However, the following description describes the NR system for example purposes and uses NR terminology in most of the following description, although these techniques can also be applied to applications other than NR system applications.

[0052] See Figure 1 , Figure 1A block diagram of a wireless communication system to which embodiments of the present invention can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device, or a vehicle-mounted device, etc. It should be noted that in the embodiments of the present invention, the specific type of the terminal 11 is not limited. The network-side device 12 can be a base station or a core network. Among them, the above base station can be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access points, etc.), or a location server (for example: E-SMLC or LMF (Location Manager Function)). Among them, the base station can be referred to as Node B, evolved Node B, access point, base transceiver station (Base Transceiver Station, BTS), radio base station, radio transceiver, basic service set (Basic Service Set, BSS), extended service set (Extended Service Set, ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0053] The base station can communicate with the terminal 11 under the control of a base station controller. In various examples, the base station controller can be a part of the core network or some base stations. Some base stations can communicate control information or user data with the core network through a backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly through a backhaul link, and the backhaul link can be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can simultaneously transmit modulated signals on these multiple carriers. For example, each communication link can be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be transmitted on a different carrier and can carry control information (for example, reference signals, control channels, etc.), overhead information, data, etc.

[0054] A base station can communicate wirelessly with a terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of an access point can be divided into sectors that only form a part of the coverage area. A wireless communication system can include different types of base stations (such as macro base stations, micro base stations, or pico base stations). Base stations can also utilize different radio technologies, such as cellular or WLAN radio access technologies. Base stations can be associated with the same or different access network or operator deployments. The coverage areas of different base stations (including the coverage areas of the same or different types of base stations, the coverage areas using the same or different radio technologies, or the coverage areas belonging to the same or different access networks) can overlap.

[0055] Communication links in a wireless communication system can include an uplink for carrying uplink (UL) transmissions (e.g., from the terminal 11 to the network-side device 12), a downlink for carrying downlink (DL) transmissions (e.g., from the network-side device 12 to the terminal 11), and a sidelink (SL, or also translated as secondary link, side link, edge link, etc.) for carrying transmissions between terminals 11. UL transmissions can also be referred to as reverse link transmissions, while DL transmissions can also be referred to as forward link transmissions. Downlink transmissions can be carried out using an authorized frequency band, an unlicensed frequency band, or both. Similarly, uplink transmissions can be carried out using an authorized frequency band, an unlicensed frequency band, or both.

[0056] For a Physical Uplink Shared Channel (PUSCH) transmission, a terminal (User Equipment, UE) calculates a transmission power P PUSCH,b,f,c (i,j,q d ,l) of a linear value

[0057] For a PUSCH transmission scheduled by Downlink Control Information (DCI) or configured by an information element (IE) ConfiguredGrantConfig or IE semiPersistentOnPUSCH, when the field txConfig in IE PUSCH-Config is set to 'codebook',

[0058] 1) If the radio resource control (RRC) parameter ULFPTx is in IE PUSCH-config and the codebookSubset in IE PUSCH-Config is set to nonCoherent or partialAndNonCoherent, the user scales the scaling by parameter s, where,

[0059] <1-1> If the ULFPTxModes in IE PUSCH-Config is set to Mode1, each sounding reference signal (SRS) resource in SRS-ResourceSet that is set to codebook has multiple SRS ports, and the power scaling factor s is equal to the ratio of the number of antenna ports with non-zero PUSCH transmission power to the maximum number of SRS ports supported by the UE in one SRS resource.

[0060] <1-2> If the ULFPTxModes in IE PUSCH-Config is set to Mode2,

[0061] <1-2-1> When full power TPMIs are reported by the UE, the power scaling factor s of the corresponding broadband transmitted precoding matrix indicator (TPMI) is equal to 1, and the power scaling factor s of other TPMIs is equal to the ratio of the number of antenna ports with non-zero PUSCH transmission power to the number of SRS ports. If multiple SRS resources are configured in the SRS resource set and these SRS resources are set to "codebook", the number of SRS ports is associated with one SRS resource, which is indicated by the SRS resource indicator (SRI). Or, if one SRS resource is configured in the SRS resource set and this SRS resource is set to "codebook", the number of SRS ports is associated with this SRS resource.

