be greater than the MCS2 of resource 2, it can then set the transmit power of the uplink data signal corresponding to resource 1 to be greater than the transmit power of the uplink data signal corresponding to resource 2, and so on.

[0139] In this embodiment, the transmission power of the demodulation reference signal can be determined by the energy per resource element (EPRE) of the demodulation reference signal, and the transmission power of the uplink data signal can be determined by the EPRE of the uplink data signal. Therefore, the power parameter corresponding to a certain resource can also be expressed as one or more of the following:

[0140] (1) The EPRE of the demodulation reference signal corresponding to this resource;

[0141] (2) The EPRE of the uplink data signal corresponding to this resource;

[0142] (3) The ratio or difference between the EPRE of the demodulated reference signal corresponding to the resource and the average EPRE of the demodulated reference signal;

[0143] (4) The ratio or difference between the EPRE of the uplink data signal corresponding to this resource and the average EPRE of the uplink data signals corresponding to the other resources;

[0144] (5) The ratio or difference between the EPRE of the demodulation reference signal corresponding to the resource and the EPRE of the uplink data signal corresponding to the resource;

[0145] (6) The ratio or difference between the EPRE of the demodulation reference signal corresponding to this resource and the demodulation reference signal corresponding to the other resources;

[0146] (7) The ratio or difference between the EPRE of the uplink data signal corresponding to this resource and the EPRE of the uplink data signal corresponding to other resources;

[0147] (8) The ratio or difference between the EPRE of the demodulation reference signal corresponding to the resource and the reference EPRE of the demodulation data signal (for example, the EPRE of the demodulation reference signal corresponding to a certain resource can be used as the reference EPRE among multiple resources);

[0148] (9) The ratio or difference between the EPRE of the demodulation reference signal corresponding to the resource and the reference EPRE of the uplink data signal;

[0149] (10) The ratio or difference between the EPRE of the uplink data signal corresponding to the resource and the reference EPRE of the uplink data signal;

[0150] (11) The ratio or difference between the EPRE of the uplink data signal corresponding to the resource and the reference EPRE of the demodulation reference signal.

[0151] For ease of explanation, the following text will use EPRE to represent the transmission power of the signal, and the ratio or difference between the EPRE of the demodulation reference signal and the EPRE of the uplink data signal will be used as the power parameter, i.e., the aforementioned case (5).

[0152] To further understand, the following text will combine... Figure 3 and Figure 4 The correspondence between the aforementioned MCS and resources, and the correspondence between power parameters and resources, will be further explained. Figure 3 This is a schematic diagram illustrating the correspondence provided in the embodiments of this application. Figure 4 Another schematic diagram illustrating the correspondence provided in the embodiments of this application. Figure 3 and Figure 4 For ease of explanation and diagramming, two different resources are provided. These two resources have different frequency domain resource locations, but the same time domain resource location and spatial domain resource location. For example, resource block 1 is assigned to frequency band 1 and resource block 2 is assigned to frequency band 2. Resource block 1 and resource block 2 have the same number of OFDM symbols and are assigned to the same antenna port.

[0153] exist Figure 3 and Figure 4The indication information specifies resource block 1, resource block 2, power parameter 1, power parameter 2, MCS1, and MCS2. Resource block 1 corresponds to power parameter 1 and MCS1, and resource block 2 corresponds to power parameter 2 and MCS2. Power parameter 1 is the ratio between the demodulation reference signal EPRE1 and the uplink data signal EPRE2, and power parameter 2 is the ratio between the demodulation reference signal EPRE3 and the uplink data signal EPRE4.

[0154] Since the power parameter is only a ratio, it cannot fully reflect the magnitude of the EPRE of the demodulated reference signal and the EPRE of the uplink data signal. Therefore, several situations may exist:

[0155] exist Figure 3 In the case shown, power parameter 1 is different from power parameter 2, and the demodulation reference signal EPRE1 is the same as the demodulation reference signal EPRE3, while the uplink data signal EPRE2 is different from the uplink data signal EPRE4. Based on Figure 3 As shown, the EPRE of the demodulation reference signal is the same for all resources with different frequency resource locations. Therefore, if the EPRE of the same demodulation reference signal is known (which can be achieved by presetting, by indication information, or by a preset method and indication information), the EPRE of the demodulation reference signal and the EPRE of the uplink data signal for each resource can be determined based on the EPRE of the same demodulation reference signal and the power parameters corresponding to each resource.

[0156] exist Figure 4 In the case shown, power parameter 1 is different from power parameter 2, and the demodulation reference signal EPRE1 is different from the demodulation reference signal EPRE3, while the uplink data signal EPRE2 is different from the uplink data signal EPRE4. Based on Figure 4 As shown, in different resources, the power parameters of all resources are different, some resources have different power parameters, or all resources have the same power parameters. Furthermore, the EPRE of the demodulation reference signal is different for all or some resources. Therefore, it is necessary to indicate the EPRE of the demodulation reference signal or the EPRE of the uplink data signal for each resource, and then, in conjunction with the power parameters for each resource, determine the EPRE of the demodulation reference signal and the EPRE of the uplink data signal for each resource. Additionally, in... Figure 3 and Figure 4 In the two cases shown, MCS1 and MCS2 are also different.

