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.

[0113] It should be noted that, in this document, the terms "comprises", "includes" 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 "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element, and / or, 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.

[0114] 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.

[0115] 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.

[0116] 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.

When implementing the step, those skilled in the art may execute S2 first and then S1, etc., but these should all be within the scope of protection of this application.

[0118] 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.

[0119] 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.

Those skilled in the art will understand that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminal devices.

[0123] 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.

[0124] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0125] 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 / or other components. 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), 5G and 6G, etc.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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 here.

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 corresponding connected devices 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 and execute commands sent by the processor 110. And / or, 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.

[0132] 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.

[0134] 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. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, / or, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0135] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0136] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.

[0377] Optionally, the first reference sub-configuration is a sub-configuration with the largest number of ports among all sub-configurations.

[0378] Optionally, for type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, the codebook configuration of the sub-configuration with a port number of 2 associated with the same CSI-RS resource is uniquely configured by the i2 codebook subset restriction of the type 1 single panel (corresponding to the high-level parameter typeI-Singlepanel-codebookSubsetRestriction-i2), that is, for such scenario, the codebook configuration of the sub-configuration with a port number of 2 is not related to the high-level parameters n1-n2, nor to the codebook subset restriction of the two transmit antennas (such as the high-level parameter twoTX-CodebookSubsetRestriction).

The second and third rows are the panels used for the remaining subconfigurations except the first reference subconfiguration, respectively. The panel indices used in the second row of subconfigurations are offset by 1 from the index of the panels used in the first reference subconfiguration. Therefore, the panel indices used in the second row of subconfigurations are Panel #(1+1) and Panel #(2+1). The panel indices used in the second row of subconfigurations are offset by 2 from the index of the panels used in the first reference subconfiguration. Therefore, the panel indices used in the second row of subconfigurations are Panel #(1+2) and Panel #(2+2).

[0430] Optionally, assume that the spatial domain adaptation scenario is Type 1, the number of sub-configurations is 3, and the number of CSI-RS antenna ports corresponding to the three sub-configurations is 32 ports, 16 ports, and 8 ports, respectively; the resource identifiers of the two CSI-RSs simultaneously associated with the three sub-configurations are {1, 2}; assume that the sub-configuration with 32 ports is the first reference sub-configuration, then the power control offset values ​​associated with the three sub-configurations are {-3, 2, 4} dB, respectively, where -3 is the actual power control offset value of the 32-port sub-configuration, and {2, 4} are the differences between the actual power offset values ​​of the 16-port and 8-port sub-configurations and the actual power control offset value of the first reference sub-configuration, that is, the actual power control offset values ​​of the three sub-configurations are {-3dB, -1dB = (2-3) dB, 1dB = (4-3) dB}, respectively; the 3 sub-configurations The codebook type is typeI-MultiPanel, and the parameters ng-n1-n2 corresponding to the three sub-configurations are four-two-two-TypeI-Multipanel-Restriction=25 (hexadecimal number), four-two-one-TypeI-Multipanel-Restriction=48 (hexadecimal number), and two-two-one-TypeI-Multipanel-Restriction=27 (hexadecimal number); the rank indication restrictions (corresponding to the parameter ri-Restriction) corresponding to the three sub-configurations are {'1111', '0111', '0111'} respectively. See Figure 17 for details.

[0431] Optionally, each of the sub-configurations is associated with a panel identifier.

[0432] Optionally, the panel identifier corresponds to a bit value for each panel associated with each sub-configuration; for example, if the number of bits occupied by the panel identifier is 4, then the bit "1111" represents that the current configuration uses all 4 panels; the bit "0110" represents that the current configuration only uses panel #2 and panel #3.

