[0053] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0054] Figure 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. As shown in Figure 1, communication system 100 may include terminal device 110 and network device 120. Network device 120 may communicate with terminal device 110 via an air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

[0055] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0056] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0057] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0058] The terminal device 110 can be used for device-to-device (D2D) communication.

[0059] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0060] Figure 1 exemplarily shows a base station, a core network device and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0061] It should be noted that FIG1 is only an example of a system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this article.

[0062] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0063] Data and pilot superimposed transmission

[0064] In order to reduce the overhead of DMRS and increase the transmission rate, it is possible to consider superimposing DMRS and data for transmission. As shown in Figure 2, resource element (RE) 201 is used for the control channel, and RE202 is used for data and DMRS. In this method, DMRS and data occupy the same physical resources and are superimposed and transmitted using a certain transmit power ratio (i.e., DMRS and data signals are superimposed on the same RE for transmission, where RE is the smallest resource unit for signal transmission). At the receiving end, the artificial intelligence (AI) receiver can directly detect the data without the need for a separate channel estimation process. In Figure 2, all REs used to transmit data can be used to send DMRS at the same time, so that no dedicated resources are required to send DMRS, which significantly reduces resource overhead.

[0065] Uplink Physical Uplink Shared Channel (PUSCH) power control

[0066] Currently, the transmit power of PUSCH can be calculated using formula (1):

[0067] Among them, P CMAX,f,c (i) is the maximum transmit power supported by the terminal on carrier f in serving cell c, i is the index of a PUSCH transmission, and j is the open-loop power control parameter index (including the target power P O_PUSCH,b,f,c (j) and path loss factor α b,f,c (j));q d It is the index of the reference signal used for path loss measurement, used to obtain the path loss value PL b,f,c (q d ), which is also an open-loop power control parameter; f b,f,c (i, l) is the closed-loop power control adjustment factor, where l is the closed-loop power control process.

[0068] Among them, the terminal device determines the closed-loop power adjustment factor based on the transmit power control (TPC) command sent by the network side. The TPC command can be carried by the downlink control information (DCI) used to schedule the PUSCH in the UE search space, or by the DCI format (format) 2_2 used to carry the group TPC command in the common search space.

[0069] In NR, the terminal device determines the transmit beam of the scheduled PUSCH based on the Sounding Reference Signal (SRS) Resource Indicator (SRI) in the DCI, and also determines the power control parameters used by the PUSCH based on the SRI. Specifically, the network side pre-configures multiple SRI-PUSCH-Power Control (PowerControl) parameter fields through Radio Resource Control (RRC) signaling. Each parameter field corresponds to an SRI value, and the parameter field contains a set of PUSCH power control parameter configurations corresponding to the SRI value (for example, j, q d , 1, etc.). When the value indicated by the SRI is different, the power control parameter configuration in the corresponding parameter field (SRI-PUSCH-PowerControl) is used to determine the transmit power of the currently scheduled PUSCH.

[0070] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0071] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG3 , including:

[0072] S301. The terminal device determines a first physical resource and a second physical resource, where the first physical resource is used to transmit an uplink reference signal, the second physical resource is used to transmit an uplink channel, and the first physical resource is part of the second physical resource.

[0074] S303. The terminal device sends the uplink reference signal on the first physical resource based on the transmission power of the uplink reference signal, and sends the uplink channel on the second physical resource based on the transmission power of the uplink channel.

[0075] An embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG4 , including:

[0076] S401. A network device sends first configuration information, where the first configuration information is used to configure a first physical resource and a second physical resource. The first physical resource is used to transmit an uplink reference signal, the second physical resource is used to transmit an uplink channel, and the first physical resource is part of the second physical resource.

[0077] S402: The network device receives the uplink reference signal on the first physical resource, and receives the uplink channel on the second physical resource.

[0078] An embodiment of the present application provides a wireless communication method, which is applied to a communication system including a terminal device and a network device, as shown in FIG5 , including:

[0079] S501. A network device sends first configuration information to a terminal device. The first configuration information is used to configure a first physical resource and a second physical resource. The first physical resource is used to transmit an uplink reference signal, the second physical resource is used to transmit an uplink channel, and the first physical resource is part of the second physical resource.

[0080] S502. The terminal device determines a first physical resource and a second physical resource based on the first configuration information.

[0081] S503. The terminal device determines the transmit power of the uplink reference signal and the transmit power of the uplink channel;

[0082] S504. The terminal device sends the uplink reference signal on the first physical resource based on the transmission power of the uplink reference signal, and sends the uplink channel on the second physical resource based on the transmission power of the uplink channel.

[0083] Next, the wireless communication method shown in FIG. 3 , FIG. 4 or FIG. 5 will be described.

[0084] The network device sends first configuration information to the terminal device, where the first configuration information is used to configure a first physical resource and a second physical resource. The first physical resource is used to transmit an uplink reference signal of the terminal device, and the second physical resource is used to transmit an uplink channel of the terminal device.

[0085] The terminal device determines the first physical resource and the second physical resource based on the first configuration information sent by the network device.

[0086] Optionally, the network device may indicate the first physical resource and the second physical resource through physical layer signaling or higher layer signaling.

[0087] In one example, the network device indicates the first physical resource of the terminal device from multiple first physical resources through DCI.

[0088] Uplink reference signals include but are not limited to DMRS, SRS, Phase Tracking Reference Signal (PTRS) and other signals.

[0089] The uplink channel may be an uplink channel for carrying uplink data, such as a PUSCH, or may be an uplink channel for carrying uplink control information, such as a physical uplink control channel (PUCCH).

[0090] In an embodiment of the present application, the first physical resource is part of the second physical resource, and the first physical resource is used to transmit both the uplink reference signal and the uplink channel, and the other physical resources in the second physical resource except the first physical resource are only used to transmit the uplink channel.

[0091] In the embodiment of the present application, the physical resource is also called the time-frequency resource, which is a two-dimensional resource region of time and frequency composed of the smallest time-frequency resource unit, the resource element (RE). The second physical resource can include multiple time-domain resources (such as OFDM symbols or time slots) in the time domain and multiple frequency-domain resources (such as physical resource blocks (PRBs) or subcarriers) in the frequency domain. For example, it can be several symbols in the time domain and several PRBs in the frequency domain.

[0092] The first physical resource may occupy part of the time domain resources and / or part of the frequency domain resources of the second physical resource.

[0093] In one example, the first physical resource occupies all frequency domain resources on part of the time domain resources of the second physical resource.

[0094] For example, as shown in Figure 6, the second physical resource includes 14 symbols in the time domain and 12 subcarriers in the frequency domain. The first physical resource occupies 2 symbols of the second physical resource in the time domain and occupies 12 subcarriers of the second physical resource in the frequency domain.

[0095] It should be noted that in the embodiment of the present application, 601 identifies the RE of the uplink channel, and 602 identifies the RE for transmitting the uplink reference channel and the uplink channel.

[0096] In one example, the first physical resource occupies part of the frequency domain resources of the entire time domain resources of the second physical resource.

[0097] For example, as shown in Figure 7, the second physical resource includes 14 symbols in the time domain and 12 subcarriers in the frequency domain. The first physical resource occupies 14 symbols of the second physical resource in the time domain and occupies 2 subcarriers of the second physical resource in the frequency domain.

[0098] In one example, the first physical resource occupies part of the time domain resources and part of the frequency domain resources of the second physical resource.

[0099] For example, as shown in Figure 8, the second physical resource includes 14 symbols in the time domain and 12 subcarriers in the frequency domain. The first physical resource occupies 4 symbols of the second physical resource in the time domain and 2 subcarriers of the second physical resource in the frequency domain.

[0100] For example, as shown in Figure 9, the second physical resource includes 14 symbols in the time domain and 12 subcarriers in the frequency domain. The first physical resource occupies 1 symbol of the second physical resource in the time domain and 2 subcarriers of the second physical resource in the frequency domain.

[0101] For example, as shown in Figure 10, the second physical resource includes 14 symbols in the time domain and 12 subcarriers in the frequency domain. The first physical resource occupies 4 symbols of the second physical resource in the time domain and occupies 1 subcarrier of the second physical resource in the frequency domain.

[0102] It should be noted that the network device may schedule one or more terminal devices for multiplexing on the second physical resource, that is, the second physical resource is used to transmit the uplink channels of one or more terminal devices. The terminal device in Figure 3, Figure 4, or Figure 5 may be any of the one or more terminal devices scheduled on the second physical resource.

