The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments.

[0095] Implementation Methods of the Application

[0096] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0097] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0098] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0099] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0100] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0101] It should be noted that in this article, step codes such as S01 and S02 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order. When implementing the step, those skilled in the art may execute S02 first and then S01, etc., but these should all be within the scope of protection of this application.

[0102] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0103] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0104] The terminal device may be implemented in various forms. For example, the terminal device described in this application may include intelligent terminal devices such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and other fixed terminal devices such as digital TVs and desktop computers.

[0105] The subsequent description will be made using a mobile terminal as an example. Those skilled in the art will understand that, in addition to components specifically used for mobile purposes, the structure according to the embodiments of the present application can also be applied to fixed-type terminal devices.

[0106] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0107] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0108] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0109] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0110] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0111] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0112] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

[0113] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0114] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0115] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0116] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0117] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area.

[0135] First embodiment

[0136] 5 , which is a flow chart of a control method according to a first embodiment, the method of the embodiment of the present application can be applied to a terminal device (such as a mobile phone). The control method includes the following steps:

[0137] S1: Perform physical uplink shared channel power control based on power control parameters.

[0138] In an embodiment of the present application, in a multi-TRP (Transmission / Reception Point) scenario based on a single downlink control information (Downlink Control Information, DCI), that is, RRC configures two sounding reference signal (SRS) resource sets and its usage (egusage) is set to codebook (egcodebook) or non-codebook (egnonCodebook), and / or the value of the SRS resource set indication (egSRS resource set indicator) field in DCI 0_1 / 0_2 is '10' or '11', it can be indicated that the terminal device can communicate with two network devices (egTRP) using two TCI (Transmission Configuration Indication) states, each TCI state corresponds to one network device. Provide the terminal device with two SRS resource sets and / or the power control parameters corresponding to the PUSCH transmission opportunity / repetition (egtransmission occasion / repetition) corresponding to the network device. In an embodiment of the present application, the power control parameter is the PUSCH power (egP o_UE_PUSCH,b,f,c (j)), i.e., the power control parameter, the terminal device can perform power control according to the power control configuration related to different network devices and calculate the PUSCH transmission power sent to it.

[0139] Optionally, the power control parameter is selected or determined based on downlink information. The downlink information includes radio resource control signaling and / or downlink control information; the power control parameter includes a first power control parameter and / or a second power control parameter. The downlink control information includes a transmission configuration indication field and / or an open-loop power control parameter set indication field; and the radio resource control signaling includes at least one of a multiple-input multiple-output information element, an uplink dedicated fractional bandwidth information element, and a power control and backoff factor parameter.

[0140] Optionally, the multiple-input multiple-output information element includes an uplink power control list, a power control value information element list, and / or an open-loop power control parameter set parameter. The uplink power control list includes a first uplink power control list and / or a second uplink power control list; and / or the first uplink power control list includes a first uplink power control information element and / or a second uplink power control information element; and / or the second uplink power control list includes the second uplink power control information element.

[0141] In an optional implementation manner, before the step of performing physical uplink shared channel power control based on the power control parameter, the method further includes:

[0142] S01: Selecting or determining a power control series value parameter and / or a power control and compensation factor parameter according to the downlink information;

[0143] S02: Select or determine the power control parameter from the power control series value parameters and / or power control and compensation factor parameters based on the indication status of the open-loop power control parameter set indication field.

[0144] Optionally, the manner of selecting or determining the power control series value parameter and / or the power control and compensation factor parameter according to the downlink information includes at least one of the following:

[0145] As one implementation method, a new parameter is added to an uplink power control information element (e.g., Uplink-powerControl-r17) or a TCI state (e.g., TCI-State or TCI-UL-State-r17) to indicate the index value of a power control value information element (Information Element). Based on this index value, a power control value information element is found from a list of power control value information elements. This power control value information element includes a power control value information element index value and a power control series value parameter. Optionally, the list of power control value information elements may include M power control value information elements. This power control series value parameter is used to provide a series of power control values, with a maximum number of power control values ​​being N, which is configured by the base station. Optionally, the base station may determine the value of N based on whether the terminal needs to support simultaneous transmission / reception of multiple panels (e.g., panels), whether the terminal needs to support panel-level power control value configuration, the number of bits in the open-loop power control parameter set indication field in the DCI, and whether precise power control value configuration is performed.

[0146] As another implementation, a power control series value parameter is added to the uplink power control information element (e.g., Uplink-powerControl-r17) to provide a series of power control values. The maximum number of power control values ​​is N, which is configured by the base station. Optionally, the base station may determine the value of N based on whether the terminal needs to support simultaneous transmission / reception of multiple panels (e.g., panels), whether the terminal needs to support panel-level power control value configuration, the number of bits in the open-loop power control parameter set indicator field in the DCI, and whether precise power control value configuration is performed.