[0157] Therefore, based on Figure 3 and Figure 4As shown in the two cases, after obtaining the power parameters, additional information is needed to determine the EPRE of the demodulated reference signal and the EPRE of the uplink data signal. For example, in Figure 3 In the scenario shown, the EPRE of all demodulation reference signals is the same. Therefore, the EPRE of this identical demodulation reference signal can be obtained first, and then the EPRE of each uplink data signal can be determined based on the EPRE of this identical demodulation reference signal and each power parameter. For example, in... Figure 4 In the scenario shown, the EPRE of each demodulated reference signal can be obtained first. Based on the EPRE of each demodulated reference signal and the corresponding power parameters, the EPRE of each uplink data signal can be determined, and so on. This will not be elaborated upon here but will be discussed in more detail later.

[0158] The following section will explain how the indication information indicates power parameters and MCS, specifically divided into individual indication and combined indication.

[0159] (a) The method of separate indication is: the indication information is indicated through different fields, respectively indicating power parameters and MCS information.

[0160] In one possible implementation, the indication information includes a first field and a second field. The first field indicates multiple power parameters, and the second field indicates multiple MCSs. The size of the first field (i.e., the number of bits contained in the first field) is determined based on the number of resources and the number of power parameter values, and the size of the second field is determined based on the number of resources and the number of MCS values.

[0161] It should be noted that in practical applications, the power parameter indicated by the first field and the MCS indicated by the second field in the indication information are usually presented as index values. Therefore, based on the index value of the power parameter (or MCS), the specific value of the power parameter (or MCS) can be determined, and subsequent processing can be carried out using the value of the power parameter (or MCS).

[0162] For example, suppose the indication information indicates 20 resources, and the power parameter has 4 possible values; therefore, the number of bits contained in the first field is: in, This indicates rounding up. In these 40 bits, every two bits are used to indicate the power parameter corresponding to a resource; that is, every two bits represent the index value of the power parameter corresponding to a resource. Specifically, in the 40 bits of the first field, bits 1 and 2 indicate power parameter 1 (i.e., the power parameter corresponding to resource 1), bits 3 and 4 indicate power parameter 2 (i.e., the power parameter corresponding to resource 2), ..., bits 39 and 40 indicate power parameter 20. Therefore, based on the correspondence between the index values ​​of the power parameters and their values ​​(as shown in Table 1), the value of power parameter i can be determined by its index value, i = 1, 2, ..., 20.

[0163] Table 1

[0164] Index value of power parameters Values ​​of power parameters 00 k0 01 k1 10 k2 11 k3

[0165] As shown in Table 1, if the index value of power parameter 1 is 00, then the value of power parameter 1 is k0; if the index value of power parameter 20 is 10, then the corresponding value of power parameter 20 is k2, and so on. It should be noted that the correspondence shown in Table 1 can be obtained by pre-configuring the corresponding power parameter values ​​for the index values ​​of the power parameters. Here, k0, k1, k2, and k3 are integers, for example, k0 = 2, k1 = 4, k2 = 6, k3 = 8; or, for example, k0 = -2, k1 = 2, k2 = 4, k3 = 6. Furthermore, the aforementioned correspondence can also be configured through indication information:

[0166] In one possible implementation, the indication information also includes a third field, which is used to indicate multiple values ​​of the power parameter (i.e., the value or method of taking at least one power parameter such as k0, k1, k2, k3).

[0167] For example, the third field contains 8 bits, with each 2 bits indicating one possible value for the power parameter. Since 2 bits have 4 possible values, the third field can indicate 4 possible values ​​for the power parameter, such as 2, 4, 6, and 8, or 3, 6, 9, and 12, etc. If the third field determines that the 4 possible values ​​for the power parameter are 2, 4, 6, and 8, then the corresponding power parameter values ​​are configured for the index values ​​of the power parameter. That is, in Table 1, let k0 = 2, k1 = 4, k2 = 6, and k3 = 8. If the third field determines that the 4 possible values ​​for the power parameter are 3, 6, 9, and 12, then the corresponding power parameter values ​​are configured for the index values ​​of the power parameter. That is, in Table 1, let k0 = 3, k1 = 6, k2 = 9, and k3 = 12, etc.

[0168] For example, the third field contains 2 bits, each bit indicating one value of the power parameter. Since one bit has two possible values, the third field can indicate two values ​​for the power parameter, such as 2 and 4, or 3 and 6, etc. If the two values ​​of the power parameter are determined to be 2 and 4 based on the third field, then the corresponding power parameter value is configured for the index value of the power parameter; that is, in Table 2, let k0 = 2, k1 = 4. If the two values ​​of the power parameter are determined to be 3 and 6 based on the third field, then the corresponding power parameter value is configured for the index value of the power parameter; that is, in Table 2, let k0 = 3, k1 = 6, etc. It should be understood that in this case, the number of bits contained in the first field is... In these 20 bits, each bit is used to indicate the power parameters corresponding to a resource.

[0169] Table 2

[0170] Index value of power parameters Values ​​of power parameters 0 k0 1 k1

[0171] In another possible implementation, the indication information also includes a third field, which indicates a value of the power parameter and the step size of the power parameter value. It should be noted that the step size of the power parameter value is the step size between two adjacent values ​​among the multiple possible values ​​of the power parameter.