[0103] The second physical resource is scheduled for multiple terminal devices, and the first physical resource used for transmitting the uplink reference signal of each terminal device among the multiple terminal devices is part of the second physical resource, and the first physical resources of different terminal devices occupy different REs in the second physical resource.

[0104] In one example, the second physical resource is used for the uplink channel of the first terminal device and the second terminal device, the first physical resource of the first terminal device is part of the second physical resource, the first physical resource of the second terminal device is part of the second physical resource, and the first physical resource of the first terminal device and the first physical resource of the second terminal device occupy different REs in the second physical resource.

[0105] In the embodiment of the present application, the first physical resources of different terminal devices occupy different REs of the second physical resources, which may include but is not limited to one of the following:

[0106] Occupancy situation 1: each first physical resource occupies a different subcarrier;

[0107] Occupancy situation 2: each first physical resource occupies a different OFDM symbol;

[0108] Occupancy situation 3: each first physical resource occupies 6 subcarriers on one OFDM symbol;

[0109] Occupancy scenario 4: each first physical resource occupies 1 subcarrier on 6 or 7 OFDM symbols.

[0110] Occupancy situation 5: Each first physical resource occupies a number of subcarriers on two OFDM symbols. The two OFDM symbols may be continuous or discontinuous.

[0111] For occupancy case 3, a physical resource block (PRB) including 14 OFDM symbols in the time domain and 12 subcarriers in the frequency domain can support up to 24 or 28 first physical resources, where two symbols of one PRB can be used for the control channel, and the two symbols are not used for the first physical resources and the second physical resources.

[0112] In an embodiment of the present application, the network device indicates the first physical resource of each terminal device from the first physical resources of multiple terminal devices through DCI.

[0113] The terminal device determines the transmission power of the uplink reference signal and the transmission power of the uplink channel, sends the uplink reference signal on the first physical resource based on the transmission power of the uplink reference signal, and sends the uplink channel on the second physical resource based on the transmission power of the uplink channel.

[0114] The network device receives an uplink reference signal of the terminal device on the first physical resource, and receives an uplink channel of the terminal device on the second physical resource.

[0115] If the second physical resource is multiplexed with multiple terminal devices, an uplink channel is transmitted for each terminal device on the second physical resource, and an uplink reference signal is transmitted for that terminal device on the first physical resource. The network device receives uplink channels from the multiple terminal devices on the second physical resource, and receives an uplink reference signal for each terminal device on the first physical resource.

[0116] In some embodiments, the network device uses the signal received on the second physical resource as the input of the AI ​​model, thereby outputting the data bits carried by the uplink channel of the terminal device. The input of the AI ​​model may also include a sequence of uplink reference signals. In this case, the network device can train the uplink reference signal of each terminal device separately to obtain a corresponding model for signal detection of the terminal device.

[0117] Optionally, if the second physical resource simultaneously carries uplink channels of multiple terminal devices, the AI ​​model can simultaneously output data bits of each of the multiple terminal devices. The input of the AI ​​model can also include a sequence of uplink reference signals of each of the multiple terminal devices.

[0118] In the wireless communication method provided in the embodiment of the present application, the first physical resource for transmitting the uplink reference signal is part of the second physical resource for transmitting the uplink channel, so that the uplink reference signal is superimposed and transmitted on the uplink channel on part of the second physical resource. Therefore, when multiple terminal devices perform MU-MIMO, different reference signal resources and data superposition can be used to reduce interference on the reference signal.

[0119] In some embodiments, the terminal device determines the transmit power of the uplink reference signal and the transmit power of the uplink channel at S302, including:

[0120] The terminal device determines the transmission power of the uplink reference signal and the transmission power of the uplink channel based on a first power ratio, where the first power ratio is the ratio between the transmission power of the uplink reference signal and the transmission power of the uplink channel.

[0121] It can be understood that if the uplink channel carries multiple transmission layers, the first power ratio is the ratio between the transmission power of the uplink reference signal corresponding to each layer of data and the transmission power of each layer of data (that is, the ratio is per layer), or the first power ratio is the ratio between the transmission power of the uplink reference signal corresponding to each layer of data and the sum of the transmission powers of all data transmission layers.

[0122] It should be noted that the first power ratio here is the ratio between the transmission power of the uplink reference signal and the transmission power of the uplink channel. It can be understood that the first power ratio can also be the ratio between the transmission power of the uplink channel and the transmission power of the uplink reference signal. The description method is different, and the actual effect is the same.

[0123] In some embodiments, the first power ratio is one of the following:

[0124] Definition 1: A ratio between the transmit power of the uplink reference signal and the transmit power of the uplink channel in the first physical resource;

[0125] Definition 2: A ratio between the total transmit power of the uplink reference signal and the total transmit power of the uplink channel in a first time domain resource, where the first time domain resource is the time domain resource where the uplink reference signal is located.

[0126] Definition 3: Ratio of the transmit power of the uplink reference signal on each resource element RE to the transmit power of the uplink channel on each resource element RE in the first time domain resource;

[0127] Definition 4: In the second physical resource, the ratio of the transmit power of the uplink reference signal on each RE to the transmit power of the uplink channel on each RE.

[0128] In the embodiment of the present application, the transmit power of the uplink reference signal on each RE is also called the energy per RE (Energy Per Resource Element, EPRE) of the uplink reference signal, and the transmit power of the uplink channel on each RE is also called the EPRE of the uplink channel.

[0129] Definition 3 may be a ratio between the EPRE of the uplink reference signal and the EPRE of the uplink channel in the first time domain resource;

[0130] Definition 1 may be a ratio between the EPRE of the uplink reference signal and the EPRE of the uplink channel in the first physical resource.

[0131] Definition 4 can be described as the ratio between the EPRE of the uplink reference signal and the EPRE of the uplink channel.

[0132] It should be noted that in the above definitions, the order of the uplink reference signal and the uplink channel can be swapped (for example, Definition 1 is the ratio between the transmission power of the uplink channel and the uplink reference signal in the first physical resource), which does not affect the actual effect of the present invention, but the description method is different.

[0133] In some embodiments, if the first power ratio is defined as Definition 1, the method for determining the transmit power of the uplink reference signal and the transmit power of the uplink channel includes Method 1:

[0134] Allocate a first transmit power to the second physical resource; and allocate the uplink transmit power allocated to the first physical resource to the uplink reference signal and the uplink channel according to the first power ratio.

[0135] Specifically, the terminal device evenly distributes the first transmission power to the second physical resource; and then distributes the uplink transmission power allocated to the first physical resource to the uplink reference signal and uplink channel in the first physical resource according to the first power ratio.

[0136] In method 1, the transmit power on different REs of the second physical resource is the same, wherein the power of the REs on the first physical resource is divided into the uplink reference signal and the uplink channel, and the transmit power on other REs in the second physical resource that are only used for the uplink channel is only used for uplink channel transmission.

[0137] In one example, assuming that the transmission power allocated to each RE is 1 and the first power ratio is 0.4:0.6, then on the RE of the first physical resource, the transmission power of the uplink reference signal and the uplink channel are 0.4 and 0.6 respectively; on other REs of the second physical resource, the transmission power of the uplink channel is 1.

[0138] It is understandable that if the uplink channel carries multiple transmission layers, the transmission power of the uplink channel needs to be evenly distributed to each transmission layer.

[0139] In method 1 of the embodiment of the present application, the superimposed transmission of the uplink reference signal and the uplink channel will only affect the transmission power of the uplink channel on the first physical resource, and the uplink channels on other physical resources will not be affected, thereby minimizing the impact of the superimposed transmission on the transmission performance of the uplink channel.

[0140] In some embodiments, if the first power ratio is defined as Definition 2, the method for determining the transmit power of the uplink reference signal and the transmit power of the uplink channel includes Method 2:

[0141] Allocating, on the first time domain resource, a first transmit power to the uplink reference signal and the uplink channel according to the first power ratio;

[0142] The first transmit power is allocated to the uplink channel on a second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0143] The terminal device allocates the first transmission power to the uplink reference signal and the uplink channel according to the first power ratio on the first time domain resource, thereby obtaining the transmission power of the uplink reference signal and the uplink channel on the first time domain resource.

[0144] The terminal device can allocate the transmission power of the uplink reference signal to each RE that transmits the uplink reference signal in the first time domain resource.

[0145] The transmission power of the uplink channel is distributed to each RE that transmits the uplink channel in the first time domain resource.