[0147] By adding a parameter to the uplink power control information element (UPCI) to indicate a range of power control values, the power control value can be directly obtained from the TCI state, thereby enabling power control at the network device level or terminal device panel level. This method is more direct and efficient for obtaining power control values. A specific example is as follows: a power control series value parameter (egp0forPUSCH-r18) is added to the uplink power control information element (UPCI). This parameter is used to provide N power control values, which are all associated with the TCI state through the uplink power control information element index value (egul-powercontrolId-r17).

[0148]

[0149]

[0150] As another embodiment, the power control and compensation factor parameter is a physical uplink shared channel power control and compensation factor parameter) (egp0AlphaSetforPUSCH-r17), which is of the type of a power control and compensation factor set information element (egP0AlphaSet-r17). A power control series value parameter is added to the power control and compensation factor set information element to provide a series of power control values. The maximum number of power control values ​​is N, which is configured by the base station. Optionally, the base station can determine the value of N based on whether the terminal needs to support simultaneous transmission / reception of multiple panels (egpanel), whether the terminal needs to support panel-level power control value configuration, the number of bits of the open-loop power control parameter set indication field in the DCI, and whether precise power control value configuration is performed.

[0151] By adding a parameter to the power control and compensation factor set information element to indicate a series of power control values, these power control values ​​are associated with the TCI state, thereby enabling power control based on the network device level / terminal device panel level. This method can efficiently obtain power control values ​​without adding new information elements. A specific example is as follows: adding a power control series value parameter (egp0forPUSCH-r18) to the power control and compensation factor set information element is used to provide N power control values. These N power control values ​​are associated with the TCI state through the uplink power control information element index value (egul-powercontrolId-r17).

[0152]

[0153] Optionally, the step of selecting or determining the power control parameter from the power control series value parameter and / or the power control and compensation factor parameter based on the indication state of the open-loop power control parameter set indication field includes:

[0154] Add two open-loop power control parameter set parameters (egolpc-ParameterSetDCI-0-1-r18 and olpc-ParameterSetDCI-0-2-r18) to the Multiple-Input Multiple-Output (MIMO) information element (egMIMOParam-r17) to indicate the length of the open-loop power control parameter set indication field in the DCI. Optionally, these two open-loop power control parameter set parameters can be configured together with the power control value. For example, if the power control value information element list (egp0-PUSCH-Lis t-r18) indicates a power control value, then these two open-loop power control parameter set parameters are configured together with the power control value information element list. For another example, if the uplink power control information element directly indicates a power control series value parameter, then these two open-loop power control parameter set parameters are configured together with the power control series value parameter in the uplink power control information element; the values ​​of the parameters olpc-ParameterSetDCI-0-1-r18 and olpc-ParameterSetDCI-0-2-r18 can be 1 or 2, that is, the first preset value or the second preset value, respectively used to indicate the field length of the open-loop power control parameter set indication field in DCI 0_1 and DCI 0_2. Optionally, the base station can configure the values ​​of the open-loop power control parameter set parameters based on whether the terminal needs to support simultaneous transmission / reception of multiple panels (egpanel), whether the terminal needs to support panel-level power control value configuration, whether to perform precise power control value configuration, and whether the TCI status includes the uplink power control information element index value (egul-powerControl-r17).

[0155] If the power control value is configured, the field length of the open-loop power control parameter set indication field in the DCI is determined by the open-loop power control parameter set parameters (egolpc-ParameterSetDCI-0-1-r18 and olpc-ParameterSetDCI-0-2-r18) and / or whether the TCI status includes the uplink power control information element index value (egul-powerControl-r17).

[0156] This embodiment, through the above-mentioned scheme, specifically performs physical uplink shared channel power control based on power control parameters, and provides an open-loop power control process and / or open-loop power control value configuration scheme based on multiple network equipment scenarios, thereby improving the versatility of the power control method.

[0183] Optionally, the method for configuring the power control series value parameters according to the uplink power control list and the power control value information element list includes:

[0184] As one of the implementation methods, a new parameter is added to the uplink power control information element to indicate the power control value information element index value and one uplink power control list and one power control value information element list are configured: a new parameter is added to the uplink power control information element to indicate the power control value information element index value, and one power control value information element list is configured under the multiple-input multiple-output information element (egMIMOParam-r17).

This allows mapping of power control values ​​to TCI states and enables network device-level / UE panel-level power control. Furthermore, this approach reduces signaling overhead. A specific example is as follows: a power control value information element index value (egp0-PUSCHId-r18) parameter is added to the uplink power control information element, a power control value information element list (egp0-PUSCH-List-r18) is added to the MIMO information element, and the power control value information element is found from the power control value information element list based on the index value.

[0186]

[0187]

[0188] Referring to Figure 7, Figure 7 is a schematic diagram of a first example flow chart of a control method according to the second embodiment. When configuring one uplink power control list and one power control value information element list, the mapping relationship between the TCI state and the power control series value parameter is shown in Figure 7. The TCI state applied to the PUSCH transmission opportunity / repetition corresponding to the first SRS resource set and / or network device is the first TCI state. According to the uplink power control information element index value (egul-powercontrolId-r17), the first uplink power control information element is obtained from the uplink power control list, and then a power control value information element index is obtained therefrom. value (egp0-PUSCHId-r18), and according to this index value, obtains the first power control value information element from the power control value information element list (egp0-PUSCH-List-r18), and obtains the first power control series value parameter (egp0forPUSCH-r18) therefrom; similarly, the second SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device also obtains the second uplink power control information element from the same uplink power control list, and then obtains the second power control value information element from the same power control value information element list, and obtains the second power control series value parameter therefrom.