[0172] For example, the third field contains two bits. Bit 1 indicates the first value of the power parameter, and bit 2 indicates the step size of the power parameter value. If bit 1 is 0, the first value of the power parameter is determined to be 2. If bit 2 is 0, the step size of the power parameter value is determined to be 2. Since the number of possible power parameter values ​​is 4, the first value of the power parameter can be calculated as 2, the second value as 2+2=4, the third value as 4+2=6, and the fourth value as 6+2=8. If bit 1 is 1, the first value of the power parameter is determined to be 3. If bit 2 is 1, the step size of the power parameter value is determined to be 3. Therefore, the four possible values ​​of the power parameter can be calculated as 3, 6, 9, and 12, etc. If the four possible values ​​for the power parameter are 2, 4, 6, and 8 based on the third field, then the corresponding power parameter values ​​are configured for the index values ​​of the power parameter. That is, in Table 1, let k0 = 2, k1 = 4, k2 = 6, and k3 = 8. If the four possible values ​​for the power parameter are 3, 6, 9, and 12 based on the third field, then the corresponding power parameter values ​​are configured for the index values ​​of the power parameter. That is, in Table 1, let k0 = 3, k1 = 6, k2 = 9, and k3 = 12, and so on.

[0173] It should be noted that the second field in the indication information is used for multiple MCSs, where each resource corresponds to one MCS, and at least two MCSs are different. For explanations of the MCS index value and the MCS value, please refer to the relevant explanations of the power parameters mentioned above; they will not be repeated here. The correspondence between the MCS index value and the MCS value can be configured in advance or through the indication information.

[0174] In one possible implementation, the indication information also includes a fourth field, which is used to indicate:

[0175] Multiple values ​​for MCS; or,

[0176] A value of MCS, and the step size of the MCS value.

[0177] For an explanation of the correspondence between the index value and the value of MCS, please refer to the relevant explanation section on power parameters mentioned above, which will not be repeated here.

[0178] Furthermore, after obtaining the power parameters, additional information is needed to determine the EPRE of the demodulation reference signal and the EPRE of the uplink data signal. Based on Figure 3 In the case shown, since the EPRE of all demodulation reference signals is the same, the EPRE of the same demodulation reference signal can be preset in the network device and the terminal device, or the EPRE of the same demodulation reference signal can be indicated by the indication information, which is not limited here.

[0179] based on Figure 4 In the case shown, the indication information needs to indicate the EPRE of each demodulation reference signal to determine the EPRE of each uplink data signal, or the indication information indicates the EPRE of each uplink data signal to determine the EPRE of each demodulation reference signal. These will be described separately below:

[0180] In one possible implementation, the indication information further includes a fifth field, which indicates multiple first EPREs. Each first EPRE is used to determine the EPRE of the demodulation reference signal, and one first EPRE corresponds to one resource. It should be noted that the first EPRE can be the EPRE of the demodulation reference signal. In this case, after determining the first EPRE corresponding to a resource, the EPRE of the uplink data signal corresponding to that resource can be determined based on the first EPRE and the power parameters of that resource. Alternatively, the first EPRE can be a change in the EPRE of the demodulation reference signal. In this case, after determining the first EPRE corresponding to a resource, the EPRE of the demodulation reference signal currently usable by that resource can be determined first based on the first EPRE and the EPRE of the demodulation reference signal previously used by that resource. Then, based on the EPRE of the demodulation reference signal currently usable by that resource and the power parameters of that resource, the EPRE of the uplink data signal corresponding to that resource can be determined.

[0181] It should be understood that the explanation of the index value and the value of the first EPRE can be found in the relevant explanation section of the power parameters mentioned above, and will not be repeated here. The correspondence between the index value and the value of the first EPRE can be configured in advance or through indication information:

[0182] In one possible implementation, the indication information also includes a sixth field, which is used to indicate:

[0183] Multiple values ​​for the first EPRE; or,

[0184] A value of the first EPRE, and the step size of the first EPRE value.

[0185] For example, if the first EPRE has 4 possible values, and the first value of the first EPRE is EPRE0, and the step size of the first EPRE is △EPRE, then the possible values ​​of the first EPRE are: EPRE0, EPRE0+△EPRE, EPRE0+2△EPRE, and EPRE0+3△EPRE. Another example is that the value of △EPRE is any one of {-3, -2, 2, 3}.

[0186] For an explanation of the correspondence between the index value of the first EPRE and the value of the first EPRE, please refer to the relevant explanation section on power parameters mentioned above, which will not be repeated here.

[0187] In one possible implementation, the indication information further includes a fifth field, which indicates multiple second EPREs. Each second EPRE is used to determine the EPRE of the uplink data signal, and one second EPRE corresponds to one resource. The second EPRE can be the EPRE of the uplink data signal; in this case, after determining the second EPRE corresponding to a resource, the EPRE of the demodulation reference signal corresponding to that resource can be determined based on the second EPRE and the power parameters of that resource. Alternatively, the second EPRE can be a change in the EPRE of the uplink data signal; in this case, after determining the second EPRE corresponding to a resource, the EPRE of the uplink data signal currently usable by that resource can be determined first based on the second EPRE of that resource and the EPRE of the uplink data signal previously used by that resource. Then, based on the EPRE of the uplink data signal currently usable by that resource and the power parameters of that resource, the EPRE of the demodulation reference signal corresponding to that resource can be determined.