[0433] Alternatively, assuming that the number of panels in both the 32-port and 16-port subconfigurations is 4 and the panel indication is "1111," the 16-port subconfiguration occupies the same four panels as the 32-port subconfiguration. If the number of panels in the 8-port subconfiguration is 2 and the panel indication is "0110," the 8-port subconfiguration occupies two panels, namely Panel #2 and Panel #3. The panels occupied by each subconfiguration are shown in Figure 16. Each slash in Figure 16 corresponds to the polarization direction of an antenna port. In Figure 16, the available antenna ports in the applicable panels for each subconfiguration are those within the solid-line box. Antenna ports outside the solid-line box are unused for that subconfiguration.

[0434] Optionally, when the codebook type is typeI-MultiPanel, the values ​​of N1, N2, O1, and O2 in the codebook configuration of each sub-configuration are different, but N1, N2, O1, and O2 conform to the definition in Table 2 above.

[0435] Through the technical solution of this embodiment, the network device can determine the effective configuration of the configuration elements of each sub-configuration in the Type 1 spatial domain adaptation scenario based on the characteristics of the Type 1 spatial domain adaptation scenario, and the terminal device receives the sub-configuration to generate or determine a channel state information report based on the sub-configuration; optionally, the panel corresponding to each sub-configuration in the Type 1 spatial domain adaptation scenario is determined by bit mapping. Compared with the sixth embodiment, the panel call is more flexible, which facilitates the network to configure a reasonable transmission antenna panel for each sub-configuration based on the current channel environment.

[0449] Optionally, for the Type 1 spatial domain adaptation scenario, at least one of N1, N2, O1, and O2 associated with each subconfiguration is different. For example, if there are two subconfigurations, namely subconfiguration #1 and subconfiguration #2, then the values ​​of {N1, N2, O1, O2} of subconfiguration #1 are different from the values ​​of {N1, N2, O1, O2} of subconfiguration #2, that is, the value of N1 of subconfiguration #1 is different from the value of N1 of subconfiguration #2 and / or the value of N2 of subconfiguration #2 is different from the value of N2 of subconfiguration #2 and / or the value of O1 of subconfiguration #1 is different from the value of O1 of subconfiguration #2 and / or the value of O2 of subconfiguration #1 is different from the value of O2 of subconfiguration #2.

[0450] Optionally, if the number of CSI-RS ports corresponding to the sub-configuration is 2, the i2 codebook subset of the type 1 single panel limits the available codebooks of the sub-configuration.

[0451] Optionally, the first reference sub-configuration is a sub-configuration with the largest number of ports among all sub-configurations.

[0452] Optionally, for type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, the codebook configuration of the sub-configuration with a port number of 2 associated with the same CSI-RS resource is uniquely configured by the i2 codebook subset restriction of the type 1 single panel (corresponding to the high-level parameter typeI-Singlepanel-codebookSubsetRestriction-i2), that is, for such scenario, the codebook configuration of the sub-configuration with a port number of 2 is not related to the high-level parameters n1-n2, nor to the codebook subset restriction of the two transmit antennas (such as the high-level parameter twoTX-CodebookSubsetRestriction).

[0453] Optionally, for type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, when the codebook configuration of the sub-configuration with the number of ports of 2 associated with the same CSI-RS resource is configured, N1, N2, O1, and O2 satisfy N1=N2=O1=O2=1.

[0454] Optionally, the power control offset value includes at least one of the following: a difference from a common power control offset value of all sub-configurations, a difference from a power control offset value of a first reference sub-configuration, and an actual power control offset value of each sub-configuration.

[0455] Optionally, for the type 1 spatial domain adaptation scenario, when the codebook type is type 1 multi-panel, the panels associated with each sub-configuration are not exactly the same.

[0456] Optionally, each of the sub-configurations is associated with a panel identifier.