[0146] In one example, assuming that the uplink transmission power is 23dBm, i.e. 200mW, and the first power ratio is 1, the transmission power of the uplink reference signal and the uplink channel in the first time domain resource are respectively 20dBm, i.e. 100mW, and the terminal device evenly distributes these powers to each RE that transmits them.

[0147] It should be noted that if the first time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power can be determined according to this method on each time domain resource unit of the first time domain resource.

[0148] In method 2, on the time domain resource that does not include the uplink reference signal in the second physical resource, i.e., the second time domain resource, the terminal device allocates the first transmit power to the uplink channel. That is, on the second time domain resource, the terminal device directly uses the first transmit power for the transmission of the uplink channel.

[0149] In method 2 of the embodiment of the present application, the transmit power on the second time domain resource is not affected, but the transmit power of the uplink channel on different time domain resources is different (the transmit power of the uplink channel on the first time domain resource is lower than the transmit power of the uplink channel on the second time domain resource), which places higher requirements on the detection at the receiving end. At the same time, compared to method 1, the power loss of the uplink channel on the first time domain resource is less (the power of the reference signal is distributed across the uplink channels of all frequency domain resources), thereby ensuring data detection performance.

[0150] In some embodiments, if the first power ratio is defined as Definition 2, the method for determining the transmit power of the uplink reference signal and the transmit power of the uplink channel includes Method 3:

[0151] Allocating, on the first time domain resource, a first transmit power to the uplink reference signal and the uplink channel according to the first power ratio;

[0152] The transmission power of the RE of the uplink channel on the first time domain resource is used for the RE of the uplink channel on the second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0153] Specifically, the terminal device allocates the first transmission power to the uplink reference signal and the uplink channel according to the first power ratio on the first time domain resource, thereby obtaining the transmission power of the uplink reference signal and the uplink channel on the first time domain resource.

[0154] The terminal device may distribute the transmission power of the uplink reference signal to each RE that transmits the uplink reference signal in the first time domain resource, and distribute the transmission power of the uplink channel to each RE that transmits the uplink channel in the first time domain resource.

[0155] In method 3, the transmission power of each RE allocated to the uplink channel on the first time domain resource is used for each RE of the uplink channel on the second time domain resource, that is, the power of REs transmitting the uplink channel on different time domain resources is the same.

[0156] It should be noted that, in the case where the uplink channel occupies all subcarriers of a symbol on the first time domain resource, the transmit power of the RE allocated to the uplink channel on the first time domain resource is used for the RE of the uplink channel on the second time domain resource. This can also be described as: the transmit power allocated to the uplink channel on the first time domain resource is used for the transmission of the uplink channel on the second time domain resource, that is, the transmit power allocated to the uplink channel on the first time domain resource is used for the transmission of the uplink channel on the time domain resource that does not contain the uplink reference signal. In addition, if the first time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power can be determined according to this method on each time domain resource unit of the first time domain resource. If the second time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power allocated to the uplink channel on each time domain resource unit of the first time domain resource is used on each time domain resource unit of the second time domain resource.

[0157] In method 3 of the embodiment of the present application, the power of the RE transmitting the uplink channel on different time domain resources is the same, thereby ensuring that the transmission power of the uplink channel on different time domain resources is the same, which is convenient for the receiving end to detect, but at the same time reduces the transmission power on each time domain resource.

[0158] It can be understood that in the embodiment of the present application, when the first power ratio is defined as Definition 2, on the first time domain resource, the terminal device allocates the first transmit power to the uplink reference signal and the uplink channel according to the first power ratio, thereby obtaining the transmit power of the uplink reference signal and the uplink channel on the first time domain resource. On the second time domain resource, the terminal device can determine the transmit power of the uplink channel in one of the following two ways:

[0159] Mode A: Using the first transmit power as the power of the uplink channel on the second time domain resource;

[0160] Mode B: The transmit power of REs allocated to uplink channels on the first time domain resources is used as the transmit power of REs of uplink reference signals on the second time domain resources.

[0161] In some embodiments, if the first power ratio is defined as Definition 3, the method for determining the transmit power of the uplink reference signal and the transmit power of the uplink channel includes Method 4:

[0162] Allocating, on the first time domain resource, a first transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio;

[0163] The first transmit power is allocated to the uplink channel on a second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0164] Specifically, on the first time domain resource, the terminal device allocates the first transmission power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio, thereby obtaining the transmission power of the uplink reference signal and the uplink channel.

[0165] In method 4, on the time domain resource that does not include the uplink reference signal in the second physical resource, i.e., the second time domain resource, the terminal device allocates the first transmit power to the uplink channel. That is, on the second time domain resource, the terminal device directly uses the first transmit power for the transmission of the uplink channel.

[0166] It should be noted that if the first time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power can be determined according to this method on each time domain resource unit of the first time domain resource.

[0167] In method 4 of the embodiment of the present application, the transmission power of the RE on the second time domain resource is not affected, but the transmission power of the uplink channel on different time domain resources is different (the transmission power of the uplink channel on the first time domain resource is lower than the transmission power of the uplink channel on the second time domain resource), and the requirements for the detection at the receiving end are higher.

[0168] In some embodiments, if the first power ratio is defined as Definition 3 or Definition 4, the method for determining the transmit power of the uplink reference signal and the transmit power of the uplink channel includes Method 5:

[0169] Allocating, on the first time domain resource, a first transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio;

[0170] The transmission power of the RE of the uplink channel on the first time domain resource is used for the RE of the uplink channel on the second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0171] On the first time domain resource, the terminal device allocates the first transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio, thereby obtaining the transmit power of the uplink reference signal and the uplink channel.

[0172] In method 5, the transmission power of REs allocated to uplink channels on the first time domain resource is used for REs of uplink channels on the second time domain resource. That is, the power of REs transmitting uplink channels on different time domain resources is the same.

[0173] It should be noted that this method can also be described as: the transmission power allocated to the uplink channel on the first time domain resource is used for the transmission of the uplink channel on the second time domain resource, that is, the transmission power allocated to the uplink channel on the first time domain resource is used for the transmission of the uplink channel on the time domain resource that does not contain the uplink reference signal.

[0174] In addition, if the first time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power can be determined according to this method for each time domain resource unit of the first time domain resource. If the second time domain resource includes multiple time domain resource units (such as multiple OFDM symbols), the transmit power allocated to the uplink channel for each time domain resource unit of the first time domain resource is used for each time domain resource unit of the second time domain resource.

[0175] In method 5 of the embodiment of the present application, the power of transmitting uplink channels on different time domain resources is the same, thereby ensuring that the transmission power of uplink channels on different time domain resources is the same, which is convenient for detection by the receiving end, but at the same time reduces the transmission power on each time domain resource in proportion.

[0176] It can be understood that in the embodiment of the present application, on the first time domain resource, the terminal device allocates the first transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio, thereby obtaining the transmit power of the uplink reference signal and the uplink channel on the time domain resource. On the second time domain resource, the terminal device can determine the transmit power of the uplink channel in one of the following two ways:

[0177] Mode A: Using the first transmit power as the power of the uplink channel on the second time domain resource;

[0178] Mode B: The transmit power of REs allocated to uplink channels on the first time domain resources is used as the transmit power of REs of uplink reference signals on the second time domain resources.

[0179] In some embodiments, allocating the first transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio on the first time domain resource includes:

[0180] On the first time domain resource, the first transmit power is allocated to the uplink reference signal and the uplink channel according to a second power ratio. Furthermore, the allocated power of the uplink reference signal and the uplink channel can be evenly distributed to each uplink reference signal RE and each uplink channel RE, thereby ensuring that the power ratio of each uplink reference signal RE and each uplink channel RE meets the first power ratio. The second power ratio is the first power ratio multiplied by a first coefficient, where the first coefficient is the ratio between the number of REs occupied by the uplink reference signal and the number of REs occupied by the uplink channel on the first time domain resource.

[0181] At this point, the above method 4 can be described as:

[0182] On the first time domain resource, the first transmit power is allocated to the uplink reference signal and the uplink channel according to a second power ratio; wherein the second power ratio is the first power ratio multiplied by a first coefficient, and the first coefficient is the ratio between the number of REs occupied by the uplink reference signal and the number of REs occupied by the uplink channel on the first time domain resource.