[0188] It should be understood that the explanation of the index value and the value of the second EPRE can be found in the relevant explanation section of the power parameters mentioned above, and will not be repeated here. The correspondence between the index value and the value of the second EPRE can be configured in advance or through indication information:

[0189] In one possible implementation, the indication information also includes a sixth field, which is used to indicate:

[0190] Multiple values ​​for the second EPRE; or,

[0191] A value of the second EPRE, and the step size of the second EPRE value.

[0192] For an explanation of the correspondence between the index value of the second EPRE and the value of the second EPRE, please refer to the relevant explanation section on power parameters mentioned above, which will not be repeated here.

[0193] (ii) To reduce indication overhead, information notification can also be achieved through joint indication. Joint indication means that the indication information can be jointly indicated through a certain field, such as power parameters and MCS.

[0194] In one possible implementation, the indication information includes a first field, which indicates multiple power parameters and multiple MCSs. The size of the first field can be determined by the number of resources and the number of power parameter values, and can also be determined by the number of resources and the number of MCS values.

[0195] For example, suppose the indication information indicates 20 resources, and there are 4 possible values ​​for the power parameter and 4 possible values ​​for the MCS. Therefore, the number of bits contained in the first field is: In these 40 bits, every two bits are used to indicate the power parameter corresponding to a resource and the MCS corresponding to a resource. That is, every two bits are the index value of the power parameter and the index value of the MCS corresponding to a resource. Specifically, in the 40 bits of the first field, bits 1 and 2 are used to indicate power parameter 1 (i.e., the power parameter corresponding to resource 1) and MCS1 (i.e., the MCS corresponding to resource 1), bits 3 and 4 are used to indicate power parameter 2 and MCS2, and so on. Therefore, based on the correspondence between the index value and the value, as shown in Table 3:

[0196] Table 3

[0197] Index value of power parameter (MCS) Values ​​of power parameters The value of MCS 00 P1 MCS(1) 01 P2 MCS(2) 10 P3 MCS(3) 11 P4 MCS(4)

[0198] It should be understood that the above implementation methods can be combined with each other. For example, in Table 3, MCS(2) = MCS(1) + △MCS, MCS(3) = MCS(1) + 2△MCS, MCS(4) = MCS(1) + 3△MCS, where MCS(1) and △MCS can be determined by the indication information. Similarly, P2 = P1 + △P, P3 = P1 + 2△P, P4 = P1 + 3△P, where P1 and △P can be determined by the indication information, and so on.

[0199] As shown in Table 3, if the index value of power parameter 1 (MCS1) is 00, then the value of power parameter 1 is P1, and the value of MCS1 is MCS(1). MCS(1) can be regarded as a specific modulation and coding scheme. If the index value of power parameter 20 (MCS20) is 10, then the corresponding value of power parameter 20 is P3, and the value of MCS20 is MCS(3), etc. It should be noted that the correspondence between the index values ​​and the values ​​shown in Table 3 can be configured in advance or through indication information.

[0200] In one possible implementation, the indication information also includes a second field, which can indicate the values ​​of the power parameters and the MCS in various ways, which will be described in detail below:

[0201] In one possible implementation, if the second field is used to indicate multiple values ​​of the power parameter, then the multiple values ​​of the MCS are determined by at least one value of the power parameter.

[0202] For example, suppose the second field can determine four values ​​for the power parameter, namely 2, 4, 6, and 8. Since the first value of the power parameter is 2, the four values ​​of the MCS can be determined as MCS(1), MCS(2), MCS(3), MCS(4), and so on, based on the first value of the power parameter. Similarly, if the second field can determine the four values ​​of the MCS, then the four values ​​of the power parameter are determined by at least one of the four values ​​of the MCS, which will not be elaborated here.

[0203] In another possible implementation, if the second field is used to indicate multiple values ​​of the power parameter, then one value of the MCS and the step size of the MCS are determined by at least one value of the power parameter.

[0204] For example, suppose that the second field can determine four values ​​for the power parameter, namely 2, 4, 6, and 8. Since the first value of the power parameter is 2, the first value of MCS can be determined as MCS(1) based on the first value of the power parameter. The step size of MCS is ΔMCS. Therefore, based on MCS(1) and ΔMCS, four values ​​of MCS can be calculated, namely MCS(1), MCS(1)+ΔMCS, MCS(1)+2ΔMCS, and MCS(1)+3ΔMCS. The value of ΔMCS is any one of {-3,-2,2,3}, etc. Similarly, if the second field can determine four values ​​of MCS, then the first value of the power parameter and the step size are determined by at least one of the four values ​​of MCS, which will not be elaborated here.

[0205] In another possible implementation, if the second field is used to indicate a value of the power parameter and a step size for the power parameter, then multiple values ​​of the MCS are determined by a value of the power parameter and / or a step size for the power parameter.

[0206] For example, if the first value of the power parameter can be determined to be 2 based on the second field, and the step size of the power parameter is 2, then the four values ​​of the MCS can be determined based on the first value of the power parameter. Similarly, if the first value of the power parameter can be determined to be 3 based on the second field, and the step size of the power parameter is 3, then the four values ​​of the MCS can be determined based on the first value of the power parameter and the step size, and so on. Likewise, if the first value of the MCS and the step size of the MCS can be determined based on the second field, then the four values ​​of the power parameter can be determined through the first value of the MCS and / or the step size of the MCS.

[0207] In another possible implementation, if the second field is used to indicate a value of the power parameter and a step size for the power parameter, then a value of the MCS and a step size for the MCS are determined by the power parameter value and / or the power parameter step size.

