[0002] This application claims priority to Chinese Patent Application No. 202411222653.4, filed on September 2, 2024, entitled "Transmission Method, Terminal and Network Side Device with Terminal Capability or Transmission Configuration", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a transmission method for terminal capabilities or transmission configuration, a terminal, and a network-side device. Background Technology

[0004] In the future, the antennas of mobile phones, laptops or other terminals may be further increased to improve communication performance. For example, the antenna of mobile phones may be increased from 4Rx to 6Rx or 8Rx or more, and the antenna deployment of foldable screens may also be further extended to the secondary screen. In addition, the form of terminals will also be further enriched, including foldable screen devices, retractable antenna devices, rollable screen antenna devices, flexible screen devices, etc. The aggregation of multiple terminals will also face the aggregation of communication devices with more forms and larger antenna numbers.

[0005] Based on the different forms of the terminal, such as the dual-screen foldable phone, the antenna configuration and communication capabilities of the terminal will change in different forms such as the two screens being closed, opened at 90 degrees, and opened at 180 degrees. This can easily cause a mismatch between the terminal's capabilities and transmission configuration. Therefore, it is necessary to consider the reporting of terminal capabilities or transmission configuration based on the terminal form. However, there is currently no relevant feasible solution.

[0049] The following description, in conjunction with the accompanying drawings, details the terminal capabilities or transmission methods for sending configurations provided in the embodiments of this application through some examples and application scenarios.

[0050] As shown in Figure 2, this application embodiment provides a method 200 for transmitting terminal capabilities or transmission configurations. This method can be executed by the terminal; in other words, it can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0051] S202: The terminal sends first information to the network-side device, the first information indicating the terminal's capabilities; or, the terminal sends second information to the network-side device, the second information indicating the uplink signal transmission configuration. The uplink signal may include, for example, a Sounding Reference Signal (SRS) or a Demodulation Reference Signal (DMRS).

[0052] In this embodiment, the terminal can send first information to the network-side device; it can also send second information to the network-side device; and it can also send both first and second information to the network-side device.

[0053] In one embodiment, the first information or the second information is used by the network-side device to determine the configuration information or scheduling information of the terminal's uplink transmission (such as uplink data transmission). For example, the network-side device sends configuration information or scheduling information to the terminal based on the first information or the second information, so that the terminal's terminal capabilities and transmission configuration are matched.

[0054] The first information can be used to indicate the terminal capabilities of the terminal in a certain terminal form (e.g., the current terminal form) or multiple terminal forms, or to indicate the terminal capabilities of the terminal in all possible terminal forms.

[0055] In one embodiment, the terminal capabilities include at least one of the following:

[0056] 1) Terminal type.

[0057] Examples include devices such as mobile phones, smart glasses, watches, wearable devices, laptops, cars, and aircraft, or corresponding specifications such as form factor.

[0058] 2) Number of available antennas.

[0059] For example, the terminal's antenna can be divided into K parts, where each part has N1, N2, ..., N antennas. K The number of available antennas in a terminal under a certain terminal form factor may be a subset of the antenna count N. k (1≤k≤K), or the sum of the number of antennas in several parts (e.g., the sum of the number of antennas in the first and second parts, N1+N2).

[0060] Optionally, an indicator can be predefined for each part of the terminal. The terminal indirectly reports the number of available antennas by reporting the indicator of one or more parts.

[0061] The term "part" of terminal / antenna mentioned in various embodiments of this application may refer to one or more screens / panels / shells or their corresponding antennas in a multi-screen foldable screen (e.g., dual-screen foldable phone, triple-screen foldable phone, laptop) device, or one or more basic screens / panel modules / shells or their corresponding antennas in a rollable screen or flexible screen, or one or more terminals (e.g., anchor UE or assistant UE) or their corresponding antennas in a terminal aggregation scenario.

[0062] For example, there are a total of Q terminal types, where the number of available antennas for each terminal type is M1, M2, ..., M. Q When the terminal is in the q-th terminal form, the number of available antennas is M. q (1≤q≤Q).

[0063] It is understood that the number of antennas used for transmitting and receiving may be different, and the number of available antennas may refer to the number of transmitting antennas and / or the number of receiving antennas.

[0064] For example, the number of available antennas can be represented as xTyR, where x and y are positive integers, representing the number of transmitting antennas and the number of receiving antennas, respectively. For example, it can be 1T4R, 2T4R, 3T6R, 4T8R or other configurations.

[0065] 3) Number of ports.

[0066] The number of ports can refer to the number of sending ports and / or the number of receiving ports.

[0067] 4) Number of supported Multiple-Input Multiple-Output (MIMO) layers.

[0068] 5) Polarization mode.