[0183] The first transmit power is allocated to the uplink channel on a second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0184] The above method 5 can be described as:

[0185] On the first time domain resource, the first transmit power is allocated to the uplink reference signal and the uplink channel according to a second power ratio; wherein the second power ratio is the first power ratio multiplied by a first coefficient, and the first coefficient is the ratio between the number of REs occupied by the uplink reference signal and the number of REs occupied by the uplink channel on the first time domain resource.

[0186] The transmission power of the uplink channel on the first time domain resource is used for the uplink channel on the second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0187] In method 4 and method 5, for the first time domain resource, the terminal device allocates the first transmit power to the uplink reference signal and the uplink channel according to the second power ratio; wherein the second power ratio is the first power ratio multiplied by a first coefficient, the first coefficient is related to the first quantity and the second quantity, the first quantity is the number of REs occupied by the uplink reference signal in the first time domain resource, and the second quantity is the number of REs occupied by the uplink channel in the first time domain resource.

[0188] Optionally, the first coefficient is a ratio of the first quantity to the second quantity.

[0189] In one example, assuming that the first power ratio is 0.4:0.6, which represents the ratio between the EPRE of the uplink reference signal and the EPRE of the uplink channel on the first time domain resource, and the ratio between the number of REs occupied by the uplink reference signal on the first time domain resource, i.e., the first number, and the number of REs occupied by the uplink channel, i.e., the second number (the first coefficient), is 1:2, then the second power ratio is (0.4*1):(0.6*2)=1:3. At this time, the terminal device distributes the calculated uplink transmit power to the uplink reference signal and the uplink channel in a ratio of 1:3, respectively, to obtain the transmit power of the uplink reference signal and the uplink channel in the first time domain resource. At this time, the transmit power of the uplink reference signal is evenly distributed to the RE of each uplink reference signal in the first time domain resource, and the transmit power of the uplink channel is evenly distributed to the RE of each uplink channel in the first time domain resource, so as to ensure that the power ratio on each RE of the first physical resource is 0.4:0.6.

[0190] In some embodiments, the terminal device determines the transmit power of the uplink reference signal and the transmit power of the uplink channel, including method 6:

[0191] The terminal device determines that the transmit power of the uplink channel is a first transmit power;

[0192] The terminal device determines the transmit power of the uplink reference signal based on the first transmit power and a first power ratio, wherein the first power ratio is a ratio between the transmit power of the uplink reference signal and the transmit power of the uplink channel.

[0193] In method 6, the terminal device uses the first transmit power for an uplink channel on the second physical resource, and determines the transmit power of the uplink reference signal based on the first transmit power and a first power ratio. The first power ratio may be defined as any one of Definitions 1 to 4.

[0194] It is understandable that in method 6, the uplink reference signal does not need to be divided from the uplink channel power, but is superimposed with a certain power ratio using independent transmission power, so that the transmission power of the uplink channel is not affected by the superimposed uplink reference signal.

[0195] In the embodiment of the present application, the transmit power on the first time domain resource is the sum of the first transmit power and the transmit power of the uplink reference signal.

[0196] In one example, the transmission power of the uplink channel on each OFDM symbol is P1, and the transmission power of the uplink reference signal on each OFDM symbol is P2. Then, on the symbol containing the uplink reference signal, that is, the first time domain resource, the transmission power of the terminal device is P1+P2, and on the symbol not containing the uplink reference signal, the transmission power of the terminal device is P1.

[0197] It should be noted that, in any one of methods 1 to 5, the uplink reference signal and the uplink channel share the first transmission power.

[0198] In an embodiment of the present application, for method 6, if the second transmit power exceeds the maximum transmit power supported by the terminal device, the transmit power of the uplink reference signal and / or the transmit power of the uplink channel is reduced until the second transmit power does not exceed the maximum transmit power supported by the terminal device. The second transmit power is the sum of the transmit powers of the uplink reference signal and the uplink channel on the first time domain resource.

[0199] The manner of reducing the transmit power of the uplink reference signal and / or the transmit power of the uplink channel includes one of reduction manner 1 and reduction manner 2:

[0200] Reduction mode 1: reducing only the transmit power of the uplink reference signal and / or the transmit power of the uplink channel on the first physical resource;

[0201] Reduction method 2: reducing the transmission power of the uplink reference signal and / or the transmission power of the uplink channel on the first time domain resource.

[0202] For reduction method 1, if the second transmit power exceeds the maximum transmit power supported by the terminal device, the terminal device reduces the transmit power of the uplink reference signal and / or the transmit power of the uplink channel on the first physical resource until the second transmit power does not exceed the maximum transmit power supported by the terminal device; the second transmit power is the sum of the transmit powers of the uplink reference signal and the uplink channel on the first time domain resource, and the first time domain resource is the time domain resource where the uplink reference signal is located.

[0203] In reduction method 1, only the transmission power of the uplink reference signal can be reduced, or only the transmission power of the uplink channel on the first physical resource can be reduced to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0204] In reduction method 1, the transmission power of the uplink reference signal and the transmission power of the uplink channel on the first physical resource can be reduced simultaneously to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device, and the power ratio between the two is kept unchanged.

[0205] In some embodiments, reducing the transmit power of the uplink reference signal and the transmit power of the uplink channel on the first physical resource includes:

[0206] reducing the transmit power of the uplink reference signal and the uplink channel on the first physical resource according to a second coefficient;

[0207] The second coefficient is the ratio of the first power to the second power, the first power is the difference between the maximum transmit power supported by the terminal device and the total transmit power of the uplink channel on the first RE in the first time domain resource, the first RE is the RE on the first time domain resource that is not used to transmit the uplink reference signal, and the second power is the sum of the total transmit power of the uplink reference signal on the first time domain resource and the total transmit power of the uplink channel on the RE on the first time domain resource used to transmit the uplink reference signal.

[0208] In the embodiment of the present application, the transmit power of the uplink reference signal and the uplink channel on the first physical resource is proportionally reduced according to the second coefficient, that is, the transmit power of the uplink reference signal is multiplied by the second coefficient to obtain the actual transmit power of the uplink reference signal, and the transmit power of the uplink channel on the first physical resource is multiplied by the second coefficient to obtain the actual transmit power of the uplink channel on the first physical resource. The value of the second coefficient is less than 1.

[0209] Optionally, the value of the second coefficient can be expressed as: (P max -P1) / (P2+P3), where Pmax -P1 is the first power, P max is the maximum transmit power supported by the terminal device, P1 is the total transmit power of the uplink channels on the REs that are not used for transmitting uplink reference signals on the first time domain resources, P2+P3 is the second power, P2 is the total transmit power of the uplink reference signals on the first time domain resources, and P3 is the total transmit power of the uplink channels on the REs that are used to transmit uplink reference signals on the first time domain resources.

[0210] In the embodiment of the present application, since P1+P2+P3 is greater than P max , therefore, the second coefficient is less than 1. After the transmit power on the first physical resource is reduced based on the second coefficient, the sum of the transmit power of the uplink reference signal and the uplink channel will be equal to the maximum transmit power supported by the terminal device, thereby ensuring the transmit power as much as possible while keeping the power ratio between the uplink reference signal and the uplink channel unchanged.

[0211] For reduction mode 1, only signal transmission on the first physical resource will be affected, and signal transmission on other physical resources on the second physical resource except the first physical resource will not be affected, thereby reducing the impact on uplink channel transmission.

[0212] For reduction method 2, if the second transmit power exceeds the maximum transmit power supported by the terminal device, the terminal device reduces the transmit power of the uplink reference signal and / or the transmit power of the uplink channel on the first time domain resource until the second transmit power does not exceed the maximum transmit power supported by the terminal device; the second transmit power is the sum of the transmit powers of the uplink reference signal and the uplink channel on the first time domain resource, and the first time domain resource is the time domain resource where the uplink reference signal is located.

[0213] In reduction method 2, only the transmission power of the uplink reference signal can be reduced, or only the transmission power of the uplink channel on the first time domain resource can be reduced to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0214] In reduction method 2, the transmission power of the uplink reference signal and the transmission power of the uplink channel on the first time domain resource can be reduced simultaneously to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device, while keeping the power ratio between the two unchanged.

[0215] In some embodiments, reducing the transmit power of the uplink reference signal and the transmit power of the uplink channel on the first time domain resource includes:

[0216] The transmission power of the uplink reference signal and the uplink channel on the first time domain resource is reduced according to a third coefficient, wherein the third coefficient is the ratio of the maximum transmission power supported by the terminal device to the sum of the transmission powers.