[0208] For example, if the first value of the power parameter is 2 based on the second field, and the step size of the power parameter is 2, then the first value of the MCS and the step size of the MCS can be determined based on the first value of the power parameter. Similarly, if the first value of the power parameter is 3 based on the second field, and the step size of the power parameter is 3, then the first value of the MCS and the step size of the MCS can be determined based on the first value of the power parameter and the step size of the MCS, and so on. Likewise, if the first value of the MCS and the step size of the MCS can be determined based on the second field, then the first value of the power parameter and the step size of the MCS can be determined through the first value of the MCS and / or the step size of the MCS.

[0209] In addition, the first field of the indication information can also be used to indicate multiple first EPREs or multiple second EPREs. It should be noted that the first EPRE can be jointly indicated with power parameters and MCS, and the second EPRE can also be jointly indicated with power parameters and MCS. For details, please refer to the relevant explanation of the first field indicating multiple power parameters and multiple MCS, which will not be repeated here.

[0210] Furthermore, the second field of the indication information can also be used to indicate the value of the first EPRE or the value of the second EPRE. It should be noted that the value of the first EPRE can be jointly indicated with the value of the power parameter and the value of the MCS, and the value of the second EPRE can also be jointly indicated with the value of the power parameter and the value of the MCS. For details, please refer to the relevant explanations on the second field indicating the value of the power parameter and the value of the MCS, which will not be repeated here.

[0211] 202. The terminal device determines the uplink data signal corresponding to each resource based on at least one MCS.

[0212] Since the indication information is used to indicate at least one MCS, the terminal device can determine the MCS corresponding to each resource based on the indication information. Then, the terminal device generates the uplink data signal corresponding to each resource based on the MCS corresponding to that resource, that is, the uplink data signal that the resource needs to send.

[0213] For example, after determining that resource 1 corresponds to MCS1 and resource 2 corresponds to MCS2, the terminal device can use MCS1 to generate the uplink data signal that resource 1 needs to send, and use MCS2 to generate the uplink data signal that resource 2 needs to send, and so on.

[0214] 203. The terminal device determines the transmission power of the uplink data signal corresponding to each resource based on at least one power parameter.

[0215] Since the indication information is used to indicate at least one power parameter, the terminal device can determine the power parameter corresponding to each resource based on the indication information. Then, the terminal device can determine the transmission power corresponding to each resource based on the power parameter corresponding to each resource, that is, the transmission power of the demodulation reference signal corresponding to the resource and the transmission power of the uplink data signal corresponding to the resource.

[0216] Specifically, the terminal device can determine the transmission power corresponding to each resource in a variety of ways:

[0217] In one possible implementation, if the transmission power of the demodulation reference signal corresponding to all resources is the same, the terminal device can determine the transmission power of the uplink data signal corresponding to each resource based on the power parameter corresponding to each resource and the transmission power of the same demodulation reference signal.

[0218] For example, the transmission power of the demodulation reference signal corresponding to all resources is set to the same preset value (or, the transmission power of the demodulation reference signal is determined according to the preset relevant parameters and methods for determining the transmission power of the demodulation reference signal). After determining the power parameter corresponding to a certain resource, the terminal device can calculate the transmission power of the uplink data signal corresponding to that resource based on the power parameter corresponding to that resource and the aforementioned preset value.

[0219] In another possible implementation, the terminal device can determine the transmission power corresponding to each resource based on the power parameters corresponding to each resource and the first EPRE corresponding to each resource.

[0220] For example, when a terminal device determines the power parameters and the first EPRE corresponding to a certain resource, it can calculate the transmission power of the demodulation reference signal and the transmission power of the uplink data signal corresponding to the resource based on the power parameters and the first EPRE corresponding to the resource.

[0221] In another possible implementation, the terminal device can determine the transmission power corresponding to each resource based on the power parameters corresponding to each resource and the second EPRE corresponding to each resource.

[0222] For example, when a terminal device determines the power parameters and the second EPRE corresponding to a certain resource, it can calculate the transmission power of the demodulation reference signal and the transmission power of the uplink data signal corresponding to the resource based on the power parameters and the second EPRE corresponding to the resource.

[0223] It should be understood that steps 202 and 203 can be executed simultaneously or sequentially. When they are executed sequentially, step 202 can be executed first and then step 203, or step 203 can be executed first and then step 202; there is no limitation here.

[0224] 204. The terminal device sends uplink data signals to the network device on the corresponding resource based on the transmission power of the uplink data signal corresponding to each resource and the uplink data signal corresponding to each resource.

[0225] After determining the transmission power and uplink data signal corresponding to each resource, the terminal device sends a demodulation reference signal and an uplink data signal to the network device on the corresponding resource. The demodulation reference signal is used to demodulate the uplink data signal. It should be noted that the demodulation reference signal sent by the terminal device on a certain resource is used to obtain the channel of the propagation channel on that resource, thereby facilitating the demodulation of the uplink data signal sent on that resource.