[0062] <1-2-2>When the full power TPMIs are not reported by the UE, the power scaling factor s is equal to the ratio of the number of antenna ports with non-zero PUSCH transmission power to the number of SRS ports, where the number of SRS ports is associated with an SRS resource. If multiple SRS resources are configured in the SRS resource set and these SRS resources are set to "codebook", the SRS resource is indicated by the SRI, and the indicated SRS resource has multiple SRS ports.

[0063] <1-3>If the power scaling mode is not configured in the IE PUSCH-Config, the power scaling factor s is equal to 1.

[0064] 2) In other cases, if each SRS resource set to 'codebook' in the SRS resource set has multiple SRS ports, the UE scales by the ratio of the maximum number of SRS ports supported by the UE in an SRS resource to the number of antenna ports with non-zero PUSCH transmission power.

[0065] The UE evenly distributes the power among the antenna ports for non-zero power transmission PUSCH.

[0066] The basic framework of UE uplink power control includes an open-loop power control part and a closed-loop power control part, and the calculation formulas are as follows:

[0067]

[0068] The open-loop power control part consists of P O_PUSCHb,,f,c (j), α b,f,c (j), PL b,f,c (q d ), where P O_PUSCHb,,f,c (j) represents the open-loop receiving end power target value. The larger the target value, the higher the uplink transmission power usually is; α b,f,c (j) is the partial path loss compensation factor, and its value range is between 0 and 1; PL b,f,c (q d ) is the path loss estimation, which is estimated through the downlink reference signal.

[0069] The closed-loop power control part consists of f b,f,c (i, l), which represents the power control adjustment status value and can quickly adjust the transmission power for a certain transmission of a certain UE,

[0070] Other adjustment amounts are mainly Δ TF,b,f,c (i) and It is closely related to resource allocation and link adaptation. Regarding the bandwidth allocated for uplink transmission, when the subcarrier spacing is 15 kHz, its value is equal to the number of Physical Resource Blocks (PRBs). Δ TF,b,f,c (i) is an adjustment amount related to the uplink transmission Modulation and Coding Scheme (MCS),

[0071] Transmission power P CMAX,f,c (i) It is the maximum transmit power of the UE and is related to the Power Class.

[0072] The above power scaling mode does not combine well with the power control process of the terminal's radio frequency architecture and cannot guarantee the uplink transmission performance of the terminal.

[0073] An embodiment of the present invention provides an uplink transmission method applied to a terminal, such as Figure 2 shown, including:

[0074] Step 101: Receive power control parameters indicated by a network-side device, where the power control parameters are configured based on at least one of the following:

[0075] Transmitted layer;

[0076] Transmitted rank;

[0077] Transmitted port;

[0078] Transmitted layer group;

[0079] Transmitted rank group;

[0080] Transmitted port group;

[0081] Step 102: Perform uplink transmission according to the power control parameters.

[0082] In this embodiment, the network-side device can configure power control parameters for the terminal based on at least one of the transmitted layer, rank, port, layer group, rank group, and port group, which can improve the uplink transmission quality of the terminal and minimize interference to other users of the system.

[0083] In some embodiments, the power control parameters include any one of the following:

[0084] Power scaling mode or Uplink Full Power Transmission Modes (ULFPTxModes) based on the configured layer for transmission;

[0085] Power scaling mode or Uplink Full Power Transmission Modes (ULFPTxModes) based on the configured layer group for transmission.