[0217] The terminal device proportionally reduces the transmit power of the uplink reference signal and the uplink channel on the first time domain resource according to the third coefficient, that is, multiplying the transmit power of the uplink reference signal and the uplink channel by the third coefficient to obtain the actual transmit power. The value of the third coefficient is less than 1.

[0218] Optionally, the third coefficient is the maximum transmit power P supported by the terminal device max and the ratio between the second transmission power.

[0219] For reduction method 2, in some embodiments, the power reduction operation is performed only on the time domain resource where the uplink reference signal is located, and the uplink channels on other time domain resources are not affected and are still transmitted according to the calculated transmit power.

[0220] Regarding reduction mode 2, in some embodiments, the method further includes:

[0221] The terminal device uses the reduced transmit power of the uplink channel on the first time domain resource for the uplink channel on the second time domain resource, where the second time domain resource is a time domain resource in the second physical resource that is not used to transmit the uplink reference signal. If the second time domain resource includes multiple time domain resource units, each time domain resource unit uses the transmit power on the first time domain resource.

[0222] The terminal device uses the reduced transmit power of the uplink channel on the first time domain resource as the transmit power of the uplink channel on the second time domain resource. In other words, the power reduction operation is performed on all time domain resources occupied by the uplink channel, ensuring that the transmit power of the uplink channels on different time domain resources is consistent, reducing the detection complexity at the receiving end.

[0223] In some embodiments, the first transmit power is an expected transmit power of the uplink channel determined according to a power control parameter configured by a network device.

[0224] Optionally, the terminal device determines the expected transmission power of the uplink channel, i.e., the first transmission power, based on the agreed transmission power calculation method and the power control parameters configured by the network device.

[0225] In one example, the terminal device may use formula (1) to calculate the first transmission power.

[0226] In the embodiment of the present application, the power control parameters are a set of power control parameters specially configured by the network device for the superimposed transmission of the uplink reference signal and the uplink channel, which are different from the power control parameters used in the traditional non-superimposed case.

[0227] In some embodiments, the first power ratio is pre-agreed upon by the terminal device and the network device, or is notified to the terminal device by the network device through downlink signaling.

[0228] In the case where the first power ratio is pre-agreed upon by the terminal device and the network device, the network device may not need to indicate the first power ratio to the terminal device, thereby reducing the signaling overhead between the network device and the terminal device.

[0229] In some embodiments, based on the method shown in FIG4 , the wireless communication method provided in the embodiment of the present application further includes:

[0230] The network device indicates a first power ratio to the terminal device, where the first power ratio is used by the terminal device to determine the transmission power of the uplink reference signal and the uplink channel.

[0231] The network device may send power information to the terminal device, and the terminal device determines the first power ratio based on the power information sent by the network device.

[0232] Optionally, the power information indicates a power ratio value among multiple power ratio values, and the power ratio value indicated by the power information is a first power ratio value.

[0233] The multiple power ratios may constitute a power ratio set, and different power ratio sets in the power ratio set may have different indexes. The power information may be the index of the first power ratio.

[0234] In an example, the power ratio value set may be {0.1:0.9, 0.2:0.8, 0.3:0.7, 0.4:0.6, 0.5:0.5}, and the power information may indicate that 0.3:0.7 in the power ratio value set is the first power ratio value.

[0235] Optionally, the network device may indicate the first power ratio from a pre-agreed power ratio set through high-layer signaling or physical-layer signaling.

[0236] Optionally, the power information indicates a power weight, and the first power ratio is represented by the power weight.

[0237] In one example, when the transmission power ratio between the uplink reference signal and the uplink channel is 0.2:0.8, the power weight may be 0.2 or 0.8. It is understandable that the power weight and the power ratio are equivalent.

[0238] In some embodiments, based on FIG3 , the wireless communication method provided in the embodiment of the present application, as shown in FIG11 , further includes:

[0239] S1101. The terminal device sends a first power headroom report PHR, where the first PHR is the power headroom on a first time domain resource, and the first time domain resource is the time domain resource where the uplink reference signal is located.

[0240] In some embodiments, based on FIG4 , the wireless communication method provided in the embodiment of the present application, as shown in FIG12 , further includes:

[0241] S1201. The network device receives a first power headroom report PHR, where the first PHR is a power headroom on a first time domain resource, and the first time domain resource is a time domain resource where the uplink reference signal is located.

[0242] In some embodiments, the first PHR is the difference between the maximum transmit power supported by the terminal device and a third transmit power, the third transmit power is the sum of the transmit power of the uplink channel on the first time domain resource and the transmit power of the uplink reference signal, or the third transmit power is the transmit power of the uplink channel on the first time domain resource.

[0243] Optionally, if the method used by the terminal device to determine the power of the uplink reference signal and the power of the uplink channel is any one of Method 1 to Method 6, the first PHR is the maximum transmit power supported by the terminal device and the transmit power of the uplink channel on the first time domain resource. In other words, the first PHR takes into account the transmit power of the uplink channel on the first time domain resource.

[0244] Optionally, if the method for the terminal device to determine the power of the uplink reference signal and the power of the uplink channel is any one of method 1 to method 6, the first PHR includes the power margin on the first time domain resource, and the power margin on the first time domain resource is the maximum transmit power P supported by the terminal device. max The difference between the first and third transmit powers, wherein the third transmit power is the sum of the transmit powers of the uplink channel and the uplink reference signal on the first time domain resource, that is, the first PHR takes into account the transmit power of all uplink signals on the first time domain resource.

[0245] In some embodiments, based on FIG11 , the wireless communication method provided in the embodiment of the present application further includes:

[0246] Based on the first PHR, the terminal device sends a second PHR, where the second PHR is the power margin on a second time domain resource, and the second time domain resource is a time domain resource in the second physical resource that is not used to transmit the uplink reference signal.

[0247] In some embodiments, based on FIG12 , the wireless communication method provided in the embodiment of the present application further includes:

[0248] The network device receives a second PHR, where the second PHR is a power headroom on a second time domain resource, and the second time domain resource is a time domain resource in the second physical resource that is not used for transmitting the uplink reference signal.

[0249] The second PHR includes a power headroom on a time domain resource where the uplink reference signal is not transmitted.

[0250] In some embodiments, the second PHR is the difference between the maximum transmit power supported by the terminal device and a fourth transmit power, and the fourth transmit power is the transmit power of the uplink channel on the second time domain resource.

[0251] Among them, if the terminal device has the same transmit power or the same power margin on the first time domain resource and the second time domain resource, the terminal device can only report the first PHR and does not need to report the second PHR. If the terminal device has different transmit power or different power margin on the first time domain resource and the second time domain resource, the terminal device can report the first PHR and the second PHR at the same time, so that the network device determines the power margin on different time domain resources, thereby performing reasonable scheduling. Among them, the first PHR and the second PHR can be reported together in the same uplink resource (PUSCH).

[0252] It should be noted that if the transmission power of each time domain resource unit on the second physical resource is the same, the terminal device can send a third PHR to the network device. The third PHR is the PHR of the second physical resource, that is, the difference between the maximum transmission power supported by the terminal device and the transmission power on each symbol in the second physical resource.

[0253] Below, taking the uplink reference signal as DMRS and the uplink channel as PIUSCH for transmitting data as an example, the wireless communication method provided by the embodiment of the present application is described through multiple embodiments.

[0254] Example 1

[0255] S1301. The network device configures a first physical resource for transmitting an uplink reference signal of a terminal device and a second physical resource for transmitting an uplink channel of the terminal device, wherein the first physical resource is part of the second physical resource.

[0256] a) The uplink reference signal may be DMRS, SRS, PTRS, etc.

[0257] b) The uplink channel may be an uplink channel for carrying uplink data (such as PUSCH), or an uplink channel for carrying uplink control information (such as PUCCH).

[0258] c) The first physical resource is used to transmit both the uplink reference signal and the uplink channel; the other resources in the second physical resource are only used to transmit the uplink channel. Among them, the physical resource is also called time-frequency resource, which is a two-dimensional resource area of ​​time and frequency composed of the minimum time-frequency resource unit RE. The second physical resource can include multiple time domain resources (such as OFDM symbols or time slots) in the time domain, and can include multiple frequency domain resources (such as PRBs or subcarriers) in the frequency domain. For example, it can be several symbols in the time domain and several PRBs in the frequency domain. The first physical resource can occupy some subcarriers on some time domain resources (such as an OFDM symbol) in the second physical resource.