[0069] The polarization method includes single-polarized antennas and dual-polarized antennas. The specific polarization method can be the overall polarization method of the terminal under the current terminal form, or it can be the polarization method of each part of the terminal, such as linear polarization (horizontal polarization, vertical polarization), elliptical polarization, and circular polarization.

[0070] It can be understood that the polarization mode can refer to the polarization mode corresponding to the transmitting antenna and / or the polarization mode corresponding to the receiving antenna.

[0071] 6) Antenna structure, wherein the antenna structure includes at least one of antenna layout and antenna spacing.

[0072] The antenna structure can be a two-dimensional planar antenna layout or a three-dimensional antenna layout; it can be understood that the antenna structure can refer to a transmitting antenna structure and / or a receiving antenna structure.

[0073] The antenna layout can be the overall antenna layout of the terminal in the current terminal form, or it can be the antenna layout of each part of the terminal (e.g., the antenna layout on each screen in a multi-screen foldable device); the antenna layout can be an antenna layout on a two-dimensional plane, or it can be a three-dimensional antenna layout in three-dimensional space.

[0074] The antenna spacing can be the spacing between any two antenna elements in the current terminal configuration, or it can be the antenna spacing within each part of the terminal.

[0075] By reporting the antenna structure, the terminal can improve the performance of the integrated sensing and communication system. For example, when measuring the angle of a sensing target, it is necessary to know the antenna layout of the sensing signal transmitting device and / or sensing signal receiving device.

[0076] As shown in Figure 3, Figure 3 is a schematic diagram of the antenna structure of a foldable screen device in a partially opened state when the antennas are deployed in different positions (the antennas are represented by squares); among them, Figure 3a is the antenna layout in the current terminal form, which is still a two-dimensional plane; Figure 3b is the antenna layout in the current terminal form, which is a three-dimensional space.

[0077] 7) Terminal form, wherein the terminal form includes at least one of the following: the positional relationship of the associated moving parts of the terminal, the distance between the associated moving parts of the terminal, and the terminal posture.

[0078] The associated moving parts in various embodiments of this application may be, for example, two relatively movable housings of a folding screen; two housings of a rollable screen; a terminal housing and a telescopic camera; folding wings and the main body of an aircraft, etc.

[0079] The positional relationship of the associated moving parts of the terminal, such as the angle between every two adjacent screens of a multi-screen folding device (e.g., the opening angle θ of a dual-screen folding terminal is 0 degrees, 90 degrees, 180 degrees or other angles, as shown in Figure 4), or the topological relationship or spatial positional relationship of several terminals in a terminal aggregation scenario (e.g., anchor UE or assistant UE), or the relevant parameters of a rollable screen or flexible screen indicating the degree of roll or the bending ratio (as shown in Figure 5).

[0080] Figure 4 shows the morphology of two adjacent screens of a foldable screen device at different opening angles θ; Figure 5 shows the morphology of a flexible screen device at different degrees of curling / bending ratios. Terminal hardware parameters such as the included angle (90 degrees, 180 degrees) need to be obtained in some way and transmitted to the UE modem.

[0081] In the various embodiments of this application, the terminal is not limited to a dual-screen folding screen, but can also be a triple-screen folding screen or even more screens; or it can be extended to a rollable screen device, where each planar screen unit of the rollable screen device can be a single screen.

[0082] The distance between associated moving parts of a terminal, such as the distance between antennas in a retractable antenna device when it is extended and retracted, or the distance between two terminals in a terminal aggregation scenario.

[0083] Terminal posture, such as the three-dimensional posture information of the terminal or its parts obtained based on sensor information or perception information (e.g., gyroscope information), or the orientation of the antenna panel (e.g., the azimuth, pitch, and roll angles of the device, or the rotation angle information relative to a specific direction, see Figure 6), or the holding / placement method (e.g., landscape or portrait). Figure 6 is a schematic diagram of terminal posture / panel orientation parameters.

[0084] For the information acquired by the three-dimensional gyroscope, the orientation information represents the rotation angle of the device's main axis in the horizontal plane, the pitch information represents the rotation angle of the device's main axis in the vertical plane, and the roll information represents the rotation angle of the device centered on the device's main axis.

[0085] 8) Antenna configuration, which includes at least one of the following: the positional relationship of the antenna's associated moving parts, the distance between the antenna's associated moving parts, and the antenna's attitude. For details, please refer to the description of the terminal configuration.

[0086] Reporting terminal / antenna configurations can improve the performance of integrated sensing. For example, measuring the angle of a target requires knowing the antenna layout of the sensing signal transmitting and / or receiving devices, which can be obtained through terminal / antenna configuration information. For instance, based on the opening angle θ of a folding screen and the antenna layout on each screen, the antenna layout at any opening angle θ can be calculated, and then used to calculate and measure the angle of the target.