[0457] Optionally, the panel identification includes at least one of the following:

[0458] Each panel associated with each subconfiguration corresponds to a bit value;

[0459] The index offset value of the first panel associated with each subconfiguration from the first panel of the first reference subconfiguration; for example, as shown in FIG10 , the first row is the panels used in the first reference subconfiguration, and the panel indexes are Panel #1 to Panel #4; the second and third rows are the panels used in the subconfigurations other than the first reference subconfiguration, respectively. The panel indexes used in the second row of subconfigurations are offset by 1 from the indexes used in the first reference subconfiguration, so the panel indexes used in the second row of subconfigurations are Panel #(1+1) and Panel #(2+1); the panel indexes used in the second row of subconfigurations are offset by 2 from the indexes used in the first reference subconfiguration, so the panel indexes used in the second row of subconfigurations are Panel #(1+2) and Panel #(2+2);

[0460] Each sub-configuration is evenly distributed between multiple panels.

[0461] The following are some examples of scenarios:

[0462] Optionally, for a type 1 spatial domain adaptation scenario, the number of antenna ports of the CSI-RS resources corresponding to each sub-configuration in a channel state information reference signal resource set is different.

[0463] Optionally, each spatial domain adaptation mode corresponds to a sub-configuration.

[0466] Optionally, the rank indication restrictions associated with each sub-configuration are not exactly the same.

[0467] Optionally, all sub-configurations are associated with the same codebook type.

[0468] Optionally, each of the sub-configurations is associated with a first codebook configuration.

[0469] Optionally, for type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, the codebook configuration of the sub-configuration with a port number of 2 associated with the same CSI-RS resource is uniquely configured by the i2 codebook subset restriction of the type 1 single panel (corresponding to the high-level parameter typeI-Singlepanel-codebookSubsetRestriction-i2), that is, the codebook configuration of the sub-configuration with a number of 2 ports for such scenarios is not related to the high-level parameters n1-n2, nor to the codebook subset restriction of the two transmit antennas (such as the high-level parameter twoTX-CodebookSubsetRestriction).

[0470] Optionally, for type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, when the codebook configuration of the sub-configuration with the number of ports of 2 associated with the same CSI-RS resource is configured, N1, N2, O1, and O2 satisfy N1=N2=O1=O2=1.

[0471] Optionally, the values ​​of N1, N2, O1, and O2 in the codebook configuration of each sub-configuration are different, but N1, N2, O1, and O2 conform to the definition in Table 1 above.

[0472] Optionally, assume that the spatial domain adaptation scenario is Type 1, the number of sub-configurations is 3, and the number of CSI-RS antenna ports corresponding to the three sub-configurations is 32 ports, 16 ports, and 2 ports, respectively; the resource identifiers of the two CSI-RSs simultaneously associated with the three sub-configurations are {1, 2}; assume that the sub-configuration with 32 ports is the first reference sub-configuration, then the power control offset values ​​associated with the three sub-configurations are {-3, 2, 4}, respectively, where -3 is the actual power control offset value of the 32-port sub-configuration, and {2, 4} are the differences between the actual power offset values ​​of the 16-port and 8-port sub-configurations and the actual power control offset value of the first reference sub-configuration, that is, the actual power control offset values ​​of the three sub-configurations are {-3dB, -1dB = (2-3)dB, 1dB = (4-3)dB}, respectively; the codebook types of the three sub-configurations are all typeI-Singlepanel, 32 ports The parameters n1-n2 corresponding to the sub-configuration and the 16-port sub-configuration are eight-two-typeI-Singlepanel-Restriction = 25 (hexadecimal) and four-two-typeI-Singlepanel-Restriction = 48 (hexadecimal), respectively. The parameters typeI-Singlepanel-codebookSubsetRestriction-i2 for the type 1 single panel i2 codebook subset restriction corresponding to the three sub-configurations are 5 (hexadecimal), 7 (hexadecimal), and 2 (hexadecimal), respectively. The rank indication restriction (corresponding to the parameter ri-Restriction) corresponding to the three sub-configurations is {'1111', '0111', '0111'}, respectively. See Figure 18 for details.

[0473] Optionally, the codebook corresponding to the 2-port sub-configuration in this embodiment is limited only by the i2 codebook subset restriction of the type 1 single panel (corresponding to the high-level parameter typeI-Singlepanel-codebookSubsetRestriction-i2).