[0086] In this way, the network - side device can configure the power scaling mode or ULFPTxModes more flexibly based on the layer or layer group, so as to maximize the utilization of the terminal's radio frequency architecture. The terminal obtains the corresponding power scaling factor (s) through the corresponding power control parameters (power scaling mode or ULFPTxModes), thereby achieving uplink full - power transmission. Since the network - side device can configure the power scaling mode and ULFPTxModes more flexibly, the terminal can appropriately increase the rated power of some PAs, so that when transmitting for a specific layer or rank or port or layer group or rank group or port group, it can support a larger power class, that is, transmit with a larger transmission power.

[0087] In some embodiments, the power control parameters include at least one of the following:

[0088] The maximum transmit power P of the terminal based on the configured layer for transmission CMAX,f,c (i);

[0089] The open - loop receive - end power target value P O_PUSCHb,,f ,c(j);

[0090] The partial path - loss compensation factor α b,f,c (j);

[0091] The path - loss estimation PL b,f,c (q d );

[0092] The power control adjustment status value f b,f,c (i,l);

[0093] The adjustment amount Δ related to the uplink transmission modulation and coding strategy (MCS) based on the configured layer for transmission TF,b,f,c (i);

[0094] P based on the configured transmission layer group CMAX,f,c (i);

[0095] P based on the configured transmission layer group O_PUSCHb,,f,c (j);

[0096] α based on the configured transmission layer group b,f,c (j);

[0097] PL based on the configured transmission layer group b,f,c (q d );

[0098] f based on the configured transmission layer group b,f,c (i, l);

[0099] Δ based on the configured transmission layer group TF,b,f,c (i).

[0100] Through the above power control parameters, the terminal can obtain a more accurate power control value, reduce the power consumption of the terminal, and extend the usage time of the terminal.

[0101] In some embodiments, the power control parameters are carried in at least one of the following signaling:

[0102] Radio Resource Control (RRC) message;

[0103] Medium Access Control (MAC) Control Element (CE);

[0104] Downlink Control Information (DCI).

[0105] In some embodiments, before receiving the power control parameters of the network side device, the method further includes:

[0106] Reporting the power level Power Class to the network side device, where the Power Class is related to at least one of the following: layer; rank; port; layer group; rank group; port group.

[0107] This embodiment supports the terminal to report the power class based on at least one of the transmitted layer, rank, port, layer group, rank group, and port group. In this way, the network-side device can configure different power scaling modes based on at least one of the layer, rank, port, layer group, rank group, and port group and the corresponding power class, which can better support the terminal to transmit at full power and maximize the utilization of the terminal radio frequency architecture. The network-side device can also configure the maximum transmit power P of the terminal based on at least one of the layer, rank, port, layer group, rank group, and port group and the corresponding power class CMAX,f,c (i), open-loop receive-end power target value P O_PUSCHb,,f,c (j), partial path loss compensation factor α b,f,c (j), path loss estimation PL b,f,c (q d ), power control adjustment status value f b,f,c (i, l) and the adjustment amount Δ related to the uplink transmission modulation and coding strategy MCS TF,b,f,c (i) at least one of the power control parameters to calculate the uplink transmit power more accurately and improve the uplink transmission performance

[0108] This embodiment of the present invention also provides an uplink transmission method applied to a network-side device, as Figure 3 shown, including:

[0109] Step 201: Send power control parameters for uplink transmission to the terminal, where the power control parameters are configured based on at least one of the following:

[0110] Transmitted layer layer;

[0111] Transmitted rank rank;

[0112] Transmitted port port;

[0113] Transmitted layer group layer group;

[0114] Transmitted rank group rank group;

[0115] Transmitted port group port group

[0116] In this embodiment, the network-side device can configure power control parameters for the terminal based on at least one of the transmitted layer, rank, port, layer group, rank group, and port group, which can improve the uplink transmission quality of the terminal and minimize interference to other users in the system.