[0259] d) Taking the uplink reference signal as DMRS and the uplink channel as PUSCH as an example, the allocation of the first physical resource and the second physical resource in one PRB can be as shown in any one of Figures 14 to 19 (each grid in the figure represents an RE). The DMRS+data part in the figure is the second physical resource, and the first physical resource includes the DMRS+data part and the Data part. Among them, in Figure 14, PUSCH occupies the entire PRB (second physical resource), and DMRS occupies one of the subcarriers (first physical resource); in Figure 15, PUSCH occupies 12 OFDM symbols (second physical resource), and DMRS occupies one subcarrier on half of the OFDM symbols (first physical resource); in Figure 16, PUSCH occupies 12 OFDM symbols (second physical resource), and DMRS occupies the first OFDM symbol (first physical resource); in Figure 17, PUSCH occupies 12 OFDM symbols (second physical resource), and DMRS occupies the first OFDM symbol (first physical resource). RS occupies half of the subcarriers on the first OFDM symbol (first physical resource); in Figure 18, PUSCH occupies 12 OFDM symbols (second physical resource), and DMRS occupies 3 subcarriers (first physical resource) on two consecutive OFDM symbols (the first OFDM symbol and the second OFDM symbol); in Figure 19, PUSCH occupies 12 OFDM symbols (second physical resource), and DMRS occupies 3 subcarriers (first physical resource) on two discontinuous OFDM symbols (the first OFDM symbol and the seventh OFDM symbol).

[0260] It should be noted that the second physical resource may include multiple PRBs, wherein each PRB may adopt resource allocation similar to any one of the diagrams in FIG. 14 to FIG. 19 .

[0261] It should be noted that 603 in the embodiment of the present application is used to identify the control channel.

[0262] e) The network device can schedule other terminal devices on the second physical resource to be multiplexed with the terminal device. In one embodiment, the network device schedules the uplink channel of the second terminal device on the second physical resource, and schedules the uplink reference signal of the second terminal device on other physical resources in the second physical resource except the first physical resource. Taking Figures 14 and 17 as examples, the transmission resources of the terminal device (UE1) and the second terminal device (UE2) are shown in Figures 20 and 21. It should be noted that the resources used to transmit DMRS in Figure 20 are also used to transmit data for UE1 and UE2. Among them, in Figures 20 and 21, 701 is used to identify the RE for transmitting data of UE1 and UE2, 702 is used to identify the RE for transmitting data of UE1 and UE2 and DMRS of UE1, 703 is used to identify the RE for transmitting data of UE1 and UE2 and DMRS of UE2, and 704 is used to identify the control channel.

[0263] In another embodiment, more terminal devices can be multiplexed on the second physical resource, where the DMRSs of different terminal devices occupy different REs on the second physical resource. For example, the second physical resource is divided into several DMRS resources (ports), each terminal device can occupy one of the DMRS resources for DMRS transmission, and the first physical resource can be one of the DMRS resources. For example, the DMRS resources can be divided as follows (different DMRS resources do not overlap):

[0264] 1) Each DMRS resource occupies a different subcarrier (as shown in Figure 14), and each PRB can support up to 12 DMRS resources (12 subcarriers);

[0265] 2) Each DMRS resource occupies a different OFDM symbol (as shown in Figure 16), and each PRB can support up to 14 DMRS resources (14 OFDM symbols);

[0266] 3) Each DMRS resource occupies 6 subcarriers on an OFDM symbol (for example, odd subcarriers or even subcarriers, as shown in Figure 17, so that each OFDM symbol can have 2 resources), and each PRB can support up to 24 or 28 DMRS resources;

[0267] 4) Each DMRS resource occupies 1 subcarrier on 6 or 7 OFDM symbols (for example, odd or even OFDM symbols, as shown in Figure 15, so that one subcarrier can support 2 resources on all symbols), and each PRB can support up to 24 DMRS resources.

[0268] 5) Each DMRS resource occupies several subcarriers on two or three OFDM symbols. These two or three OFDM symbols can be continuous (as shown in Figure 18) or discontinuous (as shown in Figure 19).

[0269] The network device may indicate the first physical resource and the second physical resource through physical layer signaling or high layer signaling. For example, the network device may indicate the DMRS resource used by the terminal device as the first physical resource from the aforementioned several DMRS resources (ports) through DCI signaling.

[0270] S1302. The terminal device determines a first physical resource for transmitting an uplink reference signal and a second physical resource for transmitting an uplink channel.

[0271] a) The terminal device may determine the first physical resource and the second physical resource based on the configuration of the network device, as specifically shown in S1301.

[0272] S1303. The terminal device determines the transmission power of the uplink reference signal and the uplink channel.

[0273] a) The terminal device may obtain a first power ratio according to the power information indicated by the network device, and then determine the transmit power according to the first power ratio, wherein the first power ratio is the transmit power ratio between the uplink reference signal and the uplink channel.

[0274] In one embodiment, the power information indicates the first power ratio. Specifically, the network device may indicate the first power ratio from a pre-agreed power ratio set via high-layer signaling or physical-layer signaling. For example, the power ratio set may be {0.1:0.9, 0.2:0.8, 0.3:0.7, 0.4:0.6, 0.5:0.5}.

[0275] In another embodiment, the power information may indicate a power weight, and the first power ratio may be represented by a power weight. Specifically, it may be represented by a power weight of the uplink reference signal or the uplink channel. For example, when the transmit power ratio between the uplink reference signal and the uplink channel is 0.2:0.8, the power weight may be 0.2 or 0.8. The power weight and the power ratio are equivalent.

[0276] It should be noted that if the uplink channel carries multiple transmission layers, the first power ratio is the transmission power ratio between the uplink reference signal corresponding to each layer and the data of each layer (ie, the ratio is per layer).

[0277] In another embodiment, the first power ratio may also be the transmission power ratio between the uplink channel and the uplink reference signal. The description method is different, but the actual effect is the same.

[0278] b) The first power ratio is a transmission power ratio between the uplink reference signal and the uplink channel on the first physical resource.

[0279] c) The terminal device determines the transmission power of the uplink reference signal and the uplink channel based on the first power ratio.

[0280] In one embodiment, the terminal device distributes the uplink transmit power, i.e., the first transmit power, evenly to the second physical resource; and then distributes the uplink transmit power allocated to the first physical resource to the uplink reference signal and the uplink channel according to the first power ratio. That is to say, the transmit power on different REs of the second physical resource is the same, wherein the power on the first physical resource is to be distributed to the uplink reference signal and the uplink channel, and the transmit power on other REs is only used for uplink channel transmission. For example, assuming that the transmit power allocated to each RE is 1, and the first power ratio is 0.4:0.6, then on the first physical resource, the transmit power of the uplink reference signal and the uplink channel are 0.4 and 0.6 respectively; on other resources of the second physical resource, the transmit power of the uplink channel is 1.

[0281] It should be noted that if the uplink channel carries multiple transmission layers, the transmission power of the uplink channel needs to be evenly distributed to each transmission layer.

[0282] Based on the method of this embodiment, the superimposed transmission of the uplink reference signal and the uplink channel will only affect the transmission power of the uplink channel on the first physical resource, and the uplink channels on other physical resources will not be affected, thereby minimizing the impact of the superimposed transmission on the transmission performance of the uplink channel. The uplink transmission power is the expected transmission power of the uplink channel determined by the terminal device according to the agreed transmission power calculation method and the power control parameters configured by the network device. For example, the method described in the aforementioned "Uplink PUSCH Power Control" can be adopted. The power control parameters can be a set of power control parameters specially configured by the network device for the superimposed transmission of the uplink reference signal and the uplink channel, which is different from the power control parameters used in the traditional non-superimposed case.

[0283] d) In one embodiment, the terminal device reports a PHR to the network device, where the PHR is the PH value in the second physical resource, that is, the difference between the maximum transmit power supported by the terminal device and the transmit power on each OFDM symbol in the second physical resource.

[0284] S1304. The terminal device sends the uplink reference signal and the uplink channel on the first physical resource and the second physical resource respectively based on the transmission power.

[0285] S1305. The network device receives the uplink reference signal and the uplink channel on the first physical resource and the second physical resource.

[0286] In one embodiment, the network device uses the signal received on the second physical resource as the input of the AI ​​model, thereby outputting the data bits carried by the uplink channel of the terminal device. Furthermore, if the second physical resource also carries the uplink channel of the second terminal device, the AI ​​model can simultaneously output the data bits of the terminal device and the data bits of the second terminal device. The input of the AI ​​model may also include the sequence of the uplink reference signal and the sequence of the uplink reference signal of the second terminal device.