[0087] 9) The enabled or working status of the associated moving parts of the terminal.

[0088] For example, the first associated motion component is enabled in the third terminal form, and the second associated motion component is enabled in the fourth terminal form. The second associated motion component and the first associated motion component may have overlap.

[0089] For example, it refers to the on / off state of the main screen and / or secondary screen of a dual-screen foldable terminal device. When the two screens are closed or the angle between the two screens is less than a certain threshold angle, only the front screen of the main screen is enabled; when the two screens are open or the angle between the two screens is greater than a certain threshold angle, the back screen of the main screen and the secondary screen are enabled, or the front screen of the main screen, the back screen and the secondary screen are enabled.

[0090] The terminal can implicitly indicate its form factor and / or antenna configuration information by reporting the activation or working status of associated moving parts.

[0091] 10) Number of terminals, antenna panels, or antenna subarrays.

[0092] The number of terminals can be the number of multiple terminals aggregated in a terminal aggregation scenario; the number of antenna panels can be the number of antenna panels corresponding to each terminal form in multiple terminal forms; the number of antenna subarray divisions can be the number of multiple antenna subarrays divided from an antenna array.

[0093] For example, if a terminal has a total of Q terminal forms, then in the q-th form, the number of antenna panels is S. q (1≤q≤Q).

[0094] For example, in a certain terminal form factor (such as a foldable screen terminal, when the foldable screen is fully unfolded), the terminal's antenna array can be divided into more antenna subarrays, and data transmission and reception can be performed based on the antenna subarrays.

[0095] 11) The magnitude of coupling effect or interference between antennas of multiple terminals or related moving parts.

[0096] The number of terminals in this multi-terminal system can be two or more.

[0097] For example, in a terminal aggregation scenario, when UE1 and UE2 are aggregated, the transmission of UE2 will cause some interference to the transmission of UE1, which is defined as the first interference value; when UE1 and UE3 are aggregated, the transmission of UE3 will also cause some interference to the transmission of UE1, which is defined as the second interference value; the terminal can report the interference magnitude (e.g., the first interference value and the second interference value) between each moving component (e.g., anchor UE and assistant UE) during terminal aggregation.

[0098] 12) The antenna aperture or near-field identification information of the terminal.

[0099] For example, for dual-screen foldable devices, the antenna aperture on the terminal side may change depending on the angle θ between the screens in different configurations. When the network-side device is a large-scale antenna array, this will affect the Rayleigh distance of communication and further determine whether the terminal is in the near-field or far-field region.

[0100] As shown in Figure 7, at the antenna deployment position in Figure 7, the relationship between the antenna aperture D and the angle θ between the antenna aperture and the screen of the foldable screen device is as follows: The definitions of x and y are shown in Figure 7; where y is the antenna aperture when θ = 0°, and y is the antenna aperture when θ = 90°. When θ = 180°, the antenna aperture is

[0101] Furthermore, assume the antenna aperture of the network-side device is D. net When both the network side and the terminal are antenna arrays, the Rayleigh distance / Fraunhofer distance / near-field distance used to assess whether the terminal is in the far field or near field can be expressed as: r = 2(D net +D) 2 / λ, where λ represents the wavelength.

[0102] The near-field identification information includes, for example, an indicator of whether the terminal is within the near-field range. This identifier can be a 1-bit information bit, where 0 represents the far field and 1 represents the near field; or 0 represents the near field and 1 represents the far field.

[0103] Reporting the aforementioned antenna structure or terminal / antenna configuration can improve the performance of integrated sensing. For example, when measuring the angle of a sensing target, it is necessary to know the antenna layout of the sensing signal transmitting device and / or sensing signal receiving device. For instance, in a MIMO sensing scenario where A transmits and B receives, when the terminal transmits a sensing signal, which is reflected by the sensing target and received by the base station, the antenna layout on the terminal side (linear / area array, aperture size, antenna layout, antenna spacing, etc.) will affect the measurement of the transmission angle. That is, the base station can only obtain the transmission angle of the sensing signal after knowing the aforementioned antenna parameters, and then combine this with the reception angle to determine the location information of the sensing target.

[0104] The reporting of the antenna aperture can also help determine whether the terminal is in the near field or the far field. For example, if Rayleigh distance is used to determine whether the terminal is in the near field, when both the transmitting and receiving sides are antenna arrays, the Rayleigh distance that marks the boundary between the near and far fields is defined as: 2*(base station antenna aperture + terminal antenna aperture)^2 / wavelength. The base station needs to know the antenna aperture on the terminal side when assessing whether the terminal is in the far field or the near field, which may affect the selection of the far field / near field codebook.