[0474] Optionally, for a type 1 spatial domain adaptation scenario, if the number of ports of the first reference subconfiguration is greater than or equal to 4, the codebook configuration of the subconfiguration with a port number of 2 associated with the same CSI-RS resource is uniquely configured by the i2 codebook subset restriction of the type 1 single panel (corresponding to the high-level parameter typeI-Singlepanel-codebookSubsetRestriction-i2). That is, the codebook configuration of the subconfiguration with a port number of 2 in this scenario is independent of the high-level parameters n1-n2 and the two transmit antenna codebook subset restriction (such as the high-level parameter twoTX-CodebookSubsetRestriction).

[0475] Optionally, the configuration of the 2-port sub-configuration by the i2 codebook subset restriction of the type 1 single panel is applicable only when codebookMode = 1 and N1 = N2 = O1 = O2 = 1. The values ​​of the i2 codebook subset restriction for the type 1 single panel correspond to the following Tables 3 and 4.

[0476] Table 3: Codebook for Layer 1 CSI reporting using antenna ports 3000 to 2999 + P_CSI-RS

[0477] Table 4: Codebook for Layer 2 CSI reporting using antenna ports 3000 to 2999 + P_CSI-RS

[0478] in: v l,m =1;

[0479] Optionally, when the codebook type is typeI-Singlepanel, the codebook configuration of the sub-configuration with the number of antenna ports greater than or equal to 4 refers to the 38.214 protocol.

[0480] Through the technical solution of this embodiment, the network device can determine the valid configuration of the configuration elements of each sub-configuration in the type 1 spatial domain adaptation scenario according to the characteristics of the type 1 spatial domain adaptation scenario, and the terminal device receives the sub-configuration to generate or determine a channel state information report based on the sub-configuration; optionally, in the type 1 spatial domain adaptation scenario, if the number of ports of the first reference sub-configuration is greater than or equal to 4, and the number of ports of at least one sub-configuration is 2, the 2-port neutron configuration is configured through the i2 codebook subset restriction of the type 1 single panel; compared with using new and different RRC parameters to configure the 2-port configuration, the consistency of the codebook configurations of multiple sub-configurations can be guaranteed, avoiding the terminal from confusing the codebook configuration parameters of the 2-port sub-configuration when receiving the codebook configuration parameters; thereby ensuring the rationality of network device scheduling.

[0494] For the configuration principles of this embodiment, please refer to the above embodiments and will not be repeated here.

[0495] Through the technical solution of the present application, the network device can determine the configuration elements of each sub-configuration corresponding to different spatial domain adaptation modes based on the spatial domain adaptation category, and can also realize the effective configuration of the configuration elements of each determined sub-configuration, for example, all sub-configurations are associated with the same number of reports, reporting frequency configuration and / or codebook type. Thus, the network device determines and sends at least one sub-configuration that meets the preset conditions according to the specified spatial domain adaptation scenario category, and the terminal device receives at least one sub-configuration that meets the preset conditions to generate or determine a channel state information report based on the sub-configuration, so that the terminal device performs CSI measurement on different spatial domain adaptation scenarios based on different sub-configurations, thereby facilitating the network device (such as a base station) to adjust the number and power of transmission ports of the physical downlink shared channel in real time according to the network energy saving requirements and the CSI measurement results in different spatial domain adaptation scenarios, so as to ultimately achieve network energy saving.

Optionally, the terminal device determines or generates a channel state information report based on the sub-configuration, and the terminal device reports the channel state information report.

[0502] As a result, the network device determines at least one sub-configuration that meets the preset conditions based on the specified spatial domain adaptation scenario category and sends the sub-configuration. The terminal device receives at least one sub-configuration that meets the preset conditions and performs CSI measurement and reporting based on the sub-configuration. This solves the problem of how to configure sub-configurations related to the spatial domain and power domain in Type 1 SD adaptation and Type 2 SD adaptation scenarios, thereby enabling terminal devices to achieve reasonable CSI measurement and reporting.