[0287] Example 2

[0288] S1301. The network device configures a first physical resource for transmitting an uplink reference signal of a terminal device and a second physical resource for transmitting an uplink channel of the terminal device, wherein the first physical resource is part of the second physical resource.

[0289] The first physical resource is used to transmit both the uplink reference signal and the uplink channel; the other resources in the second physical resource are only used to transmit the uplink channel. For details, please refer to the description in the first embodiment.

[0290] S1302. The terminal device determines a first physical resource for transmitting an uplink reference signal and a second physical resource for transmitting an uplink channel.

[0291] The terminal device can determine the first physical resource and the second physical resource based on the configuration of the network device, as shown in Example 1.

[0292] S1303. The terminal device determines the transmission power of the uplink reference signal and the uplink channel.

[0293] a) In one embodiment, the terminal device may obtain a first power ratio based on power information indicated by the network device, and then determine the transmit power based on the ratio. The first power ratio is the transmit power ratio between the uplink reference signal and the uplink channel. For a specific indication method, refer to the description in Example 1.

[0294] In another embodiment, the first power ratio may be pre-agreed upon between the terminal device and the network device. For example, the terminal device and the network device may pre-agreed upon that the transmit power of the uplink channel and the uplink reference signal on the first physical resource are the same (i.e., the first power ratio is 1).

[0295] b) In one embodiment, the first power ratio is the ratio of the total transmit power of the uplink reference signal to the total transmit power of the uplink channel on the time domain resource where the uplink reference signal is located. The terminal device allocates the uplink transmit power to the uplink reference signal and the uplink channel according to the first power ratio on the time domain resource where the uplink reference signal is located, thereby obtaining the transmit power of the uplink reference signal and the uplink channel on the time domain resource.

[0296] The time domain resource in the embodiments of the present application is a basic time domain unit for transmitting uplink signals, such as an OFDM symbol. For example, if an OFDM transmission scheme is adopted, the time domain resource where the uplink reference signal is located may be the OFDM symbol where the uplink reference signal is located, such as the third OFDM symbol in FIG16 , or the 3rd, 5th, 7th, 9th, 11th, and 13th OFDM symbols in FIG15 . The same applies hereinafter.

[0297] Furthermore, the terminal device may distribute the total transmit power of the uplink reference signal to each RE that transmits the uplink reference signal in the time domain resource, and distribute the total transmit power of the uplink channel to each RE that transmits the uplink channel in the time domain resource. For example, assuming that the uplink transmit power is 23dBm and the first power ratio is 1, the transmit power of the uplink reference signal and the uplink channel in the time domain resource are 20dBm respectively, and the terminal device needs to evenly distribute these powers to each RE that transmits them.

[0298] Furthermore, on the time domain resources that do not include the uplink reference signal in the second physical resource (for example, the 4th to 14th OFDM symbols in Figure 16, or the 4th, 6th, 8th, 10th, 12th, and 14th OFDM symbols in Figure 15), the terminal device can determine the transmit power of the uplink channel in one of the following two ways:

[0299] Method a: Allocate the uplink transmit power to the uplink channel. That is, on these time-domain resources, the terminal device can directly use the uplink transmit power for uplink channel transmission. This method does not affect the transmit power on these time-domain resources, but the transmit power of uplink channels on different time-domain resources varies (the power on symbols with uplink reference signals is lower), placing higher demands on the receiving end for detection.

[0300] Method b: The transmission power allocated to the uplink channel on the time domain resource where the uplink reference signal is located is used for the transmission of the uplink channel on the time domain resource that does not contain the uplink reference signal. In other words, the power for transmitting the uplink channel on different time domain resources is the same. For example, the transmission power of the uplink channel on the 3rd OFDM symbol in Figure 16 can be used for the uplink channel on the 4th to 14th OFDM symbols at the same time, thereby ensuring that the PUSCH transmission power on different OFDM symbols is the same. This method can ensure that the transmission power of the uplink channels on different time domain resources is the same, which is convenient for the receiving end to detect, but at the same time reduces the transmission power on each time domain resource.

[0301] The uplink transmit power is the expected transmit power of the uplink channel determined by the terminal device according to the agreed transmit power calculation method and the power control parameters configured by the network device. For example, the method described in the aforementioned "Uplink PUSCH Power Control" can be used.

[0302] c) In another embodiment, the first power ratio is the ratio of the transmit power of the uplink reference signal on each resource unit RE to the transmit power of the uplink channel on each RE on the time domain resource where the uplink reference signal is located. The terminal device allocates the uplink transmit power to the RE of the uplink reference signal and the RE of the uplink channel according to the first power ratio on the time domain resource, thereby obtaining the transmit power on each RE of the uplink reference signal and the uplink channel.

[0303] The transmit power of the uplink reference signal on each RE is also called the EPRE of the uplink reference signal, and the transmit power of the uplink channel on each RE is also called the EPRE of the uplink channel. At this time, the first power ratio can be the ratio between the EPRE of the uplink reference signal (such as DMRS) and the EPRE of the uplink channel (such as PUSCH) in the time domain resource, or the ratio between the EPRE of the uplink reference signal (such as DMRS) and the EPRE of the uplink channel (such as PUSCH) in the first physical resource. Furthermore, the first power ratio can also be expressed by the ratio between the EPRE of the uplink channel (such as PUSCH) and the EPRE of the uplink reference signal (such as DMRS), which is equivalent to the above-mentioned method.

[0304] On the time domain resource where the uplink reference signal is located, the terminal device allocates the uplink transmit power to the uplink reference signal and the uplink channel according to a second power ratio, and evenly distributes the allocated power to each uplink reference signal RE and each uplink channel RE; wherein the second power ratio is the first power ratio multiplied by a first coefficient, and the first coefficient is the ratio between the number of REs occupied by the uplink reference signal and the number of REs occupied by the uplink channel on the time domain resource where the uplink reference signal is located. For example, taking Figure 17 as an example, assuming that the first power ratio is 0.4:0.6, it represents the ratio between the EPRE of the uplink reference signal and the EPRE of the uplink channel on the time domain resource where the uplink reference signal is located. Since the ratio between the number of REs occupied by the uplink reference signal and the number of REs occupied by the uplink channel on the time domain resource at this time (the first coefficient) is 1:2, the second power ratio is (0.4*1):(0.6*2)=1:3. At this time, the terminal device will distribute the calculated uplink transmit power to the uplink reference signal and the uplink channel in a ratio of 1:3, obtain the transmit power of the uplink reference signal and the uplink channel in the time domain resource, and then distribute these powers evenly to each RE, thereby ensuring that the power ratio on each RE of the first physical resource is 0.4:0.6.

[0305] On the time domain resources that do not include the uplink reference signal in the second physical resource (for example, the 4th to 14th OFDM symbols in FIG. 16 , or the 4th, 6th, 8th, 10th, 12th, and 14th OFDM symbols in FIG. 15 ), the terminal device may determine the transmit power of the uplink channel in one of the following two ways:

[0306] Method a: Allocate the uplink transmit power to the uplink channel. That is, on these time-domain resources, the terminal device can directly use the uplink transmit power for uplink channel transmission. This method does not affect the transmit power on these time-domain resources, but the transmit power of uplink channels on different time-domain resources varies (the power on symbols with uplink reference signals is lower), placing higher demands on the receiving end for detection.

[0307] Mode b: The transmit power on the RE of the uplink channel on the time domain resource where the uplink reference signal is located is used as the transmit power of the uplink channel on other REs in the second physical resource. That is, the transmit power allocated to the uplink channel on the time domain resource where the uplink reference signal is located is used for the transmission of the uplink channel on the time domain resource that does not contain the uplink reference signal. In other words, the power of transmitting the uplink channel on different time domain resources is the same. For example, the transmit power of the uplink channel on the 3rd OFDM symbol in Figure 17 can be used for the uplink channel on the 4th to 14th OFDM symbols at the same time, thereby ensuring that the PUSCH transmit power on different OFDM symbols is the same.

[0308] d) Based on this method, the superimposed transmission of the uplink reference signal and the uplink channel only affects the transmit power of the uplink channel on the time domain resource where the uplink reference signal resides, while the uplink channels on other time domain resources remain unaffected. This minimizes the impact of superimposed transmission on the transmission performance of the uplink channel. Furthermore, because the power of the uplink reference signal is distributed across all subcarriers in the time domain resource, the power reduction per subcarrier is relatively small.