[0226] For example, the terminal device can use the transmission power corresponding to resource 1 (including the transmission power of the demodulation reference signal and the transmission power of the uplink data signal corresponding to resource 1) to transmit the demodulation reference signal and the uplink data signal generated based on MCS1 to the network device on resource 1. The demodulation reference signal transmitted by the terminal device on resource 1 is used to demodulate the uplink data signal generated based on MCS1. The terminal device can also use the transmission power corresponding to resource 2 to transmit the demodulation reference signal and the uplink data signal generated based on MCS2 to the network device on resource 2. The demodulation reference signal transmitted by the terminal device on resource 2 is used to demodulate the uplink data signal generated based on MCS2, and so on.

[0227] After the terminal device sends signals to the network device through different resources, the network device can receive the demodulation reference signal and uplink data signal from the terminal device on the corresponding resource based on the MCS and power parameters of each resource, thereby completing uplink scheduling.

[0228] Specifically, if the EPRE of the demodulation reference signals corresponding to all resources is the same (i.e., the transmission power of the demodulation reference signals corresponding to all resources is the same), then the network device can receive the demodulation reference signal and uplink data signal from the terminal device on that resource based on the MCS corresponding to that resource and the power parameters of that resource. For example, the terminal device can receive the demodulation reference signal and the uplink data signal generated based on MCS1 on resource 1 based on MCS1 and power parameter 1. The network device can also receive the demodulation reference signal and the uplink data signal generated based on MCS2 on resource 2 based on MCS2 and power parameter 2, and so on.

[0229] If, among multiple resources, at least two resources have different EPREs for their demodulation reference signals (i.e., at least two resources have different transmission powers for their demodulation reference signals), then the network device can receive the demodulation reference signal and downlink data signal from the terminal device on that resource based on the MCS corresponding to that resource, the first EPRE corresponding to that resource, and the power parameter corresponding to that resource. For example, the network device can receive the demodulation reference signal and the uplink data signal generated based on MCS1 on resource 1 based on MCS1, the first EPRE1, and power parameter 1. Similarly, the network device can receive the demodulation reference signal and the uplink data signal generated based on MCS2 on resource 2 based on MCS2, the first EPRE2, and power parameter 2, and so on.

[0230] In the second scenario described above, the terminal device can also receive demodulation reference signals and downlink data signals on a resource based on the MCS corresponding to that resource, the second EPRE corresponding to that resource, and the power parameters corresponding to that resource. For example, the network device can receive demodulation reference signals and uplink data signals generated based on MCS1 on resource 1 based on MCS1, the second EPRE1, and power parameter 1. Similarly, the network device can receive demodulation reference signals and uplink data signals generated based on MCS2 on resource 2 based on MCS2, the second EPRE2, and power parameter 2, and so on.

[0231] In this embodiment, the terminal device first receives indication information from the network device. This indication information specifies multiple resources for transmitting uplink data signals, at least one modulation and coding scheme (MCS), and at least one power parameter. Then, the terminal device determines the MCS and power parameter corresponding to each resource based on the indication information. Next, the terminal device determines the uplink data signal corresponding to each resource based on its MCS and the transmission power corresponding to each resource based on its power parameter, thereby transmitting the uplink data signal to the network device on the corresponding resource. In this process, the network device can indicate at least one MCS and at least one power parameter to the terminal device through the indication information. This allows the terminal device to transmit data signals to the network device using different MCS and / or different transmission powers on different resources based on the indication information, thereby improving the data signal transmission quality and ensuring that the network device can accurately receive the data signal.

[0232] Figure 5 For another flowchart illustrating the signal transmission method provided in this application embodiment, please refer to [link / reference]. Figure 5 The method includes:

[0233] 501. The terminal device receives instruction information from the network device.

[0234] In downlink scheduling, network devices may first send indication information to terminal devices, which indicates: multiple resources for transmitting downlink data signals, at least one MCS, and at least one power parameter.

[0235] It should be noted that for explanations of indication information, resources, MCS, and power parameters, please refer to the relevant explanations in step 201 above, which will not be repeated here.

[0236] 502. Network devices can determine the downlink data signal corresponding to each resource based on at least one MCS.

[0237] 503. The network device determines the transmission power of the downlink data signal corresponding to each resource based on at least one power parameter.

[0238] It should be understood that steps 502 and 503 can be executed simultaneously or sequentially. When they are executed sequentially, step 502 can be executed first and then step 503, or step 503 can be executed first and then step 502; there is no limitation here.

[0239] 504. The network device sends downlink data signals to the terminal device on the corresponding resource based on the transmission power of the downlink data signal corresponding to each resource and the downlink data signal corresponding to each resource.

[0240] For an explanation of steps 502 to 504, please refer to the relevant explanations of steps 202 to 204 above, which will not be repeated here.

[0241] It should be noted that the difference between the two is as follows: In steps 202 to 204, the terminal device is the data signal transmitter and the network device is the data signal receiver. However, in steps 502 to 504, the terminal device is the data signal receiver and the network device is the data signal transmitter.

[0242] After the network device sends demodulation reference signals and downlink data signals to the terminal device through different resources, the terminal device can receive the demodulation reference signals and downlink data signals from the terminal device on the corresponding resource based on the MCS corresponding to each resource and the power parameters corresponding to each resource, thereby completing downlink scheduling.