[0117] In some embodiments, the power control parameter includes any one of the following:

[0118] The power scaling mode or the uplink full power transmission mode (ULFPTxModes) configured based on the transmitted layer;

[0119] The power scaling mode or the uplink full power transmission mode (ULFPTxModes) configured based on the transmitted layer group.

[0120] In this way, the network-side device can configure the power scaling mode or ULFPTxModes more flexibly based on the layer or layer group, so as to maximize the utilization of the terminal's radio frequency architecture. The terminal obtains the corresponding power scaling factor (s) through the corresponding power control parameter (power scaling mode or ULFPTxModes), so as to achieve uplink full power transmission. Since the network-side device can configure the power scaling mode and ULFPTxModes more flexibly, the terminal can appropriately increase the rated power of some PAs, so that a larger power class can be supported when transmitting for a specific layer or rank or port or layer group or rank group or port group, that is, transmit with a larger transmission power.

[0121] In some embodiments, the power control parameter further includes at least one of the following:

[0122] The maximum transmit power P of the terminal configured based on the transmitted layer CMAX,f,c (i);

[0123] The open-loop receiver power target value P configured based on the transmitted layer O_PUSCHb,,f,c (j);

[0124] The partial path loss compensation factor α configured based on the transmitted layer b,f,c (j);

[0125] The path loss estimate PL configured based on the transmitted layer b,f,c (q d )

[0126] Power control adjustment status value f based on the transmitted layer configuration b,f,c (i, l);

[0127] Adjustment amount Δ related to the uplink transmission modulation and coding strategy MCS based on the transmitted layer configuration TF,b,f,c (i);

[0128] P based on the transmitted layer group configuration CMAX,f,c (i);

[0129] P based on the transmitted layer group configuration O_PUSCHb,,f,c (j);

[0130] α based on the transmitted layer group configuration b,f,c (j);

[0131] PL based on the transmitted layer group configuration b,f,c (q d );

[0132] f based on the transmitted layer group configuration b,f,c (i, l);

[0133] Δ based on the transmitted layer group configuration TF,b,f,c (i).

[0134] Through the above power control parameters, the terminal can obtain a more accurate power control value, reduce the power consumption of the terminal, and extend the usage time of the terminal.

[0135] In some embodiments, the power control parameters are carried in at least one of the following signaling:

[0136] RRC message;

[0137] MAC CE;

[0138] DCI.

[0139] In some embodiments, before sending the power control parameters for uplink transmission to the terminal, the method further includes:

[0140] Receiving the power class reported by the terminal, where the power class is related to at least one of the following: layer; rank; port; layer group; rank group; port group.

[0141] This embodiment supports the terminal to report the power class based on at least one of the transmitted layer, rank, port, layer group, rank group, and port group. In this way, the network-side device can configure different power scaling modes based on at least one of the layer, rank, port, layer group, rank group, and port group and the corresponding power class, which can better support the terminal to transmit at full power and maximize the utilization of the terminal radio frequency architecture. The network-side device can also configure the maximum transmit power P of the terminal based on at least one of the layer, rank, port, layer group, rank group, and port group and the corresponding power class CMAX,f,c (i), open-loop receive-end power target value P O_PUSCHb,,f,c (j), partial path loss compensation factor α b,f,c (j), path loss estimation PL b,f,c (q d ), power control adjustment status value f b,f,c (i, l) and the adjustment amount Δ related to the uplink transmission modulation and coding strategy MCS TF,b,f,c (i) at least one of the power control parameters, to calculate the uplink transmit power more accurately and improve the uplink transmission performance.