[0309] e) The terminal device reports the first PHR and the second PHR to the network device.

[0310] The first PHR includes the power headroom of the uplink channel on the time domain resource where the uplink reference signal is located, and the second PHR includes the power headroom of the uplink channel on the time domain resource where the uplink reference signal is not transmitted.

[0311] The power margin is the difference between the maximum transmission power supported by the terminal device and the transmission power of the uplink channel on the corresponding time domain resource.

[0312] S1304. The terminal device sends the uplink reference signal and the uplink channel on the first physical resource and the second physical resource respectively based on the transmission power.

[0313] S1305. The network device receives the uplink reference signal and the uplink channel on the first physical resource and the second physical resource.

[0314] Example 3

[0315] S1301. The network device configures a first physical resource for transmitting an uplink reference signal of a terminal device and a second physical resource for transmitting an uplink channel of the terminal device, wherein the first physical resource is part of the second physical resource.

[0316] The first physical resource is used to transmit both the uplink reference signal and the uplink channel; the other resources in the second physical resource are only used to transmit the uplink channel. For details, please refer to the description in the first embodiment.

[0317] S1302. The terminal device determines a first physical resource for transmitting an uplink reference signal and a second physical resource for transmitting an uplink channel.

[0318] The terminal device can determine the first physical resource and the second physical resource based on the configuration of the network device, as shown in Example 1.

[0319] S1303. The terminal device determines the transmission power of the uplink reference signal and the uplink channel.

[0320] a) In one embodiment, the terminal device may determine the transmit power of the uplink reference signal according to a first power ratio value, which is pre-agreed between the terminal and the network, or obtained by the terminal device according to power information indicated by the network device.

[0321] b) The terminal device determines the expected transmit power of the uplink channel (i.e., the uplink transmit power) according to the agreed transmit power calculation method and the power control parameters configured by the network device as the transmit power of the uplink channel; and then determines the transmit power of the uplink reference signal based on the ratio of the uplink transmit power to the first power, wherein the first power ratio is the transmit power ratio between the uplink reference signal and the uplink channel.

[0322] The expected transmit power may be obtained by using the method described in the aforementioned “Uplink PUSCH Power Control”.

[0323] In the embodiments of the present application, the uplink reference signal does not need to be divided from the uplink channel in terms of power, but rather uses an independent transmit power. The transmit power of the uplink channel is not affected by the superimposed uplink reference signal. The uplink reference signal is superimposed at a certain power ratio, thereby not reducing the power of the uplink channel. In contrast, in Embodiments 1 and 2, the uplink reference signal and the uplink channel share the uplink transmit power.

[0324] For example, assuming that the transmission power of the uplink channel in each OFDM symbol is P1, and the transmission power of the uplink reference signal in each OFDM symbol is P2, then in the symbol containing the uplink reference signal, the transmission power of the terminal device is P1+P2, and in the symbol not containing the uplink reference signal, the transmission power of the terminal device is P1.

[0325] c) If, on the time domain resource where the uplink reference signal is located, the sum of the transmit power of the uplink reference signal and the uplink channel exceeds the maximum transmit power supported by the terminal device, the terminal device may determine the transmit power of the uplink reference signal and the uplink channel by using one of the following reduction methods 1 and 2:

[0326] Reduction method 1: Reduce the transmission power of the uplink reference signal and / or the uplink channel on the first physical resource until the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0327] Among them, only the transmission power of the uplink reference signal or only the transmission power of the uplink channel on the first physical resource can be reduced to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0328] In addition, the transmission power of the uplink reference signal and the uplink channel on the first physical resource may also be reduced simultaneously to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0329] Specifically, the transmission power of the uplink reference signal and the uplink channel on the first physical resource can be reduced in proportion to the second coefficient. That is, the transmission power of the uplink reference signal and the uplink channel is multiplied by the second coefficient to obtain the actual transmission power. The second coefficient is (P max -P1) / (P2+P3), where P max is the maximum transmit power supported by the terminal device, P1 is the total transmit power of the uplink channel on the REs not used for transmitting the uplink reference signal on the time domain resource where the uplink reference signal is located, P2 is the total transmit power of the uplink reference signal on the time domain resource, and P3 is the total transmit power of the uplink channel on the REs used for transmitting the uplink reference signal. Since P1+P2+P3 is greater than or equal to P max , the second coefficient is less than or equal to 1. After the transmit power is reduced based on the second coefficient, the sum of the transmit power of the uplink reference signal and the uplink channel will be equal to the maximum transmit power supported by the terminal device, thereby ensuring the transmit power as much as possible while meeting the above requirements.

[0330] In reduction method 1, only signal transmission on the first physical resource is affected, and other physical resources are not affected, thereby reducing the impact on data transmission.

[0331] Reduction method 2: Reduce the transmission power of the uplink reference signal and / or the uplink channel on the time domain resource where the uplink reference signal is located until the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0332] Only the transmission power of the uplink reference signal can be reduced, or only the transmission power of the uplink channel on the time domain resources (such as on the OFDM symbol) can be reduced to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device.

[0333] In addition, the transmission power of the uplink reference signal and the uplink channel on the time domain resource where the uplink reference signal is located can also be reduced simultaneously to ensure that the sum of the transmission power of the uplink reference signal and the uplink channel does not exceed the maximum transmission power supported by the terminal device. Specifically, the transmission power of the uplink reference signal and the uplink channel on the time domain resource can be reduced in proportion to the third coefficient, that is, the transmission power of the uplink reference signal and the uplink channel is multiplied by the third coefficient to obtain the actual transmission power. The third coefficient is the ratio between the maximum transmission power supported by the terminal device and {the sum of the transmission power of the uplink reference signal and the uplink channel}.

[0334] In one embodiment, the power reduction operation is performed only on the time domain resource where the uplink reference signal is located, and the uplink channels on other time domain resources are not affected and are still transmitted according to the calculated transmit power. In another embodiment, the terminal device uses the (reduced) transmit power of the uplink channel on the time domain resource where the uplink reference signal is located as the transmit power of the uplink channel transmitted on other time domain resources. In other words, the power reduction operation must be performed on all time domain resources occupied by the uplink channel, so as to ensure that the transmit power of the uplink channels on different time domain resources is the same, thereby reducing the detection complexity of the receiving end.

[0335] d) The terminal device reports the first PHR and the second PHR to the network device.

[0336] The first PHR includes the power headroom of the uplink channel on the time domain resource where the uplink reference signal is located, wherein the first transmit power is the sum of the transmit powers of the uplink channel and the uplink reference signal on the time domain resource. In other words, the first PHR takes into account the transmit power of all uplink signals on the time domain resource.

[0337] The second PHR includes the power headroom on the time domain resource where the uplink reference signal is not transmitted. Specifically, the power headroom is the maximum transmit power P supported by the terminal device. maxand the difference between the transmit power of the uplink channel on the corresponding time domain resource.

[0338] S1304. The terminal device sends the uplink reference signal and the uplink channel on the first physical resource and the second physical resource respectively based on the transmission power.

[0339] S1305. The network device receives the uplink reference signal and the uplink channel on the first physical resource and the second physical resource.

[0340] The preferred embodiments of the present application are described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, various simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the scope of protection of the present application.

[0341] FIG22 is a schematic diagram of the structure of a terminal device provided in an embodiment of the present application. As shown in FIG22 , the terminal device 2200 includes:

[0342] The first communication unit 2201 is configured to determine a first physical resource and a second physical resource, where the first physical resource is used to transmit an uplink reference signal, the second physical resource is used to transmit an uplink channel, and the first physical resource is part of the second physical resource;

[0343] The first processing unit 2202 is configured to determine the transmit power of the uplink reference signal and the transmit power of the uplink channel;

[0344] The first communication unit 2201 is further configured to send the uplink reference signal on the first physical resource based on the transmission power of the uplink reference signal, and send the uplink channel on the second physical resource based on the transmission power of the uplink channel.

[0345] In some embodiments, the first processing unit 2202 is further configured to determine the transmit power of the uplink reference signal and the transmit power of the uplink channel based on a first power ratio, wherein the first power ratio is the transmit power ratio between the transmit power of the uplink reference signal and the transmit power of the uplink channel.

[0346] In some embodiments, the first power ratio is one of the following:

[0347] a ratio between the transmit power of the uplink reference signal and the transmit power of the uplink channel in the first physical resource;