[0105] In one embodiment, the terminal sending first information to the network-side device includes at least one of the following:

[0106] 1) The terminal sends UE Assistance Information (UAI) to the network-side device, wherein the UAI includes the first information.

[0107] 2) The terminal sends terminal capability information to the network-side device, the terminal capability information including the first information.

[0108] 3) The terminal sends message 3 (Msg3) or message A (MsgA) in the Contention Free Random Access (CFRA) to the network-side device, wherein Msg3 or MsgA includes the first information.

[0109] In this embodiment, the terminal can report the first information via uplink Radio Resource Control (RRC) signaling, such as via UAI or via terminal capability information. The terminal can also report some or all of the information in the first information via Msg3 or MsgA in CFRA.

[0110] This application embodiment can be applied to terminals with variable forms. The terminal can dynamically report terminal capability information based on the current terminal form and update the transmission configuration under the current form. The transmission configuration may include the configuration information or scheduling information mentioned above.

[0111] In one embodiment, the second information includes at least one of the following:

[0112] 1) Resource configuration of the uplink signal, such as SRS-ResourceSet configuration.

[0113] 2) Activation information of the resources or resource sets of the uplink signal.

[0114] 3) Deactivation information of the resources or resource sets of the uplink signal.

[0115] 4) The transmission layer number or rank value of the uplink signal; for example, the maximum number of uplink layers.

[0116] 5) The transmission power of the uplink signal.

[0117] 6) The receiving mode of the terminal, for example, supports coherent reception or non-coherent reception.

[0118] In one embodiment, the terminal sending the second information includes: the terminal sending Uplink Control Information (UCI) or Media Access Control Control Element (MAC CE), wherein the UCI or MAC CE includes the second information.

[0119] In this embodiment, the terminal can trigger the transmission of uplink signals according to the terminal form, such as (ap)SRS transmission; it can also report the uplink signal transmission configuration, and the network-side device can send the subsequent uplink transmission configuration information or scheduling information to the terminal according to the uplink signal transmission configuration; or, the network-side device can directly measure the uplink signal, and determine the uplink transmission configuration information or scheduling information based on the uplink signal measurement results and send it to the terminal.

[0120] The terminal capability or transmission configuration transmission method provided in this application embodiment allows the terminal to send first information, which indicates the terminal's capabilities; the terminal can also send second information, which indicates the uplink signal transmission configuration. Through the first or second information, the network-side device can promptly know the terminal's current capabilities or transmission configuration, thereby enabling reasonable and matching transmission configurations and avoiding situations where the transmission configuration does not match the terminal capabilities (e.g., the UE's maximum MIMO layer number is 1, but the network schedules 2-layer), thus improving communication performance.

[0121] The following will first provide a detailed description of the embodiments related to the first information.

[0122] In one embodiment, before the terminal sends the first information to the network-side device, the method further includes: the terminal sending first indication information to the network-side device, the first indication information indicating at least one of the following: whether the terminal has multiple terminal forms, whether there are other terminal capabilities, whether the terminal form or terminal capability has changed, and whether the terminal supports reporting other terminal capabilities. The terminal form may be the same as or different from the terminal form described in section 7) of the above-mentioned terminal capabilities.

[0123] For example, the terminal can inform the network-side device through the first indication information that the terminal has multiple terminal forms or multiple terminal capabilities, so that the network-side device can enable the reporting of the first information or enable dynamic terminal capability reporting, so that when the terminal form or capability changes, the updated terminal capability information can be obtained as soon as possible.

[0124] In one embodiment, the first information includes at least one of the following: an identifier or index corresponding to the terminal capability of the terminal, an identifier or index corresponding to the terminal form of the terminal, wherein there is a correspondence between the terminal form and the terminal capability.

[0125] The association between the aforementioned identifier or index and the terminal form; or, the association between the aforementioned identifier or index and the terminal capabilities under the terminal form can be reported by the terminal or predefined by the protocol.

[0126] For example, the first piece of information is used to indicate the index value. For instance, the index value mode1 represents the closed state of the dual-screen foldable terminal (the angle between the two screens is 0 degrees) and / or the corresponding terminal capabilities; the index value mode2 represents the partially opened state of the dual-screen foldable terminal (the angle between the two screens is between 0 degrees and 180 degrees, such as 90 degrees) and / or the corresponding terminal capabilities; and mode3 represents the fully opened state of the dual-screen foldable terminal (the angle between the two screens is 180 degrees) and / or the corresponding terminal capabilities.