[0142] The uplink transmission method of the present invention will be further introduced below in conjunction with specific embodiments:

[0143] Embodiment 1

[0144] In this embodiment, as Figure 4 shown, a schematic diagram of the radio frequency architecture of a 4-port terminal is given. The terminal can report different power levels (Power Class, PC) based on different numbers of transmitted layers to maximize the uplink transmission performance. Among them, PA is the power amplifier, and 23dBm and 20dBm at the PA port are the maximum powers of the PA. Assume that

[0145] (1) For 1 layer, the terminal reports Power Class 3: 23dBm;

[0146] (2) For 2 layers, the terminal reports Power Class 2: 26dBm;

[0147] (3) For 3 layers, the terminal reports Power Class 3: 23dBm;

[0148] (4) For 4 layers, the terminal reports Power Class 2: 26 dBm;

[0149] When the RRC parameter ULFPTx is configured for full power transmission, in different Power Class cases, corresponding to different numbers of transmission layers, the network side device can indicate different power control parameters and power scaling modes, which may be specifically as follows:

[0150] (1) For 1 layer, when the terminal reports Power Class 3, the network side device may not configure the power scaling mode in PUSCH-Config, P CMAX,f,c (i) Determined based on PC3;

[0151] (2) For 2 layers, when the terminal reports Power Class 2, the network side device may configure ULFPTxModes = mode2 or ULFPTxModes = mode1, P CMAX,f,c (i) Determined based on PC2;

[0152] (3) For 3 layers, when the terminal reports Power Class 3, the network side device may not configure the power scaling mode in PUSCH-Config, P CMAX,f,c (i) Determined based on PC3;

[0153] (4) For 4 layers, when the terminal reports Power Class 2, the network side device may configure ULFPTxModes = mode2 or ULFPTxModes = mode1, P CMAX,f,c (i) Determined based on PC2;

[0154] Embodiment 2

[0155] In this embodiment, as Figure 5 shown, a schematic diagram of the radio frequency architecture of a 4-port terminal is given. The terminal can report different Power Classes based on different numbers of transmission layers to maximize the uplink transmission performance. Assume that,

[0156] (1) For 1 layer, the terminal reports Power Class 3: 23 dBm;

[0157] (2) For 2 layers, the terminal reports Power Class 3: 23 dBm;

[0158] (3) For 3 layers, the terminal reports Power Class 3: 23 dBm;

The terminal 40 includes, but is not limited to: a radio frequency unit 41, a network module 42, an audio output unit 43, an input unit 44, a sensor 45, a display unit 46, a user input unit 47, an interface unit 48, a memory 49, a processor 410, and a power supply 411, etc. Those skilled in the art can understand that Figure 11 the terminal structure shown in does not constitute a limitation on the terminal. The terminal may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. In the embodiments of the present invention, the terminal includes, but is not limited to, mobile phones, tablet computers, laptop computers, handheld computers, vehicle-mounted terminals, wearable devices, and pedometers, etc.

[0224] Among them, the processor 410 receives the power control parameters indicated by the network-side device through the radio frequency unit 41. The power control parameters are configured based on at least one of the following: the transmitted layer layer; the transmitted rank rank; the transmitted port port; the transmitted layer group layer group; the transmitted rank group rank group; the transmitted port group port group; and performs uplink transmission according to the power control parameters.

[0225] It should be understood that in the embodiments of the present invention, the radio frequency unit 41 can be used for receiving and sending information or signals during a call. Specifically, after receiving the downlink data from the base station, it is given to the processor 410 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 41 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. In addition, the radio frequency unit 41 can also communicate with the network and other devices through a wireless communication system.

[0226] The network module 42 provides the terminal with wireless broadband Internet access, such as helping the user to send and receive e-mails, browse web pages, and access streaming media, etc.

[0227] The audio output unit 43 can convert the audio data received by the radio frequency unit 41 or the network module 42 or stored in the memory 49 into an audio signal and output it as sound. Moreover, the audio output unit 43 can also provide an audio output related to the specific functions executed by the terminal 40 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 43 includes a speaker, a buzzer, and a receiver, etc.

