The waveform needs to support the requirements of these features. This scenario requires the peak average power ratio (Peak Average Power Ratio, PAPR) of the signal waveform to be as low as possible. The lower the PAPR of the signal waveform, the higher the power amplifier (Power Amplifier, PA) efficiency, and thus the lower the power consumption and cost. Therefore, in order to meet the application scenarios of lower PAPR requirements of 5G signals, it is urgent for those skilled in the art to implement a transmission method that makes the PAPR lower.

It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0043] The following is a brief introduction to the principles of Frequency Domain Spectrum Shaping (FDSS):

[0044] After a set of discrete-time signals passes through a DAC module, the peak-to-average power ratio (PAPR) of the output analog signal is related to the correlation between the discrete-time signals. Suppose a set of discrete-time data signals y(n) is convolved with a set of discrete-time data d(n) in the time domain to obtain yd(n):

[0045]

[0046] Let PAPR1 and PAPR2 be the peak-to-average power ratios of the output signals of y(n) and yd(n) after passing through the DAC. If d(n) is a set of designed weight coefficients, the correlation between adjacent data of yd(n) will be better than that between adjacent data of y(n). Therefore, PAPR2 will be less than PAPR1. Convolving a set of discrete time-domain data with a set of designed discrete data can effectively reduce PAPR.

[0047] According to the convolution theorem, the convolution operation of two time-domain signals is equivalent to the dot product operation of those two time-domain signals in the frequency domain. Therefore, transforming a set of discrete time-domain data signals into discrete frequency-domain data signals after DFT, then dotting them with a pre-designed spectrum-shaping sequence, and finally performing IDFT on the resulting time-domain signal can effectively reduce PAPR. Since the dot product operation is less complex than the convolution operation, this PAPR reduction technique operates better in the frequency domain, hence it is called Spectrum Shaping FDSS.

[0048] Furthermore, during FDSS transmission, a few adjacent Physical Resource Blocks (PRBs) can be reserved to adjust the frequency domain waveform roll-off, resulting in a smoother, more shaped waveform, optimizing the d(n) coefficient, and achieving a better low PAPR effect. This can be achieved primarily through two methods: reserving idle PRBs and reserving duplicate PRBs.

[0049] Figure 2 The image shown is a reserved idle PRB. Figure 3 The image shown is a reserved duplicate PRB. Figure 3 For example, the repetitive information in the extended PRB on the left is the information of the fifth PRB in the frequency domain signal, while the repetitive information in the extended PRB on the right is the information of the first PRB in the frequency domain signal.

[0050] Due to the presence of redundant RBs, the spectral shaping waveform can achieve a smoother drop at the roll-off, reducing sharper jitter. As is well known, the roll-off of the waveform determines the implementation difficulty of the device. Reserving PRBs reduces the power at the peak and moderates the roll-off, resulting in a significant performance improvement and practical value.

[0051] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0052] Figure 4 This is one of the flowcharts illustrating the transmission method provided in the embodiments of this application. For example... Figure 4 As shown, the transmission method provided in this embodiment includes:

[0053] Step 101: The terminal acquires the target frequency domain resources;

[0054] The target frequency domain resource is the frequency domain resource used by the terminal for uplink transmission. The terminal can obtain this target frequency domain resource based on the network device's configuration, default configuration, or predefined rules. The frequency domain resource may include subcarriers or physical resource blocks (PRBs).

[0055] Step 102: The terminal performs FDSS (Frequency Direct Structuring) processing on the transmission channel or signal based on the target frequency domain resources, and then performs uplink transmission on the processed transmission channel or signal.

[0056] Specifically, the terminal uses the target frequency domain resources to map the transmission channel or signal, that is, to map the time domain signal into the frequency domain signal, and then performs FDSS processing. FDSS processing can be regarded as multiplying the frequency domain signal by a frequency domain raised cosine filter, including but not limited to a raised cosine roll-off filter, and then uplinking the processed transmission channel or signal.

[0057] FDSS includes the following types:

[0058] The first type is the FDSS without extensions;

[0059] The second type, such as Figure 2 As shown, the extended FDSS reserves idle resources;

[0060] The third type, such as Figure 3 As shown, the extended FDSS reserves duplicate resources;

[0061] For the second type of FDSS, in addition to the frequency domain resources used for transmission channels or signals, extra frequency domain resources can be scheduled. These resources, on which no other information is transmitted, act as a guard band. In this method, the terminal can place the out-of-band roll-off generated by the shaping process into the reserved frequency domain resources to achieve waveform smoothing.

[0062] For the third type of FDSS, in addition to the frequency domain resources used for transmission channels or signals, extra frequency domain resources can be scheduled. These resources contain the same repetitive information as the main lobe of the signal after FDSS processing, acting as a guard band. In this approach, the terminal can place the out-of-band roll-off generated by the shaping process into the frequency domain resources with repetitive information, achieving waveform smoothing. Filling the reserved frequency domain resources with repetitive information ensures the orthogonality between subcarriers and reduces inter-carrier interference.

[0063] In this embodiment, the terminal acquires target frequency domain resources; the terminal performs FDSS (Frequency Direct Structuring) processing on the transmission channel or signal based on the target frequency domain resources, and then performs uplink transmission on the processed transmission channel or signal. Since the data has undergone FDSS processing, the correlation between adjacent data in the data after FDSS processing is better than the correlation before FDSS processing, thus reducing PAPR (Parallel Per Parameter).

[0064] In one embodiment, step 101 can be implemented as follows:

[0065] The terminal acquires target frequency domain resources based on the first indication information. The first indication information is sent by the network device and includes at least one of the following: FDSS enable information, FDSS type information, and target frequency domain resource information.

[0066] The first instruction information is sent in at least one of the following ways:

[0067] The first message signaling carries the first instruction information; or,

[0068] The configuration information of the first channel carries first indication information and indicates the configuration information of the first channel of the terminal through second indication information; or, the configuration information of the first channel carries first indication information and indicates the configuration information of the first channel through the MAC control unit CE.

[0069] Specifically, such as Figure 5 As shown, in step 100, the network device sends a first indication information to the terminal. The first indication information can be used to instruct the FDSS to process and perform uplink transmission of resource configuration information. Based on the first indication information, the terminal obtains the target frequency domain resources. The first indication information includes at least one of the following: FDSS enable information, FDSS type information, and target frequency domain resource information.

[0070] The first instruction information is sent in at least one of the following ways:

[0071] One approach: The first message signaling carries the first instruction information;

[0072] The first message signaling may be, for example, higher-level signaling such as Radio Resource Control (RRC) signaling. In other embodiments, it may also be sent via other signaling methods; this application does not limit this approach.

[0073] Another approach: The configuration information of the first channel carries the first indication information, and the second indication information indicates the configuration information of the first channel of the terminal;

[0074] The first channel is, for example, the Physical Uplink Control Channel (PUCCH) or the Physical Sidelink Control Channel (PSCCH).

[0075] In addition to carrying at least one of the following: FDSS enable information, FDSS type information, and target frequency domain resource information, the configuration information of the first channel may also carry: index information of the configuration information of the first channel. The network device can indicate the index information of the configuration information of the first channel to the terminal through the second indication information.

[0076] The second indication information indicates the index information of the configuration information of the first channel of the terminal. The second indication information is carried, for example, through downlink control information (DCI), such as through the original indication field or the newly added indication field of DCI, or implicit indication. Implicit indication includes, but is not limited to, implementation through semi-static configuration combined with dynamic indication of DCI. For example, the network device pre-configures or predefines the configuration information of the first channel carrying the first indication information, and indicates the configuration information with the help of the indication field in DCI.

[0077] The second indication information can also be indicated by the second message signaling. That is, the network device configures the configuration information in a semi-static way, for example, it configures periodic configuration information that can be used to carry the first indication information, and then indicates the index information of the configuration information through the second message signaling. For example, the index information of the configuration information can be indicated through the configuration information of periodic channel state information (CSI) or the configuration information of uplink scheduling request (SR).

[0078] Another approach: The configuration information of the first channel carries the first indication information, which is obtained through the activation instruction of the Media Access Control (MAC) control element (CE).

[0079] Specifically, when semi-static CSI is transmitted in PUCCH, it is activated or deactivated using SP CSI reporting on PUCCHActivation / Deactivation MAC CE. The SP CSI reporting on PUCCHActivation / Deactivation MAC CE in this MAC CE... i The domain determines how the configuration information for the first channel is indicated; i represents S. i The number of bits used for indication in the field, through the indication of the first i bits, can obtain the index information (Id) of the CSI-Report Config configured as semiPersistentOnPUCCH, while the (i+1)th bit of S i The value is used to indicate activation or deactivation. For example, S i+1 Setting it to 1 indicates that the CSI-Report Config configuration information configured as semiPersistentOnPUCCH is activated, enabling the transmission of semi-static CSI on the PUCCH.

[0080] The specific indication method is as follows: each CSI-Report Config configured as semiPersistentOnPUCCH corresponds to a reportConfigId. The smallest of these Id indices uses the S0 indicator in MAC-CE, the next smallest uses the S1 indicator, and so on. For example, if there are three configuration entries for semiPersistentOnPUCCH, then S2 corresponds to the configuration with the largest ID value. S3 then corresponds to the activation or deactivation indicator for that MAC-CE, for example, 1 for activation and 0 for deactivation. Through S... i After the Id index information is indicated, the CSI-Report Config corresponding to that Id will contain PUCCH-CSI-Resource configuration information, which includes the PUCCH resource configuration index, thereby obtaining the configuration information of the first channel.

[0081] In the above embodiments, the network device configures resource information for FDSS processing and uplink transmission for the terminal through the first indication information. Specifically, the indication can be made through direct or implicit indication, which is simple to implement and highly flexible.

[0082] In one embodiment, the terminal determines the type of FDSS based on the first indication information, and "acquiring the target frequency domain resource" can be achieved in the following way:

[0083] When the FDSS type is the first type, the terminal acquires the first frequency domain resource, which is used to map the transmission channel or signal before FDSS processing; the target frequency domain resource includes the first frequency domain resource.

[0084] When the FDSS type is type 2 or type 3, the terminal acquires the first frequency domain resource and the second frequency domain resource. The target frequency domain resource includes the first frequency domain resource and the second frequency domain resource. The first frequency domain resource is used to map the transmission channel or signal before FDSS processing, and the second frequency domain resource is a reserved resource.

[0085] Specifically, when the FDSS type is the first type, that is, in the case of FDSS without extension, the target frequency domain resources include the first frequency domain resources. The first frequency domain resources are used to map the transmission channel or signal before FDSS processing, that is, the first frequency domain resources are used to transmit the main lobe information of spectrum shaping.

[0086] When the FDSS type is type 2 or type 3, that is, when there is extended FDSS, the target frequency domain resources include first frequency domain resources and second frequency domain resources. The first frequency domain resources are used to map the transmission channel or signal before FDSS processing, and the second frequency domain resources are reserved resources. The second frequency domain resources can be used to transmit the out-of-band roll-off generated by spectrum shaping.

[0087] In the above implementation, different types of FDSS have different target frequency domain resources. Therefore, when acquiring target frequency domain resources, the type of FDSS is first determined, and then the target frequency domain resources are acquired according to the type of FDSS, which makes the implementation simple.

[0088] Optionally, such as Figure 2 As shown, when the FDSS type is type 2, the reserved resources are not used to map information in the transmission channel or signal;

[0089] Specifically, for the second type of FDSS, the reserved resources are idle resources; there is no other information transmission on these reserved resources, which act as a guard band. In this mode, the terminal can place the out-of-band roll-off generated by spectrum shaping into the reserved resources to achieve waveform smoothing.

[0090] Optionally, such as Figure 3 As shown, when the FDSS type is type 3, reserved resources are used to map some of the repetitive information in the transmission channel or signal.

[0091] Specifically, for the third type of FDSS, the reserved resources contain the same repetitive information as the main lobe of spectrum shaping, acting as a guard band. In this method, the terminal can place the out-of-band roll-off generated by spectrum shaping into the frequency domain resources with repetitive information, thereby achieving waveform smoothing.

[0092] In the above embodiments, the reserved resources can act as a guard band, and the terminal can put the out-of-band roll-off generated by spectrum shaping into the reserved frequency domain resources, thereby achieving the purpose of smoothing the waveform.

[0093] In one embodiment, "determining the type of FDSS" can be achieved in the following way:

[0094] If the first indication information includes FDSS enabling information, and the FDSS enabling information is used to indicate that FDSS is enabled, the terminal determines the type of FDSS according to the preset configuration information; or,

[0095] If the first indication information includes FDSS type information, the terminal determines the type of FDSS based on the FDSS type information.

[0096] Specifically, when the first indication information includes FDSS enabling information, and the FDSS enabling information is used to indicate that FDSS is enabled, meaning the terminal needs to perform FDSS processing before uplink transmission, the terminal first determines the type of FDSS. If the first indication information does not include the type information of that FDSS, for example, the type of FDSS is determined based on preset configuration information, and uplink transmission is performed based on the default configuration or rules corresponding to the determined FDSS type. The preset configuration information is, for example, information pre-configured by the network device, default configuration information, or predefined configuration information.

[0097] If the first indication information includes FDSS type information, and if the first indication information does not include target frequency domain resource information, uplink transmission is performed based on preset frequency domain resources, such as uplink transmission based on default configuration or rules; if the first indication information includes target frequency domain resource information, uplink transmission is performed based on target frequency domain resources, for example, the target frequency domain resources can be used to map the transmission channel or signal, and then FDSS processing is performed, and then uplink transmission is performed on the FDSS-processed transmission channel or signal.

[0098] In one embodiment, the step "the terminal acquires the target frequency domain resources" can be implemented in the following way:

[0099] If the first instruction information does not include information about the target frequency domain resources, the terminal obtains the target frequency domain resources based on the preset configuration information;

[0100] If the first instruction information includes information about the target frequency domain resources, the terminal acquires the target frequency domain resources based on the target frequency domain resources information.

[0101] Specifically, for extended FDSS, if the first indication information includes information about the target frequency domain resources, the terminal obtains the target frequency domain resources based on the information about the target frequency domain resources, that is, it obtains the first frequency domain resources and the second frequency domain resources.

[0102] If the first indication information does not include information about the target frequency domain resources, the terminal obtains the target frequency domain resources based on preset configuration information, i.e., it obtains the first frequency domain resources and the second frequency domain resources. The preset configuration information may be, for example, information pre-configured by the network device, default configuration information, or predefined configuration information.

[0103] For FDSS without extension, the method of acquiring first frequency domain resources is similar to the above scheme, and will not be repeated here.

[0104] Optionally, the method further includes:

[0105] The terminal receives third indication information sent by the network device; the third indication information is carried in the Frequency Domain Resource Assignment (FDRA) in the downlink control information (DCI), and the third indication information is used to indicate the information of the second frequency domain resources.

[0106] Specifically, the third indication information can be carried through downlink control information (DCI), for example, by directly indicating through the original indication field or newly added indication field of DCI, or by implicit indication. Implicit indication can be implemented, for example, by semi-static configuration combined with dynamic indication of DCI. For example, network devices can pre-configure or pre-define second frequency domain resources, and determine the second frequency domain resources by using the indication field in DCI, such as by using the indication field in FDRA of DCI.

[0107] Optionally, the number of PRBs included in the second frequency domain resources is less than or equal to the maximum number of PRBs N, where N can be specified by the protocol. For example, Release 15 specifies that the maximum number of PRBs for PUCCH cannot exceed 16 RBs; for example, the maximum number of PRBs for PUSCH cannot exceed the maximum value of the BWP it belongs to (the maximum number of PRBs varies depending on the subcarrier spacing).

[0108] The above embodiments provide several ways to determine the target frequency domain resources, and the frequency domain resources of the extended FDSS can be indicated directly or implicitly.

[0109] In one embodiment, step 102 can be implemented as follows:

[0110] Based on the type of FDSS, the terminal maps the transmission channel or signal using the target frequency domain resources and performs FDSS processing.

[0111] Specifically, based on the type of FDSS, the terminal maps the transmission channel or signal using the target frequency domain resources. That is, based on the type of FDSS, the time domain signal is mapped into a frequency domain signal, and then FDSS processing is performed. FDSS processing can be regarded as the frequency domain signal being multiplied by a frequency domain raised cosine filter, and the processed transmission channel or signal is then transmitted uplink.

[0112] In the above embodiments, since FDSS processing has been performed, the correlation between adjacent data in the data after FDSS processing is better than the correlation before FDSS processing, thus reducing PAPR.

[0113] In one embodiment, the transmission channel satisfies at least one of the following criteria:

[0114] The error vector magnitude (EVM) of the modulation scheme corresponding to the transmission channel is less than or equal to a first threshold, wherein the first threshold is the maximum value of the EVM of the modulation scheme corresponding to the first transmission scheme;

[0115] The maximum power reduction (MPR) of the modulation scheme corresponding to the transmission channel is less than or equal to the second threshold, where the second threshold is the maximum value of the MPR of the modulation scheme corresponding to the first transmission scheme.

[0116] The in-band energy (IBE) corresponding to the transmission channel is less than or equal to a third threshold, wherein the third threshold is greater than or equal to the maximum value of the IBE corresponding to the first transmission mode;

[0117] The out-of-band energy (OBE) corresponding to the transmission channel is less than or equal to the fourth threshold, wherein the fourth threshold is greater than or equal to the maximum value of the OBE corresponding to the first transmission mode;

[0118] The terminal's transmission power is less than or equal to the fifth threshold and greater than or equal to the sixth threshold, wherein the fifth threshold is the maximum value of the terminal's transmission power corresponding to the first transmission mode, and the sixth threshold is the minimum value of the terminal's transmission power corresponding to the first transmission mode.

[0119] The first transmission mode is a transmission mode that does not perform FDSS spectrum shaping.

[0120] The thresholds mentioned above can be specified by the protocol or pre-configured, such as the values ​​specified in the RAN4 radio frequency index.

[0121] In one embodiment, the method may further include the following steps:

[0122] The terminal receives the fourth indication information sent by the network device. The fourth indication information is used to indicate the cancellation of the target frequency domain resources. This step is not in any particular order with steps 101 and 102.

[0123] The terminal uses the following methods for uplink transmission:

[0124] One approach: The terminal stops uplink transmission.

[0125] Specifically, upon receiving an instruction from a network device to cancel a target frequency domain resource, uplink transmission using that target frequency domain resource can be stopped.

[0126] Alternatively, the target frequency domain resources are not resources that can be dynamically scheduled by network devices.

[0127] Specifically, when configuring resources for terminals, network devices should avoid using frequency domain resources intended for other purposes. For example, resources that can be dynamically scheduled by the network device should not be configured as the target frequency domain resource.

[0128] Another approach: The terminal, based on the fifth instruction information sent by the network device, performs uplink transmission of the transmission channel or signal using the first transmission method based on the target frequency domain resources.

[0129] The fifth indication information is used to indicate at least one of the following: FDSS enable information, FDSS type information, and target frequency domain resource information.

[0130] Specifically, if the terminal receives a network device instruction to cancel the target frequency domain resource, and then receives a fifth instruction message from the network device, such as FDSS enable information, which disables FDSS, the terminal can use the uplink transmission mode without FDSS processing according to the instruction of the fifth instruction message. In this case, the uplink transmission mode can use the target frequency domain resource indicated by the fifth instruction message.

[0131] Another approach: The terminal, based on the fifth instruction information sent by the network device, processes the transmission channel or signal using the first type of FDSS based on the target frequency domain resources, and then transmits the processed transmission channel or signal uplink.

[0132] Specifically, if the terminal receives a network device instruction to cancel the target frequency domain resource, and then receives a fifth instruction message from the network device, such as the fifth instruction message including FDSS type information, and the type of the type information indicates a first type of FDSS, then the terminal can process the channel or signal using the first type of FDSS according to the instruction of the fifth instruction message, that is, process the channel or signal using an unextended FDSS, and then perform uplink transmission of the processed transmission channel or signal.

[0133] In one embodiment, the fifth instruction information is sent in at least one of the following ways:

[0134] The original indication field of the downlink control information (DCI) and the added indication field in the downlink control information (DCI) carry the fifth indication information; or,

[0135] DCI implicitly indicates the fifth indication information.

[0136] Specifically, the fifth indication information can be carried through the downlink control information (DCI), for example, through the original indication field, the newly added indication field, or the implicit indication in the DCI. The implicit indication, such as semi-static configuration, can be combined with the implicit indication in the DCI to determine the fifth indication information. For example, the network device pre-configures or predefines the type of FDSS corresponding to a certain modulation method. The modulation method can be determined by the indication field in the DCI, and then the type of FDSS can be determined.

[0137] Optionally, the Time Domain Resource Assignment (TDRA) in the Downlink Control Information (DCI) carries fifth indication information; or,

[0138] Downlink control information (DCI) carries fifth indication information; or,

[0139] The modulation and coding scheme in the downlink control information (DCI) implicitly indicates the fifth indication information.

[0140] In the above embodiments, when the network device requests the cancellation of uplink transmission based on the target frequency domain resources, the current uplink transmission can be stopped, or uplink transmission can be performed based on the new instructions from the network device, which provides greater flexibility.

[0141] In other embodiments, optionally, the fourth indication information is used to indicate the cancellation of reserved resources in the target frequency domain resources, that is, the terminal can perform unextended FDSS uplink transmission, or use the first transmission mode to perform uplink transmission, that is, not perform FDSS uplink transmission.

[0142] In one embodiment, step 102 can be implemented in the following ways:

[0143] If the reserved resources are reserved resources for at least two terminals to reuse, and the sixth indication information sent by the network device is received, the terminal performs uplink transmission according to the sixth indication information; the sixth indication information is used to instruct the terminal to perform uplink transmission using the first transmission method; or, to process the transmission channel or signal using FDSS and perform uplink transmission.

[0144] When the reserved resources are reserved for at least two terminals to reuse, the terminal performs uplink transmission of the processed transmission channel or signal.

[0145] If the reserved resources are reserved for at least two terminals to reuse, the terminal stops uplink transmission.

[0146] Specifically, when the reserved resources are reserved for at least two terminals to share, the reserved resources, i.e., the second frequency domain resources, are as follows: Figure 2 , Figure 3 If there are idle resources or resources transmitting duplicate information, the terminal can use the original type of FDSS to process the channel or signal and perform uplink transmission, or stop uplink transmission.

[0147] For example, if the reserved resource is a shared resource for terminal 1 and terminal 2, and terminal 1 plans to use the first type of FDSS for uplink transmission, while terminal 2 plans to use the second type of FDSS for uplink transmission, then terminal 1 can continue to use the first type of FDSS for uplink transmission, and terminal 2 can continue to use the second type of FDSS for uplink transmission; or,

[0148] Terminal 1 is preparing to use the second type of FDSS for uplink transmission, and Terminal 2 is preparing to use the third type of FDSS for uplink transmission. Terminal 1 and Terminal 2 can stop uplink transmission.

[0149] If the reserved resources are reserved for at least two terminals to share, and the terminal receives the sixth instruction information sent by the network device, the terminal performs uplink transmission according to the sixth instruction information. The sixth instruction information can be used to instruct the terminal to perform uplink transmission using the first transmission method, that is, uplink transmission without FDSS processing, or uplink transmission without extended FDSS processing, or uplink transmission with extended FDSS processing.

[0150] like Figure 6As shown, if multiple scheduled terminals (assuming two terminals) share an extended PRB during scheduling, the two terminals will reuse that PRB. This has little impact on the second type of FDSS, but a significant impact on extended FDSS using a repetitive approach, as it may result in significant out-of-band radiation, leading to strong interference and potentially exceeding the performance specifications stipulated in the RAN4 protocol. Therefore, these terminals may cancel their respective uplink transmissions. Alternatively, the situation may be handled as described in the previous embodiment. For example, for uplink transmissions that have not yet started, the network device can issue new instructions (such as the sixth instruction information) to the two terminals. The terminals can then perform unspread spectrum shaping FDSS transmission, not perform spectrum shaping FDSS transmission, or maintain the original state, respectively, to continue the uplink transmission process. Furthermore, since only the network device is aware of this sharing situation, and the terminals are unaware, if the network device determines that the situation has no significant impact, or if the network side believes that it is too late to modify the terminal's FDSS type, the network may not issue any instructions, and the terminals can continue the original uplink transmission process.

[0151] In the above embodiments, when the reserved resources are reserved resources that are reused by at least two terminals, uplink transmission can be performed, uplink transmission can be stopped, or the original uplink transmission process can be continued according to the new instructions sent by the network device.

[0152] In one embodiment, the method further includes:

[0153] If the first duration exceeds the duration threshold, the terminal stops uplink transmission; the first duration is the duration during which the terminal's circuitry used for FDSS processing is turned on or off.

[0154] Specifically, if the time for which the terminal's circuitry for FDSS processing is turned on or off is too long, exceeding a time threshold, the terminal may stop uplink transmission. The time threshold may be pre-configured or predefined.

[0155] In one embodiment, in order to ensure that the first duration of the terminal is less than the frequency domain scheduling delay and to ensure that the FDSS uplink transmission can proceed smoothly, the uplink transmission can be performed using FDSS, and the frequency domain scheduling delay can be increased. The target k2 value of TDRA in DCI is the sum of the initial k2 value and the first duration; the first duration is the duration during which the circuit used by the terminal for FDSS processing is turned on or off.

[0156] Specifically, if a network device sends a new scheduling instruction and the first duration is longer than the frequency domain scheduling delay, the terminal cannot process the new scheduling instruction and can only cancel the uplink transmission or continue the uplink transmission according to the previous process.

[0157] For the indication of spectrum shaping involving DCI scheduling, the k2 value in the TDRA table can be modified to take into account the influence of the waveform switching time in the frequency domain scheduling delay represented by k2, that is, to take into account the duration of the circuit for FDSS processing to be turned on or off, thus forming a new target k2 value.

[0158] If the k2 value still exceeds the duration threshold, the uplink transmission will be cancelled.

[0159] In the above embodiments, for uplink transmissions that perform FDSS processing and uplink transmissions that do not perform FDSS processing, it is necessary to enable or disable the circuit used for FDSS processing. Enabling or disabling the circuit involves a switching delay, which can be adjusted to meet the current uplink transmission requirements.

[0160] In one embodiment, the method further includes:

[0161] The terminal reports the types of FDSS it supports to the network device.

[0162] This step can be performed before step 101 or step 102.

[0163] Optionally, the terminal can also report that it does not support FDSS.

[0164] Specifically, before network device scheduling, the terminal can report its supported FDSS capabilities, i.e. the types of FDSS it supports. After receiving the report, if the network device has a higher protocol version, it can identify the terminal's capabilities and send higher-layer signaling, so that the terminal knows the target frequency domain resource information and performs the corresponding uplink transmission.

[0165] In other embodiments, the terminal may also not report its capabilities. In some scenarios, such as when a network device knows that all terminals in the network support the new protocol (i.e., the terminals support FDSS uplink transmission), the terminal may not report its capabilities.

[0166] like Figure 7 As shown, during the uplink FDSS process, the size and location information of the extended PRB can be obtained through the target frequency domain resource information included in the first indication information. Optionally, the network device sends out complete resource configuration information of the RRC, including the type of FDSS and the target frequency domain resource information. After receiving it, the terminal knows the type of FDSS and knows the size and frequency domain location of the PRB based on the target frequency domain resource information of the RRC.

[0167] After receiving an instruction from the network device, the terminal determines to use FDSS for uplink transmission, for example by issuing an instruction through the first message signaling, such as RRC signaling.

[0168] likeFigure 8 As shown, during uplink FDSS, the size and location information of the extended PRB can be obtained through the target frequency domain resource information. The network device can configure the first indication information in the resources of the first channel (such as PUCCH), using dynamic indication (e.g., PRI in DCI) or by activating the indication information through semi-static configuration (e.g., by using CS-RNTI for descrambling, setting the HARQ process to all 0s after success, setting the redundant version to "00", thereby implicitly activating the SPS PDSCH configuration and determining the resource index information) to indicate the configuration information of the first channel, enabling the terminal to be aware of the above information and perform corresponding uplink transmission. Optionally, the network device configures complete configuration information in the configuration information of the first channel, including the FDSS type and target frequency domain resource information. After receiving this information, the terminal knows the FDSS type and, based on the target frequency domain resource information of the RRC, knows the PRB size and frequency domain location.

[0169] like Figure 9 As shown, during uplink FDSS processing, the size and location information of the extended PRB can be obtained through the information of the target frequency domain resources mentioned above. The network device sends a first message signaling (e.g., RRC signaling). Optionally, the network device configures FDSS enabling or type information in the first message signaling. If the first message signaling includes FDSS enabling information, after receiving the first message signaling, the terminal determines the type of FDSS according to default rules. If extended FDSS processing is required, the size and location information of the extended PRB are determined according to default rules. If it is another type of FDSS, corresponding configuration and transmission preparation are performed. This default rule can be implicitly indicated by the extended TDRA table or implemented according to other default rules.

[0170] like Figure 10As shown, during uplink FDSS, the size and location information of the extended PRB can be obtained through the information of the target frequency domain resources. The network device configures the first indication information in the resources of the first channel (such as PUCCH), and uses dynamic indication (such as PRI in DCI) or semi-static configuration to activate the indication information (for example, by using CS-RNTI for descrambling, setting the HARQ process to all 0s after success, setting the redundant version to "00", thereby implicitly activating the configuration of SPSPDSCH and determining the resource index information) to indicate the configuration information of the first channel, or directly uses MAC-CE activation and deactivation to implicitly indicate the enable of the first indication information (such as PUCCH in half-cycle CSI), so that the terminal is aware of the above information and performs the corresponding uplink transmission. Optionally, the network device configures FDSS enable or type information in the first message signaling. If the first message signaling includes FDSS enabling information, after receiving the first message signaling, the terminal determines the type of FDSS according to the default rules. If extended FDSS processing is required, the terminal determines the extended PRB size and location information according to the default rules. If it is another type of FDSS, the terminal performs the corresponding configuration and transmission preparation. This default rule can be implicitly indicated by the extended TDRA table or implemented according to other default rules.

[0171] like Figure 11 As shown in Figure 11, during the scheduling process, if the network device does not recognize the capabilities reported by the terminal, or if the network device believes that spectrum shaping transmission is unnecessary, it can send an enabling negative message, i.e., disable the FDSS processing. Alternatively, as shown in Figure 11, it can choose not to provide feedback to save signaling. If the terminal does not receive the indication message, it will default to not using spectrum shaping transmission. For some networks, if spectrum shaping is not performed by default, the terminal will not perform FDSS processing by default, and the terminal may not report its own spectrum shaping capabilities.

[0172] like Figure 12 As shown, if during the scheduling process, Figure 12The indicated PRB may be cancelled by a Cancellation Indicator (CI). If this occurs, and uplink transmission is about to begin or has already begun, the terminal needs to cancel the uplink transmission on that frequency domain resource. If uplink transmission has not yet begun and sufficient time has been reserved after the CI indication, the network device can issue a new indication, such as the fifth indication information. The terminal then performs either spread-free spectrum shaping transmission or does not perform spectrum shaping transmission, and readjusts the transmission rate to continue the uplink transmission process. This new indication can be issued via DCI, pre-configured by the network device, or implicitly indicated via DCI. For example, if the RRC predefines the MCS level corresponding to a certain FDSS type, the specific FDSS type can be obtained through the MCS indicated by the DCI, and thus the corresponding resource configuration information can be obtained. The resource configuration information can also be pre-defined. For safety, the frequency domain resources reserved by the network device for FDSS uplink transmission can be idle resources, i.e., not used for other purposes. In other words, FDSS uplink transmission is not performed on the frequency domain resources reserved for other purposes in network equipment to avoid the above situation.

[0173] In one embodiment, such as Figure 5 As shown, the transmission method provided in this embodiment includes:

[0174] Step 100: The network device sends the first instruction information to the terminal;

[0196] Optionally, the network device sends a fourth indication message to the terminal, instructing the terminal to perform uplink transmission using the first transmission method; or, to process the transmission channel or signal using the first type of FDSS.

[0198] Optionally, the target frequency domain resource is not a resource that can be dynamically scheduled by the network device.

It is understood that the aforementioned modem processor may also not be integrated into processor 1010.

[0301] Among them, processor 1010 is used to acquire target frequency domain resources;

[0302] Based on the target frequency domain resources, the transmission channel or signal is subjected to FDSS spectrum shaping, and the processed transmission channel or signal is then transmitted uplink.

[0303] In this embodiment, the terminal's processor acquires the target frequency domain resources; performs FDSS (Frequency Direct Structuring) processing on the transmission channel or signal based on the target frequency domain resources, and performs uplink transmission on the processed transmission channel or signal. Since the data has undergone FDSS processing, the correlation between adjacent data in the data after FDSS processing is better than the correlation before FDSS processing, thus reducing PAPR (Parallel Per Parameter).

[0304] Optionally, the processor 1010 is specifically used for:

[0305] The target frequency domain resource is acquired based on the first indication information, which is sent by the network device. The first indication information includes at least one of the following: the FDSS enable information, the FDSS type information, and the target frequency domain resource information; the first indication information is sent in at least one of the following ways:

The first frequency domain resource is used to map the transmission channel or signal before FDSS processing, and the second frequency domain resource is a reserved resource.

[0314] In the above implementation, different types of FDSS have different target frequency domain resources. Therefore, when acquiring target frequency domain resources, the type of FDSS is first determined, and then the target frequency domain resources are acquired according to the type of FDSS, which makes the implementation simple.