[0127] For example, the first information is bitmap information. Each bit represents a portion of the terminal's capabilities, which is the sum of the partial terminal capabilities corresponding to the bits that are 1. This can be used to represent the current terminal's capabilities. For instance, in a 2-bit bitmap, the first bit represents the terminal capability corresponding to the main screen of a dual-screen foldable terminal, the second bit represents the terminal capability corresponding to the secondary screen, the second indication information is 10 indicating that the terminal capability corresponding to the main screen is used (e.g., in the closed foldable screen state), the second indication information is 01 indicating that the terminal capability corresponding to the secondary screen is used, and the second indication information is 11 indicating that all terminal capabilities corresponding to the main and secondary screens are used (e.g., in the fully open foldable screen state).

[0128] In one embodiment, the first information is used to indicate first differential information of the terminal's capabilities. The first differential information is used to indicate the difference between the terminal's current capabilities and a baseline terminal capability (or baseline capability). The baseline terminal capability may be the terminal capability (parameter) under the terminal's basic / default / initial state, or it may be the terminal capability parameters or a previous set of terminal capability parameters under a previous terminal state. The definition of the baseline terminal capability may be predefined by the protocol.

[0129] In one embodiment, the first differential information includes at least one of the following:

[0130] 1) Baseline terminal capabilities.

[0131] For example, in a terminal aggregation scenario, the terminal capabilities of the anchor UE can be used as the baseline terminal capabilities. When the anchor UE is aggregated with UE2, the first differential information can refer to the terminal capabilities of UE2. When the anchor UE is aggregated with UE3, the first differential information can refer to the terminal capabilities of UE3.

[0132] The terminal can also indicate the baseline terminal capability through indication information. For example, the indication information is a 1-bit information bit, where 0 indicates that the baseline terminal capability is the terminal capability predefined by the protocol, and 1 indicates that the baseline terminal capability is the terminal capability of the previous terminal form / previous group / before the change.

[0133] 2) Changes in the number of available antennas.

[0134] It is understood that the amount of change in the number of antennas used for transmitting and receiving can be different, and the amount of change in the number of available antennas can refer to the amount of change in the number of transmitting antennas and / or the amount of change in the number of receiving antennas.

[0135] 3) Changes in the number of ports.

[0136] It is understood that the change in the number of ports may refer to the change in the number of transmitting ports and / or the change in the number of receiving ports.

[0137] 4) The amount of change in the number of supported MIMO layers.

[0138] 5) Information on changes in polarization mode.

[0139] The information on the change in polarization can include the transition between single-polarized antennas and dual-polarized antennas, as shown in Figure 8. The specific change in polarization refers to the change in the overall polarization of the terminal in the current form, and may also include, for example, the transition between linear polarization (horizontal polarization, vertical polarization), elliptical polarization, and circular polarization.

[0140] In Figure 8, when the folding screen changes from a fully open to a half-open state, Figure 8a shows the polarization changing from single polarization to dual polarization; Figure 8b shows the polarization remaining unchanged, still single polarization. Figure 8 considers each antenna element as single polarization, with linear polarization. The short lines in Figure 8 represent the polarization direction of the corresponding antenna element.

[0141] It can be understood that the polarization mode can refer to the polarization mode corresponding to the transmitting antenna and / or the polarization mode corresponding to the receiving antenna.

[0142] 6) Information on changes in antenna structure.

[0143] The antenna structure can be a two-dimensional planar antenna layout or a three-dimensional antenna layout, such as the relative displacement of each antenna element in three-dimensional space or the change in distance between two antenna elements; it can be understood that the antenna structure can refer to a transmitting antenna structure and / or a receiving antenna structure.

[0144] 7) Terminal form change information; the terminal form change information includes at least one of the following: the change in the positional relationship of the associated moving parts of the terminal, the change in the distance of the associated moving parts of the terminal, and the change in the terminal posture.

[0145] The changes in the positional relationship of the associated moving parts of the terminal, such as the change in the angle between every two adjacent screens of a multi-screen foldable device (e.g., the change in the opening and closing angle of a dual-screen foldable terminal is +180 degrees, indicating that the foldable screen goes from closed to fully open), or the changes in the topological or spatial relationship of several terminals (e.g., anchor UE or assistant UE) in a terminal aggregation scenario, or the changes in the degree of roll-up or bending ratio of a rollable screen or flexible screen.

[0146] The amount of distance change of associated moving parts of the terminal, for example, the distance between antennas of a retractable antenna device when it is extended and retracted, or the distance between two terminals in a terminal aggregation scenario.

[0147] The amount of change in terminal attitude, such as the amount of change in three-dimensional attitude information of the terminal or its parts obtained based on sensor information or perception information (e.g., gyroscope information) or the amount of change in antenna panel orientation (e.g., the azimuth, pitch and roll angle information of the device, or the rotation angle information relative to a specific direction), or the amount of change in holding / placement method (e.g., landscape or portrait).