[0243] Specifically, if the EPRE of the demodulation reference signals corresponding to all resources is the same (i.e., the transmission power of the demodulation reference signals corresponding to all resources is the same) and is the same preset value, then the indication information sent to the terminal device does not need to indicate the EPRE of the signal or its value, which helps to reduce indication overhead. In this case, the terminal device can receive the demodulation reference signal and downlink data signal from the network device on a resource based on the MCS corresponding to that resource and the power parameters (e.g., power ratio or power difference) of that resource. For example, the terminal device can receive the demodulation reference signal and the downlink data signal generated based on MCS1 on resource 1 based on MCS1 and power parameter 1, wherein the demodulation reference signal transmitted on resource 1 is used to demodulate the downlink data signal generated based on MCS1. The terminal device can also receive the demodulation reference signal and the downlink data signal generated based on MCS2 on resource 2 based on MCS2 and power parameter 2, wherein the demodulation reference signal transmitted on resource 2 is used to demodulate the downlink data signal generated based on MCS2, and so on.

[0244] If, among multiple resources, at least two resources have different EPREs for their demodulation reference signals (i.e., at least two resources have different transmission powers for their demodulation reference signals), then the indication information sent to the terminal device needs to indicate the first EPRE for each resource (the first EPRE can be the EPRE of the demodulation reference signal or a variation of the EPRE of the demodulation reference signal) and multiple possible values ​​for the first EPRE. In this case, the terminal device can receive the demodulation reference signal and downlink data signal from the terminal device on that resource based on the MCS corresponding to that resource, the first EPRE corresponding to that resource, and the power parameter corresponding to that resource. For example, the terminal device can receive the demodulation reference signal and the downlink data signal generated based on MCS1 on resource 1 based on MCS1, the first EPRE1, and power parameter 1. The terminal device can also receive the demodulation reference signal and the downlink data signal generated based on MCS2 on resource 2 based on MCS2, the first EPRE2, and power parameter 2, and so on.

[0245] In the second scenario described above, the instruction information sent to the terminal device may also indicate the second EPRE corresponding to each resource (the second EPRE can be the EPRE of the downlink data signal or a change in the EPRE of the downlink data signal) and multiple values ​​of the second EPRE. Then, based on the MCS corresponding to a resource, the second EPRE corresponding to that resource, and the power parameter corresponding to that resource, the terminal device can receive the demodulation reference signal and the downlink data signal from the terminal device on that resource. For example, the terminal device can receive the demodulation reference signal and the downlink data signal generated based on MCS1 on resource 1 based on MCS1, second EPRE1, and power parameter 1. Similarly, the terminal device can receive the demodulation reference signal and the downlink data signal generated based on MCS2 on resource 2 based on MCS2, second EPRE2, and power parameter 2, and so on.

[0246] In this embodiment, the network device can indicate at least one MCS and at least one power parameter to the terminal device via indication information. Then, based on the indication information, the network device transmits data signals to the terminal device using different MCS and / or different transmit powers on different resources, thereby improving the transmission quality of the data signals and ensuring that the terminal device can accurately receive the data signals.

[0247] It should be understood that, Figure 2 The illustrated embodiments and Figure 5Prior to the illustrated embodiment, further information interaction can be achieved between the terminal device and the network device. This information interaction is used to enable the terminal device and / or the network device to perform data transmission using multiple MCSs and / or multiple transmit powers on multiple resources, and to use this function. For example, the terminal device first sends a function request message to the network device (this message is used to request whether the function can be enabled). Based on the function request message, after determining that the terminal device can enable the function at an appropriate time, the network device sends a request response message to the terminal device, so that the terminal device enables the function based on the request response message, thereby enabling the terminal device to transmit data signals using multiple MCSs and / or multiple transmit powers on multiple resources. Furthermore, the function request information and / or request response information may include at least one of the following information (or constraints): the maximum allowed MCS, the minimum allowed MCS, the maximum difference between the maximum and minimum allowed MCS, the maximum difference between the maximum allowed transmit power and the minimum transmit rate (of the demodulation reference signal or data signal), the maximum allowed ratio between the EPRE of the demodulation reference signal and the EPRE of the data signal, the minimum allowed ratio between the EPRE of the demodulation reference signal and the EPRE of the data signal, the maximum allowed ratio between the EPRE of the demodulation reference signal and the average EPRE of the demodulation reference signal (which can be understood as the average value between the EPREs of the various demodulation reference signals), the minimum allowed ratio between the EPRE of the demodulation reference signal and the average EPRE of the data signal, the maximum allowed ratio between the EPRE of the data signal and the EPRE of the demodulation reference signal, the minimum allowed ratio between the EPRE of the data signal and the EPRE of the demodulation reference signal, the maximum allowed ratio between the EPRE of the data signal and the average EPRE of the demodulation reference signal, and the minimum allowed ratio between the EPRE of the data signal and the average EPRE of the demodulation reference signal.

[0248] It should also be understood that further constraints may be imposed on the multiple power parameters and multiple MCSs in this invention. For example, the difference between the maximum and minimum transmit power corresponding to multiple power parameters shall not exceed X dB; for another example, the difference between the maximum and minimum MCS shall not exceed Y; for another example, all MCSs correspond to the same modulation order Q, and multiple MCSs correspond to multiple channel coding rates; for another example, the difference X between the maximum transmit powers is related to the modulation order Q. For another example, X may be 20 dB when Q=1; 10 dB when Q=2; 6 dB when Q=4; 4 dB when Q=6; and 2 dB when Q=8; for another example, X may be 10 dB when Q=1 or Q=2; 15 dB when Q=4 or Q=6; and 20 dB when Q=8.