[0228] The input unit 44 is used for receiving audio or video signals. The input unit 44 can include a Graphics Processing Unit (GPU) 441 and a microphone 442. The graphics processor 441 processes the image data of the static pictures or videos obtained by an image capturing device (such as a camera) in a video capture mode or an image capture mode. The processed image frames can be displayed on the display unit 46. The image frames processed by the graphics processor 441 can be stored in the memory 49 (or other storage media) or sent via the radio frequency unit 41 or the network module 42. The microphone 442 can receive sounds and can process such sounds into audio data. The processed audio data can be converted into a format that can be sent to the mobile communication base station via the radio frequency unit 41 in the case of a phone call mode and output.

[0229] The terminal 40 also includes at least one sensor 45, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor. Among them, the ambient light sensor can adjust the brightness of the display panel 461 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 461 and / or the backlight when the terminal 40 is moved to the ear. As a kind of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity, and can be used to identify the terminal posture (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration), vibration recognition related functions (such as pedometer, tapping), etc.; the sensor 45 can also include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which will not be elaborated here.

The display unit 46 may include a display panel 461, and the display panel 461 can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc.

[0231] The user input unit 47 can be used to receive input digital or character information, and generate key signal inputs related to the user settings and function control of the terminal. Specifically, the user input unit 47 includes a touch panel 471 and other input devices 472. The touch panel 471, also known as a touch screen, can collect the touch operations of the user on or near it (such as the operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch panel 471). The touch panel 471 can include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 410, and receives and executes the commands sent by the processor 410. In addition, the touch panel 471 can be implemented in multiple types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 471, the user input unit 47 can also include other input devices 472. Specifically, the other input devices 472 can include but are not limited to a physical keyboard, function keys (such as volume control keys, power on / off keys, etc.), a trackball, a mouse, a joystick, which will not be elaborated here.

[0232] Further, the touch panel 471 may cover the display panel 461. After the touch panel 471 detects a touch operation on or near it, it transmits the operation to the processor 410 to determine the type of touch event. Subsequently, the processor 410 provides a corresponding visual output on the display panel 461 according to the type of touch event. Although in Figure 11 , the touch panel 471 and the display panel 461 are implemented as two independent components to realize the input and output functions of the terminal, in some embodiments, the touch panel 471 and the display panel 461 may be integrated to realize the input and output functions of the terminal, and specific details are not limited herein.

The interface unit 48 can be used to receive inputs from an external device (such as data information, power, etc.) and transmit the received inputs to one or more components within the terminal 40 or can be used to transfer data between the terminal 40 and the external device.

[0234] The memory 49 can be used to store software programs and various data. The memory 49 mainly includes a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.). In addition, the memory 49 may include a high-speed random access memory and may also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other non-volatile solid-state storage devices.

[0235] The processor 410 is the control center of the terminal. It uses various interfaces and lines to connect all parts of the entire terminal. By running or executing software programs and / or modules stored in the memory 49 and calling data stored in the memory 49, it executes various functions of the terminal and processes data, thereby monitoring the terminal as a whole. The processor 410 may include one or more processing units; preferably, the processor 410 may integrate an application processor and a modem processor. Among them, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It can be understood that the above-mentioned modem processor may not be integrated into the processor 410 either.

[0236] The terminal 40 may further include a power source 411 (such as a battery) for powering each component. Preferably, the power source 411 may be logically connected to the processor 410 through a power management system, so as to implement functions such as management of charging, discharging, and power consumption management through the power management system.

[0237] In addition, the terminal 40 includes some functional modules not shown, which will not be elaborated here.

The terminal obtains the corresponding power scaling factor (power scaling factor) s through the corresponding power control parameters (power scaling mode or ULP Tx Modes), so as to achieve full-power uplink transmission. Since the network-side device can configure the power scaling mode and ULP Tx Modes more flexibly, the terminal can appropriately increase the rated power of some PAs, so that when transmitting for a specific layer or rank or port or layer group or rank group or port group, it can support a larger power class, that is, transmit at a larger transmission power.