[0148] 8) Antenna morphology change information; the antenna morphology change information includes at least one of the following: the change in the positional relationship of the antenna's associated moving parts, the change in the distance of the antenna's associated moving parts, and the change in the antenna's attitude.

[0149] 9) Changes in the activation or working status of the associated moving parts of the terminal.

[0150] For example, 0 indicates no change, and 1 indicates a change (from on to off, or from off to on).

[0151] 10) Changes in the number of terminals, antenna panels, or antenna subarrays.

[0152] 11) The amount of change in coupling effect or interference between antennas of multiple terminals or related moving parts.

[0153] 12) The change in the antenna aperture of the terminal or the change in near-field identification information.

[0154] 13) Has the antenna aperture or near-field identification information of the terminal changed?

[0155] Based on any one or more of the above embodiments, after sending the first information, the method further includes: the terminal receiving uplink transmission configuration information or scheduling information; wherein the configuration information includes at least one of the following:

[0156] 1) Uplink transmission parameters.

[0157] 2) Maximum number of uplink transmission layers.

[0158] 3) Uplink precoding information.

[0159] 4) Uplink transmission codebook.

[0160] 5) Number of uplink transmission ports.

[0161] 6) Uplink reference signal configuration, such as SRS-ResourceSet configuration parameters.

[0162] 7) Downlink transmission parameters.

[0163] 8) Maximum number of downlink transmission layers.

[0164] 9) Downlink precoding information.

[0165] 10) Downlink transmission codebook.

[0166] 11) Number of downlink transmission ports.

[0167] 12) Downlink reference signal configuration.

[0168] In this embodiment, after receiving the first information, the network-side device can resend the uplink transmission configuration information or scheduling information based on the first information.

[0169] Based on any one or more of the above embodiments, before sending the first information, the method further includes at least one of the following:

[0170] 1) Receive third information, the third information being used to indicate permission for the terminal to send the first information;

[0171] In this embodiment, the network-side device can send third information to the terminal. This third information is an enable message for the terminal to send the first information, that is, it is used to indicate that the terminal is allowed to send the first information. When the network-side device allows the terminal to send the first information, the terminal can send the first information as needed, for example, when the terminal form changes, the first information is sent to update the terminal capabilities.

[0172] 2) Receive fourth information, which is used to instruct or request the terminal to send the first information.

[0173] In this embodiment, the network-side device can send a fourth message to the terminal, which is used to instruct the terminal to send the first message.

[0174] There is a difference between the third and fourth information mentioned above. If it is "allow to send", it means that after receiving the third information, the terminal can report the first information when needed (the terminal can decide when to report); if it is "instruction / request to send", it means that after receiving the fourth information, the terminal will immediately report the first information (the network decides when to report).

[0175] The following will describe an embodiment related to the second information.

[0176] The terminal can trigger the transmission of uplink signals based on its terminal configuration, such as (ap)SRS transmission. It can also report the uplink signal transmission configuration. The network-side device sends uplink transmission configuration information or scheduling information to the terminal based on the uplink signal transmission configuration. Alternatively, the network-side device can directly measure the uplink signal and determine the uplink transmission configuration information or scheduling information based on the measurement results and send it to the terminal.

[0177] In one embodiment, the resource configuration of the uplink signal includes at least one of the following:

[0178] 1) The number of resource sets of the uplink signal, such as the number of SRS resource sets.

[0179] 2) The number of uplink signal resources in each uplink signal resource set, for example, how many SRS resources are contained in each SRS resource set.

[0180] 3) The uplink signal resource set includes uplink signal resources, such as which SRS resources are included in each SRS resource set; further, it may also include the location of the uplink signal resources, such as the time domain resource location / length and / or frequency domain resource location / range of the uplink signal resources.

[0181] 4) The number of ports, port locations, or mapping relationship between ports and resources of the uplink signal resources.

[0182] For example, during SRS antenna switching, a terminal is configured with two SRS resource sets, and each SRS resource set is configured with two SRS resources transmitted on different OFDM symbols; each SRS resource corresponds to two SRS ports, and the terminal antenna ports associated with the two SRS ports of the second SRS resource in each SRS resource set are different from the terminal antenna ports associated with the two SRS ports of the first SRS resource in the same SRS resource set.

[0183] In one embodiment, after the terminal sends the second information to the network-side device, the method further includes: sending the uplink signal after a first time interval following the sending of the second information.

[0184] The first time interval can be the time interval between the first time symbol occupied by the uplink signal and the last time symbol occupied by the second information transmission; the first time interval can also be expressed as a time offset.

[0185] The uplink signal can be sent based on the transmission configuration indicated by the second information. For example, the terminal sends the uplink signal using the resource configuration / layer number / power in the second information.