[0249] It should also be understood that multiple MCS and / or multiple power parameters are allowed for data transmission only when the number of resources used by network devices and terminal devices for data transmission exceeds a threshold F (e.g., the bandwidth used for data transmission in a single time slot is greater than F RBs or RBGs), such as F>20; or F=32.

[0250] It should also be understood that various information in all the foregoing embodiments (e.g., multiple MCSs, multiple power parameters, the values ​​of MCSs, the values ​​of power parameters, etc.) can be indicated by at least one of DCI, RRC, and MAC-CE. For example, DCI can be used to indicate all information. Alternatively, RRC can be used to indicate a portion of the information, and MAC-CE can be used to indicate the remaining information. Yet another example is that RRC can be used to indicate a portion of the information, and DCI can be used to indicate the remaining information. Still another example is that RRC can be used to indicate a portion of the information, MAC-CE can indicate another portion of the information, and DCI can be used to indicate the remaining information. No limitations are made in this application.

[0251] It should also be understood that the various alternative embodiments in this application can be used in any combination.

[0252] In the embodiments of this application, the antenna and radio frequency circuit with transceiver function can be regarded as the transceiver unit of the terminal, and the processor with processing function can be regarded as the processing unit of the terminal. Figure 6 A schematic diagram of the structure of a terminal device provided in an embodiment of this application, as shown below. Figure 6 As shown, the terminal device includes a transceiver unit and a processing unit 602. The transceiver unit can also be called a transceiver, transceiver machine, transceiver device, etc. The processing unit can also be called a processor, processing board, processing module, processing device, etc. Optionally, the device in the transceiver unit used to implement the receiving function can be considered as a receiving unit 601, and the device in the transceiver unit used to implement the transmitting function can be considered as a transmitting unit 603; that is, the transceiver unit includes a receiving unit 601 and a transmitting unit 603. The transceiver unit can sometimes also be called a transceiver machine, transceiver, or transceiver circuit, etc. The receiving unit 601 can sometimes be called a receiver, receiver, or receiving circuit, etc. The transmitting unit 603 can sometimes be called a transmitter, transmitter, or transmitting circuit, etc. It should be understood that the transceiver unit is used to perform... Figure 2 In the illustrated embodiment, the processing unit 602 is used to execute the sending and receiving operations of the terminal device. Figure 2 The embodiments shown describe operations other than sending and receiving on the terminal device.

[0253] Specifically, the receiving unit 601 is used to receive indication information from the network device, the indication information indicating: multiple resources for transmitting uplink data signals, at least one modulation and coding scheme (MCS), and at least one power parameter.

[0254] Processing unit 602 is used to determine the uplink data signal corresponding to each resource based on at least one MCS;

[0255] The processing unit 602 is further configured to determine the transmission power of the uplink data signal corresponding to each resource based on at least one power parameter;

[0256] The transmitting unit 603 is used to transmit uplink data signals to the network device on the corresponding resource according to the transmission power of the uplink data signal corresponding to each resource and the uplink data signal corresponding to each resource.

[0257] In one possible implementation, the indication information is used to indicate multiple power parameters, wherein each resource corresponds to one power parameter, and at least two power parameters are different.

[0258] In one possible implementation, the transmission power of the demodulation reference signal corresponding to each resource is the same, and the transmission power of the uplink data signal corresponding to at least two resources is different.

[0259] In one possible implementation, the indication information is used to indicate multiple MCSs, wherein each resource corresponds to one MCS, and at least two MCSs are different.

[0260] In one possible implementation, different resources correspond to different frequency domain resource locations among multiple resources.

[0261] In one possible implementation, the larger the MCS corresponding to a resource, the greater the transmission power of the uplink data signal corresponding to that resource.

[0262] In one possible implementation, the power parameter can be: the ratio between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal; or, the difference between the transmission power of the demodulation reference signal and the transmission power of the uplink data signal.

[0263] In one possible implementation, the indication information includes a first field and a second field. The first field indicates multiple power parameters, and the second field indicates multiple MCSs. The size of the first field is determined based on the number of resources and the number of possible power parameter values, and the size of the second field is determined based on the number of resources and the number of possible MCS values.

[0264] In one possible implementation, the indication information also includes a third field, which indicates: multiple values ​​of the power parameter; or, one value of the power parameter, and the step size of the power parameter value. It should be noted that the step size of the power parameter value is the step size between two adjacent values ​​among the multiple values ​​of the power parameter.

[0265] In one possible implementation, the indication information also includes a fourth field, which indicates: multiple values ​​of MCS; or, one value of MCS, and the value step size of MCS. It should be noted that the value step size of MCS is the step size between two adjacent values ​​among the multiple values ​​of MCS.

[0266] In one possible implementation, the indication information further includes a fifth field, which indicates a plurality of first EPREs, which are used to determine the EPRE of the demodulation reference signal, and one first EPRE corresponds to one resource.

[0267] In one possible implementation, the indication information further includes a sixth field, which indicates: multiple values ​​of the first EPRE; or, one value of the first EPRE, and the step size of the first EPRE value. It should be noted that the step size of the first EPRE value is the step size between two adjacent values ​​among the multiple values ​​of the first EPRE.

[0268] In one possible implementation, the indication information also includes a fifth field, which indicates multiple second EPREs, which are used to determine the EPRE of the uplink data signal, and one second EPRE corresponds to one resource.