[0189] If the TCI state does not include an uplink power control information element index value, that is, the terminal device cannot obtain the power control value through the uplink power control information element index value associated with the TCI state, a new uplink power control information element index value is added to the uplink dedicated part bandwidth (Bandwidth Part, BWP) information element (egBWP-UplinkDedicated), for a total of 2 uplink power control information element index values. These 2 uplink power control information element index values ​​(egul-powerControl-r17) correspond to two SRS resource sets and / or PUSCH transmission opportunities / repetitions corresponding to the network device, respectively.

[0190] According to the uplink power control information element index value corresponding to the first SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device, the first uplink power control information element is obtained from the uplink power control list, and then a power control value information element index value (egp0-PUSCHId-r18) is obtained therefrom, and according to this index value, the first power control value information element is obtained from the power control value information element list (egp0-PUSCH-List-r18), and the first power control series value parameter (egp0forPUSCH-r18) is obtained therefrom; similarly, according to the uplink power control information element index value corresponding to the second SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device, the second uplink power control information element is obtained from the same uplink power control list, and then the second power control value information element is obtained from the same power control value information element list, and the second power control series value parameter is obtained therefrom.

[0191] As one of the implementation methods, a new parameter is added to the uplink power control information element to indicate the power control value information element index value and one uplink power control list and two power control value information element lists are configured: a new parameter is added to the uplink power control information element to indicate the power control value information element index value and two power control value information element lists are configured under the multi-input multi-output information element.

[0192] If the TCI state includes an uplink power control information element index value, the power control value parameters corresponding to the two SRS resource sets and / or PUSCH transmission opportunities / repetitions corresponding to the network device are provided from the power control value information elements in these two power control value information element lists based on the corresponding TCI state. By configuring two power control value information element lists, one for each of the two SRS resource sets and / or PUSCH transmission opportunities / repetitions corresponding to the network device, the configuration of the power control value information element list corresponding to each SRS resource set and / or PUSCH transmission opportunity / repetition corresponding to the network device is made more independent and flexible. A specific example is as follows: a power control value information element index value parameter (e.g., p0-PUSCHId-r18) is added to the uplink power control information element, and two power control value information element lists (e.g., p0-PUSCH-List-r18 and p0-PUSCH-List2-r18) are added to the multiple-input multiple-output information element.

[0193]

[0194]

[0195] 8 , which is a schematic diagram of a second example flow of a control method according to the second embodiment, a mapping relationship between a TCI state and a power control series value parameter when configuring one uplink power control list and two power control value information element lists is shown in FIG8 . The TCI state applied to the PUSCH transmission opportunity / repetition corresponding to the first SRS resource set and / or network device is the first TCI state. According to the uplink power control information element index value, a first uplink power control information element is obtained from the uplink power control list, and then a power control value information element index value (egp0-PUSCHId-r18) is obtained therefrom. According to this The index value obtains the first power control value information element from the first power control value information element list (egp0-PUSCH-List-r18), and obtains the first power control series value parameter (egp0forPUSCH-r18) therefrom; similarly, the second SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device obtains the second uplink power control information element from the same uplink power control list, and then obtains the second power control value information element from the second power control value information element list (egp0-PUSCH-List2-r18), and obtains the second power control series value parameter therefrom.

[0196] If the TCI state does not include an uplink power control information element index value, a first uplink power control information element is obtained from the uplink power control list according to the uplink power control information element index value corresponding to the first SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device, and then a power control value information element index value (egp0-PUSCHId-r18) is obtained therefrom, and a first power control value information element is obtained from the first power control value information element list (egp0-PUSCH-List-r18) according to this index value, and a first power control series value parameter is obtained therefrom; a second uplink power control information element is obtained from the same uplink power control list according to the uplink power control information element index value corresponding to the second SRS resource set and / or the PUSCH transmission opportunity / repetition corresponding to the network device, and then a second power control value information element is obtained from the second power control value information element list, and a second power control series value parameter is obtained therefrom.

[0197] As one of the implementation methods, a new parameter is added to the uplink power control information element to indicate the power control value information element index value and two uplink power control lists and one power control value information element list are configured: a new parameter is added to the uplink power control information element to indicate the power control value information element index value, an uplink power control list is added under the multiple-input multiple-output information element, for a total of two uplink power control lists, and one power control value information element list is configured.

[0198] By configuring two uplink power control lists, one for each of the two SRS resource sets and / or PUSCH transmission opportunities / repetitions corresponding to the network device, the configuration of the uplink power control lists becomes more independent and flexible.