[0186] In one embodiment, after the terminal sends the second information to the network-side device, the method further includes: receiving the fifth information sent by the network-side device; and sending the uplink signal based on the fifth information.

[0187] In this embodiment, the terminal can send uplink signals using the resource configuration / layer number / power in the fifth information sent by the network-side device.

[0188] For example, the fifth information may be information carried by the Physical Downlink Control Channel (PDCCH). The terminal listens to the PDCCH sent by the network-side device. The PDCCH is used to respond to the transmission configuration reported by the terminal in the second information (e.g., SR or PUCCH), indicating whether the network-side device has received the second information (ACK), or indicating whether the terminal uses the transmission configuration reported in the second information to transmit uplink signals.

[0189] The fifth piece of information can be sent from the network side to the terminal after receiving the second information.

[0190] The fifth information is used to indicate at least one of the following: the resource configuration of the uplink signal, the activation or deactivation information of the uplink signal, the transmission layer number or rank value of the uplink signal, the transmission power of the uplink signal, the second time interval, whether the second information (e.g., ACK) is received, and whether the transmission configuration reported in the second information is adopted; wherein, the second time interval is: the time interval between the first time symbol occupied by the uplink signal and the last time symbol occupied by the reception of the fifth information; the second time interval can also be expressed as a time offset.

[0191] In one embodiment, after the terminal sends the uplink signal, the method further includes: receiving sixth information sent by a network-side device, the sixth information being used to indicate configuration information or scheduling information for the uplink transmission.

[0192] In this embodiment, after the terminal sends an uplink signal, it receives a sixth message sent by the network-side device. The sixth message is used to schedule uplink data transmission (e.g., PUSCH) and perform corresponding resource configuration.

[0193] The sixth piece of information includes, for example, Downlink Control Information (DCI), which may include at least one of the following: a Sounding Reference Signal Resource Indicator (SRI) and a Transmitted Precoding Matrix Indicator (TPMI).

[0194] The SRI is used to indicate the transmission mode (CodeBook or nonCodeBook) or associated transmission resources of the uplink transmission, and may be associated with second or fifth information (e.g., resource configuration, or activation / deactivation information of resources / resource sets).

[0195] The TPMI is used to indicate the precoding information of the uplink transmission. The TPMI field size can be associated with the second or fifth information (e.g., the maximum number of transmission layers / rank value); that is, the TPMI field only includes precoding information or codebook information with a transmission layer number not greater than the maximum number of transmission layers / rank value.

[0196] To explain in detail the terminal capabilities or transmission methods for sending configurations provided in the embodiments of this application, the following will describe them in conjunction with several specific embodiments.

[0197] Example 1: The terminal dynamically updates its capabilities through terminal capability reporting, UAI reporting, or CFRA, including the following examples.

[0198] Example 1-1

[0199] The UE reports terminal capability information, including terminal capabilities and corresponding indexes for all terminal forms. When the terminal form changes, the UE reports the identifier or index corresponding to the current terminal capability, informing the network-side device of the corresponding terminal capability, as shown in Figure 9, including the following steps:

[0200] Step 1: The UE receives the third information, indicating that the network-side device instructs the UE to report the first information.

[0201] Step 2: According to the instructions of the network-side equipment, the UE sends the first information. The first information includes the terminal capabilities corresponding to all UE forms and their corresponding indexes. The terminal capabilities include information such as the corresponding antenna structure, number of ports, polarization mode, maximum number of MIMO layers, etc.

[0202] Step 3: The UE receives the fourth information, indicating that the network-side device allows the UE to dynamically report the first information.

[0203] Step 4: When the terminal form changes, the UE sends the first information, which is the index corresponding to the current terminal capability.

[0204] After the UE sends the first information, the network-side device may respond with an RRC reconfiguration message to send a new configuration to the UE.

[0205] Examples 1-2

[0206] The UE sends terminal capability information, which only includes the terminal capabilities under the current terminal form (the network enables dynamic terminal capability reporting). Then, when the terminal form changes, it dynamically reports the changed terminal capabilities, as shown in Figure 10, including the following steps:

[0207] Step 1: The UE receives the third information, indicating that the network-side device instructs the UE to report the first information.

[0208] Step 2: According to the instructions of the network-side device, the UE sends the first information, which includes the terminal capabilities corresponding to the current terminal form of the UE, such as the corresponding antenna structure, number of ports, polarization mode, maximum number of MIMO layers, etc.

[0209] Step 3: The UE receives the fourth information, indicating that the network-side device allows the UE to dynamically report the first information.

[0210] Step 4: When the terminal form changes, the UE sends the first information to report the changed terminal capabilities, such as antenna structure, number of ports, polarization mode, maximum number of MIMO layers, etc.

