The following is a brief introduction to the principle of spectrum shaping FDSS:

After a group of discrete time-domain signals passes through the DAC module, the peak-to-average ratio of the output analog signal has a certain relationship with the correlation between the group of discrete time-domain signals. Assume that a set of discrete time-domain data signals y(n) is convolved with a set of time-domain discrete data d(n) in the time domain to obtain yd(n):

Let the peak-to-average ratios of the output signals of y(n) and yd(n) after DAC be PAPR1 and PAPR2 respectively, if d(n) is a set of designed weight coefficients, then the adjacent data of yd(n) The inter-correlation will be better than the correlation between adjacent data of y(n), so PAPR2 will be smaller than PAPR1. After a set of discrete time-domain data is convoluted with a set of designed discrete data, PAPR can be effectively reduced.

According to the convolution theorem, the convolution operation of two time domain signals can be equivalent to the point product operation of the two time domain signals in the frequency domain. Therefore, a group of discrete time-domain data signals are transformed into discrete frequency-domain data signals after DFT, and then point-multiplied by the designed spectrum shaping sequence, and then the time-domain signals after IDFT 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, so it is called spectrum shaping FDSS.

Furthermore, when performing FDSS transmission, a few adjacent physical resource blocks (Physical Resource Block, PRB) can be reserved to adjust the frequency domain waveform roll-off, obtain a smoother shaped waveform, optimize the d(n) coefficient, and obtain a better The low PAPR effect. Its implementation mainly includes two ways of reserving idle PRBs and reserving repeated PRBs.

Figure 2 shows reserved idle PRBs, and Figure 3 shows reserved repeated PRBs. In Figure 3, for example, the repeated information in the extended PRB on the left is the information of the fifth PRB in the frequency domain signal. The repetition information in the extended PRB is the information of the first PRB in the frequency domain signal.

Due to the existence of redundant RB numbers, the spectrum shaping waveform can achieve a smoother roll-off and reduce sharper jitter. As we all know, the roll-off of the waveform determines the difficulty of device implementation. Reserved PRB reduces the power at the peak and eases the degree of roll-off, which has a very good performance improvement effect and practical value.

The transmission method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

FIG. 4 is one of the schematic flowcharts of the transmission method provided by the embodiment of the present application. As shown in Figure 4, the transmission method provided in this embodiment includes:

Step 101, the terminal acquires target frequency domain resources;

Wherein, the target frequency domain resource is a frequency domain resource used by the terminal for uplink transmission, and the terminal may acquire the target frequency domain resource based on network device configuration, default configuration, or predefined rules. Wherein, the frequency domain resources may include: subcarriers or physical resource blocks (PRBs).

Step 102, the terminal performs spectrum shaping FDSS processing on the transmission channel or signal based on the target frequency domain resource, and performs uplink transmission on the processed transmission channel or signal.

Specifically, the terminal uses the target frequency domain resource to map the transmission channel or signal, that is, maps the time domain signal to a frequency domain signal, and then performs FDSS processing. FDSS processing can be regarded as multiplying the frequency domain signal by a raised cosine filter in the frequency domain filter, including but not limited to a raised cosine roll-off filter, and perform uplink transmission on the processed transmission channel or signal.

FDSS includes the following types:

The first type, that is, FDSS without extension;

The second type, as shown in Figure 2, is an extended FDSS that reserves idle resources;

The third type, as shown in Figure 3, is an extended FDSS that reserves duplicate resources;

For the second type of FDSS, in addition to the frequency domain resources used to transmit channels or signals, additional frequency domain resources can be scheduled, and there is no other information transmission on the frequency domain resources, which serve as guard bands. In this way, the terminal can put the out-of-band roll-off generated by shaping into the reserved frequency domain resource to achieve the purpose of smoothing the waveform.

For the third type of FDSS, in addition to the frequency domain resources used to transmit channels or signals, additional frequency domain resources can be scheduled, and the frequency domain resources have the same repeated information as the main lobe of the signal after FDSS processing, serving as guard bands. In this way, the terminal can put the out-of-band roll-off generated by shaping into the frequency domain resources with repetitive information, so as to achieve the purpose of smoothing the waveform. Filling the reserved frequency domain resources with repeated information can ensure the orthogonality between subcarriers and reduce intercarrier interference.

In the method of this embodiment, the terminal obtains the target frequency domain resource; the terminal performs spectrum shaping FDSS processing on the transmission channel or signal based on the target frequency domain resource, and performs uplink transmission on the processed transmission channel or signal. After the FDSS processing, the FDSS The correlation between adjacent data in the processed data will be better than the correlation before FDSS processing, so PAPR can be reduced.

In an embodiment, step 101 may be implemented in the following manner:

The terminal acquires the target frequency domain resource based on the first indication information, the first indication information is sent by the network device, and the first indication information includes at least one of the following: FDSS enabling information, FDSS type information, and target frequency domain resource information;

Wherein, the first indication information is sent in at least one of the following ways:

The first message signaling carries the first indication information; or,

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

Specifically, as shown in FIG. 5, as in step 100, the network device sends the first indication information to the terminal, and the first indication information may be used to indicate resource configuration information for FDSS processing and uplink transmission. Based on the first indication information, the terminal acquires The target frequency domain resource, the first indication information includes at least one of the following: FDSS enabling information, FDSS type information, and target frequency domain resource information;

Wherein, the first indication information is sent in at least one of the following ways:

One way: the first message signaling carries the first indication information;

Wherein, the first message signaling is, for example, high-layer signaling such as radio resource control (Radio Resource Control, RRC) signaling. In other embodiments, it may also be sent through other signaling, which is not limited in this embodiment of the present application.

Another way: the configuration information of the first channel carries the first indication information, and indicates the terminal the configuration information of the first channel through the second indication information;

Wherein, the first channel is, for example, a physical uplink control channel (Physical Uplink Control Channel, PUCCH), or a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), etc.

In addition to carrying: at least one of FDSS enabling 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, network equipment The index information of the configuration information of the first channel may be indicated to the terminal through the second indication information.

Indicate the index information of the configuration information of the first channel of the terminal through the second indication information, the second indication information is carried by, for example, downlink control information (Downlink Control Information, DCI), for example, through the original indication field of DCI, the newly added Direct indication of the indication field, or implicit indication, wherein the implicit indication includes but is not limited to semi-static configuration combined with DCI dynamic indication, such as network equipment pre-configuring or pre-defining the first channel carrying the first indication information The information of the configuration information, the configuration information is indicated by means of the indication field in the DCI.

Wherein, the second indication information may also be indicated through the second message signaling, that is, the network device configures the configuration information in a semi-static manner, for example, configures periodic configuration information that can be used to carry the first indication information, and then passes the second message The signaling indicates the index information of the configuration information, for example, the index information of the configuration information is indicated by the configuration information of the periodic channel state information (Channel State Information, CSI) or the configuration information of the uplink scheduling request (Scheduling Request, SR).

Still another way: the configuration information of the first channel carries the first indication information, and the configuration information of the first channel is obtained through an activation instruction of a Media Access Layer (Media Access Control, MAC) control unit (Control Element, CE) of.

Specifically, when the semi-static CSI is transmitted in the PUCCH, the SP CSI reporting on PUCCH Activation/Deactivation MAC CE is used to activate or deactivate it, and the S _i field in the MAC CE determines the indication mode of the configuration information of the first channel , i represents the number of bits used for indication in the S _i field. Through the indication of the first i bits, the index information (Id) of the CSI-Report Config configured as semiPersistentOnPUCCH can be obtained, and the S _i value of the i+1th bit is used to indicate activation or deactivation. For example, setting S _i+1 to 1 means activating the CSI-Report Config configuration information configured as semiPersistentOnPUCCH to perform semi-persistent CSI transmission on the PUCCH.

The specific indication method is that the CSI-Report Config configured as semiPersistentOnPUCCH corresponds to a reportConfigId, the smallest of these Id indexes is indicated by S ₀ in MAC-CE, the second smallest is indicated by S ₁ in MAC-CE, and so on , for example, there are 3 semiPersistentOnPUCCH configuration information, then S ₂ corresponds to the configuration corresponding to the largest ID value. Then S ₃ corresponds to the activation or deactivation indication of the MAC-CE, for example, 1 indicates activation and 0 indicates deactivation. After the Id index information is indicated through S _i , the CSI-Report Config corresponding to the Id will include PUCCH-CSI-Resource configuration information, including the PUCCH resource configuration index, so as to obtain the configuration information of the first channel.

In the above embodiments, the network device configures resource information for FDSS processing and uplink transmission for the terminal through the first indication information, which may be directly or implicitly indicated, and the implementation method is simple and flexible.

In an embodiment, the terminal determines the type of FDSS based on the first indication information, and "obtaining target frequency domain resources" can be implemented in the following manner:

When the type of FDSS is the first type, the terminal acquires a first frequency domain resource, and the first frequency domain resource is used to map a transmission channel or signal before FDSS processing; the target frequency domain resource includes the first frequency domain resource;

When the type of FDSS is the second type or the third type, the terminal obtains 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, and the first frequency domain resource includes the first frequency domain resource and the second frequency domain resource. The domain resources are used to map transmission channels or signals before FDSS processing, and the second frequency domain resources are reserved resources.

Specifically, when the type of FDSS is the first type, that is, in the case of no extended FDSS, the target frequency domain resource includes a first frequency domain resource, and the first frequency domain resource is used to map the transmission channel before FDSS processing The or signal, that is, the first frequency domain resource is used to transmit spectrum shaped main lobe information.

When the type of FDSS is the second type or the third type, that is, in the case of extended FDSS, the target frequency domain resource includes a first frequency domain resource and a second frequency domain resource, and the first frequency domain resource is used for Mapping the transmission channel or signal before FDSS processing, the second frequency domain resources are reserved resources, and the second frequency domain resources can be used for out-of-band roll-off generated by transmission spectrum shaping.

In the above embodiments, different types of FDSS have different target frequency domain resources. Therefore, when acquiring target frequency domain resources, first determine the type of FDSS, and then acquire target frequency domain resources according to the type of FDSS. The implementation scheme is simple.

Optionally, as shown in FIG. 2, when the type of FDSS is the second type, the reserved resources are not used to map information in the transmission channel or signal;

Specifically, for the second type of FDSS, the reserved resource is an idle resource; there is no other information transmission on the reserved resource, which acts as a guard band. In this way, the terminal can put the out-of-band roll-off generated by spectrum shaping into the reserved resources to achieve the purpose of smoothing the waveform.

Optionally, as shown in FIG. 3 , when the type of FDSS is the third type, reserved resources are used to map part of the repeated information in the transmission channel or signal.

Specifically, for the third type of FDSS, the reserved resource has the same repetitive information as the main lobe of spectrum shaping, serving as a guard band. In this way, the terminal can put the out-of-band roll-off generated by spectrum shaping into the frequency domain resources with repetitive information, so as to achieve the purpose of smoothing the waveform.

In the above embodiments, the reserved resources can serve as guard bands, and the terminal can put the out-of-band roll-off generated by spectrum shaping into the reserved frequency domain resources, so as to achieve the purpose of smoothing waveforms.

In an embodiment, "determining the type of FDSS" can be implemented in the following manner:

In the case where the first indication information includes FDSS enabling information, and the FDSS enabling information is used to indicate enabling FDSS, the terminal determines the type of FDSS according to preset configuration information; or,

If the first indication information includes FDSS type information, the terminal determines the FDSS type according to the FDSS type information.

Specifically, when the first indication information includes FDSS enabling information, and the FDSS enabling information is used to indicate enabling FDSS, that is, the terminal needs to perform FDSS processing before performing uplink transmission, so the terminal first determines the type of FDSS, If the first indication information does not include the FDSS type information, for example, determine the FDSS type based on preset configuration information, and perform uplink transmission based on a default configuration or rule corresponding to the determined FDSS type. Wherein, the preset configuration information is, for example, pre-configured information of the network device, or default configuration information, or predefined configuration information.

In the case where the first indication information includes FDSS type information, if the first indication information does not include target frequency domain resource information, perform uplink transmission based on preset frequency domain resources, for example, perform uplink transmission based on default configuration or rules; if The first indication information includes the information of the target frequency domain resource, and uplink transmission is performed based on the target frequency domain resource. For example, the target frequency domain resource can be used to map the transmission channel or signal, and then FDSS processing is performed, and then the FDSS processed transmission channel or The signal is transmitted upstream.

In an embodiment, the step "the terminal obtains the target frequency domain resource" can be implemented in the following manner:

If the first indication information does not include information about the target frequency domain resource, the terminal acquires the target frequency domain resource based on preset configuration information;

If the first indication information includes information about the target frequency domain resource, the terminal acquires the target frequency domain resource based on the information about the target frequency domain resource.

Specifically, for the extended FDSS, when the first indication information includes the information of the target frequency domain resource, the terminal acquires the target frequency domain resource based on the information of the target frequency domain resource, that is, acquires the first frequency domain resource and the second frequency domain resource. Domain resources.

If the first indication information does not include information about the target frequency domain resource, the terminal acquires the target frequency domain resource based on the preset configuration information, that is, acquires the first frequency domain resource and the second frequency domain resource. Wherein, the preset configuration information is, for example, pre-configured information of the network device, or default configuration information, or predefined configuration information.

For the FDSS without extension, the way to obtain the first frequency domain resource is similar to the above solution, and will not be repeated this time.

Optionally, the method also includes:

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

Specifically, the third indication information may be carried by downlink control information DCI, for example, through the original indication field of DCI, the newly added indication field direct indication, or implicit indication, wherein the implicit indication is such as semi-static configuration, combined with DCI dynamic It can be realized by indicating, for example, the network device pre-configures or pre-defines the second frequency domain resource, and the second frequency domain resource is determined by means of the indication field in the DCI, for example, the second frequency domain resource is determined by means of the indication field in the FDRA of the DCI.

Optionally, the number of PRBs included in the second frequency domain resource is less than or equal to the maximum number of PRBs N, where N may be specified by the protocol, for example, the maximum number of PRBs of the PUCCH specified in Release 15 cannot exceed 16 RB; for example The maximum number of PRBs of the PUSCH cannot exceed the maximum value of the BWP (the maximum number of PRBs is also different for each subcarrier interval).

In the above embodiments, several ways of determining the target frequency domain resource are provided, and the frequency domain resource of the extended FDSS may be indicated directly or implicitly.

In an embodiment, step 102 may be implemented in the following manner:

Based on the type of FDSS, the terminal uses the target frequency domain resource to map the transmission channel or signal and perform FDSS processing.

Specifically, based on the type of FDSS, the terminal uses the target frequency domain resource to map the transmission channel or signal, that is, based on the type of FDSS, the time domain signal is mapped to the frequency domain signal, and then FDSS processing is performed. FDSS processing can be regarded as a frequency domain signal. The signal in the frequency domain is multiplied by a raised cosine filter in the frequency domain, and the processed transmission channel or signal is transmitted upstream.

In the above embodiments, due to the FDSS processing, the correlation between adjacent data in the data after the FDSS processing is better than the correlation before the FDSS processing, so the PAPR can be reduced.

In an embodiment, the transmission channel satisfies at least one of the following indicators:

The error vector magnitude (Error Vector Magnitude, EVM) of the modulation mode corresponding to the transmission channel is less than or equal to the first threshold, wherein the first threshold is the maximum value of the EVM of the modulation mode corresponding to the first transmission mode;

The maximum power fallback value (Maximum Power Reduction, MPR) of the modulation mode corresponding to the transmission channel is less than or equal to the second threshold value, wherein, the second threshold value is the maximum value of the MPR of the modulation mode corresponding to the first transmission mode;

The in-band radiation power (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;

The out-of-band radiated power (Out-of-band Energy, OBE) corresponding to the transmission channel is less than or equal to the fourth threshold, where the fourth threshold is greater than or equal to the maximum value of the OBE corresponding to the first transmission mode;

The transmit power of the terminal is less than or equal to the fifth threshold and greater than or equal to the sixth threshold, where the fifth threshold is the maximum value of the transmit power of the terminal corresponding to the first transmission mode, and the sixth threshold is the maximum value of the transmit power of the terminal corresponding to the first transmission mode. minimum value of power;

Wherein, the first transmission mode is a transmission mode that does not perform spectrum shaping FDSS processing.

The aforementioned thresholds may be specified by the protocol, or pre-configured, such as the aforementioned index values specified by the RAN4 radio frequency index.

In one embodiment, the method may also include the following steps:

The terminal receives the fourth indication information sent by the network device, and the fourth indication information is used to indicate to cancel the target frequency domain resource; this step is not in sequence with steps 101 and 102.

The terminal adopts the following methods for uplink transmission:

One way: the terminal stops performing uplink transmission.

Specifically, in the case of receiving an instruction from the network device to cancel the target frequency domain resource, the use of the target frequency domain resource for uplink transmission may be stopped.

Optionally, the target frequency domain resources are not dynamically schedulable resources by the network device.

Specifically, when configuring resources for the terminal, the network device avoids using frequency domain resources for other purposes, for example, resources that can be dynamically scheduled by the network device cannot be configured as the target frequency domain resources.

Another way: according to the fifth indication information sent by the network device, the terminal performs uplink transmission on the transmission channel or signal based on the target frequency domain resources by using the first transmission mode.

Wherein, the fifth indication information is used to indicate at least one of the following: FDSS enabling information, FDSS type information, and target frequency domain resource information.

Specifically, in the case of receiving an instruction from the network device to cancel the target frequency domain resource, if the fifth instruction information sent by the network device is received again, for example, the fifth instruction information includes FDSS enabling information, and FDSS is not enabled, the terminal According to the indication of the fifth indication information, the uplink transmission mode without FDSS processing may be used for transmission, and at this time, the uplink transmission mode may use the target frequency domain resources indicated by the fifth indication information.

Still another way: according to the fifth indication information sent by the network device, the terminal processes the transmission channel or signal based on the target frequency domain resource using the first type of FDSS to process the channel or signal, and performs uplink processing on the processed transmission channel or signal transmission.

Specifically, in the case of receiving an instruction from the network device to cancel the target frequency domain resource, if the fifth instruction information sent by the network device is received again, for example, the fifth instruction information includes FDSS type information, and the type indicated by the type information is the first One type of FDSS, the terminal can use the first type of FDSS to process the channel or signal according to the indication of the fifth indication information, that is, use the non-extended FDSS to process the channel or signal, and process the processed transmission channel or signals for uplink transmission.

In an embodiment, the fifth indication information is sent in at least one of the following ways:

The original indication field of the downlink control information DCI and the indication field added in the downlink control information DCI carry the fifth indication information; or,

The DCI implicitly indicates the fifth indication information.

Specifically, the fifth indication information may be carried by downlink control information DCI, for example, through the original indication field of DCI, the newly added indication field or implicit indication, wherein the implicit indication is such as semi-static configuration, combined with the implicit indication of DCI , the fifth indication information can be determined, for example, the network device pre-configures or pre-defines the FDSS type corresponding to a certain modulation mode, and the modulation mode can be determined by means of the indication field in the DCI, and then the FDSS type can be determined.

In the above embodiments, when the network device requests to cancel the uplink transmission based on the target frequency domain resource, the current uplink transmission can be stopped, or the uplink transmission can be performed based on a new instruction from the network device, which is more flexible.

In other embodiments, optionally, the fourth indication information is used to indicate the cancellation of reserved resources in the target frequency domain resource, that is, the terminal can perform FDSS uplink transmission without extension, or use the first transmission method to perform uplink transmission, namely FDSS uplink transmission is not performed.

In an embodiment, step 102 may be implemented in the following ways:

When the reserved resources are reserved resources multiplexed by at least two terminals, 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 use Uplink transmission is performed in the first transmission mode; or, FDSS is used to process the transmission channel or signal and perform uplink transmission;

In the case that the reserved resource is the reserved resource multiplexed by at least two terminals, the terminal performs uplink transmission on the processed transmission channel or signal.

When the reserved resources are reserved resources multiplexed by at least two terminals, the terminals stop performing uplink transmission.

Specifically, when the reserved resources are reserved resources multiplexed by at least two terminals, the reserved resources, that is, the second frequency domain resources, such as idle resources or resources for transmitting repetitive information in Figure 2 and Figure 3, the terminal The original type of FDSS can be used to process the channel or signal and perform uplink transmission, or stop uplink transmission.

For example, the reserved resources are reserved resources multiplexed by Terminal 1 and Terminal 2. Terminal 1 is going to use the first type of FDSS for uplink transmission, and Terminal 2 is going to use the second type of FDSS for uplink transmission. Terminal 1 can continue to use The first type of FDSS is used for uplink transmission, and the terminal 2 may continue to use the second type of FDSS for uplink transmission; or,

Terminal 1 prepares to use the second type of FDSS for uplink transmission, terminal 2 prepares to use the third type of FDSS for uplink transmission, and terminal 1 and terminal 2 may stop performing uplink transmission.

In the case where the reserved resources are reserved resources multiplexed by at least two terminals, if the terminal performs uplink transmission according to the sixth indication information when receiving the sixth indication information sent by the network device, the sixth indication information may It is used to instruct the terminal to use the first transmission method to perform uplink transmission, that is, uplink transmission without FDSS processing, or uplink transmission without extended FDSS processing, or uplink transmission with extended FDSS processing.

As shown in FIG. 6 , if during the scheduling process, multiple scheduled terminals (assumed to be two terminals) share one extended PRB, the two terminals will multiplex the PRB. It has little impact on the second type of FDSS, but it has a greater impact on the extended FDSS method that adopts repeated methods, because there may be large out-of-band radiation, resulting in strong interference, and may exceed the performance specified in the RAN4 agreement index. Therefore, these terminals may cancel their respective uplink transmissions. Of course, it is also possible to perform processing according to the situation of the foregoing embodiments. For example, for uplink transmissions that have not yet started transmission, the network device can issue new instructions (such as sixth instruction information) to the two terminals, and the terminals perform wireless operations respectively according to the new instructions. The extended spectrum shaping FDSS transmission either does not perform the spectrum shaping FDSS transmission or maintains the original state, so as to continue the uplink transmission process. In addition, since only the network equipment is aware of the sharing situation, but the terminal is not aware of it, if the network equipment judges that the situation has no obvious impact, or the network side thinks that it is too late to modify the FDSS type of the terminal at this time, the network may not give any instructions, and the terminal The original uplink transmission process can be continued.

In the above embodiments, when the reserved resources are reserved resources multiplexed by at least two terminals, the uplink transmission may be performed according to the new instruction sent by the network device, or the uplink transmission may be stopped, or the original uplink transmission process may be continued.

In one embodiment, the method also includes:

When the first duration exceeds the duration threshold, the terminal stops uplink transmission; the first duration is a duration for enabling or canceling a circuit for the terminal to perform FDSS processing.

Specifically, if the time for the terminal to open or cancel the circuit for FDSS processing is long and exceeds a time threshold, the terminal may stop uplink transmission, and the time threshold may be pre-configured or predefined.

In an embodiment, in order to make the first duration of the terminal shorter than the frequency domain scheduling delay and ensure the smooth progress of FDSS uplink transmission, FDSS can be used for uplink transmission, and the frequency domain scheduling delay can be increased. The target k2 of TDRA in DCI The value is the sum of the initial k2 value and the first duration; the first duration is the duration for enabling or canceling the circuit for the terminal to perform FDSS processing.

Specifically, assuming that the network device sends a new scheduling instruction, if the first time length is greater than the frequency domain scheduling delay, the terminal cannot process according to the current new scheduling instruction, and can only cancel the uplink transmission, or continue to perform uplink according to the previous processing process transmission.

For the indication of spectrum shaping involved in DCI scheduling, the k2 value in the TDRA table can be modified, and the impact of waveform switching time is taken into account in the frequency domain scheduling delay represented by k2, that is, the circuit for FDSS processing is turned on or canceled time to form a new target k2 value.

If the k2 value still exceeds the duration threshold, the uplink transmission is canceled.

In the above embodiments, for uplink transmission with FDSS processing and uplink transmission without FDSS processing, it is necessary to open or cancel the circuit for FDSS processing, and there is a switching delay in opening or canceling the circuit, and the switching delay can be adjusted Adjustments are made to meet the current uplink transmission requirements.

In one embodiment, the method also includes:

The terminal reports the supported FDSS type to the network device.

Wherein, this step may be performed before step 101 or step 102 .

Optionally, the terminal may also report that it does not support FDSS.

Specifically, before network equipment scheduling, the terminal can report the FDSS capability it supports, that is, the type of FDSS supported. After the network equipment receives it, if it is a network equipment with a higher protocol version, it can identify the capability of the terminal and perform high-level signaling. After receiving it, the terminal knows the information of the target frequency domain resource and performs corresponding uplink transmission.

In other embodiments, the terminal may not report the capability. In some scenarios, for example, the network device knows that all terminals in the network support the new protocol, that is, the terminal supports FDSS uplink transmission, and the terminal may not report the capability.

As shown in FIG. 7 , in the process of performing the uplink FDSS, the size and position information of the extended PRB can be obtained through the information of the target frequency domain resource included in the first indication information. Optionally, the network device sends the complete RRC resource configuration information, including the type of FDSS and the information of the target frequency domain resource. After receiving it, the terminal knows the type of FDSS, and knows the PRB size according to the information of the target frequency domain resource of RRC with the frequency domain location.

After receiving the instruction sent by the network device, the terminal determines to use FDSS for uplink transmission, for example, sends the instruction through first message signaling, such as RRC signaling.

As shown in FIG. 8 , in the process of performing the uplink FDSS, the size and location information of the extended PRB can be obtained through the information of the target frequency domain resource. The network device may configure the first indication information in the resource of the first channel (such as PUCCH), use dynamic indication (for example, PRI in DCI) or semi-statically configure activation indication information (for example, use CS-RNTI to decompose After successful interference, configure the HARQ process as all 0, and set the redundancy version as "00", thereby implicitly activating the configuration of SPS PDSCH, and determining the resource index information) to indicate the configuration information of the first channel, so that the terminal knows The above information and perform corresponding uplink transmission. Optionally, what the network device configures in the configuration information of the first channel is the complete configuration information, the type of FDSS and the information of the target frequency domain resources. The information is aware of PRB size and frequency domain location.

As shown in Figure 9, in the process of performing uplink FDSS, the size and location information of the extended PRB can be obtained through the information of the above-mentioned target frequency domain resources. The network device sends the first message signaling (for example, RRC signaling). Optionally, what the network device configures in the first message signaling is FDSS enabling or type information. If the FDSS enabling information included in the first message signaling, after receiving the first message signaling, the terminal judges the type of FDSS according to the default rules, and if it needs to perform extended FDSS processing, judges the extended PRB size and location information according to the default rules , if it is another type of FDSS, perform corresponding configuration and transmission preparations. The default rule can be implemented through the implicit indication of the extended TDRA table, or according to other default rules.

As shown in FIG. 10 , in the process of performing the uplink FDSS, the size and location information of the extended PRB can be obtained through the above target frequency domain resource information. The network device configures the first indication information in the resources of the first channel (such as PUCCH), and uses a dynamic indication (for example, PRI in DCI) or a semi-static way of configuring the activation indication information (for example, by using CS-RNTI for descrambling, After success, configure the HARQ process as all 0, and set the redundancy version as "00", thereby implicitly activating the configuration of the SPS PDSCH, and determining the resource index information) to indicate the configuration information of the first channel, or directly use the MAC - The manner of CE activation and deactivation implicitly indicates the enablement of the first indication information (for example, the PUCCH of the half-period CSI), so that the terminal knows the above information and performs corresponding uplink transmission. Optionally, what the network device configures in the first message signaling is FDSS enabling or type information. If the FDSS enabling information included in the first message signaling, after receiving the first message signaling, the terminal judges the type of FDSS according to the default rules, and if it needs to perform extended FDSS processing, judges the extended PRB size and location information according to the default rules , if it is another type of FDSS, perform corresponding configuration and transmission preparations. The default rule can be implemented through the implicit indication of the extended TDRA table, or according to other default rules.

As shown in Figure 11, during the scheduling process, if the network device does not recognize the capability reported by the terminal, or if the network device believes that spectrum shaping transmission is not required, it can issue a negative message of enabling, that is, the FDSS processing is not enabled, or Feedback may not be performed as shown in Figure 11 to save signaling. If the terminal does not receive the indication information, it does not use spectrum shaping transmission by default. For some networks, if spectrum shaping is not performed by default, the terminal does not perform FDSS processing by default, and the terminal may not report its own spectrum shaping capability.

As shown in FIG. 12, if during the scheduling process, the PRB shown in FIG. 12 may be instructed by a cancellation indicator (Cancelation Indicator, CI) to cancel the transmission on the corresponding PRB and subcarrier. After this situation occurs, if the uplink transmission is about to start or has already started, the terminal needs to cancel the uplink transmission of the frequency domain resource. If the uplink transmission has not started at this time, and enough time has been reserved after the CI indication, the network device can issue a new indication, such as the fifth indication information, and the terminal performs spectrum shaping transmission without extension or does not perform spectrum shaping according to the new indication. Spectrum shaping transmission, and re-adjusting the code rate of transmission, so as to continue the process of uplink transmission. The new indication can be issued through DCI, pre-configured through network equipment, or implicitly indicated through DCI. For example, the RRC predefined MCS level corresponds to a certain type of FDSS, and the specific MCS indicated by DCI can be obtained. The type of the FDSS, and then obtain the corresponding resource configuration information, where the resource configuration information may also be predefined. For the sake of prudence, the frequency domain resources reserved by the network equipment for FDSS uplink transmission may be idle resources, that is, not used for other purposes. That is, the FDSS uplink transmission is not performed on the frequency domain resources reserved by the network equipment for other purposes, so as to avoid the occurrence of the above situation.