[0211] Before step 4, the terminal may also send a first indication message to the network-side device; the first indication message is used to indicate at least one of the following: whether the terminal has multiple terminal forms, whether there are other terminal capabilities, whether the terminal supports reporting other terminal capabilities, and whether the terminal form or terminal capability has changed. Specifically, the UE may send the first information and the first indication message in step 2; or the UE may send the first indication message after step 2 and before step 4.

[0212] After the UE sends the first information, the network-side device may respond with an RRC reconfiguration message to send a new configuration to the UE.

[0213] Examples 1-3

[0214] The UE sends terminal capability information, which only includes the terminal capabilities under the current terminal form (the network enables dynamic terminal capability reporting). Then, when the terminal form changes, it dynamically reports the changed first differential information, as shown in Figure 11, including the following steps:

[0215] Step 1: The UE receives the third information, indicating that the network-side device instructs the UE to report the first information.

[0216] Step 2: As instructed by the network-side device, the UE sends the first information, which includes the terminal capabilities corresponding to the UE's current terminal form factor, such as the corresponding antenna structure, number of ports, polarization mode, maximum number of MIMO layers, etc. Step 3: The UE receives the fourth information, indicating that the network-side device allows the UE to dynamically report the first information.

[0217] Step 4: When the terminal form changes, the UE sends the first information (first differential information) to report the changes in the terminal's capabilities, such as changes in antenna structure, number of ports, polarization mode, and maximum number of MIMO layers.

[0218] Before step 4, the terminal may also send a first indication message to the network-side device; the first indication message is used to indicate at least one of the following: whether the terminal has multiple terminal forms, whether there are other terminal capabilities, whether the terminal supports reporting other terminal capabilities, and whether the terminal form or terminal capability has changed. Specifically, the UE may send the first information and the first indication message in step 2; or the UE may send the first indication message after step 2 and before step 4.

[0219] After the UE sends the first information, the network-side device may respond with an RRC reconfiguration message to send a new configuration to the UE.

[0220] Examples 1-4

[0221] The UE dynamically updates its terminal capabilities based on a four-step CFRA procedure. The UE sends a PRACH (first indication information, such as a specific preamble) to inform the network that the UE's capabilities have changed. The network-side device sends Msg2 to instruct the UE to report the updated terminal capabilities. The UE sends Msg3 (first information) to report the updated terminal capabilities, as shown in Figure 12. The procedure includes the following steps:

[0222] Step 1: The UE receives RACH preamble information indicated by the network-side device. The preamble information is used for terminal capability reporting.

[0223] Step 2: When the UE configuration changes, the UE sends Msg1 (i.e., the first indication information) based on the CFRA procedure, such as sending a special preamble, to inform the network terminal that its capabilities have changed.

[0224] Step 3: The UE receives Msg2, which is the third information mentioned above, indicating that the network instructs the UE to report the first information.

[0225] Step 4: The UE sends Msg3 to report the first information, which includes the terminal capabilities or first differential information corresponding to the current terminal form of the UE, such as the corresponding antenna structure, number of ports, polarization mode, maximum number of MIMO layers, etc.

[0226] Step 5: The UE receives Msg4 for RRC reconfiguration.

[0227] Examples 1-5

[0228] The UE dynamically updates its terminal capabilities based on a two-step CFRA procedure. The UE sends MsgA (first indication information and first information; the first indication information is, for example, a specific preamble in MsgA) to inform the network that the terminal capabilities have changed and the updated terminal capabilities. The network-side equipment sends MsgB to perform RRC reconfiguration, as shown in Figure 13, including the following steps:

[0229] Step 1: The UE receives RACH preamble information indicated by the network-side device. The preamble information is used for terminal capability reporting.

[0230] Step 2: When the UE form changes, the UE sends MsgA (first indication information + first information) based on the CFRA procedure, such as sending a special preamble + updated terminal capabilities to inform the network of the changed terminal capabilities.

[0231] Step 3: The UE receives MsgB for RRC reconfiguration.

[0232] Example 2: The terminal triggers SRS transmission based on the change in shape.

[0233] Example 2-1

[0234] The UE sends the second information and then sends an uplink signal after the first time interval, as shown in Figure 14, including the following steps:

[0235] Step 1: When the UE's form changes, the UE sends a second message to inform the network-side device of the uplink signal transmission configuration.

[0236] Step 2: After the UE completes the first time interval of sending the second information, the UE sends an uplink signal, such as one or more sets of SRS.

[0237] Step 3: The UE receives the sixth piece of information, namely the scheduling information from the network-side equipment.

[0238] Example 2-2

[0239] The UE sends the second information, receives the fifth information sent by the network-side device, and sends an uplink signal based on the fifth information, as shown in Figure 15, including the following steps:
